Pro Tax release notes

This is the first release of Pro Tax T1 and FX for the 2026-taxation year.

Forms for the 2026-taxation year aren't released by the CRA at this time. All in-product forms that are not yet released display a banner that reads, "This form is currently under review". PDF preview will also be unavailable. The final version will be available in a future release.

Note: We recommend that discounters in provinces that provide refundable tax credits don't use this release to begin entering data for their clients.

T1 - Personal Taxes

2025–2026 Pro Tax to Pro Tax carry-forward preview

This early version of the Pro Tax 2026 T1 carries forward information from Pro Tax 2025 T1 returns to create new 2026 ProTax returns (for preview purposes only).

BC Family Benefit – Disability Supplement

British Columbia has added a new Disability Supplement to the BC Family Benefit for 2026: families with a child who qualifies for the disability tax credit can receive up to an extra $500 a month, gradually reduced once family net income passes $50,000. This is calculated automatically as part of the Canada Child Benefit, on ProTax's BC Family Benefit worksheet (T1BCCTB).

T777Auto, BusAuto – 2026 Vehicle Expense Rates

The tax-exempt per-kilometre allowance for employees and self-employed individuals who use a personal vehicle for business purposes rises to $0.73/km for the first 5,000 km and $0.67/km after that (territories: $0.77/km and $0.71/km). The capital cost limit for eligible Class 10.1 vehicles purchased in 2026 increases to $39,000 plus applicable taxes, up from $38,000. The maximum deductible lease cost stays at $1,100 per month, before tax, for new leases entered into in 2026; the vehicle-cost threshold used in the CRA's lease-cost proration formula rises in step with the higher CCA ceiling, to $45,882 from $44,706.

Asset and CCA schedules – Immediate Expensing (DIEP) Removed

The temporary Immediate Expensing measure (DIEP) has expired. The related fields and checkboxes have been removed from the CCA and asset forms for self-employment, business, farming, fishing, and resource income (T2125, T2121, T2042, T776, T1163/T1273, and the Resource schedules).

Removed worksheet:

• Authorize a Representative (T1013) and Cancel Authorization (T1013X)

T2 - Corporate Taxes:

S500 – Ontario Corporation Tax Calculation

The Government of Ontario tabled Bill 97, Plan to Protect Ontario Act (Budget Measures), 2026, which decreased the small business corporate income tax rate from 3.2% to 2.2%, effective July 1, 2026. Bill 97 received Royal Assent on April 24, 2026. As a result, the Ontario small business deduction rate increases from 8.3% to 9.3%. Part 2 and Part 4 have been updated in the CRA's (26) revision, applying each rate to its own period with day-count proration for taxation years that straddle July 1, 2026. 

Schedule 5 – Tax Calculation Supplementary, Corporations

A new line has been added for British Columbia's Manufacturing and Processing Tax Credit, feeding into the province's refundable-credit subtotal.

S5NL (S307) – Newfoundland and Labrador Corporation Tax Calculation

The Government of Newfoundland and Labrador tabled Bill 16, An Act to Amend the Income Tax Act, 2000, which decreases the small business corporate income tax rate in stages: from 2.5% to 2.0% effective January 1, 2026, to 1.5% effective January 1, 2027, and to 1.0% effective January 1, 2028. Bill 16 received Royal Assent on June 2, 2026. The Part 2 rate bands and day-count proration have been updated for the 2026 and later tax years to apply the new rates as they take effect.

T661 – Scientific Research and Experimental Development (SR&ED) Expenditures Claim

The form has been updated to reflect the latest 2026 version, including the reporting of capital expenditures in Part 4. Schedule 32 Assist has also been updated with a new column to support the Alberta Innovation Employment Grant on AS29.

AS29 / AS29List – Alberta Innovation Employment Grant

Eligible expenditures for the Innovation Employment Grant exclude capital expenditures made after December 15, 2024. Line 003 now draws the federal SR&ED amount from line 557 of federal Form T661 for tax years ending after December 15, 2024, and continues to use line 559 for tax years ending on or before that date, so that ineligible capital expenditures are excluded from both the base amount and total eligible expenditures. The line 011 add-back and the related AS29List allocation reconciliations follow the same cutoff, and the associated audit messages have been updated to reference line 559 or 557 as applicable.

Minor form updates:

• S5
• S572
• RD-222

FX - Forms and Slips

New 2026 FX module

ProTax 2026 FX is now available. Those wishing to file the 2026 slips now should use Pro Tax FX 2025  and manually override the year to 2026.

Slip filing in the 2026 module will be enabled in a future release once the 2026 slips have been updated.

Carry forward from 2025 to 2026

Pro Tax 2026 FX carries forward information from 2025 files created with Pro Tax 2025 FX

T661 – Scientific Research and Experimental Development (SR&ED) Expenditures Claim 

The form has been updated to reflect the latest 2026 version, which introduces the reporting of capital expenditures for depreciable property acquired after December 15, 2024. New parts have been added to report these capital expenditures and expenditures on shared-use-equipment. Current and capital amounts are now reported in separate columns and flow independently into the qualified expenditure and investment tax credit calculations. 

GST524 – GST/HST New Residential Rental Property Rebate Application

The form has been updated to reflect the latest 2026 version, which introduces the Ontario enhanced new residential rental property (ENRRP) rebate. Page 2 now includes an indicator for claiming the ENRRP rebate, the construction start and substantial completion dates, and a consent block for sharing information for the Ontario new home affordability payment. Any Ontario new residential rental property rebate already claimed is now reported separately and reduces the rebate calculated in Parts D and E. Note that provincial rebate schedules, including the GST524 Ontario Rebate Schedule (Form RC7524-ON), aren't supported by ProTax and must be completed separately.

GST525 – Supplement to the New Residential Rental Property Rebate Application

The form has been updated to reflect the latest 2026 version, which supports the Ontario enhanced new residential rental property (ENRRP) rebate. Both the multiple-unit and co-op rebate calculations now include a new entry for any Ontario new residential rental property (NRRP) rebate already claimed for the residential rental property, whether by the claimant or by another person. This amount reduces the total rebate calculated in each part. The rebate totals section for multiple-unit claims no longer reports a purpose-built rental housing amount, since those claimants don't complete the per-unit rebate calculation chart.

T1145 – Agreement to Allocate Assistance for SR&ED Between Persons Not Dealing at Arm's Length

The form has been updated to reflect the latest 2026 version. The assistance allocated on line 010 is now broken down between current expenditures and capital expenditures on lines 015 and 020, so that each amount is reported in the correct column of the transferee's T661.

T1146 – Agreement to Transfer Qualified Expenditures Incurred in Respect of SR&ED Contracts Between Persons Not Dealing at Arm's Length

The form has been updated to reflect the latest 2026 version. The qualified expenditures transferred on line 010 are now broken down between current expenditures and capital expenditures on lines 015 and 020, so that each amount is reported in the correct column of the T661 for both the transferor and the transferee.

GST190 – GST/HST New Housing Rebate Application for Houses Purchased from a Builder

The form has been updated to reflect the latest 2026 version, which introduces the Ontario enhanced new housing rebate (ENHR) and the Ontario new home affordability payment (ONHAP). Part A now includes a certification that the claimant is claiming the Ontario ENHR, along with claimant consent blocks for sharing information with the Province of Ontario in support of the ONHAP, covering both the case where the payment was assigned to the builder and the case where it wasn't. Part D includes a corresponding builder consent block for assigned payments. Each of the three rebate calculation sections now includes a new entry for any Ontario first-time home buyers' rebate already claimed for the house, whether by the claimant or by another person, and this amount reduces the total rebate amount in the section.

TD1NL – Newfoundland and Labrador Personal Tax Credits Return

The basic personal amount and infirm dependant amount both increase from $11,188 to $13,094 for 2026.

• T2 paper and internet filing is certified for Federal corporate tax returns

Schedule 3 – Dividends Received, Taxable Dividends Paid, and Part IV Tax Calculation 

Schedule 3 has been updated to reflect two changes introduced by CRA. A new question has been added to Section 2 (line 100) allowing a corporation to self-identify as exempt from Part IV tax under subsection 186.1(b)(ii) or (vii) of the Income Tax Act. This enables qualifying corporations — such as certain Crown corporations and tax-exempt entities — to indicate their exemption status directly on the schedule.

Additionally, a new column (line 235) has been added to the dividend detail table in Part 1 to capture taxable dividends that are deductible from income under paragraph 113(1)(c) of the Act, which applies to dividends received from foreign affiliates. The column labels throughout the table have been updated accordingly.

Schedule 5 – Tax Calculation Supplementary – Corporations

Schedule 5 has been updated to reflect legislative changes affecting Ontario and Nova Scotia tax calculations.

For Ontario corporations, two new lines have been added. Line 421 captures the non-refundable portion of the Ontario Made Manufacturing Investment Tax Credit (OMMITC) for the purposes of calculating Ontario corporate income tax payable. Additionally, a new line has been added for the Ontario Shortline Railway Investment Tax Credit (OSRITC). Introduced in the 2024 Ontario Budget and effective for eligible expenses incurred between May 15, 2025, and January 1, 2030, this new 50% refundable corporate income tax credit supports shortline rail operators. It provides up to $8,500 per track mile annually for track maintenance, rehabilitation, and infrastructure improvements in Ontario. 

To claim the credit, eligible corporations must first obtain a Certificate of Eligibility from the Ontario Ministry of Transportation. The refundable credit is calculated and claimed on Schedule 5 on Line 476, which then flows to Line 812 of the T2 Jacket.

For Nova Scotia, line 550 (provincial political contribution tax credit) has been removed from the total of Nova Scotia non-refundable tax credits.

Schedule 8, S8 Lease and Capital Cost Allowance (CCA) worksheets

The Schedule 8, Schedule 8 Lease, S8Class and corresponding Alberta worksheets have been updated to reflect the measures introduced in Bill C-15. The Bill reinstates the accelerated investment incentive, now called the Reaccelerated Investment Incentive (RIIP). It also reinstates immediate expensing for certain capital cost allowance (CCA) classes. The RIIP and immediate expensing applies to qualifying property acquired on or after January 1, 2025 and available for use before 2030. The measure would be phased out starting in 2030, and fully eliminated after 2033.

Productivity-enhancing assets: An additional enhanced first-year allowance for new additions of property to CCA Classes 44, 46, and 50 acquired after April 15, 2024, and available for use before January 1, 2027. These additions would be eligible for a 100% first-year deduction.

• CCA Class 44: Patents and intellectual property
• CCA Class 46: Data network infrastructure equipment and related systems
• CCA Class 50: General-purpose electronic data processing equipment (computer hardware) and systems software

Purpose-built residential rentals: The Government of Canada proposes to provide an accelerated CCA rate of 10% (up from 4%) for new eligible purpose-built residential rentals. These projects would have to begin construction after April 15, 2024, and before 2031, and the property must be available for use before 2036.

AS13 – Alberta AT1 Schedule 13: Capital Cost Allowance

All RIIP additions, where applicable, are incorporated in the CCA calculations and the ending UCC balances on AT1 Schedule 13. Alberta Finance has not yet released an updated version of the schedule to include separate RIIP columns. AT1 Schedule 13 will be updated in a future release when Alberta Finance releases the updated form.

Schedule 12 - Resource-Related Deductions

The 2024 Fall Economic Statement introduced two new reaccelerated expense categories — Reaccelerated Canadian Development Expenses (RCDE) and Reaccelerated Canadian Oil and Gas Property Expenses (RCOGPE) — for eligible expenses incurred after 2024. Schedule 12 has been updated to reflect these legislative changes.

On the CDE side, line 372 has been added to capture RCDE incurred during the tax year. Three new calculated amounts (AA, BB, and CC) now appear to support the revised current-year deduction at line 345, which incorporates a reaccelerated rate of 15%. The lines previously used to split ACDE between pre-2024 and post-2023 tax years have been removed as they are no longer applicable.

On the COGPE side, line 453 has been added for RCOGPE incurred during the tax year, along with three new calculated amounts (DD, EE, and FF) supporting the revised current-year deduction at line 445, now incorporating a reaccelerated rate of 5%. Similarly, the lines previously used for the ACOGPE pre-2024/post-2023 split have been removed.

Client files prepared in a previous version of ProTax will not retain amounts that were entered on any of the removed lines. Please review these sections before filing.

Schedule 21 - Federal and Provincial or Territorial Foreign Income Tax Credits and Federal Logging Tax Credit

The updated Schedule 21 introduces several changes to Parts 6, 7, and 8 to align with new tax regulations. In Part 6, a new line was added for the employer deduction for non-qualified securities (line 352), which expands the subtractions used to determine adjusted net income. Parts 7 and 8 have both been updated to explicitly specify additional tax on personal services business income (line 560) and to integrate a brand-new line for the total labour requirements addition to tax (line 580). Furthermore, Part 7 expands the scope of the refundable tax on investment income (line 604) to explicitly include substantive CCPCs alongside standard CCPCs.

Schedule 31 - Investment Tax Credit – Corporation

Budget 2025 introduced several significant changes to the SR&ED Investment Tax Credit program, and Schedule 31 has been updated to reflect all of them.

Expanded eligibility. New checkboxes have been added in Part 9 to identify Eligible Canadian Public Corporations (ECPCs) and CCPCs making an election under subsection 127(10.31) or (10.32). For tax years starting after December 15, 2024, ECPCs can now access the enhanced SR&ED credit — including the 35% enhanced rate up to the expenditure limit, and the basic rate of 15% on any qualified expenditures above the expenditure limit. The refundable credit in Part 15 has also been updated accordingly.

Updated phase-out calculation in Part 9. For tax years starting after December 15, 2024, the phase-out for ECPCs and electing CCPCs is no longer based on taxable capital. Instead, these corporations enter their average annual revenue minus $15 million at the new line 399 — the expenditure limit phases out once revenue exceeds $15 million and becomes nil at $75 million. Non-electing stand-alone CCPCs continue to use taxable capital at line 398. For tax years starting before December 16, 2024, Part 9 is unchanged.

Updated expenditure limit in Part 10. Part 10 has been split into two versions. Part 10A applies to tax years starting before December 16, 2024, and retains the previous $40 million phase-out with a maximum expenditure limit of $3 million. Part 10B applies to tax years starting after December 15, 2024, and reflects the new thresholds — the expenditure limit phases out between $15 million and $75 million in annual revenue, producing a maximum expenditure limit of $6 million. New calculation lines 10A through 10D support this updated formula.

Restored capital expenditures. A new line 360 has been added to Part 8 to capture capital expenditures incurred after December 15, 2024 (sourced from line 558 on Form T661). To apply the appropriate rates to these expenditures, new amounts 11C, 11D, and 11E have been added to Part 11. The total SR&ED ITC at line 473 now incorporates these additional amounts.

Other updates. The former Part 23 – Recapture of ITC for child care spaces has been removed. The ITC for child care space expenditures can no longer be claimed; only unused credits that have not yet expired may be carried forward. A new Part 23 – Clean economy ITCs has been added in its place, which includes line 185 for reporting the clean electricity ITC from Schedule 77. A new line 25C has been added to capture the recaptured or recovered clean hydrogen ITC from Schedule 74, and in Part 24, line 24E has been added for the recaptured or recovered clean electricity ITC. The Part 16 recapture totals have been updated accordingly.

Schedule 49 -  Agreement Among Associated Canadian-Controlled Private Corporations to Allocate the Expenditure Limit 

Schedule 49 has been updated to reflect several changes for tax years beginning after December 15, 2024. The expenditure limit has been increased from $3 million to $6 million, and the taxable capital phase-out threshold has been raised from $40 million to $60 million. The form title has also been revised to remove the "Canadian-Controlled Private" restriction, expanding eligibility to include public corporations.

Schedule 61, Agreement to Allocate Assistance for SR&ED Between Persons Not Dealing at Arm's Length – T1145

Following the reinstatement of SR&ED capital expenditures announced in Budget 2025, T1145 has been updated to capture a breakdown of the total allocated assistance.

Two new lines have been added under line 010. Line 015 is used to enter the portion of the allocated assistance relating to current expenditures, and line 020 is used to enter the portion relating to capital expenditures incurred after December 15, 2024. The transferee is now required to report these amounts on lines 538 and 540 of Form T661 respectively, replacing the previous instruction to report only on line 538.

The Authorization of Transfer section has also been updated with revised legal language around the filing requirements for directors' resolutions and authorized officers.

Schedule 62, Agreement to Transfer Qualified Expenditures Incurred in Respect of SR&ED Contracts Between Persons Not Dealing at Arm's Length – T1146

Following the reinstatement of SR&ED capital expenditures announced in Budget 2025, T1146 has been updated to capture a breakdown of the total transferred amount.

Two new lines have been added under line 010. Line 015 is used to enter the portion of the transferred amount relating to current expenditures, and line 020 is used to enter the portion relating to capital expenditures incurred after December 15, 2024. The transferee is now required to carry these amounts over to lines 508 and 510 of Form T661, and the transferor to lines 544 and 546 of Form T661, replacing the previous instruction to report only on lines 508 and 544.

The Authorization to Transfer section has also been updated with revised legal language around the filing requirements for directors' resolutions and authorized officers.

Schedule 75, Clean Technology Investment Tax Credit

Part 1 has been updated with a new column — line 105 — to enter a description of the clean technology property.

Part 2 has been updated with two new columns: line 210 for the province or territory in which the property is located, and line 212 for the available-for-use date of the property.

A new Part 5 – Amounts allocated from partnerships has been added for corporations that receive clean technology ITC allocations from one or more partnerships. The table captures the partnership name, account number, the clean technology ITC allocated (line 510), the ITC recapture allocated (line 515), and the labour requirements addition to tax allocated (line 520). The totals from Part 5 now flow automatically into line 160 and the applicable recapture lines in Part 3.

The filing instructions have also been updated — the deadline for filing this schedule is now the later of December 31, 2026, and one year after your filing-due date for the tax year in which the property became available for use.

Schedule 76 - Clean Technology Manufacturing Investment Tax Credit

Schedule 76 has been updated with several additions. In Part 1, the method for identifying eligible CTM property has changed: rather than entering a description of how the asset is used, you now enter the CTM asset code (line 106) to classify the property type. Additionally, Part 2 now includes a new note regarding the treatment of CTM property that is disposed of to a related taxable Canadian corporation, providing guidance on how the ITC is affected in these scenarios.

A new section has been added to support allocations from partnerships. Amounts of the Clean Technology Manufacturing ITC allocated from a partnership can now be entered directly on Schedule 76 and will be included in the total ITC calculation.

Schedule 78 – Carbon Capture, Utilization, and Storage (CCUS) Investment Tax Credit

Schedule 78 has been updated to reflect legislative changes to the CCUS Investment Tax Credit program. In Part 1, the credit rate table has been updated: the first rate period now runs from after 2021 to before 2036 (previously before 2031), and the second rate period runs from after 2035 to before 2041 (previously after 2030). This extension means the full applicable rate applies for an additional five years.

In Part 3, the prevailing wage attestation section has been expanded to clarify that once the election is made, it cannot be revoked under the Income Tax Act. The attestation wording now also notes that the corporation is expected to maintain supporting documentation, and that failure to provide it to the CRA upon request may result in a gross negligence penalty under subsection 127.46(9).

A new Part 5 – Amounts Allocated from Partnerships has been added. This table allows corporations to separately identify partnership-allocated CCUS ITC amounts, labour requirements additions to tax, and Part XII.7 tax received from partnerships (lines 500 to 520), referencing the corresponding boxes from the T5013 slip.

Schedule 200 – T2 Corporation Income Tax Return

The T2 Corporation Income Tax Return has been updated for 2025 and later tax years. Schedule 65 – Air Quality Improvement Tax Credit has been removed from the T2 return. Line 275 (the question asking whether the corporation is claiming this credit) and line 799 (the credit amount) are no longer available on the return. The Air Quality Improvement Tax Credit was a temporary measure for qualifying expenditures made to improve air quality in commercial spaces; as this credit has expired, the schedule is no longer supported. Additionally, line 315 (gifts of medicine made before March 22, 2017) has been removed from the deductions section of the return as this item is no longer applicable. 

SK S403 – Saskatchewan Research and Development Tax Credit 

As a result of the Budget 2025 changes to the SR&ED expenditure limit on Schedule 31 — which increased from $3,000,000 to $6,000,000 retroactive to January 1, 2025 — the qualifying SR&ED expenditure ceiling used in Schedule 403 Part 4 has effectively doubled, from $1,000,000 to $2,000,000, effective retroactive to December 16, 2024.

The software has been updated to correctly calculate the Saskatchewan R&D credit using the new, higher expenditure limit from Schedule 31. Corporations that had SR&ED qualifying expenditures in prior years back to January 1, 2025 may wish to review their filings to assess the impact of this retroactive change.

Schedule 500 - Ontario Corporation Tax Calculation

Ontario's small business deduction (SBD) rate is increasing from 8.3% to 9.3% effective July 1, 2026. Schedule 500 has been updated to support a prorated calculation of the Ontario SBD for tax years that straddle the July 1, 2026 effective date. The software will automatically calculate the blended rate based on the number of days in the taxation year before and after the rate change.

Schedule 572 – Ontario Made Manufacturing Investment Tax Credit (OMMITC) – 2025 and Later Tax Years

Enacted under Bill 68 on November 27, 2025, Schedule 572 has been significantly expanded for the 2025 and later tax years to extend the OMMITC program to non-Canadian-controlled private corporations (non-CCPCs) at a 15% rate, introducing a new 10-year carryforward schedule for their unused non-refundable credits. For CCPCs, the eligible property section now implements a tiered credit rate—10% for property available before May 15, 2025, and 15% thereafter—while expanding qualifying capital assets to include CCA Class 43(a) alongside Classes 1 and 53. The updated form also integrates a brand-new Line 421 on Schedule 5 to map non-refundable credits directly against Ontario corporate income tax payable, and features a new repayment provision reconciliation section for previous claimants that automatically flows its summary implications into Schedule 5.

T661 – Scientific Research and Experimental Development (SR&ED) Expenditures Claim

Budget 2025 introduced significant changes to the SR&ED investment tax credit program, and Form T661 has been updated accordingly. In Part 3, new fields have been added to identify and track depreciable property acquired after December 15, 2024 that was used for SR&ED activities, including the property name, capital expenditure amount, and a listing of project numbers in which the property was used. Part 4 has similarly been updated to capture additional capital cost information for SR&ED-related property.

Part 6 now includes new expanding tables to support the transferor (T1146) and transferee (T1145) scenarios, allowing corporations that have transferred or received qualified SR&ED expenditures to detail those amounts directly on the T661. Schedule 60 (T661 Part 2 – Project Information) has also been updated with new fields to capture capital expenditure details at the project level, including information on depreciable property used in individual SR&ED projects.

AS12 – Alberta Schedule 12: Income/Loss Reconciliation

AS12 has been updated to accommodate the treatment of Restricted Interest and Financing Expenses (RIFE) and employer deductions for non-qualified securities for Alberta purposes. Four new fields have been added: line 131 captures the Federal RIFE amount (linked from T2 line 336), and line 130 captures the Alberta RIFE amount (linked from Schedule 21, line 240), recognizing that the Alberta and Federal amounts may differ. Similarly, line 141 captures the Federal employer deduction for non-qualified securities (from T2 line 352), and line 140 captures the Alberta amount. These additions ensure the Alberta taxable income reconciliation properly reflects any differences between federal and provincial treatment of these items. 

AS21 – Alberta Schedule 21: Loss Continuity and Application

AS21 has been updated to incorporate the treatment of Restricted Interest and Financing Expenses (RIFE) and employer deductions for non-qualified securities within the loss continuity calculation.

A new RIFE section has been added to the Non-Capital Loss continuity. Line 002 captures the RIFE deducted for the tax year under paragraph 111(1)(a.1) of the Income Tax Act, and line 012 captures the employer deduction for non-qualified securities under paragraph 110(1)(e). These amounts are included in the subtotal of deductions (lines 002 to 012) when calculating the closing non-capital loss balance. The schedule now also clarifies that the Capital Losses column reflects gross amounts.

The updated form also includes revised instructions noting that if the Alberta RIFE balances differ from federal amounts, the Alberta-specific amounts should be entered. 

SCT1 – Saskatchewan Corporation Capital Tax Return

The Saskatchewan Corporation Capital Tax Return has been updated to reflect two significant changes from the Saskatchewan Budget.

First, the Goodwill Allowance (line 550 – Schedule B, Part 2) has been removed from the form entirely, along with all sections and cross-references that previously depended on it. The Investment Allowance summary table and Schedule D calculations have been updated to reflect this removal.

Second, effective April 1, 2026, Saskatchewan has updated its Corporation Capital Tax (CCT) rates: the CCT rate for large financial institutions increases from 4% to 6%, the CCT for small financial institutions has been eliminated, and the CCT rate for commercial Crown corporations is reduced from 0.6% to 0.3%. The software now automatically calculates the blended rate for tax years that straddle the April 1, 2026 effective date. 

T25QCC – Joint Election for Capital Gains Deduction in Respect of a Qualifying Cooperative Conversion (New!)

T25QCC is a new form for the 2025 and later tax years. It is used by a worker cooperative (WC) to jointly elect with all individuals who disposed of shares of a subject corporation under a qualifying cooperative conversion (QCC), as described under subsection 110.62(1). The form serves as the joint election required for those individuals to claim the capital gains deduction determined under subsection 110.62(2), and includes sections for identification, election details, subject shares and disposition details, the penalty calculation for late-filed elections, and election certification. 

AExempt – Alberta Exemption (AT100)

A new option has been added to the AT100 form: "File even if exempt from filing AT1?" This allows corporations that otherwise meet the Alberta filing exemption criteria to override the exemption and transmit their AT1 via NetFile. Previously, ProTax would prevent AT1 transmission for exempt corporations; this new option gives preparers the ability to file when they determine it is appropriate to do so despite the exemption.

FX - Forms

GST190 - GST/HST New Housing Rebate Application for Houses Purchased from a Builder 

Form GST190 is filed by an individual who bought a newly built (or substantially renovated) home or share in a co-op from a builder and is claiming a GST/HST rebate. The form already covered the New Housing Rebate (NHR) and has now been updated to add the new first-time home buyers' (FTHB) GST/HST rebate (capped at $50,000). It now also includes X1 / X2 deduction fields on each section's "Total" line so the claimant can subtract any GST/HST or provincial new housing rebate already claimed for the same house.

GST190WS - GST190 Calculation Worksheet 

The GST190-WS (GST190 Calculation Worksheet) has been restructured from 3 parts to 6 sections to support the new first-time home buyers' (FTHB) GST/HST rebate (capped at $50,000). Sections 1–3 retain the existing GST/HST New Housing Rebate (NHR) calculations; new Sections 4–6 add the FTHB rebate calculations for each application type (1A/2, 1B/5, and Type 3). New routing instructions at the top of the form direct claimants to the appropriate section based on their rebate type and application type. 

GST191 - GST/HST New Housing Rebate Application for Owner-Build Houses

The form has been updated to add the claim for the first-time home buyers' (FTHB) GST/HST rebate. It is filed by an individual who built (or substantially renovated) their own home and is claiming a GST/HST rebate on materials and services. With the 2025 changes, the claimant now has two possible rebates to consider on the same form:

• GST/HST New Housing Rebate (NHR) — the long-standing 36% rebate of the federal GST/HST paid, capped at $6,300, available when the home's fair market value (FMV) at substantial completion is under $450,000.
• First-time Home Buyers' (FTHB) GST/HST Rebate — the new rebate, up to $50,000, available when this is the claimant's first home and FMV is under $1,500,000. Claimants may take it instead of, or in addition to, the NHR.

The new lines X1 and X2 let the claimant subtract any GST/HST or provincial new housing rebate they have already claimed elsewhere for the same house.

GST191WS - Construction Summary Worksheet

The new form removed the obsolete sales tax columns in Part C:

• GST paid at 6%
• GST paid at 7%
• HST paid at 12%
• HST paid at 14% before 2008
• HST paid at 15% before 2007

The available sales tax columns are now grouped into the same table:

• GST paid at 5%
• HST paid at 13%
• HST paid at 14%
• HST paid at 15%

Fixed issue with AIIP/RIIP audit incorrectly triggering

We’ve fixed an issue where following the update to Version 2026.3.1, some T1 2025 users may have encountered auditor warning messages on Asset forms requesting to confirm if an asset addition in the year was AIIP or RIIP even when the form wasn't in use or contained no asset additions for the year.

This was happening upon opening files that were created prior to the 2026.3.1 release.

This update helps make sure that customers are only prompted when there has been an addition in the year and both the AIIP and RIIP indicators have been selected for that specific addition.

Bill C-15 changes to accelerated CCA and immediate expensing

The self-employment and rental schedules T2125CCA, T2042CCA, T2121CCA, T1163-T1273CCA, T776CCA , and  ResourceCCA are updated to reflect the measures introduced in Bill C-15. The Bill reinstates the accelerated investment incentive, now called the reaccelerated investment incentive (RIIP). It also reinstates immediate expensing for certain capital cost allowance (CCA) classes. The RIIP and immediate expensing allows qualifying property acquired on or after January 1, 2025 and available for use before 2030. The measure would be phased out starting in 2030, and fully eliminated after 2033. 

Productivity-enhancing assets:

An additional enhanced first-year allowance for new additions of property to CCA Classes 44, 46, and 50 acquired after April 15, 2024, and available for use before January 1, 2027. These additions would be eligible for a 100% first-year deduction.

• CCA Class 44: Patents and intellectual property
• CCA Class 46: Data network infrastructure equipment and related systems
• CCA Class 50: General-purpose electronic data processing equipment (computer hardware) and systems software

Purpose-built residential rentals

The Government of Canada proposes to provide an accelerated CCA rate of 10% (up from 4%) for new eligible purpose-built residential rentals. These projects would have to begin construction after April 15, 2024, and before 2031, and the property be available for use before 2036.

These updates show the final versions provided by the CRA. However, the Bill C-15 measures are still proposed legislation that is being reviewed by parliament.

If you entered data or added new assets in a previous release, we recommend revisiting these forms to verify that any qualifying property is correctly identified to trigger the new accelerated investment rules and 100% immediate expensing where applicable.

Revised T777 CCA table

The CRA released a new version of the T777, Statement of Employment Expenses, on February 26th with an updated CCA table to incorporate the proposed reaccelerated investment incentive property (RIIP) measures introduced in Bill C-15. The CCA calculations now reflect the new measures.

We recommend that users who previously entered employment expenses review their CCA claims to ensure the new calculations are applied correctly before filing. This ensures that any qualifying assets receive the correct accelerated treatment. 

GST/HST credit is now the Canada Groceries and Essentials Benefit (CGEB) (New!)

The GST/HST credit worksheet (GST) is renamed the Canada Groceries and Essentials Benefit (CGEB). The estimated benefit is updated to reflect a 25% increase to the July 2026-June 2027 payment period. 

A paragraph has been added to the Letter template to inform individuals that they may be eligible for an extra 50% top-up payment if they received the GST/HST credit in the previous year. The extra payment will be paid by June 2026.

T2 - Corporate Taxes

Cantax, Taxprep, and DT Max to ProTax carry forward

These updates show the final versions provided by the CRA. However, the Bill C-15 measures are still proposed legislation that is being reviewed by parliament.

If you entered data or added new assets in a previous release, we recommend revisiting these forms to verify that any qualifying property is correctly identified to trigger the new accelerated investment rules and 100% immediate expensing where applicable.

T1 - Personal Taxes

Bill C-15 proposed changes to accelerated CCA and immediate expensing

On November 18, 2025, the federal government tabled Bill C-15, which includes several measures related to accelerated capital cost allowance (CCA) and other immediate expensing measures. These include a temporary measure to reintroduce the accelerated investment incentive (referred to as reaccelerated investment incentive property or RIIP), and allow taxpayers to claim accelerated first-year CCA deductions, enhanced CCA for purpose-built rental housing and immediate expensing for:

• Manufacturing and processing (M&P) machinery and equipment
• Clean energy equipment
• Zero-emission vehicles
• Productivity-enhancing assets

We're currently updating our self-employment and rental schedules to reflect these proposed measures. As a result, the following forms ‌will have the banner "This form is currently under review" for this release: T2125CCA, T2042CCA, T2121CCA, T1163-T1273CCA, T776CCA, and ResourceCCA. You may still enter data into these forms; however, the final version with finalized CCA calculations will be available in our next release

Changes to Viewing Notice of Assessments in Tax software

As of February 9, 2025, the CRA decommissioned the ability to deliver notice of assessments (NOA) and reassessment (NORA) in the Tax Software products for all future and prior tax years.

If you attempt to access an NOA or NORA using our older modules (2024 and prior) an error will be returned.

The assessments will only be available to view exclusively on the Canada Revenue Agency (CRA) portals (My Account, My Business Account, and Represent a Client). The CRA will send an email after they've received and processed the tax return. For individuals who don't have a CRA account, or have chosen to receive correspondence by mail, the CRA will send notices to the mailing address on file.

For more information on how to receive the notices of assessment and reassessment please visit this CRA website.

CRA Efile Security Enhancement

The CRA is now implementing a mandatory security process that links your EFILE account to specific certified T1 and T3 software products. This improvement makes submissions safer by making sure returns are only sent through the software associated with your EFILE account.

For the current filing season, the CRA has automatically associated your EFILE account with this software based on your historical usage. However, if you attempt to submit a T1 or T3 return using a product not currently linked to your account, the transmission will fail and the return will be rejected.

If you need to update your software preferences or confirm if ProTax is linked to your account, please contact your CRA EFILE helpdesk immediately to ensure uninterrupted filing

Mandatory EFLE Hard Block on certain errors

We have integrated mandatory EFILE validation blocks as required by the Canada Revenue Agency (CRA). These blocks are designed to prevent the submission of returns that contain critical formatting errors or missing mandatory fields that'd result in an automatic rejection by the CRA’s systems. These errors will be listed specifically as CRA EFILE Blocking Error within the Auditor. Users must resolve all such errors before the software will permit the electronic transmission of the return. For more info, check out this article.

Non-resident tax returns

Returns for emigrants, deemed residents (Section 250) (excluding deemed residents of Quebec) and for non-residents filing under section 116 are now EFILE-certified for the 2025 tax year.

Tax rate change

The lowest marginal individual income tax rate has been adjusted for 2025. Effective July 1, 2025, the rate decreases from 15% to 14%. Because this change is implemented mid-year, the effective full-year lowest marginal individual income tax rate for 2025 will be 14.5%. Importantly, the rate used for most non-refundable tax credits remains tied to the lowest marginal individual income tax rate for the year.

Top-up tax credit

For the 2025 tax year, a new non-refundable tax credit is available to individuals at line 34990. This credit is designed to maintain an effective 15-% rate for certain non-refundable tax credits claimed on income amounts exceeding the first income tax bracket threshold, which is $57,375 for 2025. Individuals can claim this credit if they are claiming specific non-refundable tax credits that are impacted by the reduction of the lowest marginal individual income tax rate from 15% to 14.5% for 2025.

T657 - Calculation of Capital Gains Deduction

Capital gains deduction calculations for Qualifying Business Transfers or Qualifying Cooperative Conversions on T2048 are being adjusted for the following calculations on T657:

• Line 21 - Annual gains limit for 2025 in Step 1;
• Line 19 - Cumulative gains limit for 2025 in Step 2;
• Capital gains deduction calculation charts after 2023.

There's a new Chart 2025 - Part 1 available for capital gains deduction calculations for  the qualified farm or fishing property (QFFP) and qualified small business corporation shares (QSBCS) reported on a 2025 T3 or T5013 slip for a disposition that took place in Period 1 of 2024. The maximum capital gains deduction for such QFFP and/or QSBCS dispositions is $522,145. 

T2017 - Summary of Reserves on Dispositions of Capital Property

Reserves from dispositions of qualifying business transfers (QBT) or qualifying cooperative conversions (QCC) after 2023 are now included in the reserve calculations on T2017.

The calculations for reserves on dispositions of capital property before June 25, 2024 are now removed. 

T2 - Corporate Taxes

AGRI - T2 AgriStability and AgriInvest 

AgriStability forms are updated to support 2025 tax year filings.

S8 - Capital Cost Allowance

To reflect annual regulatory updates for Schedule 8, the Capital Cost Allowance (CCA) ceiling for Class 10.1 passenger vehicles has been increased from $38,000 to $39,000 before tax for all acquisitions made on or after January 1, 2026.

Bill C-15

On November 4, 2025, the Canadian federal government tabled Bill C-15, which reinstates the accelerated investment incentive, now called reaccelerated investment incentive (RII), and immediate expensing of manufacturing and processing machinery and equipment, clean energy equipment, and zero-emission vehicles. The RII and immediate expensing would be available for qualifying property acquired on or after January 1, 2025, and that becomes available for use before 2034, with a four-year phase-out for property that becomes available for use after 2029.

The CRA has communicated to us that these changes can now be taken into account when preparing returns. They will publish a revised Schedule 8 to support these changes at a future date, which we'll include in our software when made available. Until then, you can manually override the CCA amounts for 2025 and 2026 acquisitions eligible under Bill C-15.

S63 - Return of Fuel Charge Proceeds to Farmers Tax Credit

To reflect the conclusion of the federal fuel charge on April 1, 2025, a new notice validation is added to Schedule 63 regarding the Return of Fuel Charge Proceeds to Farmers Tax Credit. This validation informs users that the 2024–2025 period represents the final credit for eligible claimants, as the Minister of Finance has officially set a nil payment rate per $1,000 of eligible farming expenses incurred during the 2025-calendar year across all designated provinces.
