What is a TD1 form?

The TD1 form (also known as the Personal Tax Credits Return) determines the amount of federal and provincial or territorial income tax to withhold from an individual’s earnings. The form accounts for personal tax credits, which reduce taxable income. These include basic income exemptions, caregiving credits, and tuition fees.

Businesses use the TD1 form to calculate the proper amount of income tax to deduct from their employees’ paycheques. It’s also a vital tool for companies providing pensions, helping them manage tax deductions for retiring employees.

Why is the TD1 form important?

The TD1 form plays a critical role in accurate tax management for both employees and employers.

Here’s an overview of the benefits that TD1 forms provide for both parties: 

For employees

• Ensures the correct amount of tax is withheld at the source. This prevents any surprises at tax time.
• Reflects personal circumstances — such as dependents or disabilities — that may lower taxable income.
• It enables individuals to ask for additional deductions if needed. Doing so may help to better manage income and the potential taxes owed.

For employers

• Helps to comply with the Canada Revenue Agency (CRA) regulations by ensuring payroll deductions match federal and provincial tax requirements.
• Simplifies the onboarding process by clarifying the amount of tax to be deducted from each employee’s paycheque.
• Lowers the risk of penalties related to incorrect tax withholding.

Who should fill out the TD1 forms?

Employees need to complete a TD1 form in the following situations:

• Starting a new job: Employers must collect a TD1 form during the onboarding process.
• Beginning a pension: Individuals starting to receive pension payments need to fill out a TD1 form to determine tax deductions.
• Changing personal tax credits: Life milestones such as getting married, having children, or developing a disability may affect tax credits and require an updated TD1 form.
• Requesting additional tax deductions: Employees can withhold extra tax at the source to minimize the amount they may owe during tax season.
• Living in a prescribed zone: Some remote or northern residents may be eligible for additional tax credits.

How to distribute the TD1 form to employees

Employers are required to provide either print out and distribute the form, or provide their employees with the link to the Government of Canada website so they can fill it out remotely. Both the federal and provincial or territorial versions of the form can be found online.

Once signed, they must send it back to you online or provide you with a printed copy. Employees are required to submit these forms when they start working, and can resubmit whenever they need to update their tax credit claims.

Federal vs. provincial TD1 forms

There are two types of TD1 forms:

1. Federal TD1 form. The key form employees use across Canada (except in Quebec). It focuses on nationwide tax credits and deductions, such as the basic personal amount and the caregiving amounts.
2. Provincial/Territorial TD1 form. This form estimates the regional tax credits and tax deductions from the province or territory where the employee resides. 

Employees must fill out both forms and submit them to their employer when they start a new job. For example, Ontario residents should fill out a TD1ON form, British Columbia residents need to fill out the TD1BC form, and employees in Quebec must complete the TP-1015.3-V form.

Special TD1 Forms

In addition to the standard TD1 form, there are other special versions of the form you should be aware of:

• TD1-WS. This supplementary worksheet helps employees provide more specific financial information to calculate tax deductions. It’s used in conjunction with the TD1 form when an individual is claiming additional deductions or credits.
• TD1X. This form is for employees who earn commissions and would like additional tax deductions. This may be helpful for those who anticipate a
• higher income and may owe more taxes while filing their tax return.
• TD1-IN. Indigenous people registered under the Indian Act can use this form to determine if their income is tax exempt.

Be sure to download the correct version based on an employee’s location and the relevant deductions they wish to claim. 

How to fill out a TD1 form

Filling out the TD1 form for the first time may be daunting for your employees. Here’s a step-by-step guide you can share with your new hires.

Step 1: Enter your personal information

Start by providing your personal details, including your full name, date of birth, employee number, address, and Social Insurance Number (SIN). Non-residents will need to state their country of permanent residence. 

Step 2: Claim your tax credits

In the next section, you’ll see boxes to claim non-refundable tax credits.

Here are some common examples of tax credits you can claim:

Note: When it comes to BPA reduction, employees with net income over $181,440, the federal BPA gradually reduces, bottoming out at $14,829 for those earning $258,482 or more. High-income employees must check the "Net Income" box to avoid owing taxes at the end of the year.

Step 3: Add up your credits

After filling out the appropriate sections, add the amounts in the boxes. Then, enter the sum in the last box. This total number represents your total personal tax credits.

Step 4: Address unique circumstances

On the second page, you’ll need to indicate whether: 

• You have multiple employers or pension sources. 
• Your total income will be less than your total personal tax credits.

Step 5: Submit the form 

Return the completed TD1 form to your employer or pension provider. Remember that you don’t need to send the form to the CRA.

After you receive the TD1 forms

Here’s what you need to do once your employees have submitted their forms to you:

Step 1. Double-check the form to see if the employee has included any additional information, such as requesting additional tax to be deducted from their paycheque. 

Step 2. Take the total claim amount to determine the correct amount of federal and provincial or territorial income tax deductions.

Step 3. File these forms with each employee’s records. You do not need to send a copy to the CRA. 

Step 4. Figure out which tax tables to use.

Step 5. Calculate the deductions and remit them by the due date. 

Common misconceptions about TD1 forms

Myth: The TD1 form must be submitted to the CRA.

Truth: The completed form is submitted to the employer—not the CRA. Employers use it to add up the tax deductions from an employee's pay.

Myth: The TD1 form calculates how much tax you owe.

Truth: The form helps estimate tax deductions. However, the actual tax owed is calculated when you file your tax return—not solely based on the TD1.

Myth: The TD1 form only needs to be filled out once.

Truth: Employees need to update their TD1 form if their personal situation changes, such as having new dependents or needing to modify their tax credits.

Myth: Only full-time employees need a TD1 form.

Truth: All employees, including part-time, full-time, temporary workers, and pensioners, must complete the TD1 form.

By clearing up these misconceptions, employers and employees can go through the TD1 form process more efficiently and avoid potential errors or unnecessary penalties.

If an employee makes a mistake on a TD1 form

Mistakes on a TD1 form may lead to incorrect tax withholding. If an error is discovered, employees should complete a new TD1 form with the correct information, and submit it to their employer as soon as possible. Employers should promptly update their payroll after receiving the form in order to reflect the changes.

Penalties for employees who don’t submit a TD1 form

Employees who do not provide a completed TD1 form to their employer within 7 days of starting a new job or pension may face penalties from the CRA. 

These penalties range from a minimum penalty of $100, which increases to $25 per day, to a maximum fine of $2,500. To mitigate these issues, employers should incorporate the TD1 form into their onboarding process.

Tips for employers managing TD1 forms

Here are a few best practices for business owners to effectively manage their TD1 forms:

• Standardize the process. Include TD1 forms in your onboarding checklist for all new hires.
• Submit updates. Remind employees to update their forms if their tax credits change. This should be done within 7 days of a change to an individual’s situation.
• Use technology. Leverage payroll solutions to automatically manage deductions and store completed forms securely.
• Provide guidance. Inform employees on how to fill out their TD1 forms properly and answer any questions they may have.

Helping your employees manage tax deductions

The TD1 form is an essential document for ensuring precise tax deductions. This prevents employees and employers from experiencing tax-related issues down the road.
