Make VAT adjustments in QuickBooks

by Intuit•28• Updated 2 weeks ago

Learn how to make VAT adjustments in QuickBooks Online, what happens after an adjustment is made, and how to correct errors in previously filed returns.

Note: If you make changes to your return, it will affect your VAT control and/or VAT suspense account. Before making any changes, we recommend speaking to an accountant to understand the process.

How to adjust VAT in QuickBooks

  • You can adjust your current VAT account to correct errors on past returns with a VAT account adjustment if they're below the reporting threshold, not deliberate, and less than 4 years old.
  • You must report any errors that do not meet the above conditions to HMRC.
  • When you submit your next return, make sure you add the net value to Box 1 for tax any due to HMRC, or to Box 4 for tax owed to you.
  • Keep details about any inaccuracies on your return. For example, the date it was discovered, how it happened, the amount of VAT involved and so on.
  • Remember, any inaccuracies must be accounted for in your VAT account.
  1. Go to Taxes, and select VAT (Take me there).
  2. Next to the period you're submitting for, select Prepare return.
  3. Next to the VAT line you'd like to change, select Adjust.
  4. Choose an Adjustment Date and Tax rate.
    • Note: If you don't select the right VAT code, it won't appear on reports or your tax return.
  5. Select Adjustment Account ▼.
  6. Choose an account.
    • If you're making an adjustment because you received credit and owe less tax to the government, choose an income account you created for this purpose.
    • If you're making the adjustment to include a fine, penalty, or interest on a VAT return, choose an expense account, such as Interest Expense or Non-deductible Penalties.
  7. In the Adjustment amount section, enter the amount of the adjustment.
  8. Enter a Memo to describe the adjustment. It's good practice to include this, since it will help identify the adjustment.
  9. Select Save.

If you're on Flat Rate VAT, you can't change these boxes. Talk to your accountant for help.

  1. Go to Taxes, and select VAT (Take me there).
  2. Select Prepare return for the period you are submitting for.
  3. Next to the VAT line that you want to change, select Adjust.
  4. In the Adjustment amount section, enter the amount of the adjustment.
  5. Enter a Memo to describe the adjustment. It's good practice to include this, since it will help identify the adjustment.
  6. Select Save.

QuickBooks will create a journal for you. You can find them in the audit log or search for them. They're posted as soon as they're created. Here's what happens for each box when you create an adjustment:

Adding an adjustment to box 6 will create a credit and debit to your VAT suspense account. This will have a VAT code of Exempt (Sales), so it'll impact the net value of sales.

Adding an adjustment to box 7 will create a debit and credit to your VAT suspense. This will have a default VAT code of Exempt (Purchases) and only impact the net value of purchases.

Adding an adjustment to box 8 will create a credit to your VAT suspense account. This will have default VAT code of 0.0% ECG (Sales), and debit to the VAT suspense account with default VAT code of 0.0% Z (Sales).

Adding an adjustment to box 9 will create a debit to your VAT suspense account with a default VAT code of 0.0% ECG (Purchases), and credit to the VAT suspense account with default VAT code of 0.0% Z (Purchases).

What happens after I make an adjustment?

QuickBooks makes an journal entry to show the adjustment, and the adjustment will show in the next VAT return you submit to HMRC. The adjustment amount is on your return against the box you adjusted.

The adjustment is shown as a journal entry under the related section of the VAT Detail Report.


What happens if I've already submitted my VAT return?

You can't change or undo a VAT return after it's been submitted through Making Tax Digital (MTD). You need to take into account any changes from the previous period to the current period.

If you have already submitted the VAT return in QuickBooks but need to make changes, help is available from the support team.


Reporting errors in previously filed VAT returns (VAT652)

If you find a VAT error after submitting a return, you may need to notify HMRC by completing form VAT652. Whether you report it to HMRC or adjust it in your next return depends on the nature and size of the error.

You must report the error using form VAT652 if:

  • The net value of the error is more than £10,000, or
  • The error is more than 1% of your Box 6 figure for the period of discovery (with a cap of £50,000), or
  • The error was deliberate or relates to fraud, regardless of value, or
  • It occurred more than 4 years ago

These errors can’t be corrected within QuickBooks and must be disclosed to HMRC directly.

You can adjust the VAT return in QuickBooks without contacting HMRC if:

  • The error is less than £10,000, and
  • Less than 1% of the Box 6 figure, and
  • Not deliberate or fraudulent, and
  • It occurred within the past 4 years

Add the adjustment in QuickBooks and keep clear records showing:

  • The date the error was discovered
  • The VAT period it relates to
  • The nature and cause of the error
  • The adjustment amount
  • Tick Adjusted in VAT return if you’ve already included the correction in a return.
  • Round refunds up and payments down to the nearest pound.
  • Split input and output VAT errors:
    • Use “1” for input tax errors
    • Use “0” for output tax errors
    • Keep supporting evidence, as HMRC may ask for additional detail.
