When printing T4, the year is correct on T4, but the amounts were for the year before last year.

You haven't run the payroll year-end to move the earnings to the Last Year column.

Follow these steps to check and correct the issue. For easy illustration, we assume that this year is 2025, last year is 2024, and the prior year is 2023.

If the Last Year column has the correct amounts (for 2024)

1. Open the payroll module and select an employee.
2. Click Earnings tab. Check the amounts under the Last Year column. 
3. T4 gets the information from the Last Year column. 
4. If the Last Year shows 2023 amounts, you haven't run the payroll year-end process. 
5. Check the amounts in This Year column, and continue with the next step.

This Year column contains the amounts for Last Year (2024), and you haven't entered any paycheques for 2025

1. Make a backup of data.
2. Sign in the company with the December 31 of last year (12/31/24). 
3. Perform payroll year-end.
4. Confirm that Last Year has the correct amounts for last year (2024).
5. This Year column must be empty.
6. Log in with January 1 of the current year (01/01/2025) and print T4 again.

The amounts under This Year column are too high for last year 2024

In this case, you’ve entered the payroll for the current year (2025). The earnings of 2025 combined with the earnings of 2024.

1. Make a backup of the current data.
2. Print the report of all paycheques for the current year (2025).
3. Void all the paycheques for the current year (2025).
4. Check the Earnings tab. Confirm This Year column has the correct amounts for last year (2024).
5. Make another backup of data.
6. Sign in with December 31 of last year (12/31/24).
7. Perform payroll year-end to move the amounts under This Year column to the Last Year column. Confirm the Last Year column has the correct amount (2024).
8. Sign in January 1 of the current year (01/01/25) and print T4. Confirm that T4 has the correct amounts.
9. Re-enter all the paycheques for the current year (2025) that you voided in step 3.
