Attention begins.
If you need to edit details you have submitted on Incomes Register reports, do it on 6 March 2026 at the latest. This way, we receive the corrections in time for the wage earners’ pre-completed tax returns.
You can ask the Incomes Register to send you “payer’s transcripts”. You can use them to reconcile and re-check all the payroll information that you submitted: Summary of payer’s earnings payment data (630), and Income type specific summary of payer’s earnings payment reports (618).
If your corrections have to do with individuals’ income information, also re-check the occupational class as recorded, along with the individual’s insurance information. If problems are detected, you can deal with all of them at this time.
Attention ends
If you notice an error in the earnings payment data you have submitted to the Incomes Register, correct the data in the Incomes Register. You cannot correct it in MyTax.
Whenever you notice an error, please correct it as soon as possible. Responsibility for correcting errors lies with the employer or other payor.
Income earners who notice errors in their data must ask the payor to correct them.
This also applies to pension and benefits income paid by organisations such as pension providers, insurance companies, Kela, the State Treasury, and municipalities.
Correct errors by submitting a new report to the Incomes Register. The new report will replace your original report. Note that the replacement report must be complete: you must enter the details that were correct in the original report, as well as any new and changed details.
Correct all data, both mandatory and complementary. Also enter any necessary details that were missing from the original report.
Example: The income data on the previously submitted earnings payment report changes in such a way that the amount of the employer’s health insurance contribution also changes. Correct the earnings payment report and also file a new employer's separate report with a corrected total amount of the health insurance contribution.
In some circumstances, however, you must make the correction by first cancelling the erroneous report and then submitting a new report.
If you need to cancel any reports you have submitted to the Incomes Register, first cancel the erroneous report and then submit a new report during the same day.
To safeguard monthly payments to tax recipients, please avoid cancelling reports on the 15th–20th of the calendar month. If you must do so, however, it is vital that you replace the cancelled report with a new report immediately after the cancellation.

When you cancel a report, the details of the report are removed from the Incomes Register and you can no longer allocate corrections or any other changes to the report. If you need to replace the cancelled report with an entirely new report, the new report’s data will not be allocated to the cancelled report.
A late-filing penalty will be imposed on new reports if you cancel reports and file replacement reports for them after more than 45 days since the 8th day of the month following the payment date. (If the 8th day of the month falls on a Saturday, Sunday or a public holiday, the counting of the 45-day period begins the day after the next business day.)
However, no late-filing penalty will be imposed if the new report does not contain additional taxable payments or work income on which the pension is based and if you:

If you correct a report submitted to the Incomes Register by cancelling it and do not submit a replacement report during the same day, the payment you have previously made to the Tax Administration may be returned. The payment may be returned to the payor if the amount of tax to be paid for the tax period decreases because of the cancellation of the report.
If you do not submit a replacement for the cancelled report until later, the tax imposed will be shown in MyTax as unpaid. Late-payment interest will accrue on any unpaid tax starting from the original due date of the tax.
If you paid the tax on time but late-payment interest accrues on the tax because the report has been cancelled, you can request non-collection of interest in MyTax.
You can make corrections to the data submitted to the Incomes Register for as long as the data is stored in the Incomes Register. The incomes information system stores the data for 10 years. The 10-year period is counted from the beginning of the year following the year when the data was first saved.
Please note, however, that tax assessment can be adjusted only within 3 years from the accounting year that includes the tax period for which the tax should have been filed and paid. The 3-year period is counted from the beginning of the year following the end of the accounting year.
