How to make corrections to an annual information return

If you filed an annual information return that contains an error, make a correction as soon as possible. If the error is not corrected, the pre-completed details on individual tax returns will also be incorrect.

Please note that if you need to make corrections to earnings payment data submitted to the Incomes Register as of 1 January 2019, you must send the corrections to the Incomes Register.

Correction deadlines

Remember the following deadlines when filing corrections electronically to annual information returns for 2019:

  • If you make your corrections by 16 March 2020, they can be included on individual taxpayers’ pre-completed tax returns (if you file corrections on paper, the paper form must arrive at the Tax Administration by 15 March).
  • If you make your corrections by 30 April 2020, they can be included on individual taxpayers’ tax decisions even if they cannot be included on the pre-completed tax returns.

If you make corrections after 30 April 2020, the corrections will still be taken into account in tax assessment. If necessary, the taxes of the individuals concerned will be reassessed and their tax decisions will be adjusted.

Make corrections to annual information returns by filing a replacement return

File a replacement return only for the beneficiaries of income or other taxpayers whose information on the original return contained errors or omissions. The new itemisation replaces the information you had given on the previous itemisation. You must include all the required information concerning the beneficiaries: the new corrections as well as the details that were already correct. Include the taxpayer’s information for the entire calendar year.

If you are making corrections that concern an employer’s annual information for the year 2018 or earlier, you must still file a replacement return.

Are you correcting the identifying details of a previous annual information return?

When making corrections to annual information, you are always replacing a previous return with a new return. This means that a taxpayer can only have one return with the same identifying details. Identifying details include the payor’s ID (personal ID or Business ID), the tax year, the ID of the beneficiary of income or other taxpayer (personal ID or Business ID), and the type of payment.

If you need to make correction to the identifying details that you had filed previously, you must first delete the original return. Then file a new return with the correct identifying details. Each annual information return’s identifying details are listed in the relevant instructions and data format specifications.

Making corrections electronically

You cannot make corrections to the following annual information returns electronically, if the year of payment is 2015 or earlier:

  • Annual Information Return – Employer Payroll Report; Payor Information and Itemisations
  • Annual notification – payments to recipients with limited tax liability (to nonresidents)
  • Annual information return, specification of pension benefits, social benefits
  • Annual information return on dividends
  • Annual information return on distributions profit surplus by a cooperative society
  • Annual information return on payments of interest and aftermarket bonuses as governed by the Income Tax Act
  • Annual information return concerning paid interest as governed by the act on tax withheld at source on interest
  • Annual information return on prices paid for timber

In addition, if you need to make corrections to other annual information returns than those listed above concerning the year 2017 or earlier, you cannot make them electronically. Corrections for older years must be made on paper forms.

Frequently asked questions

Because the year of payment is one of the identifying details, you must submit a replacement summary to delete the original return. Include the required identifying details on the summary: payor’s Business ID, the incorrect year of payment, the tax year, and the date of the decision to distribute dividends.

Delete the previously filed itemisations of dividend beneficiaries by filing replacement returns that only include their personal IDs and no other information. Then file a new annual information return with the correct details.

Because the beneficiary’s personal ID is one of the identifying details on the information return on dividends, you will have to file two new returns in order to correct it.

You can make the correction electronically as follows:

First, file a replacement annual information return that only contains the incorrect personal ID for the recipient concerned, and include the other identifying details from the original return: the payor’s ID, tax year and payment type. If you leave all other fields empty, the incorrect return is deleted. Then file a new annual information return with the correct personal ID and all the other information included in the original return.

If you file corrections to annual information on paper, you will also have to file all the details for the summary again.

If you cannot generate a replacement return with the same software you used for the original return, you can make corrections to specific itemisations by filing a web form on Lomake.fi (tax.fi > e-File > Annual information return) or on paper. If you file the correction on a web form or on paper, the replacement return’s identifying details do not include the code indicating the software used to generate the file. However, other identifying details must be the same as on the original return.

If a different accounting firm handles your bookkeeping for the latter months of the year, it is your responsibility as the payor to ensure that the information from the start of the year is transferred over to the new accounting firm. The amounts from the start and the rest of the year must be added up before filing the annual information return. Otherwise, only the information from the last part of the year will be taken into account in the income tax assessment of the individuals concerned. In other words, you will still only file one annual information return for the year even if you changed your accountant mid-year.

If your accounting software has changed during the year, the user of the new software has to add up the amounts from the start of the year and the rest of the year before filing the annual information return. If the amounts cannot be combined this way, you can file the annual information as two separate files. However, the two files must have different codes indicating the software used to generate them. When you submit two files with the same beneficiary but with different software codes, the files do not replace one another, and both will remain active.
