More information and instructions on claiming adjustment
Yes, you must pay your taxes on their due date even if you have claimed adjustment. Interest for late payment is collected on unpaid taxes.
Call the Finnish Tax Administration’s service number +358 29 497 026 (Maksuliikenne) for the payment details. You can also check the details you need for making payments in MyTax: How to pay taxes in MyTax.
If you have difficulties paying your taxes by the due date, we recommend finding out whether you are eligible for a payment arrangement. Read more on requesting a payment arrangement
If your claim for adjustment is accepted and you have no other tax debt, the tax you paid in excess will be automatically refunded to you with interest.
A suspension of enforcement means that your taxes are not transferred to enforcement or that an already started enforcement is suspended for the time your claim for adjustment is processed. You can request for the suspension of enforcement either simultaneously with your claim for adjustment, or afterwards.
If you intend to pay the tax in full regardless of having claimed adjustment, we do not recommend requesting a suspension of enforcement.
If you request a suspension of enforcement, keep the following in mind:
- Late-payment interest will be collected on the tax for the duration of the suspension as well, i.e. starting from the original due date of the tax until the date you pay the tax.
- Tax refunds cannot be used towards back taxes during the suspension.
- You cannot obtain a tax debt certificate or a certificate of paid taxes during the suspension.
The suspension of enforcement can be full or partial.
The enforcement of a tax can be suspended in two ways:
- Full suspension: The taxes are not transferred to enforcement and your tax refunds or any payments you have made to the Finnish Tax Administration are not used.
- Partial suspension: Your tax refunds and any payments you have made to the Finnish Tax Administration can be used towards the payment of your taxes, the taxes can be transferred to enforcement and your other assets may be seized as well. However, the National Enforcement Authority may not sell the seized assets before your case is processed.
The enforcement of taxes can only be fully suspended if the unpaid taxes have not yet been transferred to the National Enforcement Authority.
If your claim for adjustment is rejected, your request for non-enforcement is rejected, as well. In this case, the unpaid tax can be transferred to enforcement. However, while your claim for adjustment is being processed, the National Enforcement Authority may not sell any seized property, a housing-company apartment, or shares in a jointly administered real estate.
You can cancel a claim for adjustment fully or partially. In MyTax, go to the ‘Tax matters’ tab. Select ‘Cancel a claim for adjustment’ under ‘Claims for adjustment’.
Yes, the Finnish Tax Administration can adjust your taxes on its own initiative after your tax assessment end date. This happens if the Tax Administration receives information afterwards that affects your taxation. As a result, you might receive tax refund, or it may be that you are ordered to pay more tax. Besides income taxes, the adjustments on the Tax Administration's initiative can concern income tax, real estate tax, value-added taxes, employer's contributions, and other types of taxes.
The Tax Administration can adjust your taxation within the same deadline that is applied to taxpayers’ claims for adjustment, i.e. within three years of the start of the tax year following the relevant tax year.
In some cases, the Tax Administration is allowed to extend the deadline by 1 year, and in some rare cases by 6 years.
The deadlines will also change in a situation where the need to adjust taxes is due to a criminal investigation process.
If you are unhappy with an adjustment made on the Tax Administration’s initiative, you can submit a claim for adjustment to request a review.
A decision on a claim for adjustment can be requested to be rectified by lodging an appeal to the administrative court. The deadline and instructions for appealing are in the appeal instructions appended to the decision.
