Claim for adjustment of a decision on self-assessed taxes
Businesses and corporations can ask for adjustment of a decision regarding self-assessed taxes.
Self-assessed taxes include VAT, excise duty and employer’s contributions, such as tax withheld on wage payments and the employer's health insurance contribution. If you want to claim adjustment regarding registration, see the instructions on claims for adjustment concerning registration matters
Businesses and corporations can also appeal against late-filing penalties: If you had a special reason for filing your tax return late, you can request that the Tax Administration should not charge the late-filing penalty. Read more about non-recovery of late-filing penalty
Decisions that are accompanied by “Instructions for appeal” can be appealed against.
Please note: If you are, in the year 2023, claiming adjustment of decisions made in 2020, you cannot make the claim in MyTax. Make a free-form claim for adjustment and submit it to the Tax Administration together with the form 4015e: Claim for adjustment of self-assessed taxes, cover page.
Instructions on claims for adjustment
When can a claim for adjustment be filed?
You can make a claim for adjustment within 3 years from the start of the year following the relevant tax period.
When the last day of the time limit is a public holiday, the Independence Day, the 1st May, the Christmas Eve or Midsummer Eve or a regular Saturday, the claim for adjustment may be filed with the Tax Administration on the next weekday.
The claim for adjustment must arrive at the Tax Administration on the due date by 4.15 pm.
Example: A company receives a decision issued by the Tax Administration in January 2023 concerning the tax period of November 2022. If the company files a claim for adjustment, the claim must arrive at the Tax Administration by 31 December 2025. The company’s accounting period is the calendar year.
Note the exceptions:
- If the company’s or organisation’s accounting period is not the calendar year but the tax period is the calendar month: The 3-year period of appeal starts at the beginning of the year following the end of the accounting period.
- A claim for adjustment concerns a registration decision, authorisation decision or another special decision: The claim for adjustment must be filed within 60 days from the date when the decision is received.
Example A: A company has two accounting periods ending during the calendar year 2022: 1 July 2021 to 30 June 2022 and 1 July 2022 to 31 December 2022. The company can claim adjustment of tax decisions concerning these periods until 31 December 2025.
Example B: On 11 January 2023, a company was given a decision on an authorisation. If the company files a claim for adjustment, the claim must arrive at the Tax Administration by 12 March 2023.
However, the appeal period is always at least 60 days from the date when the decision is received.
Always check the due date for appeal in the instructions for appeal enclosed with the decision.

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 you are approved for a payment arrangement and you have no other unpaid taxes, the amount you have overpaid in taxes will be returned to you with interest.
You can cancel a claim for adjustment fully or partially. In MyTax, go to the ‘Activity’ tab. Select ‘Cancel a claim for adjustment’ under ‘Claims for adjustment’.
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 when you claim for adjustment or separately later.
If you intend to pay the tax in full regardless of claiming for 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 taxes have not yet been transferred to the National Enforcement Authority.
If your claim for adjustment is rejected, your request for a prohibition of enforcement is also rejected. In this case, the unpaid tax may be transferred to enforcement. However, the National Enforcement Authority may not sell any seized property, apartment shares or shares in a jointly administered real estate unit while your claim for adjustment is being processed.
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.
