Frequently Asked Questions

When is Finnish VAT due?
On the 12th of the second month after the VAT period: the March return and payment are due on 12 May. Quarterly filers pay on 12 May, 12 August, 12 November and 12 February; annual filers by the end of February. A due date on a weekend or public holiday moves to the next business day.
When do employers pay withholding and employer contributions?
By the 12th of the month after the payday month. Wages are reported to the Incomes Register within five days of each payday; the employer's separate report on health insurance contributions is due by the 5th of the following month.
When is the corporate income tax return due?
Within four months of the end of the last month of the accounting period — 30 April for companies whose accounting period is the calendar year.
When do individuals have to check their pre-completed tax return?
In spring 2026 the due dates were 1, 14, 21 or 28 April; each taxpayer’s own date is printed on the return and in MyTax. Back tax for 2025 is payable in instalments on 3 August and 1 October 2026.
How often is VAT filed in Finland?
This calendar shows a monthly VAT filing — 13 of them across the 2026–2027 calendar. Filing frequency depends on the turnover band and the scheme a business is registered under, so a smaller business may report less often than the monthly cycle listed here. Confirm your own frequency with Finnish Tax Administration (Verohallinto).
When is the corporate income tax return due in Finland?
Apr 30, 2026 — Corporate income tax return for 2025 (calendar-year companies) and Apr 30, 2027 — Corporate income tax return for 2026 (calendar-year companies). Finland's tax year in this calendar runs January 1 to December 31, so a company on a non-calendar financial year will have different dates. Finnish Tax Administration (Verohallinto) publishes the authoritative schedule.
When is the personal income tax return due in Finland?
Apr 1, 2026 (Pre-completed tax return for 2025 — due date 1 April (if shown on your return)), Apr 14, 2026 (Pre-completed tax return for 2025 — due date 14 April (if shown on your return)), Apr 21, 2026 (Pre-completed tax return for 2025 — due date 21 April (if shown on your return)) and Apr 28, 2026 (Pre-completed tax return for 2025 — due date 28 April (if shown on your return)). Extensions and agent-filed deadlines can differ; the dates above are the ones shown on this calendar.
How often are payroll and social security contributions paid in Finland?
The calendar lists 12 payroll & social security deadlines on the 12th for the 2026–2027 period — a monthly cycle. Employer obligations depend on headcount and payroll size.
What does this Finland tax calendar cover?
84 filing and payment deadlines for 2026–2027, grouped by month: vat, ec sales list, payroll & social security, personal income tax, corporate tax and prepayments. Each entry names the form where one applies and flags public holidays that fall near a deadline. The authority behind these dates is Finnish Tax Administration (Verohallinto).
Is this calendar official Finnish Tax Administration (Verohallinto) guidance?
No. It is a plain-English summary built to help you plan, and it is not tax advice. Dates can change, and your own obligations depend on your registration, turnover and scheme. Always confirm against Finnish Tax Administration (Verohallinto) before you rely on a date, and speak to a qualified adviser about your own situation.
Do EU-wide VAT rules change these Finland dates?
The EU VAT Directive sets a common framework, but each member state keeps its own filing calendar, thresholds and rates — which is why Finland has its own page here rather than a shared EU one. If you sell across borders, the One-Stop Shop lets you declare VAT centrally instead of registering in each country.

Before you file or pay

How to verify a Finland tax deadline

1. Match the obligation. Check the tax type, period, registration and filing method. A VAT, payroll or income-tax date may not apply to every taxpayer.
2. Check the live notice. Public holidays, agent arrangements, extensions and account-specific instructions can change the operational due date.
3. Keep proof. Save the submission receipt and payment confirmation. Filing and paying can be separate actions with separate cut-off times.

Why this matters: missed dates can lead to late filing charges, interest, loss of a relief or an avoidable compliance review. This page is a planning aid, not a legal determination. It was last content-reviewed on 2026-10-09; verify the live rule with Finnish Tax Administration (Verohallinto) before acting.
