Most countries make you do your own tax return. Finland, with its pre-filled forms and a state that already knows what you earned, mostly does it for you. That is the charming part of income tax in Finland, and it is why this guide to income tax in Finland starts with how it works: if you are an employee with a simple situation, the system is almost frictionless. The less charming part is that your first year is anything but simple.
This guide explains when you become a Finnish tax resident, how the 2026 tax is built, how the tax card works, and the special regime for foreign experts.
When does tax residency in Finland start, and what does it mean?
Vero says that if you stay in Finland for more than six months you are liable to tax in Finland on income from Finland and from abroad. If you live abroad, you are taxed only on Finnish income. Short absences do not interrupt the stay.
A subtle point: you do not have to wait six months. If you move for good, with a home, family and job, your permanent home is in Finland from the day you arrive and you are resident from then. Residents declare their worldwide income, and the tax treaty with your previous country decides which country may tax each type of income, to avoid double taxation. Finland has treaties with about 70 countries.
How is income tax in Finland calculated for a salary in 2026?
Several layers apply to earned income.
State income tax is progressive. In 2026 the scale is:
| Taxable earned income | Rate |
|---|---|
| Up to €22,000 | 12.64% |
| €22,000 to €32,600 | 19.00% (€2,780.80 on the first €22,000) |
| €32,600 to €40,100 | 30.25% |
| €40,100 to €52,100 | 33.25% |
| Above €52,100 | 37.50% |
Municipal tax is set by each municipality each year, and Vero publishes the 2026 list. For non-residents taxed progressively, Vero applies an average municipal rate of 7.60 per cent in 2026.
Church tax is due only if you are a member of the Evangelical Lutheran or the Orthodox Church of Finland; the parish sets the rate. If you do not join, you do not pay.
Social contributions in 2026 are withheld from pay: the health insurance contribution of 1.10 per cent, a daily allowance contribution of 0.88 per cent if your annual income reaches €17,255, the TyEL pension contribution of 7.30 per cent and the unemployment contribution of 0.89 per cent.
Yle tax, the public broadcasting levy: 2.50 per cent of income above €15,150, up to a maximum of €160 in 2026. On Åland, a media fee of €128 replaces it when income exceeds €14,000.
Employees also get an automatic deduction of €750 for work expenses in 2026, within the limit of salary. Trade union fees are no longer deductible from 1 January 2026; unemployment fund fees remain deductible. Capital income is taxed at 30 per cent up to €30,000 and 34 per cent above.
Not sure how much of your salary will actually reach your account, or whether a treaty applies to your old pension? Moovy can set out the steps for your situation and draft the Finnish message to Vero. For complicated cross-border income, ask a qualified tax adviser to validate it.
How does the Finnish tax card work?
You need a tax card (verokortti) to work, and applying for one requires a personal identity code (see the Finnish personal identity code). The first time you apply at a Vero service point, estimating your income for the whole year. After that, everything runs in OmaVero, Vero's online service, which asks for strong identification (see digital ID in Finland).
Show a copy to your employer. One card is valid for all employers, with a single annual income ceiling. Change it whenever your situation changes: a raise, a second job, deductions. If your real income exceeds the ceiling on your card, you pay the difference as extra tax in the autumn.
Without a card, the employer can withhold 60 per cent. This is refunded later, but it makes your first months thin.
What is the key employee regime?
For foreign experts, Finland offers a flat tax at source. Since 1 January 2026 it is 25 per cent on wages (it was 32 per cent until 2025). Conditions:
- a cash salary of at least €5,800 a month, fringe benefits excluded (no minimum for teaching and research in higher education);
- a job requiring special expertise;
- you must not have been a Finnish tax resident in the five calendar years before;
- it applies for the first 84 months of work (60 months for a Finnish citizen returning from abroad).
You apply for a special tax card on form 5042e, ticking the "key person" box, within 90 days of starting the job named in your contract. Prepare the application before you arrive, and contact Vero at once if the 90 days have passed. Under this regime you pay no Finnish health insurance contribution; your employer withholds pension and unemployment contributions unless you hold an A1 certificate. Compare it with the progressive scale if your salary is high, because the treaty with your home country can change the result. See working in Finland.
What about short stays and non-residents?
If you come to work six months or less and keep your home abroad, you are a non-resident. Your Finnish wages are usually subject to a final 35 per cent withholding after a deduction of €510 a month (€17 a day for less than a month), applied if it appears on your tax-at-source card. Residents of the EEA, and of countries covered by the multilateral convention or an information exchange agreement, can ask for progressive taxation instead. That choice applies for the whole tax year.
What happens in spring and autumn?
In spring, Vero sends your pre-completed return (esitäytetty veroilmoitus). It lists your income and tax for the previous year. If it is right, you do nothing. If not, correct it before the date printed on it; in 2026 those dates were 1, 14, 21 or 28 April depending on the person. You declare what Vero does not know: foreign income, rental income, and deductions such as commuting costs or expenses above the automatic deduction. In 2026 most refunds were paid on 3 August or 3 September, and balances were due in two instalments, on 3 August and 1 October; a corrected return brings a new decision by the end of October. Your own dates are shown in OmaVero.
How does your home country's tax treaty change the picture?
Residence in Finland puts all your income in the Finnish net, but a tax treaty decides who may tax what. Finland has treaties with about 70 countries, and Vero says most eliminate double taxation by a credit, with a few exceptions such as France, where Finland uses exemption. For French residents moving to Finland, the 1970 convention, as modified, generally reserves private pensions for Finland and leaves public-service pensions to France, which Finland may take into account when setting the rate on your other income. A new France-Finland convention signed on 4 April 2023 entered into force on 28 August 2026 and applies in Finland from 1 January 2027, according to Finnish decree 34/2026, so the rules change for 2027 income. Which of your pensions is public or private is a technical question; ask a tax adviser.
For Nordic salaries, Vero points to the Nordic eTax portal. For everyone else, check the pensions and employment articles of your treaty and keep the foreign income statements you will need for the return.
What other taxes appear later?
If you buy a home, the owner pays property tax each year and a transfer tax at purchase (1.5 per cent on housing shares and 3 per cent on real estate in 2026). If you import a car, you pay the one-off car tax and then an annual vehicle tax. If you start a business, VAT and prepaid tax come into play. See buying property in Finland and driving in Finland.
Which mistakes should you avoid?
- Waiting six months to think about tax. You can be resident from day one.
- Forgetting income from your old country: the pre-completed return does not know it.
- Leaving the card rate too low after a raise.
- Joining a church without realising it brings church tax.
- Applying for key employee status after the 90 days.
If you keep a pension, property or business abroad, have your situation confirmed by a Finnish tax adviser or accountant before you decide. The Finnish side is predictable; the cross-border side is where mistakes cost money. Next, see how tax fits into your budget in cost of living in Finland.
