Finland has been quietly repositioning itself as one of the most tax-competitive destinations in Northern Europe. The next major move is confirmed: the corporate income tax rate drops from 20% to 18% effective January 2027, making it the lowest in the Nordic region and well below most Western European peers.
If you run a Finnish company, are considering setting one up, or are planning any significant business decisions in 2026, this change is worth understanding in full. Not because of the headline number, but because of the compounding effect when combined with two other reforms already in place: the 25-year loss carryforward introduced in 2026, and a suite of R&D and green investment incentives that reduce effective rates further still.
This article explains what changes, what stays the same, and most practically, what you can do now to be in the best position when the new rate takes effect.
What exactly is happening, and when
Finland has operated on a flat 20% corporate income tax (CIT) rate since 2014. It applied to all resident companies, including the Osakeyhtiö (Oy), Finland's standard limited liability company structure, on their worldwide taxable profits. From January 1, 2027, that rate drops to 18%.
The change was formally announced as part of the Finnish Government's Mid-Term Policy Review in April 2025 and confirmed in the government's fiscal plan for 2026 to 2029. The rate reduction affects financial years that begin in 2026 and end in 2027, as well as all subsequent years.
Timing note: If your company has a standard calendar financial year (January to December), the 18% rate will apply for the first time to your 2027 accounts. Companies with non-standard financial years ending during 2027 also fall within scope. Your 2026 accounts are still taxed at 20%.
The 2% reduction may not sound dramatic. On €200,000 of taxable profit, it means €4,000 less in corporate tax per year. For companies with higher margins, faster growth, or international scale, the numbers compound quickly, and they compound on top of structural advantages that are already in place.
How Finland now stacks up against the rest of Europe
Finland has held the lowest corporate tax rate in the Nordic region since its last adjustment. With the move to 18%, that position strengthens considerably.
| Country | CIT Rate | Notes |
|---|---|---|
| Finland From 2027 | 18% | Lowest in Nordics; confirmed Jan 2027 |
| Sweden | 20.6% | Flat rate, no further reductions planned |
| Norway | 22% | Stable; higher for financial sector |
| Denmark | 22% | |
| Germany | ~30% | Includes trade tax |
| Netherlands | 19 to 25.8% | Tiered; lower rate for first €200k |
| Croatia / Cyprus | 18% / 12.5% | On par or lower, but different environments |
| Estonia | 0% (retained) / 22% | Tax only on distributed profits |
Finland's rate will sit below almost every major Western European economy and broadly on par with Croatia. It remains above Ireland's 12.5%, which Finland explicitly benchmarks against for foreign direct investment, particularly in fintech and data infrastructure. But what Finland offers that Ireland does not is EU single market access combined with a stable regulatory environment, a well-developed digital tax administration, and a talent base that punches well above its population size.
The rate cut is only part of the reform
The 18% rate gets the attention, but two other changes, one already in force, significantly affect the actual financial position of Finnish companies.
Loss carryforward: 10 years to 25 years
From the 2026 tax year, confirmed tax losses can be carried forward for 25 years rather than 10. This is a substantial structural improvement, particularly for early-stage companies, capital-intensive businesses, and any company going through a period of investment-led loss.
The practical effect is that a loss recorded in 2026 can still offset taxable profit all the way through to 2051. Companies that previously wrote off older losses as unusable now have significantly more flexibility in managing their tax position across growth phases.
Important caveat: Losses are forfeited if more than 50% of the company's shares change hands during the year the loss arose. Companies considering share transfers, investment rounds, or restructuring should review existing loss positions with an advisor before any transaction.
R&D deductions: two parallel incentives
Finland operates two R&D tax incentive schemes simultaneously. The general combined R&D deduction, permanent from 2023, provides a 50% additional deduction on eligible R&D costs, plus a further 45% on year-on-year increases in R&D spending. The cooperation-based deduction, running through 2027, offers a 150% deduction on R&D costs subcontracted to recognised research organisations.
Both schemes have a minimum threshold of €5,000 and a cap of €500,000 per year. For qualifying companies, the combined effect is material: the effective cost of R&D activity, when tax savings are factored in, is substantially below the nominal expenditure.
Green investment tax credit
For companies involved in large-scale clean transition projects, including renewable energy, green hydrogen, and industrial decarbonisation, a 20% tax credit applies on qualifying investment costs. The credit is deducted from corporate income tax over 20 years, with a maximum of €150 million per company or group. Projects must comply with the EU's "Do No Significant Harm" principle and be completed within 36 months of approval.
What this means in practice for your company
The rate change is confirmed and takes effect from January 2027. That gives companies operating in, or considering a move to, Finland a defined planning window. Here are the questions worth working through before the change takes effect.
-
Review your 2026 tax position now. The 20% rate still applies to your 2026 financial year. If you have significant deductions available, including R&D costs, capital expenditure, or qualifying business expenses, consider whether accelerating or deferring any of these between years produces a better outcome at 20% vs 18%.
-
Map your loss position. If your company has confirmed losses from 2026 onwards, these now carry forward for 25 years. Run a clean inventory of your loss position and ensure it is correctly documented in your accounts. For losses pre-2026, the 10-year limit still applies.
-
Assess R&D eligibility. If your company conducts any form of product development, technical research, or process innovation, there is a reasonable chance that some portion of that work qualifies for the R&D additional deduction. This is one of the most underutilised incentives in the Finnish tax system.
-
Consider Finland as your EU base. For international entrepreneurs and founders currently assessing where in Europe to establish a legal presence, the combination of 18% CIT, a functioning digital company infrastructure, and EU single market access is a compelling package. The 1Office company formation service handles the full Y-tunnus registration process remotely.
-
Review dividend timing and distribution planning. Your company's profit distribution strategy should be reviewed in light of both the rate change and the withholding tax rules that apply to non-resident shareholders. The specific structure matters: EU parent companies holding at least 10% of Finnish company capital face 0% withholding tax on dividends.
The fundamentals that stay in place
A lower rate doesn't change the underlying structure of Finnish corporate taxation, which is worth understanding clearly.
Finland taxes resident companies on their worldwide income. The tax base is the company's taxable profit, calculated as revenue minus deductible expenses, after adjustments for depreciation and incentives. Corporate tax returns are due within four months of the financial year end (for calendar-year companies, that is 30 April). All filings go through the MyTax portal, Finland's digital tax administration system.
VAT obligations remain unchanged. The standard rate is 25.5%, with a reduced rate of 13.5% applying to food, accommodation, books, and similar goods and services. VAT registration is mandatory once annual turnover exceeds €20,000.
Employer social contributions, covering pension insurance, unemployment insurance, and health insurance, remain at approximately 19 to 21% of gross wages. These are separate from corporate income tax and unaffected by the CIT rate change.
Setting up in Finland ahead of the rate change
One of the more interesting dynamics of the 2027 rate confirmation is the planning window it creates for companies not yet operating in Finland. If you are establishing a Finnish entity in 2026, it will be ready and operational, with full accounting, tax registration, and compliance infrastructure in place, when the lower rate kicks in from January 2027.
Finland is particularly well-suited for remote founders, international tech companies, and EU market entrants who want a credible, low-friction Northern European base. The combination of a digital company infrastructure, English-speaking accounting and legal services, and now a confirmed 18% corporate rate from 2027 makes the case more concrete than it has been for years.
