Self-Employed Tax in Finland

What is a Finnish sole trader and how is it taxed?

A Finnish sole trader operates under the legal form known as yksityinen elinkeinonharjoittaja (private trader) or toiminimi (trade name, abbreviated Tmi). There is no separate legal entity: the proprietor and the business are the same person in law. All net business income flows directly to the proprietor's personal tax return each year. Business registration is through the Finnish Patent and Registration Office (PRH) via the YTJ portal, which issues a Y-tunnus business identifier. The proprietor is personally liable for all business debts.

Under sections 38 to 41 of the Income Tax Act (Tuloverolaki, TVL 1535/1992), net business income is split each year between two streams before any personal tax is applied. This split is one of the distinctive features of Finnish self-employment taxation and determines whether income faces flat capital-income rates or progressive earned-income rates. [1]

How does the capital-income and earned-income split work?

Before the split, the Finnish Tax Administration (Verohallinto) automatically applies a 5% entrepreneur deduction (yrittajavahennys) to reduce net business income. This deduction is calculated automatically and appears in the tax decision without any action from the proprietor. It cannot exceed the year's profit.

After the deduction, remaining distributable business income is divided into two parts:

• Capital-income portion (paaomatulo-osuus): calculated as 20% of the net business assets (nettovarallisuus) at the end of the preceding tax year. Net business assets are business assets minus business liabilities; 30% of wages paid in the preceding 12 months is added to net assets for this calculation. This portion is taxed at the flat capital-income rate: 30% on amounts up to EUR 30,000 per year, and 34% on any amount above EUR 30,000. [1]
• Earned-income portion (ansiotulo-osuus): the remainder after the capital portion is subtracted. This is added to the proprietor's other earned income and taxed at progressive state and municipal rates.

The proprietor may elect to change how the capital portion is calculated by requesting a lower deemed return. Two elections are available, and both must be made before the tax assessment is finalised via section 17 of the business tax return (Form 5): (a) use a 10% deemed return instead of 20%, meaning less income is classified as capital income; or (b) treat all distributable business income as earned income (0% capital return). The 0% election can reduce the capital-income tax bill where the proprietor faces a low earned-income marginal rate, but is typically unfavourable for higher earners. [1]

Progressive state income tax rates for 2026 (earned income): 12.64% on income up to EUR 21,200; 19% on EUR 21,200 to EUR 32,600; 30.25% on EUR 32,600 to EUR 40,100; 33.25% on EUR 40,100 to EUR 52,100; and 37.50% on income above EUR 52,100. Municipal tax is charged on top at a flat rate set by each municipality, ranging from 4.70% to 10.90% in 2026. [2]

What is YEL pension insurance and why does it matter?

YEL (Yrittajan elakevakuutus, Self-employed Persons' Pension Insurance) is mandatory pension insurance for Finnish self-employed persons under the Self-Employed Persons' Pensions Act (Yrittajan elakelakit, YEL 1272/2006). It is not optional for those who meet all triggering conditions: aged 18 to 70, working as self-employed for at least four consecutive months, and earning at least EUR 9,423.09 annually from self-employment (the 2026 minimum threshold). [3]

The 2026 YEL contribution rate is 24.4% of confirmed YEL income (YEL-tyotulo), uniformly applicable regardless of age. This is a significant cost for most sole traders. A new entrepreneur discount of 22% is available for the first 48 months of self-employment, reducing the effective rate to approximately 19.0% during that period. YEL contributions are fully deductible from the proprietor's taxable income. [3] [4]

YEL income is not the same as actual business profit. The proprietor and their chosen pension provider agree on a confirmed YEL income figure that should reflect the value of the proprietor's own labour -- roughly equal to what an employer would pay an outside worker for the same work. The minimum confirmed income is EUR 9,423.09 and the maximum is EUR 214,000 (2026 figures). Setting YEL income at the minimum reduces current contributions but correspondingly reduces future pension and social-security benefits.

The YEL income figure directly determines entitlement to several Kela (Social Insurance Institution) benefits: sickness allowance, parental allowance, and rehabilitation allowance are all based on confirmed YEL income. Entrepreneurs who join the Entrepreneurs' Unemployment Fund (Yrittajakassa) can access earnings-related unemployment benefits, but only if their YEL income is at least EUR 15,481 per year. Below that amount, only Kela's basic unemployment allowance applies. [5]

YEL insurance is arranged directly with a licensed earnings-related pension company (such as Varma, Ilmarinen, Elo, or Veritas). The proprietor applies once and thereafter reports changes in work input to the insurer.

How does prepayment tax work for sole traders?

Sole traders do not have an employer to withhold tax from their income. Instead, they pay tax in advance through the prepayment tax (ennakkovero) system administered by Verohallinto. [6]

When starting a business, the proprietor estimates expected turnover, expenses, and taxable profit for the year and submits this estimate via the OmaVero portal (MyTax) or on paper Form 5010e. Verohallinto issues a prepayment decision specifying the amounts due and their payment dates -- typically two instalments per year for lower-income proprietors, or more frequent instalments for higher earners.

If actual income diverges from the estimate during the year, the proprietor can apply to adjust the prepayment amount upward or downward through OmaVero at any time. The annual business tax return (Form 5) is due by 1 April of the following year. If prepayments fall short of actual tax liability, the remaining balance is due after the final tax assessment, with interest charged on underpayments. If prepayments exceed actual liability, the excess is refunded.

Prepayme amounts are based on total expected tax on all income -- business income, wage income from other sources, capital income -- not just business profit alone. This means sole traders with mixed income sources must account for all streams when estimating. A qualified tax professional can help calibrate the estimate to avoid large year-end balances.

When is VAT registration required?

VAT (arvonlisavero, ALV) registration in Finland is mandatory when annual turnover exceeds EUR 20,000. This threshold was raised from EUR 15,000 effective 1 January 2025. [7] Businesses below EUR 20,000 may register voluntarily, which gives the right to reclaim input VAT on purchases but also creates an obligation to charge and remit output VAT to customers.

The VAT lower-limit relief scheme (alarajahuojennus) that previously provided sliding-scale relief for businesses with turnover below EUR 30,000 was completely abolished as of 1 January 2025. There is no replacement relief mechanism; above the EUR 20,000 registration threshold, the full VAT amount is due without reduction. [7]

The standard Finnish VAT rate is 25.5% (raised from 24% effective 1 September 2024). Reduced rates apply to food, restaurants, and hotels at 14%, and to books, public transport, and medicines at 10%. VAT returns are filed through OmaVero: monthly for businesses with annual turnover above EUR 100,000; quarterly for EUR 30,000 to EUR 100,000; and annually for businesses below EUR 30,000.

For most professional services, sole traders will charge VAT at 25.5% on invoices once registered. The full registered amount is remitted to Verohallinto after deducting any input VAT paid on business purchases.

Determining the optimal structure, setting YEL income at the right level, and timing prepayment adjustments all involve trade-offs that depend on each proprietor's specific circumstances. This page summarises how the system works; decisions on implementation should be made with a qualified tax professional.
