Finland Cross-Border Tax Guide 2026 — Non-Resident Tax & Lähdevero

for international taxpayers in Finland. The guide covers: the non-resident taxation regime (the lähdevero — the flat withholding tax system for non-residents, the general rate of 35% on dividends paid by Finnish companies to non-residents, the reduced treaty rates that can bring the withholding down to 0-15% depending on the treaty and the holding percentage, the requirement to claim treaty relief via the simplified refund procedure or the advance tax ruling), the non-resident income tax (the lähdeverolaki — the Act on Withholding Tax for Non-Residents, the flat 35% rate on Finnish-source dividends, interest, royalties, and pensions, the exceptions for EU/EEA residents who may elect to be taxed under the progressive rates with certain deductions), the double taxation treaties (Finland's extensive treaty network — over 70 treaties including the UK, the United States, Germany, France, the Netherlands, Sweden, Norway, China, Japan, and most EU/EEA countries — the standard dividend withholding rates of 0-15%, the interest rate of 0%, the royalty rates of 0-10%, the pension article which typically assigns the taxing right to the country of residence), the taxation of inbound expats (the special 32% flat tax regime for highly paid expatriates — the lähdeveromenettely for key employees and experts, available for up to 7 years, requiring a minimum monthly salary of approximately €6,000-€7,000, the source tax is a final tax with no deductions), the taxation of outbound expats (the exit tax concerns for individuals moving from Finland — the realisation of capital gains on departure, the rules for maintaining Finnish tax residency, the requirement to notify the tax authority), the permanent establishment risk for foreign companies (the 6-month rule for construction and service PEs, the agency PE rules, the requirement to register with the Finnish Trade Register and Tax Administration), and the reporting obligations for cross-border transactions (the transfer pricing documentation requirements, the country-by-country reporting for large multinational groups, the advance pricing agreements available from Verohallinto).

Finland has a comprehensive network of tax treaties and offers a competitive 20% corporate tax rate. All amounts in Euros (EUR). For related reading, see our Tax Residency Guide →.

Non-Resident Taxation (Lähdevero)

Non-residents in Finland are subject to the withholding tax system (lähdeverolaki, Laki rajoitetusti verovelvollisen tulon verottamisesta). The key features are:

General rule: Non-residents are taxed only on Finnish-source income, primarily through a final withholding tax (lähdevero). The standard rate is 35% on most Finnish-source passive income (dividends, interest, royalties, and pensions).
Dividends: Dividends paid by Finnish companies to non-resident shareholders are subject to a 35% withholding tax. This rate can be reduced under an applicable double taxation treaty (typically to 0-15%), but the reduced rate must be claimed — either through the simplified refund procedure (palautushakemus) or by providing a certificate of residence to the payer before the payment.
Interest and royalties: Interest paid by Finnish entities to non-residents is generally exempt from Finnish withholding tax (0%) under domestic law, unless the interest is profit-sharing or paid to a related party in a non-treaty country. Royalties are subject to the 35% withholding rate unless reduced by a treaty (typically 0-10%).
Pensions: Finnish-source pensions paid to non-residents are subject to a 35% withholding tax, unless a treaty assigns the taxing right exclusively to the country of residence (as most Finnish treaties do).
EU/EEA residents: Non-residents who are resident in an EU/EEA country can elect to be taxed under the progressive rates of the state income tax (valtionverotus) instead of the flat 35% withholding, allowing them to claim deductions and personal allowances if they earn more than 75% of their total income from Finnish sources.

Dividend Withholding to Non-Residents

Dividends from Finnish companies to non-residents are subject to the following withholding structure:

Default rate: 35% on gross dividends paid to non-residents.
Treaty rates: Most Finnish treaties reduce the rate significantly: (a) EU parent-subsidiary directive: 0% for qualifying holdings (≥10-25%, held for at least 12 months), (b) standard treaty rate: 0-15% depending on the treaty and the holding percentage, (c) portfolio dividends (holdings <10%): typically 15%.
Claiming treaty relief: The non-resident must provide a certificate of residence (verotodistus) to the Finnish paying agent before the dividend payment, or apply for a refund of the excess withholding via the Verohallinto's refund procedure (modelo 7105 or the electronic service). The refund can take 6-12 months to process.

Double Taxation Treaties

Finland has over 70 double taxation treaties, largely following the OECD Model Convention. Key provisions:

UK-Finland Treaty: Dividends: 0% for holdings ≥10%, 15% for portfolio. Interest: 0%. Royalties: 0-5%. Pensions: taxable only in the country of residence.
US-Finland Treaty: Dividends: 0% for certain institutional investors, 5% for holdings ≥10%, 15% for portfolio. Interest: 0% (30% for contingent interest). Royalties: 5%. Pensions: taxable in the country of residence. Social Security: only the source country taxes.
Sweden-Finland Treaty: Dividends: 0% for holdings ≥10% (Nordic Convention), 15% for portfolio. Interest: 0%. Royalties: 0-5%. This follows the Nordic Multi-Lateral Treaty provisions.
Germany-Finland Treaty: Dividends: 5% for holdings ≥10%, 15% for portfolio. Interest: 0%. Royalties: 5% (0% for copyright). Pensions: taxable only in residence country.
Mutual Agreement Procedure (MAP): Available under all Finnish treaties. The Finnish tax authority (Verohallinto) and the competent authority of the treaty partner resolve disputes regarding double taxation, transfer pricing, and residency conflicts.

Special Expatriate Regime (32% Flat Tax)

Finland offers a competitive tax regime for highly paid expatriates:

Rate: A flat 32% tax on employment income for qualifying key employees and experts. This is the source tax (lähdevero) regime under the Act on the Taxation of Non-Residents (laki rajoitetusti verovelvollisen tulon verottamisesta).
Duration: The regime applies for a maximum of 7 years (4 years initially, extendable by 3 years).
Minimum salary: The employee must earn at least approximately €6,000-€7,000 per month (the exact threshold is indexed annually).
Eligibility: The employee must (a) be a key employee or expert with special expertise not readily available in Finland, (b) be hired from abroad, (c) not have been a Finnish tax resident in the 5 years prior to the move, and (d) apply for the regime within 90 days of starting work.
Effect: The 32% is a final tax — no deductions are available, but no social security contributions are payable on the income covered by the source tax (the employee still pays pension contributions separately). The regime does not cover investment income, which is taxed at standard rates.

Permanent Establishment Risk

Foreign companies with operations in Finland may create a permanent establishment (PE — kiinteä toimipaikka):

Fixed place of business: A PE is created if the foreign company has a fixed place of business in Finland through which activities are wholly or partly carried out, including an office, a branch, a factory, or a workshop.
Construction PE: A building site or construction project lasting more than 6 months (or 12 months under some treaties) creates a PE.
Service PE: Under many treaties, providing services through employees or personnel in Finland for more than 183 days in any 12-month period creates a service PE.
Agency PE: A dependent agent who habitually concludes contracts on behalf of the foreign company in Finland creates a PE.
Consequences: A PE must (a) register with the Finnish Trade Register (Kaupparekisteri) and the Tax Administration (Verohallinto), (b) file annual corporate tax returns for the PE's Finnish-source profits at 20%, (c) maintain Finnish accounting records, and (d) comply with transfer pricing documentation requirements.

Frequently Asked Questions

Can I claim treaty relief on Finnish dividends without filing a refund?

Yes, if you provide a valid certificate of residence (verotodistus) from your home country's tax authority to the Finnish paying agent (the company or the custodian) before the dividend payment date. The paying agent will then apply the reduced treaty rate at source. If the full 35% was already withheld, you must file a refund application with Verohallinto within 3 years of the end of the tax year in which the dividend was paid.

What is the difference between the 32% expat regime and the standard progressive tax?

The 32% expat regime (source tax) is a flat, final tax on employment income with no deductions or credits available. The standard progressive system taxes employment income at rates of 0-56.5% (including municipal tax and church tax) but allows deductions (work expenses, interest, pension contributions, commuting costs). The expat regime is beneficial for high earners who would otherwise be in the top brackets (e.g., 50%+), but you must apply within 90 days of starting work in Finland.

Do I need to pay Finnish tax if I work remotely for a foreign company while in Finland?

If you are a Finnish tax resident (present >183 days or have your centre of interests in Finland), you are taxed on your worldwide income, including salary from a foreign employer. The foreign employer may need to register as a Finnish employer and withhold Finnish taxes. If you are a non-resident working in Finland for more than 183 days cumulatively, you may become a tax resident and trigger a PE for the foreign employer. Short business visits (less than 183 days per year) are generally exempt from Finnish tax if the employer is not Finnish and the salary is borne by a foreign entity, under most treaties.

What is the procedure for obtaining a certificate of residence for treaty relief?

To obtain a Finnish certificate of residence (verotodistus) for claiming treaty benefits abroad, you must file a request with the Verohallinto (the Finnish Tax Administration). The certificate confirms your Finnish tax residency for a specific period. It can be obtained via the OmaVero online service or by filing form 7601. The certificate is typically issued within 1-2 weeks. For use outside the EU, an apostille may be required.

Are capital gains on Finnish shares taxable for non-residents?

Under Finnish domestic law, non-residents are generally not taxed on capital gains from the sale of Finnish shares unless they own ≥10% of the company's capital (substantial shareholding) and the company's assets consist mainly of Finnish real estate. Most Finnish treaties provide that capital gains from shares are taxable only in the country of residence of the seller, except for shares deriving their value mainly from real estate (in which case Finland retains the taxing right).
