For US citizens and green card holders in Finland

US Taxes for Americans Living in Finland

Moving to Finland does not end your US tax filing. Here is what Americans living there file each year, how the treaty and the social security rules between the two countries work, and what to do about missed years.

Quick answer

Do US citizens living in Finland have to file US taxes?

Yes. The US taxes citizens and green card holders on worldwide income wherever they live. Living in Finland gives an automatic extension to June 15, accounts there above US$10,000 in total need an FBAR, and the foreign tax credit or the foreign earned income exclusion (US$132,900 for 2026) usually prevents double tax. The US has an income tax treaty with Finland, and a social security agreement has been in force since November 1, 1992.

Do Americans living in Finland have to file US taxes?

Yes. The United States taxes its citizens and green card holders on worldwide income wherever they live, so moving to Finland does not end the yearly US return (IRS Pub 54). Salary, self-employment income, interest and pensions from Finland all go on it, converted from euros to US dollars.

The return is due April 15. If you live and work outside the US on that date, you get an automatic 2-month extension to June 15, and you can extend further to October 15. Interest still runs on tax paid after April 15.

Will I pay tax twice living in Finland?

Most Americans in Finland end up owing little or no US income tax, because tax paid in Finland or the exclusion of foreign earnings offsets it. The exclusion covers up to US$130,000 of earned income for 2025 and US$132,900 for 2026 (IRS); the foreign tax credit instead uses the income tax you paid in Finland.

The US has an income tax treaty with Finland (IRS treaty list), but US treaties contain a saving clause: they generally do not reduce US tax for US citizens, with specific exceptions written into each treaty (IRS Pub 54). So the treaty helps at the edges, for example with pensions or the order of tax credits, while the main relief comes from the exclusion or the credit.

See FEIE vs foreign tax credit for how the two compare.

Your accounts in Finland: FBAR and Form 8938

Bank, pension and investment accounts in Finland are foreign accounts for US purposes.

FBAR: required when your foreign accounts total more than US$10,000 at any time in the year. Due April 15, with an automatic extension to October 15 (IRS).
Form 8938: filed with the return when foreign financial assets pass higher thresholds; for a single person living abroad, more than US$200,000 at year end or US$300,000 at any time (US$400,000 and US$600,000 for a joint return). Not filing can cost US$10,000 (IRS).

Catching up on US filings

Catching up is usually possible without penalties. The Streamlined Foreign Offshore Procedures ask for 3 years of returns and 6 years of FBARs, with any tax and interest paid, and for eligible people living outside the US the penalties for late returns, information returns and FBARs do not apply (IRS). Eligibility turns on non-willful conduct and on meeting the non-residency test while in Finland. See Streamlined filing.

Working with your adviser in Finland

Americans in Finland include researchers, tech and gaming employees and spouses of Finnish citizens.

We do not advise on the tax law of Finland. A local adviser handles your return there; we prepare the US return and filings and use the tax you paid in Finland for the credit. For the wider picture, see US tax for Americans in Europe.

Treaty and social security

The IRS lists the 1989 income tax treaty. General effective date (IRS Table 3): treaty Jan. 1, 1991; protocol Jan. 1, 2008 (IRS treaty documents for Finland; treaty text; IRS Table 3).
Saving clause: paragraph 3 of Article 1 (Personal Scope), which lets the United States tax its citizens as if the treaty had not come into effect, apart from listed exceptions.
Article 23 (Elimination of Double Taxation), on relief from double taxation.
Article 18 (Pensions, Annuities, Alimony, and Child Support), on pensions and social security.
Article 15 (Dependent Personal Services), on employment income.
Social security: the US agreement with Finland entered into force on November 1, 1992 (SSA).

US law

Foreign earned income exclusion: Code section 911 (IRS Form 2555 instructions).
Foreign tax credit: Code section 901 (IRS Pub 54).
Form 8938: Code section 6038D and Treas. Reg. section 1.6038D (IRS Form 8938 instructions).
FBAR: 31 USC 5314 and 31 CFR 1010.350 (IRS Internal Revenue Manual 4.26.16).

The tax rules of Finland also apply to you there; a local adviser covers that side.

Common questions

Do Americans in Finland pay US tax?

Yes. US citizens and green card holders file a US return on worldwide income wherever they live. Living in Finland on April 15 gives an automatic extension to June 15, and tax paid in Finland or the foreign earned income exclusion often reduces the US tax to little or nothing.

Does the US-Finland tax treaty stop double taxation?

Partly. The treaty exists, but its saving clause lets the US tax its own citizens as if there were no treaty, with listed exceptions. The main relief is the foreign tax credit or the foreign earned income exclusion.

Do I pay social security in both the US and Finland?

Generally not. The US-Finland social security agreement, in force since November 1, 1992, assigns your work to one system.

What if I never filed US taxes while living in Finland?

If it was not willful, the Streamlined Foreign Offshore Procedures let you file 3 years of returns and 6 years of FBARs, and eligible people living abroad do not pay the usual failure-to-file, information return or FBAR penalties.
