Tax residence in Ukraine for U.S. citizens and green card holders

Ukraine applies a cascade: a home in Ukraine; if you have homes in two countries, your center of vital interests; then 183 days or more in the calendar year; then citizenship. U.S. citizens remain taxable in the United States; the U.S.–Ukraine treaty settles dual residence.

When Ukraine treats you as a tax resident

The first criterion is whether you have a place of residence (a home) in Ukraine.

If your only home is in Ukraine, you are a Ukrainian resident. If you have homes in both countries, the centre of vital interests decides. Ukrainian law refers to a home in any foreign state; this tool asks about a home in the United States.

You have no home in Ukraine. If you have no home anywhere, the number of days spent in Ukraine decides.

The Tax Code names two sufficient indicators of the centre of vital interests: where your family lives and where you are registered as an entrepreneur.

FOP (fizychna osoba-pidpryiemets) is the Ukrainian registration of an individual entrepreneur.

Your personal and economic ties with each country are compared.

183 days or more — resident. Fewer — citizenship decides.

The condition is «sufficient but not exclusive»: the tax authority may also weigh other ties.

We check your days in Ukraine: in practice the tax authority and courts rely on border-crossing data.

Under the Tax Code the criteria apply in sequence, and 183 days matter only where the home or centre of interests cannot be determined (Second Administrative Court of Appeal, case 520/23643/24). At the same time the Supreme Court in case 461/1800/17 held a foreigner who spent more than 183 days in Ukraine to be resident.

We check your days in Ukraine: in practice the tax authority and courts rely on border-crossing data.

Your only home is in Ukraine — you are a Ukrainian tax resident.
Your family lives permanently in Ukraine — a sufficient condition for a centre of vital interests in Ukraine.
You are registered as an individual entrepreneur (FOP) in Ukraine — a sufficient condition for a centre of vital interests in Ukraine.
You have declared Ukraine as your main place of residence — a sufficient ground to treat you as resident.
Your centre of vital interests is in Ukraine.
You spent 183 days or more in Ukraine — you are a Ukrainian tax resident.
The earlier criteria gave no answer; as a citizen of Ukraine you are treated as a Ukrainian resident.

When you are a nonresident

Your centre of vital interests is in the United States; under the Tax Code you are probably not a Ukrainian resident.
You have no home in Ukraine but have one in the United States — under the Tax Code you are probably not a Ukrainian resident.
The earlier criteria gave no answer and you are not a Ukrainian citizen — you are probably not a Ukrainian resident.
You have no home in Ukraine but have one in the United States, so under the Tax Code you are probably a non-resident. But you spent 183 days or more in Ukraine — the tax authority may treat you as resident and you would have to rebut this with documents.
Your centre of vital interests is in the United States, so under the Tax Code you are probably a non-resident. But you spent 183 days or more in Ukraine — the tax authority may treat you as resident and you would have to rebut this with documents.

Where the rules of Ukraine clash with U.S. tax rules

Collision: Ukraine taxes you as a resident, the United States taxes you as a citizen. Under the Tax Code cascade (home → centre of vital interests → 183 days → citizenship) Ukraine treats you as resident and taxes your worldwide income. The United States taxes its citizens on worldwide income wherever they live. The Article 4(2) tie-breaker decides your treaty residence, but it does not remove U.S. tax: under the saving clause in Article 1(3) the United States may tax its citizens (and former citizens) as if the Convention had not come into effect, except for the benefits listed in Article 1(4) — including Article 24 relief and Article 19(1) social security. Double taxation is relieved by credits: Ukraine credits U.S. tax only with a certificate from the U.S. tax authority (p. 13.5 TCU), and the United States credits Ukrainian income tax (the U.S. foreign tax credit and the foreign earned income exclusion are explained in the U.S. section).
Collision: green-card holder or substantial-presence resident who is also resident in Ukraine. You are not a U.S. citizen but are resident in both countries under their domestic rules. The Article 4(2) tie-breaker settles your treaty residence. The saving clause (Article 1(3)) preserves U.S. taxation only of citizens, former citizens and residents as determined under Article 4 — so if the tie-breaker points to Ukraine, the United States may tax you only as a non-resident under the Convention. In that case U.S. regulations treat you as a nonresident alien for computing U.S. income tax; you file Form 1040-NR with Form 8833, you remain a U.S. resident for other Code purposes, and filing as a nonresident may affect immigration determinations about your residence permit.

What else to know

U.S.–Ukrainian dual citizens: the Tax Code denies the foreign tax credit. The Tax Code provides that a citizen of Ukraine who also holds another citizenship is treated, for personal income tax purposes, as a citizen of Ukraine who has no right to credit tax paid abroad under the Code or under Ukraine's international treaties. Read literally, this would deny a credit for U.S. tax even though Article 24 of the Convention requires one, and treaties take priority over the Tax Code (p. 3.2 TCU; Supreme Court case 160/1061/19). We found no court decision resolving this conflict for a U.S.–Ukrainian dual citizen; seek an individual tax ruling before relying on a credit.
Crediting U.S. tax in Ukraine: you need a certificate of U.S. tax paid. As a Ukrainian resident you report all foreign income in the annual return (due 1 May of the following year; tax payable by 1 August). U.S. tax can be credited only because a treaty is in force (Article 24), only up to the Ukrainian tax on that income, and only if you obtain from the U.S. tax authority a document showing the tax paid and the tax base, legalised (apostilled) unless a treaty provides otherwise. If the document is not yet available, the State Tax Service says the credit can be claimed later, up to 31 December of the following year. We found no official Ukrainian guidance on which IRS document is accepted as such a certificate.
Ukrainian military levy: rate and treaty status. On top of 18% personal income tax, Ukrainian residents pay a 5% military levy on most income, including foreign income (rate in force since 1 December 2024). The Convention covers the Ukrainian income tax on citizens, foreign citizens and stateless persons and «substantially similar taxes» introduced after 4 March 1994. We found no official Ukrainian or U.S. position on whether the military levy is a covered tax, whether Ukraine allows U.S. tax to be credited against it, or whether it is creditable in the United States.
Ukrainian single tax (FOP) and the U.S. foreign tax credit. A registered individual entrepreneur (FOP) may opt for the simplified system. Group 3 pays single tax of 5% of turnover (3% if registered for VAT), plus a military levy of 1% of income and the unified social contribution (ЄСВ). Because the single tax is levied on gross income without deduction of costs, under U.S. regulations a tax on gross receipts generally fails the cost-recovery requirement and is not a creditable foreign income tax; a levy can still be creditable if a treaty treats it as an income tax in its relief article. The single tax is not named in Article 2 of the Convention (it did not exist in 1994), and we found no IRS or Treasury position that it is a «substantially similar tax». IRS Notices 2023-55 and 2023-80 let taxpayers temporarily apply the pre-2022 rules; their effect on the single tax has not been analysed here. Expect that the single tax may not be creditable in the United States — discuss the foreign earned income exclusion with your U.S. adviser.
No U.S.–Ukraine social security (totalization) agreement. The United States has no totalization agreement with Ukraine, so neither country's social security contributions are waived by treaty. A self-employed American in Ukraine (FOP) pays the Ukrainian unified social contribution (ЄСВ); U.S. self-employment tax is covered in the U.S. section.
Social security benefits: taxed only by the paying country — even for U.S. citizens. Social security benefits and other public pensions (other than for past employment) paid by one country may be taxed only in that country. This rule is an exception to the saving clause, so it also protects U.S. citizens: U.S. Social Security benefits of a Ukrainian resident are taxable only in the United States, and a Ukrainian state pension of a U.S. citizen is taxable only in Ukraine.
Working in Ukraine as a non-resident: 183-day rule. If you are not a Ukrainian resident (or the tie-breaker makes you a U.S. resident), salary for work done in Ukraine is taxable only in the United States if you are present in Ukraine for no more than 183 days in the taxable year, the employer is not a Ukrainian resident, and the pay is not borne by a permanent establishment or fixed base in Ukraine. Self-employed income is taxable in Ukraine only if attributable to a fixed base regularly available to you there.
Proving residence: Ukrainian and U.S. certificates. To claim treaty benefits in Ukraine as a U.S. resident you need a U.S. residency certificate (IRS Form 6166, requested on Form 8802), apostilled and translated, covering the period in which the income was paid. A Ukrainian resident (including an FOP) can obtain a certificate of Ukrainian tax residence from the State Tax Service, also for past years. Ukrainian courts will not declare you a non-resident in a stand-alone case — status is decided only in a concrete dispute with the tax authority (see legal positions).

How dual residence is resolved

If both countries treat you as a resident, Art. 4(2) of the treaty applies: Convention between the Government of the United States of America and the Government of Ukraine for the avoidance of double taxation and the prevention of fiscal evasion with respect to taxes on income and capital (signed 4 March 1994). The tests are applied in order — permanent home, center of vital interests, habitual abode, nationality, and finally mutual agreement between the tax authorities. U.S. citizens remain taxable in the United States under the saving clause.

Terms you will come across in Ukraine

ДПС (DPS): State Tax Service of Ukraine

Questions

I am a U.S. citizen — do I still pay U.S. tax if I live in Ukraine?

Yes. The United States taxes its citizens on worldwide income wherever they live, and the treaty keeps that right through the saving clause (Art. 1(3)). You file Form 1040 every year; double taxation is relieved mainly by the foreign tax credit (Form 1116) or the foreign earned income exclusion (Form 2555), plus the treaty's relief article (Art. 24).

Which treaty applies between the U.S. and Ukraine?

The Convention signed on 4 March 1994 (in force 5 June 2000). The tie-breaker is in Art. 4(2): permanent home, center of vital interests, habitual abode, citizenship, then mutual agreement.

What taxes does a resident of Ukraine pay?

Personal income tax at 18% and the military levy at 5% on worldwide income, declared by 1 May of the following year. Foreign tax is credited only with a certificate from the foreign tax authority. U.S.–Ukrainian dual citizens are, under the Tax Code, denied the foreign tax credit — a rule that conflicts with Art. 24 of the treaty.
