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

Poland treats you as a tax resident if your center of personal or economic interests is in Poland or you stay there more than 183 days in the tax year — either test is enough. U.S. citizens remain taxable in the United States; the U.S.–Poland treaty settles dual residence.

When Poland treats you as a tax resident

In Poland the criteria are alternative: a personal or merely an economic centre in Poland, or a stay of more than 183 days, is enough.

Your centre of vital interests is in Poland — under art. 3 ust. 1a of the PIT Act you are a Polish tax resident, taxable on worldwide income.
Your centre of economic interests is in Poland — under Polish law this alone is enough, even if your family lives in the U.S.: you are a Polish tax resident.
You stayed in Poland for more than 183 days in the tax year — under art. 3 ust. 1a pkt 2 of the PIT Act you are a Polish tax resident; your visa or residence permit type does not matter.

When you are a nonresident

No centre of interests in Poland and a stay of 183 days or fewer — you are not a Polish tax resident. Polish-source income (including pay for work performed in Poland) is still taxable there.

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

Collision: centre of interests in Poland while the U.S. taxes you as citizen or resident. Poland treats you as resident because your personal or economic centre is in Poland; the United States taxes you on worldwide income as a citizen, green-card holder or substantial-presence resident. If you are resident in both countries, Art. 4 of the 1974 Convention decides: permanent home → centre of vital interests (also when you have a home in neither country) → habitual abode → citizenship. Whatever the result, the U.S. keeps taxing its citizens under the saving clause (Art. 5(3)); Poland credits U.S. tax and the U.S. credits Polish tax (Art. 20).
Collision: more than 183 days in Poland while the U.S. also treats you as resident or citizen. Poland treats you as resident because of the length of your stay alone; the U.S. taxes you as a citizen or U.S. resident. Under the 1974 Convention a permanent home available only in the U.S. still makes you a U.S. resident for treaty purposes (Art. 4(a)) — but a U.S. citizen remains taxable in the U.S. in any case (Art. 5(3)), and pay for work done in Poland during a stay of more than 183 days in the tax year is taxable in Poland (Art. 16).

What else to know

1974 treaty: a U.S. citizen living abroad may not be a «U.S. resident» at all. The 1974 Convention defines a U.S. resident as a person resident in the United States for U.S. tax purposes (Art. 3(1)(h)); unlike modern U.S. treaties it does not list citizenship. Art. 4 applies only to persons resident in both States. If you are a U.S. citizen without a green card who lives in Poland and does not reside in the U.S., the treaty most likely treats you simply as a resident of Poland — the outcome is the same as under the tie-breaker. The U.S. still taxes you as a citizen (Art. 5(3)).
Relief from double taxation under the 1974 treaty. As a Polish resident you get a Polish credit for U.S. tax (Art. 20(1), proportional credit under art. 27 ust. 9 of the PIT Act). The U.S. gives its citizens and residents a credit for Polish tax (Art. 20(2)). Unlike the U.S.–Spain or newer U.S. treaties, the 1974 treaty has no re-sourcing rule for U.S. citizens resident in Poland, so double tax on U.S.-source income that the U.S. taxes only because of citizenship may not be fully relieved — check the U.S. foreign tax credit and exclusion rules (covered in the U.S. section).
Exactly 183 days: not yet resident in Poland. The PIT Act requires more than 183 days in the tax year (from day 184). Poland counts every part of a day, including days of arrival and departure; the stay need not be continuous.
Pay for work in Poland is taxed in Poland. Even if you are not a Polish resident (or are a U.S. resident under the treaty), pay for work physically performed in Poland — including remote work for a U.S. employer — is taxable in Poland unless all conditions of Art. 16 of the 1974 Convention are met: not more than 183 days in Poland in the tax year, an employer not resident in Poland, and pay not borne by a Polish permanent establishment of the employer.
Year of the move: Poland recognises a change of residence during the year. Poland treats you as resident from the date your centre of interests moves (for example, when your family moves), so the year can be split; U.S. citizens remain taxable in the U.S. for the whole year. Match the periods so the same income is not taxed twice without a credit.
Ulga na powrót — only if you also hold Polish or EU citizenship or a Karta Polaka. Poland exempts employment and business income up to PLN 85,528 a year for four years for people who move their residence to Poland after three calendar years of non-residence and who lived abroad (the USA is on the list) for at least three years. It is available only to Polish citizens, Karta Polaka holders or EU/EEA/Swiss citizens — so a U.S. citizen qualifies only with such a second status. The U.S. still taxes the exempt income; with no Polish tax paid there is no Polish tax to credit.
Social security: U.S.–Poland totalization agreement. The U.S.–Poland social security agreement (signed 1 April 2008, in force 1 March 2009) assigns social-security coverage to one country, so you generally do not pay U.S. and Polish contributions on the same work. Ask the system that covers you for a certificate of coverage before payroll starts.
Which treaty applies: still the 1974 Convention. The U.S.–Poland income tax Convention of 8 October 1974 is still in force. A new Convention signed on 13 February 2013 was ratified by Poland but never received U.S. Senate advice and consent (last Senate action: 3 January 2017), so it does not apply. Residence tie-breaker: Art. 4 (no mutual-agreement step for dual citizens); saving clause: Art. 5(3); employment: Art. 16 (183 days in the tax year); relief: Art. 20 (credit both ways); mutual agreement: Art. 22.

How dual residence is resolved

If both countries treat you as a resident, Art. 4 of the treaty applies: Convention between the Government of the United States of America and the Government of the Polish People's Republic for the avoidance of double taxation and the prevention of fiscal evasion with respect to taxes on income (signed 8 October 1974). 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.

Questions

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

Yes. The United States taxes its citizens on worldwide income wherever they live, and the treaty keeps that right through the saving clause (Art. 5(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. 20).

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

The Convention signed on 8 October 1974 remains in force. The new treaty signed on 13 February 2013 has not entered into force — the U.S. Senate never gave consent. The 1974 treaty's residence article has no mutual agreement step of its own.

When do I become a Polish tax resident?

When your center of personal or economic interests is in Poland or you stay more than 183 days in the tax year — either test is enough. Under Art. 16 of the 1974 treaty Poland can tax salary for work there if you exceed 183 days in the tax year or a Polish employer pays it.
