Tax residence in Poland for Singapore taxpayers

Poland treats you as resident if your centre of personal or economic interests is in Poland, or if you stay there for more than 183 days in the calendar year — either is enough. Singapore decides your status for the calendar year too, with 183 days or more of presence or employment. If both countries claim you, Art. 4(2) of the Singapore–Poland Agreement decides; salary follows a 183-day rule over any twelve-month period (Art. 15(2)), and income from Poland is generally exempt in Singapore.

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 Singapore: 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 non-resident

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 Singapore tax rules

Collision: centre of interests in Poland while resident in Singapore. Poland treats you as resident because your personal or economic centre is in Poland — either one is enough — while Singapore treats you as resident through 183 days of presence or employment, normal residence as a citizen or Permanent Resident, or IRAS's two- or three-year rules. Art. 4(2) of the Singapore–Poland Agreement decides: permanent home; with a home in both countries, centre of vital interests (personal and economic ties together); if that cannot be determined, or you have a permanent home in neither, habitual abode; then nationality; in any other case, mutual agreement.
Collision: more than 183 days in Poland while still resident in Singapore. Poland treats you as resident because of the length of your stay alone. Singapore can treat you as resident for the same calendar year on other grounds — as a citizen or Permanent Resident who normally lives in Singapore and is abroad only temporarily, or under IRAS's two- or three-year rules in the year you leave. Under Art. 4(2) of the Agreement a permanent home available only in Singapore still makes you a resident of Singapore for the treaty; Poland can then tax only Polish-source income, such as pay for work in Poland beyond the limits of Art. 15(2).

What else to know

Calendar year in both countries — but a rolling 12-month period for salary. Singapore decides your residence for the calendar year (the basis period for the following Year of Assessment) and Poland for its tax year, which is also the calendar year. The tests differ: Singapore needs 183 days or more of presence or employment in the year (or normal residence as a citizen or Permanent Resident, or IRAS's two- and three-year rules), Poland more than 183 days, or a centre of personal or economic interests in Poland whatever the days. The 183-day test for salary in Art. 15(2)(a) of the Singapore–Poland Agreement is different again: any twelve month period commencing or ending in the fiscal year concerned. Check every 12-month window that touches the year, not just the calendar year.
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.
Working in Poland while resident in Singapore: 183 days in any 12 months (Art. 15(2)). Pay for work physically performed in Poland — including remote work for a Singapore employer — is Polish-source income. If Singapore is your treaty residence, Poland does not tax it only if all three conditions of Art. 15(2) are met: not more than 183 days in Poland in any twelve month period commencing or ending in the fiscal year concerned, pay from an employer who is not resident in Poland, and pay not borne by a permanent establishment or fixed base the employer has in Poland. Otherwise Poland taxes the pay for Polish work days. In Singapore such pay is foreign-sourced income, generally exempt for a resident individual (s. 13(7A)); where Singapore does tax it — for example if the work abroad is incidental to a Singapore employment — the Polish tax is credited (Art. 22(2)(a)).
How Singapore and Poland relieve double taxation. If Singapore is your state of residence, income from Poland is generally not taxed in Singapore: the Agreement itself provides that Singapore exempts it where the conditions of the Income Tax Act for exempting income received from outside Singapore are met (Art. 22(2)(b); s. 13(7A)). Where Singapore does tax it, the Polish tax is credited against the Singapore tax on that income (Art. 22(2)(a)) — claim the foreign tax credit in your Singapore return. Because Singapore exempts such income, the limitation-of-relief clause does not cut down Polish treaty relief on it (Art. 27(2)(b)). If Poland is your state of residence, Poland deducts the income tax paid in Singapore, up to the Polish tax attributable to that income (Art. 22(1)(a); proportional credit under art. 27 ust. 9 of the PIT Act).
Year of the move: Poland can split its year, Singapore does not. Poland treats you as resident from the date your centre of interests moves (for example, when your family moves), so the Polish year can be split. Singapore has no split year: your status is decided for the whole calendar year, although IRAS's two- and three-year rules can make a short first or last year a resident year. Where both countries treat you as resident for the same period, the Agreement decides for that period.
Ulga na powrót — only with 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 previously lived in one of the listed countries for at least three years. It is available only to Polish citizens, Karta Polaka holders or EU/EEA/Swiss citizens — not to someone who holds only Singapore citizenship. Check whether Singapore is among the listed countries of prior residence before relying on the relief.

How dual residence is resolved

If both countries treat you as a resident, Art. 4(2) of the treaty applies: Agreement between the Government of the Republic of Singapore and the Government of the Republic of Poland for the Avoidance of Double Taxation and the Prevention of Fiscal Evasion with respect to Taxes on Income, with Protocol, signed at Singapore on 4 November 2012 (Poland: Dz.U. 2014 poz. 443), as modified by the MLI. The tests are applied in order — permanent home, centre of vital interests, habitual abode, nationality, and finally mutual agreement between the tax authorities.

Questions

Is 183 days in Poland enough to become resident?

No — Poland requires more than 183 days in the tax year (from day 184), counting every part of a day. A centre of personal or economic interests in Poland makes you resident regardless of days. Singapore, by contrast, counts 183 days or more.

How are the 183 days for salary counted under the Agreement?

Art. 15(2)(a) of the Singapore–Poland Agreement counts days in any twelve month period commencing or ending in the fiscal year concerned — a rolling period, not only the calendar year.

Is my Polish income taxed in Singapore if I stay resident there?

Generally not: foreign-sourced income received by a resident individual is exempt (s. 13(7A)), and Art. 22(2)(b) of the Agreement provides for that exemption. Where Singapore does tax it, the Polish tax is credited (Art. 22(2)(a)).
