Is Poland's 183-day rule rolling or calendar year?

Calendar year. Poland measures the 183 days within a single tax year, which runs from 1 January to 31 December, and assesses each calendar year on its own. A stay split across two calendar years is counted separately in each year.

Can you be a Polish tax resident with fewer than 184 days?

Yes. Poland can also treat you as resident if your centre of personal or economic interests, your centre of vital interests, is in Poland. Either test alone is enough, so you can be resident even without spending more than 183 days there.

Poland's 183-Day Tax Residency Rule

Q: How many days can you stay in Poland without becoming a tax resident?

Up to 183 days in a single calendar year. Exactly 183 days does not make you resident under the day-count test, but staying 184 days or more in one calendar year does. A separate centre-of-vital-interests test can also apply.

More than 183 days in a single calendar year makes you a Polish tax resident. Here is exactly how the count works.

Last verified: July 2026

In short: you become a Polish tax resident if you spend more than 183 days in Poland during a single calendar year. Any part of a day counts, including the day you arrive and the day you leave. A Polish centre of vital interests is a separate route in, even below 184 days.

Threshold: More than 183 days
Counting window: Calendar year
A day counts if: You are present for any part of it
Other residence test: Centre of vital interests
Tax year: Calendar year
Legal basis: PIT Act, Art. 3(1a)

The rule

Poland treats you as a tax resident if you stay in the country for more than 183 days in a tax year. Two points decide most real cases:

The window is the calendar year. The 183 days are counted within a single calendar year, from 1 January to 31 December, not a rolling 12-month period. Each calendar year is assessed on its own, and your presence does not need to be continuous. Check whether your presence exceeded 183 days in any single calendar year.
Any part of a day counts. Poland uses the physical-presence method: every day you are in Poland counts, and any part of a day is enough, so the day you arrive and the day you leave both count. A full day spent outside Poland does not count.

How to count it

List every Poland trip with arrival and departure dates.
Count each day you are physically present, including arrival and departure days, since any part of a day counts.
Total those days within each calendar year separately. A stay that spans two calendar years is split, and each year is counted on its own.
If your presence in any single calendar year exceeds 183 days, the day-count test is met for that year.

Example. Several intermittent stays across 2026 that add up to 190 days in Poland: 70 days in spring, 60 in summer, then 60 in autumn.

The stays are not continuous, but together they total 190 days inside the 2026 calendar year, more than 183, so the day-count test is met for 2026. Note that if those same days had straddled two calendar years, each year would be counted separately, and neither might cross 183.

Beyond the day count

The 183-day count is one route in, not the only one. Poland can also treat you as resident if your centre of personal or economic interests, your centre of vital interests, is in Poland. Personal ties cover things like a spouse and children living there; economic ties cover your main source of income and assets. Either test alone is enough to make you a resident, so you can qualify even without spending more than 183 days there. Residency can also change part-way through a year, giving a split-year outcome. And if another country also claims you, a double-tax treaty decides residency through tie-breaker rules such as permanent home and centre of vital interests.
