Tax residency — how to determine where you pay PIT

The Polish rules

You are a Polish tax resident if you meet at least one of two conditions:

you have a centre of personal or economic interests in Poland,
you spend more than 183 days in Poland in a calendar year.

A Polish resident pays PIT on worldwide income — including foreign income.

What "centre of interests" means

It's broader than your registered address. It looks at:

where the family lives (spouse, children),
where you have an apartment/house (owned, not hotel-based),
where you work permanently,
where your bank accounts, insurance, car are,
where you spend free time, where your doctor and dentist are.

The hardest cases: people working remotely from PL with family abroad. Or vice versa.

Conflict of residency — what decides

When both states claim you as resident, the double-tax treaty kicks in. Tie-breaker rules (in order):

Permanent home.
Centre of vital interests.
Habitual abode.
Citizenship.
Mutual agreement between authorities (rare).

Most treaties resolve at level 1 or 2.

Practical scenarios

Pole working in the Netherlands with family in PL: typically a Polish resident (family in PL = centre of interests), but NL income is taxed there too. The treaty sets the avoidance method (usually exemption with progression).

Pole on a UAE contract with no family in PL: typically NOT a PL resident once over 183 days abroad and with no PL property. Pays PIT where they live.

Foreigner living in PL >183 days: Polish resident. Pays PIT on worldwide income in PL.

Common mistakes

Filing for Polish residency when actually living abroad — not allowed, and the tax office checks.
Failing to update residency status after moving.
Not declaring foreign assets to the tax office (form ORD-IN) — penalty up to 10% of value.

Residency certificate

To prove to a foreign authority that you are a Polish resident, you need a residency certificate from the Polish tax office. Issued on request, within 30 days.
