Poland Tax Guide for Expats 2026

Moving to Poland — or working remotely from Warsaw/Kraków/Wrocław — means dealing with a tax system that looks complex but is predictable once you learn the main forms (PIT-37, PIT-36, PIT-38), two ZUS tracks, and a handful of personal reliefs. This guide covers everything an expat needs for tax year 2025, filed in 2026.

Who this applies to

• Foreign nationals employed by Polish companies.
• EU assignees and digital nomads physically present in Poland.
• B2B freelancers invoicing foreign clients while based in Poland.
• Students and researchers with stipends.
• Retirees relocating to Poland with foreign pensions.

Polish tax residency — the 183-day rule

You're a Polish tax resident if either:

1. You spend more than 183 days in Poland during a tax year, or
2. Your centre of vital interests (family, main home, business) is in Poland.

Residents pay Polish tax on worldwide income. Non-residents pay only on Polish-source income (employment performed in PL, rental of PL property, PL business).

Key 2026 figures

• Progressive scale: 12% up to PLN 120 000, 32% above.
• Tax-free amount: PLN 30 000 (residents only).
• Flat 19% option for business (liniówka).
• Ryczałt (lump-sum on revenue): 3%–17%, depending on activity.
• Belka tax: 19% on capital gains, dividends, interest.
• Health insurance: 9% (employees), 4.9% (flat tax), tiered on ryczałt.
• Social security (ZUS): ~13.71% employee share; employer adds ~20%.
• Abolition relief: PLN 1 360 for foreign income (credit method).
• PIT-0 for under-26: exempt up to PLN 85 528 (also available to foreigners resident in PL).

Step-by-step annual filing

1. Determine residency for the full 2025 tax year.
2. Gather PIT-11s from every Polish employer/contractor by 31 January 2026.
3. Collect foreign income docs (W-2, P60, Lohnsteuerbescheinigung, etc.).
4. Choose the right form:
   • PIT-37 — employment/pension income only, Polish-source.
   • PIT-36 — foreign income, rental on scale, multiple income types.
   • PIT-38 — capital gains, crypto, securities.
   • PIT-36L / PIT-28 — flat tax / ryczałt for JDG.
5. Apply DTT method (exemption with progression or proportional credit) — see PIT/ZG attachment.
6. Claim allowances: child relief, internet, IKZE, donations, thermomodernisation.
7. Submit by 30 April 2026 via Twój e-PIT / e-Deklaracje.
8. Pay any balance by the same deadline to mikrorachunek podatkowy.

Worked example — German expat in Warsaw

Hans — German national, 10 months in Warsaw 2025, employed by Polish tech company.

• Polish salary: PLN 180 000.
• Costs of revenue (zamiejscowe): PLN 3 600.
• ZUS employee share: ~PLN 24 680.
• Tax base: 180 000 − 3 600 − 24 680 = 151 720.
• Scale: 12% × 120 000 + 32% × 31 720 = 14 400 + 10 150 = 24 550 PLN.
• Tax-free amount: −3 600.
• Tax payable: 20 950 PLN.
• Less advance withholdings from monthly payslips → typically small balance owed or small refund.

Hans also keeps an apartment in Munich, rented out — rental income uses exemption with progression (PL–DE treaty), reportable on PIT-36 + PIT/ZG, raising his effective rate slightly.

Common mistakes and pitfalls

• Filing PIT-37 with foreign income — wrong; use PIT-36 + PIT/ZG.
• Misjudging residency — staying <183 days doesn't save you if your family/home is in PL.
• Missing the 20th-of-month advances when income isn't withheld by a Polish payer.
• Forgetting 1.5% donation — small but nice to do.
• Double ZUS — posted workers covered by home country A1 certificate shouldn't pay PL ZUS.
• Ignoring FX conversion rules — NBP average on day before receipt.

e-Urząd Skarbowy and Twój e-PIT

Twój e-PIT (podatki.gov.pl) auto-generates PIT-37 and PIT-38 from 15 February 2026. Log in with trusted profile, mObywatel, or Polish bank login. Foreign nationals can obtain trusted profile through a bank or at the Tax Office. Without action, PIT-37/PIT-38 is auto-accepted on 30 April 2026 — review before then to claim reliefs.

2026 deadlines

• 31 January — PIT-11 delivered by employer.
• 15 February — Twój e-PIT opens.
• 30 April — PIT-37 / PIT-36 / PIT-38 / PIT-28 / PIT-36L filing & payment.
• End of June — deadline for filing foreign certificates of residence when applicable.

FAQ

Do I need a PESEL to file taxes? Yes — you'll need a PESEL or NIP to submit any PIT. EU citizens can get PESEL at their local urząd miasta (city office).

Can I file jointly with my non-Polish spouse? Yes, if both are EU/EEA/Swiss residents and 75% of combined income is taxable in Poland.

How do I pay tax due? Generate your individual microaccount on podatki.gov.pl (it's NIP/PESEL-based) and transfer via Polish bank or international SEPA.

What happens if I move mid-year? Your tax residency may change mid-year. Most treaties define a "split-year" rule — you're resident in PL only from the day you established your centre of interests there.

Are crypto and foreign dividends taxed in Poland as an expat? If you're PL-resident, yes — PIT-38 at 19% Belka, with treaty credits for foreign withholding on dividends.

Social security for expats — key scenarios

• EU posted worker (up to 24 months) — stay on home country social security with A1 certificate. No Polish ZUS.
• EU assignee (employed locally by PL entity) — Polish ZUS applies; totalisation rules (Reg. 883/2004) prevent double contributions.
• Non-EU with totalisation agreement (USA, Canada, Australia, South Korea, etc.) — A1 equivalent prevents dual contributions for up to 5 years.
• Non-EU without agreement — PL ZUS typically required if working in Poland.

Common expat reliefs worth claiming

• PIT-0 for relocators — first 4 years of tax residency after move back to PL (also available to foreign nationals becoming PL residents for the first time). Up to PLN 85 528 income tax-free.
• Family joint filing (for EU/EEA/Swiss married couples).
• Child tax credit — applies regardless of nationality if the child is Polish-resident.
• IKZE — tax-deductible pension contributions (PLN 10 407.60 individual / PLN 15 611.40 self-employed limits 2025).
• Donations to OPP — up to 6% of income (separate from 1.5% allocation of tax).

Avoiding Polish residency pitfalls

If you want to avoid becoming a Polish tax resident:

1. Keep presence under 183 days per year.
2. Retain centre of vital interests abroad (spouse, home, main bank accounts).
3. Hold a foreign tax residency certificate.
4. Use corporate or treaty protection (local payroll via a foreign company).

Grey areas to watch: dual homes, long remote-work stays, mid-year relocation.
