How to File Your PIT Tax Return in Poland 2026 — Step by Step

How to File Your PIT Tax Return in Poland — 2026 Guide

Every Polish tax resident must file an annual PIT (Personal Income Tax) return by April 30th. Whether you're an employee, freelancer, or expat — this guide walks you through the entire process.

Who Needs to File?

You must file a PIT return if you:

• Were a Polish tax resident in the previous year (spent 183+ days in Poland or had your center of life interests here)
• Earned income in Poland from any source
• Are a non-resident who earned Polish-source income

Exception: If you only earned employment income (UoP) and have no deductions to claim, the tax office auto-generates your return via Twoj e-PIT. If you don't modify it by April 30, it's automatically submitted with default settings.

Step 1: Determine Your PIT Form

PIT-37 (Most Common)

For employees and contractors earning income through Polish employers/payers who withhold tax.

• Employment income (UoP)
• Civil law contracts (umowa zlecenie, umowa o dzielo)
• Pensions and retirement benefits

PIT-36

For self-employed (JDG), those with foreign income, or multiple income sources taxed on the progressive scale.

• Business income (JDG on skala podatkowa)
• Foreign income
• Rental income (if using progressive scale)

PIT-36L

For self-employed using the 19% flat tax (podatek liniowy).

PIT-28

For those using ryczalt (lump-sum taxation).

• Must be filed by the end of February (earlier deadline!)

PIT-38

For capital gains — stock sales, ETF profits, crypto gains.

• Due April 30

PIT-39

For real estate sale profits.

Step 2: Gather Your Documents

Before filing, collect:

• PIT-11 from each employer/payer (received by end of February)
• PIT-8C for investment income (from brokers)
• Receipts for deductions (donations, rehabilitation, internet)
• IKE/IKZE contribution confirmations
• Foreign income documents (if applicable)

Step 3: Use Twoj e-PIT

Since 2019, Poland offers Twoj e-PIT — an online system that pre-fills your tax return based on data reported by your employers and institutions.

How to access:

1. Go to podatki.gov.pl
2. Log in via Profil Zaufany, e-dowod, or banking login
3. Review the pre-filled return
4. Add deductions (ulgi) the system doesn't know about
5. Submit electronically

What Twoj e-PIT knows:

• Your employment income (from PIT-11)
• ZUS contributions
• Health insurance contributions
• Number of children (for child tax credit)

What you must add manually:

• Charitable donations (darowizny)
• Internet expense deduction
• Rehabilitation expenses
• Foreign income
• Additional income sources not reported by payers

Step 4: Apply Deductions

Key deductions available in 2026:

Ulga prorodzinna (Child Tax Credit)

• 1 child: 1,112.04 PLN/year (income limit: 112,000 PLN joint or 56,000 PLN single)
• 2 children: 2,224.08 PLN/year
• 3+ children: additional 2,000.04 PLN per child from the third

Ulga na internet (Internet Deduction)

• Up to 760 PLN/year
• Only available for 2 consecutive years (ever)
• Must have receipts/invoices

Ulga rehabilitacyjna (Rehabilitation)

• For disabled persons or their caregivers
• Covers medical expenses, transport, equipment

IKZE Contributions

• Deductible from income (up to annual IKZE limit)
• In 2026: up to ~9,388.80 PLN for employees

Charitable Donations

• Up to 6% of income for donations to qualified organizations

Step 5: Submit and Pay

• Deadline: April 30 (for PIT-37, PIT-36, PIT-36L, PIT-38, PIT-39)
• PIT-28 deadline: End of February
• Payment: If you owe tax, pay by the filing deadline
• Refund: Typically received within 45 days of electronic filing (up to 3 months for paper)

Common Mistakes to Avoid

1. Forgetting to add deductions — Twoj e-PIT doesn't auto-apply all eligible deductions
2. Missing foreign income — Poland taxes worldwide income; report everything
3. Wrong form — Using PIT-37 when you should use PIT-36 (e.g., foreign income)
4. Missing the PIT-28 deadline — It's end of February, not April
5. Not filing PIT-38 — Selling stocks or crypto? You need a separate PIT-38 even if your broker is Polish

FAQ

What happens if I miss the April 30 deadline?

Late filing incurs penalties. If you file late but owe no additional tax, penalties are typically minimal. If you owe tax and file late, you'll face interest charges and potential fines from the tax office (Urzad Skarbowy).

Can I file jointly with my spouse?

Yes. Joint filing (wspolne rozliczenie malzonkow) can be beneficial if one spouse earns significantly more than the other, as it effectively doubles the tax brackets.

Do I need to file if I only have investment income?

Yes. Capital gains from stocks, ETFs, or crypto require a PIT-38 filing even if your broker withheld tax. Check your PIT-8C from your broker.

Can expats use Twoj e-PIT?

Yes, if you have a Polish tax identification number (NIP or PESEL for tax purposes) and can log in via Profil Zaufany or banking authentication.
