Top 5 Polish PIT tools 2026

1. Twój e-PIT (Ministry of Finance) — the default

Twój e-PIT is the official government service. For 80% of Poles, logging in with Profil Zaufany and accepting the pre-filled return is enough. In 2026 it supports PIT-37, PIT-36, PIT-28 and PIT-38 with automatic broker data import from participating brokers.

4. e-PIT.pl — free online alternative

Taxmaster specializes in foreign investment tax filing. It imports trades from Interactive Brokers, Degiro, XTB, Freedom24, and in 2026 also crypto exchanges (Binance, Kraken). It calculates capital gains tax, dividends and FX differences automatically.

• Pros: best for foreign investors, crypto support, automatic PIT-8C generation
• Cons: narrow specialization, requires some tax knowledge
• 2026 pricing: 49–199 PLN (package with crypto and foreign brokers)
• Best for: equity investors with foreign accounts, crypto traders

Bonus mention: international tools (Taxfix, TurboTax)

Taxfix and similar international apps don't fully support Polish PIT filing yet — they remain strong in Germany, Austria and the US. For expats in Poland with cross-border taxation, use Taxmaster plus a Polish tax advisor.

FAQ

Is Twój e-PIT enough if I have several PIT-11 forms? Yes. The tax office imports all PIT-11 forms submitted by employers. You just verify and accept.

How do I file crypto taxes in 2026? Crypto is reported on PIT-38 (separate from regular stock brokerage). You need a buy/sell summary from your exchange. Taxmaster auto-imports this from Binance, Kraken and others.

When is the Polish PIT deadline? April 30, 2026. PIT-28 (flat-rate), PIT-37, PIT-36, PIT-36L and PIT-38 all share the April 30, 2026 deadline.

Does tax software know all deductions? Good tools (PITax, Format, Taxmaster) walk you through every deduction. Twój e-PIT shows the popular ones — rehabilitation or thermomodernization reliefs must be clicked in manually.

What if I make a mistake? You can file a correction (korekta) in Twój e-PIT or your chosen tool at any time. The tax office doesn't penalize self-initiated corrections.
