PITax review
A free Polish tax filing tool with broad return support and electronic submission.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
PITax is personal tax software for preparing and submitting annual Polish PIT returns. It is aimed at individuals, including people with employment income, business income, private rental income, investment income or cryptocurrency transactions. The product also supports returns for relatives and clients, making it suitable for solo users and small operators handling more than one declaration. Supported forms include PIT-37, PIT-36, PIT-28, PIT-38, PIT-36L and PIT-39, together with related schedules.
Pricing is straightforward: the published plans show one Free plan priced at 0. It includes preparation of Polish PIT declarations, calculation of deductions and tax reliefs, electronic submission and an official receipt known as UPO. There are no paid tiers to compare, so the product’s offer is centered on the free filing workflow rather than tiered access. PITax is available through a web browser, Windows application and Android mobile app. Its government-service connections include e-Deklaracje and e-Urząd Skarbowy, including data import from Twój e-PIT.
The main strength is breadth within Polish personal tax filing. Automatic calculation and validation can help users check declaration data, while guidance on reliefs and deductions supports the preparation process. Users can also correct previously submitted returns and access archived returns after filing. Support channels include email, chat, phone and documentation, with 24/7 support listed. Its focus is also its boundary: PITax is built around Poland’s national PIT system rather than state filing workflows. Choose it if you need free Polish return preparation with electronic submission and broad income coverage. It is less suitable for filing outside Poland or for buyers seeking multiple paid service levels.
