PIT Inwestora is a Polish tax reporting application for retail investors who hold accounts with foreign brokers — and it exists because of a specific gap in the Polish system. A domestic brokerage issues its clients a PIT-8C form each year, listing their capital gains and deductible costs, which makes filing the annual PIT-38 return relatively painless. Interactive Brokers issues nothing of the sort. Every Polish investor with a foreign brokerage account is left to reconstruct the whole calculation themselves.
That reconstruction is heavier than it sounds. Each transaction must be converted into złoty at the National Bank of Poland rate from the day before it settled. Cost basis has to be established under FIFO. Dividends and interest need separating and attributing to the country they came from, in order to complete the PIT/ZG foreign income attachment. Any withholding tax already paid abroad has to be evidenced. Get any of it wrong and you either overpay or file an incorrect return.
PIT Inwestora automates that chain. A user uploads their IBKR activity statements — alongside any PIT-8C from a Polish broker, R-185 withholding documents, and supporting files — into a single case folder. The application identifies the tax years, accounts, and transactions it finds, applies FIFO and NBP conversion, flags discrepancies that need human review, and produces the figures required for PIT-38 and PIT/ZG. Crucially, it shows the methodology and evidence beside each number rather than burying them under a total, and it can combine a Polish PIT-8C with a foreign IBKR statement in the same annual result — which is the position most Polish investors with international exposure actually find themselves in.
The product is paired with a library of guides covering PIT-38 filing step by step, IBKR-specific reporting, when PIT/ZG becomes relevant, and the two most common sources of error: FIFO and the NBP exchange rate. It occupies a niche the large European tax platforms have largely left alone — not tax filing in general, but the particular mechanics of reporting a foreign brokerage account under Polish law.
Most Poles still navigate PIT filing through complex government portals or hire accountants to handle the bureaucracy. Pit in Westora inverts that equation, giving users control over their own returns with guided workflows that walk through each deduction, income source, and credit without requiring specialist knowledge. The platform connects directly to bank data and accounting records, pulling information automatically to pre-populate forms.
For a market where tax compliance remains largely analog despite digital infrastructure, Pit in Westora represents a quiet but meaningful shift toward consumer financial empowerment. It positions itself as the bridge between personal finance tools and formal regulatory requirements—neither a bank nor a full accounting suite, but the missing piece that connects them.
The company operates in Poland's growing personal finance tech segment, where digitization of tax services remains incomplete compared to Western European counterparts. By focusing on one clear pain point rather than attempting to be an all-in-one financial platform, Pit in Westora demonstrates the European fintech pattern of hyper-specialization around regulatory compliance.
