Stock tax in Poland

Profits from selling shares and ETFs are taxed at 19% under PIT-38. FIFO is mandatory. Long-term vs short-term – Poland has no holding-period preference; all capital gains are treated the same.

Polish vs foreign shares — the differences that matter

The tax is the same, 19%, but settling foreign shares takes extra steps: converting currencies at NBP rates from day T-1 (Art. 11a), filing PIT-ZG as an attachment to PIT-38, and using the settlement date T+2 rather than the trade date. The calculator does all three automatically.
