Frequently Asked Questions

Which NBP exchange rate should I use for my PIT tax return?
  • ·Under Art.
  • ·11a of the Polish PIT Act, foreign income must be converted to PLN using the NBP mid-rate from the last business day before the date the income was received (payment date).
  • ·This tool automatically finds that rate for you.
Why does the tool subtract one day from my payment date?

Polish tax law requires the exchange rate from the day before the payment date, not the payment date itself. If that day falls on a weekend or public holiday (when NBP does not publish rates), the tool keeps going back until it finds the last published rate.

Where does the exchange rate data come from?
  • ·All rates come directly from the official National Bank of Poland (NBP) API.
  • ·The tool uses Table A mid-rates, which are the rates required for PIT reporting.
  • ·No third-party data sources are involved.
Which currencies are supported?

Currently USD (US Dollar), EUR (Euro), and GBP (British Pound) — the most common currencies for Polish remote workers and freelancers earning foreign income. These cover the vast majority of PIT conversion needs.

Can I use this for B2B invoices / VAT reporting?
  • ·This tool is designed specifically for PIT (personal income tax) reporting where you need the rate from the day before payment.
  • ·VAT invoices may use different date rules (e.g., the day before the invoice date).
  • ·Always verify the correct date rule for your specific tax obligation.
