PIT-38 — form, instructions, downloadable PDF and online filing

What is PIT-38?

PIT-38 is the tax return filed by individuals who realized income from the sale of securities (shares, ETFs, bonds) or received foreign dividends. The current version in force is PIT-38(18) (for tax year 2024 and later). The form covers section C (securities sales), section D (capital gains tax calculation), section G (foreign dividends), section J (optional 1.5% OPP request), and the PIT/ZG attachment for foreign-sourced share income. 1 „Aktualny formularz PIT-38 (18)”3 „podatek dochodowy wynosi 19% uzyskanego dochodu”4 „z dywidend ... pobiera się 19%”

Who files PIT-38?

  • You sold shares, ETFs or other securities outside of a business activity.
  • You invest with a foreign broker (Interactive Brokers, XTB, Trading 212, IBI Capital) and will not receive a PIT-8C — you are responsible for reporting the income yourself.
  • You received foreign dividends — they must be reported in section G, even if the broker withheld tax at source.
  • You realized a capital loss — worth declaring, since it reduces tax in the following 5 years (art. 9 sec. 3 PIT Act).5 „nie może przekroczyć 50% wysokości tej straty”

Deadlines — PIT-38 for 2025 and subsequent years

The filing deadline and tax payment date is April 30 of the year following the tax year. PIT-38 for 2025 must be filed by 30.04.2026. The form is submitted electronically (e-Urząd Skarbowy, e-Deklaracje) or on paper at the competent tax office. 1 „Aktualny formularz PIT-38 (18)”
