Offsetting losses from cryptocurrencies in PIT-38 – how to do it in 2025


For several years now, losses on cryptocurrencies can be offset in the PIT-38 declaration and reduce future profit taxes. This is one of the biggest changes introduced in 2019 and still applicable in 2025.


Can the loss from cryptocurrencies really be deducted?


Yes. According to Article 22, paragraph 1 of the PIT Act, the loss from the disposal of virtual currencies (i.e., cryptocurrencies) constitutes a cost of acquiring income and can be offset against income from the same source within the next 5 tax years.


Example:
In 2024, you had a loss of 30,000 PLN on cryptocurrencies, and in 2025, you achieved a profit of 50,000 PLN.
In the PIT-38 for 2025, you can deduct the entire loss from 2024 → you will only pay tax on 20,000 PLN (50,000 – 30,000).


Where to enter the loss in PIT-38?


In the PIT-38 declaration for 2025 (submitted by April 30, 2026), we enter the loss in two places:

  1. Part E – “Losses from previous years”
    → line “Losses from the disposal of virtual currencies from 2019–2024”
    Here you enter the amount of loss from previous years (up to the amount of income in that year).

  2. Part F – calculation of income
    The system will automatically reduce the income by the loss from part E.

The most important rules 2025

  • You can only offset the loss within the same source (i.e., only cryptocurrencies with cryptocurrencies – not with stocks or real estate).

  • The period for offsetting the loss = 5 consecutive years following the year in which the loss occurred.

  • You do not deduct the loss if you had no income from cryptocurrencies in that year.

  • The loss does not pass to the spouse in joint filing – each one offsets their loss separately. Example filling (2025).

    Most common mistakes

    • Entering the loss from cryptocurrencies in PIT-36 instead of PIT-38 – it will not be deducted

    • Forgetting about the PIT/ZG attachment for transactions with foreign exchanges (if there was foreign withholding tax).

    • Thinking that the loss can be deducted from income from work – it cannot.

    Summary: a loss on crypto is not the end of the world – thanks to the possibility of offsetting it over 5 years, you can realistically reduce your tax in the years when you finally come out ahead. It is worth keeping an accurate record of all transactions (preferably in software like KryptoSkarbiec, CoinTracker, or Koinly), as it is very easy to make mistakes in the settlement without it.
