Settling losses from cryptocurrencies in PIT-38 – how to do it for the year 2025.


For several years, losses on cryptocurrencies can be settled in the PIT-38 declaration and can reduce the tax on future profits. 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, a loss from the disposal of virtual currencies (i.e., cryptocurrencies) constitutes a cost of acquiring income and can be settled with 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 PIT-38 for the year 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 tax return for the year 2025 (submitted by April 30, 2026), the loss is entered in two places:

  1. Part E – 'Loss from previous years'
    → line 'Losses from the sale 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 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 losses = 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.

  • Loss does not transfer to the spouse in joint filing – each person offsets their loss separately. Example filling (2025).

    Most common mistakes

    • Entering cryptocurrency losses 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 a 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 taxes in the years when you finally make a profit. It is worth keeping accurate records of all transactions (preferably in software like KryptoSkarbiec, CoinTracker, or Koinly), because without it, it's very easy to make a mistake in the settlement.
