Legal Classification of Cryptocurrency in Poland
Under Polish law, cryptocurrency is classified as virtual currency (waluta wirtualna) pursuant to the Act on Combating Money Laundering and Terrorist Financing (ustawa AML). For tax purposes, income from virtual currencies falls under a specific category in the Personal Income Tax Act (ustawa o PIT), separate from capital gains on shares or bonds.
This classification has important implications. Crypto income is taxed under Article 17(1)(11) of the PIT Act as income from "the exchange of virtual currency for means of payment, goods or services, property rights other than virtual currency, or claims." This broad definition captures the full range of disposals — selling for PLN, swapping for another coin, or paying for a product.
The 19% Flat Capital Gains Tax
All taxable income from virtual currencies is subject to a flat 19% tax rate (podatek od zysków kapitałowych). This rate applies regardless of:
- How long you held the cryptocurrency before disposing of it (no long-term exemption)
- The size of the gain (no progressive scale — it is flat at 19% from the first zloty)
- Whether the gain is from spot trading, DeFi, or NFTs
There is no annual tax-free allowance for crypto income in Poland. Every profitable disposal is in principle taxable.
What Counts as a Taxable Event in Poland
The following activities trigger a taxable event under Polish law:
- Selling cryptocurrency for Polish zloty (PLN) or any other fiat currency (EUR, USD, GBP, etc.)
- Exchanging one cryptocurrency for another (e.g. BTC to ETH) — this is explicitly taxable in Poland, unlike France and Portugal where crypto-to-crypto swaps are not taxed
- Paying for goods or services with cryptocurrency
- Using cryptocurrency to acquire other property rights (non-virtual currency)
Non-Taxable Events in Poland
- Buying cryptocurrency with fiat. Purchasing Bitcoin with PLN is not a taxable event — it establishes your cost basis.
- Transferring cryptocurrency between your own wallets. Moving assets between addresses you control does not trigger tax.
- Receiving cryptocurrency as a gift — though gift tax rules (podatek od spadków i darowizn) may apply separately above certain thresholds.
- Holding cryptocurrency. Unrealised gains are not taxed.
Calculating Taxable Income
Taxable income from virtual currencies is calculated as:
Income = Proceeds − Allowable Costs
Allowable costs include:
- The original purchase price of the cryptocurrency you are disposing of
- Exchange fees and transaction costs paid when acquiring the cryptocurrency
- Exchange fees paid at the time of the disposal
Poland uses the FIFO method (first in, first out) for calculating which tokens are being sold when you have multiple purchases of the same asset at different prices. Some accountants apply weighted average, but FIFO is the safer and more widely accepted approach.
Crypto-to-Crypto Swaps: A Key Polish Specificity
This is one of the most important distinctions between Poland and some other EU countries. In Poland, exchanging one cryptocurrency for another (e.g. selling Bitcoin to buy Ethereum) is a fully taxable disposal of the first asset.
Practically, this means you need to calculate and record a gain or loss every time you trade between coins — not just when you cash out to PLN. This significantly increases record-keeping requirements for active traders.
Example: You buy 1 BTC for PLN 150,000. You later swap it for ETH when BTC is worth PLN 200,000. The PLN 50,000 gain is taxable at 19%, meaning a PLN 9,500 tax liability — even though you never received any zloty.
Mining Income
Mining cryptocurrency is treated differently from investing. Mining income is generally classified as income from a non-agricultural business activity (pozarolnicza działalność gospodarcza) or as "other sources" of income, depending on the scale and organisation of the activity.
For occasional or small-scale mining, the Ministry of Finance has indicated this may be treated as income from other sources, taxed at progressive PIT rates (12% up to the first threshold, 32% above). For systematic, business-scale mining, it is business income subject to either progressive or the flat 19% business tax (liniowy PIT), depending on which the taxpayer has elected.
Staking and DeFi Rewards
Poland does not have specific legislation for staking rewards or DeFi income as of 2025. The prevailing interpretation among Polish tax advisors is that:
- Staking rewards received as new tokens are taxable as income under "other sources" (inne przychody) at the time of receipt at fair market value.
- DeFi yield and interest income is similarly treated as income when received.
- When the received tokens are later disposed of, any further gain is subject to the standard 19% virtual currency tax.
This is an area where Polish tax law is still developing. It is advisable to consult a tax advisor if you have significant staking or DeFi income.
Loss Carryforward
If your total allowable costs exceed your proceeds in a given tax year (i.e. you made a net loss), you can carry that loss forward for up to five consecutive tax years. The loss can only be offset against income from virtual currencies in future years — not against other types of income such as employment income or dividends.
Regulatory Oversight in Poland
The Polish Financial Supervision Authority (Komisja Nadzoru Finansowego, or KNF) oversees crypto asset service providers (CASPs) under the AML Act. Poland implemented MiCA requirements as part of its EU obligations. Crypto exchanges and wallet providers operating in Poland must register with the KNF and comply with AML/KYC requirements.
Poland''s KAS (Krajowa Administracja Skarbowa, the national tax administration) has been actively cross-referencing exchange data with PIT filings. Failing to report crypto income is a significant compliance risk.
Key Takeaways
- Poland taxes all crypto capital gains at a flat 19% rate.
- Crypto-to-crypto swaps are taxable events — you must calculate gain or loss on every trade.
- There is no annual exemption and no long-term holding benefit.
- Losses can be carried forward for five years but only against crypto income.
- Report on PIT-38 by April 30 each year.
