Poland Cryptocurrency Tax Guide (Opodatkowanie Kryptowalut)

Cryptocurrency taxation in Poland depends on the taxpayer's status. Private investors pay a flat 19% Belka tax (podatek Belki) on realised capital gains from crypto. Business traders are taxed at progressive IIT rates (12%/32%) on crypto income. The Polish Ministry of Finance (MF) has issued detailed guidance on crypto transactions. Crypto-to-crypto trades are taxable events. Mining is treated as business income. All amounts in PLN.

The Polish tax treatment of cryptocurrencies (waluty wirtualne) is governed by the Personal Income Tax Act (Ustawa o PIT) and interpretative guidance from the Minister of Finance. For related guidance, see our Tax Filing Guide → and Cross-Border Guide →.

Private Investors — 19% Belka Tax

Individuals who trade crypto occasionally and outside a business are taxed at a flat 19% capital gains tax (podatek od zysków kapitałowych, commonly called Belka tax).
Tax is levied on realised gains — the difference between the sale proceeds and the acquisition cost (in PLN). Crypto-to-crypto exchanges (e.g., BTC to ETH) are taxable events — the disposal of one crypto for another triggers a capital gain or loss.
Losses from crypto trading can be offset against other crypto gains in the same tax year, but cannot be offset against other capital gains (e.g., stock market gains) or carried forward.
You report crypto gains on PIT-38 (capital gains return), due by April 30 of the following year. If only crypto transactions occurred, PIT-38 is the sole return needed.

Business Traders — Progressive IIT 12-32%

If crypto trading is conducted in a regular, organised, and profit-seeking manner, it may be classified as business activity (działalność gospodarcza). The tax authority assesses based on frequency, volume, sophistication, and intent.
Income is taxed at progressive PIT rates: 12% up to PLN 120,000, 32% above that threshold (2025-2026 brackets). Alternatively, traders may elect the flat 19% liniowy rate if registered as a sole proprietor.
Business traders can deduct business expenses (trading platforms, hardware, electricity, internet, analytics tools, legal advice). Losses can offset other business income.
Social contributions (ZUS) and healthcare contributions apply to business income.

Ministry of Finance (MF) Detailed Guidelines

The MF has issued multiple interpretative rulings and general guidance on crypto taxation. Key positions:
Crypto is treated as property (prawo majątkowe), not currency or financial instrument for income tax purposes (though it was previously treated as a property right under the Civil Code).
Acquisition cost includes the PLN value at the time of purchase. If bought with another crypto, the FMV in PLN at the time of trade is both the sale proceeds of the disposed asset and the acquisition cost of the acquired asset.
Airdrops and forks: Generally, the market value at receipt is taxable income. Hard forks creating new tokens are taxable at the time of receipt if the tokens have determinable value.
Lending and staking: Income from lending crypto or staking is considered revenue and may be taxed as other income or business income, depending on the taxpayer's profile.

Mining — Business Income

Cryptocurrency mining (kopanie) is consistently treated by Polish tax authorities as business income, even if conducted on a small scale.
Miners should register a business (CEIDG) and pay tax on the market value of mined coins at the time of receipt (mining reward).
Costs of mining (hardware, electricity, cooling, mining pool fees) are deductible business expenses.
When mined coins are subsequently sold, the sale proceeds are revenue and the previously taxed value is the cost basis — only the additional gain (if any) is taxable.

Crypto-to-Crypto Taxable Events

Every exchange of one cryptocurrency for another is a taxable event. For example, trading BTC for ETH triggers a disposal of BTC at its PLN FMV at the time of trade.
Using crypto to purchase goods or services is also a taxable disposal — the PLN value of the goods at the time of purchase is the sale proceeds.
Gifting crypto: Gifts to individuals outside the immediate family may trigger gift tax (inheritance and gift tax scale, 3-20%). Gifts to spouses or direct descendants are generally exempt up to high thresholds.
Non-taxable events: Transferring crypto between your own wallets, holding (HODLing), purchasing with fiat (no gain until disposal).

Record-Keeping and Reporting

Taxpayers must maintain detailed records of every crypto transaction: date, time, type, quantity, counterparty, PLN value at transaction time, fees.
Use exchange statements, blockchain explorers, and portfolio trackers to reconstruct your transaction history.
For each transaction, the PLN exchange rate can be determined from the exchange rate used by the crypto exchange, or the NBP (National Bank of Poland) mid-rate for that day.
Returns are filed electronically via e-Deklaracja or the e-Urząd Skarbowy portal. The deadline is April 30 of the following year.
