[Polish Crypto Investors Who Fail to Report Gains May Face Punitive Tax Rates of Up to 75%] Earlier this month, Polish President Karol Nawrocki signed a new law incorporating the EU DAC8 directive into national legislation. Investors who fail to report cryptocurrency gains in accordance with regulations may face punitive tax rates of up to 75%. The DAC8 directive requires platforms such as exchanges, brokers, and wallet service providers to collect user and transaction data and report it to tax authorities, with tax departments across member states automatically sharing this information. Through this, the Polish National Revenue Administration (KAS) will gain insight into the holdings and transactions of domestic cryptocurrency investors. It is estimated that approximately 3 million people in Poland own cryptocurrencies, but only about 1% of investors comply with tax regulations. Under current rules, cryptocurrency trading gains from 2025 must be reported via the PIT-38 form by April 30, 2026, and are subject to a 19% capital gains tax rate. Mining and staking rewards are tax-exempt upon receipt but become taxable when converted into fiat currency.
