Poland has officially incorporated the EU DAC8 directive into its national legislation, following a recent law signed by President Karol Nawrocki. The directive mandates that cryptocurrency exchanges, brokers, and wallet service providers collect and report user and transaction data to tax authorities. Investors failing to declare crypto gains as required will face a punitive tax rate of up to 75%. Under the current regulations, cryptocurrency trading income for 2025 must be declared by April 30, 2026, using the PIT-38 form, subject to a standard capital gains tax rate of 19%. Mining and staking rewards are tax-exempt upon receipt but become taxable when converted to fiat currency.
