TechFlow News, March 18: According to Cryptopolitan, Polish President Karol Nawrocki signed a new law earlier this month formally incorporating the EU’s DAC8 Directive into national legislation. Investors who fail to declare cryptocurrency gains in compliance with the law will face a punitive tax rate of up to 75%.
DAC8—the Eighth Amendment to the EU Directive on Administrative Cooperation in the Field of Direct Taxation—specifically targets digital assets. It mandates exchanges, brokers, and wallet service providers to collect user and transaction data and report it to tax authorities. Tax administrations across EU member states will automatically share this information. Poland’s National Revenue Administration (KAS) will thus gain visibility into domestic cryptocurrency investors’ holdings and transactions.
Local media estimate that approximately 3 million people in Poland hold cryptocurrency, yet only about 1% currently comply with tax obligations. Under current rules, capital gains from cryptocurrency transactions realized in 2025 must be declared by April 30, 2026, using the PIT-38 tax return form, subject to a flat capital gains tax rate of 19%. Mining rewards and staking rewards are tax-exempt upon receipt but become taxable upon conversion into fiat currency.
