Bulgaria passes law requiring crypto firms to report user transactions to tax authority

Bulgaria's National Assembly voted 149-0 on September 9, 2026, to pass tax code amendments requiring crypto service providers to report detailed customer identities and transaction data to the National Revenue Agency. The law transposes the EU's DAC8 directive, enabling cross-border tax information sharing to curb evasion. Crypto firms must collect names, tax IDs, and transaction details, including crypto-to-crypto trades, with the first annual reports due by June 30, 2027.
