Bulgaria’s parliament has given final approval to amendments requiring crypto asset service providers to report detailed customer and transaction data to the National Revenue Agency, aligning national law with the European Union’s DAC8 tax transparency framework.
The National Assembly passed the changes to the Tax and Social Security Procedure Code on Sept. 9 with 149 votes in favor, none against and 10 abstentions in the 240-seat chamber. The legislation transposes two European directives and comes more than eight months after the EU deadline for member states to complete national transposition, which was Dec. 31, 2025.
Under the rules, reporting providers must register and submit customer identities—including name, address, date and place of birth, tax identification number and jurisdiction of tax residence—as well as transaction records covering purchases, sales, transfers, exchanges and transactions involving fiat currencies or other crypto assets. Reports must include total gross amounts, the number of units traded and the number of purchases or sales made against fiat currencies. Crypto-to-crypto transactions are also covered.
The measures implement the EU’s Directive on Administrative Cooperation, known as DAC8, which requires crypto service providers to collect information for exchange between national tax authorities. Withdrawals to external addresses, including self-custody wallets, may be included, although providers are not required to continuously report transactions conducted entirely within self-custody.
Reporting providers began collecting data from Jan. 1, 2026, with the first full-year reports due in 2027. EU authorities are expected to exchange 2026 data by Sept. 30, 2027. Existing individual customers generally have until Jan. 1, 2027, to provide valid tax-residency self-certification; those who fail after two reminders and a 60-day period may face restrictions.
The European system operates alongside the OECD’s Crypto-Asset Reporting Framework, which began data collection in 48 jurisdictions at the start of 2026. The UK and India have also introduced related reporting changes, reflecting a broader international push to capture crypto activity for tax authorities.
