Bulgaria's parliament has approved a set of amendments that expand tax authorities' access to cryptocurrency user and transaction data, bringing the country's reporting framework into line with European Union standards.

The legislation, adopted on September 9, grants the National Revenue Agency broader access to information collected by crypto-asset service providers. The amendments implement EU rules designed to improve tax transparency and strengthen cooperation between national tax authorities, aligning Bulgaria with the DAC8 framework, which began applying across the EU on January 1, 2026.

DAC8, the EU's eighth amendment to its Directive on Administrative Cooperation in tax matters, extends the bloc's automatic information-exchange system between national tax authorities to crypto-assets, in line with the OECD's Crypto-Asset Reporting Framework.

Under the new requirements, crypto-asset companies registered and licensed in Bulgaria must provide user identification information to the National Revenue Agency. The required data includes users' names and addresses, dates and places of birth, tax residence jurisdictions, tax identification numbers, the types of-assets involved in transactions, and information on transfers and exchanges.

The rules also support the exchange of relevant information between Bulgaria, other EU member states and participating partner jurisdictions. Under DAC8, reporting crypto-asset service providers must collect information on reportable transactions involving EU-resident users. Authorities will use the data for automatic exchanges aimed at improving tax compliance and addressing tax evasion.

Because that exchange is automatic, information reported by a platform in one jurisdiction can be transmitted to the tax authority where a user is resident for tax purposes, extending cross-border visibility over crypto activity for national tax administrations.

Additional Compliance Layer for Crypto Platforms

The Bulgarian legislation arrives as the country's crypto industry undergoes wider regulatory changes under the EU's Markets in Crypto-Assets framework. Bulgaria's financial regulator has already moved toward licensing crypto-asset service providers under the MiCA regime.

Taken together, the two regimes place Bulgarian platforms under both of the EU's main crypto frameworks: MiCA, which sets how providers are authorized and operate, and DAC8, which determines what customer and transaction data they must report to tax authorities.

The new tax reporting rules add another layer of compliance for exchanges and other service providers. Platforms must now prepare systems capable of identifying customers, tracking reportable transactions and transmitting the required information to tax authorities.

For crypto users, the changes do not create a new tax. Instead, they give authorities greater visibility into transactions that may already have tax implications under existing rules.

The first EU-wide reporting cycle under DAC8 covers transactions from 2026, with information exchanges for that year expected by September 30, 2027, the point at which the new reporting chain first becomes operational across participating jurisdictions.
