Bulgaria gives tax officials crypto data access

• Bulgaria’s National Assembly has approved rules giving tax authorities access to detailed crypto user data.
• The 149–0 vote requires crypto firms to register users and report transaction-level information.
• The changes implement EU tax transparency rules and enable wider cross-border data sharing.

Bulgaria’s National Assembly has approved amendments giving the National Revenue Agency access to detailed data on crypto-asset users as the country strengthens tax reporting rules.

Lawmakers voted 149–0 on September 9, with 10 abstentions, to amend the Tax and Social Security Procedure Code and implement two European Union directives.

The changes require companies dealing in crypto assets to register users and report names, addresses, birth details, tax residency information and tax identification numbers to the National Revenue Agency.

Providers must also submit transaction-level data covering the total gross amount received, units traded, fiat purchases and sales, and crypto-to-crypto transactions for each asset type.

The measures are designed to close reporting gaps and strengthen efforts to prevent tax avoidance through greater information sharing between EU member states and partner jurisdictions.

The new requirements could increase compliance costs for smaller crypto businesses, with some traders and firms warning that additional reporting could weaken Bulgaria’s fintech competitiveness.

The legislation follows an EU requirement for member states to adopt the relevant directives by December 31, 2025, while privacy advocates have raised concerns about the scope and security implications of the data collection.
