Bulgaria has amended its Tax and Social Security Procedure Code to bring in new reporting duties for crypto service providers, aligning its rules with the European Union’s latest tax transparency framework for digital assets.

The changes require providers to register with the National Revenue Agency and submit customer identification details together with data on crypto transactions and related fiat flows. The reporting period began on January 1, 2026, with the first annual filings due by June 30, 2027.

New reporting duties for crypto platforms

The amendments were passed by Bulgaria’s National Assembly last week and published in the official gazette on September 15, clearing the way for enforcement. The new provisions apply to entities that process cryptocurrency transactions for taxpayers in the country.

Under the revised rules, crypto service providers must give the National Revenue Agency detailed information on customer activity. That includes purchases, sales, transfers and exchanges of digital assets, broken down by category, as well as the number and total volume of transactions and associated fiat movements.

The identification data to be reported includes personal tax numbers, full names, dates of birth, permanent addresses and countries of tax residence. Reports will also cover transfers between accounts on crypto platforms and self-hosted wallets, but providers are not required to monitor movements between external private addresses.

Annual filing timetable starts with 2026 activity

The law sets a once-a-year electronic reporting cycle. Service providers must file the required data by June 30 of the year after the information was collected.

Because the first covered period started on January 1, 2026, the first submissions are scheduled for June 30, 2027. The framework is designed to give Bulgarian tax authorities access to standardized information about crypto activity in line with broader EU cooperation rules.

Separate licensing regime under MiCA

The reporting law sits alongside Europe’s wider crypto regulatory framework. From July 1, 2026, only licensed businesses are allowed to offer crypto services within the EU under the Markets in Crypto-Assets regulation, or MiCA.

Bulgaria had already adopted legislation to implement MiCA on June 20, 2025, and that law entered into force in early July of the same year. In Bulgaria, MiCA licenses are issued by the Financial Supervision Commission.

According to the report, the commission has granted only two licenses so far. At the same time, more than 70 firms have informed the regulator that they hold licenses issued in other EU member states, allowing them to operate across the bloc.

Part of the EU’s DAC8 transparency push

The newly adopted Bulgarian bill, numbered 52-602-01-10, transposes the latest changes to the EU’s Directive on Administrative Cooperation into national law. The DAC8 update extends that system to crypto assets, introducing automatic exchange of information in this area for the first time.

Lawmakers approved the bill on second and final reading on September 9, with 149 votes in favor, none against and 10 abstentions. Bulgaria had been late in making the change, as EU member states were supposed to implement the directive by the end of 2025.

The next confirmed step is the cross-border exchange of the reported data between EU tax administrations. Under the EU timetable, information covering 2026 transactions should be shared no later than September 2027, nine months after the end of the calendar year.
