Bulgaria Tightens Oversight of Crypto Transactions: Transparency or the End of Anonymity

Edited by: Yuliya Shumai

In September 2026, the Bulgarian parliament unanimously, with 149 votes against zero and ten abstentions, adopted amendments obliging crypto companies to transmit detailed data on clients and their transactions to the tax authorities. The law, more than eight months late after the European deadline, brings the country into the common DAC8 system and prompts reflection: is crypto truly still an instrument of financial freedom, or is it gradually turning into just another controlled asset?

The amendments to the Tax and Social Insurance Codes require crypto-asset service providers to collect and send to the National Revenue Agency the names, addresses, dates and places of birth, tax identification numbers and tax residency jurisdictions of users. In addition, companies must disclose asset types, total transaction amounts, the number of units, as well as fiat and crypto-to-crypto transactions. The data will be exchanged between EU tax services, which directly affects those who hold assets on Bulgarian or European platforms.

Behind this decision lies not only a desire to combat tax evasion but also the logic of institutional coordination. European authorities have long noted that the cross-border nature of crypto transactions complicates the tracking of taxable events. Bulgaria, like other countries, is now forced to integrate international standards, even if this means additional costs for local businesses and users.

For the ordinary investor, the changes mean the end of the illusion of complete anonymity when using centralized services. Those who prefer self-custodial wallets remain in relative shadow for now, but even here the DAC8 rules leave loopholes: withdrawals to external addresses may end up in reports. As a result, personal decisions about storing assets acquire a new tax and legal tint.

Let us compare the situation to the flow of water in a river: while the water flows freely along the riverbed, it is difficult to measure, but as soon as it passes through locks — dams, meters and reports — every litre becomes visible and accountable. So it is with crypto: decentralized by nature, it is increasingly forced to pass through the regulated "locks" of intermediaries, losing part of its original appeal.

Experts emphasize that the first full reports for the year 2026 are expected in 2027, and negligent clients risk restricted access to accounts after two reminders and a 60-day deadline. This creates a practical incentive for the timely provision of data on tax residency and for keeping one's own documentation.

In the long term, the law strengthens the trend toward global tax transparency, in which states are learning to exchange information faster than users can adapt. For those who build personal wealth with the help of digital assets, this is a signal to reconsider storage and reporting strategies in order to avoid unexpected claims.

In the end, crypto investors should remember: the freedom to own assets is now closely intertwined with the obligation to declare them.
