Bulgaria Enacts Law Forcing Crypto Firms to Report User Transactions

New rules tighten tax oversight of digital assets and target withdrawals to self-custody wallets.

Bulgaria has adopted new legislation compelling cryptocurrency businesses operating in the country to report user transaction data to state authorities. The measure marks a significant expansion of financial oversight for digital asset activity within the Balkan nation.

According to crypto.news, the law requires crypto firms to disclose details of customer transactions as part of broader reporting obligations. AMBCrypto reported that the legislation also tightens tax rules applying to crypto holders, with particular focus on withdrawals made to self-custody wallets.

Self-custody withdrawals move funds out of exchange-controlled accounts and into wallets where users alone hold the private keys. Regulators across many jurisdictions have viewed this shift as a potential blind spot for tax enforcement. Once assets leave a regulated platform, tracking subsequent transactions becomes harder for authorities relying on exchange-level reporting.

Bulgaria's move fits into a wider pattern across the European Union. Member states have been working to align national rules with EU-level efforts to bring tax transparency to crypto asset service providers. Those efforts have pushed exchanges and custodians toward standardized reporting of customer holdings and transfers to tax authorities across the bloc.

The practical effect for crypto firms operating in Bulgaria is a new compliance burden. Companies will likely need to build or expand systems that capture transaction records and transmit them to regulators in a format authorities can use for tax assessment. For users, the law signals closer scrutiny of activity that moves funds beyond exchange oversight, including transfers to hardware wallets or other self-custody solutions.

Neither report specified an exact effective date or the precise transaction thresholds that would trigger reporting obligations. It also remains unclear how the law defines a qualifying crypto firm, or whether foreign platforms serving Bulgarian residents fall under its scope. These details typically emerge through subsequent regulatory guidance or amendments once a law of this kind takes effect.

The legislation nonetheless represents a clear policy direction. Bulgarian authorities are signaling that crypto transactions, including those ending in self-custody, will face greater tax and reporting scrutiny going forward.

Market Impact

For crypto exchanges and service providers operating in Bulgaria, the law introduces new compliance costs tied to transaction reporting infrastructure. Firms serving Bulgarian customers may need to reassess onboarding, recordkeeping, and data-sharing processes to meet the new obligations.

The emphasis on self-custody withdrawals could also influence user behavior, as some holders weigh the tax and reporting implications of moving assets off exchanges. Broader market effects will likely depend on how strictly the law is enforced and how it interacts with wider EU tax transparency initiatives already reshaping compliance expectations for crypto businesses across the bloc.

Bulgaria's new reporting law adds to a growing list of European jurisdictions tightening tax oversight of crypto transactions, with further details on enforcement and scope expected as implementation proceeds.
