Bulgaria is tightening its crypto tax rules with new measures that explicitly target self‑custody withdrawals, marking one of the European Union’s most assertive moves to close reporting gaps and strengthen enforcement under the DAC8 framework.
The National Revenue Agency (NRA) is preparing to treat wallet‑to‑wallet transfers as potential taxable events unless users can prove ownership continuity, with stricter documentation requirements and heightened scrutiny of on‑chain activity.
Stricter Controls for Strengthened Traceability
Bulgaria’s tax authority is preparing to classify self‑custody withdrawals—transfers from centralized exchanges to private wallets—as reportable events when users cannot demonstrate that the destination wallet belongs to them.
The NRA’s position is shaped by the EU’s DAC8 reporting rules, which require crypto‑asset service providers to collect tax‑residency information and submit standardized annual transaction data for all reportable users.
The tightening of rules does not introduce a new tax category. Bulgaria already taxes crypto gains at a flat 10% rate, with an effective rate of approximately 9% after automatic deductions.
What is changing is the information flow: the NRA will now receive more granular data from exchanges, and self‑custody transfers will no longer be treated as invisible movements.
The new approach is intended to close gaps where users previously moved assets off exchanges to avoid traceability. Under DAC8, centralized exchanges must report identity‑linked activity, but self‑custody wallets remain pseudonymous.
Bulgaria’s updated rules aim to bridge this gap by requiring taxpayers to prove continuity of ownership when moving assets to private wallets. If they cannot, the transfer may be treated as a disposal—triggering capital gains tax.
Why Bulgaria is Acting Now
Bulgaria’s tightening of crypto tax rules is part of a bigger EU‑wide effort to standardize reporting and reduce tax evasion. DAC8, which took effect in 2026, mandates automatic exchange of crypto transaction data across EU tax authorities.
Bulgaria’s Parliament adopted the first reading of its DAC8 implementation bill on 27 August 2026, signaling the country’s intent to enforce the framework aggressively.
The NRA has long emphasized that crypto gains were always taxable, but enforcement was limited by the lack of standardized reporting. With DAC8, exchanges operating in the EU must provide identity‑verified transaction data, making it easier for authorities to match activity to taxpayers. Self‑custody transfers, however, remain a blind spot—one Bulgaria now aims to address.
The move also reflects Bulgaria’s experience with high‑volume traders and the rise of platforms like Hyperliquid, where activity is fully on‑chain but not tied to KYC identities.
While such platforms do not provide direct reporting, the transparency of blockchain activity means that once a wallet is linked to a person, the entire transaction history becomes visible. Bulgaria’s updated rules leverage this dynamic to strengthen enforcement.
Bulgaria’s Next Move
As Bulgaria moves toward full DAC8 implementation, taxpayers should expect increased communication from the NRA regarding documentation requirements for self‑custody transfers.
Guidance may include acceptable forms of proof, such as signed messages from wallets, transaction logs, or linkage through hardware wallet serials.
The Parliament’s DAC8 bill is still pending final approval, but its first‑reading passage indicates strong political support. Once enacted, Bulgaria will likely issue secondary regulations clarifying how self‑custody withdrawals will be evaluated, what constitutes sufficient proof of ownership, and how disputes will be resolved.
Crypto service providers operating in Bulgaria will also face new obligations.
Under MiCA, providers must obtain licenses from the Financial Supervision Commission by 1 July 2026, and DAC8 requires them to collect tax‑residency information and report annual transaction data.
To active traders, the NRA’s stance on self‑custody may influence how they structure their activity. Heavy trading could trigger reclassification as a commercial enterprise under Article 26(7) of the Personal Income Tax Act, subjecting them to a 15% business tax regime rather than the standard 10% personal rate.
Bulgaria’s updated rules may accelerate such reclassifications by providing clearer evidence trails. Furthermore, Bulgaria’s approach may influence other EU jurisdictions. DAC8 provides a baseline for reporting, but member states retain discretion in enforcement.
If Bulgaria’s model proves effective, other countries may adopt similar scrutiny of self‑custody withdrawals, reshaping how European taxpayers manage their digital assets.
