Purchasing and Selling Real Estate in Bulgaria Using Cryptocurrency

Private Clients Insights, Blockchain & Cryptocurrency, Real Estate

In recent years, Bulgaria has seen increasing interest in real estate transactions using cryptocurrency as full or partial consideration. This reflects global trends in digital asset adoption but engages a complex intersection of property law, financial regulation, anti-money-laundering (AML) compliance, and taxation. Although possible, such transactions require adherence to strict legal and regulatory standards. They are of growing importance to investors, developers, financial institutions, and Crypto-Asset Service Providers (CASPs) active in Bulgaria’s real estate market.

Legal Framework in Bulgaria and the EU

Property Transfer Formalities

Under Bulgarian law, ownership of immovable property transfers only through a notary deed executed before a Bulgarian notary, pursuant to the Property Act, the Obligations and Contracts Act, and the Notaries and Notarial Activities Act. Private contracts cannot transfer ownership they serve only to record commercial terms.

While consideration may be paid in cryptocurrency, the purchase price in the notary deed must always be expressed in legal tender. As of 1 January 2026, Bulgaria adopts the euro (EUR) at a fixed rate of 1 EUR = 1.95583 BGN, with dual circulation throughout January 2026.

Classification of Cryptocurrency

In Bulgaria, cryptocurrency is recognised as an asset that can be held, transferred, and exchanged, but not as legal tender. The National Revenue Agency classifies it as a financial asset for tax purposes, meaning it cannot substitute mandatory statutory formalities.

At the EU level, the Markets in Crypto-Assets Regulation (MiCA) (Regulation (EU) 2023/1114) became fully applicable on 30 December 2024. Bulgaria implemented it through the Markets in Crypto-Assets Act (effective 8 July 2025), which establishes licensing, governance, and AML obligations for CASPs under the supervision of the Financial Supervision Commission and, for e-money tokens, the Bulgarian National Bank.

These frameworks ensure transaction traceability, source-of-funds verification, and compliance for crypto-linked property transfers.

Transitional Provisions

CASPs registered under Bulgaria’s previous AML regime before 30 December 2024 may operate without a full MiCA licence until 1 July 2026. 

Structuring Crypto-Based Property Transactions

Contract of Exchange

The real estate is exchanged for a specified amount of cryptocurrency. Under Bulgarian law, since cryptocurrency is not recognised as an official legal tender, a property transfer against cryptocurrency constitutes, strictly speaking, a contract of exchange rather than a sale. One party transfers ownership of the immovable property, whilst the other transfers rights to an agreed quantity of cryptocurrency.

The notarial deed typically reflects the exchange mechanism, with the cryptocurrency valued in EUR for the purposes of calculating statutory fees. This approach is commonly regarded as an appropriate legal characterisation where cryptocurrency functions as the consideration, although practice may vary depending on jurisdiction and notarial interpretation.

Applicability of the Restrictions on Cash Payments Act

The Restrictions on Cash Payments Act (RCPA) prohibits cash payments of EUR 10,000 or more outside the banking system. However, because cryptocurrency transfers are not classed as “cash payments,” the RCPA does not apply to property-for-crypto exchanges. This makes exchange contracts a viable route for crypto transactions.

Preliminary Contracts and Deposits

It remains standard to conclude a preliminary contract before the final deed under Article 19 of the Obligations and Contracts Act. The buyer commits to pay, and the seller commits to transfer ownership, either may apply to court to perfect the transfer if the other breaches.

Deposits may be paid in cryptocurrency, provided key elements are addressed:

• Specified cryptocurrency, amount, and EUR valuation source.
• Clauses mitigating price volatility.
• AML-supporting documentation, including proof of source of funds and transaction history.

Clear valuation and conversion mechanisms help minimise disputes and ensure compliance.

Notarial Requirements

Notaries do not handle or execute on-chain transfers but must verify:

• Complete identification and beneficial ownership details.
• The type and valuation method of cryptocurrency used.
  • Proof of source of funds, AML declarations, and CASP-issued documentation verifying the transaction’s provenance.

Absence of compliant documentation may lead to notarial refusal.

Compliance and AML Obligations

Under the Prevention of Money Laundering Act, aligned with EU Directive (EU) 2015/849, notaries and CASPs are “obliged entities.” They must apply enhanced due diligence to high-value crypto transactions, including verifying the origin and traceability of assets. Transactions involving unregulated exchanges, mixers, or privacy tools face elevated scrutiny and reporting obligations to the Financial Intelligence Directorate.

Engaging a licensed CASP is strongly recommended. A MiCA-authorised intermediary can provide verified transaction records, custodial statements, KYC information, and official exchange rates. Notaries commonly rely on such evidence before executing deeds.

Taxation

When cryptocurrency is used in real estate transactions, both parties may incur taxable gains:

• Sellers pay 10% personal income tax on gains from appreciated cryptocurrency, with a 10% expense deduction.
• Corporate sellers include such income in their corporate tax base, also taxed at 10%.
• Buyers who dispose of appreciated cryptocurrency to acquire property likewise realise taxable capital gains.

The buyer also bears property transfer tax, notarial, and registration fees. Frequent crypto trading may trigger professional trader classification, depending on overall activity patterns.

Practical Risks and Limitations

Volatility and Pricing

Cryptocurrency’s price volatility represents the main commercial risk. Parties should:

• Fix valuation timestamps using reliable exchanges.
• Use narrow settlement windows to limit exposure.
• Provide EUR-based adjustments or supplementary cash deposits.

These mechanisms stabilise valuation during the period between preliminary contract and final deed.

Banking and Financing

Bulgarian banks neither accept crypto as collateral nor offer loans denominated in crypto. Buyers needing mortgage financing must convert crypto to EUR before settlement, which may itself create taxable gains.

Red Flags

Transactions may be refused by notaries or CASPs if they involve:

• Unregulated offshore intermediaries or privacy-enhancing tools;
• Inconsistent or unverifiable wallet, KYC, or fund-source records;
• Attempts to undervalue property to reduce taxes.

Such features can trigger mandatory AML reporting and halt completion.

Best Practices for Compliance

To ensure smooth execution, parties should:

• Use licensed CASPs providing verified records and AML documentation.
• Record the property price in EUR in the deed, even if cryptocurrency serves as economic consideration.
• Maintain comprehensive AML files: KYC data, UBO declarations, wallet histories, CASP confirmations.
• Engage tax and legal advisers early on to assess gain recognition and reporting obligations.
• Define volatility protections and valuation methods clearly in preliminary contracts.
• File the notary deed promptly for registration in the Property Register.

Conclusion

Crypto-linked real estate transactions in Bulgaria are legally achievable when structured and documented correctly. Ownership must always transfer via notary deed with the price stated in EUR, but cryptocurrency can validly function as economic consideration. With proper valuation, documentation, and compliance through MiCA-licensed CASPs, such deals can proceed smoothly. As Bulgaria integrates the euro and EU crypto regulations, disciplined structuring, full transparency, and early legal and tax planning remain essential to success in this evolving area.
