Buying an Apartment with Bitcoin in Bulgaria: Is It Possible and How Does It Work?

In recent years, the question of whether you can buy an apartment with Bitcoin has started appearing more frequently in Bulgaria. It is not yet common practice, but it is no longer exotic. The short answer is: yes, such a transaction is possible. But it does not happen automatically, not every notary will be equally comfortable with it, and there are several points where people typically underestimate the risk.

Is It Legally Possible Under Bulgarian Law?

Yes. Bulgarian civil law allows the parties to freely determine the content of a contract, provided the agreement does not violate the law or public morals. Property transfers have a strict requirement: they must be completed in notarial form. Bitcoin is not an official currency in Bulgaria - this became even clearer after Bulgaria adopted the euro on 1 January 2026 - but it can be used as consideration in a transaction if both parties agree.

How It Works in Practice

There are typically two approaches. The first is to structure the deal as an exchange - the notarial deed describes one party transferring the apartment and the other transferring a specified amount of Bitcoin. The second is a formal sale of the apartment where payment is agreed in crypto. The right approach depends not just on legal theory, but on how the specific notary wants to see the documentation.

Taxes: Where People Most Often Go Wrong

If you give Bitcoin and receive an apartment, this is not a tax-free swap just because no euros passed through a bank account. Under Bulgarian income tax law, income from the sale or exchange of financial assets - including virtual currencies - is taxable. The law allows a 10% deduction for costs. If you acquired Bitcoin at a lower price and are now spending it at a higher value, a taxable gain may arise. A Bitcoin-for-apartment exchange often creates two separate tax events: one on the property, one on the crypto asset.

AML Checks Are the Real Filter

Notaries, lawyers, and other participants in such a transaction cannot simply accept that the crypto is mine and move on. The European AML framework is considerably stricter for crypto assets. Rules on information accompanying transfers of crypto assets have been in force in the EU since 30 December 2024. In practice: if you want to pay with Bitcoin, you must be prepared to show where it came from - exchange history, KYC documents, transaction traceability. Without this clarity, notaries will often simply decline to take on the transaction.

The Valuation Problem

There is also a practical question: at what value is Bitcoin counted on the day of the transaction? If the rate moves sharply, a dispute over exactly how much BTC is owed can arise easily. A well-prepared transaction fixes either a specific euro value for the property, or a specific mechanism for determining BTC at a precise moment from a specific market source.

Is It Worth Doing at All?

Yes - there are cases where it makes complete sense. If both parties understand what they are doing, the origin of the crypto is clean, and the tax side has been worked out in advance, the transaction can proceed. But if the goal is simply to do it faster and without too many questions, this type of deal is usually not the right choice. In many situations, the more practical route is to sell the crypto first through a traceable channel, then buy the property through the standard procedure.

Conclusion

Buying an apartment with Bitcoin in Bulgaria is possible. It is not a legal fantasy and it is not prohibited simply because the consideration is in crypto. But it should not be treated like an ordinary purchase. There is notarial complexity, tax exposure, AML scrutiny, and technical questions that must be resolved in advance. Work through the structure, tax implications, and origin documentation first - and only then approach a crypto lawyer and notary together.
