This is for Bulgarian tax-resident individuals holding or trading cryptoassets who need to understand how gains are taxed and recorded.
For a Bulgarian tax-resident individual investing privately, realised cryptocurrency gains are generally included in the annual tax base and taxed at 10%. The taxable result is based on realised transactions, not simply holding an asset. Frequent, organised activity can instead be treated as business activity, with different tax and social-security consequences.
Where we stand
Crypto tax is highly fact-specific — the investor/trader line, staking, mining, lending, derivatives and NFTs all change the answer. This guide sets out the private-investor baseline; take tailored advice for anything business-like or cross-border.
How is crypto taxed in Bulgaria?
For a Bulgarian tax-resident individual investing privately, realised cryptocurrency gains are generally included in the annual tax base and taxed at 10%. The taxable result is based on realised transactions, not simply holding an asset. Frequent, organised activity can instead be treated as business activity, with different tax and social-security consequences.
Investor or trader?
| Profile | Typical treatment | Tax point |
|---|---|---|
| Private investor | Income from sale or exchange of cryptoassets | 10% on the annual taxable result, subject to the statutory calculation rules. |
| Frequent trader acting as a business | Business income / sole-trader treatment may apply | 15% tax can apply, alongside possible social-security obligations. |
| Company trading crypto | Corporate income | 10% corporate tax on taxable company profit; accounting and VAT analysis required. |
| Mining, staking or similar rewards | Depends on facts and regularity | May be treated as income on receipt or business income; obtain tailored advice. |
What is a taxable crypto event?
| Transaction | Typical tax relevance |
|---|---|
| Selling crypto for EUR or another fiat currency | Normally realises a gain or loss. |
| Exchanging one cryptoasset for another | Can be a taxable disposal; do not assume crypto-to-crypto swaps are exempt. |
| Spending crypto on goods or services | Can be a taxable disposal. |
| Moving crypto between your own wallets | Normally not a disposal, but keep records. |
| Holding crypto without disposal | Usually no realised-gain tax merely from market movement. |
How is the private-investor gain calculated?
The starting point is the difference between documented sale proceeds and documented acquisition cost for relevant disposals. Annual gains and losses are aggregated under the statutory rules, and the positive annual result may benefit from the applicable 10% statutory expense deduction before being included in the annual tax base. Keep exchange exports, trade confirmations, wallet records, fees and EUR values on each transaction date.
A simple illustration
| Item | Amount |
|---|---|
| Proceeds from realised disposals | €20,000 |
| Documented acquisition cost and directly relevant costs | €12,000 |
| Pre-deduction result | €8,000 |
| Illustrative 10% statutory expense deduction | €800 |
| Taxable amount | €7,200 |
| Illustrative income tax at 10% | €720 |
This is simplified and is not a substitute for a transaction-by-transaction calculation. Treatment can differ for trading activity, company activity, airdrops, mining, staking, lending, derivatives, NFTs and cross-border facts.
When do you file and pay?
A Bulgarian tax-resident individual generally reports relevant crypto income in the annual personal income-tax return for the calendar year. For 2026 income, the normal filing deadline is 30 April 2027. Accurate classification and the correct annex/table are important, particularly where activity is business-like.
Reporting is becoming more visible
Bulgaria has adopted measures implementing expanded crypto-asset reporting and exchange of information. Licensed or registered crypto-asset service providers will be required to report customer identification, tax residence and transaction data, with initial reporting covering 2026 activity expected in 2027. The practical message is simple: retain records and report realised gains accurately.
Record-keeping checklist
- Exchange CSV exports and trade confirmations.
- Wallet addresses and transfer records.
- Acquisition dates, costs and transaction fees.
- EUR conversion methodology and values on transaction dates.
- Evidence of staking, lending, mining or airdrop receipts.
- A reconciliation between wallet balances, exchange data and annual return figures.
