1. Scope of This Article
The modern Web3 economy has generated crypto income streams that did not exist when Bulgaria's tax rules were drafted. This article addresses only the yield mechanisms where the law gives no direct answer:
- Staking — Proof-of-Stake validation, liquid staking (Lido, Rocket Pool)
- DeFi lending — Aave, Compound, Morpho
- DeFi yield farming — liquidity pools, AMMs (Uniswap, Curve), governance tokens
- NFTs — minting, buying, reselling, royalties
- Airdrops and retroactive protocol rewards
What this article does NOT cover:
- Ordinary buy/sell of cryptocurrencies — see Bulgarian Crypto Tax 2026
- Licensing of crypto asset service providers (CASP) and MiCA obligations — see MiCA and Crypto Licensing
- Corporate taxation of legal entities with crypto activity (10% CIT)
The target audience are Bulgarian tax residents under Art. 4 PITA who participate in DeFi and NFTs as investors (not professional traders).
2. The Problem: No Explicit Statutory Framework
Neither the Personal Income Tax Act (PITA) nor the Corporate Income Tax Act (CITA) defines “crypto asset”, “staking”, “DeFi”, or “NFT”. There is no dedicated chapter and no dedicated rate. Guidance from the National Revenue Agency (NRA) is limited but gradually emerging through rulings by the Director of the Tax & Social Insurance Methodology Directorate.
Absent explicit rules, tax treatment is derived by analogy with regulated categories of income:
| Analogy | Legal basis | Applies to |
|---|---|---|
| Financial assets | Art. 33(3) PITA | Cryptocurrencies, investment NFTs |
| Interest income | Art. 38 PITA | DeFi lending |
| Other income | Art. 35 PITA | Staking, airdrops, play-to-earn |
| Royalties | Art. 29(2) PITA | Art NFTs from the creator |
Guiding principle: If a crypto activity generates economic benefit (you receive value expressible in EUR), it is taxable. The absence of a “payer” or lack of fiat realization does not suspend the taxable event. A conservative reading is defensible on audit; an aggressive one may trigger reassessments with interest and penalties.
3. Staking — Tax Treatment
Staking is the locking of crypto assets in a Proof-of-Stake (PoS) blockchain network. In exchange, the validator (or delegator) receives rewards for participating in block validation. Typical networks: Ethereum, Cardano, Solana, Polkadot, Cosmos.
Classifying the Reward
Three possible classifications tested:
- Interest (Art. 38 PITA) — rejected: no legal payer, no loan, no fixed rate. The reward is algorithmic.
- Service fee — rejected: no employment or civil contract.
- Other income (Art. 35 PITA) — the most defensible classification: income from “other sources” not falling within other categories.
Taxable Event and Rate
Two-step taxation:
- On receipt of the reward: taxable income = market value of the token in EUR on the reward date. Rate: 10% under Art. 35 PITA.
- On subsequent sale: capital gain = sale price − market value on receipt. Rate: 10% with 10% statutory cost allowance → 9% effective.
Numerical Example
You delegate 32 ETH to a staking protocol. You receive 1 ETH reward when the market value is EUR 3,000.
- Tax on receipt: 10% × EUR 3,000 = EUR 300
- Six months later you sell the 1 ETH for EUR 3,500
- Capital gain: EUR 3,500 − EUR 3,000 = EUR 500
- Tax on sale: 9% × EUR 500 = EUR 45
- Total tax: EUR 345 on nominal value EUR 3,500
Liquid Staking (Lido, Rocket Pool)
In liquid staking you receive a “wrapped” token (stETH, rETH) representing the same economic exposure. Our analysis:
- Swap ETH → stETH: not a taxable event (ownership preserved via equivalent asset).
- Growth of the stETH balance (rebase) reflects accrued rewards: treated as Art. 35 income on accrual.
- Swap stETH → ETH: not a taxable event (reverse conversion).
- Sale of stETH for USDC/EUR: taxable event — 9% effective on the gain.
Practical tip: Document the market value of every reward on the date of receipt (screenshot from CoinGecko/CoinMarketCap). On audit the burden of proof is on you.
4. DeFi Lending (Aave, Compound)
DeFi lending is the supply of crypto assets as loans through smart contracts — you exchange liquidity for interest. No centralized institution exists; the protocol balances supply and demand algorithmically.
Legal Classification
The economic construct most closely resembles a consumer loan under Art. 240 of the Bulgarian Obligations and Contracts Act — delivery of fungible goods against a promise of equivalent return. The generated interest falls under Art. 38 PITA — 10% final withholding on the gross amount.
Taxable Event
- Deposit in protocol (supply): not a taxable event (ownership preserved).
- Interest accrual (aToken/cToken rebase): income on accrual, at EUR market value.
- Withdrawal from protocol: not a taxable event.
Rate: 10% final tax under Art. 38 PITA. Reporting: Schedule 8 of the annual tax return, code 01 (interest).
DeFi Loan Reporting — Schedule 11
Under Art. 50(1)(5) PITA, Bulgarian tax residents must report outstanding loans:
- Received crypto loans >EUR 5,113 (BGN 10,000) per year — reportable
- Provided loans >EUR 5,113 — same obligation
- Six-year cumulative threshold: EUR 20,452 (BGN 40,000)
- Values are determined in EUR on the loan date
Detailed in Reporting Outstanding Loans in the Annual Return (Schedule 11).
5. DeFi Yield Farming and Liquidity Pools
Yield farming is the most complex case from a tax perspective. You deposit two tokens in an automated market maker (AMM) such as Uniswap or Curve, receive an LP (liquidity provider) token representing your share of the pool, and in exchange collect:
- Trading fees from pool swaps
- Governance tokens as incentives (UNI, CRV, BAL)
- Additional rewards when “staking” the LP token
The Core Question: Is the Deposit a Swap?
Two competing readings:
- Conservative (recommended): Deposit = swap of two tokens for one LP token. Taxable event under Art. 33(3) PITA on deposit and on withdrawal.
- Aggressive: Deposit = retention of ownership through a representative asset. No taxable event until final realization to EUR/USDC.
The NRA has not taken an official position. On audit the conservative approach is more defensible.
Four Tax Moments in Yield Farming
- Pool deposit: realization — capital gain if the value of incoming tokens exceeds their acquisition cost.
- Trading fees: income under Art. 35 PITA (10%) on accrual.
- Governance tokens: income on receipt at market value (Art. 35).
- Withdrawal (remove liquidity): new realization — difference between the value of withdrawn tokens and the book value of the LP position.
Impermanent Loss
Impermanent loss is the difference between the value of tokens in the pool and their value if held outside. It is recognized as a capital loss on withdrawal and can offset gains from other crypto trades, but only within the same calendar year (Art. 33(6) PITA). Losses cannot be carried forward.
Recommendation from our practice: Before entering yield farming with a position above EUR 10,000, consult a tax advisor. Logging transactions in Excel/Koinly is mandatory — post-factum reconstruction is practically impossible.
6. NFTs — Tax Treatment
An NFT (Non-Fungible Token) is a unique digital asset on a blockchain. Unlike cryptocurrencies, NFTs are not fungible and can represent heterogeneous content: art, collectibles, gaming items, music, digital identifiers, or even tokenized real estate.
Classification — Depends on the Character
| NFT type | Classification | Rate |
|---|---|---|
| Investment (PFP collection, gaming) | Financial asset — Art. 33 PITA | 9% effective |
| Digital art (from creator) | Royalty — Art. 29(2) PITA | 6% effective (40% statutory cost) |
| Collectible (music, meme) | Financial asset (conservative) | 9% effective |
| Utility (service access) | Prepaid service (case-by-case) | Depends on analysis |
Minting an NFT
- Gas fees on mint: no taxable event, but added to the tax base (cost).
- First sale by the creator: income = sale price in EUR.
- If the NFT is a creative work (Art. 3 of the Copyright and Neighboring Rights Act) — royalty regime applies: 40% statutory cost, 6% effective rate.
- If it is collectible/gaming — financial asset: 9% effective.
Reselling an NFT
- Capital gain = sale price − acquisition cost (including gas fees at purchase).
- Tax: 10% with 10% statutory cost allowance → 9% effective.
- Royalties to the creator (typically 5–10%): deductible expense when computing the gain.
- Reporting: Schedule 5, Table 2.
NFT Games (Play-to-Earn)
In play-to-earn (Axie Infinity, Gods Unchained, etc.), the tokens and items received are treated as Art. 35 PITA income when converted into a liquid asset. In-game assets without a liquid market do not trigger taxable events until they are “moved out”.
7. Airdrops and Protocol Rewards
An airdrop is a free distribution of tokens from a protocol (often for prior usage). Examples: Uniswap UNI, Arbitrum ARB, EigenLayer EIGEN.
Tax Treatment
- On receipt: income under Art. 35 PITA at EUR market value on the claim date.
- If the token has no active market (not listed on any exchange, no transfers), market value is 0 — no tax on receipt.
- On subsequent sale: capital gain on the difference between sale price and value on receipt (9% effective).
Retroactive Airdrops and Pre-Listing Tokens
For retroactive distributions (LayerZero, Jito) the approach is the same: Art. 35 income on claim. If a token has no active market on receipt, market value is 0 — taxation arises on sale (the entire sale price is capital gain, as acquisition cost is EUR 0).
8. Special Cases — Fiat ↔ Crypto, Stablecoins
Core Scenarios
| Transaction | Taxable event? | Rate |
|---|---|---|
| Buy crypto with EUR/BGN | No — forms acquisition cost | — |
| Sell crypto for EUR | Yes — realization | 9% effective |
| Crypto → crypto (BTC → ETH) | Yes — dual realization | 9% effective |
| Crypto → USDT (stablecoin) | Yes — realization | 9% effective |
| USDT → USDC | Yes (technically) — minor gain | 9% effective |
Stablecoins Are Not the Same as EUR
USDT, USDC and DAI are not pegged to EUR. They track USD. A swap EUR → USDT and back generates a small FX gain or loss, which is formally a taxable event. In practice the NRA rarely audits such differences, but the analysis is the same.
Bridges
Transferring a token between chains (ETH mainnet → Arbitrum) is not a swap — ownership of the same asset is preserved. Gas fees are treated as a cost that reduces the future capital gain.
9. MiCA from 01.07.2026 and DAC8 from 01.01.2027
Regulation (EU) 2023/1114 (MiCA) introduces a common European regime for crypto services. The transition period for Bulgarian CASPs ends on 01.07.2026.
Who MiCA Applies To
- In scope: centralized exchanges, custodial wallet providers, staking platforms marketing to EU clients, CASPs (Crypto-Asset Service Providers).
- Out of scope: fully decentralized DeFi protocols with no operator (Uniswap v3, Aave), individual investors.
- Excluded: NFTs (Art. 2(2) MiCA) where not fractional/fungible.
Tax Consequences of MiCA
MiCA does not change the tax rate — it remains 10% / 9% effective. But MiCA creates the infrastructure for reporting:
- MiCA-licensed platforms will identify clients (KYC).
- From 01.01.2027 — DAC8 (Directive 2023/2226) obliges platforms to report transactions of Bulgarian tax residents to the NRA.
- Reporting deadline: by 31 January of the following year.
- The NRA will receive automatic information on crypto transactions of Bulgarian clients.
What This Means for Investors
Until 01.01.2027 the NRA relies primarily on bank transfers to/from exchanges and voluntary declarations. After 01.01.2027 transparency changes dramatically — inaccurate reporting will be easily detected through automatic information exchange.

Closing Remarks
Until the NRA issues official guidance, a conservative reading by analogy remains most defensible: staking — 10% on receipt; DeFi interest — 10% final; NFTs — 9% effective. With MiCA (01.07.2026) and DAC8 (01.01.2027) in force, the era of “invisible” crypto income is ending.
