Jetzt berechnen →In Belgium, most cryptocurrency gains are classified as "diverse income" (inkomsten uit diverse bron) and taxed at a flat rate of 30%.
This is defined by Belgian tax law (Article 90 bis Wetboek Inkomstenbelastingen 1992).
Example: You buy 1 BTC at €40,000, sell it at €70,000. Gain: €30,000. Tax due: €30,000 × 30% = €9,000.
What Gets Taxed?
- Trading gains: Buying and selling crypto. Taxed as diverse income at 30%.
- Staking rewards: Income from staking. Taxed as diverse income at 30% (or as professional income if you're classified as professional).
- Yield farming: defi-steuern-2026">DeFi returns. Taxed as diverse income at 30%.
- Mining/Airdrops: New crypto received. Taxed at market value on receipt date.
- Crypto-to-Crypto swaps: Even BTC → ETH swaps are taxable events in Belgium!
Two Classifications: Investor vs Professional
Belgium distinguishes between two types of traders:
- Investor (30% diverse income): Occasional trading, no business registration.
- Professional trader (Progressive income tax + social contributions): Regular trading, professional registration required.
Tax Declaration: Inkomstenbelastingaangifte 2026
You must declare all cryptocurrency gains in your annual tax return:
- Submit by May 31 deadline
- Report all gains and losses
- Specify acquisition and sale prices
- Calculate net gain or loss
Loss Offsetting
If you have losses, you can offset them against gains in the same year.
Example:
- Gain from ETH: +€5,000
- Loss from BTC: -€2,000
- Net gain: €3,000 × 30% = €900 tax
CARF 2026: Automatic Reporting Starts
From 2026, CARF (Common Reporting Standard) kicks in. Exchanges (Binance, Coinbase, Kraken) will automatically report your trading data to Belgian tax authorities.
The Belgian government will know every transaction.
Professional Trader Classification
If you trade frequently and register as professional, your taxes change significantly:
- Progressive income tax (13-50%, depending on income bracket)
- Social security contributions (~20% on self-employed income)
- More deductions allowed, but higher total tax burden
Strategies for 2026
Golden rule: Declare everything. CARF will know. Belgium's 30% is already reasonable – don't risk penalties.
If you're unsure whether you're "professional" or "investor," consult a Belgian tax advisor.
Real Example: How Belgian Crypto Taxes Work
Let's walk through a realistic Belgian investor scenario for 2026:
Investor: Jan (30-year-old, employee)
- Buys 2 BTC in March 2024 for €50,000 each (€100,000 total)
- Receives €5,000 in staking rewards during the year
- Sells 1 BTC in October 2024 for €70,000
- Loses €3,000 on an altcoin position
Tax Calculation:
- BTC gain: €70,000 – €50,000 = €20,000
- Staking income: €5,000
- Altcoin loss: -€3,000
- Net taxable income: €20,000 + €5,000 – €3,000 = €22,000
- Tax due: €22,000 × 30% = €6,600
Jan needs to declare this in his annual tax return by May 31, 2026. CARF reporting starts, so the government already knows about his exchange activity.
Common Mistakes Belgian Crypto Investors Make
- Not reporting small wins: "It's only €500, they won't notice." CARF will report it. Penalties are steep.
- Crypto-to-crypto swaps (BTC → ETH): Many think this isn't taxable because no EUR involved. Wrong. It's a sale event in Belgium.
- Not tracking purchase prices: You need to prove your cost basis. Without records, Belgian tax authorities can estimate high.
- Mixing private wallet and exchange accounts: Both are reportable. Transfers between them don't "reset" your holding period.
- Ignoring professional classification: If you trade frequently, the tax office might reclassify you as professional retroactively – and hit you with back taxes + penalties.
CARF 2026: What Changes for You?
CARF is the "Common Reporting Standard" – a global automatic exchange of financial information between countries.
What happens in 2026:
- Binance, Coinbase, Kraken, and other major exchanges report all Belgian user accounts to Belgian tax authorities
- They report: account holder, transactions, balances, proceeds from sales
- The Belgian government has a complete picture of your crypto activity
- Non-declaration becomes tax evasion with serious penalties (minimum €100 per transaction)
Silver lining: You can't get away with hidden gains, but compliance is now crystal clear – no ambiguity about what counts.

| Losses | Can offset within same year | Can offset + carry forward |
FAQ: Belgian Crypto Taxes 2026
If I hold crypto for 1+ year, is it tax-free in Belgium?
No. Unlike Germany, Belgium has no holding period exemption. Even a 5-year hold gets taxed at 30% on sale. The only exception: if you're classified as an investor and never sell – then it's not realized income.
What if I live in Belgium but trade on a US exchange?
Still taxed in Belgium. Your residency is what matters. You must file in Belgium and declare all worldwide crypto income. Double taxation is possible if you also file in the US – consult a cross-border tax pro.
Can I deduct trading losses against my salary?
As an investor, no – losses stay within "diverse income." As a professional, yes – business losses can offset other income, but this triggers higher tax rates overall. Consult an advisor.
