Crypto Tax Belgium 2026: Complete Guide (30% Diverse Income, Classification & CARF)

In Belgium, cryptocurrency gains are taxed at 30% as "diverse income" (inkomsten uit diverse bron). The classification depends on whether you're an investor or professional trader. Here's everything you need to know about Belgian crypto taxation, including CARF reporting starting in 2026.

The Belgian Crypto Tax System: 30% Diverse Income

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 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.
