Forex Trading Tax in Belgium 2026 — Complete Guide

Forex Tax Treatment in Belgium

Belgium has banned the distribution of CFDs, binary options, and forex to retail consumers since 2016 (Royal Decree). Belgian residents can only trade forex through non-Belgian entities, and capital gains from speculative trading may be taxed at 33% as 'diverse income'.

Belgium does not have a general capital gains tax. Forex/CFD profits sit in one of three buckets: tax-exempt 'normaal beheer', 33% diverse income, or fully taxable professional income.

What Counts as Taxable?

Most Belgium residents need to declare the following types of trading income:

• Realised forex/CFD capital gains. Profits from closing positions during the tax year.
• Dividend-equivalent payments. Cash adjustments paid by your broker on long share-CFD positions when the underlying issues a dividend.
• Carry / swap interest received. Positive overnight financing credited to long carry-trade positions is normally taxable as financial income.
• Cashback, rebates and bonuses. Cash incentives paid by the broker may be reportable as miscellaneous or financial income.
• Crypto CFD profits. Profits from cryptocurrency CFDs are taxed under the same rules as other CFDs (this is different from spot crypto, which usually has its own treatment).
• Foreign exchange differences. Gains or losses from holding foreign-currency balances may need to be reported separately when converted back to your home currency.

Professional vs Retail Trader — Tax Implications

Frequent, leveraged, or income-replacing trading is almost always reclassified as professional income, meaning progressive income tax (25%-50%) and social contributions.

How to Declare Forex Income in Belgium

1. 1

   Download your annual statement from each broker (and convert all amounts to EUR using year-end FX rates if your account is in another currency).

2. 2

   Calculate net realised profit or loss for the tax year — buy/sell pairs only (unrealised positions are usually excluded, except for mark-to-market regimes).

3. 3

   Add carry/swap interest, dividend-equivalent payments, and any cashback or rebates.

4. 4

   Open Aangifte personenbelasting (Tax-on-web) on the FOD Financien / SPF Finances portal.

5. 5

   Enter the totals in the capital-gains / investment-income section and indicate the source country of each broker.

6. 6

   Pay any balance owed by the deadline (Mid-July of the following year (paper); end September (online)) and keep the receipt and broker statements with your records.

Record Keeping Requirements

Keep all statements and a trade log. The classification of activity is heavily fact-based, so contemporaneous records are essential to support the chosen tax position.

• Annual broker statements (PDF and machine-readable formats)
• Trade-by-trade ledger with timestamps, instrument, and P&L
• Year-end account valuation (mandatory for wealth-tax regimes)
• Proof of any foreign tax already paid, to claim against home liability under double-tax treaties
• FX-conversion rates used to translate amounts into EUR

Recommended Accountants & Software

Tax-on-web is the official portal. Given the complexity of the speculative-vs-normal classification, a Belgian belastingconsulent / fiscaliste is strongly advised.

We do not endorse any single product. For active traders we generally recommend a local advisor who has direct experience with CFD/derivative reporting and any cross-border passporting that applies to your broker.
