How is crypto taxed in Belgium?

Belgium crypto tax rules changed sharply in 2026. Before then, private investors who managed their assets normally usually paid no tax on gains, while speculative gains could be taxed at 33%. A new capital gains tax on financial assets now covers crypto too, applying a 10% rate to gains realised from January 1, 2026.

What is the Belgium capital gains tax for crypto in 2026?

The tax was part of the federal government's January 2025 coalition agreement. Parliament approved it in early April 2026, and the law of April 6, 2026 was published in the Belgian Official Gazette on April 21, 2026. It applies retroactively to gains realised from January 1, 2026.

Crypto-assets fall within the broad group of financial assets, alongside shares, bonds, funds, currencies and investment gold. The tax applies when an asset is transferred for payment. Gifts and inheritances are excluded.

What is the Belgium crypto tax rate?

The general rate is 10% on net gains. The first 10,000 euros of gains in a year are exempt per taxpayer, but you need to report your gains to claim it. If you do not use the exemption, up to 1,000 euros a year can be carried forward, to a maximum exemption of 15,000 euros.

Only gains from 2026 onward count. For assets bought earlier, the starting value is generally their value at December 31, 2025. If your original purchase price was higher, you may keep using it for five years. Losses can only offset gains of the same category in the same year and cannot be carried forward.

The old rules have not disappeared. Gains that come from speculation, or from managing assets outside the normal management of private wealth, are still taxed as miscellaneous income at 33%. Professional traders face professional income rules instead.

How is bitcoin tax in Belgium collected?

Belgian banks and other intermediaries must withhold the tax from June 1, 2026, unless the investor opts out and reports the gains in the annual tax return. Because the law came late, gains from January 1 to May 31, 2026 were not withheld automatically, though investors could ask for voluntary withholding until August 31, 2026.

Gains realised through foreign platforms or outside the banking system, which covers much crypto activity, must be declared by the taxpayer in the tax return. Keeping full transaction records from your exchanges and wallets makes this easier.

Rules differ by country and change often. Check the tax authority or a qualified professional for your own situation.
