Built for FOD Financien crypto tax filing
Belgium changed in 2026. A 10% capital gains tax now reaches disposals that normal management used to leave untaxed, and the older classification still decides when a heavier regime applies instead.
10% capital gains tax
In force since 1 January 2026 for capital gains on financial assets, with crypto-assets and NFTs named in scope. An annual exemption applies before the rate bites, and losses in the same category offset within the year.
31 December 2025 base
Assets acquired before the new tax are measured against their value on 31 December 2025, not their purchase price. Kryptos holds that snapshot for every holding so the gain is computed from the right base.
33% on speculative
Diverse inkomsten / Revenus divers stays flat at 33% where activity is speculative rather than normal management. Computed against net gains in that category, with same-category loss offset within the year.
Tax-on-Web codes
Codes 1192 (speculative gains), 1193 (speculative losses) and equivalent professional codes mapped automatically so your return goes into the right boxes.
