Capital Gains Tax 2026
Since January 1, 2026, Belgium taxes capital gains on financial assets. The gain is calculated using the FIFO method (First In, First Out). For assets held before 2026, the market value on December 31, 2025 replaces the original acquisition price. Fees and commissions are not deductible.
