Capital gain rules in Belgium

Capital gain taxation depends on the holding period. If the property is sold more than 5 years after purchase, the capital gain is tax-free. If sold within 5 years, it is taxed at 16.5% (plus municipal surcharges). The period is calculated from notarial deed to notarial deed.

Capital gain calculation

Capital gain = sale price - (purchase price + 25% flat-rate acquisition costs + documented works). The purchase price is increased by 5% per year of ownership. If the result is negative, there is no taxation.

Exemptions

The sale of a primary residence is always exempt from capital gains tax, regardless of the holding period. This exemption does not apply to investment properties (rented or second homes). After 5 years, investment properties are also exempt as an individual.

In a company, capital gains are always taxed (corporate tax at 25%), with no 5-year exemption.

Optimisation strategies

Hold for more than 5 years to avoid capital gains tax. Keep all renovation invoices (they reduce the taxable gain if sold within 5 years). Consider the difference between individual and company ownership. Consult our rental taxation guide for a complete fiscal strategy. A rental management software helps track all documents.
