Exit tax · Belgium

Leaving Belgium.

Exit tax since 2026. When you lose Belgian residence, Belgium calculates the latent gain on your financial assets accrued since 1 January 2026 and taxes it at 10%, or on a sliding scale for a stake of 20% or more. It is collected only if you sell within 24 months of leaving, and canceled otherwise. Gains from before 2026 are out of scope.

Income tax on the published 2026 rules. Social contributions, most deductions and treaties are not modeled. Figures are for a non-US single filer. Wealth tax, an exit and your passports are added when you run the engine on your own numbers. Not advice. Residence rules change often. Verify before acting.
