Belgium is not a tax haven and doesn't pretend to be. Income tax hits 50% early, and 2026 brought a new capital-gains tax. But there's no general wealth tax, US Social Security stays untaxed here, and the rules — while heavy — are predictable. Plan with real numbers.
Figures verified 16 September 2026| Taxable income bracket | Rate |

The first €11,180 is covered by the personal tax allowance (2026). On top of the federal tax, your commune adds a surcharge of 0–9% of the tax due — the national average is about 7% (non-residents pay a flat 7%). Filing runs through MyMinfin, FPS Finance's online portal.
