How much of your profit do you keep net in 2026? Work it out. It is an estimate.
From your profit comes first the self-employed deduction (if you meet the hours criterion). Then the SME profit exemption of 12.7% comes off. On the rest you pay income tax in box 1. The general tax credit and the labour credit then come off that. Finally the Zvw health contribution is added (4.85% in 2026). What is left is your net income.
This tool uses the 2026 rates and shows every step. It is an estimate. Your situation can differ, and it is not tax advice.
