The self-employed deduction (zelfstandigenaftrek) is a fixed annual deduction from business profit for entrepreneurs who meet the hours criterion. The deduction is being phased down each year: from €3,750 in 2024 to €900 in 2027. You are entitled to it when you spend at least 1,225 hours per year on your business. Together with the SME profit exemption, it significantly reduces the tax burden for self-employed entrepreneurs.
