1. Profit and the zelfstandigenaftrek 2026
A zzp'er (zelfstandige zonder personeel) is a self-employed person without staff, usually with a sole trader business (eenmanszaak). Profit is turnover minus business costs, both excluding VAT. If you meet the hours criterion of 1,225 hours a year, € 1,200 zelfstandigenaftrek comes off (€ 600 at AOW age), never more than your profit. Starters get € 2,123 startersaftrek on top, three times in their first five years; then the deduction may exceed the profit.
