ZZP Belasting Calculator 2025

The Netherlands has one of Europe's largest freelance workforces with over 1.2 million ZZP'ers — Zelfstandigen Zonder Personeel, meaning self-employed without staff. ZZP workers are fully responsible for calculating and paying their own income tax. Key tax benefits available to ZZP'ers include the zelfstandigenaftrek (self-employed deduction of 3,750 euros in 2025) and the MKB-winstvrijstelling (SME profit exemption of 13.31% of profit). These deductions require you to meet the urencriterium — working at least 1,225 hours per year in your business. This calculator accounts for all applicable deductions and computes your quarterly BTW obligation alongside your annual income tax liability.

⚠️ Vereenvoudigde berekening op basis van 2025 tarieven. Zelfstandigenaftrek en MKB-winstvrijstelling vereisen minimaal 1.225 uur werken aan je onderneming (urencriterium). Raadpleeg een belastingadviseur voor je persoonlijke situatie.
