1. Eenmanszaak and ZZP: Dutch independence
ZZP status (Zelfstandige Zonder Personeel) is used by over 1.4 million independents in the Netherlands in 2025.
Eenmanszaak (sole proprietorship) is the simplest legal form in the Netherlands. Registration is done directly at KvK (Kamer van Koophandel, Chamber of Commerce) in 24 to 48 hours, without minimum share capital, without notarial act. The founder immediately receives their KvK-nummer (Chamber of Commerce number) and BTW-id (VAT number). ZZP status is not a separate legal form but a mode of exercising the Eenmanszaak applied to independents without salaried personnel — it is the common designation for freelancers, consultants, service providers.
Fiscally, Eenmanszaak is transparent: profit is integrated into the founder's personal income and taxed at Inkomstenbelasting (income tax) per the 2025 progressive scale: 36.93% up to €75,624 (combining merged brackets 1 and 2 in 2025), 49.5% beyond. The Dutch system distinguishes three fiscal boxes: Box 1 (work and business income), Box 2 (substantial shareholder income 5%+), Box 3 (savings and investment). For Eenmanszaak, taxation falls under Box 1.
Independents benefit from two major flat deductions. Zelfstandigenaftrek (independent deduction) applies to ZZPs working at least 1,225 hours per year on their activity: €2,470 deduction from taxable profit in 2025 (progressively decreasing per the trajectory toward €900 in 2027). Startersaftrek (starter deduction) adds during the first 3 years of activity: additional €1,765 per year, applicable maximum 3 times in 5 years. Combined, these deductions allow a ZZP launching with €30,000 profit to reduce taxable to €25,765 — annual tax saving of approximately €1,500 to €2,000.
The 1,225-hour criterion
Zelfstandigenaftrek and startersaftrek are conditional on a 1,225-hour threshold per year dedicated to independent activity (urencriterium). Keeping a precise record of worked hours is essential — Belastingdienst can audit this criterion. For independents combining ZZP and employment, the criterion imposes in practice at least 50% of total time on ZZP activity, excluding « accessory » ZZPs.
