Going freelance in the Netherlands means joining the roughly 1.2 million ZZP'ers (zelfstandigen zonder personeel, self-employed without staff) who run an eenmanszaak, the Dutch sole-proprietorship. The tax system rewards entrepreneurs generously, but the deductions are being phased down, so the 2026 picture looks meaningfully different from a few years ago.
This guide breaks down exactly how your ZZP income is taxed, which deductions still exist, and runs a €50,000 profit example so you can see what actually lands in your account.
The eenmanszaak and the three boxes
Dutch income tax runs on a box system. Your business profit as a ZZP'er falls into Box 1 (income from work and home), taxed at progressive rates. Box 2 covers substantial shareholdings (relevant if you switch to a BV), and Box 3 covers savings and investments. As a sole proprietor, Box 1 is where almost everything happens.
Box 1 income tax rates
For reference, the 2025 Box 1 rates (under state pension age) were roughly:
- 35.82% on income up to about €38,441 (this band includes national insurance contributions).
- 37.48% on income between about €38,441 and €76,817.
- 49.50% on income above about €76,817.
The 2026 brackets are indexed and adjusted annually by the Belastingdienst (the Dutch tax authority), so confirm the exact thresholds before filing. The structure, three bands, top rate 49.5%, stays the same.
The deductions that make ZZP tax attractive
The reason self-employment is tax-favoured in the Netherlands is a stack of entrepreneur deductions applied before tax:
- Zelfstandigenaftrek (self-employed deduction), a fixed amount you subtract from profit if you meet the urencriterium (the 1,225-hour test). It has been cut steadily and sits near €1,200 for 2026, down from over €7,000 a decade ago.
- Startersaftrek (starter deduction), an extra €2,123 on top, available in three of your first five years as a new entrepreneur.
- MKB-winstvrijstelling (SME profit exemption), after the deductions above, 12.7% of your remaining profit is exempt from tax (2025 level; check the exact 2026 percentage).
These stack in order: profit, minus self-employed and starter deductions, then the 12.7% exemption on what's left, and only then the Box 1 rate applies.
Don't forget the Zvw healthcare contribution
On top of income tax, ZZP'ers pay the Zvw (Zorgverzekeringswet) income-dependent healthcare contribution, around 5.26% of your taxable income up to a capped maximum, invoiced separately by the Belastingdienst. It's easy to forget when budgeting, so include it in every set-aside calculation.
The worked example: €50,000 profit
Here's an established ZZP'er (past the starter window) with €50,000 profit who meets the hours criterion. Figures use 2025/2026 estimates for illustration; your exact bill depends on credits and final-year rates.
| Step | Amount |
|---|---|
| Gross profit | €50,000 |
| Less self-employed deduction | −€1,200 |
| Profit after deduction | €48,800 |
| Less MKB exemption (12.7%) | −€6,198 |
| Taxable Box 1 income | €42,602 |
| Income tax (blended ~36–37%, before credits) | ~€15,600 |
| Less general + labour tax credits | ~−€5,900 |
| Zvw healthcare (~5.26%) | ~€2,240 |
| Approx. total tax + Zvw | ~€11,940 |
| Approx. net income | ~€38,060 |
The two tax credits, the algemene heffingskorting (general credit) and the arbeidskorting (labour credit), do a lot of heavy lifting and are the reason effective rates on modest incomes are far below the headline 37%. Both taper as income rises.

The urencriterium: the 1,225-hour rule
Most of the best deductions, the zelfstandigenaftrek and startersaftrek, require passing the urencriterium: at least 1,225 hours spent on your business in the calendar year, roughly 24 hours a week. That includes admin, marketing and travel, not just billable work, but you must keep a credible record. Miss it, and you lose the self-employed and starter deductions (though the MKB exemption still applies).
Why the deductions keep falling
The Dutch government is deliberately narrowing the tax gap between employees and the self-employed. The zelfstandigenaftrek is on a legislated downward path toward roughly €900 by 2027. Practically, this means the pure tax advantage of being a ZZP'er is shrinking each year, a real factor if you're deciding between freelancing and employment, or between an eenmanszaak and a BV.
When to switch from eenmanszaak to a BV
As profit rises, the flat pass-through of the eenmanszaak eventually loses to the BV (besloten vennootschap), a private limited company. A BV pays corporate tax, 19% up to €200,000 of profit and 25.8% above, and you then draw income as a director's salary (subject to the gebruikelijkloonregeling, the customary-salary rule) plus dividends taxed in Box 2 at 24.5% up to about €67,000 and 31% above.
The crossover typically sits somewhere around €80,000–€100,000 of sustained profit, but it depends heavily on how much you reinvest versus draw out. Below that, the eenmanszaak's deductions usually win; above it, the BV's lower corporate rate and income-smoothing start to pay off.
The FOR is gone, plan your own pension buffer
The old fiscale oudedagsreserve (FOR), which let ZZP'ers set aside part of profit tax-deferred for retirement, has been closed to new contributions. That makes proactive pension planning more important: contributions to a qualifying lijfrente (annuity) remain deductible within your available jaarruimte (annual room), reducing Box 1 income now while building retirement savings. With no employer scheme behind you, this is one of the few remaining large deductions a ZZP'er can still control.
Deductible business costs to track
Beyond the headline deductions, ordinary business expenses reduce your profit before any of the entrepreneur reliefs apply. Common ones include:
- Workspace and equipment, software subscriptions and phone or internet used for work.
- Professional insurance, accountancy fees and bank charges on a business account.
- Business travel, and training that maintains or improves existing skills.
- A share of costs for a qualifying home office where the strict conditions are met.
Keep every invoice and separate business from personal spending, clean records are what let you claim confidently and survive a Belastingdienst review.
VAT (BTW) is a separate obligation
Most ZZP'ers must also register for and charge BTW (VAT), generally at 21%, filing quarterly. The kleineondernemersregeling (KOR) small-business scheme lets you skip charging VAT if turnover stays under €20,000 a year. VAT isn't your money, it flows to the Belastingdienst, so never treat collected BTW as income.
The tax credits that do the heavy lifting
Two credits shrink almost every ZZP'er's bill and explain why effective rates look nothing like the headline percentages:
- Algemene heffingskorting (general tax credit), a credit available to most taxpayers that reduces as income rises and phases out at higher incomes.
- Arbeidskorting (labour tax credit), a work-related credit that first rises with income, peaks, then tapers away for high earners.
Because both taper, your marginal rate on an extra euro of profit can be noticeably higher than the bracket rate suggests, an important nuance when deciding whether to take on that last project of the year or defer an invoice.
A quick low-profit example: €30,000
At €30,000 profit the picture is even friendlier. After the self-employed deduction and the 12.7% MKB exemption, taxable Box 1 income drops to roughly €25,300. With the general and labour credits applied, many starters at this level pay an effective rate well under 15% once credits and the starter deduction are counted, one reason the Netherlands remains attractive for people testing a freelance idea before committing full-time. Add the €2,123 starter deduction in your first years and the effective rate falls further still.
Provisional assessment and avoiding a year-end shock
The Belastingdienst often issues a voorlopige aanslag (provisional assessment) so you pay income tax in monthly instalments across the year rather than one lump sum. It's an estimate, if you under-forecast your profit you'll owe the balance later, sometimes with interest (belastingrente). Update your provisional assessment when your income changes, and keep the Zvw contribution in mind because it is billed separately from the income-tax assessment.
Practical tips for staying out of trouble
- Set aside 30–40% of every invoice for income tax, Zvw and VAT combined.
- Log your hours from day one to protect the urencriterium deductions.
- Build a pension, ZZP'ers have no employer scheme; consider an lijfrente (annuity) for extra deductions.
- Keep VAT separate in its own account so quarterly filings never squeeze cash flow.
Use the tax set-aside calculator to keep the right buffer, and the compare taxes by country tool if you're weighing the Netherlands against other bases.
The bottom line
For 2026, the eenmanszaak / ZZP structure remains genuinely tax-friendly at low-to-middle profit levels thanks to the self-employed deduction, starter deduction, 12.7% MKB exemption and generous tax credits, even as the deductions shrink year on year. Once profit is high and stable, running a BV can win. Model your specific numbers, respect the 1,225-hour rule, and always budget for Zvw and VAT alongside income tax.
