What tax rate do freelancers pay? Box 1 brackets explained

Income tax in the Netherlands is progressive — the more you earn, the higher the percentage you pay. If you're self-employed, you're taxed on your business profit in Box 1. This guide explains the brackets, the top rate, and the tax credits that reduce what you actually owe.

The three progressive brackets#

Dutch Box 1 income tax has roughly three tiers. The exact boundaries and rates adjust every year, so I'll give you the rough structure and point you to the official figures.

For 2025/2026 (rounded; check belastingdienst.nl for the precise current amounts):

• First bracket (lowest income): roughly 36–37% on income up to around €35,000
• Second bracket (mid income): roughly 36–37% on income from roughly €35,000 to €76,000–€78,000
• Top bracket (high income): roughly 49.5% on income above €76,000–€78,000

These are marginal rates — you don't pay 49.5% on all your profit, only on the portion that falls in that top band. And crucially, before tax is applied, you've already deducted your business costs and your entrepreneur deductions (zelfstandigenaftrek, startersaftrek, MKB-winstvrijstelling). So your effective rate is much lower.

A worked example: profit to tax#

Let's say your business profit for 2025 is €50,000. Here's how it flows through:

1. Profit: €50,000
2. Minus zelfstandigenaftrek (2025): €2,470
3. Taxable after zelfstandigenaftrek: €47,530
4. Minus MKB-winstvrijstelling (12.7%): roughly €6,036
5. Taxable after MKB: roughly €41,494
6. Tax at brackets: On €41,494:
   • First ~€35,000 at roughly 36–37% = ~€13,000
   • Remaining ~€6,494 at roughly 37% = ~€2,400
   • Subtotal tax: roughly €15,400
7. Less heffingskorting (general credit, ~€3,200): ~€12,200
8. Less arbeidskorting (up to ~€5,500): roughly €6,700

Your actual bill on €50,000 profit is roughly €6,700 — an effective rate of about 13.4%, far below the 49.5% top bracket.

The key takeaway: deductions and credits do the heavy lifting. The brackets tell you the marginal rate, but your real tax burden is shaped by how much you can deduct before you hit them.

How the MKB-winstvrijstelling saves you money#

Before the brackets are even applied, your taxable profit gets an automatic 12.7% deduction (in 2025/2026) via the MKB-winstvrijstelling (small-business profit exemption). This alone can save you €1,000–€5,000+/year.

In the example above, the MKB deduction cut your taxable profit from €47,530 to ~€41,494 — instantly lowering your tax bill. Learn more about the MKB-winstvrijstelling.

Tax credits: heffingskorting and arbeidskorting#

After your tax is calculated from the brackets, you get two main credits:

• Heffingskorting (general tax credit): roughly €3,200+ per year. Nearly everyone gets this; it's an automatic reduction.
• Arbeidskorting (labour credit): up to roughly €5,500+ per year if you have labour income (which self-employed income counts as). This is tapered if you earn very high income.

These credits are the reason your effective tax rate (the percentage of profit you actually pay) is so much lower than the marginal bracket you're in.

Will I get audited at my tax bracket?#

No single bracket triggers an audit. But the Belastingdienst does look for red flags: sudden, huge jumps in profit, suspiciously round deduction amounts, or unrealistic urencriterium claims (1,225-hour work records). Read more about audit risk.

How it changes when you earn very high income#

If your profit pushes above roughly €76,000–€78,000, you hit the top marginal bracket of 49.5%. But this only applies to the marginal income — the slice above the threshold. And the credits are tapered (reduced) at very high incomes, so your effective rate creeps up but never hits 49.5% on all your profit.

For most freelancers, the first and second brackets are where they stay. It's usually only scaling tech startups or established consulting firms that crack the top bracket regularly.

Self-employed vs employment income#

If you earn both salaried income and self-employed income (Box 1), they're taxed together on the same return at the same brackets. Your employer will have already withheld income tax from your salary; your aangifte reconciles both streams.

Planning your income#

Knowing the brackets can inform business decisions:

• Below €35,000 profit? You're in the first bracket. Adding clients that push you into the second bracket (36–37%) is still worth it.
• Approaching €76,000–€78,000? The jump to 49.5% is real, but it only applies to income above the threshold. Growing to €80,000 costs you ~50 cents more per euro earned, not the full 49.5%.

The marginal-rate thinking helps you avoid the trap of "I don't want to earn more because it'll push me into a higher bracket."

Frequently asked questions#

The Box 1 brackets might look steep on paper — 49.5% is high — but remember: deductions, credits, and the MKB-winstvrijstelling all happen before the brackets bite. Your effective tax rate is almost always far lower. ZZP Belasting tracks your profit throughout the year so you can see exactly how much you'll owe, brackets, credits and all.
