Netherlands ZZP Tax Calculator 2026

The order of operations is the whole calculation

Dutch freelance tax is not a rate applied to profit. It is a chain, and each link changes what the next one sees:

1. Revenue minus business expenses gives winst, the profit.
2. The ondernemersaftrek comes off — €1,200 of zelfstandigenaftrek, plus €2,123 of startersaftrek for a starter. Both require the hours criterion.
3. The mkb-winstvrijstelling of 12.7% comes off what is left — note that it is a percentage of profit after step 2, not of the original profit.
4. The box 1 scale applies to the remainder.
5. Above €78,426 the tariefsaanpassing adds tax back, because steps 2 and 3 are only allowed to relieve at 37.56%.
6. The heffingskortingen come off the tax, not the income.
7. The Zvw contribution is charged separately on the taxable profit.

Reverse steps 2 and 3 and you get a different answer, which is why a lot of quick estimates of Dutch freelance tax disagree with each other.

The two credits are measured on different profits

This is the detail most worth knowing, and the one most likely to be wrong in a spreadsheet you built yourself.

The arbeidskorting — maximum €5,685, withdrawn at 6.51% from €45,592 and gone by €132,920 — is calculated on arbeidsinkomen. The Belastingdienst defines that for an entrepreneur as winst uit onderneming vóór ondernemersaftrek en mkb-winstvrijstelling: profit before the reliefs.

The algemene heffingskorting — maximum €3,115, withdrawn at 6.398% from €29,736 and nil from €78,427 — is calculated on verzamelinkomen, which is income after them.

Using the post-relief figure for both is the natural mistake, and it does not fail safely: it inflates the arbeidskorting and so understates the tax, because across most of the range in between the credit is shrinking as income rises.

Where the marginal rate peaks — and it is not at the top

The headline top rate is 49.50%. It is not the highest rate a Dutch freelancer faces on an extra euro of profit.

Three things withdraw at once as profit rises past €78,426: the arbeidskorting is still tapering at 6.51%, the algemene heffingskorting has only just finished, and the tariefsaanpassing starts clawing back the reliefs at 11.94%. Stack those on the scale rate and the effective marginal rate on profit runs above 60% through that band, then falls back once the arbeidskorting reaches zero at €132,920.

Move the revenue field above and below €78,426 to see it. The pattern — a hump in the middle rather than a peak at the top — is the same shape we found in Spanish regional scales, where the region with the highest headline rate is mid-table for a normal freelance income.

The 1,225-hour rule is worth less than its reputation

The urencriterium is the best-known threshold in Dutch freelance tax: spend at least 1,225 hours a year on the business and you qualify for the ondernemersaftrek. The Belastingdienst also requires that you spend more time on the business than on other work, a condition waived if you were not an entrepreneur in one of the five preceding years.

What it is actually worth now is modest. The deduction it gates is €1,200, relieved at 37.56%, and missing the criterion leaves the mkb-winstvrijstelling untouched. On a mid-range profit the difference is a few hundred euros a year — real, but no longer the cliff edge that older guidance describes. For a starter it matters more, because €2,123 of startersaftrek rides on the same test.

What this does not model

A resident ZZP'er below AOW age, box 1 only. Not included: box 3 wealth tax, partner allocation, mortgage interest relief, the expatriate ruling, the meewerkaftrek and stakingsaftrek, investment allowances, the FOR successor arrangements, or your own health insurance premium — which sits on top of the Zvw contribution rather than replacing it.

BTW is a separate system and is not part of the figures above. The €20,000 kleineondernemersregeling threshold, which must hold for both the year you register and the year before, is covered alongside every other country's in our VAT and GST registration thresholds guide.

For what the same income keeps elsewhere, the five-country net income comparison runs the tax side, and because the Netherlands sits well above the EU average on prices, the cost of living adjusted salary converter is the other half of any comparison with a cheaper country.
