Common expat situations

Not sure which tool to start with? Pick your situation.

New job offer

You just received a Dutch job offer

Start with the job offer decoder to understand what your gross salary actually means in take-home pay — including vakantiegeld and 13th month. Then check the 30% ruling calculator to see if you qualify for the expat tax benefit, which can add €500–1,500/month in net income. Finally, run the health insurance guide to see whether your employer's contribution covers the real cost.

Going freelance

You're starting or switching to ZZP

Use the ZZP tax calculator to estimate your netto inkomen and how much to set aside monthly. If you have children, your ZZP income directly affects your kinderopvangtoeslag — run that calculator too, since the toeslag percentage changes with income. As a self-employed worker you also have no employer health contribution, so budget carefully using the health insurance cost guide.

Relocating with family

You're moving to the Netherlands with children

The childcare benefit calculator should be your first stop — kinderopvangtoeslag can cover up to 96% of daycare costs, making a significant difference to your family budget. Use the city comparison guide to pick a location with good international schools and manageable woonkosten. Then factor in health insurance costs for your whole household — each adult needs their own policy.

Employment vs freelance

You're deciding between a job and going ZZP

Decode the employed offer first with the job offer decoder — employers often bury value in pension contributions and holiday budgets. Then model the freelance alternative in the ZZP calculator: as ZZP you need a rate roughly 30–40% higher than employee gross to break even after sick pay, pension, and health insurance. There's also a middle path — umbrella (payrolling) — where you set your own rate but keep employment benefits. The contracting rate converter shows all three side by side.

Contracting via umbrella

You're offered a rate via an umbrella or payroll company

Umbrella companies (payrollbedrijven) take an hourly rate from the client, deduct their fee (1.5–5%), pay all employer charges, and pay you a gross salary. What looks like a great rate can net very differently depending on the margin. Use the umbrella company calculator to enter your client rate and see net take-home — and instantly compare what the same budget would yield as ZZP or secondment. Also checks whether your rate is above the schijnzelfstandigheid risk threshold.

Considering a 4-day week

You want to work less — but need to know the real cost

Going from 5 to 4 days cuts your gross by 20%, but the net impact is smaller than you think — Dutch progressive tax absorbs part of the drop. On a €70k salary the real monthly cost is roughly €550–650, not €1,000. Use the 4-day week calculator to see your exact number. If you have the 30% ruling, check whether your pro-rated salary stays above the minimum threshold first — losing it costs far more than a day off saves.

Frequently asked questions

Kinderopvangtoeslag in 2026 ranges from 96% of childcare costs (lowest incomes) down to 36.5% (higher incomes). The maximum subsidised hourly rate is €10.25 for daycare and €9.12 for BSO (after-school care). Use the childcare benefit calculator to find your exact percentage based on your household income.
The 30% ruling (30 procent regeling) lets qualifying expat employees receive 30% of gross salary tax-free. To qualify you must be recruited from abroad, earn above €48,013 taxable salary (2026 threshold), and have lived more than 150km from the Dutch border before hiring. The ruling lasts up to 5 years. Use the 30% ruling calculator to check your eligibility and estimate savings.
Basic health insurance (basisverzekering) costs €135–185/month in 2026 depending on insurer. The mandatory own risk (eigen risico) is €385/year. Lower-income residents can receive zorgtoeslag to offset the cost — up to around €127/month. The health insurance guide breaks down costs and zorgtoeslag eligibility.
ZZP income is taxed in Box 1: 35.75% up to €38,883, 37.56% up to €78,426, and 49.5% above (2026 rates). Your effective rate is much lower thanks to the zelfstandigenaftrek (€1,200 in 2026) and MKB-winstvrijstelling (12.7% profit exemption). A ZZP earning €60,000 gross typically pays an effective rate of 22–28%. Use the ZZP tax calculator to estimate your specific situation.
Vakantiegeld (holiday allowance) is a mandatory 8% annual bonus on your base salary, paid each May. When an offer states a salary "including vakantiegeld", divide by 1.08 to get your base — e.g. €65,000 incl. vakantiegeld = €60,185 base + €4,815 holiday pay. The job offer decoder handles this calculation automatically.
Register with the Dutch Chamber of Commerce (KVK) online or in person — takes 15–30 minutes and costs around €50. You receive a KVK number and the KVK notifies the Belastingdienst automatically. If your annual revenue will exceed €20,000, also register for VAT (BTW). You can start invoicing clients immediately after registration.
An umbrella company (payrollbedrijf) lets you work with your own clients at your own rate while remaining formally employed — you keep WW unemployment insurance, sick pay, and pension accrual. The umbrella invoices the client, deducts its fee (typically 1.5–5%) plus all employer social charges (~22%), and pays you a gross salary from what remains. ZZP gives higher net income at the same client rate, but you bear all risk yourself. Secondment means the agency finds the clients for you. Use the umbrella company calculator to compare net take-home across all three contract types side by side.
