Starting as a ZZP'er in the Netherlands: KVK registration, BTW returns, the 2026 deductions, and the DBA rules

Anyone who freelances in the Netherlands is a ZZP'er (zelfstandige zonder personeel, a self-employed professional without staff). Becoming one is quick. You fill in an online form, visit an office of KVK (Kamer van Koophandel, the Chamber of Commerce) once, and pay €85.15. The real work starts the same day. From your first invoice you deal with BTW (Dutch VAT) and a return every quarter. The DBA rules decide whether your client contract counts as freelance work or as hidden employment, and the Belastingdienst (Tax Administration) enforces them again. And nobody arranges sick pay, unemployment cover or a pension for you any more. This guide covers the registration step by step, the BTW system, the 2026 entrepreneur deductions, the DBA rules, and the gaps you now cover yourself.

Whether you may work for yourself follows from your residence status. Citizens of the EU, EEA and Switzerland need no work permission at all. Everyone else needs a residence document whose endorsement allows arbeid als zelfstandige (self-employed work), or the dedicated self-employed person permit. Working self-employed without the right permission is not allowed, for you or for your client. Check the endorsement on the back of your residence card first; the work rights by residence permit guide explains what every endorsement means and lists the routes per permit.

You can register up to 3 months before your start date, and no later than 1 week after it. The registration has four steps:

• Fill in the registration form online at kvk.nl. You log in with DigiD, so you need a BSN (citizen service number) first. The form asks for a trade name, a short description of your activities in Dutch, and a Dutch business address. Your home address is allowed.
• Make an appointment at a KVK office. Registration is not possible without the appointment. Bring a valid passport, ID card or residence document.
• Pay the one-off registration fee: €85.15 in 2026. The amount changes each year with inflation, and it is a deductible business cost.
• Receive your KVK number. If you register within 1 week before or after your start date, you get the number straight away at the appointment.

KVK passes your details to the Belastingdienst automatically; you do not register there separately. Within 2 weeks you receive two numbers by post. The btw-id (VAT identification number, format NL123456789B01) goes on your invoices, quotes and website. The omzetbelastingnummer (turnover tax number) is only for your own contact with the Belastingdienst. Once the btw-id letter arrives, you can invoice.

This registration is for an eenmanszaak, the legal form almost every starting freelancer chooses. It has no setup formalities beyond KVK, and you can employ staff later despite the name. The trade-off is liability: with an eenmanszaak you are personally liable for business debts, with your private money and belongings. The main alternative, a bv (private limited company), makes the company liable instead of you, but it runs through a civil-law notary and has its own tax rules. For a normal freelance start without big financial risks, the eenmanszaak is the standard choice.

The standard BTW rate is 21% and applies to most freelance services. A reduced 9% rate exists for a fixed list of goods and services, such as food, medicines and books, and a 0% rate applies to most cross-border transactions. Some sectors are exempt from BTW, including most healthcare and education. If an exemption or the 9% rate might apply to your work, check it before your first invoice, because the wrong rate is your problem, not your client's.

Dutch law sets invoice requirements (factuureisen). Every invoice must show:

• The invoice date and an invoice number. Numbers must run in sequence, without gaps.
• Your name, address, btw-id and KVK number.
• Your client's name and address. For a business client in another EU country, also their VAT number.
• What you delivered, the quantity, and the delivery date.
• The BTW rate you applied and the BTW amount.

You file the BTW return (aangifte omzetbelasting) online in Mijn Belastingdienst Zakelijk, the business portal of the Belastingdienst, with DigiD or eHerkenning. For most freelancers the period is a quarter. The deadline for filing and paying is the last day of the month after the period; the return explanation on Business.gov.nl lists the exact dates. Note two rules. You must file for every period, even a quarter with zero turnover; that is a nihilaangifte (nil return). And the Belastingdienst sends no bill and no payment link after you file: you calculate the amount in the return and transfer it yourself. Missing the deadline leads to a naheffingsaanslag (additional assessment).

The KOR (kleineondernemersregeling, small businesses scheme) is a voluntary BTW exemption for businesses with a turnover of at most €20,000 per calendar year. Inside the scheme you charge no BTW, file no BTW returns, and cannot deduct the BTW on your own business purchases. You apply with a form in Mijn Belastingdienst Zakelijk, at least 4 weeks before the return period in which you want it to start; the KOR conditions are on Business.gov.nl. If your turnover passes €20,000 during the year, you must tell the Belastingdienst immediately and charge BTW from that moment on. The KOR fits freelancers with mostly private customers, because private customers cannot deduct BTW and so pay your full price. It is less attractive with business clients, who can deduct the BTW you charge anyway, and in years with big purchases, because you lose the BTW deduction on them. A separate EU version exists for small businesses that also sell in other EU countries, with an extra cap of €100,000 turnover across the EU.

Your profit (turnover minus business costs) is taxed as income in box 1, together with any salary from a job. There is no separate company tax for an eenmanszaak. The return itself, the rates and the M-form for your migration year are covered in the income tax guide. What is specific to entrepreneurs is a set of deductions that shrink your taxable profit before the normal rates apply:

The urencriterium is 1,225 hours per calendar year spent on your business. All business hours count: acquisition, administration and building your website too, not only billable hours. Normally you must also spend more time on the business than on other work, but starters are excused from that second condition. The 1,225 hours are not reduced when you start halfway through the year, so a late-year start rarely qualifies in year one. Keep a simple hours log from the first week, so you can show the hours later; it takes minutes and protects the deduction.

Do not build long-term plans on the zelfstandigenaftrek: the government is phasing it down, to €900 in 2027. A worked example for 2026: you start this year, meet the hours criterion, and make €40,000 profit. The zelfstandigenaftrek (€1,200) and startersaftrek (€2,123) bring the profit to €36,677. The mkb-winstvrijstelling removes 12.7% of that (€4,658), leaving €32,019 of taxable profit. Almost €8,000 of your profit is not taxed.

One more assessment comes with the profit: the inkomensafhankelijke bijdrage Zvw (income-dependent healthcare contribution). Employees have it paid by their employer; entrepreneurs pay it themselves after the tax return. In 2026 the rate is 4.85% of your income, up to an income of €79,409. In the example above that is about €1,553. It comes on top of your monthly health insurance premium, not instead of it.

Schijnzelfstandigheid (false self-employment) means working as a ZZP'er in a relationship that is really a job. What your contract says does not settle it; what counts is how you work in practice. The Belastingdienst weighs all circumstances of the work together. Signals that point to employment: the client decides how, when and where you work; you do the same work as employees next to you; the work is a structural part of the organisation; you must do it personally and cannot send a replacement; you carry no commercial risk; you work for one client for a long time and do nothing to find others. No single point is decisive. A high rate or a second client does not automatically make you self-employed.

For years these rules were barely enforced. That ended on 1 January 2025, when the enforcement pause (handhavingsmoratorium) was lifted. 2025 was a transition year without penalty fines; since 2026 fines are possible on top of the assessments, and corrections in cases without intent go back at most to 1 January 2025. The client carries the heaviest risk: a client who should have run payroll owes the payroll taxes afterwards. But you are exposed too. If your work is reclassified as employment, you were no entrepreneur for that income, and you can be made to repay the entrepreneur deductions through an additional assessment. You may also gain something: a falsely self-employed worker can claim a real employment contract, with the protections listed in the employment contracts guide.

Two practical points follow. First, modelovereenkomsten (model agreements once approved by the Belastingdienst) are on their way out: no new ones are approved, and existing ones may be used until 31 December 2029, and only when the real work matches the text. A model agreement is no shield when the practice looks like employment. Second, when a client says 'we no longer work with ZZP'ers' for a role, that is usually risk management: the role would be embedded work under the client's direction, exactly what the rules treat as employment. Before you accept a long assignment, run the government's online check of the working relationship, linked from the false self-employment page above, and ask the client to do the same. Client and contractor are responsible together.

An employee who falls ill keeps being paid, builds unemployment rights, and often gets a pension arranged by the employer; the employment contracts guide lists those protections. As a ZZP'er, none of this exists by default. When you are ill, your income stops that day. When an assignment ends, there is no WW (unemployment benefit). The gaps, and what you can do about each:

• Sickness and disability: an AOV (arbeidsongeschiktheidsverzekering, disability insurance) is voluntary and you arrange it yourself. If you come straight from employment, you can continue insurance through UWV (the employee insurance agency), but only if you request it within 13 weeks after your employee insurance ended. The insurance options for the self-employed page lists the routes, including donation circles (schenkkringen) and crowdsurance initiatives.
• Pregnancy: self-employed women can get the ZEZ maternity benefit through UWV.
• Unemployment: no WW. If the business fails and your income falls below the social minimum, the gemeente (municipality) can support you under the Bbz (Besluit bijstandverlening zelfstandigen, social assistance for the self-employed).
• Pension: the state AOW builds automatically for every resident. Everything above it you save yourself, for example through a retirement annuity (lijfrente).
• Health insurance: stays mandatory, exactly as for employees, and the Zvw contribution over your profit comes on top. See the health insurance guide.

Mandatory disability insurance is planned, but it is not law. A bill for a basic disability insurance for the self-employed (Wet BAZ) is in the legislative process. The current plan on the Rijksoverheid page about it: a premium of 5.4% of income up to about €171 per month, a benefit of 70% of your former income up to 100% of the minimum wage, and a waiting period of 2 years. The government states the figures can still change, and the start date is not final. Until then, no insurance means no income when you cannot work.

• Keep your records for at least 7 years: invoices, bank statements, contracts, agendas and your hours log. Records about immovable property keep for 10 years. Digital records must stay digital and readable; a printed copy alone does not count.
• A separate business bank account is only mandatory for a bv or nv, not for an eenmanszaak. Most freelancers open one anyway, because your administration must show clearly which income and spending is business. The bank account guide covers opening an account; ask the bank about a business account if you want your trade name on transfers.
• Plan the yearly rhythm: four BTW returns, one income tax return in spring, and the separate Zvw assessment. An accountant or bookkeeping software is not required by law, but most freelancers use one of the two; a bookkeeper for an eenmanszaak is a normal deductible cost.

You work full weeks for one client, in their office, in their team, on their laptop, and the assignment keeps being extended. This is the classic risk profile the Belastingdienst looks for. Fix it before the Belastingdienst reclassifies the relationship. Steps that make the relationship more self-employed in practice: agree on a result instead of on hours and presence, plan your own working times, use your own equipment, arrange that you may send a replacement, and take other clients next to it. If the work is honestly a job, the clean solution is an employment contract, possibly part-time next to your business. Run the online assessment tool together with the client; the outcome protects you both when the facts match it.

Your BTW duty does not wait for your first invoice. From registration on, every period needs a return, including a quarter in which you earned nothing; that zero return takes two minutes in Mijn Belastingdienst Zakelijk. Many starters wait for a paper letter and miss the first deadline. Log in to the portal in your first month and note all filing deadlines for the year. If you have already missed one: file and pay immediately anyway. A naheffingsaanslag for the period can follow, and reacting fast keeps it as small as possible.

In a job, tax leaves the payslip every month. As a ZZP'er nothing is withheld: you invoice gross amounts, and the income tax arrives later. After your first tax return, two demands arrive close together. The final assessment over your first year. And a voorlopige aanslag (provisional assessment): an advance on the current year, based on your first year's profit, spread over the year in instalments. The separate Zvw assessment joins them. Freelancers who spent their gross turnover in year 1 get into real trouble at this point. The fix is the callout above: set aside a fixed share of every paid invoice from month one. And keep the voorlopige aanslag realistic in Mijn Belastingdienst: lower it when your profit drops, raise it when you grow, so the advance follows reality instead of last year.

A KVK registration is not a work permission. Whether you may work self-employed follows from your residence status alone, and invoicing without the right status is illegal work, with consequences for you and your client. If your endorsement blocks self-employment, do not start invoicing. The routes out, such as a dedicated self-employed person permit from the IND or a status that brings free labour-market access, depend on your permit; check your exact endorsement in the work rights guide before you send anyone an invoice.

Two guides continue from here. The income tax guide explains the return itself, the M-form for the year you moved, and the deadlines. And if freelancing is one option next to a job search, the finding a job guide covers the employee route while your Dutch is still growing.
