ZZP (Zelfstandige Zonder Personeel) is the Dutch form of self-employment, highly popular among workers from Poland and other EU countries. Working as a freelancer in the Netherlands offers great flexibility and higher earnings, but requires proper legal and administrative preparation. This comprehensive guide covers everything you need to know before choosing ZZP in the Netherlands.

What is ZZP in the Netherlands?

ZZP literally means Zelfstandige Zonder Personeel – self-employed without staff. It is the most common form of sole proprietorship in the Netherlands. A ZZP-er (as this type of worker is called) provides services directly to companies or agencies, invoicing for completed work.

Over 1.1 million people work as ZZP-ers in the Netherlands, representing around 13% of the total workforce. Among Polish workers in the Netherlands, ZZP is especially popular in construction, logistics, production, welding, automotive, and metalworking sectors.

ZZP vs. employment contract – key differences

Before deciding on ZZP, it is important to understand the key differences compared to a standard employment contract (dienstverband):

  • Hourly rate – ZZP-ers typically earn 20–40% more gross than salaried employees in the same position
  • Taxes – you file taxes independently with the Belastingdienst (Dutch Tax Authority)
  • Holiday and sick leave – not automatically provided; you must fund these yourself
  • Insurance – no automatic social security coverage; you must arrange your own
  • Independence – you can work for multiple clients simultaneously

How to become a ZZP-er in the Netherlands – step by step

Registering as a ZZP-er in the Netherlands is relatively straightforward but requires completing several specific steps. Here is the complete procedure:

Step 1: Register with KvK (Kamer van Koophandel)

KvK is the Dutch Chamber of Commerce. Registration is mandatory and costs €75.60 (one-time fee). You can register:

  • Online through kvk.nl (available in English)
  • In person at a KvK branch (appointment required)

After registration you receive a KvK number (8 digits), which must appear on every invoice you issue. KvK automatically forwards your details to the Belastingdienst.

Step 2: BTW (VAT) number

The Belastingdienst automatically assigns you a BTW (VAT) number after KvK registration. The BTW number consists of the letters NL, your RSIN number, and the code B01. Include it on all invoices alongside your KvK number.

Important: If your annual turnover does not exceed €20,000, you may qualify for the KOR scheme (Kleineondernemersregeling) and be exempt from charging VAT – a significant simplification when starting out.

Step 3: Dutch business bank account

While there is no legal requirement to have a separate business account, it is strongly recommended for cleaner bookkeeping and a professional image. Popular options for ZZP-ers include ABN AMRO, ING, Rabobank, and challenger banks such as Bunq or Revolut Business.

Step 4: Liability insurance (Aansprakelijkheidsverzekering)

Business liability insurance (AVB) is not legally mandatory but is required in practice by most companies and agencies before signing a contract. It typically costs between €15 and €50 per month depending on your industry and coverage level.

Step 5: Client contract (Overeenkomst van Opdracht)

Every assignment should be confirmed by a written contract – the Overeenkomst van Opdracht (OvO). It defines the scope of work, rate, payment terms, and conditions. Since 2016, the DBA Act (Wet Deregulering Beoordeling Arbeidsrelaties) has been in force to prevent bogus self-employment. In 2025, the Belastingdienst resumed active enforcement of DBA compliance checks.

ZZP taxes in the Netherlands – how to file

Tax filing is one of the most complex aspects of working as a ZZP-er. Here are the key points explained.

Inkomstenbelasting – income tax

ZZP-ers pay income tax (inkomstenbelasting) under Box 1, which covers income from work and business activities. In 2025, the rates are:

  • Up to €75,518: 36.97%
  • Above €75,518: 49.50%

However, as a ZZP-er you can take advantage of several deductions that significantly reduce your taxable income.

Key tax deductions for ZZP-ers

  • Zelfstandigenaftrek – self-employment deduction, €2,470 in 2025 (being phased down to €900 by 2027)
  • MKB-winstvrijstelling – additional 13.31% exemption on profit after zelfstandigenaftrek
  • Startersaftrek – extra deduction of €2,123 per year for the first 3 years of business (max 3 out of the first 5 years)
  • Arbeidskorting – employment tax credit, up to €5,052 per year
  • Algemene heffingskorting – general tax credit, up to €3,362 per year

BTW – VAT filing

If you do not use the KOR scheme, you must charge and remit BTW (VAT). The standard rate in the Netherlands is 21%, with reduced rates of 9% or 0% for certain services. VAT is filed quarterly or monthly through the Mijn Belastingdienst Zakelijk portal.

Advance tax payments

The Belastingdienst may require advance tax payments (voorlopige aanslag) for the current year. It is worth proactively requesting these to avoid a large lump-sum payment after annual filing.

Insurance for ZZP-ers

One of the biggest risks of working as a ZZP-er is the lack of automatic insurance coverage. As a ZZP-er, you are solely responsible for your financial security in case of illness, accident, or incapacity to work.

Disability insurance (AOV)

Arbeidsongeschiktheidsverzekering (AOV) is insurance against long-term incapacity to work. It is voluntary but critically important – especially for those doing physical work. Costs range from €100 to €400 per month depending on your age, profession, and insured income level.

An alternative is Broodfonds – a ZZP-er mutual fund where participants financially support each other in case of illness. It is cheaper than AOV and growing in popularity.

ZZP and pension

ZZP-ers are not subject to mandatory pension schemes (pensioen), so independent retirement savings are essential. Options include:

  • Lijfrente – annuity pension insurance with tax deduction
  • Banksparen – saving in a dedicated bank account with tax deduction
  • AOW – Dutch state pension (available to all Dutch residents)

ZZP rates – how much can you earn?

ZZP rates vary considerably by industry, experience, and location. Below are indicative gross hourly rates for popular trades (2025):

  • MIG/MAG welder: €20–28/h
  • CNC operator / turner: €22–32/h
  • Bricklayer / plasterer: €18–26/h
  • Electrician: €24–35/h
  • CE truck driver: €18–25/h
  • Car mechanic: €20–30/h
  • Roofer: €20–28/h
  • Forklift operator: €16–22/h

Remember that from your ZZP rate you must independently cover taxes, insurance, holiday days, and gaps between assignments. As a rule of thumb, your ZZP rate should be at least 30–40% higher than the equivalent salaried position.

Pros and cons of working as a ZZP-er

Advantages of ZZP

  • Higher net earnings – with good tax planning, a ZZP-er can earn more than a salaried employee
  • Flexibility – you decide when and for whom you work
  • Independence – you can have multiple clients simultaneously
  • Career control – you build your own brand and reputation
  • Tax deductions – startersaftrek, zelfstandigenaftrek and other deductions can significantly reduce your tax bill
  • No corporate constraints – more freedom to negotiate your own terms

Disadvantages of ZZP

  • No paid holiday or sick leave – every day off means lost income
  • Self-bookkeeping – you must maintain records or hire an accountant
  • Income uncertainty – no guaranteed steady income
  • Insurance costs – AOV, liability and other insurance can cost several hundred euros per month
  • DBA risk – the Belastingdienst may challenge your ZZP status if the work relationship resembles employment
  • Harder to get a mortgage – banks typically require at least 3 years of business history

ZZP and bogus self-employment – DBA risk

Since 2025, the Belastingdienst has been actively enforcing checks on so-called schijnzelfstandigheid (bogus self-employment). If you effectively work like a salaried employee (fixed hours, single client, no ability to delegate work), your ZZP status may be challenged. The consequences can be serious – for both the ZZP-er and the client.

To avoid problems, ensure that:

  • You work for more than one client (or have the freedom to do so)
  • You own your own tools or equipment
  • Your contract defines a result, not just working hours
  • You can subcontract the work to someone else

Practical tips for ZZP-ers from Poland

  • Hire a Dutch boekhouder (accountant) – costs around €50–150/month, but tax savings typically far exceed this expense
  • Use invoicing software – Moneybird, e-Boekhouden, or Twinfield are popular, affordable solutions
  • Set aside tax money as you go – we recommend saving 30–35% of every payment in a separate account
  • Check rates annually – zelfstandigenaftrek and other deductions change every year
  • Get a DigiD – the digital ID needed for all communication with Dutch government services
  • BSN (Burgerservicenummer) – the Dutch equivalent of a national ID number, required to register a business

Frequently asked questions about ZZP in the Netherlands

Can a Polish citizen start ZZP in the Netherlands?

Yes, EU citizens (including Polish nationals) have the full right to establish ZZP activity in the Netherlands under the same rules as Dutch citizens. You only need a BSN number and a registered address in the Netherlands.

How much does ZZP registration cost?

The one-time KvK registration fee is €75.60 (2025). There are no monthly fees for simply maintaining a KvK entry.

Do I need to speak Dutch to work as a ZZP-er?

Dutch language skills are not a formal requirement. Many formalities can be handled in English. However, for dealings with the Belastingdienst and reading contracts, language knowledge is very helpful – consider hiring a Dutch-speaking accountant.

Online KvK registration typically takes 1–3 business days. Your BTW number arrives by post or electronically within a few weeks of registration.

Does a ZZP-er pay social security contributions?

ZZP-ers in the Netherlands do not pay into the Dutch social security system for sickness or pension coverage in the way salaried employees do. They do pay income tax, and can voluntarily take out AOV disability insurance and private pension plans.

Summary – is ZZP the right choice for you?

ZZP in the Netherlands is an excellent option for experienced professionals who value independence and want to earn more. It does, however, require solid preparation: understanding the tax system, arranging appropriate insurance, and maintaining accurate financial records.
