How do we get a VAT number for our company? Should we register with the Dutch tax authorities?

VAT number

If you set up a business in the Netherlands, you must have it registered with the Trade Register of the Chamber of Commerce (KvK) . The Chamber of Commerce will pass on your details to the tax authorities. Once the tax authorities have registered your details, you will automatically receive a VAT number (also known as a VAT identification number).

If you start a one-man business, you will receive the VAT number immediately when you register with the Chamber of Commerce. If you set up a general partnership (vennootschap onder firma, VOF), limited partnership (commanditaire vennootschap, CV), partnership (maatschap) or legal entity, the tax authorities will usually send you your VAT number within five working days.

The VAT number

A VAT number (btw-number or btw-identification number) consists of 14 characters:

  • the NL country code;
  • followed by the Legal Entities and Partnerships Information Number (RSIN) or your Citizen service number (BSN);
  • supplemented with a code comprising three characters between B01 and B99.


You can find the RSIN number on the registration with the Trade Register of the Chamber of Commerce.

The tax authorities state your VAT number on the letters and forms they send to you. It may be that the number is mentioned without the country code NL. You are obliged to state your VAT number on all of your invoices.

VAT number de-registration

If you deregister your company from the Chamber of Commerce, you will be deregistered automatically from the tax authorities database and your VAT number will then be de‑registered. You will receive a written confirmation from the tax authorities about this.

How do you check if the VAT number of your client is valid?

If you want to check the validity of the VAT number of a business client who has a registered office in an EU country you can do this with the  VIES VAT number validation  of the European Commission. You can also check the name and address of clients of most member states with VIES.
