Applying for a VAT number and what to do with it
Written by Ilias Aarrass7 min read · Published on · Last reviewed on 
In short
You do not apply for a VAT number separately: after registering with the Chamber of Commerce the tax authorities post your VAT ID and turnover tax number within a few working days to two weeks.
- The VAT identification number is for the outside world: it is required on your invoices and on your website.
- The turnover tax number is only used towards the tax authorities; for a sole trader it embeds your citizen service number.
- Since 2020 the VAT ID no longer contains a citizen service number, for exactly that privacy reason.
- You check an EU client VAT ID through the European VIES service before you reverse-charge the VAT.
When you register with the KvK, it automatically registers you with the tax authorities. Shortly after you receive your VAT numbers. Many starters get confused because you get two. This article explains the difference and what to do with them.
Which two numbers do you get?
You receive a turnover tax number and a VAT identification number (VAT-id). You use the turnover tax number in your communication with the tax authorities, for example for your return. You use the VAT-id externally: on your invoices and website. The VAT-id no longer contains your citizen service number, so your privacy is better protected.
What do you use the VAT number for?
You're required to put your VAT-id on all your invoices and on your website. Customers and the tax authorities can use it to verify that you're a registered entrepreneur. If you work with foreign business clients, they check your number via the VIES check, and you check theirs.
When are you liable for VAT?
Almost every entrepreneur is liable for VAT and must charge and remit it. There are exceptions, such as the KOR exemption and certain exempt sectors like parts of healthcare and education. If you're unsure whether to charge VAT, check your situation before sending your first invoice.
What if your details change?
If you move or change your business name, you report this to the KvK, which usually passes it on to the tax authorities. Do check that your new details are correct everywhere, because an incorrect VAT number on your invoice can cause problems for your clients.
Two numbers, two purposes
After registering you receive two different numbers from the tax authorities, and they are often confused. The VAT identification number is for the outside world: it goes on your invoices and website. The turnover tax number is for contact with the tax authorities themselves, for instance when filing.
Since 2020 the VAT ID no longer contains your citizen service number. So always use the VAT ID on invoices and your site, never the old turnover tax number that embeds your BSN.
- Register with the Chamber of Commerce; it passes your details to the tax authorities. See registering with the Chamber of Commerce, and if you come from abroad starting as an international freelancer.
- Within a few working days to two weeks you receive your VAT ID and turnover tax number by post.
- Check that your filing period is correct; the default is quarterly.
- Put the VAT ID on your invoices and website, and quote it to EU clients together with the reverse-charge wording.
- From your first period you file returns, even nil ones. See your first VAT return.
Two numbers, two purposes
The tax authorities give you two numbers that look alike but serve different purposes. Mixing them up is the most common mistake on a first invoice.
| Number | Used for | Public? |
|---|---|---|
| VAT identification number | On your invoices and website, and for EU clients | Yes, meant to be shared |
| Turnover tax number | Your VAT return and contact with the tax authorities | No, it contains your citizen service number |
| Applying | Not needed separately: it follows your registration | By post, within a few working days to two weeks |
| Checking a client | Through VIES, the EU register | Keep a screenshot as evidence |
Frequently asked questions
How do I get a VAT number?
Not separately: you register with the Chamber of Commerce, which passes your details to the tax authorities. Within a few working days to two weeks your VAT ID arrives by post.
What is the difference between the VAT ID and the turnover tax number?
The VAT ID is for external use: invoices, website, EU clients. The turnover tax number is used towards the tax authorities. The old number embeds your BSN, so it never belongs on an invoice.
Must my VAT ID appear on my website?
Yes, if you offer services or products through your site. Put it with your company details, together with your Chamber of Commerce number.
May I invoice before receiving my VAT ID?
Preferably not with VAT on it, since without a valid VAT ID your client cannot deduct that VAT. If you cannot wait, consult the tax authorities or invoice once the number arrives.
I earn only a small side income. Do I still get a VAT ID?
Usually yes; VAT entrepreneurship applies quickly. The tax authorities may ask questions first. If you stay below 20,000 euros turnover, consider the small business scheme straight away.
How do I check whether a VAT ID is valid?
Through the European VIES check. That matters especially when reverse-charging to an EU client: reverse-charge to an invalid number and the VAT stays at your expense.
