Applying for a VAT number and what to do with it
Written by Ilias3 min read
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.
