Why isn’t my VAT ID accepted?

Did you already add your VAT ID to your Temper profile, but still see a message saying it hasn’t been entered or that the system isn’t recognizing it? Follow these steps to fix it.

Step 1: Check if the number is correct

When you register as a freelancer, the Belastingdienst (Tax Administration) gives you two different numbers:

• Your VAT tax number (omzetbelastingnummer) is used for your tax returns and communication with the Tax Authority.
• Your VAT ID (btw-identificatienummer) is the one you use for invoicing and to share with clients, that’s the one we need from you.

You can find both numbers in Mijn Belastingdienst Zakelijk. Your VAT ID always starts with NL, followed by 9 digits, the letter B, and then 2 more digits (for example: NL123456789B01).

Step 2: Check if your VAT ID is active

We regularly verify whether your VAT ID is active. It’s possible that the Tax Administration has temporarily deactivated it, for example, if you forgot to declare your taxes.

Log in to Mijn Belastingdienst Zakelijk to make sure your VAT ID is still active. If it’s not, contact the Tax Authority at 0800-0543.

Step 3: Check if your address matches

Make sure the invoice address in your Temper profile matches the address linked to your VAT ID. Also check that the business name in your profile matches the name under which your VAT ID is registered.

If you’ve recently moved, don’t forget to update your billing details in your Temper profile as well.

Step 4: Everything looks correct, now what?

If the number is valid and all details match, try re-entering your VAT ID in your Temper profile, that often solves the issue.
