# What happen if I don’t have a valid Tax ID?

When you are going to fill in all the boxes on “Billing info”, **all the mandatory fields (\*) must be filled in.**

**You can leave a box blank, but if you do it, [a 21% VAT will be charged](https://support.dataslayer.ai/information-about-the-tax-vat?hsLang=en).**
