Understand VAT Treatment and the Reverse Charge Mechanism
Learn how Microsoft applies VAT based on your location and registered VAT ID.
When you provide a valid VAT identification number, Microsoft often applies the 'reverse charge' mechanism for cross-border business-to-business (B2B) transactions. This means Microsoft will not charge VAT on the invoice; instead, you are responsible for accounting for the VAT in your local tax return.
The 'GB' prefix simply identifies the VAT number as belonging to the United Kingdom. VAT treatment ultimately depends on your billing country, customer location, and VAT registration status.
Log in to the Microsoft 365 Admin Center using your administrator credentials.
Go to the 'Billing' section in the left-hand menu and select 'Billing accounts' or 'Your products'.
Check your tax information to ensure your VAT ID, including any country prefixes like 'GB', is entered correctly and validated.
Download your latest invoice from the 'Bills & payments' section and look for a note stating that the reverse charge mechanism applies.

Frequently Asked Questions
What does the GB prefix on my VAT number mean?
The GB prefix is the ISO country code used to officially identify a United Kingdom VAT registration number. It lets international billing systems know the origin of your VAT registration.
Why is Microsoft not charging VAT on my business invoice?
If you have provided a valid VAT number, Microsoft typically uses the reverse charge mechanism for B2B services. This shifts the liability, meaning VAT is not charged directly on the invoice and you must account for it yourself locally.
Can I add or update my VAT number after an invoice is generated?
You can update your VAT number at any time in the Microsoft 365 Admin Center, but the changes usually only apply to future invoices. For past invoices, you will need to contact Microsoft Support to request an adjustment.
