API says VAT-registered user is not registered

Hello!

I have a user who tells me they are registered for VAT (and they can see the VAT dropdown when explaining bank transactions). However the API reports that their company sales_tax_registration_status is "Not Registered".

The user also tells me their FreeAgent account was provided by their accountant and they cannot see a Settings → VAT Registration page.

How can I use the API to determine that they are in fact registered for VAT?

Many thanks!

Yours,
Andrew Stewart
