Our client has a business tax gateway account, has signed up for MTD VAT, can log into that account and all is fine, no issues. We have a Agent Services account and have generated the link for them to authorise us as we have done with plenty of others, no issues. When client clicks link to accept us they are being asked to verify their identity by supplying a passport or driving licence number - they are a Limited company. It doesn't ask them to do that when they log into the account, just when accepting our link.
Has anyone come across this before and if so how to deal with it? My client has tried using their personal information and it is being rejected. I have read online that they might need to verify their identitiy in order to accept our authorisation and the client has tried using their own passport but it is just being rejected. How should they verify a business account?
