Have been trying to authorise a MTD VAT client on our normal (non-agent services) government gateway and it keeps failing. Spoke to HMRC who advised that any MTD VAT registered clients need to be authorised through the agent services account and won't work the 'old' way. Non-MTD clients should still be authorised in the 'old' way through the government gateway. Has anyone else encountered this / is this correct? Know HMRC have lots of new recruits presently!
