Hi
I am trying to transmit the first return and get this message:
Vat return submission to HMRC failed.
By Gateway : Authentication Failure. The supplied user credentials failed validation for the requested service.
Can you please advise as I have already enrolled for MTD.
It also states:
MTD is now Live . Please first enroll for MTD within your HMRC Tax Account, then link your Tax Account [here]
Do you also need to enroll for tax account?
Thanks
Anette
