Problem reported by Russell Gunn 4 weeks ago
I have been trying to re-authorise the VAT submissions with HMRC but it is not working., I have asked this before and have tried different ways of signing in but it it still not working??
SolvedHi Russell,
I have taken a look and can see you are experiencing the invalid authorisation error indicates that HMRC are rejecting the credentials you've used to authorise for VAT. In this case, you can trial and error the different set of Gov Gateway credentials you have. If successful, the error message should not appear.
Otherwise, you will need to contact HMRC who will be able to share the correct User ID.
