My client incorporated his business on 1st April 2022, and we decided to transfer his sole trader VAT registration - had I known what a headache it would be, I probably wouldn't have suggested it but the transfer process has now been finalised.
My question is about the limited company's Government Gateway account. I can't seem to add VAT to the account, presumably because it's still linked to the old (sole trader) GG account. Initially the error message was "the information does not exist ... or it has already been used to request access to this tax", and more recently it says "could not confirm the business, the information you provided does not match the details we have ..." (I've tried various combinations of VAT registration date, last VAT Return figures, etc but nothing seems to work).
Has anybody come across this scenario recently, does my client continue to use the old GG details to file his VAT Returns via Quickbooks?
Also when I access the limited company's VAT account via my ASA, I can use the section for clients who have "signed up or opted out of MTD" so presumably the MTD registration has been transferred across during the transfer process, has anybody come across this?
Grateful for any assistance and thoughts, thank you.
