Hi eddytea,
Thanks for joining us here on the Community!
There are a few things to check when we come across this message, please first see that the VAT registration number is entered correctly within the settings (Taxes > Edit VAT > Edit settings), and that this is formatted in numbers only without spaces or letters.
If this is correct, please get back to us below and advise if this the first time you'll be submitting VAT via MTD in QuickBooks, and whether you're submitting for your own company or as an agent on behalf of a client.
Thanks :)
