1.  Have you signed the affected company up to Making Tax Digital for VAT?

• You are informed that you can no longer make manually entered online VAT submissions.
• You can see previous VAT return submissions made from AccountEdge for the affected company.
• The company's VAT Registration Number in AccountEdge matches that of the government gateway account for the affected company.

• In short, are you using the correct HMRC business tax account with which to authorise AccountEdge for MTD?

• Check and confirm that your HMRC business tax account is not linked to any other HMRC services or accounts, such as personal self assessment accounts, or similar.
