Is anyone having trouble connecting to HMRC for MTD?

You can reauthorize QuickBooks Online (QBO) to connect with HMRC, Mary.

Beforehand, could you please specify if you encountered an error connecting your HMRC to MTD, such as QuickBooks no longer being authorized to connect? If so, this issue could stem from an expired connection (after 18 months), incorrect credentials, unauthorized agent services, or mismatched VAT registration numbers.

To reauthorize QBO, here's how:

1. Go to Taxes.
2. Click the Edit VAT dropdown, then Edit Settings.
   
    

   
3. Turn off MTD, and reconnect with MTD credentials.
   
    
    
4. Hit Save.

Ensure your credentials are specific to MTD and not general Government Gateway credentials.

For more guide, you can consult this article: Fixing MTD (Making Tax Digital) issues in QuickBooks Online.

Additionally, I'll provide this article for reference when reporting to HMRC to ensure accuracy and avoid missed or duplicated VAT: VAT exceptions and reports in QuickBooks Online.

If that's not the case, you can revisit this thread. The Community team is always available to provide a tailored solution regarding your VAT or any QBO-related concerns.
