Hello there, @jmldn1. Thank you for posting here on the Community page.
I've got some steps to help you resolve the HMRC connection issue, and I'll ensure you'll be able to submit your VAT return. I'm happy to help you.
Let us first enable MTD before submitting VAT returns to HMRC. Then, for QuickBooks to interact with HMRC, you must first authorize it. You can follow the steps below:
- Click on the Gear icon, then Account and Settings.
- Go to the Advanced tab, then select the Making Tax Digital header to expand the section.
- Click on Learn how to connect, then click on Let's go on the Get started with digital tax page.
Once MTD has been enabled in QuickBooks. Follow the steps below:
- After clicking on Let's go, you'll be directed to the HMRC page, as shown below. Click Continue to sign in.
- Enter your HMRC credentials to sign in.
- Click on Grant authority to continue. The authorization process will begin.
Then you'll get the message 'You're connected to HMRC' as shown below. Click the Continue button. When the process is complete, click Take a look.
