Mm vat mtd connection has lapsed and I can't re-connect, getting not authorised message?

Hi there, Yvonne. The not authorised error message you received occurs when your connection has expired.

Please know that HRMC requires you to reauthorise your MTD connection every 18 months to maintain secure access. To resolve and reconnect it, please follow the steps below:

1. Open QuickBooks and follow the on-screen prompts for reauthorising your connection.
2. Log in using your HMRC credentials in the pop-up window.

Once completed, QuickBooks will automatically reconnect this, allowing you to continue submitting your VAT returns without interruption. For more information, check out this article: Set up MTD (Making Tax Digital) for VAT in QuickBooks.
