Reauthorise with HMRC

To submit VAT Returns to HMRC, you must authorise Sage Accounting. You then need to reauthorise every 18 months. This is for data security purposes. You'll also need to reauthorise if you:

• Disconnect from MTD
• Change your VAT Registration Number

You sign in to the government gateway as part of this process.

Reauthorise with HMRC

1. Go to Settings, then Business settings.
2. Select Accounting Dates & VAT.
3. In the Making Tax Digital section, select Reconnect, then Authenticate. This opens the HMRC website.
4. Select Continue, then enter your Government gateway User ID and Password.
5. Select Grant Authority.
6. In Sage Accounting, when you see a confirmation message at the bottom of the page, you're done.
