To connect Sage Accounting to HMRC to submit your VAT Returns using MTD, you need to authenticate your software with HMRC.
HMRC will decide if you meet the exemption criteria. To avoid potential penalties, check eligibility on their website for general VAT enquiries.
If you’re getting an error preventing you authenticating, refer to our guide on the unable to authenticate with HMRC error.
The connection lasts for 18 months before you have to reauthorise Sage Accounting with HMRC.
