Before Easy MTD can retrieve Income Tax and VAT information from HMRC or submit anything to HMRC for a business or taxpayer, it must be connected with HMRC.
How to Connect
The connection process is started by clicking a Connect link on the Taxpayers page, Businesses page or if you are an agent, on the Agents page, or by clicking the Yes button in the "Not Connected to HMRC" window. Following this, the "Allow your software to connect with HMRC" web page is opened in the default browser along with the Easy MTD "Connect with HMRC" window. Follow the steps presented in the browser then, at the end of the process, copy the authorisation code and paste it into the Code box in the Easy MTD "Connect with HMRC" window.
Failed Connections
The number one reason why making a connection with HMRC fails, is because the incorrect HMRC sign-in credentials were used. The HMRC sign-in credentials MUST be associated with the business or taxpayer you are performing the connection for, or the agent assigned to the business or taxpayer. Using HMRC sign-in credentials that do not match the business, taxpayer or agent will result in the connection failing (despite the authorisation code being accepted) and you will be continually presented with the "Not Connected with HMRC" window until the correct credentials are used.
Other possible reasons for being unable to connect with HMRC are described in the following Knowledge Base article:
Why can't I connect Easy MTD with HMRC?
Expiry
If you have previously connected Easy MTD with HMRC for a business, taxpayer or agent and you are being prompted to connect again, it is likely the connection has expired. Connections normally expire after 18 months.
