Preparing for MTD for VAT (businesses)    
Signing up for MTD for VAT
Before you can use MTD from any application your VAT records must be migrated on HMRC's computers from HMRC's old system to HMRC's MTD system. You have to initiate this migration by going to the Sign up for MTD page on HMRC's web site. After you have signed up it can take up to 72 hours before your records are moved. HMRC usually send a confirmation email.

Checking you are signed up for MTD for VAT
You can check you are signed up for MTD by signing into your business taxes page on HMRC's web site. This will have an MTD section if you are signed up and will show your VAT number and your submitted and outstanding MTD VAT returns.

Granting authority
You do not need to enter your government gateway user ID and password every time you access your VAT records via an MTD enabled application such as VT. Instead, you just have to enter your credentials once. The MTD application is then issued with an authorisation code by HMRC which it keeps and stores for up to 18 months. This process is known as granting authority.

To grant authority, choose the Grant Authority command or caption in the VT application you are using. This will open a special page on HMRC's web site in your normal web browser. Please then follow the instructions on HMRC's web site. At the end of the process you will be asked to copy and paste an authorisation code into VT. The process is simple and straight forward.

VT is not able to provide support on the use of HMRC's web site. If necessary, please contact the HMRC online services helpdesk.
