Hi,
You can use your existing business tax account to enrol for MTD but firstly you will need to remove your old MTD enrolment from the account.
Login to your business tax accoun, select Manage Account at the top of the screen, then select Remove a tax duty or scheme and then follow the on screen instructions..
Once the old enrolment has been removed you can add your new enrolment with your new VAT number.
If you have any problems please contact our VAT team.
