How refunds are calculated

You can cancel registration online if you have a mySAGOV account and you want to:

In both these cases you don't need to surrender the number plates.

To cancel online:

  1. Log in to your mySAGOV account
  2. Select Vehicle list in the Vehicles section
  3. Select Details alongside the registration number of the relevant vehicle
  4. Scroll down and under Payments, select Cancel registration

Create an account if you don't already have one.
