    You get an acknowledgement of receipt. Please note that this acknowledgement is not the confirmation letter, which would give you the right to operate the vehicle on the road. For more information about the confirmation letter, see section 9 below.

    You have the option to move on directly from the acknowledgement-of-receipt page to the submittal of a Car tax return. To do so, press the File car tax return button.  After that, all the entries you made on the Declaration of use will show pre-filled on the Car tax return

    You can see the Declaration (a pdf file) in your MyTax Mailbox. Print it out on paper. This is your confirmation letter, to be kept in your vehicle when you drive it.
