To ask HMRC to cancel your Duty Stamps Scheme registration, you can either:
use the online service
fill in the form on-screen, print and post to HMRC
To use the online service, you’ll need the Government Gateway user ID and password you used when you registered. If you do not have a user ID you can create one when you use the service.
If you use the online service, you’ll get a reference number that you can use to track the progress of your form.
Information you’ll need to fill in this form
your Duty Stamps Scheme registration number
your UK excise or SEED registration number
the serial numbers of any duty stamps you’re returning
Before sending your application to de-register for the Duty Stamps Scheme, return all unused freestanding (Type A) stamps in your possession, or in the possession of anyone you’ve authorised to act on your behalf, to the HMRC appointed print contractor. To arrange for collection, call the Contractors Customer Support line on Telephone: 0845 121 4411.
Once you’re de-registered, you are no longer authorised to incorporate the label stamp (Type B) design specification into labels. HMRC advises you to destroy all copies of the (Type B) design specification in your company’s possession, or the possession of anyone you’ve authorised to act on your behalf.
This will stop someone using the specification fraudulently in your name.
