• fill in the postal form on-screen, print and post it to HMRC

To apply online, you need a Government Gateway user ID and password. If you do not have a user ID, you can create one when you apply.

If you use the online form, you’ll get a reference number that you can use to track the progress of your form.

Before you start using the postal form

If you’re using an older browser, for example Internet Explorer 8, you’ll need to update it or use a different browser. Find out more about browsers.

You’ll need to fill in the postal form fully before you can print and post it. You can’t save a partly filled in form so you should gather all your information together before you start to fill it in.
