Before you start

This form is interactive, one that you complete on screen, and you must use Adobe Reader to complete it. Downloading Adobe Reader is free. Download the latest version of Adobe Reader.

HMRC are creating new versions of their forms that do not depend on Adobe Reader. Whilst this work is in progress the following methods can be used to ensure the form will download or open in Adobe Reader:

  • whatever browser you are using, review your settings to make Adobe Reader the default program for opening PDF documents
  • Windows users should right click on the form link then select ‘Save target as’ or ‘Save link as’
  • Mac users should right click on the form link then select ‘Save linked file as’
  • save the form - the recommended place is in the documents folder
  • using Adobe Reader you can open the form

If the form still does not open, contact the Online Services helpdesks.
