Details of the Self Assessment Tax Return Pages - for 3rd party software developers

These pages are intended to help 3rd party software developers create their products using draft versions of the 2007-08 SA Tax Returns which can be viewed as they are developed.

Please note: This section of our website is intended for use by 3rd party software developers only.

Due to recommendations made by Lord Carter of Coles’ review of HMRC On-line services, the guidance for developing 3rd party software and substitute returns for the two tax years differs. Guidelines for the current year’s (2006/07) and the developing year’s (2007/08) Return and supplementary page are available.
