Download ABC SA800 - previous years

Our Self Assessment products are fully functional (except for actual submission to HMRC) in evaluation mode: you can download and install the software for free, and enter your data to check that you like the product (and see your tax liability calculation). When you are ready to submit to HMRC, purchase a licence to enable submission.

Note that in order to submit to HMRC you will need to have a Government Gateway ID and have enrolled it for the Self Assessment service (where HMRC send an activation code in the post).

Since HMRC change the rules and forms each year, we produce dedicated software for each tax year: please download the software for the year you require.

ABC SA800 2019 - for tax year ending 5 April 2019


ABC SA800 2018 - for tax year ending 5 April 2018


ABC SA800 2017 - for tax year ending 5 April 2017


Note that HMRC only supports electronic submission for a particular tax year up to 4 years after the end of that tax year - so electronic submission is not possible for years prior to 2016-17. You can submit via paper forms, which are available on the HMRC website.
