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.
