ROS calculation

I am using ROS and it looks like to me that some of the calculations relating to share options are not being calculated correctly, and, in fact, reducing my tax liability. Any ideas on what to do here?

You might need to post more detailed info than that for people to comment meaningfully.

Sounds like you are not entering the options info in the correct place. As far as I recall they should go in the Benefit in Kind section of income.
