I'm not sure if this has been addressed before, but could there by a prompt every month to remind you to update HMRC notices (tax codes). I sometimes run a payroll having forgotten to go to the HMRC tab and check on any tax code updates.
There's a setting called HMRC which allows you to select to automatically download and apply HMRC notices - does that work for you? We have it set but it doesn't work for us :(
