Thanks asdfg - I forgot to mention it was actually overtime that was the big bug-bear for me rather than the BIK amount, but as with BIK, that overtime was listed within the P60 earnings, so it does count in calculating allowable pension contributions I think, regardless of the PRSA provider's form confusions.
I heaved a sigh of relief when I got my section 30 receipt today, but I suppose the pension providers might still send it back saying it's wrong...
Somehow I always seem to manage to just get the pension payment in on time, then relax a bit too far, thinking "whew, that's done at last", next thing, I will nearly forget to do the ROS return and payment in time for 16 Nov... must remember to set myself some proper reminders...
