HMRC will say, yes, it was an easy and forgivable mistake to make, to put a figure in the wrong box. But they will then say, did you not think it very odd that the form generated a rebate? They will say that a reasonable person would have realised something was wrong and gone back and checked. Now, if you can honestly say that you double and triple checked it and still couldn't find anything wrong, they might regard it as an innocent error and let you off the penalty.
I think 15% is high, but you won't get less than 10%. I would revise the draft offer letter to include 10%, but will be interested to hear what other contributors suggest too.
