Thank you for your help. Sorry, I am new to this, so are we in week 53? I am stumped because on PAYE 2010 software I can add a week 53 upto 5th April but on PAYE Basic Tools for 2011 onwards they won't let me add week ending 8th April for week 1. Is this because I haven't done a year end for 2010/11 and how can I do that until I resolve this final week??
