A client has employment income of £65,777 and a gain chargeable event of £36,154 on a policy held for 29 years. I hadn't considered top slicing relief as client is a HR taxpayer but Taxcalc has top slicing relief as £5,603.22. I've run through the calculations and still come back to zero, logically I think it's because the taxpayer would have received £500 staring rate per year (although that hasn't been around for 28 years??). £500 x 28 (ignoring this year as it's dealt with in the comp) = £14,000 @ 40% is £5,600 so where does the £3.22 come from? I've also considered that there has been a loss of PA this year but I can't get my head around this one. Am I barking up the wrong tree?
