Taxcalc is throwing up 17.02% Capital Allowances during the first period of self employment from May 2010 to 31 March 2011. It was only bought 2 days before the year end, but I don't see why that should matter. It's 145 C0 and I've double checked all the accounting and basis period dates.
Oh its the number of days in the short, first period of accounts. Strange how it threw up the word 'hybrid' though. Ok, panic over; serves me right for not typing up my capital allowance computations. Tim
