I am preparing accounts for a small business which began 1/10/2017. I am taking the accounts up to 31st March 2018 to fit in with tax year going forward. So a 6 month accounting/basis period this year. Theres a van worth £5,000 which I am going to claim CAs on. The client is wanting to claim the max tax rebate possible which will mean carrying a loss back to 15/16 tax year, where it will be set against tax paid when they were employed on paid PAYE.
Am I restricted to only claiming £2,500 CAs on this first tax return?
