For years I've been submitting monthly season train ticket expenses, and when doing so have made the assumption that VAT is charged on these tickets at 20% So, when submitting my monthly expenses to the accountant for a train ticket of e.g. £960, have submitted expenses of £800 net, £160 VAT, £960 gross. I am on FRS, and the tickets were for about 6 months paid for using my personal credit card before subsequently being paid for on company debit & credit cards.
So by incorrectly assuming VAT was applied, have I lost out in any way e.g. increased corporation tax bill?
