Every month, employers pay PAYE and National Insurance online by the 22nd (a cheque must arrive by the 19th), and construction contractors send their CIS return by the 19th. Company dates assume a 31 March year end; yours run from your own year end, so work them out on our limited company page. When a payment date falls on a weekend or bank holiday, make sure the money reaches HMRC by the working day before.
