Good to know

Dates are the standard HMRC and Companies House deadlines. A company's first accounts and accounting periods can have different dates, PAYE paid by cheque is due on the 19th, and if a deadline falls on a weekend or bank holiday, pay early. Your confirmation statement is due within 14 days of its review date each year. The calendar file includes a reminder a week before each deadline.
