Ruth Owen, director general of personal tax at HMRC, said: “HMRC appreciates that some employers might be daunted by the change, but they don’t need to be. HMRC is on hand to offer help and support, and we are taking a pragmatic approach, which includes no in-year late filing penalties for the first year.”

Employers that do not report the final payments they make to staff for the tax years 2012-2013 and 2013-2014 by 19 May in the following tax year will be charged a late filing penalty, charged at £100 per 50 employees and accruing for each month (or part month) that a return remains outstanding after 19 May.
