Employer NICs for under-21s

As announced in the 2013 Autumn Statement, from 6 April 2015 employers will no longer be required to pay Class 1 secondary NICs on earnings paid up to the Upper Earnings Limit to any employee under the age of 21. This will apply to both existing employees and to employers taking on new staff. No individual’s state pension entitlement will be affected by the measure.
