If you employ anyone under 21 years old you will no longer have to pay Class 1 secondary National Insurance contributions on earnings up to the new Upper Secondary Threshold (UST) for those employees.
This comes into effect from 6 April 2015 so be prepared to change the NI Category letters of those employees to ensure you’re paying the correct amount of NI contributions.
The Abolition of employer National insurance contributions for under 21’s section of GOV.UK has been updated and now includes more detailed guidance for employers, plus detail on the new category letters and rates
