When does my employer pay Class 1A National Insurance on benefits/expenses

The deadline for Class 1A National Insurance payments is 19^th July by post, and 22^nd July if paying electronically.

All employers are required to pay the Class 1A National Insurance liability, but there are two different deadlines, depending on how they pay. Employers have until 19^th July if paying by post, but this is extended to 22^nd July if they are paying by electronic bank transfer.
