The rules about who is liable to pay Class 1A NICs on benefits,
including car and fuel benefits, provided by third parties changed
on the 6 April 2000.
NIM16035 provides guidance on who is
liable to pay Class 1A NICs on benefits, including car and car fuel
benefits, from 6 April 2000.
For tax years up to and including 1999/2000, where a car
by someone other than the employer, the person liable to pay Class 1A NICs was the person liable to pay secondary Class 1 NICs on that employee or director’s earnings.
Example
A civil servant is seconded to an outside employer but continues to receive their salary from the original employing department. The outside employer provides a car for private use. As the liable secondary contributor, the original employing department is liable for Class 1A NICs on the car provided and not the outside employer who is treated as a third party.
