NIM18080 - Class 1B NICs : Liability : Calculation : Example

Smith and Jones Ltd. has a workforce of 1,000 employees. All are chargeable to tax during the tax year 2003/04 on benefits valued at £50 per head.

800 employees pay tax at the basic rate and 200 pay at the higher rate.

The value of items covered by the PSA which give rise to a Class 1 and Class 1A liability is £50,000.

The tax and Class 1B NICs payable under a PSA for 2003/04 and covering the whole workforce would be calculated as follows:

Value of benefits provided to basic rate employees (800 x £50)= £40,000
Tax due @ 22% on £40,000= £8,800
Gross up tax £8,800 x 100/100 – 22= £11,282.05
Value of benefits provided to higher rate employees (200 x£50)= £10,000
Tax due @ 40% on £10,000= £4,000
Gross up tax £4,000 x 100/100 – 40= £6,666.67
Total Tax Due= £17,948.72
Value of items liable for NICs= £50,000
Class 1B NICs Due (£17,948.72 + £50,000) x 12.8%= £8,697.44
