From the base salary of £150,000, the employee pension contribution is deducted before calculating taxable income, resulting in a taxable salary of £147,798. Mandatory government charges then reduce take-home income as follows:
- Income Tax: £52,712.32
- Primary Class 1 National Insurance (employee): £4,966.57
- Employee pension contribution: £2,201.50
Take-home pay is calculated as £150,000-£52,712.32-£4,966.57-£2,201.50 = £87,918.10
Additional mandatory charges arising from employment, paid by the employer to the government are:
- Secondary Class 1 National Insurance (employer): £21,419.78
- Employer pension contribution: £1,320.90
Total mandatory government charges linked to employing the worker are: £52,712.32+£4,966.57+£2,201.50+£21,419.78+£1,320.90 = £82,621.07
For every £1 of take-home pay, the government charges £82,621.07/£87,918.10 = £0.94 in mandatory charges.
Total mandatory government charges equal 48.45% of the employer's total cost of £150,000+£21,419.78+£1,320.90 = £172,740.67 for a role advertised with a salary of £150,000. This represents the real employer cost and the real effective tax rate.
The calculation assumes the minimum pension contribution required by law and treats it as salary sacrifice. Pension contributions are not taxes, but they reduce take-home income because they cannot be accessed until age 55 (rising to 57 in April 2028). On withdrawal, 75% of the pension pot is subject to Income Tax. Because the contribution is compulsory, taxable on receipt, unavailable as current income, included in an individual's estate for Inheritance Tax from April 2027 (IHT at 40% at death), and relatively small compared with other deductions, it is treated here as a deduction from take-home pay for simplicity.
