An example of an employee earning above the Freeport and Investment Zone Upper Secondary Threshold

The employer hires an employee on 23 May 2024 who is paid £3,000 per month gross by the employer (£36,000 a year).

At the start of the employment the employer reasonably expects that the employee will spend all of their working time at the employer’s business premises so the employee meets the 60% rule.

In practice the employee never works different working time and location arrangements.

The employee was not employed by the employer or a connected employer in the previous 24 months.

The employee and the employer both meet the rules, and the employer claims the relief.

As the employee’s earnings are more than the Freeport and Investment Zone Upper Secondary Threshold of £2,083 per month, the employer will pay secondary National Insurance contributions on the amounts above the Freeport and Investment Zone Upper Secondary Threshold.

An example of an employee not spending 60% of their working time in the special tax site

The employer hires an employee on 1 October 2022 who is paid £3,000 per month gross by the employer (£36,000 a year).

At the start of the employment the employer reasonably expects that the employee will spend 2 days (40% of their working time) at the employer’s business premises in a special tax site and 3 days (60% of their working time) working from home so the employee does not meet the 60% rule.

The employee was not employed by the employer or a connected employer in the previous 24 months.

The employee does not meet the rules for claiming the relief so the employer cannot claim the relief.

The employer will pay secondary National Insurance contributions as normal without claiming the relief on all earnings above the Secondary Threshold (£758 per month in the 2024 to 2025 tax year).
