Does the April 2025 employer NI increase affect employee take-home pay?
The employer NI increase does not affect employee take-home pay. Income tax rates, employee NI rates (8% main, 2% above £50,270), and the personal allowance (£12,570) are unchanged in 2025-26. Employees on £55,000 take home the same amount as in 2024-25.
Does salary sacrifice reduce employer NI on a £55,000 salary?
Salary sacrifice arrangements (pension, cycle-to-work, electric vehicle leasing) reduce the employee's gross pay for employer NI purposes. If an employee on £55,000 sacrifices part of their salary, the employer pays NI only on the reduced gross. At 15% employer NI in 2025-26, every £1,000 sacrificed saves the employer £150/year in NI. Many employers share some of this saving with employees, making salary sacrifice schemes more attractive post-April 2025.
How does the Employment Allowance affect the £55,000 employer NI figure?
If the employer qualifies for the Employment Allowance in 2025-26 (up to £10,500/year for eligible businesses), this reduces their total employer NI bill, but it applies at company level, not per employee. For a single employee on £55,000, the employer NI of £7,500/year still applies as calculated; the Employment Allowance simply offsets the employer's total NI liability across all employees. Employers with secondary Class 1 NI above the threshold and fewer than 250 employees typically qualify.
