How this is calculated

Employers pay Class 1 secondary National Insurance on their employees' earnings — a cost on top of the gross salary, separate from the employee's own NI. For 2026/27 it is 15% on every pound of salary above the secondary threshold of £5,000.00 a year. Below that threshold there is no employer's NI to pay.

So the calculation is simply: (salary − £5,000.00) × 15%. For a director drawing a salary through their own company, this is a deductible business cost — see our take-home calculator for the full picture.

Assumptions

  • Annual-basis figures (real payroll assesses NI per pay period). Good for planning; your payroll software is the payment record.
  • No Employment Allowance is applied — a sole director-employee company can't claim it, and eligibility varies for others.
  • No relief for under-21s, apprentices, veterans or freeport/investment-zone workers, which use different secondary thresholds.

Rates used (2026/27)

  • Employer's (secondary) NIC: 15% above £5,000.00.
