Employer National Insurance explained (2026/27)

Employer National Insurance is the contribution a business pays on top of an employee's wages — separate from the NI deducted from the employee's own pay. It's one of the biggest "hidden" costs of employing in the UK. Here's how it works in 2026/27.

What it is

Formally it's Secondary Class 1 National Insurance Contributions. When you run payroll, you deduct the employee's own (primary) NI and Income Tax from their pay — and on top, the business owes its own (secondary) NI to HMRC. The employee never sees the employer's contribution; it's a cost you carry.

The 2026/27 numbers

In plain terms: you pay 15% on everything an employee earns above £5,000 a year. There's no upper limit — unlike the employee's own NI, the employer rate doesn't taper off at higher pay.

How to work out what you'll pay

The basic calculation is simple:

Some quick examples for 2026/27:

(These ignore the precise way NI is worked out per pay period, but they're close enough for budgeting.)

The Employment Allowance can wipe it out

Eligible employers can claim the Employment Allowance — for 2026/27, up to £10,500 knocked off your employer NI bill for the year. From April 2025 the old £100,000 NI-bill cap was removed, so far more employers qualify. For a small team, this can reduce your employer NI to zero. It isn't automatic — you have to claim it through your payroll, and a few categories of employer are excluded, so it's worth checking eligibility.

A note for overseas employers

If you're an overseas company employing in the UK — whether through a UK entity or a DPNI scheme — employer NI still applies in the normal way. It's a genuine cost of UK employment, not something the overseas structure removes. The good news is it's entirely predictable, and any allowance you're entitled to can be claimed.
