Employment Allowance explained: is your business claiming it?

What is the Employment Allowance?

The Employment Allowance is a government relief that reduces an eligible employer's Class 1 National Insurance liability. From April 2025 it is worth up to £10,500 per tax year, taken off your employer NIC bill as you run payroll — it is not a grant you apply for separately, but a claim made through your payroll software's Employer Payment Summary (EPS).

Because it comes straight off what you owe HMRC, for smaller employers it can wipe out a substantial share of the employer NI bill — in some cases all of it.

Who is eligible?

Most businesses and charities that pay employer Class 1 National Insurance on employees' wages can claim. The main exclusions to check are:

• Companies where the only employee paid above the secondary threshold is also a director — single-director companies with no other staff usually can't claim.
• Connected companies (under common control) share a single allowance between them — only one company in the group can claim it.
• Certain public-sector employers and businesses doing most of their work in the public sector.

Why do so many businesses miss it?

In our payroll reviews, the same causes come up again and again: the claim box was never ticked in the payroll software; the business switched payroll provider and the claim didn't carry over; nobody re-checked eligibility after rules changed; or a group claimed on the wrong company. The result is the same — money left with HMRC that the business was entitled to keep.

Can you backdate a claim?

Yes. If you were eligible in earlier years and didn't claim, you can normally claim the Employment Allowance for up to four previous tax years. That means a business that has never claimed could be owed a significant refund across several years — one of the first things we check in every free payroll review.

How PayrollSmart makes sure you get 100% of it

We review your claim status, verify eligibility (including the connected companies rules), correct the current year and claim back anything you were owed in prior years. It's part of every payroll we run — alongside RTI submissions, payslips, P60s and pension uploads — so the allowance is never missed again.

How much is the Employment Allowance worth?

Up to £10,500 per tax year from April 2025 (it was £5,000 before that). It reduces your employer Class 1 National Insurance bill directly.

Can I backdate an Employment Allowance claim?

Yes — you can normally claim for up to four previous tax years if you were eligible, which can add up to a substantial refund.

How do I know if my business is eligible?

Most employers who pay Class 1 NICs on staff wages qualify, but single-director companies and connected company groups need checking. A free payroll review will confirm your position.
