UK Employment Allowance: £5,000 Off Your NI Bill That 40% of Employers Miss
UK employers with a Class 1 NI liability under £100,000 in the prior tax year can claim up to £5,000 off their employer NI bill via the Employment Allowance. Must be actively claimed each year in payroll software — it doesn't auto-renew. Around 40% of eligible employers either don't claim or claim late. AskBiz detects unclaimed allowance and alerts immediately.

The Unclaimed Allowance Problem#
Dave runs a small logistics firm in Birmingham. He employs 6 drivers. Combined employer Class 1 NI bill last year: £18,400. He is fully eligible for the Employment Allowance (£5,000). His payroll software (an old desktop package) requires him to tick a box at the start of each tax year to claim it. He forgot to tick it in 2023/24. He paid the full £18,400 instead of £13,400. Lost: £5,000. He cannot reclaim it retrospectively beyond 4 years — but in practice most employers miss it and simply never get the money back.
Employment Allowance: The Rules#
You can claim if: (1) Your employer Class 1 NI liability was under £100,000 in the previous tax year. (2) You are not the sole employee who is also a director. (3) You are not a public body or connected to a public body. (4) You have not already claimed via a connected company. The allowance: reduces your employer NI payment each pay period until £5,000 is used up, or the tax year ends. It does not carry over. Must be re-claimed every April. How to claim: tick "Yes" to Employment Allowance in your payroll software (Xero, Sage, QuickBooks all support this) when starting the new tax year. HMRC is notified automatically via the Full Payment Submission (FPS).
AskBiz Employment Allowance Monitoring#
At the start of each tax year, AskBiz checks whether the Employment Allowance has been activated in your payroll settings. If not: "New tax year started. Employment Allowance (£5,000) not yet claimed. Your NI liability last year was £16,200 — you are eligible. Activate in Xero Payroll > Settings > Employer Details to claim immediately." Eliminates the annual forgotten-checkbox problem that costs UK SMBs millions collectively.
Real Example: London Café Chain#
A café with 14 staff across two sites had an employer NI bill of £28,000 last year. They'd never claimed the Employment Allowance — their bookkeeper assumed it was automatic. AskBiz flagged the unclaimed status in April. They activated it immediately. NI savings that year: £5,000. Also discovered they'd missed it for 3 prior years — filed retrospective claims and recovered £11,800 (3 years × allowance amounts before the increase to £5K). Total recovered via one AskBiz alert: £16,800.
Factoring the Allowance Into Your True Cost of Hiring#
When a small employer weighs up whether they can afford a new hire, the Employment Allowance changes the maths more than most owners realise. A Nottingham graphic design studio with two staff was considering a third hire at £28,000 a year. The owner priced the true cost as salary plus roughly 13.8% employer NI, landing on a number that made the hire feel marginal against the studio's cash flow. What she had not factored in was that the studio's employer NI bill for the year, once the third hire was added, still sat comfortably under the £5,000 Employment Allowance threshold — meaning the business would pay close to zero employer NI on its full payroll for that year, not the roughly £2,400 she had budgeted for NI alone. That gap of £2,400 was the difference between the hire feeling risky and feeling straightforward. The lesson generalises: for any business with fewer than roughly four or five employees on modest salaries, employer NI is very often being offset in full by the allowance, so it should not be treated as a real cash cost when budgeting a new role. The mistake goes the other way too — some owners assume the allowance will always cover a new hire's NI and get caught out mid-year when cumulative NI across a growing team finally exceeds £5,000 and PAYE starts deducting employer NI from that point onward. The practical fix is to run the numbers at the point of hiring, not just at year end: check current year-to-date employer NI liability, see how much allowance headroom remains, and only then decide whether the new hire's NI cost is genuinely zero, partially offset, or full price. AskBiz's payroll module shows this running total against the £5,000 cap every pay run, so an owner deciding whether to make an offer can see the real, current cost of employer NI for that hire in seconds rather than estimating it from a rate card.
Eligibility Edge Cases That Trip Up Small Employers#
Most businesses assume Employment Allowance eligibility is a simple yes or no, but two structural situations catch small employers out repeatedly. The first is "connected companies." If a business owner controls more than one company — say, a couple running both a café and a separate catering company under common ownership — HMRC treats those as connected employers for Employment Allowance purposes, and the £5,000 allowance can only be claimed once across the whole connected group, not once per company. A Leeds couple running a bakery and a wholesale bread-supply business as two separate limited companies discovered this the hard way when their accountant flagged that both companies had been claiming the allowance independently for two tax years — an error that had to be corrected with HMRC, with the excess claimed back through one of the two payroll schemes. The fix going forward was straightforward once understood: nominate one company in the group to claim the full allowance and leave the other unclaimed. The second common trap is the single-director company. A limited company where the only person on payroll is also the sole director cannot claim Employment Allowance at all — this rule exists specifically to stop one-person consultancies claiming a relief intended for employers with a genuine team. The moment that same company takes on even one more employee earning above the secondary threshold, eligibility opens up. A Bristol IT contractor operating through his own limited company assumed he could not claim the allowance at all, right up until he hired a part-time bookkeeper — at which point the company became eligible and had simply never applied. Because these edge cases depend on company structure rather than industry or turnover, they are easy to get wrong and easy to leave unclaimed. AskBiz flags both scenarios automatically when setting up payroll — asking whether the business is connected to any other employer and whether there is more than one person on the payroll — so the eligibility check happens once, correctly, rather than being guessed at by whoever set up PAYE originally.
People also ask
Can I claim Employment Allowance if I'm the only director and employee?
No. If you are the sole employee and also a director, you are not eligible. As soon as you hire one additional eligible employee, you can claim.
Can I backdate an Employment Allowance claim?
Yes, up to 4 tax years. Submit a revised Employer Payment Summary (EPS) for the relevant year. Overpaid NI is refunded or offset against future payments.
Does the Employment Allowance reduce employee NI as well?
No. It only reduces employer (secondary) Class 1 NI contributions. Employee NI is unaffected.
What is the Employment Allowance amount in 2024/25?
£5,000 per tax year. This was increased from £3,000 to £5,000 from April 2022, and remains at £5,000 for 2024/25.
Can connected companies both claim the Employment Allowance?
No. Connected companies (same owner or group) can only claim the allowance once between them. They must nominate which company claims.
