What Is Employment Allowance and How Does It Work?
Around 1,418,000 UK employers had Employment Allowance offset against their National Insurance bill in the 2025 to 2026 tax year, a 16% rise on the year before, and 85% of them employed nine people or fewer [1]. The relief is worth up to £10,500 a tax year [2], which makes it the largest routinely available National Insurance relief in the UK employer toolkit.
Despite that reach, Employment Allowance is widely misunderstood. It is not a grant, not a payment, and not a general tax credit. It is a deduction applied against one specific liability, employers' secondary Class 1 National Insurance, and it disappears at the end of each tax year whether or not it has been used.
This article explains what the allowance actually is in law, how it moves through a payrun, who qualifies and who is shut out, and the three assumptions that most often lead an employer to claim when it should not, or fail to claim when it could.
Key takeaways
- Employment Allowance is a deduction against employers' secondary Class 1 National Insurance, introduced by the National Insurance Contributions Act 2014 [3].
- It reduces the National Insurance an employer pays HMRC each payrun until the annual amount is exhausted or the tax year ends [2].
- The allowance must be applied before any other deduction that reduces secondary Class 1 liability [4].
- Employers whose work is wholly or mainly of a public nature cannot claim, although registered charities can [5].
- The claim is a single indicator field on an Employer Payment Summary, submitted once per tax year [6].
- An unused balance cannot be carried into another tax year; it is set off against other liabilities or refunded after year end [7].
What Employment Allowance actually is
Employment Allowance is a statutory relief created by section 1 of the National Insurance Contributions Act 2014 and available from 6 April 2014 onwards [3]. The legislation frames it as a qualification test rather than an application: a person qualifies for the allowance in a tax year if they are the secondary contributor in relation to payments of earnings and, as a consequence, incur a secondary Class 1 National Insurance liability [8].
That framing explains two of its more counter-intuitive features. Because qualification depends on incurring a liability, an employer with no secondary Class 1 liability has nothing to qualify for. And because the allowance is a deduction rather than a payment, its value is capped by the liability it is set against rather than by the headline figure.
The liability it reduces, and the ones it does not
Employer National Insurance is charged at 15% on earnings above the Secondary Threshold of £5,000 a year [9]. Employment Allowance reduces that charge and nothing else. The table below sets out what falls inside and outside its scope.
| Liability | Reduced by Employment Allowance |
|---|---|
| Employers' secondary Class 1 National Insurance | Yes |
| Employees' primary Class 1 National Insurance | No |
| Income tax deducted under PAYE | No |
| Class 1A National Insurance on benefits in kind | No |
| Class 1B National Insurance on PAYE Settlement Agreements | No |
| Apprenticeship Levy | No |
| Construction Industry Scheme deductions | No |
The distinction matters because the PAYE bill an employer pays HMRC each month bundles all of these together [10]. An employer watching only the total figure can conclude that the allowance is not working when in fact it is reducing one component of a larger sum. Businesses running payroll through HMRC-recognised payroll software can see the allowance applied as a separate line rather than netted into a single total.
Why the amount changed
The maximum was set at £2,000 when the relief began and has been raised by regulation and by statute several times since. The most recent increase, from £5,000 to £10,500 with effect from April 2025, was made by the National Insurance Contributions (Secondary Class 1 Contributions) Act 2025, the same legislation that raised the employer rate to 15% and cut the Secondary Threshold from £9,100 to £5,000 [11].
The three changes were designed to work together, and the take-up figures show the effect: claimant numbers jumped by roughly 195,000 employers in a single tax year, the largest annual movement since the relief was introduced [1]. Part of that came from the removal of the £100,000 liability cap, which had excluded larger employers from April 2020 onwards [12].
How the allowance moves through a payrun
The mechanics are simpler than the eligibility rules, and understanding them removes most of the confusion about when the benefit appears.
The order of operations
Once HMRC has received a claim, the allowance is set against the secondary Class 1 liability arising on all employees' earnings combined, before the employer pays the PAYE bill [4]. Critically, the allowance must be applied before any other deduction the employer is entitled to make against secondary Class 1 liability, so it takes priority in the calculation stack [4].
The allowance can be consumed in a single pay period or spread across several, depending purely on the size of the liability arising each time [4]. An employer with a monthly employer National Insurance bill of £4,000 exhausts the allowance during the third month of the tax year. An employer with a bill of £700 a month spreads it across the full twelve. Neither is doing anything different; the allowance simply runs out when the liability catches up with it.
What the employer actually sees
The effect appears in the amount paid over to HMRC rather than on any employee's payslip. Employees' own National Insurance, tax and net pay are unaffected, because the relief operates only on the employer's side of the calculation [13]. Full Payment Submissions continue to report the full secondary Class 1 liability arising, and the allowance is applied against the resulting charge [1].
The running total of allowance used is visible in the employer's HMRC online account, which is the most reliable place to confirm that a claim registered correctly [14]. Accountants managing this across a book of client schemes generally reconcile it at the same point each month from a multi-client payroll dashboard rather than logging into each employer's account separately.
Making the claim
The claim itself is one field. The employer sets the Employment Allowance indicator to 'Yes' on an Employer Payment Summary and submits it under Real Time Information [6]. No supporting evidence is filed and no HMRC approval is issued; the employer self-assesses eligibility and carries the responsibility for that assessment.
Employers whose software cannot submit an Employer Payment Summary can claim through HMRC's free Basic PAYE Tools, and the small number of employers exempt from online filing use a paper form RT5, ticking the allowance box on every submission [6]. A claim can be made at any point in the tax year, but claiming early puts the benefit into cash flow sooner [14].
Who qualifies
The qualifying population is broad. Businesses, charities, community amateur sports clubs and individuals employing a care or support worker can all claim, provided they incur a secondary Class 1 liability [12]. The care and support worker route was added by regulation in 2015 and is a deliberate exception to the general exclusion of domestic employment [15].
The public sector test
An employer whose activities are wholly or mainly of a public nature cannot claim. HMRC reads "wholly or mainly" as more than 50% of the employer's work carried out in or for the public sector [5]. The test is not about who pays the invoice but about the character of the function performed.
HMRC's indicators are whether the employer acts on behalf of or in place of government or a public authority, whether it holds or exercises statutory powers, and whether its activities could be subject to judicial review [16]. An employer can assess the proportion by headcount engaged in public-nature duties, by time spent, or by turnover derived from those activities [16]. Registered charities sit outside this test entirely and can claim even where their work is wholly of a public nature [5].
The single-director test
A limited company where the sole director is the only person liable for secondary Class 1 National Insurance cannot claim, a restriction introduced by regulation in 2016 [17]. Take-up data shows the effect clearly: claimant numbers fell by around 120,000 in the tax year after the rule took effect [1].
The restriction applies to limited companies only, so an unincorporated sole trader taking on their first employee is not caught by it [18]. That distinction is one of several reasons why payroll for sole traders and payroll for owner-managed limited companies follow different compliance paths despite looking identical on the surface.
What the allowance is worth to a small employer
The take-up figures make the shape of the beneficiary population clear. Around 1,205,000 of the employers who benefitted in the 2025 to 2026 tax year employed between one and nine people, while fewer than 4,000 had 250 or more staff [1]. The relief is nominally open to employers of any size, but its value is concentrated at the small end because a £10,500 cap is absorbed almost immediately by a large payroll.
Worked position at three payroll sizes
Applying the 15% employer rate to earnings above the £5,000 Secondary Threshold gives the following positions [9].
| Payroll | Secondary Class 1 liability | Allowance used | Proportion of the bill removed |
|---|---|---|---|
| 2 employees on £24,000 | £5,700 | £5,700 | 100% |
| 6 employees on £28,000 | £20,700 | £10,500 | 51% |
| 20 employees on £32,000 | £81,000 | £10,500 | 13% |
The two-employee business in the first row pays no employer National Insurance at all, but leaves £4,800 of allowance unused and cannot recover it [7]. The twenty-employee business uses every pound of the allowance yet still carries £70,500 of employer National Insurance, which is why the relief functions as a small-employer measure in practice even though the eligibility rules no longer say so.
The sectors that claim it
Wholesale and retail trade was the largest claiming sector in the 2025 to 2026 tax year at 227,000 employers, followed by construction at 186,000 and professional, scientific and technical activities at 178,000 [1]. Those three account for 42% of all claimants between them, and all three are characterised by small units with modest wage bills rather than by any sector-specific eligibility rule.
Around 70,000 claimants were households acting as employers, the population covered by the care and support worker route [1]. These employers typically run a single-employee scheme and are among the most likely to overlook the annual re-claim, since they have no finance function and often no agent [22]. Employers at that scale who pay staff only occasionally sometimes work outside a running scheme altogether, using an instant payslip generator for individual payments, in which case there is no Employer Payment Summary for the claim to sit on.
Three assumptions that cause problems
The relief is administratively light, and that lightness is precisely what allows errors to persist unnoticed across several tax years.
The first assumption is that the claim renews itself. It does not. The allowance must be claimed in each tax year, and an employer who changes payroll provider mid-year or migrates to a new platform can lose the indicator in the transfer without any error being raised [19]. Nothing in the Real Time Information response signals a missing claim, because a missing claim is a valid state.
The second is that an unused balance is money owed. It is not. Where the employer's secondary Class 1 liability for the year is below the annual amount, the benefit is capped at the liability actually incurred, and the difference is not refundable [7]. Where a claim is made after the tax year has ended, HMRC checks the National Insurance record and refunds either the full annual amount or the liability actually paid, whichever is lower [4].
The third is that group companies each get an allowance. Where two or more companies are connected at the start of the tax year, only one may claim, and the connection is fixed for the whole year regardless of later restructuring [20]. Platforms embedding UK payroll through an HMRC-recognised payroll API typically model the allowance as a scheme-level attribute with an explicit group flag, precisely so that a multi-entity customer cannot claim twice by accident.
Conclusion
Employment Allowance is best understood as a rebate mechanism embedded in the payrun rather than as a benefit an employer receives. It qualifies automatically in law, is claimed with a single indicator, is consumed silently as liability arises, and expires at the end of the tax year. Every one of those properties makes it easy to operate and equally easy to get wrong, which is why the relief with the highest take-up in the UK employer population is also one of the most frequently misclaimed.
The direction of travel points towards the eligibility judgement mattering more than the arithmetic. Since the £100,000 cap disappeared, the questions that decide whether an employer can claim are structural: whether the business performs functions of a public nature, whether it is connected to another company, whether a sole director is the only person above the Secondary Threshold. None of those is visible in payroll data, and all of them change with corporate events rather than with payruns. The employers most exposed are the ones whose structure has moved since the last time anyone checked, which is an argument for revisiting the test annually rather than treating it as settled at incorporation.
Frequently asked questions
Does Employment Allowance appear on an employee's payslip?
No. The allowance reduces the employer's own National Insurance liability and has no effect on an employee's gross pay, tax, National Insurance or net pay [13]. Payroll continues to report the full secondary Class 1 liability on the Full Payment Submission, and the allowance is applied against the resulting charge before the employer pays HMRC [4].
Can a charity claim Employment Allowance if most of its work is publicly funded?
Yes. The public-nature restriction that blocks other employers does not apply to registered charities, which can claim even where their activities are wholly or mainly of a public nature [5]. Community amateur sports clubs are treated the same way [12]. Charities that are connected to other charities remain subject to the rule allowing only one claim across the connected group.
What happens if an employer claims Employment Allowance when it was not eligible?
The employer becomes liable for the secondary Class 1 National Insurance the allowance was set against, since the deduction was never validly available [19]. HMRC does not approve claims in advance, so an incorrect claim can run for several tax years before it surfaces. The correction route is to set the Employment Allowance indicator to 'No' on the next Employer Payment Summary and settle the resulting liability [21].
Is Employment Allowance available to an employer that only pays staff below the Secondary Threshold?
In practice, no benefit arises. Qualification depends on incurring a secondary Class 1 National Insurance liability, and no liability arises on earnings below the Secondary Threshold of £5,000 a year [9]. The allowance has nothing to be set against, and no refund is available for the unused amount [7]. The position changes as soon as one employee is paid above the threshold.
