Employment Allowance and HMRC: a claiming guide
HMRC administers Employment Allowance entirely through the PAYE Real Time Information system, with no separate application form, and around 1,418,000 employers claimed the relief in the 2025-26 tax year [1] [7]. The relief is worth up to £10,500 off an employer's secondary Class 1 National Insurance bill, yet HMRC sends no confirmation letter when a claim succeeds, which leaves many employers unsure whether their claim has actually registered [1] [4].
The measure is often searched for as "employer allowance", but HMRC's official name is Employment Allowance, and understanding how HMRC processes it removes most of the uncertainty. The claim is a single field on a routine payroll submission, and once it is set, HMRC applies the relief automatically as each payrun is filed.
This guide walks through the HMRC view of the allowance: the eligibility conditions HMRC checks, how to signal a claim through the Employer Payment Summary, what HMRC does after it receives the claim, how unused allowance is refunded, and how far back a claim can be dated.
Key takeaways
- HMRC runs Employment Allowance through PAYE Real Time Information, so the claim is a payroll action rather than a form or letter.
- The allowance is set by putting Yes in the Employment Allowance indicator field on an Employer Payment Summary sent to HMRC.
- HMRC issues no confirmation of a successful claim, but sends an automated rejection message within five working days if a claim fails.
- A claim must be renewed every tax year, because HMRC does not carry it forward automatically.
- Unused allowance can be set by HMRC against other taxes owed, or refunded after the tax year ends, but never beyond the employer's actual National Insurance liability.
What HMRC means by Employment Allowance
Employment Allowance is a reduction that HMRC applies to an eligible employer's secondary Class 1 National Insurance liability, the National Insurance an employer pays on staff wages [1]. The maximum is £10,500 for the 2026-27 tax year, and an employer keeps claiming against each payrun until the allowance is used up or the tax year ends [1] [9].
HMRC restricts the relief to employer secondary Class 1 National Insurance only. It cannot be set against Class 1A or Class 1B National Insurance, which cover benefits in kind and PAYE Settlement Agreements, so an employer whose National Insurance cost is mostly on benefits sees little from the allowance [6]. The relief is not paid as cash: it reduces what the employer owes HMRC each period, which is why it shows up as a lower PAYE bill rather than a payment into a bank account [1].
Because the whole process runs through Real Time Information, the software an employer uses matters. Payroll software that holds the HMRC Recognised badge submits the Full Payment Submission and Employer Payment Summary correctly and applies the allowance without manual reconfiguration, which is the simplest route to a clean claim. Employers running day-to-day UK payroll software rarely need to touch the calculation, but they do need to confirm the indicator is set.
HMRC applies the allowance against the National Insurance liability as it arises each period, so a business with a steady monthly bill draws the allowance down evenly until it runs out. The worked example below shows how HMRC treats an employer whose monthly employer National Insurance liability is £1,200, using the 2026-27 maximum of £10,500 [6] [9].
| Payroll month | Employer NI liability | Allowance used | Allowance remaining | Paid to HMRC |
|---|---|---|---|---|
| Months 1 to 8 | £1,200 each | £1,200 each | Falls from £10,500 to £900 | £0 |
| Month 9 | £1,200 | £900 | £0 | £300 |
| Months 10 to 12 | £1,200 each | £0 | £0 | £1,200 each |
By month 9 the full £10,500 has been absorbed, and the employer pays the balance of that month plus the remaining months in full [6]. HMRC does not spread the allowance evenly across the year; it is used as early as the liability allows.
How HMRC decides whether a business is eligible
Eligibility is not decided by HMRC in advance; the employer self-assesses against HMRC's published conditions and claims accordingly, and HMRC can challenge a claim later [5]. Getting the eligibility test right at the outset is therefore the employer's responsibility.
The core eligibility conditions HMRC applies
To qualify, a business must be a business or public body that does less than half its work in the public sector, such as work for local councils or NHS services [5]. Charities and community amateur sports clubs can claim, and a domestic employer of a care or support worker qualifies even though other domestic employers do not [5]. Since 6 April 2025, employers paying more than £100,000 in Class 1 National Insurance can also claim, because HMRC removed the previous eligibility cap [5] [7].
Connected businesses are treated as one for this relief. Where companies or charities are connected, HMRC allows only one of them to claim, set against a single nominated PAYE scheme, and any unused balance cannot move between the connected employers [6]. Accountants overseeing several client companies commonly manage this from a multi-client payroll dashboard so a connected group never claims twice.
The single-director rule HMRC enforces
HMRC does not allow a limited company to claim where its only employee paid above the Secondary Threshold is a sole director [5]. The rule extends to companies with several staff if the director is still the only person paid above that threshold [8].
The company becomes eligible under HMRC's additional employee test once a second employee or director is paid above the Secondary Threshold, and eligibility then applies for the whole tax year [8]. HMRC confirms this rule applies only to limited companies, so a self-employed person with staff is never caught by it [8].
Employees HMRC excludes from a claim
Some workers cannot count towards a claim. HMRC excludes anyone whose earnings fall within the IR35 off-payroll working rules, and anyone employed for personal, household or domestic work such as a nanny or gardener, unless that person is a care or support worker [5] [12]. A business that engages deemed employees should confirm which part of the payroll genuinely supports a claim before setting the indicator [12].
How to tell HMRC you are claiming
There is no application to complete. The claim is signalled inside the routine payroll return an employer already sends to HMRC, which is why it is easy to miss and easy to forget to renew [2].
Setting the Employment Allowance indicator
To claim through payroll software, the employer puts Yes in the Employment Allowance indicator field the next time an Employer Payment Summary is sent to HMRC [2]. HMRC then offsets the allowance against the employer National Insurance shown on the Full Payment Submissions that follow [7]. If a payroll product has no Employer Payment Summary facility, HMRC allows the free Basic PAYE Tools to submit the claim while the employer keeps running payroll elsewhere, for any number of employees [6]. Platforms embedding payroll into their own product typically set the indicator programmatically through an HMRC-recognised payroll API, so the claim is never dropped between tax years.
An employer with more than one payroll can only claim against one of them, so HMRC advises nominating the scheme expected to carry at least £10,500 of employer National Insurance liability in the year [6]. The claim cannot be moved to another scheme mid-year; it can only be stopped at the tax year end and re-nominated in the new year before any PAYE payments are made [6].
When to send the claim to HMRC
A claim can be sent at any point in the tax year, but the earlier it reaches HMRC, the sooner the allowance starts reducing the National Insurance bill [3]. Where a claim is made partway through the year, HMRC allows it to cover the employer National Insurance liabilities that arose earlier in the same year, up to the point of the claim [6].
The claim does not roll over. HMRC requires a fresh claim every tax year, so the indicator must be set again at the start of each year even where nothing else about the business has changed [3] [6]. This annual renewal is the single most common reason an eligible employer misses out. An employer can check how much allowance has been used through the HMRC online account [3]. Accountants who want to review the numbers before a client's year-end can book a demo of a platform that flags unclaimed allowance across schemes.
What happens after HMRC receives the claim
The absence of a confirmation letter is deliberate, and it trips up first-time claimants who expect an acknowledgement. Knowing what HMRC does and does not send avoids a needless call to the helpline [4].
No confirmation, but a rejection within five days
An employer can begin using the allowance as soon as the claim is submitted, and HMRC does not send a confirmation letter for a successful claim [4]. If a claim is rejected, HMRC sends an automated message within five working days, so silence after submission generally means the claim has been accepted [4]. This is why reconciling the reduced National Insurance figure against payroll records each month is the practical way to confirm the claim is working, a step handled automatically by most small business payroll systems.
Unused allowance and HMRC refunds
If an employer claims late and does not use the full allowance against employer National Insurance, HMRC can put any unused amount towards other taxes owed, including VAT and Corporation Tax where nothing is outstanding on the PAYE bill, or refund it after the tax year ends [3]. One limit is firm: an employer cannot claim a refund for the difference between total employer National Insurance liability and the full £10,500 [3]. The allowance only ever offsets National Insurance that actually arises, so a business with a small National Insurance bill cannot turn the balance into cash [6].
Where a claim is made after the tax year has ended, HMRC offsets it against outstanding current or future PAYE liabilities, and will repay any unused balance only if no PAYE debt remains [6]. An employer that stops a claim before 5 April loses the allowance already given that year and must repay the National Insurance it covered, so a claim should only be stopped when eligibility genuinely ends [2].
Backdating a claim with HMRC and keeping records
HMRC lets an employer claim for up to four previous tax years, dating back to the 2021-22 year, with a separate Employer Payment Summary for each year claimed [3] [6]. A claim for the 2022-23 tax year, for example, must reach HMRC by 5 April 2027 [6]. Where a business claims for an earlier year and the de minimis state aid rules applied, HMRC sends a letter confirming the allowance counted as de minimis state aid, which the employer should keep in case it applies for other such aid [4] [10].
HMRC requires records supporting a claim to be kept for at least three years after the end of the tax year of the claim, showing why the business was entitled, how much allowance was used, and which liabilities it covered [6]. HMRC charges penalties and interest on late returns, and these can arise if a claim is revoked and the allowance repaid while other PAYE remains unpaid [6]. Clean payroll records are the strongest defence if HMRC later queries a claim.
Conclusion
Dealing with HMRC on Employment Allowance is less about paperwork and more about discipline inside the payroll process. The claim is a single indicator on a routine return, HMRC applies the relief automatically, and the only recurring task is to set the claim again at the start of each tax year and reconcile the reduced National Insurance figure as payroll runs.
The parts that catch employers out are the quiet ones: no confirmation letter, an annual renewal that is easy to forget, and a refund rule that never pays out more than the National Insurance actually owed. As HMRC continues to run more of the payroll relationship through Real Time Information, the employers who benefit most from the allowance will be those whose systems treat the claim as a standing part of each new tax year rather than a one-off task.
Frequently asked questions
Does HMRC confirm an Employment Allowance claim has been accepted?
No. HMRC does not send a confirmation letter for a successful Employment Allowance claim, and an employer can start using the allowance as soon as the claim is submitted [4]. If a claim is rejected, HMRC sends an automated message within five working days, so no message usually means the claim has gone through [4].
How do I claim Employment Allowance from HMRC through payroll?
Put Yes in the Employment Allowance indicator field on an Employer Payment Summary sent to HMRC through your payroll software [2]. HMRC then offsets the allowance against the employer National Insurance reported on your Full Payment Submissions, and the claim must be renewed every tax year [3] [7].
Can HMRC refund unused Employment Allowance?
If an employer does not use the full allowance against employer National Insurance, HMRC can set the unused amount against other taxes owed, including VAT and Corporation Tax, or refund it after the tax year ends [3]. However, an employer cannot claim a refund for the gap between total National Insurance liability and the full £10,500; the allowance only offsets National Insurance that actually arises [3].
How many years can Employment Allowance be backdated with HMRC?
HMRC allows a claim for up to four previous tax years, dating back to the 2021-22 year, using a separate Employer Payment Summary for each year [3] [6]. Records supporting each claim must be kept for at least three years after the end of the relevant tax year [6].
