Work Uniform & Expense Tax Rebate Calculator

What the Work Uniform and Expense Tax Rebate Calculator does

If you spend your own money on things you need for your job and your employer does not pay you back, you may be owed tax relief, and our uniform tax rebate calculator is built to show you roughly how much. The good news, which surprises a lot of people, is that claiming this money is free. You do not need to pay anyone a percentage of your refund, and HMRC will deal with you directly. This page explains what counts, the real figures for the 2026/27 tax year, and how to put a claim in without overpaying anyone.

Tax relief on employment expenses works by reducing the amount of your income that is taxed. If you are a basic rate taxpayer, every £100 of allowable expense gives you £20 back. A higher rate taxpayer gets £40 on the same £100. It is not a pound-for-pound refund of what you spent, it is a refund of the tax you paid on that part of your earnings. That distinction trips people up, so keep it in mind as you read on.

Who this affects

More employees qualify than realise it. You might have a claim if any of the following apply to you:

• You wear a recognisable uniform or branded workwear and you wash, repair or replace it yourself.
• You are a nurse, healthcare worker, mechanic, electrician, joiner, plumber or other tradesperson with specialist clothing or tools.
• You pay annual fees or subscriptions to a professional body or trade union that is on HMRC's approved list.
• You have to work from home under your employment contract and your employer does not reimburse the extra cost.
• You use your own car, van, motorbike or bicycle for business journeys and your employer pays you less than the approved mileage rate, or nothing at all.

One important caveat up front. If you are self-employed, this relief does not apply to you in the same way, because you deduct expenses against your business profits instead. Have a look at our self-employed tax calculator or the self-employed tax guide for beginners if that is your situation. Everything on this page is aimed at people taxed under PAYE as employees.

How the uniform tax rebate calculator works with 2026/27 figures

HMRC sets standard flat-rate expense amounts for many jobs. These are fixed annual sums you can claim without keeping a single receipt, which is what makes them so easy. The general uniform allowance is £60 a year, but plenty of occupations have higher agreed figures because their clothing and equipment costs more to maintain.

Here are some of the common flat-rate figures for 2026/27:

The figures above are the most widely used amounts, but HMRC's full list is long and detailed by industry and even by employer, so the calculator picks the right one based on what you tell it. Where your trade has its own agreed flat rate, you use that instead of the £60 standard, not on top of it.

Professional fees and subscriptions

If you pay to belong to a professional body that is relevant to your job, and that body appears on HMRC's approved list (known as List 3), you can claim relief on the fee. Think nursing and midwifery registration, engineering institutions, accountancy bodies, the law societies, and many trade unions. You claim the actual amount you paid, so a £300 subscription is worth £60 to a basic rate taxpayer and £120 to someone paying higher rate. You cannot claim a fee your employer already pays for you, and you cannot claim life membership in one lump.

Working from home

If your contract requires you to work from home, or there is genuinely no appropriate office for you to attend, you can claim tax relief on the extra household costs. HMRC's flat rate is £6 a week, which is worth around £62 a year of relief at the basic rate over a full year. You do not need to prove the exact cost when you use the flat rate. The catch most people miss is that choosing to work from home for convenience does not qualify, it has to be a requirement of the job. For a deeper look at the home working rules, our use of home as office calculator and the dedicated work expense tax rebate calculator walk through it, and HMRC sets out the conditions on its working at home page.

Business mileage at AMAP rates

This is often the biggest part of a claim and the one most people overlook. When you drive your own vehicle for work (not your ordinary commute, but genuine business journeys), your employer can pay you tax free up to the Approved Mileage Allowance Payment (AMAP) rates. If they pay you less than the approved rate, or nothing, you can claim tax relief on the shortfall, which is called Mileage Allowance Relief.

You compare the AMAP amount with what your employer actually paid you, and the difference is what you claim relief on. Our mileage allowance calculator handle the 10,000 mile threshold for you, and you can also check your overall position with the tax refund calculator or the cost per mile calculator.

Worked example one: Priya, a hospital nurse

Priya is a band 5 nurse paying tax at the basic rate of 20%. She washes her own uniform, pays £120 a year to keep her Nursing and Midwifery Council registration, and buys her own shoes and tights for shifts. For 2026/27 she can claim the nurses' uniform flat rate of £125, the shoes and tights allowance of £24, and her £120 professional fee. That totals £269 of allowable expenses. At 20%, her relief is around £53.80 for the year. Because she has never claimed before, she can also back-claim the previous four tax years, which lifts her one-off refund to roughly £215 plus the adjustment to her tax code going forward. None of this costs her a penny to claim.

Worked example two: Tom, a higher rate sales rep

Tom earns £58,000 and pays tax at 40% on the top slice of his income. He drove 12,000 business miles last year visiting clients, and his employer reimbursed him at 15p a mile. Using AMAP rates, his approved amount is 10,000 miles at 45p (£4,500) plus 2,000 miles at 25p (£500), giving £5,000. His employer paid him 12,000 miles at 15p, which is £1,800. The shortfall of £3,200 is his allowable expense. At 40%, that is worth £1,280 back to Tom for a single year. Because he is a higher earner, he should also keep an eye on how reliefs interact with thresholds, and the 60% tax trap calculator is worth a look if his income sits near £100,000.

How to claim, and why you should not pay an agent 30%

You can claim in two ways, both free.

• Form P87: if you do not complete a Self Assessment return and your total expenses are £2,500 or less, use HMRC's form P87. You can do it online through your Government Gateway account or on paper. HMRC explains the process on its tax relief for employees guidance, and the form itself is on the P87 publication page.
• Self Assessment: if you already file a tax return, or your expenses exceed £2,500 in a year, you claim through the employment pages of your return. Our Self Assessment tax calculator and the deadlines guide will keep you on track.

Now the part I feel strongly about as an adviser. You will see adverts from refund agents promising to get your money back. Many of them keep 25% to 30% of your refund, sometimes more, plus a fee, and a few have used assignment clauses that funnel future refunds to them too. There is nothing they do that you cannot do yourself in about fifteen minutes. HMRC deals with employees directly and for free. If you have already signed up with one and regret it, contact HMRC, who can tell you what is on file.

Back-claiming up to four years

You are not limited to the current year. You can back-claim for the four previous tax years, so a first-time claim in 2026/27 can reach back to 2022/23. That is why a modest annual allowance can produce a refund several times larger the first time round. Once your claim is processed, HMRC usually adjusts your tax code so you get the relief automatically each year, although it is sensible to check the code is right. Our tax code calculator and the tax codes explained guide help you read it.

Common mistakes people actually make

• Claiming the cost of buying ordinary clothes. A plain suit or smart shoes you could wear outside work does not qualify, even if your boss insists on a dress code. The clothing has to be a uniform or genuinely protective.
• Claiming for things the employer reimbursed. Relief only applies to costs you actually bore yourself. If you were paid back, there is nothing to claim.
• Claiming the £60 uniform rate on top of a trade flat rate. You pick one, not both.
• Forgetting mileage entirely. The reimbursement on your payslip is often well below 45p, and that gap is real money left on the table.
• Working from home by choice. If you simply prefer home, rather than being required to, you cannot claim the home working relief.
• Letting an agent take a cut. Worth repeating, because it is the costliest mistake of all.

How to use this tool

Tell the calculator your occupation or the type of expense, your business mileage and what your employer paid, any professional fees, and whether you work from home under your contract. It applies the right 2026/27 flat rates and AMAP figures, works out the relief at your tax rate, and estimates your back-claim across earlier years. Treat the result as a well-informed estimate to take into your P87 or Self Assessment return, not a formal HMRC calculation.

While you are here, it is often worth understanding your wider tax picture. The income tax calculator, the take-home pay calculator and our overview of UK income tax rates and bands for 2026/27 all help you see how a rebate fits into your overall position. If you suspect you have overpaid more generally, check if HMRC owes you money is a sensible next step.

Next steps

Gather what you spent, run the numbers through the uniform tax rebate calculator, and then claim free using form P87 or your Self Assessment return. If your circumstances are complicated, for example you have multiple employers or large expenses, a short conversation with an accountant can pay for itself. Either way, do not hand a third of your money to a refund agent for a job you can do yourself.
