Claiming tax relief on job expenses and professional subscriptions

If you pay for something yourself because your job needs it, and your employer has not reimbursed you, you may be able to claim tax relief on the cost. Relief does not refund what you spent. It reduces the tax you owe on income you have already earned, so a basic rate taxpayer who spends £100 on an eligible item can claim £20 of relief, because that is 20% of the cost¹.

The rules are tighter than most people expect. The expense has to be one your employer would allow, you must have paid it yourself, and you cannot claim if your employer paid you back². Professional body fees count only where membership is necessary for the job and the body is on the HMRC-approved list, and lifetime memberships are excluded¹.

There is also a filing threshold. If your expenses claim is more than £2,500 in a year, HMRC will need you to file a Self Assessment tax return if you do not already file one². Below that, you can usually claim by post on form P87, and some claims can be made online².

What tax relief on job expenses covers

Relief applies to expenses you have to pay for out of your own money because of your job, where your employer has not covered them. The clearest example is a professional subscription you must hold to keep working in your role. The relief is calculated on the amount you paid, at your highest rate of income tax, so the value of the same expense differs from person to person¹.

Some expenses are specifically disregarded when employment income is worked out, which means they do not create a tax charge in the first place. These include qualifying removal expenses, transport provided for a disabled employee, armed forces travel facilities, operational allowances, Council Tax Relief, the Continuity of Education Allowance, accommodation allowances for armed forces members, and workplace car parking expenses⁶.

Salary sacrifice arrangements sit alongside this. Employer-provided pensions including advice, childcare, Cycle to Work and ultra-low emissions cars are exempt from the tax and employer National Insurance advantages that normally apply to salary sacrifice⁷. That is a different mechanism from an expenses claim, but it matters if your employer offers both.

Interest relief exists for a narrower set of borrowing. You can claim relief on interest for loans used to buy equipment or machinery for use in your work for your employer, or by a partnership, unless you have already deducted the interest as a business expense. Relief is only available if capital allowances could be claimed, and only on the business proportion if the item is used partly for employment or partnership business⁸.

Professional fees and subscriptions: when membership counts

Fees and subscriptions to some professional bodies are eligible for tax relief if membership is necessary to do your job¹. Two conditions do the work here. The membership has to be necessary rather than merely useful or expected, and the body has to appear on the HMRC-approved list. A subscription to a body you joined for networking, or one your employer would like you to hold but does not require, does not meet the test.

The exclusions are as important as the inclusions. Lifetime membership subscriptions are not eligible, and neither are fees or subscriptions you have not paid for yourself³. If your employer paid the fee directly, or reimbursed you afterwards, there is nothing to claim².

That single rule removes a large share of hopeful claims. The relief exists for costs that have genuinely fallen on the employee.

Where membership is required, the claim is straightforward: the annual subscription, paid by you, for a body on the approved list, claimed at your rate of tax. Where membership is optional, or the employer settles the invoice, there is no claim. If you are unsure which side of the line a particular subscription falls on, the approved list is the starting point, because a body that is not on it cannot qualify however necessary the membership feels.

How much the relief is worth at 20%, 40% or 45%

The value of the relief follows your marginal rate. The government adds tax relief at your highest rate of income tax: 20% for basic rate, 40% for higher rate and 45% for additional rate⁵. For 2026/2027 the basic rate band runs from £12,571 to £50,270, the higher rate from £50,271 to £125,140, and the additional rate applies above £125,140⁴.

The same principle applies to pension contributions, where the arithmetic is easier to see. A 40% taxpayer contributing £1,000 can claim an extra £200 of tax relief from HMRC⁹. Higher rate taxpayers who pay 40% tax can claim the additional 20% either through their tax return or by contacting their tax office³, and in some cases you may need to claim the extra 20% or 25% relief proactively rather than receiving it automatically¹⁰.

For pension contributions the ceiling is your earnings. Each year you receive tax relief on contributions of up to 100 per cent of your UK earnings, salary and other earned income¹¹, and you can get relief on what you pay in up to 100 per cent of your earnings as long as you are under 75¹². If you earn under £3,600, you can get tax relief on up to £2,880 of your pension contributions¹³.

Expenses over £2,500 need a tax return

The £2,500 threshold is the point at which a claim stops being a simple repayment request and becomes part of the Self Assessment system. You must use a Self Assessment tax return if you are claiming relief over £2,500¹. If you do not currently file a tax return and your expenses claim is more than £2,500, HMRC will need you to file one².

The same threshold appears across the guidance. You are an employee who wants to claim tax relief on expenses of more than £2,500 per year¹⁴. Currently, employees who incur more than £2,500 of allowable expenses not already reimbursed by their employer must submit a return¹⁶.

It is worth being precise about what the threshold measures. It applies to the amount of expenses claimed, not to the tax relief those expenses generate. A claim for £2,600 of expenses crosses the line even though the relief at basic rate would be far less than £2,500.

For comparison, the same £2,500 figure appears in the rental income rules, where you also need to complete a tax return if your rental income is above £2,500 after deducting rental expenses¹⁷. The number recurs in the tax system, but it means different things in different contexts, so it is worth checking which rule you are reading.

How to claim if your expenses are under £2,500

Below the threshold, the route is a repayment claim. You can make a claim for tax relief for employment expenses by post using form P87². Some claims can be made online, and if you already file a Self Assessment tax return you make the claim there instead².

The process in outline:

1. Check the expense is eligible and that you paid it yourself.
2. Gather the evidence: receipts, subscription invoices, and confirmation your employer did not reimburse you.
3. Claim by post on form P87, online where available, or through your Self Assessment return if you file one².
4. Keep the records, because HMRC may check the claim later.

That last point matters more than it looks. HMRC processes repayment claims without investigating them first, and may check the claim in detail later. If HMRC thinks your claim was unjustified, the relief must be returned and interest may be charged².

If you pay Income Tax at a higher rate than 20% on pension contributions, you need to claim the extra tax relief yourself, through HMRC or your Self Assessment tax return¹³. The same self-starting principle applies to expense claims: nobody claims on your behalf unless you ask them to.

Do Scottish taxpayers get relief at different rates?

Scottish income tax rates are different, which affects how much additional pension tax relief higher earners can reclaim¹⁸. The mechanics are set out in the Scottish guidance. If your highest rate of tax is 19% then you will continue to get 20% tax relief automatically¹⁹. Where you have paid tax at 45%, you can claim 25% relief up to the amount of any income you have paid 45% tax on, and where you have paid 48%, you can claim 28% relief up to the amount of any income you have paid 48% tax on¹⁹.

The pattern is that the automatic relief at source does not match the Scottish rate structure, so higher earners in Scotland have to reclaim the difference. The same logic applies to expense relief: the relief follows your marginal rate, and in Scotland that rate is set by the Scottish bands rather than the UK ones.

Does claiming job expenses affect my Personal Allowance?

No. Expense relief and the Personal Allowance are separate things. Your Personal Allowance is the amount of income you can receive before paying Income Tax, set at £12,570 for 2026/2027⁴. You pay Income Tax on income above your Personal Allowance²⁰.

The Personal Allowance can only be used against one job, so HMRC gives it to your main one²¹. That rule matters if you have two jobs, because it explains why your second job is often taxed from the first pound. It does not mean expense relief is limited in the same way. A claim for relief on expenses reduces the tax due on income you have already earned; it does not change the allowance itself.

Income that counts towards your tax position includes money you earn from employment, profits from self-employed work including services sold through websites or apps, some state benefits, most pensions including state pensions, company and personal pensions and retirement annuities, rental income unless you are a live-in landlord under the Rent a Room Scheme limit, benefits from your job, income from a trust, and interest on savings over your savings allowance²⁰. If you come to live, work or study in the UK you have to pay tax on your income, which includes wages, benefits, money you make from working for yourself and money you make from renting out a property²². Income Tax also applies to any profit you earn from an inheritance, for example dividends on shares or rental income from a property²³.

Making Tax Digital and future threshold changes

Making Tax Digital for Income Tax changes how some people report income, and the thresholds are being phased in. From April 2026, landlords and sole traders earning over £50,000 a year before tax and expenses need to comply²⁴. The threshold then steps down: more than £50,000 from April 2026, more than £30,000 from April 2027, and more than £20,000 from April 2028²⁵. The same dates appear in debt advice guidance, with April 2026 for qualifying income over £50,000 and April 2027 for qualifying income over £30,000²⁶.

These thresholds apply to self-employment and property income, not to employment expenses. An employee claiming relief on job expenses is not drawn into Making Tax Digital by that claim. The connection is indirect: if you have both employment and self-employment or property income, the way you report the self-employment or property side may change, and the £2,500 expenses threshold for filing a return sits alongside those rules rather than inside them.

The employment section of an online tax return covers record keeping, how to fill in your return, tax relief for employment expenses, and student loan and postgraduate loan repayments²⁷. That is the part of the return where an expenses claim above the threshold is entered.
