Claiming Tax Relief on Tools as a Tradesperson 2026/27
Employed mechanics, engineers and other tradespeople who buy their own tools can claim tax relief on the cost — but the rules differ sharply from the uniform flat rate, and self-employed tradespeople claim differently again. Here is how it works in 2026/27.
Employed vs self-employed: two different routes to the same relief
The mechanism for claiming tax relief on tools depends entirely on your employment status. An employed tradesperson claims relief against employment income using capital allowance rules for employees, typically via a P87 form or Self Assessment employment pages. A self-employed tradesperson instead deducts the tool cost as a business expense against trading profits, generally using the Annual Investment Allowance, and reports it through the self-employment section of Self Assessment.

Marcus is employed at a garage and is required to supply his own tools. He spends £850 on a socket set, diagnostic scanner accessory and a tool chest during 2026/27, none of which is reimbursed.
| Item | Cost | Relief claimed |
|---|---|---|
| Tool set + chest | £850 | Deducted in full against taxable income (employee capital allowance) |
| Tax relief at 20% (basic rate) | £170 | |
| Tax relief at 40% (higher rate) | £340 |
Because the deduction reduces taxable income rather than being a fixed flat-rate figure, the tax saving scales directly with the actual amount spent (subject to HMRC accepting the claim as necessary for the job).
Worked example: self-employed plumber
Aisha is a self-employed sole trader plumber who buys £1,400 of new equipment during the year.

|---|---|---|
| Equipment | £1,400 | Deducted from trading profits via the Annual Investment Allowance |
| Effect | Reduces profits subject to Income Tax and Class 4 NI |
Because Aisha's equipment cost is deducted directly from her trading profits (rather than as a separate employee allowance), it lowers both her Income Tax bill and her Class 4 National Insurance liability for the year.
Keeping records
Unlike the uniform flat rate, tool claims are generally expected to be supported by receipts, particularly for larger purchases — HMRC can ask for evidence, and without it a claim may be rejected or reduced. It is worth keeping a simple running log of tool purchases with dates and costs throughout the year rather than trying to reconstruct it at tax return time.
Frequently asked questions
Can an employed mechanic claim tax relief on their own tools?
Yes, if you are employed (for example, as a garage mechanic) and your employer requires you to provide your own tools without reimbursing you, you can claim tax relief on the cost. Because tools are typically capital items (they last more than one year), the relief is usually given as a capital allowance rather than a simple flat-rate deduction, though HMRC has historically accepted a negotiated flat-rate 'tool allowance' for some trades where record-keeping would be onerous.
Is a tool allowance the same as the uniform flat rate?
No — they are different reliefs. The uniform flat rate (typically £60/year, higher for some trades) covers laundering and replacing recognisable work clothing. Tool allowances relate to the actual capital cost of purchasing tools and equipment, and for many trades HMRC agrees a specific negotiated flat rate through trade unions or employer bodies rather than the generic uniform figure — check the HMRC Employment Income Manual list for your specific trade rather than assuming the £60 uniform rate applies.
How do capital allowances work for an employee's tools?
An employee (rather than a self-employed person) claims relief on tools under the 'capital allowances for employees' rules, which broadly mirror the Annual Investment Allowance available to businesses — the full cost of qualifying tools can typically be deducted from taxable income in the year of purchase, rather than spread over several years, provided the tools are necessary for the job and not reimbursed by the employer.
Does a self-employed tradesperson claim tools differently?
Yes. A self-employed sole trader deducts the cost of tools as a business expense against trading profits, generally using the Annual Investment Allowance for equipment (covering the full cost of qualifying tools and equipment up to the AIA limit in the year of purchase) rather than the employee capital allowance route, and reports this through the self-employment pages of Self Assessment.
What tools qualify for relief?
Tools and equipment that are necessary to do your job and that you personally paid for without reimbursement generally qualify — hand tools, power tools, specialist diagnostic equipment for a mechanic, or a tool chest to store and transport them. Tools your employer provides, lends, or reimburses do not qualify, since you have not borne the cost yourself.
How do I claim if I am employed and not on Self Assessment?
You claim via form P87, either online through your HMRC Personal Tax Account or by post, providing details of the tools purchased and their cost. For claims above certain thresholds HMRC may ask for receipts, so keeping proof of purchase for tool-related claims is worth doing even though the uniform flat rate does not require it.
Can I claim for tool insurance or a tool theft policy?
Generally, insurance premiums for tools you use for work, including cover against theft or damage while you are working, can also be claimed as an allowable expense alongside the cost of the tools themselves, provided the policy specifically covers work tools and you have paid for it personally.
How far back can I backdate a tools tax claim?
As with most employment expense claims, you can typically backdate a tools claim for up to four tax years in addition to the current year, so a claim made in 2026/27 could in principle also cover 2022/23 through 2025/26 if you incurred qualifying, unreimbursed tool costs in those years and did not previously claim.
