# UK Sole Trader Allowable Expenses & Receipt Rules (2026–2027)

**Short answer: UK sole trader allowable expenses are business costs incurred "wholly and exclusively" for trading that you deduct from your turnover on HMRC's SA103 Self Assessment form (or inside your quarterly Making Tax Digital summaries from 6 April 2026) to reduce both your Income Tax and 6% Class 4 National Insurance bill. For 2026/27, you can claim either actual receipted costs or HMRC simplified flat rates (55p/mile for the first 10,000 business miles and £10–£26/month for working from home), and you must keep receipts and records for 5 years after the 31 January filing deadline.**

Every pound of legitimate **UK sole trader allowable expenses** you record saves a Basic Rate taxpayer **26p** (20% Income Tax plus 6% Class 4 NICs) and a Higher Rate taxpayer **42p** (40% Income Tax plus 2% Class 4 NICs). Conversely, losing thermal paper receipts from Screwfix, Toolstation, or petrol stations — or mixing personal spending into your business claim — either costs you tax relief you were entitled to or exposes you to penalties in an HMRC compliance check. This guide sets out the exact [HMRC self-employed allowable expenses rules](https://www.gov.uk/expenses-if-youre-self-employed) for the 2026/27 and 2027/28 tax years, how the SA103 categories map to everyday trade and freelance spending, and what receipts you must keep.

## What is HMRC's "wholly and exclusively" rule for sole traders?

Under Section 34 of the *Income Tax (Trading and Other Income) Act 2005 (ITTOIA 2005)*, an expense is only deductible against your self-employed profits if it is incurred **wholly and exclusively for the purposes of the trade**.

In practice, HMRC applies that test across three buckets:

1. **100% business expenses (fully allowable):** Materials bought for a customer's job, Public Liability insurance, CIS trade tools, safety boots and high-vis workwear, trade body fees (Gas Safe, NICEIC), and accountancy fees.
2. **Mixed-use expenses with a clear, measurable split (business proportion allowable):** A mobile phone contract, home broadband, or a vehicle used 70% for work and 30% privately. You can legally claim the **70% business share**, provided you keep a reasonable calculation or mileage log showing how you arrived at that percentage.
3. **Dual-purpose personal expenses (disallowable):** Everyday jeans and trainers worn on site, ordinary weekday lunches bought while working near home, childcare, and your own personal drawings or National Insurance payments. Because you cannot separate the personal warmth and decency of ordinary street clothes from their work use, HMRC disallows the entire cost.

## Complete 2026/27 HMRC SA103 allowable expenses checklist by category

When you complete your Self Assessment return (Form SA103S or SA103F) or prepare your quarterly Making Tax Digital (`MTD for ITSA`) category totals, your spending maps into these official HMRC boxes:

| HMRC SA103 Expense Category | Allowable Examples for UK Sole Traders & Tradies | Disallowable / Watch-Outs |
|---|---|---|
| **Cost of goods bought for resale or goods used** | Timber, pipe, cable, plaster, fixings, subcontractors, skip hire, plant hire | Materials bought for renovating your own private home |
| **Car, van and travel expenses** | Either **55p/25p per business mile** simplified rate OR business % of fuel, servicing, MOT, road tax, breakdown cover, train/bus fares, hotel stays | Regular commuting to one permanent base; parking fines or speeding tickets |
| **Wages, salaries and other staff costs** | Gross wages, employer NICs, and workplace pension contributions for actual employees | Your own personal drawings or money you take out of the business to live on |
| **Rent, rates, power and insurance** | Workshop/storage unit rent, Public Liability & Professional Indemnity insurance, home-office share or flat rate | Domestic council tax or mortgage capital repayments (unless using actual home-office apportionment rules carefully) |
| **Repairs and maintenance of property and equipment** | Repairing a broken SDS drill, laptop screen repair, sharpening blades, calibration of multifunction testers | Buying a brand-new van or heavy machine (claimed under Capital Allowances / AIA or Cash Basis rules instead) |
| **Phone, fax, stationery and other office costs** | Business share of mobile phone and home broadband, postage, printer ink, invoicing/bookkeeping apps | 100% of a family broadband or mobile contract used heavily for personal streaming |
| **Interest on bank and creditחי charges** | Business credit card interest on trade purchases, merchant card fees (Stripe/Square), business account charges | Repayment of the loan principal itself; personal overdraft fees on a mixed personal bank account |
| **Accountancy, legal and other professional fees** | Accountant fees for preparing your trade accounts, legal fees for chasing a bad trade debt | Fines for breaking the law; HMRC penalties and interest for late Self Assessment filing |
| **Other allowable business expenses** | Branded uniform/PPE (steel-toe boots, hard hats), trade subscriptions, training to update existing trade skills | Training to learn a completely new trade or profession from scratch; client entertainment (hospitable meals/drinks) |

## Should you claim simplified expenses or actual receipted costs in 2026/27?

HMRC's [simplified expenses scheme](https://www.gov.uk/simplified-expenses-if-youre-self-employed) lets sole traders (not limited companies or partnerships with a corporate partner) claim flat rates for vehicles and working from home instead of calculating the business share of every fuel, utility, and insurance receipt.

### 1. Vehicles: 55p/25p per mile vs actual running costs

From **6 April 2026**, the simplified mileage rate for cars and goods vans rose to **55p per business mile on the first 10,000 miles** in the tax year (up from 45p) and **25p per mile above 10,000 miles** (24p for motorcycles). Detailed worked examples are in our [UK self-employed mileage allowance guide](/keel/uk-self-employed-mileage-allowance/).

- **Choose the 55p/25p flat rate** if you drive a reliable car or older van with low repair bills and high business mileage. You only need a contemporaneous mileage log (date, postcode/client destination, purpose, and miles), plus receipts for business parking and tolls (which can be claimed on top).
- **Choose actual vehicle costs + Annual Investment Allowance (AIA)** if you buy a dedicated commercial van (such as a Ford Transit or VW Transporter) where you want to write off the purchase price up to £1 million under AIA (or deduct the purchase under Cash Basis rules for vans) and claim the business percentage of fuel, insurance, servicing, and repairs. Remember: once you claim actual expenses or capital allowances on a specific vehicle, you must stay with that method for as long as you use that vehicle in your business.

### 2. Working from home: £10–£26/month flat rate vs actual share of bills

If you do your quoting, invoicing, or design work from home for **25 hours or more a month**, HMRC's simplified flat rate is:

- **25 to 50 hours a month:** £10 per month (£120/year)
- **51 to 100 hours a month:** £18 per month (£216/year)
- **101 or more hours a month:** £26 per month (£312/year)

Notice that the flat rate covers only household heat, light, and power — it **does not include your telephone or broadband**, so you can still claim the business percentage of your mobile and internet bills on top of the £10–£26 monthly flat rate!

## How do you claim tools, vans, and laptops (Cash Basis vs Capital Allowances)?

Since the 2024/25 tax year, the **Cash Basis** is the default accounting method for UK sole traders unless you actively opt out into traditional accrual accounting.

Under the Cash Basis in 2026/27:

- **Tools, laptops, machinery, and commercial vans** are simply deducted as an ordinary allowable business expense in the tax year you actually pay for them, just like materials — except for **cars**, which cannot be written off upfront as a cash expense and must use either the 55p/25p simplified mileage rate or Writing Down Allowances.
- If you buy a van or expensive diagnostic kit on **hire purchase (HP)** under the Cash Basis, you deduct the deposit and the capital repayments as you pay each monthly instalment, and deduct the interest element in the interest box.

## What receipts must a UK sole trader keep (and for how long)?

Unlike the US IRS $75 travel receipt threshold, **HMRC has no minimum pound threshold below which receipts are not required**. Under Section 12B of the *Taxes Management Act 1970*, you must keep evidence for every business expense you claim.

- **How long to keep UK tax records:** At least **5 years after the 31 January submission deadline** of the relevant tax year. For the **2026/27 tax year** (ending 5 April 2027, filing deadline **31 January 2028**), you must retain your invoices, receipts, and mileage logs until at least **31 January 2033**.
- **Are digital photos of receipts accepted by HMRC?** Yes. HMRC explicitly accepts clear, legible digital photographs or scans of paper receipts showing the front and back (merchant name, date, amount, VAT if applicable, and itemised goods), and once a readable digital copy is safely stored and backed up, you do not have to keep the fading thermal paper slip.
- **Making Tax Digital (`MTD for ITSA`) from 6 April 2026 and 6 April 2027:** If your gross self-employed and property income exceeded **£50,000** in 2024/25, you must keep digital transaction records from **6 April 2026** (or from **6 April 2027** if over **£30,000**). See our [UK sole trader bookkeeping apps with no bank link guide](/keel/uk-sole-trader-bookkeeping-apps-no-bank-link/) for how to keep clean digital records without handing third-party Open Banking aggregators access to your personal current account.

## Frequently asked questions

**Can a UK sole trader claim lunch and food as an allowable expense?**

Ordinary everyday food and drink bought while working at your usual base or within your normal local patch is not an allowable expense because HMRC treats eating as a dual-purpose personal necessity. You can only claim reasonable meal and subsistence costs when you are travelling on a business trip outside your normal working pattern (for example, an overnight stay away from home or an exceptional long-distance site visit for an itinerant trade), and client hospitality or entertaining meals are always 100% disallowable for tax.

**Can I claim work clothes and boots on my UK Self Assessment tax return?**

You can claim the cost of protective clothing and PPE required for site safety (such as steel-toe-cap boots, high-visibility jackets, hard hats, knee pads, gloves, and respirators) as well as clothing that carries a permanent, conspicuous business logo making it a recognisable uniform. You cannot claim ordinary clothing — such as plain jeans, chinos, t-shirts, hoodies, or suits — even if you only ever wear them for work.

**What if I lost a receipt for a UK business expense — can I still claim it?**

If you paid by debit card, credit card, or bank transfer and lost the paper receipt, you can often still claim a genuine business expense if your bank statement shows the merchant, date, and amount and you attach a contemporaneous note explaining exactly what was purchased and which job it was used on (or download a duplicate invoice from your Screwfix, Toolstation, or Amazon Business account). For unrecorded cash purchases with no receipt and no statement line, claim only small, verifiable amounts you logged at the time, as unsubstantiated cash estimates are routinely disallowed in HMRC enquiries.

**Are Class 4 National Insurance or Income Tax payments an allowable business expense?**

No. Your personal Self Assessment Income Tax, Class 4 National Insurance Contributions, and voluntary Class 2 NICs are personal tax liabilities calculated *after* your net business profit has been worked out, so they can never be deducted as a business expense on your SA103 form. Only employer National Insurance Contributions and workplace pension contributions paid for genuine staff you employ on PAYE are deductible business expenses.

**Can I claim pre-trading expenses bought before I officially registered as a sole trader?**

Yes. Under HMRC's pre-trading expenditure rules (ITTOIA 2005 s.57), tools, stock, equipment, domain names, or insurance you bought up to seven years before you officially started trading are treated as if they were incurred on the very first day of trading, provided they would have qualified as allowable expenses had you already been trading. Keep the original receipts or invoices and include them in your first tax year's accounts.
