Sole trader allowable expenses 2026/27: the HMRC list

Every allowable expense reduces your taxable profit. For a basic-rate taxpayer, £100 of expenses saves about £26 in income tax and Class 4 NI. The rule is that a cost must be 'wholly and exclusively' for the business. Here's what that means in practice.

Simplified expenses: flat rates instead of receipts

What you can't claim

Cash basis and equipment

Since 2024/25, the cash basis is the default for sole traders: you record income when it's received and expenses when you pay them. Under the cash basis, most equipment (laptops, tools, machinery) is simply claimed as an expense in the year you buy it, but cars still go through capital allowances. If you opt for traditional accounting, equipment is claimed through capital allowances, usually the Annual Investment Allowance.

The £1,000 trading allowance

If your total self-employed income (turnover) is £1,000 or less in a tax year, you don't need to tell HMRC or file a return for it. If it's more, you can deduct a flat £1,000 instead of your actual expenses. That's better if your real expenses are under £1,000. You can't use both.

Costs before you started trading

Costs from up to 7 years before you started trading can usually be claimed as if you'd paid them on your first day of trading, as long as they'd have been allowable at the time.

Records to keep

Keep receipts, invoices and bank statements for at least 5 years after the 31 January filing deadline for that tax year. Photos of receipts are fine. Log mileage as you go (date, from, to, purpose, miles), because reconstructing a year of journeys in January is painful and less believable if HMRC asks.

Making Tax Digital for Income Tax: from 6 April 2026 it applies if your qualifying income (self-employment plus property) is over £50,000, from April 2027 over £30,000, and from April 2028 over £20,000. It requires digital records and quarterly updates through HMRC-recognised software.

FAQs

Can I claim my phone bill as a sole trader?

Yes, the business share. If roughly half your calls and data are for work, claim 50% of the bill. A separate business phone can be claimed in full.

Can I claim lunch as a business expense?

Normally no. Your everyday lunch is a personal cost. Meals on a business trip away from your usual place of work can be allowable.

How much tax will I pay as a sole trader?

In 2026/27 you pay income tax on profits above your Personal Allowance (£12,570, shared with any salary) and Class 4 NI of 6% between £12,570 and £50,270. Use our self-employed tax calculator for your figure.
