Allowable Expenses for Self-Employed UK 2026: Complete List of What You Can Claim

If you're self-employed in the UK, every legitimate expense you claim reduces your taxable profit — and therefore your tax bill. Yet thousands of freelancers and sole traders either overclaim (risking HMRC penalties) or underclaim (paying more tax than they need to).

This guide covers every allowable expense category for the 2025/26 tax year, with practical examples and the HMRC rules behind each one.


How Allowable Expenses Work

When you're self-employed, you pay tax on your profit — not your total income. Profit = income minus allowable expenses.

Example: You earn £40,000 and have £8,000 in allowable expenses. You pay tax on £32,000, not £40,000. At the basic rate, that saves you roughly £1,600 in income tax alone, plus National Insurance savings on top.

The golden rule: an expense must be wholly and exclusively for business purposes. If something is partly personal, you can usually only claim the business portion.


Office and Workspace Costs

Working from Home

If you work from home (as most freelancers do), you can claim a proportion of your household costs:

Simplified method — claim a flat rate based on hours worked from home per month:

Actual costs method — calculate the business proportion of your rent/mortgage interest, council tax, electricity, gas, water, broadband, and insurance. If your home office is one room out of five, you can typically claim 20% of these costs.

Which is better? For most freelancers working full-time from home, the actual costs method claims significantly more. But you need records.

Rented Office or Coworking

If you rent a dedicated workspace, coworking membership, or hot desk — 100% claimable as long as it's used for business.

Office Equipment and Furniture


Technology and Software

Tip: If you buy a laptop for £900 and use it 80% for business, claim £720.


Travel

Business Travel (Not Commuting)

Not claimable: Your regular commute to a permanent workplace. If you work from home and travel to a client site, that IS claimable.

Vehicle Costs

Option 1 — Simplified mileage: 45p/mile (first 10,000), 25p/mile (thereafter). Keep a mileage log.

Option 2 — Actual costs: Fuel, insurance, road tax, MOT, servicing, breakdown cover — claim the business proportion. More paperwork but sometimes more valuable for high-mileage drivers.

You must pick one method and stick with it for the life of the vehicle.


Marketing and Advertising


Professional Services


Financial Costs


Training and Development

Not claimable: Training to acquire entirely new skills unrelated to your existing business. If you're a web designer, a photography course isn't allowable — unless you're expanding your web design services to include photography.


Stock, Materials, and Raw Goods


Clothing

Very limited. You can claim:

Not claimable: Smart clothes for meetings, even if you only wear them for work. HMRC's test is whether the clothing is "wholly and exclusively" for business — a suit fails this test because you could wear it elsewhere.


Staff Costs

If you hire anyone:


What You CANNOT Claim


Record-Keeping Requirements

With Making Tax Digital rolling out from April 2026, keeping proper records is no longer optional:

Our MTD compliance tools can help you stay on top of quarterly reporting.


How to Maximise Your Deductions

  1. Track everything from day one. The expenses you forget to claim are pure lost money.
  2. Use the actual costs method for home office if you work from home full-time — it almost always beats the flat rate.
  3. Keep a mileage log if you drive for business. Apps like MileIQ automate this.
  4. Claim capital allowances on big purchases (equipment over £1,000).
  5. Don't forget the small things — bank charges, phone bill proportion, cloud storage subscriptions. They add up.

Getting Help

If you're unsure about a specific expense, check HMRC's guidance on allowable expenses or speak to an accountant. The cost of an accountant is itself an allowable expense — and a good one typically saves you far more than their fee.
