What can I actually claim? Expenses for the self-employed
Claiming your business costs properly is one of the simplest ways to lower your tax bill — you only pay tax on your profit, not everything that comes in. Here's what counts, and what doesn't.
The golden rule HMRC uses is that a cost must be "wholly and exclusively" for your business. If something is partly personal, you can usually only claim the business share of it.
Costs you can usually claim
- Stock and materials you buy to sell or use in your work.
- Travel for work — either your actual costs, or HMRC's flat mileage rate of 55p per mile for the first 10,000 business miles in a car and 25p after that. That first-10,000 rate rose from 45p to 55p on 6 April 2026. (Normal commuting to a regular workplace doesn't count.)
- Working from home — a share of your bills, or HMRC's simplified flat rate of £10, £18 or £26 a month depending on how many hours you work from home.
- Phone, internet and software used for the business.
- Tools and equipment, work clothing like uniforms or safety gear, and business insurance.
- Accountancy and other professional fees — yes, our fee is itself an allowable expense.
Costs you can't claim
- Anything purely personal, or the personal share of a mixed cost.
- Everyday clothing (even if you only wear it for work).
- Entertaining clients.
- Fines and penalties, such as parking or speeding tickets.
- The cost of getting to and from a regular place of work.
The easy way to get it right
The biggest wins come from claiming everything you're entitled to without straying into what you're not — which is exactly where a real person checking your figures pays for itself. Keep your receipts (a photo is fine), and we'll sort the rest.
