Allowable expenses for the self-employed

HMRC lets sole traders deduct certain "wholly and exclusively" business costs from their turnover before tax is calculated. Common categories you can claim include:

Office costs — stationery, postage, printing.
Travel — train, taxi, parking, business mileage (45p/mile for first 10,000 miles in a car).
Equipment — laptops, cameras, tools (often via the Annual Investment Allowance).
Software / subscriptions — design apps, accounting software, hosting.
Phone & internet — the business-use proportion.
Use of home — a flat-rate simplified expenses amount, or apportioned utility bills.
Professional fees — accountants, legal advice (not personal), insurance.
Marketing — website, advertising, business cards.
Training — courses that update skills you already use in your business.

Personal living costs, entertainment, and fines are not allowable. Keep receipts (digital is fine) for at least 5 years from the 31 January submission deadline for the relevant tax year.

This is general guidance, not tax advice. See gov.uk for the full HMRC list.
