Allowable Expenses for Sole Traders
Published on January 18, 2026
As a sole trader, you can deduct certain business costs from your profit before tax. These are called 'allowable expenses'.
Common Allowable Expenses
- Office costs: Stationery, phone bills, postage.
- Travel costs: Fuel, parking, train or bus fares (for business travel, not commuting).
- Clothing expenses: Uniforms, protective clothing, or costumes for actors/entertainers.
- Staff costs: Salaries, subcontractor costs, agency fees.
- Things you buy to sell: Stock, raw materials.
- Financial costs: Insurance, bank charges, interest on business loans.
- Costs of your business premises: Heating, lighting, business rates.
- Advertising and marketing: Website costs, newspaper ads.
Working from Home
If you work from home, you can claim a proportion of your costs for things like:
- Heating
- Electricity
- Council Tax
- Mortgage interest or rent
- Internet and telephone use
You can either calculate the exact proportion of business use or use simplified expenses (flat rates) if you work 25 hours or more a month from home.
Trading Allowance
Instead of claiming expenses, you can use the £1,000 tax-free 'trading allowance'. If your expenses are less than £1,000, this is usually the better option.
