Expenses if you're self-employed

Printable version

1. Overview

If you鈥檙e self-employed, your business will have various running costs. You can deduct some of these costs to work out your taxable profit as long as they鈥檙e allowable expenses.

For example, if your turnover is 拢40,000 and you claim 拢10,000 in allowable expenses, you鈥檒l only pay tax on the remaining 拢30,000 - known as your taxable profit.

If you聽run your own limited company, you need to follow different rules. You can deduct any business costs from your profits before tax. You must report any item you make personal use of as a聽company benefit.

Allowable expenses do not include money taken from your business to pay for private purchases.

Costs you can claim as allowable expenses

You cannot claim expenses if you use your 拢1,000 tax-free 鈥榯rading allowance鈥�.

If you鈥檙e not sure whether a business cost is an allowable expense contact HM Revenue and Customs (HMRC).

Costs you can claim as capital allowances

If you use traditional accounting, claim capital allowances when you buy:

  • equipment
  • machinery
  • business vehicles, for example cars, vans, lorries, bicycles

You cannot claim capital allowances if you use your 拢1,000 tax-free 鈥榯rading allowance鈥�.

If you use cash basis

If you use cash basis accounting and buy a car for your business, you can claim capital allowances on the cost of the purchase. However, all other items you buy and keep for your business should be claimed as allowable expenses in the normal way.

If you use something for both business and personal reasons

You can only claim allowable expenses for the business costs.

Example

You may be able to claim a proportion of your costs for things like:

You鈥檒l need to find a reasonable method of dividing your costs, for example by the number of rooms you use for business or the amount of time you spend working from home.

Example

You have 4 rooms in your home, one of which you use only as an office.

Your electricity bill for the year is 拢1120. Assuming all the rooms in your home use equal amounts of electricity, you can claim 拢280 as allowable expenses (拢1120 divided by 4).

If you worked only one day a week from home, you could claim 拢40 as allowable expenses (拢280 divided by 7).
