Business Expenses – What’s allowed and what isn’t

You are self employed or maybe you are a new start up. You know that you can claim some business expenses but which ones are allowed and which ones are not? This article will help you.


What are allowable expenses?

Allowable business expensesare purchased products or services that help keep a business running such as stationery, phone bills, and computers. These expenses are deducted from income when calculating taxable profit so you don’t pay tax on these purchases.

What business expenses can I claim?

There are two different expense categories: revenue expenses and capital expenses.

Revenue expenses tend to be purchases that last for a short period of time, often being used immediately and for general operational matters – these include office supplies, rent, insurance, heating,  and travel.

Capital expenses are expenditure on assets that are likely to be used for a longer period of time such as IT equipment or or office furniture. These qualify for capital expenditure tax relief.

What about expenses incurred before I started my business?

It’s likely that you will need to make some purchases in order to start trading. These are known as pre-trade expenses and they can include privately owned items that are being used for business purposes. The general rule is that you made the purchase within 7 years of starting trading, then they can be claimed for tax relief.

There are 5 fundamental rules to follow when determining if an expense is allowable:

  1. You can only claim for the expenses you incur wholly and exclusively during the everyday running of your business.
  1. You cannot claim for expenses that have a dual business and personal purpose e.g. if you extend a business trip abroad for pleasure, you can only claim for the business days.
  1. Business expenses can be paid through your company’s bank account, or you can reclaim the cost and be reimbursed via your company.
  1. The majority of limited company expenses can be offset against your company’s corporation tax liability – although there are some exceptions such as business entertainment.
  1. You need to maintain an accurate record of running costs to justify your actions if HMRC query your claims. 

The following is an overview of the revenue expenses that you are allowed to claim  tax relief on. If you are usnsure, check with your accountant before spending any money.

  • Wages, salaries and related staff costs including pensions, NICs and agency fees
  • Business Premises costs includinginsurance, rent, rates, power, water, repairs
  • Company cars and vans including insurance, fuel, recovery service membership
  • Travel costs  including hotel accommodation on business trips meals for overnight travel, visas
  • Advertising and marketing
  • Other office running costs including phones, internet, printing, postage
  • Professional fees including accontants, solicitors, architects etc.
  • Banking and other financial charges including finance agreements and credit card fees
Did you know? If your employees use computer screens for a large part of their day, they can claim eye tests as well as health checks as limited company expenses. The cost of prescription glasses or contact lenses can also be claimed as business expenses but only if they’re used strictly for screen-based work as part of their employment.

Which expenses are not allowed as tax relief?

There are some disallowable expenses which do not attract tax relief. In general, these are expenses that are partly a business expense and partly a personal expense. Examples include:

  • Business entertainment
  • Childcare costs
  • Clothes unless it is for a branded uniform
  • Fines and costs from breaking the law such as car parking fines
  • Charitable donations, with the exception of small charities
  • Political donations
