This article is the official UK contractor expenses guide from Contractor Advice UK. The advice here applies to UK limited company contractors with regard to what expenses can I claim as a contractor. However, most tips in the article also apply to small and medium business owners. Within this guide, we will look at UK contracting expenses and investigate what are business expenses for contractors. In addition, we will look at a contractor expenses list which includes many different types of company expense. Contractor and small business owner costs and expenses will cover a wide range and many of these have certain rules around what you can claim. We will also investigate what can you expense as a contractor when you run your own business and what are allowable business expenses (UK) for your company.

When you set up your company for the first time or are already running your own company, a common question arises: As a limited company contractor, what expenses can I claim as part of my contractor expenses list and what is justifiable as allowable business expenses (UK)? Therefore, this guide will take an excellent in-depth look into UK contractor allowable expenses (limited company) and what you can claim as your tax-deductible contracting expenses.

Initial thoughts

As a UK contractor, what expenses can I claim (limited company)? First, per HM Revenue & Customs (HMRC) guidelines, tax-deductible expenses (UK limited company) are allowed where:

`The cost incurred is `wholly, exclusively and necessary for your business.’

The above means that a contractor’s expenses will be in line with their company’s business engagements and activities. Furthermore, this also means that the limited company expenses you claim should not include any personal element. In contrast, as part of the items on your contractor expenses list, you may incur a personal element with certain costs such as phone or computer use. However, when such amounts are only minor, HMRC will accept this.

What to consider first

In this guide to expenses, generally, when you are in business as a contractor limited company, you can claim for any costs or limited company expenses you incur for business purposes. However, when you are claiming expenses as a contractor you should also bear in mind the `wholly, exclusively, and necessary’ test mentioned above for these to count as UK contractor allowable expenses (limited company).

When you investigate what can I claim as a business expense, your contractor accountant can guide you what to include on your contractor expenses list. They will advise what sort of costs you can deduct when you are claiming business expenses (UK). You can check this with them if you are unsure or in doubt.

Your contractor limited company expenses along with its income will be shown in your company’s income statement when you prepare the business year-end accounts. You will report the profits on the company tax return and calculate the company’s tax bill on your taxable profits.

The benefits when you claim your allowable business expenses (UK)

As a limited company contractor, when your company pays for expenses, it will do so through the company bank account. However, as a director, you may also pay for some business costs directly via your personal funds, e.g., a bank account, credit card or cash.

It is essential to highlight, in this IT contractor expenses guide, that when you pay for business expenses personally, two benefits arise because of reclaiming these through your company. Such business expense claims for contractors will have the following benefits for you:

  • Your business will receive tax relief on the value of your limited company expenses (UK). When you have a UK company and are a contractor claiming expenses, your business will save Corporation Tax (CT) at a rate of 19% or 25%, depending on whether your company is small or large (see our Corporation Tax guide for details). This CT saving will reduce your company’s annual Corporation Tax bill. If you are self-employed, you will save Income Tax at your highest personal tax rate. Therefore, it is important to claim for all business expenses as you will receive contractor tax deductions for these.
  • Your company can refund the value of these allowable business expenses so that it reimburses you after paying for the costs.

UK contractor expenses guide -processes 

Record your contractor business expenses (UK)

When you incur contractor costs and expenses as part of your daily work, you should record these. Indeed, you should do this on an ongoing basis. Also, you can collect this data as a receipt or invoice and record it in your accounts system. What’s more, if you use an online accounting system such as FreeAgent, you can take photos of the receipts and store these online.

Please read our article that covers tax tips for UK contractors for some handy advice you should know when you have your own business. This article includes our latest guidance for the best tax planning tips and ideas.

Recharge your business expenditure

You incur the `usual’ running costs when you run your own business. As part of your contract work, you may also be able to recharge your expenses to your client. This area can often confuse business owners, especially regarding how to recharge VAT. Our guide on recharging expenses covers this in more detail.

In addition, if you have paid for any of the costs personally when you recharge expenses, please make sure that you claim these back from your own company, as mentioned earlier.

Obtain and keep receipts

As mentioned above, you should obtain and retain receipts or invoices for your contractor costs and allowable business expenses wherever you can. When you buy a product or service, you will receive a receipt from a shop, store, or business. Nowadays, some shops and stores also email you a receipt to save on paper.

When you purchase something online, you might receive this via email, or you can download it from the website where you buy this.

Finally, invoices or receipts should be in your business’s name rather than your personal name. Certainly, this is important as it shows that the product or service cost is for the company.

Duality of purpose 

As a business owner, you need to be aware of any expense with a `duality of purpose.’ As part of this guide to expenses for UK contractors, it is key to note that HMRC use this term where there is both a business and a personal element as part of a cost. Such an expense could include a trip abroad which is part business and part holiday. Therefore, when there is any suspicion from HMRC that the expense may not have occurred if it were not for the personal element, they could disallow it.

What sorts of contractor business expenses (UK) can you claim?

The types of tax-deductible limited company expenses can range across lots of different categories. They will also differ depending on which industry you are in and which service you are providing.

As mentioned earlier, you can pay your contractor costs and allowable business expenses by the company bank account or with your personal funds. You should record any that you pay yourself so the company can reimburse you for these.


It may also be worth you considering registering for VAT. Recently, the VAT Flat Rate Scheme (a sub-scheme of VAT registration) was a more tax advantageous scheme. However, nowadays, the `normal’ VAT scheme is better for most contractors. Under this, you will be able to reclaim the VAT on all of your costs.
