Business expenses you can claim


When you set up your company for the first time or are already running your own company, a common question that arises is what is justifiable as allowable business expenses?

First of all, per HM Revenue & Customs (HMRC) guidelines, a business expense is allowable where:

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

What’s more, this means that you will incur the cost directly in line with your company’s business engagements. The above also means that this should not include any personal element. In contrast, with certain expenses such as phone or computer use, you may incur a personal element. As a result, when such amounts are only minor, HMRC will accept this.

Your contractor accountant can guide you with regards to what you are able to claim. If you are ever unsure you can check this with them.

Benefits of claiming for your allowable business expenses

There are also two benefits to reclaiming expenses that you pay for out of your own pocket:

  1. Your company saves tax at 19% on these against its annual Corporation Tax bill
  2. Your company can refund these to you so that you are reimbursed after paying for these


Recording your allowable business expenses 

When you incur business expenses as part of your daily work, you should record these. Key to note, you will need to do this on an ongoing basis. Also, you can collect this data in the form of 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.

Recharging your business expenses

When you run your own business, you will incur the `usual’ running costs. As part of your contract work, you may also be able to recharge your expenses to your client. Please note, this is one area that can often confuse business owners. Therefore, when you recharge expenses, please note you need to make sure that you claim these back as allowable business expenses from your own company.

Keep receipts for your allowable business expenses

As mentioned above, you should obtain and retain receipts or invoices for business expenses wherever you can. You can obtain this when you buy a product or service from a shop, store, or business. When you buy 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’ name rather than in your name.

What else to consider in terms of allowable business expenses

Duality of purpose 

As a business owner, you need to be aware of any expense that has a `duality of purpose.’ HMRC use this term where there is both a business and a personal element to a cost. Such an expense could include a trip abroad which is part business and part holiday. 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 business expenses can you claim 

The types of allowable business expenses can range across lots of different categories. They can also be paid by either the company bank account or your personal funds e.g. personal bank account, personal credit card or personal cash. The important thing is to ensure sure that you claim for all of them! Therefore, I have drawn up a detailed list below.


It may also be worth you considering registering for VAT. In recent times, the VAT Flat Ratescheme (this is a sub-scheme of VAT registration) was more tax advantageous however, now, the `normal’ VAT scheme is better for most contractors. Under this, you will be able to reclaim the VAT on your costs.

The types / category of allowable business expenses

Travel expenses 

Your company will incur business expenses of a travelling type nature when you visit your main worksite or different client sites. You may also incur these when you travel to other locations for business reasons. Such costs could include when you go to interviews or perhaps when you visit the bank or accountant. Also, this could be when you attend training courses and seminars or make trips to buy company supplies. The types of costs that you may incur will include:

  • Business travel and the costs for overnights stays. These costs can include hotels or B&B’s. It may even include a temporary rented house or flat and the various house running costs such as gas, electric, etc. ***

  • Personal Incidental Expenses Expenses when you are staying away from home overnight for work reasons. These are also known as PIEs. The rate that you can claim is £5 per night in the UK
    and £10 per night outside the UK. This rate is set by HMRC at a level to cover sundry type costs. These will include phone calls home, coffees, laundry, newspapers, etc. ***

Motor vehicle / bike expenses 

If you use your personal car or motor vehicle for business reasons, you will incur allowable business expenses in relation to this. Your business can claim:

  • Mileage allowances for business journeys in your private car. HMRC sets the rates that you can claim, and these are 45 pence per mile for the first 10,000 business miles travelled in a tax year and 25 pence per mile for each mile after that. 
  • You can claim for mileage for travel in your private motorbike or bicycle. The rates that you can claim are 24 pence per mile for a motorbike and 20 pence per mile for a bicycle *** 
  • Motoring expenses using fixed-rate allowances (e.g., claim for the distance travelled)

*** Please note travelling and motor expenses are subject to the `two-year rule.’ 

Salary expenses 

Salaries are also allowable expenses and your company may pay salaries and costs related to this. These may include:

Telephone and broadband charges 

As part of your business, you are likely to incur phone and broadband costs. These costs will consist of:

  • Business calls on your home phone 
  • Mobile phone costs related to business use 
  • Broadband charges for business internet use 

Office expenses 

 Your company may incur office type costs as business expenses. These may include:

  • Postages and stationery, business cards 
  • Printing costs 
  • Use of home as office. Under HMRC’s present allowed rates, you can claim for £4 per week. You may be able to claim for more than this in some cases. If you claim for more, you need to show that your extra household expenses cost more per week as a result of running your business from home.

Computer expenses 

If you have a company computer, you may incur costs with the use of this. 

These costs may comprise of:

  • An annual eye test and the cost of basic glasses, if you require these when you are at work

Other allowable business expenses 

There may be many other types of costs that your company incurs and are genuine business expenses. These might consist of:

  • Entertaining costs -these can be for the entertaining of past, present, or potential future clients. These costs are not tax-deductible. Certainly, though, it is better if your business pays for these rather than you pay for them yourself.
  • Bank charges and interest that you incur on the business bank account. 
  • The annual £13 fee that you pay to Companies House when your business files the Confirmation Statement each year. Any other Companies House fees that you incur when you make specific changes. Most changes do not incur a fee, but a few do, such as when you change the company name and one or two others. 
  • Trivial Benefits -these cannot be more than £50 each time. Please note only directors and employees of `close companies’ can claim these. The amount that you can claim is £300 per year for each director and employee. 
  • Business clothing -you are only allowed to claim here if the clothing is part of a uniform or is protective clothing for your work

Final thoughts 

The list above includes most types of allowable business expenses that you may come across.

However, there may be some that I have missed. Depending on your type of business, there may be other types of expenses that you can claim.

As mentioned, you should take note of any expenses that you incur when you run your own business.  You should also obtain an invoice or receipt each time you commit a cost for your business. Your contractor accountant can guide you if you are ever unsure.

As a final note, I have written many articles on most of the expenses that are listed above. Please have a look at these for more detailed reads on what you can actually claim. My articles also cover any rules that you need to be aware of as a contractor or small business owner.
