Self-employment: What expenses can I claim and how can I claim them?

Running your own business isn’t free. From printing business cards for a new venture to paying for repairs on your old business laptop; expenditure can swiftly mount up.

The self-employed can have these costs reimbursed to them through their business. How expenses are deducted depends on the type of business itself. For example, the expenses of sole traders and limited company contractors differ.


Sole trader- May deduct the costs of any ‘allowable expenses’ from their gross earnings before working out their taxable profit – meaning income tax is not paid on earnings used for expenses.

Limited company- Similarly to sole traders, limited company contractors may only deduct expenses incurred solely for the purpose of business, however, do so from their gross earnings before calculating net profit for Corporation Tax purposes.


Allowable expenses: Costs that are essential to the running of a business.

It’s important to note that if something is used with dual purpose, for both business and personal use, you may only claim for the portion of this that relates to business use.

For a more detailed list of allowable expenses and regulations, see the .


What expenses can I claim when self-employed?

Self-employed workers can claim a range of allowable expenses, including the following:

  • Office costs (i.e. rent of business premises or stationery such as printer ink)
  • Travel
  • Advertising or marketing
  • Financial costs (i.e. interest)
  • Cost of insurance
  • Training


What expenses can I claim if I am self-employed and work from home?

By using a ‘reasonable method’ for dividing cost, self-employed people working from home may be able to claim back part of their expenditure, including the following costs:

  • Heating
  • Electricity
  • Internet usage
  • Council tax, mortgage interest, or rent

Reasonable methods include dividing the cost up by room usage or by the hours spent working.


What cannot be claimed as an expense?

  • Money taken from a business to pay for private purchases cannot be claimed as an expense.
  • Fines or penalties. For example, a parking fine cannot be claimed as an expense as it is not a necessary cost of running a business, even if sustained whilst on business-related travel.
  • Customer gifts or client entertainment.
  • Clothing can only be claimed as an expense in certain circumstances. You may not claim for any clothing that could be used for day-to-day wear outside of your business, this extends to suits. Where clothing can be claimed as an expense is where that clothing relates to safety or is a necessary costume (for example in a children’s entertainment company).

If you come to complete your expenses and are unsure about whether something is deemed ‘allowable’, the .gov website has a Self Assessment helpline you can contact for general enquiries of this nature.


How do you claim?

  • Keep a record, save receipts, maintain this record. Whilst you do not need to send in proof of purchase, you should keep things on hand should HMRC ask
  • Calculate allowable expenses
  • State total allowable expenses during your SATR. You get the choice to give a single figure or a detailed breakdown

What are simplified expenses?

Simplified expenses offer the use of a flat rate instead of requiring calculation of actual business costs. Whilst simplified expenses are an option for sole traders and partnerships (excluding partnerships including a limited company contractor), limited companies are not able to make use of this method of collating expenses.

Flat rates can be used for working from home, certain business vehicle costs, and living on business premises. Any expenses exclusive of this list must be calculated as normal.
