Claiming Business Expenses
As a freelance contractor you will undoubtedly incur business expenses associated with undertaking an assignment at a client site. The good news is that some of these business expenses may be claimed on a tax free basis.If you’re a contractor running a limited company you normally split contract income between salary, expenses and dividends (if outside IR35) as this reduces tax payable on contract income. The level of expenses you take depends on actual expenses incurred but you should consider how proportionate expense claims are to the level of salaried income. Taking a salary of £12k and expenses of £15k may seem artificial to the HMRC which may lead to unwanted attention.
When claiming business expenses you need to ensure that:
- The expense is wholly, exclusively and necessarily incurred in the performance of your duties
- The expense is allowable by the HMRC if caught by IR35
- Site Based Rules are complied with if it is a site-linked expense
Allowable Business Expenses
Business expenses may be claimable before tax is deducted so long as the expense was incurred wholly, exclusively and necessarily in the performance of your duties. It is important to understand that as the Director of your own limited company you are solely responsible for whether or not an expense is claimable.To claim an expense you must be able to show a valid receipt for the claim and ensure that you comply with site based rules. Claimable expenses may include:
- Travel

- Business Telecoms
