Let's talk

What can I claim as a legitimate business expense?

According to HMRC, any purchase made wholly and exclusively for your business can be reclaimed as a business expense. This means that any purchase you make which has no other purpose is classed as allowable.

Our guide details all of the expenses you can claim if you’re working through your own limited company.

What if I’m inside IR35?

If your contract is found inside IR35, it can make your case more complicated, but it is still possible to claim tax relief on some expenses.

Common business expenses

Business mileage – If you use your vehicle for business travel, you can claim up to 45p per mile.

Equipment costs – Any tools or equipment you purchase solely for your work can be claimed as an expense.

Business insurance – This includes the cost of protecting your company and could also cover additional expenses such as hiring a solicitor.

Accounting fees – Along with other professional and legal services such as surveyors, your accounting fees form part of allowable contractor expenses.
