What Expenses Can You Claim in the UK
Understanding what expenses you can claim is one of the most important aspects of managing your tax in the UK. Many business owners, freelancers, and landlords either miss allowable expenses or claim incorrectly, leading to higher tax bills or potential issues with HMRC.
This complete guide explains allowable expenses in detail, what you can and cannot claim, and how to maximise your tax efficiency while staying fully compliant.
What are allowable expenses?
Allowable expenses are costs that are “wholly and exclusively” for business purposes. These can be deducted from your income to reduce your taxable profit.
In simple terms:
Income – Expenses = Profit → Tax is calculated on the profit
