One of the most common questions I get from small business owners is: “What can I actually claim as a business expense?” Getting it right can reduce your tax bill — but getting it wrong could raise red flags with HMRC.
Here’s a quick guide 👇
✅ Allowable Business Expenses
Office costs (rent, utilities, stationery, software)
Travel costs (fuel, train tickets, parking – but not commuting to your usual workplace)
Staff costs (salaries, pensions, subcontractors)
Marketing (website, advertising, social media costs)
Training (courses to improve skills related to your business)
🚫 Expenses You Cannot Claim
Personal expenses (holidays, non-business meals, clothing that isn’t protective or uniform)
Client entertainment (meals, hospitality, events – not allowable for tax relief)
Fines or penalties
💡 Tip for Sole Traders: If you work from home, you may be able to claim a proportion of household bills such as electricity, internet, and rent.
The golden rule 👉 An expense must be “wholly and exclusively” for business purposes to be allowable.
✅ Keeping accurate records ensures you don’t miss out on deductions you’re entitled to — and avoids HMRC headaches later.
