Are You Claiming All the Business Expenses You're Entitled To?

23 June 2026

For many business owners, managing day-to-day operations often takes priority over reviewing financial records in detail. However, failing to claim all allowable business expenses could mean you are paying more tax than necessary and reducing your overall profitability.

Most business owners are familiar with common expenses such as office rent, utility bills, wages and business insurance. Yet every year, many businesses miss out on valuable tax relief simply because they are unaware of what they can legitimately claim.

“Claiming the right expenses is not about cutting corners. It is about making sure your business is not paying more tax than it needs to.”

You might be surprised what you can claim for

Many allowable expenses often go unnoticed. Depending on your business and how the cost is used, you may be able to claim for:

Professional subscriptions and memberships relevant to your industry
Working from home costs, including a proportion of heating, electricity and broadband
Business mileage when using your personal vehicle for work-related travel
Mobile phone costs where the contract is used for business purposes
Staff entertainment events, such as annual parties, within HMRC limits
Training courses that help maintain or improve existing professional skills
Business gifts to clients, subject to HMRC rules
Software subscriptions, including accounting packages, CRM systems and productivity tools
Bank charges and business loan interest
Uniforms and branded workwear featuring your company logo
Eye tests and specialist eyewear required for display screen equipment use
Accountancy, legal and consultancy fees

Small expenses can make a big difference.
Individually, these costs may not seem significant. Over a full year, they can add up and help reduce your taxable profits.

The importance of good record keeping

HMRC requires businesses to keep accurate records and evidence for expense claims. Receipts, invoices and digital records should be retained to support your claims and show that the costs relate to your business.

One of the biggest mistakes business owners make is underclaiming because they are unsure what qualifies as an allowable expense. While it is important not to claim personal expenditure incorrectly, it is equally important not to miss legitimate opportunities to reduce your tax bill.

Are you missing out?

Regular reviews of your accounts can help identify expenses that may have been overlooked and ensure you are taking advantage of all available tax reliefs.

“The right advice can help you stay compliant while making sure you are not leaving money on the table.”

Final thought

Understanding what you can and cannot claim is an important part of managing your business finances effectively. With the right systems and advice in place, you can improve efficiency, stay compliant and potentially save money each year.

If you are unsure whether you are claiming everything you are entitled to, now could be the perfect time to review your expenses.
