As a small business owner, understanding the rules around business expenses is vital. These rules determine what counts toward your tax deductions and help you manage your finances better. Many entrepreneurs feel overwhelmed by the complex nature of business expenses. But fear not! This guide will clarify how to identify what you can claim, what you cannot, and why maintaining accurate records is essential.


What Counts as a Business Expense?


The “wholly and exclusively” rule serves as the foundation for determining eligible business expenses. This means an expense must be incurred solely for business purposes. If there is any personal use involved, that portion may not be fully deductible.


Consider a marketing campaign that cost £5,000. If 30% of that budget was spent on personal events rather than business-related advertising, only 70%—or £3,500—would be eligible for deduction.


Documenting your expenses accurately is crucial. Detailed records and receipts serve as evidence to back up your claims if required during an audit. Without proper documentation, you could miss legitimate deductions or face penalties from tax authorities.

Common Allowable Expenses You Can Claim


Knowing which expenses you can claim helps you maximise your deductions. Here are some categories to consider:


Office Costs


This category includes your monthly rent or mortgage allocated to your business space, office supplies such as paper, pens, and even software subscriptions. If you work from home, you may deduct a portion of costs like utilities and internet based on the space used for business.


Travel Expenses


Expenses such as fuel, parking, and public transport related to business activities are generally deductible. For instance, if you used your car to meet a client and spent £50 on gas, that expense would be claimable. Always keep track of your travel expenses by saving receipts and maintaining a log.


Marketing and Advertising


Costs associated with promoting your business, including online ads, print materials, and promotional events, are deductible. If you spent £1,000 on social media ads that resulted in a 25% increase in customer inquiries, that investment qualifies for deduction.


Professional Fees


Fees for accountants, legal advisors, and other insights related to your business can also be claimed. If you paid an accountant £200 for filing your taxes, that is a cost you can deduct, and it might save you more in the long run.


Business Insurance and Utilities


The premiums you pay for business insurance and utility bills essential for operations qualify as deductible expenses. So if your business insurance costs £1,200 each year, you can deduct that from your taxable income.


Equipment, Tools, and Uniforms


Purchasing essential equipment or uniforms for your business can be claimed. For example, if you bought a computer for £800 solely for business tasks, that entire cost may be deductible.


What You Can’t Claim


It's just as crucial to know what you cannot claim. Here are some exclusions:


Personal Costs


Expenses of a personal nature, such as clothing meant for everyday wear, meals with friends, or commuting to work are not deductible. Avoid mixing personal and business finances to prevent complications during tax season.


Client Entertainment


Often, entertaining clients seems like a part of business, but those expenses, whether for meals or events, are typically not deductible. While maintaining good client relationships is essential, these costs do not qualify for tax deductions.


Fines or Penalties


Fines from breaking laws or regulations are not deductible. This includes things like parking tickets or OSHA penalties. Paying fines won’t reduce your taxable income.


Non-Business Travel


Travel costs incurred for personal reasons—even if coinciding with business activities—cannot be claimed. Maintain a clear distinction between business and personal travel.


Grey Areas & Common Mistakes


Mixed-use items can often create confusion. For example, if a mobile phone is used for both personal and business purposes, you must establish how much is for each use.


To clarify, keep a detailed log. If you use your home internet for work 70% of the time and personal use 30%, you could deduct 70% of your internet bill.

Seeking professional tax advice can be invaluable. A skilled accountant or tax advisor can assist you in navigating the complexities of tax law, helping you avoid potential penalties and optimise your deductions.
