Top Tax Deductions Every Small Business Owner Should Know

For small business owners, knowing how to maximize tax deductions is a powerful way to improve profitability. A tax deduction lowers taxable income, which directly reduces the amount of tax owed. However, not every expense qualifies, and IRS rules can be tricky.

To be deductible, a business expense must be both ordinary (common in your trade or industry) and necessary (helpful and appropriate for your business). These two standards are what the IRS uses to decide whether an expense can be written off.

Qualifying Business Expenses: What Counts and What Doesn't

Business expenses are deductible only if they are directly related to running your company. Common qualified deductions include rent, utilities, office supplies, employee wages, and professional services. In contrast, personal costs or overly extravagant spending do not qualify.

According to IRS Publication 535, only expenses that are ordinary and necessary can be deducted

For instance, you can deduct office rent, but you cannot deduct your entire home utility bill unless part of your home is a designated office space. Similarly, meals with clients are only partially deductible, while entertainment expenses are generally disallowed. Knowing these rules helps small business owners avoid mistakes and stay compliant at tax time.

Top Tax Deductions Every Small Business Owner Should Know

Knowing which deductions are most beneficial can save your business thousands of dollars annually. Below are some of the top tax deductions that small business owners frequently overlook but should prioritize.

Home Office Deduction

Business owners who use part of their home exclusively and regularly for work may deduct related costs. Eligible expenses include rent, mortgage interest, utilities, insurance, and maintenance. You can choose between the simplified method ($5/sq. ft., max 300 sq. ft.) or the regular method (track actual expenses).

Vehicle & Travel Expenses

Business use of vehicles is deductible through either the standard mileage rate (65.5¢ per mile in 2024) or actual costs (gas, repairs, depreciation). Travel for business—airfare, lodging, and 50% of meals—is also deductible, provided you keep detailed records.

Employee Wages & Contractor Payments

Payments to employees (salaries, bonuses, commissions) and independent contractors are fully deductible. For contractors earning over $600, businesses must issue Form 1099-NEC. Correct worker classification is critical to avoid IRS penalties.

Office Supplies & Technology

Everyday business supplies like paper, pens, and printer ink are deductible. Technology costs—computers, software, internet—also qualify, though large purchases may require depreciation over time. Tracking these costs helps reduce taxable income.

Professional Fees

Payments to professionals such as accountants, attorneys, consultants, and marketing experts are fully deductible. Keeping invoices and contracts ensures your claims are well-documented and IRS-compliant.

Retirement Contributions

Contributions to plans like SEP IRA, SIMPLE IRA, or 401(k) reduce taxable income. These plans not only provide tax benefits but also help attract and retain employees. Limits vary depending on the type of plan.

Business owners have many demands on their limited dollars: giving raises to employees, investing in new equipment, expanding to new locations, spending on marketing, and more. But retirement savings should become part of the budget for all businesses.

Health Insurance & HSAs

Self-employed business owners may deduct health insurance premiums for themselves, spouses, and dependents. Contributions to Health Savings Accounts (HSAs) are also deductible and provide pre-tax funds for qualified medical expenses.

Depreciation & Equipment

Business assets like machinery, furniture, or computers can be deducted through depreciation. Section 179 allows for immediate expensing of certain assets up to IRS limits, helping businesses accelerate tax savings.

Common Mistakes Business Owners Make

Many small business owners unintentionally miss out on deductions or face IRS scrutiny due to common mistakes. One frequent error is failing to separate personal and business expenses, which can lead to disallowed deductions.

Mixing personal and business expenses → leads to disallowed deductions.

•  Poor record-keeping → makes it hard to prove deductions during an IRS audit.

•  Overstating deductions → can trigger penalties and raise audit risk.

•  Misclassifying workers or expenses → may result in back taxes and fines.

•  Waiting until tax season to organize finances → increases errors and missed deductions.
