Tax season can feel overwhelming for small business owners, but understanding the deductions available to you can make a significant difference in your bottom line. After years of working with entrepreneurs and independent professionals, we have identified five deductions that are consistently overlooked.
1. Home Office Deduction
If you use a dedicated space in your home regularly and exclusively for business, you may qualify for the home office deduction. This includes a portion of your rent or mortgage, utilities, insurance, and maintenance costs. The simplified method allows a deduction of five dollars per square foot, up to 300 square feet.
2. Vehicle and Mileage Expenses
Whether you are driving to meet clients, picking up supplies, or traveling between job sites, your business-related mileage is deductible. Keep a detailed log of your trips, the IRS standard mileage rate for 2026 can add up quickly over the course of a year.
The difference between a good tax outcome and a great one often comes down to documentation. Keep records throughout the year, not just in April.
3. Professional Development and Education
Courses, certifications, conferences, and subscriptions related to your field are typically deductible. This includes online learning platforms, industry publications, and professional association memberships.
4. Health Insurance Premiums
Self-employed individuals can often deduct health insurance premiums for themselves, their spouse, and dependents. This is an above-the-line deduction, meaning it reduces your adjusted gross income directly.
5. Retirement Contributions
Contributing to a SEP-IRA, SIMPLE IRA, or Solo 401(k) not only helps secure your future but also reduces your current tax liability. Contribution limits for self-employed individuals are often higher than many realize.
