7 Tax Deductions Small Business Owners Often Miss
You work hard for your money. Make sure you're not giving more of it to the IRS than you have to.
Every year, small business owners overpay on taxes simply because they don't know what they can deduct. The tax code is complex, and unless you're actively looking for these deductions, they're easy to miss. Here are seven of the most commonly overlooked ones.
Home Office Deduction
If you use a dedicated space in your home regularly and exclusively for business, you can deduct a portion of your rent or mortgage, utilities, insurance, and maintenance. The simplified method lets you deduct $5 per square foot (up to 300 sq ft, or $1,500). The regular method calculates the actual percentage of your home used for business. Many business owners skip this because they think it triggers audits — but as long as you qualify, it's a legitimate deduction.
Vehicle and Mileage Expenses
If you drive for business — client meetings, bank runs, supply pickups — you can deduct either actual vehicle expenses or use the standard mileage rate (67 cents per mile for 2024). The key is tracking. Use an app like MileIQ or keep a simple log. Without documentation, you can't claim it. We see business owners leave thousands on the table every year because they don't track mileage.
Professional Development and Education
Courses, certifications, conferences, books, and subscriptions that improve your skills in your current business are deductible. This includes online courses, industry conferences (including travel), professional memberships (like AIPB or NACPB), and even business coaching programs. If it makes you better at what you do, it likely qualifies.
Health Insurance Premiums (Self-Employed)
If you're self-employed and pay for your own health insurance, you can deduct 100% of your premiums for yourself, your spouse, and your dependents. This is an "above the line" deduction, meaning it reduces your adjusted gross income — not just your taxable income. It's one of the most valuable deductions for self-employed business owners.
Retirement Contributions
Contributing to a SEP IRA, SIMPLE IRA, or Solo 401(k) reduces your taxable income while building your retirement savings. A SEP IRA lets you contribute up to 25% of your net self-employment income (up to $69,000 for 2024). A Solo 401(k) can allow even higher contributions if you're the only employee. This is a powerful way to reduce your tax bill AND invest in your future.
Business Software and Subscriptions
QuickBooks, Zoom, Canva, your email marketing platform, project management tools, cloud storage — all deductible. Even your business phone plan and internet service (the business-use portion) count. These small monthly charges add up to significant deductions over a year. Keep a list of all your business subscriptions and make sure they're categorized correctly in your books.
Startup Costs
If you started your business recently, you can deduct up to $5,000 in startup costs in your first year (with the remainder amortized over 15 years). This includes market research, advertising before launch, travel to scope out business locations, consultant fees, and training. Many new business owners don't realize these pre-launch expenses are deductible.
