Top 10 Tax Deductions Every Self-Employed Person Should Know

Joseph Segura, CPA·6 min read·

One of the biggest perks of self-employment is the ability to deduct ordinary and necessary business expenses. Unlike W-2 employees, who have very limited deduction options, self-employed individuals can write off a wide range of costs that reduce their taxable income.

Here are the top 10 deductions you should be taking advantage of:

1. Home Office Deduction — If you use part of your home exclusively and regularly for business, you can deduct a portion of your rent or mortgage, utilities, and insurance. The simplified method lets you deduct $5 per square foot, up to 300 square feet.

2. Self-Employment Tax Deduction — You pay both the employee and employer portions of Social Security and Medicare taxes (15.3% total). The good news: you can deduct half of that amount from your gross income.

3. Health Insurance Premiums — If you pay for your own health, dental, or vision insurance, you can deduct 100% of those premiums — even if you don't itemize.

4. Retirement Contributions — Contributing to a SEP-IRA, Solo 401(k), or SIMPLE IRA reduces your taxable income dollar-for-dollar. A SEP-IRA lets you contribute up to 25% of net self-employment income.

5. Vehicle Expenses — If you use your car for business, you can deduct either the actual expenses (gas, insurance, repairs) or use the standard mileage rate (67 cents per mile in 2024). Keep a mileage log!

6. Business Meals — 50% of meals with clients, customers, or business associates are deductible. The meal must have a clear business purpose.

7. Education & Professional Development — Courses, books, seminars, and subscriptions that improve your skills in your current business are fully deductible.

8. Software & Subscriptions — Business software, cloud storage, project management tools, and professional subscriptions are deductible business expenses.

9. Phone & Internet — The business-use percentage of your phone and internet bills is deductible. If you use your phone 60% for business, you can deduct 60% of the cost.

10. Startup Costs — If you launched your business recently, you can deduct up to $5,000 in startup costs in your first year, with the remainder amortized over 15 years.

The key to maximizing these deductions is keeping good records throughout the year. Use a dedicated business bank account, save your receipts, and track your expenses in a spreadsheet or accounting software.
