Top 10 Tax Deductions Every Self-Employed Person Should Know in 2025

If you're self-employed — a freelancer, contractor, rideshare driver, or small business owner — you're responsible for your own taxes. But the upside is that you have access to dozens of deductions that W-2 employees don't. The problem is most people miss them.

Here are the 10 most valuable deductions for the self-employed, with plain-English explanations of how each one works.

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 internet. There are two methods:

• Simplified method: $5 per square foot of your office space, up to 300 sq ft = max $1,500 deduction.
• Regular method: Calculate the percentage of your home used for business and apply that percentage to your actual home expenses. More math, but often a bigger deduction.

The IRS is strict about "exclusive use" — your home office can't double as a guest room.

2. Self-Employment Tax Deduction

When you're self-employed, you pay both the employer and employee portions of Social Security and Medicare — 15.3% total. The good news: you can deduct half of that self-employment tax from your income. This deduction reduces your adjusted gross income (AGI), not just your business income.

3. Health Insurance Premiums

If you pay for your own health, dental, or vision insurance — and you're not eligible for coverage through a spouse's employer plan — you can deduct 100% of those premiums from your income. This is one of the most overlooked deductions for self-employed individuals.

4. Retirement Contributions

Contributing to a SEP-IRA, SIMPLE IRA, or Solo 401(k) isn't just good for your future — it reduces your taxable income today. With a SEP-IRA, you can contribute up to 25% of your net self-employment income, or up to $69,000 in 2025, whichever is less.

5. Vehicle and Mileage

If you drive for work — visiting clients, making deliveries, or heading to job sites — you can deduct those miles. For 2025, the IRS standard mileage rate is 67 cents per mile. Keep a mileage log with dates, destinations, and business purpose for every trip.

6. Phone and Internet

The percentage of your phone and internet bill used for business is deductible. If you use your phone 70% for work, you can deduct 70% of the bill. Most self-employed people underestimate this one.

7. Business Meals

You can deduct 50% of the cost of meals with clients, customers, or business partners — as long as there's a legitimate business discussion. Keep receipts and note who you met with and what was discussed.

8. Software, Tools, and Subscriptions

Every tool you pay for to run your business is deductible: accounting software, design tools, project management apps, cloud storage, professional subscriptions. If it's essential to your work, write it off.

9. Continuing Education and Training

Courses, certifications, books, webinars, and workshops that improve skills related to your current business are deductible. Note: education to qualify for a new career is NOT deductible, only education that maintains or improves your current work skills.

10. Qualified Business Income (QBI) Deduction

This one is less known but worth hundreds or thousands of dollars. Under the Tax Cuts and Jobs Act, many self-employed individuals can deduct up to 20% of their qualified business income. Income limits and restrictions apply — consult a tax professional to see if you qualify.
