The Truth About Self-Employment Tax: What Every Business Owner Should Know

If you're a contractor, entrepreneur, or small business owner, self-employment tax isn't just a line on a form—it’s a major part of managing your finances responsibly. Unlike traditional employees, you’re responsible for both the employer and employee share of Social Security and Medicare. It’s a big deal, but it doesn’t have to be overwhelming.

Let’s break it down and show you how to take control.

What Is Self-Employment Tax?

Self-employment tax covers your Social Security and Medicare contributions. It’s calculated on 92.35% of your net business income. The current rate is:

  • 12.4% for Social Security (up to $168,600 in 2024)

  • 2.9% for Medicare, with no income cap

That means you're paying a total of 15.3% on your self-employment income—essentially both sides of what a W-2 employee would see as payroll taxes.

How Net Earnings Are Calculated

Here’s where being self-employed can work in your favor. Unlike W-2 employees with limited deductions, you can write off a wide range of legitimate business expenses to reduce your taxable income. A few common ones include:

  • Home Office Deduction: If you use a dedicated part of your home for business, you can deduct related expenses—even if your business is 100% virtual.

  • Vehicle Use: If you drive for work, track your business mileage or actual expenses. This is especially valuable for service providers who travel to clients.

  • Professional Services: Fees paid to bookkeepers, accountants, attorneys, or consultants are fully deductible.

  • Continuing Education: Courses, webinars, and conferences that help you build your business skills can be deducted.

Why It’s Different from Being an Employee

Self-employed professionals don’t have taxes withheld from each paycheck, so staying ahead requires a little more planning:

  • Pay Quarterly Estimates: Use IRS Form 1040-ES to avoid penalties and stay in control of your cash flow.

  • Deduct Health Insurance: If you pay for your own health insurance, you may be eligible for a deduction that reduces your taxable income.

  • Choose the Right Business Structure: At a certain point, forming an LLC or electing S Corp status could reduce your tax burden. It's worth exploring as your business grows.

Not All Income Is Treated Equally

Some income sources—like rental income or notary fees—may be exempt from self-employment tax, depending on how they’re earned. But don’t assume. Fluctuating income, industry-specific rules, and evolving IRS guidelines make it essential to keep detailed records and consult a professional when things get complicated.

The Bottom Line

Self-employment tax can feel like a heavy lift, but you don’t have to carry it alone. Staying organized and informed helps you maximize deductions, avoid surprises, and plan with confidence.
