What is self-employment tax?

Self-employment tax covers Social Security (12.4%) and Medicare (2.9%) taxes. Employees split this with their employer, but self-employed individuals pay both halves, totaling 15.3% on net earnings.

Why do I pay more tax as self-employed?

You pay both the employee and employer portions of FICA taxes. However, you can deduct half of SE tax from your income, and business expenses reduce your taxable income significantly.

When are quarterly payments due?

Estimated taxes are due April 15, June 15, September 15, and January 15. Missing payments may result in penalties. Use Form 1040-ES to make payments.

What expenses can I deduct?

Common deductions include home office, vehicle expenses, equipment, software, professional services, health insurance premiums, retirement contributions, and business travel. Keep detailed records!

Do I need to pay SE tax on all my income?

SE tax applies to net earnings of $400 or more. Only earned income from self-employment is subject to SE tax - not passive income like investments or rental income.

Expert Tips

You Pay Both Halves: Unlike employees who split payroll taxes with employers, you pay the full amount yourself. This is often a surprise for new freelancers—budget accordingly.
Pay Quarterly to Avoid Penalties: The IRS expects you to pay taxes throughout the year, not just at filing time. Set aside money from each payment and make quarterly estimated payments.
Track Every Business Expense: Home office, equipment, software, travel, professional services—these deductions reduce your taxable income. Keep good records throughout the year.
Retirement Accounts Are Powerful: SEP-IRAs and Solo 401(k)s let you shelter significant income from taxes while building retirement savings. The tax savings can be substantial.
Consider Professional Help: Self-employment taxes get complicated quickly. A good accountant often pays for themselves in tax savings and peace of mind.

Essential Fundamentals — Understanding SE tax

How SE Tax Works

The Double Portion: Employees split payroll taxes with their employer. Self-employed people pay both portions, which is why the rate feels higher than you might expect.
Some Relief Available: The IRS provides adjustments that lower your effective rate. You also get to deduct half of your SE tax from your income tax calculation.
Separate from Income Tax: Self-employment tax is in addition to regular income tax. Many freelancers are surprised by this when they file their first return.

Staying On Top of Payments

Quarterly Due Dates: Payments are due in April, June, September, and January. Mark these dates on your calendar and set aside money regularly.
Avoid Underpayment Penalties: If you pay at least as much as you owed last year throughout the year, you're generally safe from penalties even if you owe more at filing.

Advanced Strategies — Reduce your tax burden

Smart Tax Planning

Maximize Business Deductions: Home office, vehicle use, equipment, software, health insurance, retirement contributions—legitimate business expenses lower your tax bill.
Explore Business Structures: Once your income grows, different business structures like S-Corps can provide tax advantages. Talk to an accountant about what makes sense for you.
