Understanding Self Employment Tax in the USA

If you’re a freelancer, gig worker, or own a small business in the United States, you’re responsible for paying self-employment tax. This tax includes Social Security and Medicare contributions, similar to what employees and employers share, but you pay the full portion yourself.

What Is Included in Self Employment Tax?

• Social Security Tax: 12.4%
• Medicare Tax: 2.9%
• Total: 15.3%

Who Pays Self Employment Tax?

• Freelancers and gig workers (Uber, Fiverr, Upwork)
• Sole proprietors and small business owners
• Partners in a partnership

Schedule SE and Tax Filing

You’ll report your income on Schedule C and calculate your self-employment tax using Schedule SE. This amount is added to your regular income tax obligation when filing your return.

Can I Deduct Part of This Tax?

Yes! You can deduct half of your self-employment tax from your taxable income. This is not a direct reduction of tax owed, but it does reduce the income on which you pay federal tax.

What Is the Income Limit for Social Security Portion?

For 2025, only the first $168,600 of net income is subject to the 12.4% Social Security portion. Medicare (2.9%) applies to all net earnings, with an additional 0.9% surtax for income above $200,000 (single) or $250,000 (married filing jointly).

Example Calculation

Let’s say your net self-employment income is $95,000. After the 7.65% business deduction, your adjusted net earnings become ~$87,732. Applying 15.3%, your self-employment tax is approximately $13,420, of which ~$6,710 is deductible.

Planning Tips

• Set aside 20–30% of your income for taxes (SE + income tax)
• Track all business expenses to reduce taxable income
• Consider forming an LLC or S-corp for tax efficiency
