Understanding Self-Employment Tax for Freelancers
Self-employment tax is a mandatory federal tax consisting of Social Security and Medicare taxes (the FICA equivalent for non-W-2 workers). The total 15.3% self-employment tax rate covers both the employer share (7.65%) and the employee share (7.65%), assessed directly on your net earnings from self-employment.
If you operate as a sole proprietor, independent contractor, or LLC member, you report this liability on Schedule SE (Form 1040). Because employers do not withhold these funds automatically, tracking these obligations ensures you send accurate estimated quarterly tax payments to the IRS without facing underpayment penalties.
How to Calculate Self-Employment Tax
Step 1: Net Business Profit × 0.9235 = Taxable SE Income
Step 2: Taxable SE Income × 0.153 = Total Self-Employment TaxThe IRS applies the 0.9235 multiplier so you only pay tax on 92.35% of your net profits. This mirrors the payroll tax deduction corporate employers get.
Example calculation: If your 1099 net profit is $80,000, your taxable base is $73,880 ($80,000 × 0.9235). Your total self-employment tax equals $11,303.64 ($73,880 × 0.153). That breaks down to $9,161.12 for Social Security (12.4%) and $2,142.52 for Medicare (2.9%).
2026 Social Security Wage Base and Tax Deductions
The 12.4% Social Security portion only applies up to the annual Social Security wage base limit (projected around $170,000–$176,000 for 2026). Any net earnings above this threshold are exempt from Social Security tax, though the 2.9% Medicare tax applies to all net earnings without a limit.
You also qualify for an above-the-line deduction for one-half of self-employment tax on Form 1040. If you owe $10,000 in SE tax, you deduct $5,000 directly from your gross income, reducing your overall federal income tax liability.
Frequently Asked Questions
What is the self-employment tax rate for 2026?
The self-employment tax rate is 15.3%. This combines 12.4% for Social Security and 2.9% for Medicare. The Social Security portion is capped at the annual wage base, while Medicare applies to 100% of taxable net profit.
How do I calculate self-employment tax?
Multiply your annual net profit by 92.35% (0.9235) on Schedule SE to get your net taxable earnings. Then, multiply that amount by 15.3% (0.153) to determine your total tax liability.
Do I have to pay self-employment tax if I have a side job?
Yes. You must file Schedule SE and pay self-employment tax if your net side gig earnings reach $400 or more during the year, even if you already have taxes withheld from a regular W-2 job.
Is self-employment tax the same as income tax?
No. Self-employment tax is strictly for Social Security and Medicare (FICA equivalent). Federal and state income taxes are calculated separately based on your tax bracket after subtracting deductions.
How much should I set aside for self-employment tax?
Setting aside 25% to 30% of each client payment is the general standard. This covers your 15.3% self-employment tax while leaving enough to pay your quarterly federal and state income taxes.
