Self-employment tax is the Social Security and Medicare tax connected to working for yourself. It is separate from federal income tax, although both can be part of the same return. A clear record of your income, expenses, and payments helps make the filing conversation more useful.
What self-employment tax covers
When you are an employee, Social Security and Medicare taxes are usually withheld from your paycheck and your employer pays a matching share. When you are self-employed, there is no employer withholding that share. The IRS generally describes self-employment tax as 15.3%, made up of Social Security and Medicare taxes, but that rate is not a complete personal tax calculation.
Federal and state income tax, W-2 wages, household income, deductions, credits, and the structure of the business can all affect the larger return. The IRS self-employment tax overview is the right current reference for the underlying rules.
Start with net earnings and good records
For many self-employed people, the question starts with profit, not every dollar deposited into an account. Keep invoices, payment-platform summaries, 1099 forms, receipts, mileage records, and notes about major purchases together. The self-employed deductions worksheet offers a practical place to organize those records.
The published rate should not be applied to every sale as a shortcut. The IRS calculation has its own rules, and the details of your return still matter. A set-aside account can be a useful cash-management habit, but it does not replace a review of the actual records.
Schedule C and separate business returns are different
Schedule C generally reports sole-proprietor income and expenses as part of an individual Form 1040 return. It is common for freelancers, contractors, gig workers, and many one-owner businesses. Partnerships, S-Corporations, and corporations have separate entity returns. An LLC can be taxed differently depending on ownership and election.
JC Tax Services keeps those paths distinct. Schedule C preparation starts around $250+, while separate entity returns for partnerships and S-Corporations start around $600, subject to review. If income changes, you begin a new line of work, buy major equipment, move, or change business structure, bring that information forward early.
Keep estimated payments separate
Estimated tax payments may cover income tax and self-employment tax during the year. Save the date, amount, tax year, payment method, and confirmation number separately from operating expenses. The quarterly taxes guide explains a practical routine for organizing those records.

Frequently asked questions
Questions about self-employment tax
Is self-employment tax the same as income tax?
No. Self-employment tax generally refers to Social Security and Medicare taxes for people who work for themselves. Income tax is a separate part of the federal tax picture. Both can apply on the same return.
Do I owe self-employment tax if I have a side business?
You may. The answer depends on your net earnings and the facts of the activity. The IRS generally requires Schedule SE when net earnings from self-employment are $400 or more, subject to special rules and exceptions.
Is an LLC always subject to self-employment tax?
No. An LLC can be taxed in different ways depending on ownership and tax election. A one-owner LLC may report activity on Schedule C, while partnerships, S-Corporations, and corporations have separate filing considerations.
