🇺🇸 What “Self-Employed” Means (and Why It Matters)
If you run your own business — as a sole proprietor, freelancer, 1099 contractor, or independent contractor — you’re considered self-employed. According to the Internal Revenue Service (IRS), self-employment applies when you carry on a trade or business as an individual. IRS+2IRS+2
Unlike employees whose employers withhold taxes for them, self-employed individuals are responsible for calculating and paying their own taxes — both income tax and self-employment (SE) tax. IRS+1
Understanding this difference is the foundation of proper tax compliance and financial planning.
💡 What Taxes You Must Pay When Self-Employed
1. Income Tax
You pay federal income tax (and possibly state/local income tax), based on your net profit (income minus business expenses).
2. Self-Employment Tax (Social Security & Medicare)
Because there’s no employer to pay half of these taxes, self-employed people pay the full amount themselves. The SE tax covers Social Security and Medicare. IRS+1
-
SE Tax Rate (2025): 15.3% on net earnings (12.4% Social Security + 2.9% Medicare). IRS+1
-
Social Security Wage Base (2025): Social Security portion applies up to the first US $176,100 of net earnings. IRS+1
-
Additional Medicare Tax: High earners may owe an extra 0.9% Medicare tax on earnings above certain thresholds ($200,000 for singles; $250,000 for married filing jointly). IRS+1
If your net self-employment income is US $400 or more in a year, you generally must file SE tax using Schedule SE (Form 1040 or 1040-SR). IRS+1
🗂 How to Report Self-Employed Income and Expenses
Most self-employed people report their business profits (or losses) on Schedule C (Form 1040) — “Profit or Loss from Business (Sole Proprietorship)”. IRS+1
From gross income you deduct allowable business expenses (supplies, equipment, business use of home or car, etc.), leaving you with “net profit.” That net profit is what counts for income tax and self-employment tax.
You then use Schedule SE to compute self-employment tax due. IRS+1
Also important: you may deduct half of your self-employment tax when computing your adjusted gross income (AGI). This is a beneficial deduction available only to self-employed people. IRS
📆 Estimated Quarterly Tax Payments: Don’t Wait Until April
Because taxes aren’t withheld automatically, many self-employed individuals must make quarterly estimated tax payments. If you expect to owe US $1,000 or more in federal tax (income + SE tax) for the year, quarterly payments are required. NerdWallet+1
Typical 2025 deadlines (for most people) are:
-
April 15
-
June 15 / June 16
-
September 15
-
January 15 (of the following year) Business.org+1
Failing to pay estimated taxes — or underpaying — can result in IRS penalties. IRS+1
Pro Tip: If you also have a regular W-2 job, you might adjust withholding there to help cover your self-employment taxes instead of doing quarterly payments. Many self-employed people use this “withholding + self-employed income” mix to simplify tax management. TurboTax+1
✅ Tax Deductions & Tips for Self-Employed People
One of the big advantages of being self-employed: you can deduct many business expenses to reduce taxable income. Some common deductions:
-
Office supplies, equipment, software
-
Business use of home (home office) or vehicle (business miles)
-
Internet, phone, utilities used for work
-
Health insurance (self-employed may deduct qualifying premiums) IRS+1
-
Other ordinary and necessary business expenses
Deducting legitimate expenses can significantly lower both your income tax and self-employment tax burden.
Important: Keep clear records — receipts, logs (for mileage or home office use), and documentation of expenses. IRS can audit, and good records are your best protection.
⚠️ Key Pitfalls to Avoid
-
Mixing business and personal expenses: Only business-related expenses are deductible. Personal use of vehicle, phone, etc., isn’t allowed.
-
Under-estimating quarterly taxes: This can result in penalties for underpayment.
-
Misclassifying workers: If you hire others, incorrectly classifying employees as independent contractors can trigger IRS penalties. IRS+1
-
Not deducting SE tax “employer portion”: As a self-employed person, you can deduct half of the SE tax — many forget this and pay more than needed. IRS+1

🎯 Smart Tax Strategies for Self-Employed Individuals
-
Keep excellent records year-round.
Maintain organized files: receipts, invoices, logs (home office, vehicle), bank statements, 1099s, etc. This simplifies tax filing and protects you in audits. -
Separate business and personal finances.
Use a dedicated bank account or credit card for business — it makes expense tracking simpler and cleaner. -
Plan quarterly estimated payments in advance.
Estimate your yearly income, subtract likely deductions, compute tax owed — then divide by four. This avoids large tax bills or penalties. -
Use all legitimate deductions.
Don’t forget health insurance premiums (if eligible), home office deduction, vehicle miles (if business-related), equipment depreciation, and other necessary expenses. -
Consider working with a tax professional.
Especially for first-time self-employed individuals or those with complex finances, a certified accountant or tax professional can save you money and ensure compliance. -
Monitor changes in tax law.
Government tax rules change frequently — e.g., wage base for Social Security tax, additional Medicare surtax thresholds. Use IRS resources to stay updated.
