Self-employment tax explained
When you receive income reported on a 1099-NEC or 1099-K, you are responsible for taxes that W-2 employees split with their employer. Self-employment (SE) tax is 15.3% on net self-employment income: 12.4% for Social Security (on the first $176,100 of net SE income in 2025) plus 2.9% for Medicare with no income cap. An additional 0.9% Medicare surtax applies on net SE income above $200,000 (single) or $250,000 (married filing jointly). W-2 employees only see the employee half (7.65%) because their employer pays the other 7.65% — as a self-employed person, you pay both halves.
The SE tax deduction that softens the blow
The IRS allows you to deduct 50% of your SE tax from your gross income before calculating your income tax. This partial deduction exists because the employer's share of payroll taxes is deductible for businesses, and this mirrors that treatment for the self-employed. On $80,000 of net SE income: SE tax = $11,304. Deductible half = $5,652. This reduces your adjusted gross income by $5,652, saving approximately $1,243 in income tax at the 22% bracket — a meaningful offset.
Key deductions that reduce taxable self-employment income
Business expenses reduce your net SE income, which reduces both SE tax and income tax simultaneously — making them doubly valuable. Common deductions: home office (simplified method: $5/sq ft up to 300 sq ft; regular method: actual expenses × business-use percentage). Business mileage: 70 cents/mile in 2025 — keep a log with date, destination, purpose, and miles. Health insurance premiums paid for yourself, spouse, and dependents are fully deductible as an above-the-line deduction (not just a business expense). Retirement contributions to a SEP-IRA (up to 25% of net SE income, max $70,000 in 2025) or Solo 401(k) reduce taxable income significantly. Business equipment, software, professional subscriptions, and contractor payments are all deductible.
Quarterly estimated tax payments
1099 income has no automatic withholding. You must pay estimated taxes four times a year to avoid underpayment penalties. For 2025: Q1 due April 15, Q2 due June 16, Q3 due September 15, Q4 due January 15, 2026. Calculate each payment as 25% of your expected annual liability, or use the safe harbor method: pay 100% of last year's total tax liability in equal installments (110% if your prior-year AGI exceeded $150,000). Underpayment penalties run approximately 8% annualized on the shortfall.
Worked example
Freelance income: $90,000. Business expenses: $12,000. Net SE income: $78,000. SE tax: $78,000 × 0.9235 × 15.3% = $11,017. SE tax deduction: $5,509. Adjusted gross income: $90,000 − $12,000 − $5,509 = $72,491. Standard deduction (single): $15,000. Taxable income: $57,491. Federal income tax at 2025 brackets: approximately $8,538. Total federal tax burden: $11,017 + $8,538 = $19,555 — an effective rate of 21.7% on gross income. Quarterly payment: approximately $4,889 each quarter.
