1099 vs W-2 Taxes 2026: Which Costs You More?
A 1099 independent contractor pays 15.3% self-employment tax — the full FICA amount. A W-2 employee pays only 7.65% because the employer covers the other half. On $50,000 net income, that difference is $3,825 per year. However, 1099 workers get powerful deductions — mileage, home office, health insurance — that W-2 employees cannot claim.
Key Takeaways
- 1099 workers pay 15.3% SE tax vs 7.65% for W-2 — a gap of 7.65% on all earned income
- On $50,000, the extra SE tax burden is $3,825 before any deductions
- 1099 workers can deduct 50% of SE tax, reducing their taxable income by up to $3,533 at $50K
- Mileage deduction at 72.5 cents/mile (2026) can offset thousands in SE tax
- Solo 401(k) contributions up to $23,500 slash taxable income significantly
How Much More Tax Does a 1099 Worker Pay?
The core difference is who pays the employer share of FICA. W-2 employers pay 7.65% on top of your salary — you never see it. As a 1099 contractor, you are both employee and employer. You pay both halves yourself: 12.4% Social Security + 2.9% Medicare = 15.3% total.
The IRS does give 1099 workers one offset: you can deduct 50% of SE tax from gross income. So the actual extra cost is closer to 5.6% after the deduction — but still real money.
What Is Self-Employment Tax?
Self-employment tax covers Social Security and Medicare for people who work for themselves. It applies to net profit above $400. The IRS calculates it on 92.35% of your net earnings (not 100%) to simulate the employer deduction a W-2 worker would receive.
The IRS states: "If you are self-employed, you are responsible for paying the full 15.3% self-employment tax. However, you can deduct one-half of the self-employment tax as an adjustment to income."
- Social Security: 12.4% on income up to $184,500 (2026 wage base)
- Medicare: 2.9% on all net earnings, no cap
- Additional Medicare: 0.9% on earnings above $200,000 single / $250,000 MFJ
- SE tax deduction: 50% of total SE tax reduces your adjusted gross income

Deductions That Close the Gap
1099 workers have access to deductions unavailable to W-2 employees. Used correctly, these can eliminate most or all of the SE tax penalty.

- Home office — $5 per square foot, up to $1,500 (simplified method). Or deduct actual expenses proportionally.
- Health insurance — 100% of premiums deductible on Schedule 1 if you are not eligible for employer coverage.
- Solo 401(k) — Contribute up to $23,500 as employee + 25% of net earnings as employer. Massive taxable income reduction.
- Business expenses — Phone, internet, equipment, software — deductible if used for business.
- W-2 employees cannot deduct unreimbursed work expenses under current law (suspended through 2025, extended 2026)
- W-2 workers cannot contribute to a Solo 401(k) — only employer-sponsored plans
- W-2 workers cannot deduct home office unless an employer mandates remote work with no office available
