If you’ve been offered the same job at $100,000 W-2 or $100,000 1099, those are not the same money. The 1099 version costs you roughly $7,650 more in tax, until you factor in deductions and the QBI deduction, which can swing it back the other way.
This guide explains the actual tax difference between W-2 employee and 1099 independent contractor income, and shows when each comes out ahead.
The headline difference: self-employment tax
W-2 employees split FICA (Social Security + Medicare) with their employer. Each side pays 7.65%. Independent contractors pay both halves, 15.3%, out of their own pocket. That’s the “self-employment tax.”
For 2026:
| Tax | W-2 employee (you pay) | 1099 contractor (you pay) |
|---|---|---|
| Social Security (6.2%) | Yes, up to $176,100 | Yes, doubled (12.4%) up to $176,100 |
| Medicare (1.45%) | Yes, on all wages | Yes, doubled (2.9%) on all earnings |
| Additional Medicare (0.9%) | Above $200K | Above $200K |
| Combined FICA-equivalent | 7.65% | 15.3% (up to wage base) |
So on $100,000 of gross income:
- W-2 employee: Pays $7,650 in FICA. Employer pays a separate $7,650 (invisible to you).
- 1099 contractor: Pays $14,130 in self-employment tax (15.3% × 92.35% × $100,000, the 0.9235 factor adjusts for the deduction on the employer-share portion).
But this isn’t the full picture. The 1099 contractor can deduct half of their SE tax as an adjustment to income, and can take the QBI deduction, and can deduct business expenses W-2 employees can’t.
The full apples-to-apples math
Take $100,000 of gross compensation:
W-2 employee
| Line | Amount |
|---|---|
| Gross | $100,000 |
| FICA (7.65%) | ($7,650) |
| Federal tax (single, std deduction, ~$13,449 at $100K AGI) | ($13,449) |
| Net (before state) | $78,901 |
1099 contractor (same gross, schedule C, before deductions)
| Line | Amount |
|---|---|
| Gross revenue | $100,000 |
| SE tax | ($14,130) |
| Deduction: half of SE tax | $7,065 (adjustment) |
| QBI deduction (20% of qualified business income) | ~$15,800 |
| Taxable income | $84,200 − $15,800 = $68,400 |
| Federal tax on $68,400 | ($10,500) |
| Net (before state) | $75,370 |
That’s only $3,500 worse as a contractor, not the dramatic $7,650 the headline FICA difference suggests, because:
- Half of SE tax is deductible.
- The QBI deduction shields 20% of contractor income for most service businesses (subject to phase-outs).
- Contractors can deduct business expenses (home office, equipment, travel, internet, professional development).
For most contractors, legitimate business expenses recover the $3,500 gap and then some. The cross-over point is roughly $5,000 of annual business expenses.
Quarterly estimated taxes
W-2 employees have withholding done automatically. 1099 contractors must pay quarterly estimated taxes via Form 1040-ES on:
- April 15 (Q1: Jan-Mar)
- June 15 (Q2: Apr-May)
- September 15 (Q3: Jun-Aug)
- January 15 (Q4: Sep-Dec)
You must pay either:
- 90% of current-year liability, or
- 100% of prior-year liability (110% if AGI > $150K).
Underpayment triggers an IRS penalty. Use the 1099 Tax Calculator to figure each quarter’s amount.
Business expense deductions
1099 contractors can deduct any expense that’s ordinary and necessary for the business. Common ones:
- Home office (% of rent/mortgage, utilities, internet, based on dedicated square footage)
- Equipment (computer, monitor, ergonomic chair, fully deductible up to Section 179 limits)
- Software subscriptions
- Professional development (courses, conferences, books)
- Mileage (67¢/mile for 2024 IRS standard rate, verify current year)
- Health insurance premiums (above-the-line deduction)
- Retirement contributions (Solo 401(k) up to $70,000; SEP IRA up to 25% of net SE income)
W-2 employees can deduct none of these for federal tax purposes (the Tax Cuts and Jobs Act of 2017 eliminated unreimbursed employee expenses). That’s a permanent structural advantage for contractors.
The QBI deduction (Section 199A)
The Qualified Business Income deduction lets self-employed people deduct up to 20% of net business income. Phase-outs kick in for “Specified Service Trade or Business” (SSTB) categories, consultants, lawyers, doctors, accountants, financial advisors, etc., at:
- 2026 SSTB phase-out: Begins at $232,500 single / $465,000 MFJ. Fully phased out 100K higher.
- 2026 non-SSTB phase-out: Same thresholds, but you can use W-2 wages paid and unadjusted basis as alternative limits.
For most freelance contractors below those income thresholds, QBI shields a clean 20%.
Retirement plans
This is where contractors actually win.
| Plan | W-2 employee limit | 1099 contractor limit (2026) |
|---|---|---|
| 401(k) elective | $23,500 | , |
| Solo 401(k) total | , | $70,000 |
| SEP IRA | , | 25% of net SE income, up to $70,000 |
| SIMPLE IRA | , | $16,000 |
A Solo 401(k) lets you contribute as both employee ($23,500 elective) AND employer (up to 25% of net SE income, capped at $70K combined). For a $200K-revenue freelancer, that can be $50,000+ of tax-deferred space.
What to charge as a 1099
If you’re moving from a $100K W-2 job to 1099, your equivalent rate should be roughly 30-40% higher to maintain the same net income, accounting for:
- Doubled FICA (+7.65 percentage points)
- Lost benefits: health insurance ($6-12K/year), 401(k) match ($3-10K), paid vacation/sick (2 weeks = ~8% of salary)
- Self-funded retirement contributions
- Periods between contracts (utilization < 100%)
So a $100K W-2 job is roughly equivalent to a $135-145K 1099 rate before benefits.

Common mistakes
Not paying quarterly estimates. You’ll owe penalties at tax time.
Treating gross 1099 income as take-home. It isn’t. Set aside 25-35% of every check for tax + retirement.
Mixing personal and business expenses. Maintain a separate business bank account and credit card. Audit risk goes up dramatically if you commingle.
Skipping the home office deduction because you’re “afraid of audit.” IRS data shows home office deductions don’t materially raise audit risk if used legitimately. The deduction is worth several thousand a year for most home-based freelancers.
Misclassifying as 1099 when you should be W-2. The IRS uses a 3-factor test (behavioral control, financial control, type of relationship). A “1099” job that’s full-time, at the employer’s direction, with no autonomy, is misclassified and can be challenged.
When 1099 is better than W-2
- You have significant deductible expenses (home office, equipment, software).
- You can max a Solo 401(k) or SEP IRA, far more retirement space.
- You value the autonomy (set your own hours, multiple clients).
- You can negotiate a 30-40% rate premium over the W-2 equivalent.
When W-2 is better than 1099
- Employer-paid health insurance (often $10-20K/year value).
- 401(k) match (free money you can’t replicate).
- Predictable bi-weekly paychecks.
- You’re in an SSTB above the QBI phase-out.
- You hate bookkeeping and tax filing complexity.
Other countries
The W-2 vs 1099 distinction is uniquely US:
- UK, PAYE employees vs IR35-inside vs outside IR35 contractors (very different math).
- Canada, T4 employees vs T4A contractors.
- Australia, PAYG employees vs ABN/sole-trader contractors.
- India, Salaried (TDS) vs professional income (presumptive 44ADA, 50% allowable expense).
