1099 vs W-2 in 2026: The True Cost of Being a Contractor
A $100,000 W-2 salary and a $100,000 1099 contract are not equivalent.

In Illinois (single filer, no business expenses), engine-computed 1099 take-home at $100,000 is $67,337 vs $74,230 W-2 — a $6,893 annual gap. To match W-2 net pay, the contract must pay approximately $111,333.

What W-2 Employees Get That Contractors Don't
- Employer FICA match (7.65%): W-2 employers pay the employer share of Social Security and Medicare. Contractors cover both halves via self-employment tax.
- Employer health insurance: Average employer contribution approximately $7,000/year (estimate — source: KFF Employer Health Benefits Survey 2024). Contractors typically purchase individual coverage.
- 401(k) match: Many employers match a portion of employee deferrals — tax-advantaged compensation not available without an employer plan.
- PTO / sick leave: Paid time off has cash value — a 10-day PTO policy on $100,000 salary is worth roughly $3,850/year in gross wages (estimate).
- Workers' comp coverage: Employers carry workers' compensation insurance; independent contractors typically do not.
1099 Tax Advantages
- Home office deduction: Deductible if you use part of your home exclusively and regularly for business (IRS rules apply).
- Business expense deductions: Equipment, software, travel, and professional development reduce net self-employment income and income tax.
- Solo 401(k): Self-employed workers may contribute as both employee and employer. Total limits depend on net earnings — see IRS 401(k) contribution limits for current year figures.
- SEP-IRA: Simplified employee pension plans allow employer contributions up to 25% of net self-employment earnings, subject to IRS caps.
- QBI deduction: For qualifying taxpayers, up to 20% of qualified business income may be deductible on the federal return — reducing effective income tax at higher earnings.

Self-employment tax combines the employee and employer shares of Social Security and Medicare — 15.30% on 92.35% of net self-employment income per IRS Schedule SE instructions. W-2 employees pay only the 7.65% employee share through paycheck withholding.
Self-employed individuals may deduct health insurance premiums for themselves, spouse, and dependents above the line on Form 1040 if they are not eligible for employer-sponsored coverage elsewhere. Rules and limits are in IRS Publication 535. This deduction reduces income tax but not self-employment tax on Schedule SE net earnings.
The qualified business income (QBI) deduction under IRC Section 199A allows eligible self-employed taxpayers and pass-through business owners to deduct up to 20% of qualified business income on their federal return, subject to income thresholds and business-type limits. See IRS.gov for current rules — not all contractors qualify.
An S-Corp can change how income is classified (salary vs distributions), which may affect self-employment tax. The optimal structure depends on your income, reasonable salary requirements, and administrative costs. Consult a tax professional before electing S-Corp status — this article presents engine-computed tax comparisons only.
Self-employed workers generally pay estimated federal tax quarterly using Form 1040-ES when withholding will not cover their expected liability. IRS Publication 505 covers safe harbor and payment schedules. The ExactTakeHome quarterly tax calculator estimates federal, SE, and state amounts.
