What Does W-2 vs 1099 Actually Pay You?

The primary reason is the structure of FICA (Social Security and Medicare) taxes. Under IRC §3101 and §3111, when you are a W-2 employee, your employer pays half of your FICA taxes (6.2% SS + 1.45% Medicare = 7.65%) as a business expense that does not appear in your gross wages. You pay only the other half.

When you are self-employed, you are both the employer and employee. You pay both halves — 15.3% of net self-employment income (after the 92.35% factor from IRC §1402(a)). On $130,000 of net self-employment income, that is roughly $18,000 in SE tax versus roughly $9,000 in employee FICA on the same gross amount. The above-the-line deduction for half of SE tax (IRC §164(f)) partially mitigates this, but the net burden remains higher than W-2.

SE tax is the self-employed equivalent of FICA, computed on Schedule SE (Form 1040). The formula per IRC §1402(a):

• Step 1: Net earnings from self-employment = Schedule C net profit × 0.9235. The 7.65% reduction is an effective deduction for the “employer half” paid by self-employed taxpayers on their own behalf.
• Step 2: Social Security component (12.4%): Applied to net earnings up to the SS wage base ($176,100 for 2025). Earnings above this cap owe no additional SS tax.
• Step 3: Medicare component (2.9%): Applied to all net earnings with no cap.
• Step 4: Additional Medicare Tax (0.9%): Per IRC §3101(b)(2), applies above $200,000 (single) / $250,000 (MFJ).

Half of the resulting SE tax is deductible above-the-line on Form 1040 (IRC §164(f)), reducing taxable income for income tax purposes.

The §199A Qualified Business Income (QBI) deduction, enacted by the Tax Cuts and Jobs Act, allows eligible self-employed individuals and pass-through entity owners to deduct up to 20% of qualified business income. This partially offsets the tax disadvantage of self-employment.

For most sole proprietors and single-member LLCs below the income thresholds ($197,300 single / $394,600 MFJ for 2025): the deduction is straightforward — 20% of Schedule C net profit, capped at 20% of taxable income before the QBI deduction.

Above the thresholds: The deduction phases out over $50,000 (single) / $100,000 (MFJ) and becomes subject to a W-2 wage limitation. Sole proprietors with no employees have no W-2 wages to unlock this limit, so the deduction phases to zero entirely above the full phase-out ceiling. W-2 employees receive no QBI deduction — wages are not QBI.

SSTB caveat: Specified Service Trade or Business owners (law, consulting, financial services, etc.) face additional limitations above the phase-out. This calculator applies general QBI rules without SSTB restrictions.

The most financially significant employer benefits for the W-2 vs 1099 comparison are:

• Employer-paid health insurance (IRC §106): The employer’s contribution toward health premiums is tax-free to the employee. For 2025, the average employer contribution for single coverage is roughly $7,500–$9,000/yr; for family coverage, $15,000–$20,000/yr. Self-employed workers can deduct their premiums (IRC §162(l)), but they still pay the full premium out-of-pocket first.
• 401(k) employer match: A 3–6% employer match on a $120,000 salary is $3,600–$7,200/yr in deferred compensation the contractor foregoes. Contributions grow tax-deferred and often vest over 2–4 years.
• Paid time off: 15 days of PTO at $120,000/yr is roughly $6,900/yr. A 1099 contractor who takes equivalent time off simply does not bill for it — they must build that cost into their rate.

Benefits not modeled here but worth considering: employer-paid life and disability insurance, FSA/HSA contributions, commuter benefits, professional development, and liability coverage.

Yes. Schedule C allows self-employed individuals to deduct ordinary and necessary business expenses (IRC §162). Common deductible expenses include:

• Home office: Dedicated workspace using regular exclusive use — either simplified method ($5/sq ft, up to 300 sq ft) or actual expenses (prorated by office percentage of home square footage).
• Equipment and technology: Computers, monitors, software subscriptions, and other tools used in the business. Subject to §179 expensing or bonus depreciation.
• Professional services: CPA fees, legal fees directly related to the business.
• Business travel and vehicle: Actual vehicle expenses or standard mileage rate (67 cents/mile for 2024; 2025 rate TBD). Must be documented.
• Health insurance premiums (IRC §162(l)): Above-the-line deduction, not a Schedule C deduction. Reduces AGI directly.
• Retirement contributions: SEP-IRA (up to 25% of net self-employment income, max $70,000 for 2025) or Solo 401(k) (employee deferral + employer contribution) are deductible and not reflected in this calculator.

W-2 employees, by contrast, cannot deduct unreimbursed employee business expenses at the federal level since the Tax Cuts and Jobs Act eliminated that deduction for tax years 2018–2025.

Use this calculator’s breakeven output as your starting point. Once you know the gross annual revenue required to match the W-2 total compensation, divide by your expected billable hours.

A reasonable workload assumption: 2,000 hours/year (50 weeks × 40 hours, with 2 weeks for non-billable time, sick leave, and administration). For a $153,000 annual breakeven, that implies $76.50/hour. But most contractors bill fewer than 2,000 hours because of unbillable time between engagements, business development, and the administrative overhead of running a business.

Conservative rule: bill at breakeven_revenue ÷ 1,700 hours for a solo practice. The remaining 300 hours of your ~2,000-hour work year are absorbed by non-revenue-generating work. At 1,700 billable hours and a $153,000 breakeven, your minimum rate would be roughly $90/hour.

Do not anchor to your W-2 hourly equivalent (salary ÷ 2,080). That ignores SE tax, benefits, and overhead entirely.

Yes — in the same way W-2 income does, assuming earnings are below the wage base. The Social Security Administration counts net self-employment income that generates SE tax as “covered earnings” for Social Security benefit calculation purposes. You accrue the same credits as a W-2 worker paying the same dollar amount into the system.

The important distinction: as a 1099 worker, you pay both halves of FICA yourself. The 12.4% SS contribution means you are building Social Security credits at the same rate as a W-2 worker who earns the same amount (whose employer invisibly contributes the employer half). Both paths generate the same Social Security record if the net taxable amounts are equal.

If you elect S-Corporation taxation as a self-employed person, distributions above your owner salary are exempt from FICA — which reduces SE tax but also reduces the wage base reported to the SSA, potentially affecting future Social Security benefits.

Self-employed workers must make quarterly estimated tax payments (Form 1040-ES) if they expect to owe at least $1,000 in tax for the year. Underpayment triggers a penalty under IRC §6654, currently based on the federal short-term rate plus 3%.

Due dates: April 15 · June 16 · September 15 · January 15 of the following year. Missing a payment doesn’t just trigger a penalty at year-end — each quarter’s underpayment is penalized separately.

Two safe harbor approaches:

• 100% of prior year tax: Pay estimated taxes equal to 100% of last year’s total tax liability (110% if AGI exceeded $150,000). This guarantees no underpayment penalty regardless of actual current-year income.
• 90% of current year tax: Estimate current year income and pay 90% of the expected liability across the four quarters.

Practical approach: set aside 25–30% of each payment received into a dedicated account for taxes. Pay quarterly from that account. This avoids cash flow surprises and keeps you in safe harbor.
