The core math: 7.65% vs 15.3% on 92.35%
The entire W-2 vs 1099 question comes down to one asymmetry: who pays the employer's half of payroll tax.
As a W-2 employee in 2026, you pay 7.65% of your salary in FICA tax — 6.2% Social Security (on wages up to the $184,500 wage base) plus 1.45% Medicare. Your employer quietly pays a matching 7.65% on top. You never see it, but it's part of what you cost.
As a 1099 independent contractor, you are both employer and employee, so you pay both halves: the self-employment tax is 15.3% — 12.4% Social Security plus 2.9% Medicare — applied to 92.35% of your net earnings (the 92.35% excludes the "employer half," per IRS Schedule SE rules). On your gross contract amount, that works out to an effective rate of about 14.13%. No employer match, no free half.
This calculator compares cash before income tax on both sides, so it's apples-to-apples: W-2 salary minus 7.65% FICA, versus the contract amount minus 14.13% self-employment tax minus whatever you pay yourself for health insurance.
Worked example: $100,000 W-2 vs $120,000 contract
| Step | Math | Result |
|---|---|---|
| W-2 salary | — | $100,000 |
| W-2 FICA (7.65%) | $100,000 × 7.65% | −$7,650 |
| W-2 net cash | $92,350 | |
| 1099 contract amount | — | $120,000 |
| Self-employment tax | $120,000 × 92.35% × 15.3% | −$16,955 |
| Self-paid health insurance | — | −$6,000 |
| 1099 net cash | $97,045 |
The $120,000 contract beats the $100,000 salary by $4,695 a year — after tax, after insurance. Now the break-even question: how low could the contract go and still tie?
| Step | Math | Result |
|---|---|---|
| Target (W-2 net) + insurance | $92,350 + $6,000 | $98,350 |
| Break-even contract | $98,350 ÷ (1 − 14.13%) | $114,533 |
| Premium over W-2 salary | ($114,533 − $100,000) ÷ $100,000 | 14.5% |
So with $6,000/year of self-paid insurance, the contract needs to pay about 14.5% more than the salary to break even. Change the insurance number and watch that premium move — it's the single biggest lever in the comparison.
The costs this calculator can't see
The math above is only payroll tax and insurance. Contracting carries a second layer of costs that no formula prices for you:
- Unpaid time off. No paid vacation, no sick days, no paid holidays. Two unpaid weeks a year is ~4% of your income gone.
- Quarterly estimated taxes. The IRS wants its money four times a year (Form 1040-ES), and underpayment penalties are real. Budgeting discipline becomes a job skill.
- Lost safety nets. No unemployment insurance, no workers' compensation, no employer disability coverage.
- Retirement. No 401(k) match — though you gain access to a Solo 401(k) or SEP-IRA with higher contribution limits than an employee 401(k).
- Admin overhead. Invoicing, bookkeeping, finding the next contract. Billable hours are not the same as working hours.
A note on misclassification
If a "contract" offer comes with set hours, a company laptop, mandatory meetings, and a boss who approves your vacation, you may legally be an employee regardless of what the paperwork says. The IRS uses behavioral, financial, and relationship tests — and misclassification costs you the employer's tax half plus benefits. If the arrangement smells like employment, that's a legal question worth asking before it's a tax question.
Data sources and assumptions
- FICA employee share: 7.65% (6.2% Social Security up to the $184,500 wage base + 1.45% Medicare), per Social Security Administration 2026 announcements.
- Self-employment tax: 15.3% (12.4% + 2.9%) on 92.35% of net earnings, per IRS Schedule SE instructions — effective ~14.13% of gross contract amount.
- Not modeled: federal/state/local income tax, quarterly estimated payments and penalties, business expenses and deductions (including the self-employed health insurance deduction), the 0.9% Additional Medicare Tax above $200k/$250k, unpaid time off, and lost employer benefits.
Frequently asked questions
Why is self-employment tax calculated on 92.35% of earnings instead of 100%?
Because the tax code gives you a break that mirrors what employers get. An employer deducts its half of payroll tax as a business expense; since a self-employed person is both employer and employee, the IRS lets you exclude the 'employer half' (7.65%) from the taxable base — 100% − 7.65% = 92.35%. You then pay the full 15.3% (12.4% Social Security + 2.9% Medicare) on that reduced base. The effective rate on your gross contract amount is about 14.13%, which is exactly what this calculator uses.
Do I really have to pay quarterly estimated taxes as a 1099 contractor?
Yes. Unlike W-2 income, nothing is withheld from 1099 payments, so the IRS requires you to pay estimated tax four times a year using Form 1040-ES. Miss the schedule or underpay and you'll owe an underpayment penalty on top of the tax itself. A common rule of thumb is to set aside 25–30% of every invoice the day it arrives — in a separate account, so you never spend the IRS's money.
Can a 1099 contractor deduct health insurance premiums?
Yes — the self-employed health insurance deduction lets you deduct premiums for yourself, your spouse, and dependents 'above the line' (it reduces your income-tax base, though not your self-employment tax base). That's a genuine tax benefit W-2 employees don't get for their share of premiums. This calculator doesn't model income tax at all, so the deduction isn't reflected in the numbers — but it's one of the first things to discuss with a tax professional.
Is the 'charge 30% more as a contractor' rule accurate?
It's a folk heuristic with a grain of truth. The precise payroll-tax-only break-even for a contractor with no self-paid insurance is about 7.5% above the W-2 salary — but once you add self-paid health insurance ($6,000–$12,000/year is typical for an individual plan in 2026), unpaid vacation and sick days, and the loss of employer benefits, the real break-even usually lands between 15% and 30%. Use this calculator for your exact number instead of the rule of thumb.
What about the 0.9% Additional Medicare Tax?
It applies to self-employment income too: an extra 0.9% on earnings above $200,000 (single) or $250,000 (married filing jointly), per IRS rules for 2026. This calculator doesn't model it, so if your contract is above those thresholds, your true break-even is slightly higher than shown.
