W-2: salary minus your pre-tax health premium share, federal income tax (2026 brackets, standard deduction), Social Security (6.2% up to $184,500), Medicare (1.45%, plus 0.9% over $200,000, or $250,000 joint) and your state's income tax and payroll programs. Paid holidays and vacation are already in the salary. The 401(k) match and other benefits are added for the like-for-like total.
1099: rate × billable hours × (52 − unbilled weeks), or the contract amount, minus expenses and your own health insurance. Federal tax: self-employment tax (15.3% of 92.35% of profit, Social Security part capped), income tax after the half-SE-tax and self-employed health insurance deductions and the 20% QBI deduction (phased out across $75,000 above $201,750 of taxable income for a business without employees, $150,000 above $403,500 joint, and faster for a service business), plus Additional Medicare. State tax applies the state's rules to federal AGI, without QBI; that's an approximation for states such as Pennsylvania and New Jersey that tax self-employment income differently. Break-even values are found by searching for the rate or salary where the totals match.

Usually about 1.3 to 1.5 times the salary's hourly rate on middle incomes (more on lower salaries, a little less on high ones), and more again if you'll have long gaps between contracts. A $90,000 salary works out to $43.27 an hour over 2,080 hours. With a 4% 401(k) match, an average employer health plan, six unbilled weeks a year and $2,000 of expenses, you'd need about $59.18 an hour as a contractor to keep the same amount after taxes in a state with no income tax: 1.37 times as much. The Small Business Administration puts an employee's total cost to an employer at 1.25 to 1.4 times salary, which is the same idea seen from the other side (SBA).

| Social Security and Medicare | 7.65%, employer pays another 7.65% | 15.3% self-employment tax (half is deductible) |
| Income tax | Withheld from each paycheck | Quarterly estimated payments |

Employees pay 7.65% for Social Security and Medicare and the employer quietly pays another 7.65%. As a contractor you pay both: 15.3% on 92.35% of your profit, with the 12.4% Social Security part stopping at $184,500 in 2026 ($192,300 in 2027), plus 0.9% Additional Medicare above $200,000 ($250,000 joint). Half of it is deductible from income for income tax (IRS).
profit × 92.35% × 15.3% = Social Security part capped at the wage base
At the default contract ($108,400 of profit): $15,316, against $6,775 of Social Security and Medicare on the $90,000 salary.
Contractors who run their own business can usually deduct up to 20% of qualified business income (profit minus half the self-employment tax, self-employed health insurance and your own retirement plan contributions), limited to 20% of taxable income. The 2025 tax law made it permanent (IRS; 26 U.S.C. § 199A).
In the default example the deduction is $15,063, which recovers part of the extra self-employment tax.
In private industry, benefits make up 30.0% of employer spending on compensation: $14.07 of $46.89 an hour in June 2026, including 7.5% paid leave, 7.4% health insurance, 3.3% retirement and 7.2% legally required benefits such as the employer's Social Security and Medicare (BLS). Health insurance is the big one: the average premium for single coverage was $9,325 in 2025, of which workers paid $1,440; family coverage was $26,993, with workers paying $6,850 (KFF). Enter your own figures; if you'd have family coverage, the contract rate you need rises sharply.
A salary pays you for holidays, vacation and sick days; private-industry workers average 11 vacation days after a year and 7 sick days (BLS), plus paid holidays. As a contractor you only earn when you bill, and there are often gaps between contracts. That's why the "unbilled weeks" input matters so much:
| Unbilled weeks | Billable weeks | Rate needed |
|---|---|---|
| 2 weeks | 50 | $54.45 |
| 4 weeks | 48 | $56.72 |
| 6 weeks | 46 | $59.18 |
| 8 weeks | 44 | $61.87 |
| 10 weeks | 42 | $64.82 |
Self-employed people can usually deduct their health insurance premiums from income (not from self-employment tax) if they aren't eligible for an employer plan (IRS Form 7206). Marketplace plans may come with premium tax credits based on income, but the extra subsidies of 2021–2025 ended after 2025, so many people pay more in 2026; check healthcare.gov for your price (ASTHO). If you'd join a spouse's employer plan instead, enter what that adds to your household's premium; that's usually far less than $9,325, which lowers the rate you need, but you can't take the self-employed health insurance deduction for months you could join an employer plan, so the calculator will slightly understate your tax in that case.
You can still save a lot, just without a match. In 2026 a Solo 401(k) allows $24,500 of your own contributions (plus catch-ups from 50) and an employer contribution of up to 25% of compensation (about 20% of net self-employment earnings), up to $72,000 in total; a SEP-IRA allows the employer part only (IRS; IRS). Those contributions reduce income tax but not self-employment tax, and they also reduce the income your QBI deduction is based on.
Expenses reduce both income tax and self-employment tax, but you still pay for them, so a contract with high costs needs a higher rate.
Nobody withholds tax from contract pay, so you pay estimated tax four times a year: for 2026, by April 15, June 15 and September 15, 2026 and January 15, 2027 (IRS). The quarterly tax calculator works out the amounts, and the self-employment tax calculator shows how much of each payment to set aside. Clients send a Form 1099-NEC if they pay you $2,000 or more in a year for payments from 2026, up from $600 (IRS); you owe tax on all your income whether or not you get one.
The label on your contract doesn't decide it. The IRS looks at behavioral control (who decides how the work is done), financial control (who pays expenses, can you profit or lose) and the relationship (benefits, permanence) (IRS). Under federal wage law, the Labor Department proposed a new test in February 2026; its 2024 rule still applies in private lawsuits (Federal Register). Several states are stricter: California's "ABC test" presumes you're an employee unless you're free from the company's control, the work is outside its usual business, and you run an independent business of that kind (California); Massachusetts, New Jersey and Illinois use versions of it for some laws.
Staffing firms often offer three ways to pay for the same role: W-2 through the agency (taxes withheld, sometimes benefits), 1099 to you as a sole proprietor, or corp-to-corp (C2C) to your own company. C2C usually pays the highest rate because the agency pays no payroll tax or benefits. Taxes on C2C depend on how your company is set up; as a single-member LLC taxed as a sole proprietor it works like 1099 in this calculator.
State tax changes the picture too: at the default numbers the break-even rate is $58.27 in California and $58.90 in New York. State disability and paid-leave programs such as California's SDI come out of W-2 pay but usually don't apply to the self-employed (some states let you opt in).
It depends on the rate. At the same pay, W-2 is better because the employer pays half your payroll tax and your benefits. A 1099 contract comes out ahead only if the rate is high enough, often 1.3 to 1.5 times the salary's hourly rate, more on lower salaries.
Divide the salary by 2,080 for the hourly equivalent, then multiply by about 1.3 to 1.5 (more on lower salaries) to cover self-employment tax, benefits and unbilled time. The calculator works out your exact figure.
Self-employment tax of 15.3% on 92.35% of profit, plus income tax after the QBI and other deductions. Set aside roughly 25% to 35% of what you're paid, depending on your income and state.
They pay the employer's half of Social Security and Medicare (7.65%), partly offset by deducting half of it and by the QBI deduction.
A deduction of up to 20% of business income for the self-employed and owners of pass-through businesses, permanent since the 2025 tax law, with limits above $201,750 of taxable income ($403,500 joint) in 2026.
C2C usually pays a higher rate but you cover all taxes, insurance and benefits through your own company. Compare them after taxes as you would 1099.
Generally from business clients who pay you $2,000 or more directly in a year (from 2026). Payments by card or through apps like PayPal are reported on Form 1099-K instead, and payments to a corporation usually aren't reported. Either way, all of your income is taxable.
