1099 vs W-2: how taxes differ for contractors and employees
Updated October 22, 2026 · By the Solo Tax Optimizer team · Not tax advice
A W-2 employee and a 1099 independent contractor can earn the same number on paper and keep very different amounts. The tax rules are a big part of the reason. Here is how they differ and what each means for your take-home pay.
The quick comparison
| W-2 employee | 1099 contractor | |
|---|---|---|
| Social Security & Medicare | 7.65% (employer pays another 7.65%) | 15.3% self-employment tax on 92.35% of profit |
| How tax is paid | Withheld from each paycheck | Quarterly estimated payments |
| Business expenses | Generally not deductible | Deductible against income |
| QBI deduction | Not available on wages | Up to 20% of qualified business income |
| Retirement plan | Employer 401(k), often with a match | Solo 401(k) or SEP IRA you set up and fund |
| Health insurance | Often subsidized by employer, paid pre-tax | You buy it, but it may be deductible |
| Tax form you receive | W-2 | 1099-NEC or 1099-K (or none for small amounts) |
Payroll taxes: the biggest difference
An employee's share of Social Security and Medicare tax is 7.65%. The employer pays a matching 7.65% that never shows up on the employee's pay stub. A contractor pays both halves as self-employment tax. On $100,000 of profit, that is about $14,130, compared with $7,650 withheld from a $100,000 salary.
The contractor does get to deduct half of the self-employment tax for income tax purposes, which softens the difference slightly.
Withholding vs estimated payments
Employers withhold income and payroll taxes from every paycheck, so most employees owe little or nothing at filing time. Contractors receive their full payment and must set money aside and pay the IRS themselves through quarterly estimated taxes. Falling behind can lead to penalties, and to a large bill in April.
Deductions: the contractor's advantage
Employees generally cannot deduct work expenses on their federal return. Contractors can deduct ordinary and necessary business expenses, such as equipment, software, a home office, business travel and professional fees. These reduce both income tax and self-employment tax. See our self-employed deductions checklist.
Contractors may also qualify for the QBI deduction of up to 20% of their business income, which employees cannot claim on wages.
Benefits change the math
Beyond taxes, employees usually receive benefits that contractors must pay for themselves:
- Health insurance: employers often pay a large share of the premium. Contractors can usually deduct premiums through the self-employed health insurance deduction, but they pay the full cost.
- Retirement matching: a typical 401(k) match is free money a contractor doesn't get. Contractors can save more through a Solo 401(k), but every dollar comes from their own pocket.
- Paid time off: employees are paid for holidays and vacation. Contractors earn nothing when they aren't working.
- Unemployment and workers' compensation: employees are generally covered. Contractors are not.
So which pays more?
A contractor needs to earn noticeably more than an employee to come out even. The extra payroll tax, unpaid time off and benefits often add up to 25% to 50% or more of the salary. Deductions and the QBI deduction recover some of that. To compare a specific offer, see how to convert a salary to a 1099 hourly rate, or put both offers into our 1099 vs W-2 calculator.
Watch out for misclassification
Whether you are an employee or a contractor is decided by the actual working relationship, not by what the contract calls you. Employers who control what, when and how you work, provide your tools, and treat you like staff may be required to treat you as an employee. If you believe you have been misclassified, the IRS can make a determination through Form SS-8.
Frequently asked questions
Do 1099 contractors get a tax refund?
They can. A refund simply means you paid more during the year than you owed. Contractors who overpay their quarterly estimated taxes receive the excess back as a refund, or can apply it to next year.
Can I be both a W-2 employee and a 1099 contractor?
Yes. Many people have a W-2 job and freelance on the side. Your W-2 wages count toward the $184,500 Social Security wage base first, which can reduce the self-employment tax on your side income. You can also raise your W-2 withholding to cover tax on the side income instead of making estimated payments.
What if my employer treats me as a contractor but controls my work like an employee?
Worker classification depends on the actual relationship, such as who controls how the work is done and the financial arrangement, not on what the contract says. If you think you have been misclassified, you can ask the IRS to determine your status using Form SS-8, and you may be able to use Form 8919 to pay only the employee share of Social Security and Medicare tax.
