1099 vs W-2: how the taxes really differ (with 2026 numbers)

"1099" and "W-2" are the names of tax forms, but people use them for two ways of being paid:

• W-2 employee: your employer withholds income tax from every paycheck, pays half of your Social Security and Medicare tax, and sends you a Form W-2 in January.
• 1099 contractor: you're in business for yourself. Clients pay you the full amount with nothing withheld, and may send you a Form 1099-NEC (or a 1099-K if you're paid through an app or platform). You handle the tax yourself.

The income tax brackets are the same either way. What changes is who pays the payroll tax, when the tax is paid, and what you can deduct.

The differences at a glance

	W-2 employee	1099 contractor
Social Security and Medicare	7.65% from you, 7.65% from your employer	15.3% self-employment tax, all from you
Income tax	Withheld from each paycheck	Paid by you in quarterly estimates
Work expenses	Not deductible on your federal return	Deductible on Schedule C
QBI deduction	No	Usually up to 20% of profit (how it works)
Health insurance, retirement plan	Often provided	Your own, but premiums are deductible and you can open a SEP IRA or solo 401(k)
Unemployment, workers' comp	Usually covered	Usually not
Form you get	W-2 by early February	1099-NEC if a client paid you $2,000+ in 2026; maybe none

The payroll tax gap

On a $75,000 W-2 salary, you pay $5,738 of Social Security and Medicare tax (7.65%) and your employer pays another $5,738 that you never see.

As a contractor with $75,000 of profit, you pay $10,597 of self-employment tax. That's 15.3% of 92.35% of your profit. You get half of it back as a deduction from income, which lowers your income tax by roughly $600 to $1,200 depending on your bracket. Before that, it's about $4,860 more than the employee pays.

So a 1099 rate has to be higher than a W-2 salary just to come out even. Covering the employer's half of the payroll tax alone takes about 7.65% more. Add health insurance, retirement contributions, unpaid holidays and sick days, and your own equipment, and many people use a rule of thumb of 25% to 40% more. Your real number depends on what benefits the W-2 job offers.

Deductions can close part of the gap

Contractors deduct the ordinary and necessary costs of their business before any tax is worked out: software, a laptop, a phone share, a home office, business mileage and platform fees. Employees can't deduct unreimbursed work expenses on their federal return.

Every $1,000 of expenses saves a contractor about $141 of self-employment tax plus income tax at their bracket rate, so roughly $230 to $310 in the 12% and 22% brackets. That only applies to real business costs, and you need records for them.

You pay as you go

Nobody withholds tax from contractor income, so the IRS expects payments four times a year. For 2026 income the last one is due January 15, 2027. Miss them and you can owe an underpayment penalty, even if you pay everything in April.

A simple habit covers it: move a fixed share of every payment into a separate savings account. Our guide to how much to set aside has rates by income, and the free calculator works out each quarter's payment.

Both at once

Plenty of people have a W-2 job and a 1099 side business. Your W-2 wages count toward the Social Security wage base first ($184,500 for 2026), and you can raise your withholding at the day job with a new Form W-4 instead of sending quarterly payments. Withholding counts as if it were paid evenly through the year, which makes it a handy way to catch up late.

Who decides which one you are?

Not the contract, and not you. The IRS looks at the whole relationship under three headings:

• Behavioral control: does the business control what you do and how you do it, or only the result?
• Financial control: who provides the tools, who pays expenses, can you make or lose money, do you work for other clients?
• Type of relationship: are there employee-type benefits, and is the work expected to continue indefinitely?

If you think you're being treated as a contractor when you're really an employee, you can ask the IRS for a ruling on Form SS-8. Workers who were misclassified use Form 8919 to pay only the employee's share of Social Security and Medicare tax. States can have their own, stricter tests for unemployment insurance and labor law.
