1099 vs W-2 (2026): The Definitive Difference and How to Pay Each

A W-2 worker is an employee whose taxes you withhold and whose work you control; a 1099 worker is an independent contractor who runs their own business, sets their own methods, and pays their own taxes. The core test is control: if you direct how the work gets done — hours, tools, process — the worker is almost certainly a W-2 employee, no matter what the contract says. Getting this wrong is one of the most expensive mistakes a small business can make, because the IRS and state agencies assess back taxes, penalties, and interest on misclassified workers.

I’ve hired both. The label isn’t a choice you make for convenience — it’s a determination the facts make for you. Here’s the definitive breakdown.

The fundamental difference

A W-2 employee works for your business. You control what they do and how they do it, you withhold income and payroll taxes from their pay, you pay the employer share of those taxes, and you may owe them benefits and overtime. At year-end they get a W-2.

A 1099 contractor runs an independent business that you hire for a result. They control how the work gets done, supply their own tools, often serve multiple clients, and pay their own income and self-employment taxes. You report what you paid them on a 1099-NEC if it’s $600 or more in a year.

The distinction isn’t about full-time vs part-time, or salaried vs hourly. It’s about the relationship and control.

The IRS classification rules

The IRS evaluates worker status across three categories of evidence — there’s no single deciding factor:

1. Behavioral control — Do you direct how, when, and where the work is done? Do you provide training and detailed instructions? More control points to employee.
2. Financial control — Does the worker have unreimbursed expenses, their own equipment, a chance for profit or loss, and other clients? More independence points to contractor.
3. Relationship — Is there a written contract? Are there benefits? Is the work ongoing and central to your business, or project-based? Permanence and core-business work point to employee.

Many states apply a stricter ABC test, under which a worker is an employee unless the business proves all three: (A) the worker is free from control, (B) the work is outside the company’s usual business, and (C) the worker is independently established in that trade. California and several others use this. When in doubt, classify as an employee or consult a professional — the default presumption increasingly favors employee status.

Tax implications for each

For W-2 employees, you withhold federal (and usually state) income tax plus the employee’s 6.2% Social Security and 1.45% Medicare. You match the 7.65% FICA as the employer and pay federal and state unemployment tax. You deposit these on an IRS schedule and file Form 941 quarterly, Form 940 annually, and W-2s at year-end.

For 1099 contractors, you withhold nothing. The contractor pays their own income tax and the full 15.3% self-employment tax (both halves of FICA). Your only obligation is to collect a W-9 and issue a 1099-NEC if you paid them $600 or more in the year.

The cost difference is real — employees cost you an extra ~7.65% plus unemployment and any benefits — which is exactly why misclassification is tempting and exactly why agencies police it.

Misclassification risk

Calling an employee a contractor to save on payroll taxes is a costly gamble. If you’re caught — through an audit, a worker’s unemployment claim, or a complaint — you can owe:

• Back payroll taxes you should have withheld and paid.
• Penalties and interest on those amounts.
• Liability for benefits, overtime, and workers’ comp.
• State penalties, which can be steep under ABC-test states.

The safe move: classify based on the actual working relationship, document your reasoning, and use a written contractor agreement for genuine 1099 relationships. If a worker functions like an employee, pay them as one.

How to pay each correctly

W-2 employees go through payroll: collect a W-4 and I-9, withhold and remit taxes each run, and issue a W-2. Full-service payroll software handles the withholding, deposits, and filings.

1099 contractors you pay by invoice or direct deposit: collect a W-9 up front, track total payments, and file a 1099-NEC if they hit $600. Many payroll platforms also pay contractors and file 1099s for you. For the contractor side specifically, see my Gusto contractor payments guide.

Making payroll easier with Gusto

Gusto handles both worker types in one place, which is why I recommend it whether you’re paying W-2 employees, 1099 contractors, or a mix. For employees, it’s full-service: it calculates and withholds income and payroll taxes, deposits them on schedule, files your 941s, 940, and state returns, and issues W-2s. For contractors, it pays them by direct deposit and files 1099-NECs automatically. Employee payroll starts at $49/month plus $6 per employee (Simple), and there’s a Contractor Only plan at $35/month — free for six months — plus $6 per contractor if you pay only freelancers.

New customers who sign up through a referral link get a Visa gift card after their first paid payroll — $100 for fewer than 10 workers, $200 for 10 or more — plus three months free. There’s no coupon to enter; the offer applies through the referral link.

Frequently asked questions

What is the main difference between a 1099 and a W-2 worker?

A W-2 worker is an employee whose taxes you withhold and whose work you direct. A 1099 worker is an independent contractor who controls how the work is done, serves their own business, and pays their own taxes. The deciding factor is control over the work, not the job title or hours.

Is it cheaper to hire a 1099 contractor or a W-2 employee?

A 1099 contractor costs less directly because you don’t pay the employer’s 7.65% payroll tax, unemployment tax, or benefits. But you can’t classify someone as a contractor just to save money — if the relationship is actually employment, misclassification penalties usually outweigh the savings.

How do I know if a worker is a contractor or an employee?

Apply the IRS tests for behavioral control, financial control, and the relationship. If you direct how, when, and where the work is done and it’s central to your business, the worker is likely an employee. Many states use a stricter ABC test that presumes employee status unless you prove independence.

What happens if I misclassify an employee as a 1099 contractor?

You can owe back payroll taxes, penalties, interest, and liability for benefits, overtime, and workers’ comp. Audits, unemployment claims, and worker complaints all trigger reviews. Classify based on the real relationship, document it, and pay genuine employees through payroll.
