Introduction
Whether you hire a contractor or an employee changes your tax obligations significantly. Employees trigger payroll withholding, employer tax contributions, and unemployment taxes. Independent contractors handle their own taxes, and your main obligation is filing Form 1099-NEC when you pay them $600 or more in a year.
How the IRS tells employees and contractors apart
The IRS uses a three-category system to decide whether a worker is an employee or an independent contractor. The categories are behavioral control, financial control, and the type of relationship. No single factor is decisive — the IRS looks at the full picture of how the relationship actually works, not just what a contract says.
Behavioral control
Behavioral control looks at whether your business directs how the work gets done — not just what the end result is. The more you dictate when, where, and how someone works, and the more training you provide, the more the relationship looks like employment. A contractor typically decides their own methods.
Financial control
Financial control looks at who controls the economic side of the work. Does the worker invest in their own tools? Do they offer services to other clients? Can they make a profit or take a loss independent of your business? If yes, those factors point toward contractor status. If you reimburse expenses and pay a set hourly rate, the relationship looks more like employment.
Type of relationship
The type of relationship looks at the structure of the arrangement. A written contract calling someone a contractor doesn't override how the relationship actually functions. Contractors typically don't receive benefits like health insurance, retirement plans, or paid leave. They're usually hired for a specific project rather than indefinitely, and they don't perform core business functions.
Why classification matters for your taxes
Getting a worker's classification wrong is one of the more expensive mistakes a business can make. If the IRS determines that someone you treated as a contractor should have been an employee, your business can owe back payroll taxes, unpaid Social Security and Medicare contributions, plus penalties and interest — all for periods that may go back years.
The stakes go beyond taxes. Employees are covered by federal labor laws — minimum wage and overtime protections under the Fair Labor Standards Act (FLSA), family leave rights under the Family and Medical Leave Act (FMLA), and anti-discrimination protections enforced by the EEOC. Independent contractors are generally not covered by any of these. Misclassifying an employee as a contractor doesn't just create a tax problem — it can expose your business to Department of Labor enforcement as well.
Most business owners don't realize the IRS looks at how the relationship actually works — not what the paperwork says. A contract that calls someone a contractor won't protect you if the day-to-day arrangement looks like employment.
How taxes work for each worker type
The tax obligations your business carries depend entirely on which category the worker falls into. Employees create ongoing payroll responsibilities. Contractors create a single annual reporting obligation if you pay them enough.
Employees: what you withhold and pay
When you hire an employee, you take on three layers of tax responsibility. First, you withhold federal income tax from each paycheck based on the employee's W-4. Second, you withhold the employee's share of Social Security (6.2%) and Medicare (1.45%) taxes — and you pay a matching employer share on top of that. Third, you pay federal unemployment tax (FUTA) on the first $7,000 in wages per employee, at a rate of roughly 6%, plus applicable state unemployment taxes.
Deposit timing matters. Most employers deposit withheld income tax and FICA taxes either monthly or semiweekly, depending on their total tax liability in a prior lookback period. FUTA taxes are deposited quarterly when the accumulated liability exceeds $500. At year end, you file Form W-2 for each employee to report total wages and taxes withheld.
Independent contractors: what you report
When you hire an independent contractor, you don't withhold income tax, Social Security, or Medicare from their payments. You don't pay FUTA or state unemployment taxes on what you pay them. The contractor is responsible for their own self-employment tax — which covers both the employer and employee portions of Social Security and Medicare — and for making quarterly estimated tax payments to the IRS.
Your reporting obligation is straightforward: if you pay a contractor $600 or more during the calendar year and they're not a corporation, file Form 1099-NEC to report the total nonemployee compensation. The deadline is January 31. Before you pay a contractor for the first time, have them complete a Form W-9 — it confirms their tax classification and Taxpayer Identification Number, and tells you whether the 1099-NEC requirement applies.
FAQ
Generally, yes — at least on paper. An independent contractor pays self-employment tax at 15.3% on net earnings, which covers both the employer and employee portions of Social Security and Medicare. An employee only pays the employee half (7.65%), because the employer covers the other half. Contractors can deduct half of their self-employment tax on their federal return, which reduces the gap somewhat. A tax professional can help you figure out the net difference for your specific situation.
The IRS uses a three-category system: behavioral control, financial control, and the type of relationship. Behavioral control looks at how much direction you give over how the work is done. Financial control looks at who provides tools, who bears financial risk, and whether the worker offers services to other clients. The type of relationship looks at written contracts, benefits, and whether the work is ongoing or project-based. No single factor is decisive — the IRS weighs all of them together.
Getting it wrong is expensive. If the IRS reclassifies a contractor as an employee, your business can be on the hook for back payroll taxes, unpaid employer Social Security and Medicare contributions, plus penalties and interest — potentially covering multiple years. The Department of Labor can also pursue separate enforcement action for wage and hour violations under the FLSA. Talk to a tax professional if you're unsure about a worker's classification before you pay them.
File Form 1099-NEC when you pay a contractor $600 or more in nonemployee compensation during the calendar year and they're not a corporation. The deadline is January 31 of the following year. Have the contractor fill out a Form W-9 before you make your first payment — it gives you their Taxpayer Identification Number and confirms whether the 1099-NEC requirement applies to them.
Yes. Independent contractors are responsible for their own federal income tax and self-employment tax. Because no tax is withheld from their payments, contractors generally need to make quarterly estimated tax payments to the IRS to cover both income tax and self-employment tax. They file Schedule SE with their annual return to calculate the self-employment tax owed on net earnings of $400 or more.
Yes. The IRS and the Department of Labor use different standards to classify workers. The IRS applies its three-category common law test for federal tax purposes. The DOL applies its own economic reality test under the Fair Labor Standards Act to determine whether a worker is an employee for wage and hour purposes. A worker could be classified differently under each standard. If you're hiring someone whose status isn't clear-cut, talk to a legal professional who can assess both frameworks.
