What Is a Contract Employee? Classification, Taxes, and Deductions

A contract employee is an independent contractor: a self-employed worker who provides services to a business without being on that company’s payroll. The hiring company does not withhold income tax, Social Security, or Medicare from what it pays you, and you handle those obligations yourself, including a 15.3% self-employment tax that covers both Social Security and Medicare.¹ The label also changes what federal labor protections cover you and what deductions you can take at tax time.

How the Classification Is Decided

Calling someone a contractor in a written agreement does not settle the question. Two federal agencies use their own tests, and either can reclassify a worker if the day-to-day reality of the job looks like employment. A misclassified worker may owe back taxes, and the business that hired them can face penalties.²

The IRS Common Law Rules

The IRS looks at three categories of evidence:³

Behavioral control: whether the company directs how the worker does the job, or only what result it wants.
Financial control: whether the business controls how the worker is paid, reimburses expenses, and provides tools and supplies.
Type of relationship: whether there is a written contract, whether the worker receives employee-type benefits, whether the work is a key aspect of the business, and whether the arrangement is meant to continue indefinitely.

No single factor decides it. The IRS weighs the whole picture, so a worker can look like a contractor on one measure and an employee on another.

The DOL Economic Reality Test

The Department of Labor uses a separate standard under the Fair Labor Standards Act called the economic reality test, which asks whether a worker is economically dependent on the hiring company or genuinely in business for themselves.⁴ The DOL published a final rule in January 2024 updating its analysis, but its Wage and Hour Division stopped using that rule in enforcement investigations as of May 2025 and has proposed rescinding it.⁵ The framework is in flux, so watch for finalized changes.

What Control Looks Like in Practice

The biggest factor separating a contractor from an employee is who controls how the work gets done. An independent contractor picks the methods, tools, and sequence of tasks. The hiring company can specify a result, such as building a website with certain features by March 1, but cannot dictate the daily steps.⁶

That autonomy usually extends to hours, workspace, and equipment. Contractors typically set their own schedules, work where they choose, and supply their own tools. If a business starts requiring set hours, close supervision, or use of specific company systems for every task, the arrangement starts to look like employment no matter what the contract says. Financial independence matters too: contractors invest in their own equipment, carry their own insurance, take on the risk of a project losing money, and generally work with more than one client.

Taxes You Pay as a Contractor

Nothing Withheld From Your Pay

The hiring company pays the full agreed amount and reports it to the IRS. You are responsible for the taxes yourself.³

Self-Employment Tax

Because no employer is splitting payroll taxes with you, you pay the full 15.3% self-employment tax on your net earnings: 12.4% for Social Security and 2.9% for Medicare.¹ The Social Security portion applies only to earnings up to $184,500 in 2026; the Medicare portion has no cap.⁷ An additional 0.9% Medicare surtax kicks in on net self-employment income above $200,000 (or $250,000 for married couples filing jointly).

You can deduct half of your self-employment tax when calculating adjusted gross income, which mirrors the employer’s half a traditional job would cover.⁸

Form 1099-NEC Instead of a W-2

Instead of a W-2, you receive Form 1099-NEC from each client that pays you $2,000 or more during the calendar year. This threshold increased from $600 starting with payments made after December 31, 2025.⁹ If a client pays you less than that and does not issue a 1099-NEC, you still owe tax on the income; the threshold only controls whether the client has to file the form.

Quarterly Estimated Payments

With no withholding running through the year, you generally owe estimated tax four times. For 2026 the due dates are:¹⁰

First quarter: April 15, 2026
Second quarter: June 15, 2026
Third quarter: September 15, 2026
Fourth quarter: January 15, 2027

Underpaying or missing a deadline triggers a penalty based on the shortfall and how long it stays unpaid. Form 1040-ES walks through the calculation using your expected income, deductions, and credits.

Deductions That Offset the Bill

Contractors have access to deductions that ordinary employees do not, and they matter because your tax rate as a self-employed worker starts higher.

Business Expenses

You can deduct ordinary and necessary expenses tied to the work: equipment and software, professional development, business travel, mileage, the work portion of internet and phone costs, and professional liability insurance. These go on Schedule C and reduce your net self-employment income directly.

Home Office

If you use part of your home exclusively and regularly as your principal place of business, the simplified method lets you deduct $5 per square foot up to 300 square feet, capped at $1,500.¹¹ Exclusive use is the sticking point. A space that doubles as a guest room does not qualify.

Health Insurance Premiums

If you are not eligible for a health plan through a spouse’s employer, you can deduct 100% of your health insurance premiums as an adjustment to gross income. The plan must be established under your business, though it can be in your own name, and coverage can include your spouse, dependents, and any child under age 27.¹²

Qualified Business Income

The Section 199A qualified business income (QBI) deduction lets eligible self-employed workers deduct up to 20% of qualified business income from taxable income. The One Big Beautiful Bill Act made this deduction permanent and added a $400 minimum for taxpayers with at least $1,000 of QBI who materially participate in the business. The full 20% phases out for single filers with taxable income above $201,750 and joint filers above $403,500 in 2026. Service-based businesses such as law, accounting, and consulting face additional restrictions past those thresholds.

Setting Up Your Own Retirement Plan

With no employer-sponsored plan, you set up your own. Two common options:

SEP IRA: contributions of up to 25% of net self-employment income, capped at $72,000 for 2026. Setup is straightforward, there is no annual IRS filing, and administration is minimal. Only the employer side (you) contributes; there is no employee deferral.
Solo 401(k): both employee deferrals and employer profit-sharing contributions, which can let you save more at lower income levels than a SEP IRA. The 2026 total cap is also $72,000, plus catch-up contributions if you are 50 or older. There is more paperwork, and once plan assets pass $250,000 you must file an annual Form 5500. Some plans allow loans against the balance; a SEP IRA does not.

High income and a preference for simplicity point toward a SEP IRA. Moderate income with a goal of maximizing contributions often points toward a solo 401(k).

Paperwork Before You Start Work

Form W-9

The hiring company will ask you to complete Form W-9, which supplies your taxpayer identification number so payments can be reported to the IRS.¹³ If you do not provide a valid TIN, the company must withhold 24% of your payments as backup withholding and send it to the IRS.¹⁴ You can claim that amount as a credit when you file, but it sits with the government until then.

The Written Agreement

A solid contractor agreement covers the deliverables, payment terms and invoicing, deadlines or milestones, and how either side can end the arrangement. It should say who owns any intellectual property created during the engagement, because without an explicit clause, ownership disputes can become expensive. A confidentiality provision is common when you will see proprietary information. The contract also helps document the classification itself: language confirming that you control how the work is done, handle your own taxes, and receive no employee benefits reinforces contractor status.

Contract work is typically tied to a specific project or timeframe. It ends on a calendar date, at delivery, or when a defined milestone is met, rather than continuing indefinitely the way at-will employment does. Working with several clients at once is one of the strongest signals of true contractor status; depending on one company for all of your income over a long stretch pulls the arrangement toward employment regardless of the paperwork.

Federal Protections That Do Not Apply

Contractor status carries real gaps you need to plan around. The Fair Labor Standards Act does not cover contractors, so there is no federal minimum wage and no overtime for hours past 40 in a week.⁴ The Family and Medical Leave Act, which gives eligible employees up to 12 weeks of unpaid, job-protected leave, also does not apply.¹⁵

Most workers’ compensation systems exclude contractors, so a work injury usually means turning to your own disability or occupational accident coverage rather than a claim for benefits. State unemployment insurance is generally off the table too, so when a contract ends without another lined up, you will not collect unemployment. When something goes wrong, your route is normally a breach of contract lawsuit in civil court, not a claim with a labor board. The written agreement is the main source of your rights.

What to Do If You Have Been Misclassified

If the reality of your job looks like employment, the label on your paperwork is not the final word. You can file Form 8919 with the IRS to report your share of uncollected Social Security and Medicare taxes on wages you believe should have been subject to withholding.³ You can also ask the IRS for a formal worker status determination by filing Form SS-8.²

A misclassification finding hits the hiring business too. The IRS can pursue unpaid employment taxes, and the Department of Labor can pursue unpaid minimum wages and overtime. Under the FLSA, a wage violation can be doubled through liquidated damages equal to the unpaid amount.¹⁶
