Contract work is a self-employed arrangement in which you provide services to a client for a specific project, task, or time period instead of joining a company as a permanent employee. The IRS treats you as a separate business: you receive a Form 1099-NEC rather than a W-2, no taxes are withheld from your pay, and you are responsible for your own income tax, Social Security and Medicare contributions, insurance, and business expenses. The model runs across industries, from technology consulting to creative freelancing to on-demand platform work.
How the IRS Treats a Contract Worker
Under this classification, you operate as a separate business entity and the hiring party is a client, not an employer. The client does not withhold income taxes, Social Security, or Medicare from what it pays you. Instead, any business that pays you $600 or more during a tax year must file a Form 1099-NEC reporting those payments.1Internal Revenue Service. Instructions for Forms 1099-MISC and 1099-NEC Before the work starts, you typically give the client a Form W-9 with the taxpayer identification number they need for that reporting.2Internal Revenue Service. Reporting Payments to Independent Contractors The 1099-NEC itself is defined by the IRS as the form for nonemployee compensation.3Internal Revenue Service. About Form 1099-NEC, Nonemployee Compensation
If clients pay you through third-party platforms like PayPal, Venmo, or a credit card processor, you may also receive a Form 1099-K. Under current law, the processor must issue one when your gross payments through the platform exceed $20,000 and the number of transactions exceeds 200 in a calendar year.4Internal Revenue Service. Form 1099-K FAQs Even without a 1099-K or 1099-NEC, every dollar you earn is still taxable and must be reported.
Common Forms Contract Work Takes
Contract work isn’t one thing. It comes in several shapes, and the shape affects how you find clients, get paid, and manage risk.
- Direct freelancing. A one-on-one agreement between you and a client to deliver a specific output. Common in creative and technical fields where you own the entire relationship.
- Gig-based platform work. Digital platforms match you with short-term tasks. The platform handles the transaction and sometimes sets pricing, though you generally choose which jobs to accept.
- Project-specific consulting. A client hires you for expert advice or to solve a particular business problem within a set timeframe. Consultants often operate through an LLC or sole proprietorship.
- Agency-represented contracting. A staffing or consulting firm acts as an intermediary and sometimes serves as the employer of record. The agency handles payroll and benefits while you perform work for an external client.
What Belongs in Your Contract
A written agreement protects both sides. Terms vary, but most service contracts cover the same core areas.
A statement of work spells out scope and deliverables, so there is no argument mid-project about what’s included in the price. Payment terms set whether you’re paid hourly, by milestone, or at a flat rate, along with the invoice window, commonly 30 or 60 days. Termination clauses describe how either side can end the engagement early, often on 14 to 30 days of written notice. Intellectual property language decides who owns the work product; in many contracts, ownership transfers to the client on final payment. Confidentiality provisions protect sensitive information you see during the engagement.
Am I Really a Contractor or an Employee?
Not every worker labeled a contractor actually qualifies as one. Two overlapping frameworks decide the question, and getting it wrong exposes the hiring business to back taxes, penalties for unpaid payroll contributions, and legal liability.
The IRS Common-Law Test
The IRS looks at three categories. Behavioral control asks whether the business has the right to direct how the work is done; if a company dictates the sequence of tasks or trains you on mandatory methods, that points toward employment.5Internal Revenue Service. Behavioral Control Independent contractors typically choose their own methods, tools, and schedules. Financial control looks at who provides equipment, whether you can earn a profit or take a loss, and whether you offer services to the general public; a contractor who invests in tools, markets to multiple clients, and bears real expense risk is more clearly independent. Relationship type weighs written contracts, benefits like health insurance or paid leave, and how permanent the arrangement is. A defined project supports contractor status; an open-ended engagement invites reclassification.
The DOL Economic Reality Test
The Department of Labor uses a separate six-factor test under the Fair Labor Standards Act, updated by a 2024 final rule. It asks whether you are economically dependent on the hiring entity or truly in business for yourself. The factors are your opportunity for profit or loss, your investments compared with the employer’s, the permanence of the relationship, the nature and degree of control, how integral your work is to the business, and the skill and initiative you bring. No single factor decides the result; the agency weighs all six together.6U.S. Department of Labor. Fact Sheet 13: Employment Relationship Under the Fair Labor Standards Act
A narrow group of workers falls into a hybrid category the IRS calls “statutory employees” (certain delivery drivers, full-time life insurance agents, home workers, and traveling salespeople). They receive a W-2 with a special box checked and report income on Schedule C, so their tax treatment is not the same as a standard 1099 contractor.7Internal Revenue Service. 8Social Security Administration. If You Are Self-Employed9Social Security Administration. Contribution and Benefit Base If your net self-employment income exceeds $200,000 as a single filer or $250,000 filing jointly, an extra 0.9% Medicare tax applies to the amount above that threshold.10Internal Revenue Service. Topic No. 560, Additional Medicare Tax You can deduct half of your self-employment tax when figuring your adjusted gross income.11Internal Revenue Service. Topic No. 554, Self-Employment Tax
Quarterly Estimated Payments
Because nothing is withheld from your pay, you generally have to make estimated tax payments four times a year using Form 1040-ES. For the 2026 tax year, the due dates are April 15, 2026 (January through March income), June 15, 2026 (April through May), September 15, 2026 (June through August), and January 15, 2027 (September through December).
Miss a deadline or underpay and the IRS charges an interest-based penalty at the federal short-term rate plus three percentage points, which was 7% in early 2026.12Internal Revenue Service. Quarterly Interest Rates You generally avoid the penalty by paying at least 90% of your current year’s tax liability or 100% of last year’s tax through estimated payments.13Internal Revenue Service.

Deductions That Lower Your Tax Bill
You report business income and expenses on Schedule C (Form 1040). Deductions come straight off your taxable income, so careful tracking is worth real money.
The home office deduction is available if you use a dedicated space regularly and exclusively for business. The simplified method pays $5 per square foot up to 300 square feet, for a maximum of $1,500 a year.14Internal Revenue Service. Simplified Option for Home Office Deduction The regular method (Form 8829) uses actual costs like rent, utilities, insurance, and repairs multiplied by the business-use percentage of your home, and can beat the simplified amount when your expenses are high.
Vehicle and mileage. Business driving is deductible. For 2026, the IRS standard mileage rate is 72.5 cents per mile for business use.15Internal Revenue Service. 2026 Standard Mileage Rates You can use that rate or track actual costs (gas, maintenance, insurance, depreciation), but you must pick one method per vehicle and keep a mileage log either way.
Health insurance. If you have a net profit and are not eligible for a subsidized employer plan through a spouse or another job, you can deduct 100% of premiums for medical, dental, vision, and qualified long-term care coverage for yourself, your spouse, and your dependents. This deduction goes on Schedule 1 using Form 7206, not on Schedule C.16Internal Revenue Service. Instructions for Form 7206
Qualified business income. The Section 199A deduction lets eligible self-employed workers deduct up to 20% of qualified business income from a sole proprietorship, partnership, or S corporation. It was originally set to expire after 2025 but has been made permanent.17Internal Revenue Service. Qualified Business Income Deduction Income thresholds and phase-outs apply, especially for service businesses, so what you actually get depends on your total taxable income and the type of work you do.
Other common write-offs include software and subscriptions used for the business, professional fees for tax preparation, legal advice, and bookkeeping, 50% of business meals, education and training that maintains or improves skills you already use for work, and equipment. Items over $2,500 with a useful life beyond one year are generally depreciated rather than expensed all at once.
Retirement Savings You Set Up Yourself
There is no employer 401(k) match waiting for you. Two accounts do the heavy lifting for most contractors.
A SEP IRA lets you contribute up to 25% of your net self-employment earnings, with a maximum of $69,000 for 2026.18Internal Revenue Service. SEP Contribution Limits (Including Grandfathered SARSEPs) SEP IRAs are simple to open, have no annual filing requirement, and contributions are deductible. The limitation is that you contribute only as the “employer”; there is no separate employee deferral.
A Solo 401(k) is available if your only employee is a spouse. It allows an employee deferral (up to $24,500 in 2026) plus employer profit-sharing (up to 25% of net self-employment earnings), for a combined maximum of $72,000. Catch-up contributions raise the deferral limit if you are 50 or older. A Roth option lets you make after-tax contributions that grow tax-free.
Insurance You Have to Arrange
You are not covered by any client’s insurance policies, and some clients want proof of coverage before you can start.
- Professional liability (errors and omissions). Protects you if a client claims your work caused them financial harm, such as a coding error that leads to data loss or advice that backfires.
- General liability. Covers property damage or bodily injury claims, which matters most when you work on-site at a client’s location.
- Workers’ compensation. A client’s policy does not cover you. Some states require sole proprietors in certain industries to carry their own coverage, and buying it can be worthwhile whenever your work involves physical risk.
Setting Up Your Business Identity
Running a contracting business, even a one-person one, works better with a few administrative pieces in place.
An Employer Identification Number (EIN) is a free, nine-digit IRS number that identifies your business for tax purposes. Putting it on your W-9 instead of your Social Security number keeps your SSN off client records and reduces identity theft risk. You can apply online for free.
A “doing business as” (DBA) name lets you operate under a business name that differs from your legal name. Registration requirements and fees vary; you may file with a county clerk or state office, and fees are generally under $100.19U.S. Small Business Administration. Register Your Business Some places also require publishing a public notice in a local newspaper after registering.
Forming a limited liability company (LLC) puts a legal wall between your personal assets and your business debts. If a client sues the LLC, your personal savings and property are generally protected. State filing fees range widely, and many states charge annual fees or franchise taxes to keep the entity active. An LLC also affects your taxes: a single-member LLC is taxed as a sole proprietorship by default, but you can elect S corporation treatment if the numbers work out.
