How does the IRS determine if a worker is an employee or contractor?

The IRS uses a behavioral control, financial control, and relationship-type test. Key factors include whether the business controls how the work is done, whether the worker can work for multiple clients, and whether there is a written contract. Misclassification can result in significant penalties.

Do I need to file a 1099 for a contractor?

Yes. If you pay a contractor $600 or more during the tax year for services, you must file Form 1099-NEC with the IRS and provide a copy to the contractor by January 31. This applies to unincorporated contractors (individuals, sole proprietors, LLCs not taxed as corporations).

What should a US contractor agreement include?

A solid US contractor agreement should define: scope of work, payment terms, independent contractor status, IP ownership (work-for-hire or assignment), confidentiality obligations, non-solicitation (if needed), termination conditions, and dispute resolution/governing state law.

Fill in the details to generate your contractor agreement

Copied to clipboard

An independent contractor agreement defines the relationship between a business and someone who performs work but is not an employee. The distinction matters for tax purposes, benefits, and legal liability.

Use a contractor agreement when:

The worker controls how and when they complete the work
The engagement is project-based or has a defined scope
The worker provides their own tools, equipment, or workspace
The worker serves multiple clients and operates their own business
You are not providing benefits such as health insurance, paid leave, or retirement plans

Use an employment contract instead when:

You control the worker's schedule, methods, and work location
The role is ongoing and integral to your core business
You provide tools, training, and supervision
The worker receives benefits and you withhold payroll taxes

IRS classification risks:

The IRS uses a multi-factor test to determine worker classification. Misclassifying an employee as a contractor can result in back taxes, penalties, and interest.
Key factors include behavioral control (do you direct how work is done?), financial control (does the worker have unreimbursed expenses, opportunity for profit or loss?), and the type of relationship (written contracts, benefits, permanency).
States like California use the stricter ABC test under AB5, which presumes a worker is an employee unless the hiring entity proves otherwise.

Tip: A well-drafted contractor agreement supports your classification by documenting the contractor's independence, but it alone does not determine worker status. The actual working relationship must match the terms of the agreement.

What This Contractor Agreement Generator Creates

This tool generates an Independent Contractor Agreement for US businesses and freelancers, structured to satisfy IRS worker classification tests and transfer intellectual property rights correctly under federal copyright law. A written contractor agreement is the most important document for establishing that a working relationship is a genuine independent contractor arrangement — not an employment relationship subject to payroll taxes, benefits, and labour law protections.

Your generated agreement will include: scope of services and deliverables, payment terms and 1099-NEC reporting confirmation, IP ownership via both work-for-hire clause (17 U.S.C. § 101) and assignment clause (covering code and creative work that may not qualify as work-for-hire), confidentiality obligations, contractor status confirmation (no benefits, no withholding, no workers' compensation), non-solicitation provisions, termination clauses, and governing state law.

IRS classification risk: The IRS uses a 20-factor common law test and the Economic Reality Test to determine whether a worker is an employee or contractor. Misclassification can result in back payroll taxes, penalties, and interest. A clearly written agreement showing the contractor controls how they work, uses their own tools, and can work for multiple clients is a key factor in demonstrating true contractor status.
