What is Subcontractor?

An independent individual or company hired by a general contractor to perform specific portions of work on a project.

Definition

A subcontractor is an independent contractor or firm that is hired by a general contractor or project lead to perform specific, defined work on a project. Subcontractors are commonly used in construction, trades, consulting, and professional services. The subcontractor is responsible for their own taxes, insurance, and business registration, and they typically work under a formal subcontract agreement that specifies the scope of work, payment terms, and timeline. The general contractor remains ultimately responsible to the client for the entire project.

Subcontractor vs. Independent Contractor

While the terms are often used interchangeably, there is a subtle distinction: an independent contractor is a broad category of worker who is not an employee. A subcontractor is a specific type of independent contractor who is hired to work on a portion of a larger project under the direction of a general contractor. Not all independent contractors are subcontractors (a freelance writer hired directly by a publisher is an independent contractor but not a subcontractor), but all subcontractors are independent contractors. Both share the common trait of controlling their own work methods and being responsible for their own tax obligations.

Hiring a Subcontractor: Legal Considerations

When hiring subcontractors, general contractors must: verify the subcontractor's business status (EIN, business license, insurance coverage); obtain a signed W-9 form before making payments; execute a written subcontract agreement that covers scope of work, deliverables, payment schedule, timeline, insurance requirements, and indemnification clauses; confirm the subcontractor has adequate liability insurance and workers' compensation coverage (if required in your state); and file 1099-NEC forms for payments of $600 or more per year. Misclassifying a subcontractor as an independent contractor when they should be classified as an employee can result in back taxes, penalties, and legal liability.

Subcontractor Agreements

A solid subcontractor agreement should include: full names and business information of both parties; a detailed description of the scope of work and deliverables; the project timeline with key milestones; the payment amount and schedule (including when final payment is made); provisions for change orders if the scope changes; requirements for permits, licenses, and insurance; confidentiality clauses to protect client information; warranties on the quality of work; procedures for handling disputes; and provisions for termination if either party fails to meet their obligations.

Tax Obligations When Using Subcontractors

General contractors who hire subcontractors have specific tax reporting obligations: file Form 1099-NEC for each subcontractor paid $600 or more in a calendar year; report subcontractor payments on Form 1099-MISC if part of the payment is not 1099-NEC reportable; withhold and pay backup withholding if the subcontractor fails to provide a valid TIN; and note that payments to subcontractors are not subject to federal unemployment tax (FUTA) or Social Security/Medicare withholding because subcontractors are not employees. Subcontractors are responsible for paying their own self-employment tax and income tax on their earnings.

Frequently Asked Questions

What is a subcontractor?

A subcontractor is an independent individual or business hired by a primary contractor (also called a general contractor) to perform a specific portion of work on a project. The subcontractor is typically hired for their specialized skills or to handle portions of a project that the general contractor does not have the capacity or expertise to complete themselves. Unlike an employee, a subcontractor generally controls how and when the work is performed.

Do I need to issue a 1099 to a subcontractor?

If you pay a subcontractor $600 or more in a calendar year for services rendered, you are generally required to file IRS Form 1099-NEC (Nonemployee Compensation) to report the payment. You will need the subcontractor's Social Security Number (SSN) or Employer Identification Number (EIN) and their completed Form W-9 before making payments. Failure to file required 1099s can result in IRS penalties.

What is the difference between an employee and a subcontractor?

The key distinction is behavioral and financial control: an employee works under the direction and control of the employer, following set schedules and methods. A subcontractor works independently, controls their own methods and schedule, typically works for multiple clients simultaneously, and is paid per project or deliverable rather than per hour. The IRS uses a three-factor test (behavioral control, financial control, and relationship type) to determine worker classification. Misclassifying employees as subcontractors can result in significant tax penalties and liability.
