What Form Do Contract Workers Fill Out?

Contract workers are becoming more and more common in today`s workforce. They offer a flexible solution for businesses that require additional staffing during peak periods or for specific projects. However, hiring contract workers can be confusing, particularly when it comes to filling out the necessary paperwork. One of the most important questions businesses ask is: what form do contract workers fill out?

The answer to this question depends on the employment status of the contract worker. In general, contract workers fall into two categories: independent contractors and employees of staffing agencies. The paperwork required for each varies slightly.

Independent Contractors

Independent contractors are self-employed individuals who provide services to businesses on a contract basis. They are responsible for maintaining their own business and paying their taxes. Independent contractors typically fill out a Form W-9, which is a Request for Taxpayer Identification Number and Certification. This form is used by businesses to report payments made to the contractor to the Internal Revenue Service (IRS). The contractor must provide their name, address, and taxpayer identification number (TIN), which is usually their Social Security Number (SSN) or Employer Identification Number (EIN).

Employees of Staffing Agencies

Some businesses hire contract workers through staffing agencies. In this case, the staffing agency is the employer of record, and the contract worker is an employee of the staffing agency. The staffing agency is responsible for withholding taxes and providing benefits for the employee. In this situation, the contract worker will typically fill out a Form W-4, which is an Employee`s Withholding Certificate. This form is used by the employer of record to determine how much federal income tax to withhold from the employee`s paycheck. The employee must provide their name, address, and Social Security Number, as well as their filing status and the number of allowances they are claiming.


Hiring contract workers can be a great way for businesses to meet their staffing needs. However, it is important to understand the paperwork required for each type of contract worker. Independent contractors typically fill out a Form W-9, while employees of staffing agencies fill out a Form W-4. By understanding the paperwork required, businesses can ensure that they are in compliance with tax laws and regulations.
