Form SS-8 is an IRS form used to request a formal determination of whether a worker should be treated as an employee or an independent contractor for federal tax purposes. Both firms and workers can file Form SS-8 when there is uncertainty or disagreement about a worker’s classification. The IRS says the form is used to request a determination of worker status for purposes of federal employment taxes and income tax withholding.

Form SS-8 matters in contingent workforces because it can expose whether the company has a consistent process for deciding who should be a W-2 employee, who can properly operate as a 1099 independent contractor, and when a third-party employment model such as an Employer of Record may be a cleaner option.
A worker can file Form SS-8 because they believe they were treated like an employee but paid like a contractor. For example, they may have had a set schedule, reported to a manager, used company equipment, worked exclusively for one company, or performed work that was similar to the company’s regular employees.
Form SS-8 can be filed by either the worker or the firm. That means an employer does not have to initiate the process. A contractor who feels misclassified can file the form directly with the IRS. A business may believe its contractor arrangement is low risk, but if the worker disagrees, Form SS-8 gives that worker a formal path to ask the IRS to review the worker classification and can trigger a review of the company’s broader contingent workforce controls. A Form SS-8 filing does not automatically mean a company will face a full audit. However, it can surface facts that make the company’s classification practices harder to defend, especially if the same contractor model has been used repeatedly across departments or locations.
Misclassification risk is common in fast-growing companies, recently funded startups, project-heavy organizations, and enterprise teams with low HR headcount because a company’s hiring needs move faster than its compliance infrastructure. A department may need specialized workers quickly, so it brings in contractors before fully evaluating whether those workers should be independent contractors, temporary employees, agency workers, or employees of record.
