Update to Is Your Worker Really an Independent Contractor.

Facts that provide evidence of the degree of control and independence fall into three categories:
- Behavioral: Does the company control or have the right to control what the worker does and how the worker does his or her job?
- Financial: Are the business aspects of the worker’s job controlled by the payer? (these include things like how worker is paid, whether expenses are reimbursed, who provides tools/supplies, etc.)
- Type of Relationship: Are there written contracts or employee type benefits (i.e. pension plan, insurance, vacation pay, etc.)? Will the relationship continue and is the work performed a key aspect of the business?
After reviewing the three categories of evidence, if you are still unsure if a worker is an employee or an independent contractor, the business can file Form SS-8, Determination of Worker Status for Purposes of Federal Employment Taxes and Income Tax Withholding (PDF) with the IRS. The form may be filed by either the business or the worker. The IRS will review the facts and circumstances and officially determine the worker’s status.
Be aware that it can take up to six months to get a determination, but a business that continually hires the same types of workers to perform particular services may want to consider filing the Form Form SS-8 (PDF).
