I. WORKER CLASSIFICATION RULES
A. Present Law
In general

Significant tax consequences result from the classification of a worker as an employee or independent contractor. These consequences relate to withholding and employment tax requirements, as well as the ability to exclude certain types of compensation from income or take tax deductions for certain expenses. Some consequences favor employee status, while others favor independent contractor status. For example, an employee may exclude from gross income employer-provided benefits such as pension, health, and group-term life insurance benefits. On the other hand, an independent contractor can establish his or her own pension plan and deduct contributions to the plan. An independent contractor also has greater ability to deduct work related expenses.

Under present law, the determination of whether a worker is an employee or an independent contractor is generally made under a facts and circumstances test that seeks to determine whether the worker is subject to the control of the service recipient, not only as to the nature of the work performed, but the circumstances under which it is performed. Under a special safe harbor rule (sec. 530 of the Revenue Act of 1978), a service recipient may treat a worker as an independent contractor for employment tax purposes even though the worker is in fact an employee if the service recipient has a reasonable basis for treating the worker as an independent contractor and certain other requirements are met. In some cases, the treatment of a
worker as an employee or independent contractor is specified by statute.
