IRS 20-Factor Test, California ABC Test, SS-8 Filing, and Recovering Back Taxes
The IRS historically used a 20-factor test to determine whether a worker is an employee or independent contractor. These factors examine the degree of control and independence in the working relationship. Key factors include:
The IRS has since consolidated these into three main categories: behavioral control, financial control, and the type of relationship. No single factor is determinative; the IRS looks at the entire relationship.
California's ABC test, codified by Assembly Bill 5 (AB 5), presumes all workers are employees unless the hiring entity can prove all three of the following conditions:
All three prongs must be satisfied for the worker to be classified as an independent contractor. The B prong is often the most difficult to satisfy, as it requires the work to be truly outside the company's core business. Certain professions have exemptions and use the older Borello test instead.
When misclassified as a 1099 independent contractor instead of an employee, you lose significant legal protections and benefits. These include:
If you believe you have been misclassified, you may be able to recover these lost wages and benefits through a misclassification claim.
To request an official determination of your worker status from the IRS, file Form SS-8, Determination of Worker Status for Purposes of Federal Employment Taxes and Income Tax Withholding. You can file this form if you are a worker who believes you have been misclassified, or if you are a business seeking clarification on how to classify a worker.
The form asks detailed questions about the working relationship, including instructions given, training provided, work schedule, payment methods, and who provides tools and materials. Submit the completed form to the IRS by mail. Processing typically takes at least six months.
The IRS will issue a determination letter stating whether the worker should be classified as an employee or independent contractor. This determination is binding on the employer for federal tax purposes and can support claims for back taxes and other remedies.
Yes, if you were misclassified as an independent contractor, you may be able to recover a portion of the self-employment taxes you paid that should have been your employer's responsibility. As a misclassified worker, you paid the full 15.3% self-employment tax (Social Security and Medicare) instead of the 7.65% employee share.
You can file Form 8919, Uncollected Social Security and Medicare Tax on Wages, to report your wages and pay only the employee share of these taxes. To use this form, you need a reason code, such as having filed an SS-8 or receiving a determination from the IRS or state agency.
You can also file Form 4852, Substitute for Form W-2, if your employer did not provide a W-2. Consult with a tax professional, as incorrectly filing these forms can trigger audits.
The statute of limitations for misclassification claims varies depending on the type of claim and jurisdiction:
It is important to act promptly to preserve your rights and maximize your potential recovery.
In a successful worker misclassification lawsuit, you may recover various types of damages depending on your claims. These can include:
The total recovery can be substantial, especially for long-term misclassification.
To prove misclassification, gather evidence showing the employer controlled how, when, and where you performed your work, or that you fail to meet the legal tests for independent contractor status. Important evidence includes:
California uses two different tests for worker classification depending on the circumstances:
The ABC test, adopted by AB 5, is the default standard and presumes workers are employees unless all three prongs are met. It is considered more worker-friendly because employers must prove all elements.
The Borello test, from the 1989 California Supreme Court case S.G. Borello & Sons v. Department of Industrial Relations, is a multi-factor balancing test that examines the totality of the circumstances, with the primary factor being the right to control the manner and means of accomplishing the work.
Under AB 5, certain professional categories are exempt from the ABC test and instead use the Borello test, including licensed professionals like doctors, lawyers, and accountants; certain creative professionals; and business-to-business contractors meeting specific criteria. Check the current exemption list to determine which test applies to your situation.
