Independent contractors

One of the most common mistakes businesses make when filing their unemployment insurance tax reports each quarter is misclassifying their employees as independent contractors. When we discover these mistakes, the business must pay back taxes for all misclassified workers, plus penalties and interest.

Use the following two tests to help you determine a worker’s status. There is one test specifically for electrical and construction contractors and one for all other industries. If a worker passes one of the following tests, he or she is an independent contractor. If not, he or she is an employee and should be reported on your quarterly unemployment tax report. If you are unsure whether a worker qualifies as an employee, contact your Tax Account Management Center.
