If you believe that you were treated as an independent contractor but should have been treated as an employee, you may be able to file a Form 8919 to recover any uncollected social security and medicare taxes. However, it is important to note that the determination of employee status is a complex legal issue that depends on the specific facts and circumstances of the relationship between the parties. You may want to consult with a tax professional or attorney to help you determine your status and whether you are eligible to file a Form 8919.
