Downloading a W-2 form that can be filled out involves going to the Internal Revenue Service website and searching for the form, according to the IRS. Employers must complete a W-2 form for each of their employees who had Medicare, Social Security or income tax withheld.
Filling out a W-2 form can be done online or by a tax professional, notes Forbes. Once a W-2 form has been filled out, one copy is sent to the IRS, and another is sent to the employee. Employees should make sure the information on their forms is correct. Some tax filing software is free, while others, such as those for self-employed individuals, require payment.
