Are there tutorials online for filling out a W-2?

Online tutorials are available for filling out a W-2. Intuit offers an interactive infographic that explains how to fill out each box on a W-2 form. There is also a detailed description of each W-2 box and code at About.com.

The W-2 is a form provided by the Internal Revenue Service for employers to report the wages earned by employees and the taxes withheld from those wages. Employers must file a W-2 for any employee paid $600 or more in cash remuneration or other benefits in a year, and provide a W-2 to employees by January 31st of that year, according to the IRS.
