W2 forms are to be filed with the Social Security Administration. SSA has two methods of filing the forms. Employers can file paper forms or they can electronically file. I found a nice product by searching the internet for W2 Forms or W2 E-Filing. In order to fill out these forms you may want to consider using a W2 filing software. One good software is known as W2 Mate and a demo version of the software can be found on the publisher’s website at www.realtaxtools.com
