how do i know what w2 forms to use

In order to know what W2 forms to use it may be helpful to purchase a W2 form printing software. This can be helpful in guiding you to the correct forms. W2 printing software will generate the entire W2 form including the directions and lets the user know which copy belongs to whom. You may also contact the IRS at www.irs.gov for information on which copies of the W2 form to use.
