W-2 and WH-3 Electronic Filing FAQs

What do I need to tell purchasers of my software preparation package about my substitute WH-3s?

Effective July 1, 2010, any employer that files more than 25 W-2s in a calendar year is required to file the WH-3 and their wage statements electronically. This new law (IC 6-3-4-16.5) applies to W-2s filed after Dec. 31, 2010.

What do we as a software developer need to do to help our customers electronically file their W-2s and WH-3s?
