The Internal Revenue Service

Jan. 30, 2013 opened the filing season by announcing a variety of enhanced products and services to help taxpayers prepare and file their tax returns by the April 15 deadline.

New and expanded services for taxpayers this year include a redesigned IRS.gov web site that is easier to navigate and improved service options, including more video-conferencing assistance sites and additional social media tools. In addition, the IRS has stepped up its enforcement efforts to protect taxpayers from refund fraud and identity theft.
