Tax preparer Jackson Hewitt has launched an online Discount Shopping Network that offers cash back rewards from more than 800 retailers, including Target, Sears, Kmart, Best Buy and Staples.

The Discount Shopping Network is part of the first phase of the company’s roll-out of “MyTaxManager,” a new online tax management tool.

By visiting MyTaxManger and clicking on the “My Rewards” tab, users can earn cash back rewards on apparel, sporting goods, electronics, office products, and gourmet foods.

To promote the launch select retailers are offering increased cash back rewards for shopping completed through December 24.

In addition, users who visit MyTaxManger and register will be entered in the Jackson Hewitt Sweepstakes for the chance to win one $100 Visa gift card every day through April 15, 2011, as well as the overall grand prize of $10,000.

"This new shopping network is going to make a real difference for families this holiday season and throughout the year in terms of easy online access, outstanding deals and valuable cash back rewards," said Debra K. Dowd, senior vice president and chief marketing officer of Jackson Hewitt Tax Service Inc.

"And once MyTaxManager is fully launched prior to the opening of tax season, taxpayers will have free access to a one-stop destination to store and organize tax information throughout the year.”
