TaxAct - Tax Act Online

TaxAct is an American tax preparation software package. It is a member of the Free File Alliance, a free federal tax preparation and electronic filing program for eligible individual taxpayers developed through a partnership between the IRS and a group of private sector tax software companies.

In October 2010, H&R Block said it would pay $287.5 million in cash to acquire the parent firm of TaxAct. In May 2011 the U.S. Department of Justice attempted to stop the acquisition in an antitrust lawsuit. In November 2011, a federal judge sided with the Justice Department, and both companies mutually terminated the contract.

Blucora, then Infospace, acquired TaxAct in January 2012.
