WASHINGTON — A computer breach at the IRS in which thieves stole tax information from thousands of taxpayers is much bigger than the agency originally disclosed.
An additional 220,000 potential victims had information stolen from an IRS website as part of a sophisticated scheme to use stolen identities to claim fraudulent tax refunds, the IRS said Monday. The revelation more than doubles the total number of potential victims, to 334,000.
The breach also started earlier than investigators initially thought. The tax agency first disclosed the breach in May.
