Tax fraud action

The U.S. government took action in January against 389 people suspected of committing tax fraud through identity theft, the Internal Revenue Service said.

The enforcement efforts, which the IRS said included 109 arrests and 189 indictments, came on the eve of the tax filing season that began Jan. 30 and continues through April 15.

The IRS and the Justice Department have been trying to fight an increase in the crime over the past several years.

Car and truck talk

• Toyota reworked the styling and marketing strategy of its full-size Tundra pickup, seeking increased high-end truck sales after falling short of an earlier goal of boosting work truck deliveries.

The 2014 Tundra will go on sale in September with a revised exterior and interior, quieter cabin and smoother ride, Toyota said Thursday at the Chicago Auto Show.

A new version called the 1794 Edition will give the Tundra two luxury variations, including a reworked Platinum model that now costs more than $48,000 with options.

• General Motors, dueling with Volkswagen to be the world’s second-best-selling automaker, behind Toyota, introduced a diesel Chevrolet Cruze to go against VW’s Jetta in the U.S.

Internet gambling veto

Gov. Chris Christie has vetoed a bill that would have made New Jersey the third state to legalize gambling over the Internet, but he said he would sign it if it had a 10-year time limit and a higher tax rate on casinos.

It was the second time since 2011 that the Republican governor has vetoed an Internet gambling bill passed by the New Jersey Legislature.

Nevada and Delaware have passed laws legalizing Internet betting, which also is happening offshore, untaxed and unregulated.

T-Mobile tests

T-Mobile USA, the fourth-largest U.S. mobile service provider, said that its tests of the new BlackBerry Z10 are going well and that it is aiming to be the first American carrier “out of the gate” with the phone next month.

“The device is more stable than we anticipated,” said Frank Sickinger, head of business sales at T-Mobile USA. “If we are able to speed up the launch date, we will do that. Right now it’s looking like mid-March.”
