Gov. Mike Braun announced the suspension on April 8.
“I am declaring a gas tax holiday to give Hoosiers relief from the pain at the pump from high gas prices,” Braun said in a statement. “Affordability is my top priority.”
Indiana’s state gas sales tax, also known as its gasoline use tax, is 7 percent. A separate excise tax of $0.36 cents a gallon is not affected by the suspension.
The 30-day reprieve could be extended, Braun’s office said.
