After President Trump signaled support for suspending the 18-cent federal gas tax, Indiana lawmakers in Washington say discussions are already underway on what a potential plan could look like.

Congressman Andre Carson says key details, including timing and duration, are still being worked out.

“There’s a bipartisan pathway here, we should take it,” Carson said, adding that the timeline and the length of any suspension remain under negotiation.

Rep. Marlin Stutzman said any change would likely start as a short-term move.

“It most likely would start with 30 days,” Stutzman said. “I think it’ll be a short-term situation.”

Stutzman, who sits on the Budget Committee, said lawmakers will also have to weigh how to maintain funding for road and infrastructure projects.

“Repaving and filling potholes and the infrastructure needs that we have that continue to grow because of a strong economy—we want to make sure that we have the funding there to take care of that,” he said.

At the state level, Governor Mike Braun has already suspended Indiana’s gas excise tax and gas sales tax through early June, though extending any relief would likely require a special session of the legislature.

State Rep. Ed DeLaney said any proposal would likely advance, but warned the decision will require careful consideration.
