A tax increase for the middle class will not be a part of a multi-trillion dollar infrastructure bill that is expected to be introduced by the Biden Administration this week.

The bill is part of a package of two bills that would cost roughly $3 trillion to $4 trillion dollars on infrastructure and the climate. The theory is that the White House has split these proposals in two because they expect to a lot of push back on Capitol Hill on the climate portion.

Transportation Secretary Pete Buttgieg, the former Mayor of South Bend, had floated the possibility of a mileage tax to help fund the bill in the last few weeks, but he told CNN that will not be the case.

“No, that is not apart of the conversation about this infrastructure bill,” he said. “But, you will be hearing more details in the coming days on how we envision being able to fund this.”

Buttigieg would not elaborate on any of the details that are being discussed on how to pay for the bill, which is being asked for by the White House just weeks after a $3 trillion COVID relief bill passed Congress and was signed into law.

Buttigieg said the infrastructure bill is much needed.

“These are carefully thought through, responsible ideas, that ultimately are going to be a win for the economy and need to be compared to the unavoidability of the status quo,” Buttigieg said.

He also reiterated that households making less than $400,000 a year will not see an extra tax to help pay for the bill.
