WASHINGTON – President Joe Biden on Monday defended his proposal to raise corporate taxes to help pay for his infrastructure spending plans, saying he was not worried the hike would harm the economy and that there was no evidence it would drive business abroad.

Speaking to reporters in Washington after spending Easter weekend at the Camp David presidential retreat in Maryland, Biden again took aim at the 50 or 51 corporations on the Fortune 500 list that paid no taxes at all for three years, saying it was time for them to pay their share.

Asked if raising the corporate tax rate to 28% from 21% would drive away corporations, Biden said: “Not at all … there’s no evidence of that.”

Biden’s predecessor, Donald Trump, and Republican lawmakers cut the corporate rate to 21% in 2017 from 35%. Trump repeatedly promised to tackle the nation’s crumbling infrastructure during his presidency but never delivered on that.

Biden’s plans have drawn criticism from both Republicans and Democrats, including Democratic Senator Joe Manchin, whose support could be critical to ensuring passage in a Senate split evenly between the two parties.

White House press secretary Jen Psaki told reporters the Democratic president was open to discussions with Republicans and Democrats about how to fund the proposed investments.

Asked if the administration had analyzed the cost of agreeing to a lower corporate tax rate of 25%, the highest Manchin says he would accept, Psaki noted the 28% rate would be lower than it was at any time since World War Two.

“Combined with the other tax proposals, it would pay for the totality of the package. That’s why he felt it was a responsible proposal to make,” Psaki said of Biden.

“There will be different ideas for pay-fors, there will be different ideas for tax proposals. That will all need to be weighed … with leaders in Congress.”
