Harris proposes raising the corporate tax rate to 28%, rolling back a Trump law

Vice President Kamala Harris is calling for raising the corporate tax rate to 28%, her first major proposal to raise revenues and finance expensive plans she wants to pursue as president.

Harris campaign spokesman James Singer told NBC News that she would push for a 28% corporate tax rate, calling it "a fiscally responsible way to put money back in the pockets of working people and ensure billionaires and big corporations pay their fair share."

"As President, Kamala Harris will focus on creating an opportunity economy for the middle class that advances their economic security, stability, and dignity," Singer wrote in an email.

If enacted, the policy would raise hundreds of billions of dollars, as the nonpartisan Congressional Budget Office has projected that 1 percentage point increases in the corporate rate corresponds to about $100 billion over a decade. It would also roll back a big part of former President Donald Trump's signature legislation in 2017 as president, which slashed the corporate tax rate from 35% to 21%.

Trump, meanwhile, recently said he would cut taxes even further if elected president, including on businesses.

The move comes as Harris slowly adds details to her governing vision on the week of the Democratic convention, including conveying to critics how she would seek to pay for costly ideas, such as expanding the child tax credit and easing the cost of housing and medical debt. She has not provided a cost estimate of her proposals so far or matched them with pay-fors.
