evidence: - Raising the corporate tax rate to 28% and the corporate minimum tax to 21%. President Biden believes large corporations should pay their fair share, and is committed to reversing the massive tax giveaway to big corporations that Republicans enacted in 2017. President Biden would raise the corporate tax rate to 28%. He would also ensure that billion-dollar corporations pay at least 21% of their income in taxes, building on the Inflation Reduction Act’s (IRA) corporate minimum tax. [...] - Quadrupling the stock buyback tax. In response to the surge in corporate stock buybacks after the Trump tax cuts, President Biden signed into law a surcharge on stock buybacks that encourages businesses to invest in their growth and productivity as opposed to funneling tax-preferred profits to wealthy and foreign shareholders. President Biden would quadruple the stock buyback tax from one percent to four percent to address the continued tax advantage for buybacks and encourage corporations to invest in productivity and the broader economy rather than windfalls for investors.
