Which corporate tax proposal is associated with Joe Biden's tax plan?

The correct answer reflects the proposal to increase the federal corporate tax rate to 28%, which is part of Joe Biden's broader tax plan aimed at generating additional revenue for infrastructure and social programs. Biden's administration sought to reverse some of the tax cuts implemented in previous years, specifically those enacted under the Tax Cuts and Jobs Act of 2017, which lowered the corporate tax rate to 21%.

By raising the rate to 28%, the intention is to ensure that corporations contribute a fairer share to federal revenues, especially as the government aims to fund various public initiatives. The proposal aligns with the administration's broader priorities of improving economic equity and funding critical public services, highlighting a shift in fiscal policy towards more progressive tax structures.

This contrast with the other choices is significant, as they either propose tax cuts or a different structure that does not align with the direction of Biden's tax plan.
