The current 20 percent deduction reduces the top marginal tax rate on pass-through business income to 29.6 percent. Although C corporations face a 21 percent corporate tax rate, their profits are also subject to the individual income tax when distributed to shareholders. After considering various tax provisions that reduce the tax burden on C corporation shareholders, the Congressional Budget Office (CBO) finds that pass-through business investment faces a lower tax burden than C corporate investment. After the passage of the OBBBA, lawmakers now have time to plan the next business tax reform. Such a reform should tax business income neutrally and eliminate this deduction.
