Summary: We analyze several foreign and domestic business taxation provisions from the Biden tax plan. While raising the effective tax rate on foreign profits increases domestic capital, wages, and GDP, provisions that raise domestic business taxes have the opposite effect—when combined, these business tax provisions decrease the capital stock by 0.21 percent and decrease wages by 0.69 percent in 2050.

Foreign Lower the GILTI deduction to 25 percent, raising the effective minimum rate on foreign profits.
