Macroeconomic Analysis of the Tax Cuts And Jobs Act

Abstract

The Tax Policy Center has released an analysis of the macroeconomic effects of the Tax Cuts and Jobs Act as passed by Congress. We find the legislation would boost US gross domestic product (GDP) 0.8 percent in 2018 and would have little effect on GDP in 2027 or 2037. The resulting increase in taxable incomes would reduce the revenue loss arising from the legislation by $186 billion from 2018 to 2027 (around 13 percent). Because most of the individual provisions expire after 2025, we expect deficits (not including interest costs) would decline by $415 billion from 2028 to 2037, and macroeconomic feedback would boost the deficit savings by $3 billion over that interval. Including macroeconomic effects and interest costs, the legislation is projected to increase debt as a share of GDP over 5 percentage points in 2027 to 97 percent of GDP, and almost 4 percentage points in 2037 to 117 percent of GDP.
