This note uses existing empirical estimates of the macroeconomic effects of tax changes to project the near term impact of the Tax Cuts and Jobs Act on US GDP growth. Applying recent reduced form estimates of tax multipliers with the projected revenue impact of the Act yields a level of GDP that is predicted to be 1.3% higher by 2020, with most of the growth front-loaded in 2018. Accounting for the composition of the Act in terms of its individual and corporate provisions leads to a similar GDP increase by 2020, but with stronger growth in 2018 and a partial reversal in the following years. Accounting for the impact of TCJA on marginal individual tax rates raises the projected growth impact considerably, while accounting for the distribution of the tax changes across income groups suggests a more delayed positive impact on GDP. These projections are conditional on mean-reverting dynamics of future taxes that are estimated from postwar US data.
