Table shows the effect marginal tax rates on wages and salaries under current law and the Conference Agreement for the Tax Cuts and Jobs Act by Expanded Cash Income Percentile in 2018. We calculate effective marginal tax rates by adding $1,000 to wages and salaries and recomputing tax liability. Our computation includes the impact of the alternative minimum tax and the phase-in and phase-out of credits and other tax provisions. We assume that the increase in wages does not change the reported amount of any deductions, exclusions, or other forms of income. Effective marginal tax rates are weighted by current-law wages and salaries.
