The tax law enacted by Republicans at the end of 2017 capped the federal deduction for state and local taxes. Democrats, especially from high-tax states, want to lift the cap. Who would benefit? Based on the same methods Democrats usually use to judge the distribution of tax cuts, the answer is: Households that make more than a million dollars a year would get most of the benefit.
A Bloomberg account continues, “The benefit is largely concentrated among top-earning households, according to the Joint Committee on Taxation’s figures. About 94% of the breaks generated from repealing the cap would be claimed by taxpayers with at least $200,000 in income, according to the data.”
