From the introduction:
The Tax Cuts and Jobs Act, which was introduced on November 2 in the House of Representatives, would raise taxes on some Americans and cut taxes on others while also providing significant savings to foreign investors. Of those tax cuts that would benefit Americans, nearly a third would go to the richest one percent in 2018, and by 2027 that fraction would rise to nearly half. Because the legislation, which will be simply called the House bill in this report, includes provisions that raise taxes and provisions that cut taxes, the net effect for any particular family depends on their situation. This report includes estimates of the House bill’s average impact on each income group and estimates of the fraction of each income group facing a tax cut or a tax hike. The estimates incorporate all the significant changes that the bill would make to the federal personal income tax, corporate income tax and estate tax, as explained in more detail in the methodology section. (See Table 1 and Table 2 for a detailed distributional analysis of the House Bill in 2018 and 2027.)
Some of the provisions in the House bill that benefit the middle-class — like lower tax rates and fewer brackets, an increased standard deduction, and a $300 tax credit for each adult in a household — are designed to expire or become less generous over time. Some of the provisions that benefit the wealthy, such as the reduction and eventual repeal of the estate tax, become more generous over time. The result is that by 2027, the benefits of the House bill become increasingly generous for the richest one percent compared to other income groups…..
