How the New Federal Tax Law Affects State Tax Codes

As state legislative sessions swing into high gear, the recently enacted Tax Cuts and Jobs Act (TCJA) is figuring prominently in policy discussions, with officials examining how the bill affects their states and weighing the necessary policy responses.

The 35 Percent Corporate Tax Myth

Before the recent tax law passed, profitable corporations were subject to a 35 percent federal income tax rate on their U.S. profits. Although lobbyists complained about this rate for years, this report (which examines eight years of corporate data) reveals many profitable corporations exploited loopholes and paid no where near the official corporate tax rate.

Corporations Stand to Reap at Least $413 Billion or More in Tax Breaks from New Tax Law

Under the new law,  corporations' accumulated offshore earnings will be taxed at a rate of 15.5 percent and all other offshore earnings at a rate of 8 percent. This change gives corporations a more than $413 billion tax break on the trillions they were sheltering offshore.

State and Local Tax Contributions of Young Undocumented Immigrants

Who Pays? 5th Edition

ITEP's Who Pays? report assesses the fairness of state and local tax systems, examining the share of income paid in state and local taxes by people across the economic spectrum. The new federal tax law is expected to effect changes in many state tax codes this year. ITEP staff continues to monitor and analyze tax policy in all 50 states and plans to update this report in late 2018.

Expert's View

The truth is, if lawmakers truly wanted to craft a tax overhaul that would benefit working people most, they would have started from fundamentally different principles and developed policies that would provide true tax relief for all working families while shutting down favorable tax treatment for rich people.
