Advantaging Affluence: A Distributional Analysis of Missouri HB 798’s Uneven Tax Cuts for Wealth and Work
March 28, 2025 • By Aidan Davis, Carl Davis, Dylan Grundman O'Neill, Eli Byerly-Duke, Matthew Gardner
Missouri House Bill 798 would reduce personal and corporate income tax rates, fully eliminate taxes on capital gains income from sale of assets, and eliminates the state’s modest Earned Income Tax Credit that assists many working people in lower-paid jobs. HB 798 would radically transform Missouri’s income tax code into a system that privileges income from wealth over income from work, leaving many middle-income families to pay a higher income tax rate than wealthy people living off their investments.

March 11, 2025 • By ITEP Staff

Corporate Income Tax Filing Methods: States with Water’s Edge or Worldwide Combined Reporting
February 21, 2025 • By ITEP Staff
The purpose of state corporate income taxes is to tax the profit, or net income, an incorporated business earns in each state.

Twenty-eight states plus D.C. now require a limited version of combined reporting called “water’s edge” […]

Louisiana Lawmakers Pass Deeply Regressive Tax Plan
November 26, 2024 • By Neva Butkus
Louisiana Gov. Jeff Landry called the legislature back to the capitol the day after the national election to take up his plan to overhaul the state’s tax system during a 20-day special session. Our analysis shows the tax overhaul would worsen the inequity already rampant in Louisiana’s tax system while potentially shortchanging essential services for families across the state.

Major tax cuts were largely rejected this year, but states continue to chip away at income taxes. And while property tax cuts were a hot topic across the country, many states failed to deliver effective solutions to affordability issues.
Five Things to Know About Tax Foundation’s Critique of Maryland’s Worldwide Combined Reporting Proposal
April 1, 2024 • By Carl Davis, Matthew Gardner
Maryland lawmakers are considering enacting worldwide combined reporting (WWCR), also known as complete reporting. This policy offers a more accurate, and less gameable, way to calculate the amount of profit subject to state corporate tax. Enacting WWCR in Maryland would represent a huge step toward eliminating state corporate tax avoidance as it neutralizes a wide […]

March 20, 2024 • By Marco Guzman, Miles Trinidad
These forward-thinking states are demonstrating the wide variety of options for policymakers who want to raise more from the wealthiest people, rein in corporate tax avoidance, create fair tax codes and build strong communities.
State Tax Watch 2024
January 23, 2024 • By ITEP Staff
Updated July 15, 2024 In 2024, state lawmakers have a choice: advance tax policy that improves equity and helps communities thrive, or push tax policies that disproportionately benefit the wealthy, drain funding for critical public services, and make it harder for low-income and working families to get ahead. Despite worsening state fiscal conditions, we expect […]
Far From Radical: State Corporate Income Taxes Already Often Look Beyond the Water’s Edge
November 7, 2023 • By Carl Davis, Matthew Gardner
State lawmakers are increasingly interested in reforming their corporate tax bases to start from a comprehensive measure of worldwide profit. This provides a more accurate, and less gameable, starting point for calculating profits subject to state corporate tax. Mandating this kind of filing system, known as worldwide combined reporting (WWCR), would be transformative, as it would all but eliminate state corporate tax avoidance done through the artificial shifting of profits into low-tax countries.
The Highs and Lows of 2023 State Legislative Sessions
July 7, 2023 • By Aidan Davis
Nearly one-third of states took steps to improve their tax systems this year by investing in people through refundable tax credits, and in a few notable cases by raising revenue from those most able to pay. But another third of states lost ground, continuing a trend of permanent tax cuts that overwhelmingly benefit high-income households and make tax codes less adequate and equitable.
Minnesota’s Tax Battle of 2023 Signals a Turning of the Tide Against Corporate Tax Avoidance
July 7, 2023 • By Matthew Gardner
The qualified success of Minnesota’s GILTI conformity—to say nothing of the state’s serious dalliance with the game-changing worldwide combined reporting--sends a clear signal that the days may be coming to an end when big multinationals can scare state lawmakers into allowing them to game the tax system.
Minnesota Poised to Enact Landmark Loophole-Closing Corporate Tax Reforms
May 7, 2023 • By Matthew Gardner

Minnesota Lawmakers Re-Envision State Tax System to Center Equity
May 3, 2023 • By Neva Butkus
Minnesota’s House, Senate and Governor’s office have each proposed their own vision as to how the state should maximize its $17.5 billion surplus and raise new revenue, and these tax plans make one thing clear: Minnesota lawmakers are serious about using tax policy to advance tax equity and improve the lives of Minnesotans.
New Jersey, New York, and Connecticut Should Keep Corporate Taxes Strong, Extend Surcharges
February 28, 2023 • By Marco Guzman
At a time when corporations are seeing record profits while not paying their fair share of federal taxes, state corporate income taxes can and should play a role in raising sustainable revenue and adding progressivity to state tax codes. Right now, lawmakers in New Jersey, New York, and Connecticut have a unique opportunity to extend targeted tax changes that have raised billions of dollars from profitable corporations for meaningful public investments.
The Five Best Tax Ideas Coming from Governors This Year
February 22, 2023 • By Carl Davis
The word “tax” appears 97 times and counting in one recent summary of governors’ addresses to state legislators so far this year. The policy visions that governors are bringing, however, vary enormously. While there's good reason to worry about tax cuts for wealthy families and the flattening or elimination of income taxes, there are at least five great tax ideas coming directly out of governors’ offices this year.
Tax Foundation’s ‘State Business Tax Climate Index’ Bears Little Connection to Business Reality
October 31, 2022 • By Carl Davis, Matthew Gardner
The big problem with the Index is that it peddles a solution that not only falls short of the goal of generating business investment, but one that actively harms state lawmakers’ ability to provide the kinds of public goods – like good schools and modern, efficient transportation networks – that businesses need and want.
A Simple Fix for a $17 Billion Loophole: How States Can Reclaim Revenue Lost to Tax Havens
January 17, 2019 • By Richard Phillips
Enacting Worldwide Combined Reporting or Complete Reporting in all states, this report calculates, would increase state tax revenue by $17.04 billion dollars. Of that total, $2.85 billion would be raised through domestic Combined Reporting improvements, and $14.19 billion would be raised by addressing offshore tax dodging (see Table 1). Enacting Combined Reporting and including known tax havens would result in $7.75 billion in annual tax revenue, $4.9 billion from income booked offshore.
How States Can Help Shut Down Tax Havens by Cracking Down on Profit Shifting
January 17, 2019 • By Richard Phillips
A core problem with our corporate income tax laws at the federal and state levels is that they allow companies to use accounting gimmicks to shift significant amounts of their profits into low or zero-tax jurisdictions. Federal lawmakers had an opportunity to address this with the 2017 tax law, but they failed to do so, and, in fact, the law may incentivize more offshore tax avoidance. State lawmakers, however, can buck the federal trend and crack down on profit shifting themselves.

New Report Finds that Upside-down State and Local Tax Systems Persist, Contributing to Inequality in Most States
October 17, 2018 • By Aidan Davis
State and local tax systems in 45 states worsen income inequality by making incomes more unequal after taxes. The worst among these are identified in ITEP’s Terrible 10. Washington, Texas, Florida, South Dakota, Nevada, Tennessee, Pennsylvania, Illinois, Oklahoma, and Wyoming hold the dubious honor of having the most regressive state and local tax systems in the nation. These states ask far more of their lower- and middle-income residents than of their wealthiest taxpayers.
