Lessons From 4 States That Boosted Tax Equity
Lawmakers seeking fair tax systems based on the ability to pay have many options.
While many state lawmakers have spent the past few years debating deep and damaging tax cuts that disproportionately help the rich, more forward-thinking lawmakers have improved tax equity by raising new revenue from the well-off and creating or expanding refundable tax credits for low- and moderate-income families.
Many of these positive developments are quantified in the appendices of the Institute on Taxation and Economic Policy’s (ITEP) recent Who Pays? report, where we created alternative analyses to show the distribution of a state’s tax system before and after certain policy changes.
As the transformations below illustrate, upside-down state and local tax codes are not a given. Lawmakers seeking equitable tax systems based on the ability to pay have many options.
New Mexico

Tax changes made in New Mexico since 2018 led the state to jump 18 spots in ITEP’s Tax Inequality Index to the No. 9 least regressive tax code, the biggest positive change of all the states. These policy changes included the expansion of low-income credits like the Earned Income Tax Credit, the creation of a new Child Tax Credit, and tax increases on investment income and high-earning residents. Without those and other changes made since 2018, New Mexico would currently have the 25th most regressive tax system in the country.
Massachusetts

Tax changes made in Massachusetts since 2022 led the state to jump nine spots in ITEP’s Tax Inequality Index to the No. 8 least regressive tax system. These policy changes included 2022 voter approval of the Fair Share Amendment, which created a 4% surcharge on income over $1 million to fund education and transportation projects, as well as legislation in 2023 that among other things, bolstered the state’s refundable credits (which improved equity) and cut estate and capital gains taxes (which detracted from equity but not enough to erase the impact of the other equity-increasing policies). Without all these changes, Massachusetts would currently have the 35th most regressive tax code in the country.
Minnesota

Minnesota was already a national leader on tax fairness. But tax changes made in Minnesota since 2018 led the state to rise three spots in ITEP’s Tax Inequality Index to the No. 2 least regressive tax code, behind only Washington, D.C. These policy changes included the creation of a new, robust Child Tax Credit coupled with tax increases on high investment incomes and some corporations. Without these and other changes made since 2018, Minnesota would currently have the No. 5 least regressive tax system in the country.
Washington

Washington had long been home to the most regressive tax code in the nation due to its lack of an income tax and heavy reliance on sales and excise taxes. But changes made by state lawmakers in the past few years helped Washington shed that dubious distinction and rise one spot on ITEP’s Tax Inequality Index. The state now has the No. 2 most regressive tax system in the country. The small but important move up the rankings was driven by two policy changes: the creation of the state’s Working Families Tax Credit, which functions much like an Earned Income Tax Credit, and the creation of a new Capital Gains Excise Tax.
FINAL DAY! This is urgent.
Dear Common Dreams reader, It’s been nearly 30 years since I co-founded Common Dreams with my late wife, Lina Newhouser. We had the radical notion that journalism should serve the public good, not corporate profits. It was clear to us from the outset what it would take to build such a project. No paid advertisements. No corporate sponsors. No millionaire publisher telling us what to think or do. Many people said we wouldn't last a year, but we proved those doubters wrong. Together with a tremendous team of journalists and dedicated staff, we built an independent media outlet free from the constraints of profits and corporate control. Our mission from the outset was simple. To inform. To inspire. To ignite change for the common good. Building Common Dreams was not easy. Our survival was never guaranteed. When you take on the most powerful forces—Wall Street greed, fossil fuel industry destruction, Big Tech lobbyists, and uber-rich oligarchs who have spent billions upon billions rigging the economy and democracy in their favor—the only bulwark you have is supporters who believe in your work. But here’s the urgent message from me today. It’s never been this bad out there. And it’s never been this hard to keep us going. At the very moment Common Dreams is most needed and doing some of its best and most important work, the threats we face are intensifying. Right now, with just hours left in our Spring Campaign, we're still falling short of our make-or-break goal. When everyone does the little they can afford, we are strong. But if that support retreats or dries up, so do we. Can you make a gift right now to make sure Common Dreams not only survives but thrives? There is no backup plan or rainy day fund. There is only you. —Craig Brown, Co-founder |
