State Rundown 2/26:  House Budget Plan Could Further Strain State Budgets

States would be wise to keep a close eye on happenings in Washington, D.C. Republicans in the House of Representatives recently passed their budget resolution, which could spell trouble for state budgets. The plan tees up major cuts to Medicaid, SNAP, and college tuition assistance—all likely to allow for tax cuts that will overwhelmingly benefit the wealthy. If approved, trillions of dollars would be cut from programs supported by federal dollars and states and localities could bear the brunt of those shifting costs. Many states are already facing delicate fiscal outlooks and those considering cutting taxes further should seriously reconsider.…

Learn from Prop 13 History to Avoid Repeating Past Mistakes

Worries about housing costs and property tax bills are leading people to check the history books for solutions, but there’s a danger that they’ll repeat past mistakes.

State Rundown 2/20: Tools to Address Corporate Tax Avoidance and Property Tax Affordability

A new ITEP report finds that states could raise $19 billion a year with one policy change targeting corporate tax avoidance. That policy, worldwide combined reporting, strengthens state corporate taxation by giving states a full view of multinational corporate profits, essentially eliminating the tax savings that companies currently see by pretending their profits were earned in Switzerland, the Cayman Islands, and other international tax havens.

Worldwide combined reporting negates the tax benefits of shifting corporate income offshore Public polling has consistently shown for decades that most people believe big multinational corporations are paying too little in taxes. Closing the loopholes these corporations use to avoid taxes is one of the most effective – and popular – solutions to this problem. […]

February 5, 2025 • By Rita Jefferson

Capital & Main: Why Mass Deportations Would Cripple California’s Economy

November 22, 2024

Trump has, after all, already made full-throated declarations that his administration will conduct the largest deportation of undocumented residents in U.S. history.
