In this episode, we break down what the OBBBA did, walk through our projections, and zoom out to other defining fights of 2025: Trump’s “Liberation Day” tariffs, the Supreme Court challenge over presidential tariff power, and the growing wave of property tax revolts across the states.
Several states have decoupled from GILTI by name rather than statutory citation.

The State Tax Competitiveness Index enables policymakers, taxpayers, and business leaders to gauge how their states’ tax systems compare. While there are many ways to show how much state governments collect in taxes, the Index evaluates how well states structure their tax systems and provides a road map for improvement.

When the Kansas City and Los Angeles squads face off in São Paulo, the players will owe Brazil’s nonresident income tax on the share of income they earned there, while California will lose out on the nonresident income taxes that Chiefs players ordinarily would have remitted in what is nominally a Chargers home game.

Congress may have passed the One Big Beautiful Bill Act (OBBBA), but state lawmakers now face big choices. Most states link their tax codes to the federal system, meaning OBBBA’s provisions—good and bad—are about to ripple across state budgets.
For Congress, work on the One Big Beautiful Bill Act is done. But in state capitols, the work has not yet begun. Many of the tax changes in the federal reconciliation act flow through to state tax codes—automatically in some states, and subject to an update in states’ Internal Revenue Code conformity date in others.
