Ten years ago, then-Speaker Paul Ryan and Ways and Means Chairman Kevin Brady released the “Better Way” Tax Plan, the blueprint that would eventually become the Tax Cuts and Jobs Act of 2017—the largest overhaul of the US tax code in over 30 years.

The EU public country-by-country data provides information on taxes and profits that do not align with standard financial disclosure requirements.

The new data disclosures will draw significant attention in 2026 and beyond. However, because the data is rooted in financial accounting concepts, affected by timing issues, and shaped by inconsistent reporting regimes, it is poorly suited for drawing strong conclusions about tax policy or corporate behavior.

Digital services taxes address a real concern—the need to adapt taxation to the digital economy—but they are not the right solution. They raise limited revenue, are often passed on to consumers rather than large digital firms, create economic distortions, increase complexity and compliance costs, negatively impact innovation and competitiveness, and risk international retaliation.
Since digital services taxes generate little revenue, place the cost on European consumers and not on large digital companies as intended, and risk escalating trade disputes, policymakers should rethink their strategy.

Europe’s turn toward the UN is ultimately not a sign that governments are ready to resolve fundamental disputes over taxing rights. If anything, international cooperation on the goal that matters most—fair treatment of cross-border trade—is crumbling.

California lawmakers are considering mandating worldwide combined reporting, bringing back a policy the state abandoned in the 1980s due to strong pushback from international trading partners and the federal government.

The variety of approaches to taxation among European countries creates a need to evaluate these systems relative to each other. For that purpose, we have developed the European Tax Policy Scorecard—a relative comparison of European countries’ tax systems.

The Trump administration has rightly shifted its focus from pursuing legislative changes to implementing new permanent rules. But in this shift, it’s crucial that the White House doesn’t lose focus on the larger task at hand.
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. Lawmakers in those states should amend these statutes to ensure that their tax code does not accidentally incorporate a much more aggressive tax on international income than the tax from which they previously decoupled.

Due to the incentive for jurisdictions to implement a qualified domestic minimum top-up tax (QDMTT), Pillar Two leaves a geographic asymmetry. Additional tax revenues would predominantly accrue to low-tax jurisdictions, with high tax jurisdictions receiving little to no increase.
