The Tax Cuts and Jobs Act (TCJA) in 2017 took a new direction for the treatment of U.S. multinationals. Six significant reforms departed from the old system:
The U.S. no longer has a worldwide tax system for taxing corporate income. But it does not have a truly territorial system either. Instead, the U.S. now has a hybrid system with some worldwide taxation, without deferral, for certain foreign income because of GILTI and Subpart F and a tax on certain cross-border transactions.
Countries participating in the OECD Inclusive Framework’s negotiations on cross-border tax rules hope to reach an agreement by mid-2021. After negotiations stalled somewhat in 2020, there is hope that US Treasury Secretary Janet Yellen’s commitment to reaching an agreement will allow progress to be made this year.
The posts below include our research and analysis of policies related to cross-border tax rules, including Global Intangible Low Tax Income (GILTI), Foreign Derived Intangible Income (FDII), Base Erosion and Anti-abuse Tax (BEAT), and the Global Anti-base Erosion (GloBE) rules in the context of the OECD’s Inclusive Framework on Base Erosion and Profit Shifting (BEPS).

Over the course of the last year, it has become clear that Democratic lawmakers want to change U.S. international tax rules. However, as proposals have been debated in recent months, there are clear divides between U.S. proposals and the global minimum tax rules.

The international corporate tax changes in President Biden’s tax plan would increase tax rates on domestic income more than on foreign income, resulting in a net increase in profit shifting out of the US, according to our Multinational Tax Model.

Since only U.S. businesses pay the GILTI tax, not foreign businesses, it makes U.S.-based brands less competitive abroad. Whatever its intentions, GILTI is a flawed policy, and doubling down on it will hurt us abroad, and at home.
The Biden campaign and Senate Democrats identified changes to GILTI that would increase the taxes U.S. companies pay on their foreign earnings. Rather than tacking on changes to a system that is currently neither fully territorial nor worldwide, policymakers should evaluate the structure of the current system with a goal of it becoming more, not less, coherent.

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.

While there are many factors that affect a country’s economic performance, taxes play an important role. A well-structured tax code is easy for taxpayers to comply with and can promote economic development while raising sufficient revenue for a government’s priorities.

Since digital services taxes deliver limited revenue, shift the burden to European consumers, and risk provoking trade disputes, it’s time for policymakers to rethink their approach.
Massachusetts lawmakers should look for opportunities to reform the tax code, revamp the state’s competitiveness, and stem the tide of outmigration. This bill, by contrast, would double down on the economically uncompetitive features of the Commonwealth’s existing tax code. Aggressively expanding NCTI inclusion is not productive or competitive.

Instead of getting stuck in a reactionary posture, European countries should simply aim for competitiveness, and the EU can support that work with stronger, more stable trade relationships.
Rather than returning to a world of retaliatory tax measures and transatlantic disputes, the OECD should continue to decrease the compliance costs of Pillar Two by simplifying the rules to reduce any possible risk that the US has a compliance cost advantage and working with G7 countries on a side-by-side solution.

The US has a reasonably robust system for containing profit shifting; it is in effect already working towards the Pillar Two goals. Its negotiating posture is in many cases curbing unreasonable sidetracks, not undermining the whole project.
As energy prices have declined, European countries have switched the focus of their windfall profits taxes—a one-time tax levied on a company or industry when economic conditions result in large, unexpected profits—from energy providers to the banking and financial sector.

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.
The agreement represents a major change for tax competition as well, and many countries will rethink their tax policies for multinationals. However, the US will continue to chart its own course, and other countries may prefer to do the same, depending on the final outcome of the G7 statement.

We estimate the OBBBA will reduce federal taxes on average for individual taxpayers in every state. Across all individual tax filers throughout the US, the average tax cut per taxpayer will be over $3,700 in 2026.
