Key Takeaways

  • Starting with Estonia, countries are starting to air opposition to a special U.S. exemption to Pillar Two taxes.
  • These countries want to receive the same treatment as the U.S.
  • If the differences can’t be worked out before year-end, the world runs the risk of another trade war with the U.S.
  • As Pillar Two disagreement continues, countries press ahead with implementation.
  • The IRS is testing a new international tax theory in a case against Meta.

December was supposed to be when nations at the G-7 and Organization for Economic Cooperation and Development finalized details of the side-by-side agreement with the United States over the Pillar Two 15% global minimum tax. But that timeline has been thrown into doubt as countries are becoming more public about objections.

If the impasse stretches into 2026, it could be a whole new ballgame. 

When it was announced back in June, all of the G7 and OECD countries were on board—along with the other countries in the Inclusive Framework, the 147-jurisdiction coalition also implementing the minimum tax. Or at least, no one in the IF publicly protested. The agreement would exempt U.S. companies from the Pillar Two taxes that other countries would apply if entities in those companies are taxed at lower than 15%. The agreement was announced as Congress considered Sec. 899, a retaliatory measure against Pillar Two countries. After the agreement, lawmakers removed that provision from the One Big Beautiful Bill Act.

The June announcement left many details unresolved—including how the exemption would work and how broad it would be. Negotiators were also publicly mulling whether it would expressly exempt only the U.S., or if it would be a country-neutral set of standards. That issue has apparently come to the forefront as Estonia issued a statement last week stating opposition to the agreement, unless it could receive the same treatment as the U.S. They say they have little to gain and face significant administrative burdens from Pillar Two compliance.

According to reports, also raising objections are Malta, Latvia, Lithuania, Slovakia, the Czech Republic—and China. (Poland also protested at one point, but has decided to keep supporting the measure, Bloomberg Tax has reported.) Most of these countries won’t have to comply with Pillar Two immediately, due to their small number of qualifying corporate taxpayers. But they want assurances that their exclusion will be permanent. China, of course, is a much bigger player, and it has never been a full-throated supporter of the project. These reluctant participants may spot an opening to leave the project, or kill it altogether.

Despite these signs of discord, the U.S. still seems confident they’ll reach a deal, with U.S. Treasury Secretary Scott Bessent urging countries to move ahead in a statement on X, formerly known as Twitter. They do appear to be on the cusp—the OECD even apparently released agreement details in error last week, only to quickly retract them.

Originally, the rationale for giving the U.S. special treatment was that it already has a global minimum tax regime with the tax on global intangible low-taxed income. (Now called net CFC tested income.) U.S. officials said the system was already “robust” enough to block profit-shifting, the ostensible goal of Pillar Two. But not everyone seems to totally agree with this logic, and other countries are now asking for similar treatment despite not having a minimum tax regime.

Next year, the temporary safe harbor that has been protecting U.S. businesses from Pillar Two taxation will expire, and they could be subject to new foreign taxes. Republicans have Congress have been adamant that if this happens, they’ll re-enact Sec. 899, and a trade war could commence.

This could just be the usual rhetoric and jockeying that happens before compromises are made. Or, it could be a sign that this fragile truce is breaking down. We’ll find out very soon.

Noteworthy Items This Week 

Countries keep implementing pillar 2, with the Dutch Tax Administration issuing guidance, the Swedish government publishing global minimum tax amending legislation in its official gazette, and the Uruguayan parliament approving a domestic minimum top-up tax.

The Dutch Tax Administration on December 15 published guidance about how tax under the Netherlands’ income inclusion rule, a key provision of the Minimum Tax Act, should be calculated when a low-taxed group entity is transferred from a Dutch parent entity to a parent entity in another state.

The guidance confirms that, in the event of an internal transfer, the IIR top-up tax of that transferred entity must be allocated on a pro rata basis over the reporting year based on the length of each parent entity’s direct or indirect controlling interest.

 

IRS Takes a New Shot at Meta’s Foreign Tax Strategy – Richard Rubin, The Wall Street Journal:

This time around, the government is debuting an untested legal argument that has raised alarm bells among tax lawyers and cheered supporters of a more assertive government approach. An IRS win would give the agency a new tool against corporate transactions that shift profits to low-tax countries, an area where it has struggled.

The core issue is how the U.S. taxes income from intangible assets such as patents that can be easily moved or licensed across borders. Especially before the U.S. cut tax rates in 2017, companies had incentives to use transactions with subsidiaries to concentrate profits in countries with low tax rates and concentrate deductions in the U.S.

 

OECD Tackles Tax Complexities of International Remote Work – Gregory Price and Edward Hughes, Bloomberg Tax:

Expert witnesses and former Eaton officials during the first weeks of trial addressed the company's lowered credit rating after the acquisition, which Eaton argues justified the high interest and guarantee fees. They also spoke about the data used to calculate the rating and the company's decision, as part of its restructuring, to transfer a $14 billion asset from a U.S. Eaton subsidiary to Eaton PLC.

Tax Court Judge Albert Lauber's questions seemed to indicate that while he viewed the guarantee fees as having some value, he considered the interest rates artificially high and was skeptical of the lowered credit rating assigned to the U.S. company after the acquisition. Other comments suggest he isn't likely to find that the IRS abused its discretion in the case — or give much weight to its alternative argument that the debt was not real and should be recharacterized as equity.

 

Corporate Transparency Act Block Lifted After Trump Rule Shakeup – John Woolley and Tristan Navera, Bloomberg Tax ($):

The act—which requires companies to report their beneficial owners to the Treasury Department’s Financial Crimes Enforcement Network—"facially regulates economic activity,” the US Court of Appeals for the Eleventh Circuit said. Therefore, the constitutional challenges to the law fail, the appeals court said, remanding the case to the US District Court for the Northern District of Alabama and lifting that court’s stay on enforcement.

“By requiring these corporate entities to provide beneficial ownership information, the CTA regulates how they operate and the level of secrecy with which they do business,” Judge Andrew L. Brasher wrote for the court. “The maintenance and operation of a separate corporate entity is comparable to other regulated activities the Supreme Court has found commercial in nature.”

 

The United Kingdom’s DST has generated much more revenue than the government originally estimated when it introduced the DST in 2020. It is performing so well that the government is considering ways to expand the measure, and the United Kingdom is not alone.

For example, French lawmakers moved in October to increase the rate of the country’s DST, and Italy expanded its DST in 2024. Countries are revising — or attempting to revise — their DSTs, and these efforts raise a question: How are these DSTs performing against their initial revenue estimates? A review of five DSTs from the United Kingdom, Italy, France, Spain, and Austria shows a mixed bag of outcomes. Some countries’ DSTs are exceeding their estimates while others’ are falling short. No matter the outcome, it is apparent that some countries are using their DST results as a justification to enhance their DSTs. Revenue performance — good or bad — is being used politically to entrench DSTs, not retire them. Simply put, some countries are refusing to take “no” for an answer when it comes to maintaining DSTs, and this raises questions for the future of unilateral digital taxes.
