Lead
On January 5, 2026, the OECD finalized an amended global tax accord that nearly 150 countries backed, but the latest text exempts large U.S.-based multinational companies from the 15% global minimum tax. The change follows negotiations involving the Trump administration and other Group of Seven members and alters a landmark 2021 framework intended to curb profit shifting to low-tax jurisdictions. OECD Secretary-General Mathias Cormann described the pact as strengthening tax certainty; U.S. Treasury Secretary Scott Bessent framed the carve-out as a protection of U.S. sovereignty and businesses.
Key Takeaways
- Nearly 150 countries agreed to the OECD framework as of January 5, 2026, endorsing an amended version of the 2021 deal targeting profit shifting.
- The original 2021 agreement set a 15% global minimum corporate tax; the 2026 amendment exempts large U.S.-based multinationals from that minimum after high-level negotiations.
- Negotiations intensified after a June renegotiation by the Trump administration and congressional moves removing a so-called “revenge tax” provision from federal legislation.
- OECD Secretary-General Mathias Cormann called the agreement a landmark for international tax cooperation aimed at reducing complexity and protecting tax bases.
- U.S. Treasury Secretary Scott Bessent praised the carve-out as preserving U.S. sovereignty and shielding American workers and firms from extraterritorial taxation.
- Tax transparency groups, including the FACT Coalition, warned the amendment risks undoing nearly a decade of progress and allowing the largest U.S. firms to continue using tax havens like Bermuda and the Cayman Islands.
- Senate Finance Chair Mike Crapo and House Ways and Means Chair Jason Smith hailed the finalized deal as aligning with a U.S.-first approach to global tax policy.
Background
The 2021 OECD agreement aimed to create a two-pillar solution: a 15% global minimum tax (Pillar Two) and a reallocation of taxing rights to market jurisdictions (Pillar One). U.S. involvement under then-Treasury leadership, including former Secretary Janet Yellen, helped propel the 2021 framework as a bipartisan international priority to curb profit shifting by companies such as Apple and Nike.
Over the following years, domestic politics in the United States complicated implementation. Congressional Republicans criticized the 2021 terms as weakening U.S. competitiveness, and a provision in a 2025 tax and spending law—informally called a “revenge tax”—became a negotiating flashpoint. In June 2025 the Trump administration reopened talks, and legislative rollbacks in Congress removed leverage that had tied broader U.S. tax enforcement to the OECD compromise.
Main Event
On January 5, 2026, the OECD announced that the amended deal had broad international backing but that an explicit exclusion would apply to large U.S.-based multinationals. Officials said the carve-out emerged from negotiations among G7 countries and U.S. representatives aiming to limit the extraterritorial reach of the global minimum tax on American-headquartered firms.
OECD Secretary-General Mathias Cormann said the agreement enhances tax certainty and protects tax bases, language aimed at reassuring both revenue authorities and multinational companies. U.S. Treasury Secretary Scott Bessent characterized the outcome as a victory for U.S. sovereignty, arguing it prevents foreign tax rules from imposing additional burdens on American businesses.
Critics argue the exemption undermines the core objective of the 15% minimum—to stop companies from shifting profits into low- or no-tax havens such as Bermuda or the Cayman Islands. Tax watchdogs contend that allowing the largest U.S. firms to remain outside the minimum risks perpetuating an international race to the bottom in corporate taxation and weakening enforcement globally.
Analysis & Implications
The exemption for U.S.-based multinationals recalibrates the balance between international cooperation and national sovereignty. Policymakers who prioritized protecting domestic firms argued that an unqualified global minimum could subject U.S. companies to foreign tax regimes and double taxation; opponents say the carve-out opens a loophole that large firms could exploit to maintain low effective tax rates.
For revenue-starved jurisdictions, especially lower-income countries that supported the 2021 framework, the amendment may reduce expected gains from Pillar Two and complicate domestic tax planning. If the carve-out becomes a precedent, other countries may seek similar reciprocal carve-outs or adjustments, weakening the uniformity the OECD sought to create.
Corporate behavior may not change immediately: firms already using profit allocation strategies could preserve advantages while policymakers and tax authorities negotiate implementing rules and enforcement mechanisms. Over time, disputes may move to arbitration, domestic courts, or further multilateral talks if affected countries view the exemption as creating unfair competitive dynamics.
Comparison & Data
| Item | 2021 Framework | 2026 Amended Deal |
|---|---|---|
| Global minimum tax rate | 15% | 15% (with carve-out for large U.S.-based multinationals) |
| Countries agreeing | Over 130 (initial consensus) | Nearly 150 |
| Primary goal | End profit shifting to low-tax havens | Same goal, but with U.S. exemption |
The table shows that while the headline 15% floor remains, the practical coverage has narrowed. That reduction in scope could materially affect projected tax receipts from multinational enterprises and the perceived fairness of the global tax system.
Reactions & Quotes
Officials and stakeholders responded predictably along political and functional lines: multilateral institutions framed the deal as progress on tax certainty, while advocacy groups warned of backsliding.
“This is a landmark decision in international tax co-operation that enhances tax certainty, reduces complexity, and protects tax bases.”
Mathias Cormann, OECD Secretary-General
Cormann presented the package as strengthening predictability for governments and companies, emphasizing reduced complexity in cross-border tax rules.
“A historic victory in preserving U.S. sovereignty and protecting American workers and businesses from extraterritorial overreach.”
Scott Bessent, U.S. Treasury Secretary
Bessent framed the exemption as essential to preventing foreign tax rules from imposing additional burdens on U.S.-headquartered firms and to safeguarding domestic policy space.
“This deal risks nearly a decade of global progress on corporate taxation only to allow the largest, most profitable American companies to keep parking profits in tax havens.”
Zorka Milin, Policy Director, FACT Coalition (tax transparency nonprofit)
Advocacy groups warned that the exemption undermines the core anti-avoidance purpose of the minimum tax and could preserve opportunities for profit shifting.

- Whether any countries will seek formal concessions or retaliatory measures in response to the exemption has not been publicly confirmed.
Bottom Line
The OECD’s January 5, 2026 announcement keeps the 15% minimum rate on paper but narrows the measure’s practical reach by excluding large U.S.-based multinationals after U.S. negotiations. That outcome preserves a political win for U.S. policymakers who sought to limit perceived extraterritorial taxation, while prompting criticism from tax transparency groups and some revenue-seeking jurisdictions.
Going forward, the key items to watch are the technical implementing rules, whether other countries seek similar carve-outs, and how tax authorities and businesses adjust compliance and reporting. The amendment may reduce short-term friction for major U.S. firms but could complicate long-term multilateral efforts to harmonize corporate taxation and curb profit shifting.
