Global Tax Showdown: The US ‘Revenge Tax’ Threat, OECD Delays, & G7 Deal

The world of international taxation is constantly shifting, but few legislative proposals have created as much geopolitical tension as the recently proposed (and subsequently removed) US ‘Revenge Tax,’ formally known as Internal Revenue Code Section 899.
For international businesses, especially those planning US expansion or currently operating an LLC or C-Corp in the States, these tax policy debates are more than just political theater—they represent genuine financial risk. They underscore the critical need for expert guidance in US tax filing and US company formation.
At TheTaxBooks, led by Principal Consultant Kishore Chennu (MBA, CMA, EA-IRS (US)), we specialize in translating these complex global tax movements into clear, actionable advice for our international clientele. Here is a deep dive into the ‘Revenge Tax,’ its connection to the OECD’s global tax deal, and why the threat of its revival remains relevant today.

Understanding the Core Conflict: The Global Minimum Tax (OECD Pillar Two)

The controversy surrounding the ‘Revenge Tax’ is directly linked to a massive global effort to reform corporate taxation: the OECD/G20 Inclusive Framework on Base Erosion and Profit Shifting (BEPS) 2.0, specifically its Pillar Two.

For years, multinational enterprises (MNEs) have been able to shift profits to low-tax jurisdictions. Pillar Two is designed to stop this.

The 15% Global Minimum Tax Rate and the 'GloBE Rules'

Pillar Two is built around the Global Anti-Base Erosion (GloBE) Rules, which aim to ensure MNEs with annual revenues over €750 million (approx. $825 million) pay a minimum effective tax rate of 15% on their profits in every jurisdiction where they operate. The two main mechanisms are:

  • Income Inclusion Rule (IIR): Allows the parent company’s jurisdiction (e.g., the US) to levy a “top-up tax” on low-taxed income earned by its foreign subsidiaries.
  • Undertaxed Profits Rule (UTPR): Acts as a backstop, allowing other countries to collect the top-up tax if the parent company’s jurisdiction has not fully implemented the IIR.

The US has not yet adopted the full GloBE Rules, which created an opening for other countries to potentially tax US MNEs under the UTPR—a situation the US government sought to avoid.

The US Counter: What Was the 'Revenge Tax' (Section 899)?

The ‘Revenge Tax’ (Section 899) was a legislative provision proposed within the US tax bill known as the “One Big Beautiful Bill Act” (OBBBA). It was explicitly designed as a retaliatory measure intended to pressure foreign countries into not applying the OECD’s new minimum tax rules (like the UTPR or Digital Services Taxes) to US companies.

Who Was Targeted by the Proposed Section 899?

Had it been enacted, Section 899 would have significantly increased US tax burdens on income earned by certain foreign individuals and entities from “discriminatory foreign countries.”

The primary targets were:

  • Foreign Individuals and Corporations: Those who are tax residents of countries imposing “unfair foreign taxes.”
  • Foreign Governments/Sovereign Wealth Funds: The tax-exempt status of these entities could have been removed.
  • US Corporations: Domestic corporations majority-owned by foreign persons in “offending” jurisdictions would have faced stricter Base Erosion and Anti-Abuse Tax (BEAT) rules.

The core mechanism was an escalating additional tax rate (proposed to be 5% annually, potentially capped at 15% or 20%) on U.S.-source investment income like dividends, interest, and royalties.

The Key Trigger: 'Unfair Foreign Taxes'

The penalty would have been triggered if a country was deemed to impose “unfair foreign taxes” on American companies. This definition primarily targeted:

  • Digital Services Taxes (DSTs): Taxes levied by many European nations and others on the revenues of large technology companies.
  • Undertaxed Profits Rules (UTPRs): The enforcement mechanism of the OECD’s Pillar Two.
  • Diverted Profits Taxes (DPTs): Taxes aimed at companies perceived to be shifting profits out of a country.

The G7 Deal: A Temporary Truce?

In mid-2025, the US government and its Group of Seven (G7) allies reached an understanding that led to the removal of Section 899 from the final US tax bill. This agreement effectively served as a temporary truce in the global tax war.

The 'Side-by-Side' Exemption for US Multinationals

The G7 compromise centered on a commitment by the G7 nations to exempt US multinationals from key parts of the OECD’s Pillar Two rules, particularly the UTPR, by implementing a “side-by-side” approach. This special treatment would effectively:

  • Preserve US Tax Incentives: Protect existing US tax treatments and incentives (like R&D credits) without being subjected to foreign top-up taxes.
  • Exempt US Firms: Ensure American companies would not be hit by the UTPR in partner nations.

In exchange for this commitment, the US dropped the highly controversial ‘Revenge Tax.’

Why is the 'Revenge Tax' Being Discussed for Revival?

The G7 deal was a political agreement, but its implementation depends on the slow, technical process of the OECD’s working groups. Delays and objections have put the agreement under severe stress.

Persistent OECD Implementation Challenges

Despite the G7 understanding, the technical negotiations for granting specific US exemptions under Pillar Two have stalled. Several countries have voiced strong criticism that a “side-by-side” system would:

  • Undermine the Global Tax’s Integrity: By creating a major exception for US companies.
  • Create a Competitive Disadvantage: By forcing non-US companies to comply with the 15% minimum tax while US companies get an exemption.

Because a final, technical consensus at the OECD is proving elusive, the stability of the G7 deal is in question.

Political Pressure and the Risk of Unilateral Action

US lawmakers have indicated support for reviving Section 899 if the OECD fails to finalize the agreed-upon Pillar Two exemptions by upcoming deadlines.

  • This revival would likely be pursued through a supplemental spending bill or other legislative action.
  • The goal remains the same: to use the threat of higher US taxes on foreign investors as a powerful bargaining chip to compel international partners to accommodate the US position.

In short, the threat of the ‘Revenge Tax’ being enacted is directly proportional to the lack of progress on the OECD’s global tax framework.

What This Means for Foreign Businesses and Investors in the US

For foreign entrepreneurs and global companies, especially those based in regions like India and looking to establish a US presence (LLC, C-Corp, etc.), this policy uncertainty highlights a crucial reality: US international tax law is volatile and unforgiving of mistakes.

  • Investment Risk: The potential for a sudden, retaliatory tax increase on U.S.-source income (dividends, royalties) could significantly lower the after-tax return on foreign investments in the US, affecting capital market and real estate decisions.
  • Compliance Complexity: Even without the Revenge Tax, the US tax landscape involves complex reporting for foreign-owned entities (e.g., Form 5472 for foreign-owned U.S. disregarded entities like single-member LLCs, and Form 5471 for certain foreign corporations). The political instability only adds a layer of planning risk.
