The U.S. has introduced a new provision, Section 899 of the Internal Revenue Code, as part of the “Defending American Jobs and Investment Act.” This provision would allow the government to impose retaliatory taxes on foreign investors from countries that levy unfair taxes on U.S. companies. The focus is particularly on digital services taxes and undertaxed profit rules.

Key provisions of Section 899

  • Imposes up to a 20-percentage point tax increase on investors from designated foreign countries

  • Grants the U.S. authority to override existing bilateral tax treaties

  • Adjusts BEAT (Base Erosion and Anti-Abuse Tax) calculations for U.S. corporations linked to targeted jurisdictions

  • Removes Section 892 tax exemptions for foreign governments and sovereign wealth funds

What triggers Section 899?

  • The Treasury Department will issue a quarterly list of countries that impose discriminatory tax measures on U.S. businesses

  • Unfair tax actions include digital services taxes or OECD-aligned undertaxed profit rules

  • The retaliatory measures phase in over four years after enactment or foreign tax implementation

  • Withholding agents may receive grace periods through December 2026 for compliance

Affected income categories

Foreign investors from flagged countries may face increased U.S. taxes on:

  • FDAP income (dividends, interest, royalties, rents)

  • Effectively Connected Income (ECI) from trade or business operations

  • Capital gains from real estate under FIRPTA

  • Branch profits and private foundation excise tax

Implications for global investors

  • Sovereign wealth funds from affected countries could lose tax-exempt status under Section 892

  • Multinational corporations may face higher compliance costs and loss of treaty benefits

  • U.S. assets could become less attractive to foreign capital due to increased tax risk

Market and political reactions

  • Business groups warn the proposal could deter over $40 trillion in global investment into the U.S.

  • Senate Republicans are exploring revisions to narrow the scope of Section 899

  • Supporters claim the move protects U.S. sovereignty from foreign extraterritorial tax practices

Forward outlook

If passed, Section 899 would mark a major shift in U.S. international tax policy. It represents a more aggressive, unilateral stance in response to global tax measures targeting American firms. The outcome of legislative debate on this provision could reshape foreign capital flows and diplomatic tax negotiations.
