On July 4, 2025, the U.S. Congress passed the One Big Beautiful Bill (H.R. 1)—a sweeping piece of legislation covering everything from defense spending to energy tax credits. Tucked within its early drafts were controversial international tax provisions that had major implications for global investors, especially Canadians with exposure to U.S. markets.
Although some of the most aggressive measures were ultimately removed from the final version, it’s essential to understand what changed, what stayed the same, and how this will affect cross-border investment and business.
Summary of the One Big Beautiful Bill’s International Tax Provisions
Section 899: Proposed but Removed
Originally, the bill included Section 899, which proposed a variable surtax on cross-border payments made to residents of so-called “discriminatory foreign countries,” including Canada, France, India, and the United Kingdom.
Under the draft language, U.S. companies would have been required to withhold an additional 5% per year, up to a maximum of 50%, on interest, dividends, royalties, and similar payments made to Canadian recipients. This was widely seen as a retaliatory measure tied to digital services taxes and broader trade disagreements.
However, after pushback from international allies and financial markets, Section 899 was stripped from the final bill. The decision came following high-level talks with G7 partners in late June.
What Remains: Treaty Withholding Rates Stay Intact
With the surtax provision removed, the Canada–U.S. Tax Treaty remains fully in effect. This means:
- A 15 percent withholding tax continues to apply to dividends paid from U.S. companies to Canadian residents in non-registered accounts.
- No U.S. withholding tax applies to dividends held inside registered retirement accounts such as RRSPs or RRIFs.
- 5% withholding applies to intercompany dividends paid from a U.S. subsidiary to a Canadian parent corporation, under certain ownership conditions.
- 10% withholding remains on certain interest payments not-exempt under portfolio interest rules.
These provisions are critical for both Canadian individuals investing in U.S. markets and businesses engaged in cross-border corporate structures.
Impact on Canadian Stakeholders
Individual Investors
Canadian residents who own U.S. dividend-paying stocks outside of a RRSP will continue to face the standard 15% withholding tax on periodic payments and 25% on lump-sum payments. Investors using registered retirement accounts such as RRSPs or RRIFs will continue to benefit from tax deferral, as long as the U.S. recognizes the account under the treaty.
The threat of a punitive surtax would have made U.S. dividends significantly less attractive. Its removal avoids unnecessary tax drag on Canadian portfolios.
Registered Accounts and Retirement Planning
For Canadians planning retirement with U.S. investments, this is a relief. The ability to hold U.S. stocks in an RRSP without U.S. withholding tax continues to make cross-border portfolio diversification viable and tax-efficient.
Canadian Corporations
Canadian businesses that operate across the border or own U.S. subsidiaries also benefit from the status quo. Intercompany dividends remain subject to only a 5% withholding, and there is no additional surtax or discriminatory rate. This preserves the efficiency of multinational structures and avoids increased repatriation costs.
Financial Institutions and Advisors
Cross-border advisors and wealth managers will not need to revise client strategies around new withholding regimes. This preserves current tax planning approaches, income projections, and investment strategies. It also avoids potential friction in financial product design or the use of U.S.-domiciled ETFs.
Why This Matters for the Canada–U.S. Relationship
The One Big Beautiful Bill’s early inclusion of Section 899 raised serious concerns among economists and financial institutions. Had it passed, it could have triggered retaliatory measures from Canada, harmed bilateral trade, and reduced U.S. access to Canadian capital. Instead, the decision to remove the surtax provision:
- Respects the existing Canada– U.S. tax treaty,
- Signals ongoing support for cross-border cooperation, and
- Reinforces the importance of treaty stability in maintaining investor confidence.
This decision also aligns with Canada’s repeal of its digital services tax, which had been a source of tension and was likely a factor in averting the retaliatory provisions.
Key Takeaways
| Area | Outcome |
| Withholding on U.S. Dividends | 15% in non-registered accounts; 0% in RRSPs/RRIFs |
| Intercompany Dividends (U.S. to Canada) | 5% continues under treaty |
| Interest and Royalties | Treaty provisions continue unchanged |
| Surtax Proposal (Section 899) | Removed from final legislation |
| Impact on Cross-Border Investment | Positive; preserves current planning structures |
Looking Ahead
While the final version of the One Big Beautiful Bill maintains stability for Canadian investors, it’s worth monitoring the following developments:
- OECD/G7 negotiations on digital tax frameworks could reintroduce pressure on cross-border tax policy.
- Future U.S. administrations may revisit retaliatory tax tools, depending on geopolitical or trade shifts.
- Canadian regulatory responses to international tax changes may affect overall coordination.
For now, Canadian investors and businesses can continue engaging with U.S. markets under the same terms they’ve come to rely on without the fear of sudden punitive tax increases.
