In a landmark ruling on February 20, 2026, the U.S. Supreme Court (SCOTUS) invalidated several tariffs previously imposed under the International Emergency Economic Powers Act (IEEPA). The Court determined that the executive branch exceeded its statutory authority by utilizing emergency powers to implement broad, revenue-raising import levies without specific Congressional authorization.
This decision directly nullifies several high-profile tariffs enacted in 2025, including reciprocal duties on global imports and specific levies targeting goods from Canada, Mexico, and China. While tariffs under other frameworks—such as Section 232 (national security) and Section 301 (unfair trade practices)—remain in effect, this ruling opens a massive window for duty refunds that could reach hundreds of billions of dollars.
The Interplay with Transfer Pricing
The connection to transfer pricing compliance is immediate and complex. Under U.S. IRC Section 482 and OECD Guidelines, multinational enterprises (MNEs) must ensure that intercompany transactions reflect arm’s-length pricing.
Tariffs typically inflate “landed costs,” which are then baked into transfer pricing models. The invalidation of these duties creates several compliance hurdles:
- Retroactive Adjustments: Refunded duties may be treated as a reduction in COGS or as taxable income, requiring a look-back at 2025 intercompany charges to prevent “windfall” profits in the wrong jurisdiction.
- Double Taxation Risks: If a U.S. entity receives a refund but the foreign counterparty has already paid tax on the original inflated price, MNEs face significant audit exposure without careful documentation.
- Global Ripple Effects: Changes in U.S. cost structures necessitate immediate alignment with local rules in different regions to maintain global consistency in arm’s-length standards.
Brief Timeline Since Implementation
- Early 2025: Following President Trump’s inauguration, IEEPA tariffs are imposed via executive orders, including 25% duties on most Canadian and Mexican imports, 10% on Chinese goods for drug trafficking, and reciprocal tariffs on all trading partners to address trade deficits.
- Mid-2025: Tariffs take effect, prompting companies to adjust supply chains, embed costs in transfer pricing, and face increased landed costs in sectors like electronics and manufacturing.
- Late 2025: Legal challenges mount, with cases advancing to the Supreme Court amid ongoing modifications to tariff rates.
- February 20, 2026: Supreme Court strikes down IEEPA tariffs, invalidating their use for revenue-raising purposes but preserving other tariff authorities.
- Post-Ruling (March 2026 onward): Administration shifts to alternative measures, including a temporary 15% tariff under Section 122, with plans for new investigations under Sections 301 and 232.
Managing 2025 Compliance and Refund Claims
For 2025, when IEEPA tariffs were in full force, many multinationals mitigated impacts by reshaping supply chains, negotiating contract terms to shift duty burdens, or adjusting transfer pricing policies to pass costs through intercompany entities. Post-ruling, companies are now pursuing refunds through U.S. Customs and Border Protection, often requiring protective claims and documentation to prove payments as the importer of record. This transition involves evaluating tax implications, such as amending 2025 returns for refunded amounts treated as income, and recalibrating transfer pricing to reallocate refunds without violating arm’s-length principles. Globally, MNEs are conducting reviews to ensure compliance with foreign tax regimes, avoiding penalties from mismatched pricing and the risk of double taxation.
Outlook for 2026: Continued Volatility
Looking ahead to 2026, uncertainty continues to loom as the administration shifts away from the invalidated IEEPA-based tariffs and pivots to alternative mechanisms, such as temporary Section 122 duties (initially set at 10% globally and potentially rising to 15%) and new investigations under Sections 301 and 232 that may broaden or intensify import levies across larger trade volumes. MNEs are bracing for persistent volatility by prioritizing flexible and resilient supply chain adaptations, strengthening transfer pricing documentation to reflect fluctuating costs and potential refunds, and conducting thorough scenario planning to mitigate heightened IRS and international audit risks.
Although opportunities for substantial tariff refunds provide some immediate financial relief, maintaining rigorous, long-term compliance remains crucial to adeptly manage the fluid U.S. and global regulatory environment.
