Tariff Refunds Raise Complex Tax and Transfer Pricing Questions

What’s at Issue
The Supreme Court invalidated a broad range of Trump-era tariffs, potentially opening the door to more than $170 billion in refund claims.

While this creates a significant opportunity for importers, the ruling does not clarify whether — or how — refunds will be issued. More importantly, for multinational groups, any refund received could trigger complex tax and transfer pricing consequences.

Many companies previously adjusted intercompany pricing, margins, or contractual arrangements to manage tariff costs. If refunds are received, determining which entity is entitled to the funds may not be straightforward.

Current Status

• Refunds are possible, but the administrative process remains unclear.
• The Court did not provide guidance on how the government would return collected tariffs.
• Companies may face scrutiny from both U.S. and foreign tax authorities regarding how refunds are allocated.
• Conflicting jurisdictional positions could arise if different entities bore the economic burden of the tariffs.
• Businesses that implemented tariff mitigation strategies may need to reassess or unwind prior transfer pricing adjustments — even as new tariffs are being introduced.

In short, while the decision creates potential recovery opportunities, it introduces significant compliance and planning challenges.

What Companies Should Be Doing

Review Intercompany Pricing
Analyze how tariff costs were allocated and which entity ultimately bore the risk.

Assess Arm’s-Length Compliance
Determine whether refund allocations create new intercompany transactions requiring support under transfer pricing rules.

Examine Contracts
Review supplier and customer agreements to confirm whether costs were passed through and whether refund rights exist.

Strengthen Documentation
Ensure contemporaneous support exists for prior pricing adjustments and for the treatment of any refunds.

Monitor Ongoing Trade Developments
With new tariffs already announced, mitigation and transfer pricing strategies remain critical.
