How IEEPA Refunds Are Taxed: The Tax Benefit Rule, Timing, and Interest

This is a summary of published views from accounting firms. It is not tax advice. Talk to your CPA.

The tax benefit rule

If you deducted the tariffs, or they reduced your taxable income through cost of goods sold, the refund is generally taxable to the extent that earlier deduction gave you a tax benefit. Firms note the rule generally applies to the same taxpayer that took the deduction, which matters after mergers or restructurings.

When to report it

• Cash method: generally when the refund is received.
• Accrual method: generally when all events fixing the right to the refund have occurred, often when it is approved or paid, whichever is first. RSM notes the right may not be fixed while a claim is under substantive government review.
• Firms report that amending prior-year returns is generally not the approach.

Inventory

Refunds tied to goods still in inventory generally reduce the cost of that inventory rather than creating separate income, and flow through cost of goods sold when the goods are sold.

Interest

Interest CBP pays on the refund is ordinary taxable interest income. It is not a reduction of cost of goods sold.

What this means for importers

Give your CPA a list of refunds by entry, with dates and interest, and whether the related goods are still in inventory. See how to pull ACE refund reports.
