Following the Supreme Court’s February 2026 ruling that IEEPA tariffs were unlawful, importers who paid those tariffs in 2025 are now eligible for refunds. But if your company deducted those tariff costs as business expenses, the refund could be taxable income under the tax benefit rule.
Here’s the situation: many importers deducted tariff costs as ordinary business expenses in 2025, which reduced their taxable income that year. Now that the money is coming back, the IRS will likely want its share. Understanding how and when that tax obligation kicks in is the difference between a clean recovery and an unwelcome surprise.
This article walks through what you need to know and what questions to answer now.
How most importers handled tariff costs in 2025
Not every company absorbed tariff costs the same way, and that matters for how a refund gets taxed.
The most common scenario: companies treated tariff payments as ordinary operating expenses and deducted them on their 2025 tax returns. This reduced taxable income at the time, which felt like the right move when those costs were eating into margins.
Others passed the burden along. Some importers raised prices to customers, effectively recouping the tariff costs through revenue. Others negotiated lower purchase prices from suppliers, sharing or shifting the burden upstream. Many companies did some combination of both.
The tax treatment of your refund hinges on which of these paths your business took—and in what proportion.
When does a tariff refund become taxable income?
This is where the tax benefit rule comes in. Under this well-established principle, if you deducted an expense in a prior year and later recover that amount, the recovery is generally taxable income in the year you receive it.
The logic is straightforward: the original deduction reduced your tax liability. Recovering that cost restores what was previously offset, so the IRS treats the refund as income to balance the ledger.
There’s an important nuance here. Under IRC §111, if the original deduction didn’t actually produce a tax benefit—for example, because the company had net operating losses that year—the refund may not be taxable to that extent. But this exception requires analysis. It’s not a blanket escape hatch.
The bottom line: don’t treat an incoming refund as a windfall until your tax advisor has reviewed how the original deduction was handled and whether the tax benefit rule applies to your specific situation.
What if you’re reimbursing suppliers or customers?
Some importers are now facing a different question: what happens when you received a refund, but someone else actually bore the cost?
Suppliers who absorbed a portion of the tariff burden—whether through negotiated pricing concessions or contractual arrangements—may be coming back to request their share. Similarly, some companies are choosing to pass refunds through to customers who paid elevated prices during 2025.
These reimbursements may be deductible as ordinary and necessary business expenses under IRC §162(a). But deductibility isn’t automatic. You’ll need documentation that ties the reimbursement to a legitimate business purpose: contracts, pricing records, correspondence, or invoices. The stronger your paper trail, the cleaner the deduction.
Three questions to answer now
Whether your refund has already arrived or is still in process, your finance team should work through three questions:
1. Did your company deduct tariff payments as expenses?
If yes, a refund could trigger taxable income. The size of that tax obligation depends on your tax rate and the amount recovered.
2. Are you receiving a refund, and how much and when?
Timing matters—but the answer depends on your accounting method. Cash-basis taxpayers generally recognize income in the year the refund is received. Accrual-basis taxpayers, however, must recognize income when the right to receive it is fixed and the amount is determinable, which could occur before actual receipt. If a refund claim is approved in 2026 but paid in 2027, an accrual-basis taxpayer may face a 2026 tax obligation without the cash to pay it. Understanding your accounting method and refund timeline allows for proactive planning, including estimated tax payments if needed.
3. Do you have obligations to reimburse suppliers or customers?
Contractual, relational, or ethical obligations to share the refund affect both your net recovery and your deduction opportunities. Document those obligations clearly before any money changes hands.
The answers to these three questions map your tax exposure and identify where planning opportunities exist.
The tax implications don’t wait—and neither should you
Tariff refunds are arriving—some importers have already received them, others are still waiting. Either way, the tax implications are real and require attention now. The rules here are well-established, and the analysis isn’t complicated, but it does need to happen. The companies that come out ahead will be the ones that treat this as a planning opportunity, not an administrative afterthought.

Frequently asked questions about tariff refund tax treatment
Are tariff refunds automatically considered taxable income?
Not automatically, but in most cases, yes. If your company deducted tariff costs as business expenses in 2025 and those deductions reduced your tax liability, the refund is generally taxable under the tax benefit rule in the year it’s received. The exception under IRC §111 may apply if the original deduction did not produce a tax benefit, but this requires a case-by-case assessment.
What is the tax benefit rule, and how does it apply to tariff refunds?
The tax benefit rule is a long-standing IRS principle: when you recover an amount previously deducted, that recovery is treated as taxable income. For tariff refunds, this means the deduction your company took in 2025 essentially gets “unwound” when the money comes back.
Can we deduct payments we make to reimburse suppliers or customers?
Generally, yes. Reimbursements to suppliers or customers who bore a portion of the tariff costs can be deducted as ordinary and necessary business expenses under IRC §162(a). Clear documentation of the business purpose is critical to supporting that deduction.
What if our company passed tariff costs to customers through higher prices?
If you raised prices to recoup tariff costs rather than deducting them directly, the tax treatment of the refund may differ. In that scenario, you may not have taken a direct deduction—which affects whether the tax benefit rule applies. This is one of the key variables your tax advisor should assess.
When should we address the tax implications of our tariff refund?
Now, regardless of whether the refund has arrived or is still in process. If you’ve already received it, the tax event has occurred and planning should happen before your return is filed. If you’re still waiting, proactive planning allows you to prepare for potential tax obligations, account for your accounting method (cash vs. accrual), and structure any supplier or customer reimbursements in a tax-efficient way.
What if related parties are involved in our supply chain?
If your company transacts with related parties—such as affiliated suppliers or parent companies—transfer pricing considerations may come into play when receiving refunds or making reimbursements. These situations add a layer of complexity that warrants specific guidance from your tax advisor.
