U.S. Customs and Border Protection has collected roughly $2 billion per day in contested tariffs since President Trump imposed them using emergency authority—money that now totals more than $133 billion and may need to be refunded if the Supreme Court rules against the administration after 99 days of deliberation since oral arguments.
But if the Court strikes down these tariffs, most of the people who paid them won’t see a dime back.
The path from a victory to an actual refund check involves a maze of protest deadlines, administrative procedures, and federal budget constraints. This system effectively filters out small businesses while letting sophisticated corporations recover their costs. A constitutional question—can the president do this?—becomes a practical answer that depends almost entirely on whether you had a customs attorney on retainer when the tariffs hit.
Protest Deadlines and the Timing Problem
When Trump imposed the contested tariffs starting in February 2025, importers faced a choice that most didn’t fully understand at the time. Pay the tariffs and keep importing, or file a formal protest with Customs within 180 days of liquidation—the date when U.S. Customs finalizes what you owe.
For entries that got hit with tariffs in February 2025, liquidation happened around mid-December. The protest deadline fell around mid-June 2026.
The Court heard arguments in November 2025 and still hasn’t issued a decision as of mid-February 2026. Companies that paid tariffs in the first few months of 2025 have already lost their right to contest those charges if they didn’t file protests before their deadline passed.
You could have paid $500,000 in tariffs in March 2025, fully intending to get a refund once the Court ruled. Then you discover in July 2026 that your protest window closed before they even announced their decision. The money is gone.
Major retailers saw this trap coming. Costco, Ray-Ban’s parent company, Revlon, Kawasaki Motors—they all filed protective lawsuits in the Court of International Trade starting in November 2025. Nearly 1,000 such lawsuits got filed by late December, all paused while waiting for the decision.
That litigation strategy requires knowing the trap exists in the first place, having lawyers who specialize in customs law, and having the cash flow to pay those lawyers while also paying the tariffs themselves.
Small importers—the specialty retailer bringing in $3 million worth of goods annually, the manufacturer importing components from a single supplier—typically have none of those things. Analysis of CBP protest records shows that companies importing over $100 million annually filed protests about 60 percent of the time. Companies importing under $5 million? About 15 percent.
If the Court strikes down the tariffs and limits refunds to companies that filed timely protests, refunds will flow overwhelmingly to large corporations. Small businesses will eat the cost of what the Court itself ruled was an unconstitutional tax.
The $133 Billion in Collections
The accumulation happened in waves. First came the “trafficking tariffs” on China, Mexico, and Canada—supposedly to address drug smuggling and illegal immigration. Then the sweeping “reciprocal tariffs” on nearly all U.S. trading partners, effective April 2, 2025.
Steel and aluminum got hit hardest. By May 2025, tariffs on both reached 50 percent. When layered on top of earlier steel and aluminum tariffs from Trump’s first term, effective rates hit 39.8 percent. A company making automobile frames paid tariffs on the raw steel input, then again on the finished product. The accumulated collections on steel and aluminum alone: $35 billion to $40 billion.
China-specific tariffs layered even higher. A 10 percent “fentanyl” charge on top of 20 percent reciprocal tariffs, combined with pre-existing China tariffs from Trump’s first term that could reach 25 percent. Cumulative rates of 45 percent or more on consumer electronics, textiles, footwear, furniture. Industries with razor-thin margins suddenly faced costs that exceeded their entire profit margin. Collections on Chinese goods: over $50 billion.
A manufacturing company importing $10 million in components annually faced roughly $1 million in additional costs—assuming they didn’t change suppliers or shut down entirely. For retailers like Costco, which estimate that one-third of their U.S. sales come from imported goods, the exposure runs into hundreds of millions of dollars.
Every week the Court continues deliberating adds another $14 billion to the pile.
The Bush Steel Tariffs: Historical Precedent
In March 2002, President George W. Bush imposed temporary tariffs of 8 to 30 percent on imported steel. The World Trade Organization ruled them illegal in November 2003. Bush withdrew them in December 2003.
Then came the refund process. Importers had to file claims with CBP, provide documentation proving payment, and establish eligibility. Some refunds got processed within 6 to 12 months. Others took 2 to 3 years, particularly for importers with disputes about eligibility or incomplete documentation.
Total refunds issued were substantially less than total tariffs collected. Many importers never filed claims. Some missed procedural deadlines. Others couldn’t adequately document their payments.
That was for steel tariffs that generated maybe $2 billion in collections. We’re now talking about $133 billion—more than 60 times larger. The Congressional Budget Office projects that processing IEEPA refunds would require both new appropriations and administrative restructuring of CBP’s refund operations. Even on an expedited basis, most claims would take 18 to 24 months to resolve. Without supplemental funding, the CBO estimates 36 to 48 months or longer.
CBP employs a finite number of trade specialists who handle protests and refund processing. A sudden influx of 300,000 claims would overwhelm existing staff. The agency would need to hire and train new personnel—which requires congressional appropriations that the White House has shown no interest in requesting.
The Federal Budget Constraint
If the Court rules the tariffs unconstitutional tomorrow and orders full refunds, where does $133 billion come from?
Treasury doesn’t have $133 billion in unallocated funds sitting around. The annual federal budget deficit is projected at $1.8 trillion for fiscal year 2025. Revenue from these tariffs has been explicitly counted as an offset in the White House’s fiscal planning. Trump’s budget included revenue projections from these tariffs, assuming approximately $3 trillion over the next decade.
If $133 billion in refunds must be paid out, the annual revenue projections simultaneously drop by that amount going forward. The net fiscal impact is a $133 billion swing in this year’s deficit. The CBO projects this would add approximately $2.2 trillion to long-term deficit projections when accounting for lost revenue over the decade, compounding interest costs, and the need to finance refunds through additional borrowing.
A federal law generally prohibits agencies from spending money Congress hasn’t approved. When the Court struck down steel tariffs in 2003, Congress had to specifically authorize refunds before CBP could process them on a large scale.
The Justice Department has already conceded in filings that if the Court rules the tariffs unlawful, refunds including interest will be issued. But the White House could reverse that position after a ruling, requiring additional litigation to compel refunds.
More likely, the White House could process refunds slowly, stretching the process across multiple fiscal years to avoid a concentrated budget hit. Refunds might be issued on a “pro-rata” basis where each company receives a fraction of its claimed refund each year, with completion delayed until 2028 or 2029. Officials could claim refunds are being processed while containing the annual fiscal impact to manageable levels.
Legal challenges to slow processing would arise, but litigation delays could extend the timeline for full refunds by years.
What the Court Might Do
During oral arguments in November 2025, Justice Amy Coney Barrett asked pointed questions about what remedies would be required. She specifically inquired about how unwinding the tariffs would be “administratively chaotic” and what would happen to companies that missed protest deadlines.
Those questions suggest at least some members of the Court are looking for ways to limit the relief even if they strike down the tariffs themselves.
They have several options. Strike down the tariffs and require full retroactive refunds to everyone who paid, including those who didn’t file protests. That’s the most expansive remedy—and the one that creates a $133 billion fiscal crisis.
Or strike down the tariffs but limit relief to parties who timely filed protests or lawsuits. This would reduce refund obligations by perhaps 20 to 40 percent and would be politically more palatable to the White House.
Or rule the tariffs unconstitutional but decline to order retroactive refunds, only stopping future collections. The $133 billion already collected would stay with the government. This approach has precedent in constitutional tax cases, where the Court has sometimes ruled tax provisions unlawful going forward without ordering refunds of taxes previously paid.
Or order refunds but stay implementation for 90 to 180 days, giving Congress time to enact legislation addressing the revenue shortfall or implementing replacement tariffs under different statutory authority.
The 99-day gap between oral arguments and the current date far exceeds the typical 39 to 67 days for expedited cases. The Court is working through fundamental questions about the proper scope of fair compensation when government exceeds its authority, knowing that their remedy will have massive fiscal and economic consequences.
The Small Business Problem
Beneath the aggregate numbers is a profound equity problem. A small specialty importer—say, a company importing $3 million worth of goods annually—typically lacks an in-house trade compliance department and can’t afford attorneys on staff. When tariffs hit, these companies faced a choice: absorb the costs or hire outside counsel to file protests.
Many absorbed the costs, reduced profit margins to near-zero, and hoped the tariffs would be temporary or that some government program would provide relief.
If the Court strikes down the tariffs, procedural barriers lock these companies out. They didn’t file protests in time. Their entries liquidated. Their deadlines passed. If the remedy is limited to companies that filed protests, these small importers permanently lose their ability to recover costs they paid under what the Court itself ruled was unconstitutional.
Even if the Court orders automatic refunds regardless of protest status, small importers still face administrative hurdles. They need to work through CBP’s procedures, provide documentation of payment, prove import, and respond to agency requests for additional information.
Trade lawyers and brokers note that small business refund claims often disappear into CBP’s administrative processes without receiving priority attention. Costco has teams of trade compliance specialists who track every payment and can produce detailed documentation. A small importer may have only a broker, and if that broker wasn’t specifically tasked with tracking IEEPA payments, reconstructing the necessary documentation becomes nearly impossible.
Refund recovery, even if legally available, will skew heavily toward large importers with sophisticated administrative capacity.
Tariffs on imports are regressive taxes. They hit low-income households harder as a percentage of total expenditure. A tariff on clothing imports disproportionately burdens families with less discretionary income. Small local import businesses in lower-income communities bear costs that large multinational retailers spread across thousands of stores.
If refunds flow primarily to large corporations and bypass small businesses, the distributional injustice of the original tariffs gets compounded rather than remedied.
Retaliatory Tariffs That Won’t Reverse
When Trump imposed tariffs in April 2025, major trading partners responded. China announced retaliatory tariffs reaching 84 percent, then 125 percent on U.S. goods, effectively closing its market to American exports in many categories. The European Union announced retaliatory tariffs on American products from orange juice to automobiles, designed to hit economically sensitive regions.
These retaliatory tariffs remain in place. They don’t automatically reverse because Trump’s original tariffs get struck down.
A corn farmer in Iowa who couldn’t export to China because of Chinese retaliatory tariffs won’t receive government compensation simply because IEEPA tariffs are later ruled unconstitutional. The economic losses to export-oriented sectors have already been incurred. Refunding tariffs to importers does nothing to address this asymmetry.
Officials might attempt to use refund delays as leverage in trade negotiations. Signal to China that refunds will be granted only to companies that maintain supply chain diversification away from China. Tell the EU that refunds come only for companies that agree to surcharges on European products under replacement authority.
Such conditional refund processing would trigger legal challenges on due process grounds, but the litigation would create additional delay.
Timeline for Refund Processing
Based on the extended deliberation and Justice Jackson’s remarks about opinion-writing challenges, most legal analysts expect the decision between mid-February and early April 2026.
Once a decision comes, several procedural steps follow before refunds begin. The decision will be stayed temporarily to allow parties to file motions about implementation. The Court of International Trade, which has stayed approximately 1,000 pending refund cases, will issue guidance about how claims should be processed. CBP will need to issue instructions to field offices about protest resolution, recalculating what companies owe, and refund protocols.
Refund checks will begin going out only after these administrative steps are complete. If the decision comes in mid-February and subsequent steps take 60 to 90 days, refund processing might not begin until May or June 2026 at the earliest.
Importers will have had capital tied up for 12 to 15 months—from February 2025 when tariffs were imposed through May-June 2026 when refunds begin. The opportunity cost of that capital—foregone interest or returns—becomes a permanent loss, regardless of whether tariffs are eventually refunded.
For companies facing cash flow crises, the extended waiting period may be catastrophic. Some smaller importers borrowed money or used credit lines to pay tariffs. Even if refunds are later granted, the interest cost is a permanent loss. Some companies may have already gone bankrupt or been acquired during this period, complicating questions about who has standing to claim refunds.
The Most Likely Outcome
Based on apparent skepticism during oral arguments and the extended deliberation period, the Court will likely rule the IEEPA tariffs unconstitutional but will limit the remedy in ways that reduce the refund obligation.
They might strike down the tariffs as to all future collections but provide refunds only for companies that filed timely protests—reducing refund obligations to perhaps $80 billion to $100 billion. Or they might strike down the tariffs prospectively only, eliminating the refund obligation entirely for past collections.
Under such scenarios, most importers who paid tariffs without filing protests would receive nothing. Large sophisticated importers who hired lawyers and filed protective litigation would recover their payments. The White House could declare victory, arguing the Court vindicated its authority for future policies even if they struck down the current implementation.
Congress wouldn’t face pressure to appropriate refund funds. The deficit would be impacted modestly rather than dramatically. The equity problem would deepen, as large corporations recover their costs while small businesses and consumers bear the burden.
Large importers with legal resources and sophisticated compliance systems will likely recover a substantial portion of their payments, probably within 18 to 36 months of a ruling. Small businesses and consumers will largely absorb the costs of unconstitutional tariffs because they lacked the legal sophistication or resources to file protective claims.
The government will face a significant but manageable fiscal impact, distributed across multiple fiscal years if officials process refunds slowly. International trading partners will maintain retaliatory tariffs against U.S. exports even as tariffs on their goods are refunded, creating a net loss for American exporters that cannot be recouped.
The extended deliberation period compounds these problems with each passing day. Companies burning cash to pay tariffs while waiting for a decision they hope will vindicate their position cannot wait indefinitely. The budget is built on assumptions about revenue that may be invalidated. Supply chains have been restructured on the assumption that tariffs are here to stay, and unwinding those decisions takes time and money.
The refund question isn’t about what the law says and what the Constitution allows. It’s about whether government can be held accountable when it exceeds its authority, and whether citizens who bear the costs of unconstitutional government action can recover their losses.
The answer depends not on what the Court rules, but on administrative capacity, budget politics, and the willingness of the White House to honor refund obligations it has already conceded in filings. Those factors, more than the legal merits, will ultimately determine whether tariffs struck down get refunded to the companies that paid them.
For every additional week the Court deliberates, another $14 billion in tariffs accumulates. The practical reality—who gets money back, when they get it, and what prevents so many from claiming refunds at all—reveals something deeper about how our system works when billions of dollars and constitutional principles collide.
It reveals that procedural sophistication matters more than constitutional rights. That large corporations work through bureaucracy better than small businesses. That fiscal convenience often trumps legal obligation. And that the gap between a favorable ruling and actual relief can be measured in the permanent closure of businesses that couldn’t afford to wait.
