The ruling landed quietly, by Supreme Court standards. No dramatic announcement, no press conference, just nine justices and a decision that set off one of the most complicated financial unwindings in modern American trade history. By the time most people read the news on February 20, 2026, the federal government had already collected more than $166 billion from American businesses under a law that the nation’s highest court had just declared was never meant to authorize tariffs in the first place.
For ordinary households, the math had been brutal. Every shopping trip, every online order, every hardware run carried a hidden surcharge that few receipts ever named. The idea that a president could reach into an emergency powers law, one that had sat quietly since 1977, and use it to reshape global trade without a single congressional vote – that idea went before six justices who decided: no, he couldn’t.
What comes next is messier than a headline. Billions in refunds are now owed. New tariffs have already replaced the old ones. And the legal battles over who actually gets paid back, and how much, will stretch well into the future. Here’s what actually happened, what it means for businesses, and what hasn’t changed for your wallet.
What the Trump Tariffs Ruling Actually Said
The Supreme Court held in Learning Resources, Inc. v. Trump that the International Emergency Economic Powers Act (IEEPA), an economic sanctions law, does not authorize the president to unilaterally set tariffs. The decision came down on February 20, 2026, and the vote was 6-3.
The majority opinion was written by Chief Justice John Roberts and joined by Justices Sonia Sotomayor, Elena Kagan, Neil Gorsuch, Amy Coney Barrett, and Ketanji Brown Jackson. Justices Thomas, Kavanaugh, and Alito dissented, concluding that IEEPA does authorize tariffs and that the president acted within delegated authority.
The majority’s core argument came down to one word: “regulate.” The majority held that while the statute authorizes the president to “regulate importation,” it contains no reference to tariffs or duties. Congress has consistently used explicit language when delegating tariff authority and has imposed defined limits on scope, duration, and procedure. In that context, the absence of tariff-specific language in IEEPA was decisive.
The Court noted that these considerations apply with particular force where the purported delegation involves the core congressional power of the purse. In plain terms, taxing is Congress’s job. The Supreme Court concluded that the power to impose tariffs is “very clearly a branch of the taxing power” that Article I, Section 8 of the Constitution vests exclusively in Congress.
How IEEPA Was Used – and Why It Was Controversial from the Start
The case addressed the tariffs President Trump had imposed under IEEPA. The Court affirmed a lower court decision that invalidated two sets of IEEPA tariffs: one set on imports from Canada, Mexico, and China based on declared emergencies concerning illicit drugs, and another set on most other U.S. imports based on a declared emergency concerning the U.S. trade deficit.
Based on that declaration, President Trump invoked IEEPA to announce tariffs of at least 10% on imports from almost all U.S. trading partners, plus higher, country-specific “reciprocal tariffs” for many countries. Canada and Mexico faced 25% tariffs, China faced 10%, and most other nations faced a baseline 10% rate.
The Court found that IEEPA had not previously been relied upon as a basis for imposing tariffs. According to a Congressional Research Service report, the law had never been used this way from its enactment in 1977 until 2025 – nearly five decades during which every president, including those who faced genuine national emergencies, left its tariff potential untouched.
The legal challenges began almost immediately. The U.S. Court of International Trade ruled in May 2025 that the president does not have the authority to use IEEPA to set tariffs, and permanently enjoined the government from enforcing them. That ruling was upheld on appeal by the en banc Federal Circuit Appeals Court in August 2025. The Supreme Court granted review in September, heard oral arguments in November, and issued its final ruling in February 2026.
The $166 Billion Problem
The ruling resolved the legal question cleanly. The financial fallout is anything but.
The scale is unprecedented. Penn-Wharton Budget Model economists estimated that IEEPA-based tariff collections total approximately $175 billion to $179 billion – a figure that exceeds the combined fiscal 2025 spending of the Department of Transportation and the Department of Justice. Had the tariffs been upheld, the Tax Foundation projected they would have raised $1.4 trillion from 2026 through 2035.
The decision definitively resolves only the statutory authority question and does not address the consequences of invalidating the tariffs. The Court issued no directives concerning enforcement, refunds, or other remedial actions, and did not prescribe how its holding should be implemented. The Court left the practical and remedial consequences of its ruling to be addressed in future administrative action or separate judicial proceedings at the lower court – the U.S. Court of International Trade.
That left thousands of businesses in limbo. As of March 2026, over 2,500 individual IEEPA tariff cases were pending before the Court of International Trade, and that number has likely grown substantially.

How the Refund Process Works – and Why It’s Complicated
U.S. Customs and Border Protection developed the Consolidated Administration and Processing of Entries (CAPE) system within the Automated Commercial Environment to streamline the submission and processing of valid refund requests for duties imposed under IEEPA. CAPE is designed to consolidate refunds of IEEPA duties, including interest, rather than processing refunds on an entry-by-entry basis.
The federal government launched the CAPE portal on April 20, 2026, where businesses could file refund requests. The portal briefly crashed when a large number of businesses visited the site after its debut. About $166 billion is estimated to be refunded to more than 300,000 distinct importers to the United States.
Importers and authorized brokers should anticipate that valid IEEPA refunds will generally be issued within 60 to 90 days following acceptance of the CAPE Declaration, unless a compliance concern requires further CBP review.
One critical point that businesses and consumers should understand: CBP is not proactively refunding overpaid IEEPA duties. Businesses have to file a claim through CAPE to receive the refund. The refund process and commercial disputes over which party is entitled to refunds – for example, the importer or the importer’s customer who may have paid a tariff surcharge – are likely to drag on for months or even years, creating additional challenges for some companies.
As of the time of writing, the Trump administration has not raised any further challenge to tariff refunds, but White House National Economic Council director Kevin Hassett said in a Fox News interview that “there’s alternative authorities that perhaps could reduce that number quite a bit,” referring to the size of refunds distributed, according to CNN Business.
The Tariffs That Didn’t Go Away
The ruling was significant. But it wasn’t a clean sweep of all tariffs.
Within hours of the decision, President Trump signed a proclamation imposing a new 10% global tariff under Section 122 of the Trade Act of 1974, effective February 24, 2026. Section 122 contains a hard 150-day statutory limit, meaning these tariffs were set to expire approximately July 24, 2026, unless Congress enacts legislation extending them.
While the Court decided that IEEPA does not provide tariff authority, it did not address tariffs the president may impose under other statutory authorities, including Section 232 and Section 301. Section 232 tariffs – imposed on national security grounds and covering steel, aluminum, semiconductors, and other goods – remain fully in place.
Treasury Secretary Scott Bessent stated that combining Section 122, Section 232, and Section 301 tariffs “will result in virtually unchanged tariff revenue in 2026,” signaling the administration’s resolve to find alternative avenues to reimpose the same levels of duties that were in place under IEEPA.
What This Still Costs the Average Household
The financial pressure on American families hasn’t fully lifted. In 2025, IEEPA and Section 232 tariffs together amounted to an average tax increase of $1,000 per U.S. household. With the IEEPA tariffs struck down and not yet fully replaced, the tax increases in 2026 will be smaller. The Tax Foundation estimates the Section 232 tariffs will create an average tax burden of $600, and the temporary Section 122 tariffs will increase it to $700 for 2026.
Those figures don’t capture everything. In 2026, the tariffs will reduce after-tax incomes for all income groups. The top 1 percent will see a smaller reduction in after-tax income compared to others – a pattern economists describe as regressive, meaning the burden falls hardest on those least able to absorb it.
By March 2026, the administration had announced the start of required investigations on China, Mexico, the EU, and several southeastern Asian countries to establish the basis for tariffs under Section 301. Section 301 tariffs, which target specific countries over trade practices, have their own legal framework entirely separate from IEEPA – meaning the legal fight over tariff authority is far from over.

What This Means for You
The Trump tariffs ruling was a genuine constitutional correction. The Supreme Court’s conclusion was straightforward: one president cannot quietly commandeer a 1977 emergency powers law and use it to impose the largest tax increase in three decades, without Congress ever voting on it. Chief Justice Roberts framed the case around a simple but consequential question – can two words, “regulate” and “importation,” support the president’s claim to impose tariffs of unlimited amount, duration, and scope? The answer from the Court’s majority was no.
For businesses that paid IEEPA tariffs between early 2025 and February 24, 2026, a refund is potentially available – but it requires active filing through the CAPE system at CBP’s official refund portal. The process is not automatic, and eligibility depends on the specific entry dates, HTS codes on your customs forms, and whether your entries fall within the unliquidated or reliquidation window. If you import goods professionally, consulting a licensed customs broker before filing is strongly advised.
For consumers, the picture is more mixed. The Section 232 tariffs on steel, aluminum, and semiconductors remain, as do the Section 301 China tariffs. The temporary Section 122 replacement tariffs are in place through at least mid-summer 2026. The household cost of tariffs has come down from its 2025 peak, but it hasn’t come close to zero – and with multiple ongoing investigations into new Section 301 actions, the trade policy situation remains in motion. Watching what Congress does with the Section 122 expiration deadline, and whether it acts to extend or replace those tariffs, is the next chapter in a story that is very much still being written.
