NextFin News - Seven months after the Supreme Court ruled most of the Trump administration's sweeping tariffs illegal, the United States has already certified roughly three-quarters of the $166 billion in disputed duties for repayment — about $122 billion sent to the Treasury for disbursement as of September 11, 2026. The money is moving faster than almost anyone expected. The problem is that the quarter still stuck in the pipeline sits in the hardest categories: entries that liquidated long ago, importers with stale bank details, and a legal fight over whether businesses that never sued are entitled to anything at all.
The Scale of the Refund
The scale is unusual for a peacetime tax refund. The Supreme Court's 6-3 decision in Learning Resources, Inc. v. Trump, issued February 20, 2026, held that the International Emergency Economic Powers Act does not authorize the President to impose tariffs. Tariffs, Chief Justice John Roberts wrote for the majority, are taxation reserved to Congress under Article I of the Constitution. The ruling vacated the so-called Liberation Day and fentanyl-related tariffs but did not say how the money should come back. That job fell to the Court of International Trade and, on the ground, to U.S. Customs and Border Protection.
CBP did not build a new agency or mail checks. It built a module inside the trade portal importers already use. The Consolidated Administration and Processing of Entries — CAPE — went live April 20, 2026 inside the Automated Commercial Environment, known as ACE. An importer of record, or its authorized customs broker, uploads a comma-separated file listing eligible entries, up to 9,999 lines per declaration, and can file multiple declarations. CBP strips out the IEEPA tariff codes, reliquidates the entries, consolidates refunds by importer, and pays by ACH direct deposit, generally within 60 to 90 days of acceptance. Paper checks are essentially extinct: a written waiver request is required to receive a Treasury check at all.
The throughput has surprised critics of the process. In the entire prior fiscal year, CBP processed about 338,000 refund entries of any kind. In the first six weeks of CAPE Phase 1 alone, the agency processed IEEPA refunds on nearly 8.5 million entries — roughly 25 times the normal annual pace, according to testimony CBP's trade chief gave at a June 9 hearing. The first ACH payments reached importer bank accounts in mid-May 2026, barely seven weeks after the portal opened.
By June 29, CBP had accepted about $104 billion of claims into CAPE and sent roughly $71 billion to the Treasury. By early August, those figures stood at about $129 billion accepted and $100 billion certified. As of September 11, CBP reported to the Court of International Trade that $134.7 billion had entered CAPE for processing — covering roughly 27.2 million entries — and $122 billion had been certified and sent to the Treasury, about 73 percent of the full pool.
But the easy money is largely gone. What remains is concentrated in the categories that break the assumptions baked into CAPE: entries liquidated more than 80 days before the refund clock started, importers whose ACH banking data has gone stale, and the contested "finally liquidated" pool that the government insists it cannot touch without individual court orders.
The Machine: Why the Refunds Moved So Fast
The refund did not have to be built from scratch, and that is the whole explanation for the speed. ACE already knew every entry, every duty line, and every importer of record. CAPE is not a claims-adjudication system in the ordinary sense — it is a bulk-edit function. When a declaration validates, ACE removes the Chapter 99 IEEPA provision from the entry summary, recalculates the duty, and produces a reliquidation. Because the legal question was binary — the tariff either existed or it did not — there was almost no case-by-case judgment to perform.
The bottleneck was never legal analysis. It was data hygiene and banking enrollment. CBP's guidance is explicit about the failure modes: an importer must have an active ACE portal account and an ACH refund authorization on file; stale routing numbers and lapsed accounts delay payouts. Refunds are also subject to netting against any underpayments on the same entry under 19 C.F.R. § 159.1, and to offset against an importer's "legally fixed and undisputed" debts to the government under 19 C.F.R. § 24.72. A refund can be diverted to pay an unrelated federal debt before the importer ever sees it. CBP has issued repeated fraud warnings — scammers are contacting importers with fake notices and emails — and the agency charges no fee to process a refund.
For small and mid-sized importers without dedicated trade-compliance staff, the administrative burden is itself a tax on recovery. The three-question screen that matters is simple: did you import tangible goods between February 4, 2025 and February 24, 2026; did you pay the new tariffs; and have you filed? If the answer to the third is no, the money is still recoverable for recent entries but the window is closing for older ones.
The Hidden Second Leg: Interest
The payout is larger than the $166 billion principal because the refunds carry interest. Under 19 C.F.R. § 24.36 and 19 U.S.C. § 1505, interest accrues from the date the duty was deposited to the date of refund, at the IRS overpayment rate set quarterly in the Federal Register. For the calendar quarter beginning July 1, 2026, that rate is 7 percent for non-corporations and 6 percent for corporations. Earlier in 2026 the rate ran near 8 percent. Compounded daily over roughly 18 months on duties paid in early 2025, the interest is not a rounding item — it is part of why the certified-to-Treasury figure exceeds the principal collected, and it is the government's bill for holding money it had no legal authority to collect.
There is a second, subtler accounting wrinkle. When a CAPE declaration is accepted, ACE updates the entry summary to a new version, and the refund is consolidated by importer of record — or by the party the importer designates to receive refunds on its behalf through CBP Form 4811, the "notify party" designation — and by liquidation date. That means the cash does not necessarily flow to the entity that wrote the check at the border. A customs broker holding a Form 4811 designation, or a parent company consolidating on behalf of subsidiaries, can be the recipient. For finance teams, the refund can land in an unexpected account, and the accounting entry has to chase the cash.
The Fiscal Hit: Refunds Outrunning Collections
The refund wave has already rewritten the federal budget picture, and this is the second-order effect most readers miss. In May 2026, refunds of customs duties — $21.97 billion — exceeded collections of $21.93 billion. In June the gap widened: $49.1 billion refunded against $23.6 billion collected. Net customs revenue went negative, and the June deficit swelled to roughly $120 billion, a sharp reversal from the $27 billion surplus recorded in June 2025.
The Congressional Budget Office now projects the fiscal 2026 deficit at $2.1 trillion, about $200 billion above its February estimate, citing roughly $250 billion in lower net tariff revenue than previously expected. The tariff program that was supposed to raise revenue ended up widening the deficit, because the refund of past collections hit the books faster than the replacement tariffs could generate new cash. Refunds are booked as negative revenue in the Treasury's monthly statement, so a surge in repayments mechanically subtracts from the top line.
The effect is almost certainly temporary. The refund pool is finite — once the $166 billion plus interest is returned, the outflow stops. But the timing matters for the deficit path: the largest disbursement months landed in the second half of fiscal 2026, front-loading the pain. July saw another $36 billion in refunds, still above the slowed pace of new collections, before the flow begins its descent.
The Stuck Quarter: Finally Liquidated Entries
Here is where the refund machine hits a wall. A meaningful slice of the exposure — the government has estimated more than $30 billion — sits in entries that "finally liquidated," meaning liquidation became final and the 180-day protest window expired before the Supreme Court ever ruled. CBP's position, stated in court filings, is blunt: it has no authority to reliquidate or refund money on finally liquidated entries without a court order, and the Court of International Trade lacks authority to grant universal relief to importers who never sued.
Any liquidated entries for which liquidation is final shall be reliquidated without regard to the IEEPA duties.
That is what Judge Richard Eaton, the senior judge overseeing the refund process, wrote on March 27 — though he continued to suspend immediate compliance. In orders issued July 15 and July 17, he directed CBP to reliquidate and refund IEEPA duties on plaintiffs' finally liquidated entries, indicating the same relief would enter across the roughly 3,700 cases before the court. The government has appealed the broader universal-refund order to the Court of Appeals for the Federal Circuit, challenging whether the trade court can order refunds for importers who did not file their own cases.
The result is a two-tier refund system. Importers who filed protective lawsuits at the Court of International Trade are being pulled through CAPE Phase 3, which launches October 6, 2026 for plaintiffs who submitted their importer-of-record numbers by July 30. Everyone else with finally liquidated entries is in limbo: they cannot use CAPE, and without a lawsuit they may have no path at all.
A class-certification motion now pending before the Court of International Trade could change the picture entirely. If the court certifies a nationwide class of affected importers, CAPE could open to businesses regardless of when their entries liquidated — creating a refund path for those who never filed individual suits. Oral argument was heard in early August 2026, with a ruling pending.
The clock is also running. The trade court's jurisdiction carries a two-year limit, and because the earliest IEEPA entries date to early 2025, the first filing deadlines are expected to begin expiring in early 2027. Importers who take a "wait and see" approach risk losing the right to recover on their oldest entries entirely.
The Reconciliation Trap: AD/CVD and Post-Entry Amendments
Phase 2, which opened June 29, 2026, exposes a different kind of complexity. It covers entries the filer originally flagged for reconciliation — entries filed with incomplete information, such as goods whose value was unknown at entry, or duties paid at the border that were later determined eligible for relief under a free-trade agreement. A final reconciliation entry is filed once the completed information arrives. Roughly 1.6 million reconciliation-flagged entries had been successfully filed in CAPE by June 30.
The trap is narrow but costly: if a final reconciliation entry has already been filed for a flagged entry, that entry may not be entered into CAPE at all. The same logic applies to antidumping and countervailing duty entries, where the final duty rate is not known until the administrative review concludes. For these importers, the refund amount is not a simple function of the IEEPA rate — it depends on a duty calculation that is still in flux, and the CAPE path requires waiting for the underlying review to finish before the IEEPA line can be stripped.
What This Means Next
The central judgment: this is a cyclical liquidity event, not a structural change in trade policy. The money is going back because a court said it was taken without authority, not because the politics of tariffs have changed. Within hours of the February ruling, the administration imposed a 10 percent tariff — raised to 15 percent the following day — under Section 122 of the Trade Act of 1974, a different statute. That surcharge ran its 150-day course and expired July 24, 2026, replaced by a new layer of Section 301 duties. The tariff state is being rebuilt on a different legal foundation, one ruling at a time.
Who benefits and who is exposed. Importers with clean ACE records and unliquidated or recently liquidated entries have already been made whole, with interest. The exposed parties are the ones in the finally-liquidated bucket who never filed protective litigation: if the government prevails on the argument that the trade court cannot order universal relief for non-plaintiffs, that money may never come back. Small and mid-sized importers without trade counsel are disproportionately at risk, because the protective-suit route and the July 30 importer-of-record cutoff for Phase 3 have already passed.
What to watch. Three signals settle the direction. First, the October 6 Phase 3 launch: if CBP processes finally-liquidated claims smoothly for the plaintiff group, pressure builds to extend the path to non-plaintiffs. Second, the Federal Circuit's ruling on the government's appeal of the universal-refund order, and the trade court's decision on class certification. Third, the monthly Treasury statement: once refunds fall below new collections, the deficit distortion reverses.
Scenarios. Base case: most of the $166 billion plus interest is returned by mid-2027, with the finally-liquidated pool resolved through a mix of Phase 3 processing and individual court orders. Upside case: the government concedes broader reliquidation authority, class certification is granted, and the remaining exposure flows through an expanded CAPE. Downside case: the courts side with CBP on universal relief, and a meaningful slice of finally-liquidated refunds is lost to non-litigating importers who missed the two-year window.
The tariff program's legacy is now a ledger entry rather than a policy: the government collected the money, spent it, and is now paying it back with interest. The refund is not a policy reversal — it is a correction of an unauthorized tax. And while the money returns, the tariffs came back under a different statute, which is the real story behind the receipts.
