The Trump Administration Can’t Process Tariff Refunds Because Its Computers Are Too Old

The Trump administration has admitted it literally cannot process refund payments owed to importers who overpaid on tariffs — because the government’s computer systems aren’t up to the task. Not a policy decision. Not a legal dispute. A technology failure.

According to reporting from Reuters and discussion on Slashdot, U.S. Customs and Border Protection (CBP) has told importers and trade brokers that its outdated IT infrastructure cannot handle the volume and complexity of refund calculations triggered by the administration’s rapidly shifting tariff regime. The agency processes tariff payments through the Automated Commercial Environment (ACE), a system that has been incrementally modernized over the years but still relies on aging backend architecture that was never designed for this kind of whiplash policymaking.

Here’s what happened. The Trump administration has imposed, adjusted, paused, reimposed, and recalculated tariffs on goods from multiple countries at a dizzying pace throughout 2025 and into 2026. Each change creates a cascading set of obligations — and in many cases, overpayments by importers who paid duties at one rate before that rate was lowered or temporarily suspended. Those importers are owed refunds. CBP says it can’t deliver them right now.

The problem isn’t trivial. We’re talking about potentially billions of dollars in refunds that American businesses are owed but cannot access. For small and mid-sized importers operating on thin margins, delayed refunds aren’t an inconvenience — they’re a cash flow crisis. And the administration’s response so far has been to acknowledge the problem exists without offering a clear timeline for resolution.

Trade professionals have been flagging ACE’s limitations for years. The system was originally conceived in the early 2000s as a replacement for the even older Automated Commercial System, which dated back to the 1980s. ACE went through a long, troubled development process and wasn’t fully deployed until 2016. But “fully deployed” is generous. The system has been criticized by the Government Accountability Office and by trade industry groups for its rigidity, its difficulty handling retroactive rate changes, and its poor integration with other federal agency systems.

So when tariff policy started changing on a near-weekly basis, ACE buckled. It’s not that the system crashed — it’s that the logic required to recalculate duties retroactively across thousands of tariff lines, for hundreds of thousands of entries, exceeds what the system was built to do efficiently. Or at all, apparently.

This matters for several reasons beyond the immediate financial pain for importers. It exposes a fundamental tension in the administration’s trade strategy: you can’t run an aggressive, fast-moving tariff policy on infrastructure designed for a more stable trade environment. The technology has to match the ambition. Right now, it doesn’t come close.

CBP has reportedly told customs brokers that manual workarounds are being explored, but anyone who’s dealt with government manual processing knows what that means. Delays measured in months, not weeks. Errors. Inconsistencies between ports of entry. The kind of friction that makes doing business with the United States measurably harder.

Industry groups are not happy. The National Customs Brokers & Forwarders Association of America has raised concerns about the refund backlog, and trade lawyers have been increasingly vocal about the downstream effects on their clients. Some importers have reportedly begun factoring the possibility of never receiving their refunds into their financial planning — essentially writing off money the government owes them.

And this isn’t happening in isolation. The administration has also faced criticism for the broader chaos surrounding its tariff implementation. Rates have changed so frequently that compliance teams at major corporations have struggled to keep up, and smaller businesses without dedicated trade departments have been left guessing. Adding a technology failure on top of policy unpredictability creates a compounding effect that erodes trust in the system itself.

The IT modernization question is a familiar one in Washington. Federal technology infrastructure is notoriously outdated across agencies — the IRS still runs systems built on COBOL, the Social Security Administration has similar legacy issues, and the Department of Defense has spent decades and billions trying to modernize procurement systems. But the CBP situation is uniquely acute because it sits at the intersection of real-time policy changes and real-time financial obligations. When the IRS is slow, your refund takes an extra month. When CBP can’t process refunds, businesses bleed cash.

There’s no indication that Congress is moving quickly to address the underlying technology gap. Appropriations for CBP IT modernization have been modest relative to the scale of the problem, and the current political focus on tariffs as a policy tool makes it unlikely that anyone in the administration wants to draw attention to the fact that the machinery behind that policy is broken.

But broken it is. The administration has effectively created obligations it cannot fulfill, not because of legal constraints or budget limitations, but because the computers won’t cooperate. That’s an extraordinary admission from any government, and it should alarm anyone whose business depends on predictable trade operations with the United States.

For industry professionals watching this unfold, the practical advice is blunt: don’t count on timely refunds. Build the delay into your cost models. Talk to your customs broker about the specific status of your entries. And if you’re lobbying anyone in Washington, maybe add CBP systems funding to the ask list. Because this problem isn’t going away on its own.
