Ecuador's tax authority gave up chasing fake companies and billed the real ones that bought their fake receipts instead

Fake shell companies sell fraudulent receipts so real firms can claim tax deductions for costs that never happened

背景

换别人会怎么做

Find the ghost firms and shut them down — audit the shell company, revoke its registration, prosecute whoever signed the paperwork. It fails because a ghost firm is designed to have nothing to lose: its listed owner is often a stolen identity, a dead person or another shell, and the moment enforcement gets close, the entity dissolves and an equivalent one reopens under a new name days later, so the tax authority spends real effort catching an opponent built to have no assets and no fixed address.

他们看到了什么

A fraudulent transaction always has two parties, and only one of them needs to be real. The ghost firm supplies the false paper trail, but the actual tax benefit — the deduction, the cash saved — lands on its client, a genuine business with real revenue, real assets, real employees and a continuing operation it cannot dissolve overnight the way a shell company can. Chasing the ghost pursues the side of the fraud built to vanish; billing the client pursues the side that, by construction, cannot.

那一手

In 2016, Ecuador's tax authority stopped trying to collect from the ghosts and retroactively targeted their clients instead. Using transaction data it already held, it sent formal notifications to the real, incorporated firms that had claimed deductions from a detected ghost seller between 2010 and 2015, spelling out the exact contested amount ("costs reported by taxpayer" versus "costs calculated by tax administration") and giving each firm 10 business days to file an amended return and pay the resulting tax, interest and fines before the case moved to formal audit.

为什么管用

The tax authority already held third-party transaction data linking specific real firms to specific detected ghost sellers, so it did not need new evidence, only a new target for the enforcement it could already prove. Naming the exact contested figure in the notice removed any room for the client to claim ignorance, and the short deadline pushed the choice from a leisurely dispute into an immediate one: self-correct now at a known, bounded cost, or face a formal audit with added exposure. Because the client firm's business, reputation and future dealings with the same tax authority all continued to exist after the notice — unlike a ghost's — it had something to lose by ignoring the letter and something to preserve by responding to it, which is precisely why over a quarter of firms voluntarily amended returns going back up to six years.

值了多少

Of 2,382 notifications sent to 1,589 firms, 25.4 percent produced a self-filed amendment reducing costs within 90 days — a stark break from the near-zero baseline rate of such amendments before the campaign, timed precisely to each batch of notices going out. Adjusting firms cut their claimed non-labor costs by 98 cents for every dollar the notice contested, netting 72 cents per dollar after firms shuffled some deductions into other cost categories to soften the hit. Total additional tax filed came to $20.6 million — an 81 percent increase over what those same firms had originally reported, and 13.7 percent of all tax reported by every firm that received a notice. The tax authority found no evidence that notified firms went out of business or slipped into the informal sector at any higher rate than un-notified ghost clients, confirming the underlying bet: these firms had real, continuing operations to protect.

什么时候会失灵

The approach depends on the tax authority already possessing verifiable transaction-level records tying specific real clients to specific detected ghosts — without a third-party reporting or e-invoicing system generating that link, there is no client list to notify. It also depends on the client actually being harder to lose than the ghost: against truly small, marginal or already-informal operators with little to protect, the same disappear-and-reopen dynamic that defeats direct enforcement of ghosts could reassert itself. And it recovers only a fraction of what is owed — three-quarters of notified firms did not respond within 90 days, and firms that did respond partially offset the hit by shifting deductions into other cost categories, so the method narrows the loss rather than closing it.

后来呢

Published in the American Economic Review: Insights in December 2023 after circulating as NBER Working Paper 30242, the study frames the $20.6 million recovered as a likely lower bound, since it excludes any VAT amendments the same firms may have also filed and any deterrent effect on firms that were never notified at all. The authors note the enforcement gains were sharply progressive — the additional tax paid, as a share of owner income, ran 56 times higher for the top 5 percent of income earners than the bottom 80 percent, and nearly 170 times higher for the top 1 percent — because ghost-deduction use was itself concentrated among wealthy firm owners to begin with.
