Servicios Latinos / Integrity Investments LLC — 12,000 Fraudulent Returns, $5M+ Loss, Vancouver WA (2025)
Outcome: Keith Altamirano, owner of Servicios Latinos (operating as Integrity Investments, LLC) in Vancouver, Washington, pleaded guilty to 16 counts of aiding and assisting in preparing false and fraudulent federal tax returns and was sentenced December 19, 2025 for preparing approximately 12,000 tax returns from 2017 through 2021 that contained systematically fabricated deductions causing over $5 million in losses to the U.S. Treasury.
Servicios Latinos operated as a tax preparation service in Vancouver, Washington, primarily serving the Hispanic community under the Servicios Latinos name (the parent entity was Integrity Investments, LLC). From 2017 through 2021, owner Keith Altamirano prepared approximately 12,000 tax returns that contained fraudulent entries across multiple deduction categories: fabricated medical expenses, invented charitable donation deductions, false vehicle depreciation and expense deductions, and inflated or created business expense deductions.
Two features of the scheme made it particularly serious and deliberate. First, Altamirano used correction fluid (white-out) to conceal alterations on physical return documents — a clear attempt to hide the fraudulent changes from both clients and examiners. Second, he systematically omitted his own name from the tax returns he prepared as a paid preparer, knowing that preparers are legally required to sign returns they prepare for compensation. Omitting his name was a direct attempt to conceal his involvement and avoid detection.
The clients served by Servicios Latinos were generally unaware that their returns contained false information. Altamirano's business grew through word-of-mouth referrals from satisfied clients who received larger-than-expected refunds — an effective recruitment mechanism that insulated him from client complaints while the fraud scaled to 12,000 returns over five years.

How Crucible Prevents This
Crucible's instinct-observer hook would detect the statistical anomaly of a single preparer consistently generating unusually high deductions relative to client income levels across a 12,000-return portfolio. The pre-tool-check hook would require documented preparer identification on all returns before submission. The quality-gate would flag returns where medical expenses, charitable contributions, and vehicle depreciation all appear simultaneously above statistical norms for the client's income bracket.
