Vancouver tax preparer Keith Altamirano, 52, received an 18-month federal prison sentence for preparing false and fraudulent tax returns, according to a news release from the U.S. Attorney’s Office for the Western District of Washington on Dec. 19.
Altamirano pleaded guilty to 16 counts of aiding and assisting in the preparation of false tax returns. From 2017 to 2021, he operated Integrity Investments LLC, doing business as Servicios Latinos, and prepared approximately 12,000 tax returns. A statistical analysis estimated his fraudulent practices caused more than $5 million in losses to the U.S. Treasury, the release stated.
Court records show Altamirano falsified client returns by listing fabricated medical expenses, charitable donations, vehicle depreciation and inflated business expenses. Prosecutors said clients did not know about the fraud and believed Altamirano prepared their returns legally.
The court ordered Altamirano to pay $104,518 in restitution to the Internal Revenue Service and to sell one of his properties to satisfy the payment.
In a separate case, Altamirano pleaded guilty in September 2025 to attempted second-degree murder and drug charges in Clark County Superior Court. The court sentenced him to 135 months in state prison, to be served concurrently with his federal sentence.
IRS Criminal Investigation led the investigation into the tax fraud case.
