A Vancouver tax preparer, Keith Altamirano, has been sentenced to 18 months in federal prison for defrauding the U.S. Treasury out of over $5 million through the preparation of false and fraudulent tax returns. Altamirano, who operated Integrity Investments, LLC, and did business as 'Servicios Latinos', falsified clients' income tax submissions by listing fake medical expenses, charitable donations, cars, and inflated business expenses. He then omitted his name from the filed returns, resulting in larger refunds for his clients. However, Altamirano's actions were not only financially detrimental but also dangerous. In September 2025, he pleaded guilty to attempted second-degree murder and drug charges in Clark County Superior Court, receiving a concurrent 135-month sentence. Altamirano's fraudulent activities have left his clients at risk of penalties, back taxes, and the stress of being embroiled in his criminal affairs. This case highlights the importance of choosing a reputable and trustworthy tax preparer, and the potential consequences of fraud in the tax industry.
