A Ventura County tax preparer will spend more than two years in federal prison after admitting she filed thousands of fraudulent tax returns. Ann Quach, 50, of Thousand Oaks, was sentenced Friday in Los Angeles federal court.

A decade-long fraud scheme

Federal prosecutors said Quach prepared at least 1,734 inaccurate Form 1040 returns between 2011 and 2024. Many included fabricated losses for fake businesses to lower clients' reported income. Others included false deductions for medical expenses and charitable contributions.

The false claims reduced how much tax clients owed. In some cases, they helped clients obtain refunds. Quach collected substantial fees from those clients, according to the U.S. Attorney's Office for the Central District of California.

Sentencing and restitution

U.S. District Judge Sherilyn Peace Garnett sentenced Quach to 27 months in prison. She also ordered Quach to pay $6,481,731 in restitution. KCLU reported the restitution as roughly $6.4 million.

"Tax fraud is a serious crime that corrodes the foundation of a functional society," prosecutors wrote in a sentencing memorandum. "For years, Quach used her tax expertise to help clients evade tax on their income, causing significant losses to the U.S. Treasury."

Local California context

Quach ran AQ Financial, also known as A2Z Tax Solutions, in Thousand Oaks, a city in Ventura County. The case was handled in the Central District of California, which covers Los Angeles and surrounding counties. The sentence was handed down in Los Angeles.

Background

Tax preparers are required to sign returns and verify information before filing. Fraudulent return preparation can trigger criminal charges, civil penalties, and loss of a preparer's credentials. This case is among the larger local tax fraud prosecutions in the region, though federal authorities regularly pursue preparers who invent deductions or claim fake business losses.

Conclusion

The sentence sends a clear message to tax preparers who break the rules: falsifying returns can lead to prison time and heavy financial penalties. Taxpayers who believe they were affected by Quach's conduct should check their filed returns and consult a licensed tax professional.
