A third Texas tax preparer, Mathews Chacko, has pleaded guilty to conspiring with employees to defraud the United States by filing false federal tax returns for clients between January 2019 and October 2022. Prosecutors say Chacko and his co-conspirators inserted false business expenses on client returns to reduce tax liability and generate improper refunds, sometimes without the clients' knowledge.
Why it matters
This case is the latest development in a federal investigation into a years-long tax refund fraud scheme in Texas. The plea marks the third tax preparer to admit guilt, highlighting the scale and impact of the alleged fraud on the government and taxpayers.
The details
Chacko pleaded guilty to conspiring to defraud the IRS by filing false federal tax returns with fabricated business expenses. This allowed his clients to receive refunds to which they were not entitled. The tax loss attributed to Chacko was more than $3.5 million but less than $9.5 million. Two of Chacko's co-conspirators, Anish Pillai and Mou Kundu, had previously pleaded guilty to their roles in the scheme, causing losses of $1.5 million to $3.5 million, and $250,000 to $550,000, respectively.
