A former Connecticut tax preparer has pleaded guilty to aiding in the preparation of false tax returns, according to an announcement from David X. Sullivan, United States Attorney for the District of Connecticut, and Thomas Demeo, Acting Special Agent in Charge of IRS Criminal Investigation in New England.
Diana Miller-Lloyd, also known as “Diana Rabin” and “Diana Lloyd,” age 44 and now residing in Jacksonville, Florida, entered her guilty plea on October 1, 2025, at Hartford federal court after waiving her right to be indicted.
Court documents indicate that Miller-Lloyd previously lived in Middlefield and operated Lloyd Forenzique & Accounting Services Corporation. She started this business in Windsor in 2017 before moving it to Branford in 2019 and Guilford in 2021. Prior to 2017, she offered tax preparation services under a different business name. Prosecutors said she regularly obtained large federal tax refunds for clients—many earning more than $500,000 annually—by ignoring information from clients and employers and by making up or improperly claiming deductions for charitable contributions and various business expenses such as advertising, repairs and maintenance, travel, meals, utilities, insurance, and legal services.
From the 2016 through 2021 tax years, Miller-Lloyd attempted to secure at least $1 million in fraudulent refunds or reductions for her clients. The IRS was able to detect some of these fraudulent activities before any refund money was paid out. This led to an actual loss to the government of $472,913.
Prosecutors also stated that Miller-Lloyd sometimes used another person’s professional credentials—a certified public accountant—to defend certain returns during IRS audits.
Miller-Lloyd pleaded guilty to two counts of aiding and assisting in preparing false income tax returns. Each count carries a maximum sentence of three years’ imprisonment. She is currently released on a $25,000 bond pending sentencing scheduled for February 23.
She has agreed to pay restitution of $472,913 to the IRS.
The Internal Revenue Service’s Criminal Investigation Division conducted the investigation. Assistant U.S. Attorney Christopher W. Schmeisser is prosecuting the case.
