Middlefield Tax Preparer — and Self-Described Fraud-Forensics Specialist — Accused of Stealing Over Half a Million in Client Refunds
A federal tax case with deep Connecticut roots has taken another turn as Diana Miller-Lloyd, who once marketed herself on LinkedIn as certified in fraud forensics, has pleaded guilty to preparing false tax returns while operating her Middlefield-area tax businesses. Miller-Lloyd, 44, now living in Jacksonville, Florida, appeared in Hartford federal court on October 1, 2025, where she waived indictment and admitted to aiding in the preparation of fraudulent federal returns.
Court records describe a years-long pattern spanning multiple towns and multiple business names. Miller-Lloyd, who previously lived in Middlefield, launched Lloyd Forenzique & Accounting Services Corporation in Windsor in 2017 before relocating it to Branford in 2019 and then to Guilford in 2021. Even before that, she prepared returns under the name Lloyd Forensic & Accounting Services. Throughout this period, prosecutors say she routinely secured outsized federal refunds for clients—many earning more than $500,000 a year—not by following the information they or their employers provided, but by fabricating deductions and inflating expenses to create losses that didn’t exist. Among the false entries were charitable contributions, travel, meals, advertising, utilities, repairs, insurance and legal services.
From 2016 through 2021, these manufactured deductions helped her attempt to claim at least $1,062,293 in fraudulent refunds or reductions of tax debts. The IRS detected irregularities on a number of the returns before the refunds were paid out, but investigators still calculate the government’s actual loss at $472,913. Adding to the deception, prosecutors say Miller-Lloyd sometimes used another person’s CPA credentials to defend the returns during IRS audits.
She pleaded guilty to two counts of aiding and assisting in the preparation of false and fraudulent income tax returns, each carrying a maximum three-year federal prison sentence. She is currently free on a $25,000 bond while awaiting sentencing on February 23 and has agreed to repay the IRS $472,913 in restitution.
The case was investigated by the IRS Criminal Investigation Division and is being prosecuted by Assistant U.S. Attorney Christopher W. Schmeisser. As the legal process moves forward, it remains a striking twist that someone who publicly presented herself as trained in fraud forensics now stands convicted of the very conduct such training is meant to uncover.
As always, the defendant is presumed innocent of any additional or uncharged misconduct unless proven guilty in court.
