JACKSONVILLE, Fla. — A federal grand jury has indicted a Jacksonville Beach dentist on charges of evading personal income taxes, failing to pay employment taxes and attempting to obstruct an IRS investigation, the U.S. Attorney’s Office for the Middle District of Florida announced.
Jon Christopher Williams faces four counts of attempting to evade and defeat individual income taxes, 11 counts of failing to withhold and pay employment taxes, and one count of endeavoring to obstruct and impede the administration of internal revenue laws.
Prosecutors allege that from 2020 through 2023, Williams failed to report roughly $3.37 million in gross income from his dental practice and failed to pay about $1.08 million in taxes owed on that income.

According to the indictment, Williams filed personal income tax returns and paid the associated taxes every year from 2002 through 2012. He requested filing extensions for 2013 and 2014 but never filed returns for those years—or any year since.
The indictment also alleges that while Williams filed employment tax returns and paid associated taxes from 2008 through 2013, he has not filed such returns or paid employment taxes since. From the second quarter of 2020 through the fourth quarter of 2022, he allegedly failed to report and remit approximately $133,360 in employment taxes.
The obstruction charge stems from Williams’ actions after he was served with a summons on Oct. 21, 2021, which made him aware of the IRS criminal investigation.
From November 2021 through May 2024, prosecutors allege Williams sent numerous emails and letters seeking to stop the investigation to the investigating agent and others, including the agent’s supervisor, a Florida member of Congress, Florida’s two U.S. senators, the Treasury secretary, the attorney general, the IRS commissioner and an IRS district director.

The communications included claims that the agent’s actions were causing him “harm, injury and loss,” demands that she “cease and desist” all activity against him, and assertions that she could be held personally liable, according to the office.
The indictment states Williams also sent invoices demanding $525,000 in payment from the agent, the IRS, the Treasury Department and the attorney general, writing that they could “avoid paying the invoices by the immediate termination of [the agent] from her current position of employment, along with her prevention from working at any other agency of the US government.”
He also proposed how the matter could be resolved, writing that “a simple note from you, or your superiors, stating that I, and anyone associated with me, are no longer under investigation and that no further action will be taken against me, my coworkers, or my loved ones, as there is no evidence of any criminal intent to commit a crime, will suffice,” according to the U.S. Attorney’s Office.

The case was investigated by IRS Criminal Investigation and is being prosecuted by Assistant U.S. Attorney Arnold B. Corsmeier.
Court records show that Williams was arrested and arraigned Tuesday—he pled not guilty and has retained an attorney. Williams’ next appearance in federal court is set for September 23rd.
