Jacksonville Beach Dentist Indicted for Evading Personal Income Taxes, Failing to Pay Employment Taxes, and Attempting to Obstruct IRS Investigation

Jacksonville, Florida - A federal grand jury has returned an indictment charging Jon Christopher Williams with four counts of attempting to evade and defeat individual income taxes, eleven counts of failing to withhold and pay employment taxes, and one count of endeavoring to obstruct and impede the administration of the internal revenue laws. Each tax evasion and employment tax offense carries a maximum penalty of 5 years in federal prison. The obstruction offense carries a maximum penalty of 3 years in prison. United States Attorney Gregory W. Kehoe made the announcement.

According to the indictment, Williams is a dentist with a practice in Jacksonville Beach. He filed a personal income tax return and paid the associated taxes to the IRS every year from 2002 through 2012. He submitted requests to the IRS for extensions of time to file his tax returns for 2013 and 2014, but never filed any returns for those years or for any year thereafter.

The indictment alleges that from 2020 through 2023, Williams failed to report gross income from his business totaling approximately $3,371,657 and that he failed to pay approximately $1,079,136 in taxes due on that income. It is further alleged that Williams filed employment tax returns and paid the associated taxes to the IRS for the years 2008 through 2013, but that he has not filed such a return or paid any employment taxes since 2013. For the period encompassing the second quarter of 2020 through the fourth quarter of 2022, Williams failed to report and pay over to the IRS employment taxes totaling approximately $133,360.

The obstruction charge alleges that Williams became aware that he was being criminally investigated by the IRS when he was served with a summons on October 21, 2021. Wiliams subsequently, over the period of November 2021 through May 2024, sent multiple emails and letters to the investigating agent and others-including the agent's supervisor, a Florida Member of Congress, Florida's two U.S. Senators, the Secretary of the Treasury, the Attorney General, the Commissioner of the IRS, and an IRS District Director-in an attempt to stop the investigation. Among these communications were statements that the agent's actions were causing him "harm, injury and loss," demands that the agent "cease and desist" all activities against him, and statements that the agent could be held personally liable for her actions. Williams sent invoices demanding payment of $525,000 by the agent, the IRS, the Department of the Treasury, and the Attorney General but said 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 stated that, to settle the matter, "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."

An indictment is only an allegation, and every defendant is presumed innocent until proven guilty.

This case was investigated by IRS Criminal Investigation. It will be prosecuted by Assistant United States Attorney Arnold B. Corsmeier.

On April 7, 2026, the Department of Justice announced the creation of the National Fraud Enforcement Division (Fraud Division). The Fraud Division is laser-focused on investigating and prosecuting those who commit fraud against the American people. The Department's work to combat fraud supports President Trump's Task Force to Eliminate Fraud, a whole-of-government effort chaired by Vice President J.D. Vance to eliminate fraud, waste, and abuse within Federal benefit programs.
