Acting Internal Revenue Service Commissioner Danny Werfel said he placed the staffers on administrative leave for receiving the food and gifts at a private party in Anaheim, California, where IRS managers were attending a 2010 conference.
"When I came to IRS, part of my job was to hold people accountable," Werfel said in a statement. "There was clearly inappropriate behavior involved in this situation, and immediate action is needed."
The IRS said it has begun the process of removing the employees "pending further review."
A report by Buzzfeed said Schindler and a second staffer were put on leave for accepting USD1,162 in free food and gifts provided by an event planner during an "after hours" party in Anaheim.

Other media outlets identified the second staffer as Donald Koda, who also works on implementing the health care law.
On Tuesday, the Treasury's inspector general for tax administration released a report on the 2010 conference attended by 2,600 people, for which it said the IRS spent at least USD 4.1 million.
Some USD 64,000 were also spent on gifts and souvenirs for participants, according to the report.
"The wasteful Anaheim conference is one example of a culture of excess that plagues the IRS and many federal agencies," said House Oversight and Government Reform Committee Chairman Darrell Issa, a persistent critic of the Obama administration.
The revelation is the latest black eye for an agency that last month admitted its agents inappropriately targeted conservative groups applying for non-profit status.
