Fink has the distinction of playing Mr. Spock in a cheesy but slickly produced "Star Trek" video that IRS employees filmed for the conference.
A total of 132 IRS officials received room upgrades at the conference, according to a report by J. Russell George, the Treasury Department inspector general for tax administration. The tax agency paid a flat daily fee of $135 per hotel room, the report said, but the upgrades were part of a package deal that added to the overall cost of the conference.

The IRS also spent more than $50,000 to produce three videos that were shown at the conference, the report said, including the "Star Trek" parody that featured Fink and other IRS employees.
"The wasteful Anaheim conference is one example of a culture of excess that plagues the IRS and many federal agencies," said Rep. Darrell Issa, R-Calif., chairman of the House oversight committee. "Taxpayer money meant to pay for a core agency mission, the hiring of more enforcement personnel, was instead spent on a lavish party."
Rep. Elijah Cummings of Maryland, the top Democrat on the oversight committee, said IRS spending on conferences, especially the $37.6 million in 2010, was "simply indefensible." But, he added, "I want to make sure we're clear that a lot has already been done to correct the situation."
Werfel took over the IRS last month after President Barack Obama forced the previous acting commissioner to resign following revelations that IRS agents had been improperly targeting conservative political groups when they applied for tax-exempt status during the 2010 and 2012 elections.
The IRS was screening the groups' applications because agents were trying to determine their level of political activity. IRS regulations say tax-exempt social welfare organizations can engage in some political activity but the activity cannot be their primary mission. It is up to the IRS to make that determination.
The revelations about IRS agents improperly targeting tea party and other groups have led to investigations by three congressional committees and the Justice Department. One top IRS official was forced to resign, another retired and a third was placed on paid administrative leave.
"The agency stands ready to confront any problems that occur, hold accountable anyone who acted inappropriately and permanently fix these problems so that such missteps do not occur again," Werfel said.
