It’s been a tough week for the IRS.

First, “The Daily Show” host Jon Stewart took the agency out behind the woodshed after it was revealed that nearly two years of e-mails to and from former IRS executive Lois Lerner had disappeared.

“The government agency whose entire business model relies on forcing Americans to live as borderline hoarders only keeps their sh** for six months?” Stewart asks acidly. “You never get a notice from the IRS that says, ‘Please bring your records to us … if you can find them.’”

Watch Stewart’s IRS segment in its entirety … please. 

Then, the morning after Stewart’s blistering commentary aired, the AICPA released a press release that described the IRS’s proposed voluntary certification program for tax return preparers as “unlawful and improper.”

Verbatim:

The AICPA has expressed strong concern that the IRS’s proposed voluntary certification program for tax return preparers “would cause significant legal problems that may ultimately frustrate the IRS’s goals, confuse the public, and lead to litigation.”

In a letter to IRS Commissioner John Koskinen, AICPA Chairman of the Board of Directors William E. (Bill) Balhoff, CPA, CGMA, CFF and President and CEO Barry C. Melancon, CPA, CGMA wrote, “We have repeatedly expressed to you and your colleagues that our members have very significant concerns regarding a voluntary certification program and urged the IRS to have a formal comment period to obtain and consider the public’s views prior to moving forward. … However, it is our understanding that the IRS has no intention of slowing down or considering viable alternatives. Therefore, we feel compelled to consider our next steps, and to raise more formally our legal and policy concerns with the IRS’s current path.”

Yikes.

The ball’s in your court, IRS — and we’re watching.

So is Jon Stewart.
