Here’s the summary from the D.C. Circuit Court of Appeals decision in Loving v. IRS (D.C. Cir. Feb. 11, 2014):

In 2011, responding to concern about the performance of some paid tax-return preparers, the IRS issued new regulations. Among other things, the new regulations require that paid tax-return preparers pass an initial certification exam, pay annual fees, and complete at least 15 hours of continuing education courses each year. The IRS estimates that the new regulations will apply to between 600,000 and 700,000 tax-return preparers.

As statutory authority for the new regulations, the IRS has relied on 31 U.S.C. § 330. Originally enacted in 1884, that statute authorizes the IRS to “regulate the practice of representatives of persons before the Department of the Treasury.” 31 U.S.C. § 330(a)(1). In the first 125 years after the statute’s enactment, the Executive Branch never interpreted the statute to authorize regulation of tax-return preparers. But in 2011, the IRS decided that the statute in fact did authorize regulation of tax-return preparers…. We agree with the District Court that the IRS’s statutory authority under Section 330 cannot be stretched so broadly as to encompass authority to regulate tax-return preparers.

And here’s an excerpt from the conclusion:

It might be that allowing the IRS to regulate tax-return preparers more stringently would be wise as a policy matter. But that is a decision for Congress and the President to make if they wish by enacting new legislation…. The IRS may not unilaterally expand its authority through such an expansive, atextual, and ahistorical reading of Section 330. As the Supreme Court has directed in words that are right on point here, the “fox-in-the-henhouse syndrome is to be avoided … by taking seriously, and applying rigorously, in all cases, statutory limits on agencies’ authority.” City of Arlington v. FCC, 133 S. Ct. 1863, 1874 (2013).
