The IRS recently lost a class action lawsuit on how they manage and charge for the Preparer Tax Identification Number (PTIN) program. The IRS PTIN program was updated to include an annual renewal and annual renewal fees several years ago. This was ostensibly to combat tax preparer fraud, yet the IRS was never quite able to articulate how it combated fraud and how much fraud it prevented. The 2014 Loving case is a related case in which the IRS lost the ability to regulate tax preparers.
