C'mon folks, we are talking about a $50 annual PTIN fee here. Most of us make three to five or six times that amount on a single tax return that takes less than an hour of our time. The PTIN does serve a purpose beyond the original one of replacing our SS numbers on signed returns. To some extent it helps the IRS track down dishonest or poorly trained preparers. For example, they now send letters to preparers who have too many errors on EITC, Sch C, and Sch E returns. How do they know who makes too many mistakes? The PTIN. At an IRS liaison meeting the presenter said in routine audits their staff record the PTINs and if the same number keeps popping up they target that preparer's returns. This is how they catch preparers who habitually inflate charitable deductions, employee business expenses, fuel tax credits, education credits, etc. The same unsubstantiated deductions appear on the majority of their returns, which authorities would never have figured out without the PTIN.
What will be another plus is that preparers will be able to monitor the number of returns filed under their PTIN. Currently only EAs can do this, but I was told we were chosen because we were the smallest sample to test the process. Preparers have become the target of identity thieves, so at least we will be able to check if someone is filing returns under our PTINs. I will gladly give up one-fifth of my fee on a single tax return for this protection.
I'm with Lion that the cost of the PTIN is inconsequential compared with the cost of everything else we need. E&O, tax prep software, Quickbooks, etc. seem to go up at a faster rate than we can raise our fees.
