The IRS today issued proposed regulations requiring tax preparers to use Preparer Tax Identification Numbers (PTINs) on all tax returns and tax refund claims they prepare.. 

"These regulations allow the IRS to better identify and match tax return preparers with the tax forms they prepare.  This proposed PTIN system will help us  ensure taxpayers receive competent, ethical service from qualified professionals and strengthen the integrity of our tax system," said IRS Commissioner Doug Shulman.

The proposed regulations also provide that tax return preparers must apply for a PTIN, regularly renew the PTIN, and pay associated user fees.  As part of the process, some tax return preparers would also be subject to a tax compliance check, which could include a review of the preparer's history of compliance with personal and business tax filing and payment obligations.

If your preparer does not have a PTIN, you should ask why and consider changing preparers.
