Because dishonest scam artists are STEALING PTINs and filing fraudulent returns. I have had a few clients that I DO NOT WANT having my PTIN or my EFIN. I found a solution--I do not give them a copy of the 8879. My husband worked in account fraud for Bank of America for years. BELIEVE ME there are people who get your information from tax returns when you apply for a loan--NOT CLIENTS--that do dishonest things with personal identification information.

Perhaps you need to go and read IRS Circular 230 again about your duty to AUDIT the returns IRS says YOUR PTIN was used to e-file returns for the year.
