Frequently Asked Questions: Understanding your PTIN-Related Letter

View FAQs for Letters 4810 and 4911

1. Why did I receive a Letter 4743 in the mail about my PTIN account? (posted 7/19/11)

You received the letter as a follow-up security measure to ensure you are aware a PTIN account was created for you. If you believe someone inappropriately created an account on your behalf, contact the IRS Tax Professional PTIN Line to report it. Otherwise, no action is necessary.

2. I received an email telling me to check my Secure Mailbox. What is a Secure Mailbox? (posted 11/9/11)

All online PTIN account holders now have an online secure inbox. This is where we will send you messages about your PTIN. Every time a new message is put in your secure inbox, you will receive a notification at the email address associated with your PTIN account to check your secure inbox.
