Due to previously scheduled maintenance on IRS systems, the PTIN system will be unavailable for new applications from 5:00 PM ET on Friday, Dec. 26 until approximately 9:00 AM ET on Monday, Jan. 9. Preparers are still able to renew existing PTINs during this window. We sincerely apologize for the inconvenience. We are exploring ways to mitigate the outage for preparers who cannot meet the December 26 deadline.  More to come on this issue.
