A new two-step authentication for My Tax Account users is now required. We recommend being proactive and registering for this new process prior to the filing or payment due date. 

“The Department of Revenue (DOR) started using Two-step Authentication for My Tax Account (MTA) in early July. MTA users are prompted electronically to provide an email address and/or cell phone number (if text is chosen) to receive a security code for future logins. The next time a user logs into MTA, the user will receive a security code immediately via email or text (based on user choice) to allow entry.”
