TNTAP Login-13 – Third-Party Access to a Client's Account

If you are a tax preparer, you may create a logon on the TNTAP homepage. For security reasons, the Department recommends that the third-party representative never setup access to their client as if he or she is the client. The client/taxpayer does not have to be involved as long as the third-party representative can answer the security questions properly. Additionally, multiple third-party representatives may access one tax account.

When a login is created, use the following steps to gain access to a client’s account.          

  1. Log in to TNTAP.
