How does Interactive TIN Matching work?

Once you have been established as a user on the TIN Matching system, you will log in with the username and password you established during the registration process. Upon login, users must accept the TIN Matching Terms of Agreement. You will then be prompted to enter a TIN Type, TIN, and Name to be matched against IRS records. You may enter up to 25 TIN/Name combinations during each session. Once you enter “Submit”, the system will return the TIN/Name combinations along with the “Match Indicator” to tell you whether or not the combination matched IRS records. You also have the option of entering each TIN/Name combination individually if you want to do a “Print Screen” and file each printout with the payee’s records in order to establish due diligence.
