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.

What happens if I submit just the TIN or the name? Will IRS provide the correct name or TIN that is associated with the information I submit?

You must submit a TIN/Name combination. If you leave either the TIN or name blank, the system will consider it invalid (Indicator 4). Due to privacy issues, IRS will not divulge an entity’s name or TIN.

If you submit the same TIN with various names, or, the same name with various TINs, after four attempts, the system will automatically suspend your access to TIN Matching for 96 hours. This was done to prevent “phishing”.

Is there a limit to the number of bulk files I can upload each day?

No. There is currently no limit. Once the system has been fully implemented, and there are many users logged in, the time it takes to upload files may slow somewhat. At this time, e-Services does not plan to restrict the number of file uploads per day for any user.

When naming your .txt file, do not use special characters in the file name. Type the file name in plain fonts, (Courier works best), and place the dot extension directly before the file name extension. Example, a file named TIN Match Vol2 should be saved as TIN Match Vol2.txt. Unacceptable file names, such as TIN.Match.Vol2.txt or TIN_Match_Vol2.txt, may cause your file to be rejected by the system.
