IRS TIN Matching

MAG-FILER has added an option to create Bulk TIN Matching files for upload to the IRS e-Services TIN Matching program.  IRS TIN matching can only be used on the following forms – 1099-B, DIV, INT, K, MISC, OID, & PATR. You must be a registered user. Log on to 

To create a file for upload, follow these steps:

  1. Validate Payee names in MAG-FILER.  Payee names can only contain a space, ampersand (&), comma (,) and hyphens (-).
  2. Select the Utilities tab and click TIN Matching then select Create IRS TIN Matching File.  The file created uses the first part of the payer name and MAG-FILER’s assigned Rec#.
  3. MAG-FILER will display the file location for upload and link you to the IRS e-Services site to upload your txt file.  To login manually go to .
  4. You will receive an email from the IRS to check your e-Services Mailbox for your txt file containing matching responses.  You can view your file at the IRS site or download it to your PC. Use a text editor like Notepad to view All Responses in the IRS txt file or you can use MAG-FILER’s Review IRS TIN Matching Results that displays mismatch responses only.
