Payer name-line checker

Enter the filer name lines and TIN type that will go on your Form 1096 or transmitter record and see whether the IRS Payer Master File will post it, correct it silently, or void it, under the rules its unpostable examiners apply.

What the IRS checks on the filer block

The payee names and TINs on a 1099 are matched later, in the TIN Matching program, and produce a CP2100. The filer's own name and TIN are checked first, when the Form 1096 or the electronic transmittal record tries to post to the Payer Master File. A TIN that is not on file unposts as UPC 501; a TIN that is on file with a different name control unposts as UPC 503, reason code 1 (the TIN is an EIN), 2 (an SSN) or 3 (the nine digits exist as both) (IRM 3.12.279.112.1 and 112.2). The rules the tax examiner then applies are the ones this checker tests:

"All business entities (corporations, partnerships, limited liability company's (LLCs), trusts, estates, etc.) must use an EIN as their TIN. The only exception is a sole proprietorship, which may use either a SSN or an EIN as its TIN" (IRM 3.12.279.112(3)). ITINs are allowed for a sole proprietor too (112.1(2) Note).
"For a sole proprietor, the individual name must be entered on the first name line and any business name is entered on the second name line. Sole proprietors may not list their business name first when using either a SSN or an EIN" (IRM 3.12.279.112(3)). The IRM's own examples of a 503 are "the name control used on the unpostable was the first name instead of the last name" and "the name control used on the unpostable was the business name" (112.2(3), rows 4 and 7).
The name control is the first four characters of name line 1 as keyed, never edited (IRM 3.12.8.3.3), so whatever is on line 1 is what gets compared.

What happens if it fails

Nobody writes to you. The examiner researches a better TIN or name control on IDRS and, if the filer can be identified, corrects the record silently (URC 6) and conforms it to what Master File already holds "to prevent repeat unpostables." If the filer cannot be identified, the branch depends on how you filed: with a TCC on the record (an electronic filer) there is no paper to pull, so the record is voided at once (URC D); a paper Form 1096 gets one document request first, then is voided if it does not help (IRM 3.12.279.112.1(2) rows 3 and 4; 112.2(3) rows 6, 10 and 12). A voided record is not reprocessed: the PMF receives new inventory only through cycle 45 and purges what is left after cycle 47 (IRM 3.12.279.112(1)).

What a voided transmittal does downstream is not stated in the IRM. The nearest consequence a payer can see is on the PMFOL screen, where the year's returns may show under the wrong entity or not at all, and in a 972CG for returns it believes were never filed.

The one-line fix

Put the owner's name on line 1 and the business name on line 2, in that order, on every 1096 and in the transmitter and payer records of your filing software. For an EIN, check the name the EIN was established under on the CP 575 or a Letter 147C; that is the name control the IRS will compare. A sole proprietor whose EIN was applied for online may have a name control built from the business name rather than the surname (see the name control page), which is the one case where a business-name line 1 posts and an individual-name line 1 does not.
