Paper 1099 filing checklist: what survives IRS intake

Before you decide to file on paper

• Count every return type together. The ten-return threshold aggregates W-2s, all 1099s, 1042-S, 1098 and the rest. Over ten, paper filing is a penalty per return above the threshold unless a waiver was approved. The waiver, as the IRS decides it.
• Prefer e-filing even under ten. An e-filed return that fails a business rule is rejected back to you with a code. A paper return that fails the same rule is fixed, filled or deleted inside the IRS; only an illegible dollar amount generates a letter (IRM 3.12.8.5(6)).

The payee TIN

• Nine digits, one TIN per box, printed clearly. "A return showing a TIN with other than nine numerics is a no-TIN return" (IRM 3.12.8.3.1). Fewer than nine legible digits, more than nine, an illegible TIN, or two TINs of the same type in the box are all keyed as missing (IRM 3.24.8, Exhibit 2).
• No hyphens problems, but no letters. Hyphens are ignored; a letter or extra character makes it a no-TIN return.
• Never file with a blank TIN as a placeholder. A blank TIN on a filed return is the selection criterion for the backup withholding compliance check, and nobody at intake will notice or fix it: "NEVER replace or enter a TIN obtained through research."
• Sole proprietors: one number. SSN or EIN, not both. Two TINs of the same type in the box become periods, which is no TIN.

The payee name

• TIN owner's name on line 1. The name control is generated from the first four characters of name line 1 and cannot be edited by the examiner (IRM 3.12.8.3.3). A DBA on line 1 with an SSN mismatches.
• Joint names: the TIN holder first. Joint names are split across two lines and only line 1 drives the match.
• Avoid accented characters in the first four letters. They are treated as special characters and replaced with a space (IRM 3.24.8.3.2).
• Do not put "FKA" or "formerly" anywhere. Everything after it is discarded. "DBA" is dropped but the name after it is kept on line 2.
• Legible. An illegible character in a name is keyed as a period and lands in the name control.
• Foreign payees: leave name line 2 empty. The foreign street address is keyed into the second name line field and displaces a c/o or DBA (IRM 3.24.8.3.4).

The amounts

• At least one amount over 99 cents. A return with no significant amount is deleted, and a $0.75 return simply vanishes (IRM 3.12.8.5(5)). Cents are discarded everywhere: "All fields will be dollars only."
• Never file a return whose only amount is box 4 withholding. It is deleted, and the payee cannot claim the withholding from that record (IRM 3.12.8.5(8)(g)). Report the income it was withheld from.
• No negatives in positive-only boxes. They are keyed as zero.
• One amount per box, legible. An illegible or doubled amount is keyed as "?".
• State boxes are not read. State tax and state income boxes are never transcribed from paper for 1099-MISC, NEC, INT, DIV, R or W-2G. File with the state separately.
• Keep withholding proportionate. Withholding at or above 33% of income is routed to fraud review; withholding above the income box is flagged (Exhibit 3.12.8-9, IRM 3.12.8.8).

The payer block and Form 1096

• One payer identity on every page. Any change in payer TIN, name or address is "a change in payer" and can split one submission into several payers (IRM 3.24.8.2.2.1(6)). Same name, same suite abbreviation, same EIN throughout.
• Legible EIN on every page. An indeterminable payer TIN posts as 999999999 and you get no filing credit (IRM 3.12.8.6.7). A missing payer name deletes the whole return.
• No foreign payer address. "Never accept a foreign address for Section 16"; the address fields are deleted (IRM 3.12.8.6(6)).
• Always send Form 1096, one per form type, box 6 checked. No 1096 means the IRS prepares a "Dummy" one flagged as IRS-prepared; an unchecked box 6 posts the batch as 1099-MISC (IRM 3.12.8.2.7, 3.12.8.5.1).
• Box 3 count correct. The 1096 carries the counts the penalty program uses, including "documents subject to penalty."
• Mark CORRECTED only when it is. A corrected return is recognized only from the checkbox, and a corrected return may carry zero amounts while an original may not (IRM 3.12.8.4.3).
• "2nd TIN not." only works on nine forms. 1099-B, DIV, G, INT, K, NEC, MISC, OID and PATR; blanked elsewhere (IRM 3.12.8.4.2).

Mailing and proof

• Certified or registered mail, receipt kept. "Only a registered or certified mail receipt can be used as proof of timely filing" for a penalty response; a plain postage receipt is denied (IRM 4.19.25.8.1(10)).
• Correct IRS address. Mailing to a state agency or the wrong center "does not in itself constitute reasonable cause" (IRM 4.19.25.8(12)).
• Keep a copy of the whole submission. If the IRS deletes a return at intake, your copy plus the certified receipt is the only evidence it was sent.
• Official red-ink Copy A or an approved substitute. Non-standard forms have their box numbers hand-annotated before keying (IRM 3.24.8.3.5(2)); an unprocessable submission draws Letter 1865-C and, if uncured, a format penalty with no 972CG stage (IRM 4.19.25.20).
