The business underreporter program: Letters 2531 and 2030, and how your 1099s are matched to a Form 1120

Who gets matched: 1120 and 1041 only

"The BMF file contains information reported on Form 1120 ... and Form 1041." The Information Returns Master File holds what payers filed, and "a BUR case results when computer analysis detects a discrepancy between the two data sources" (IRM 4.119.4.1.1, 4.119.4.7). Partnerships and S corporations are not worked as underreporter cases; a Form 1065 or 1120-S "with over $500K in gross receipts and there is a mismatch of at least 50% of gross receipt" is routed to Examination instead (Exhibit 4.119.4-3). A BUR contact "is not considered an examination, inspection, or reopening" (Rev. Proc. 2005-32; IRM 4.119.4.1.2), and staff are told to "avoid auditing returns." One EIN, one tax year per case. Case notes "may be viewed by the taxpayer" (IRM 4.119.4.2.2).

What is compared to what

"Consider an IR reported if the taxpayer reports the same amount of income but under a different payer name" (IRM 4.119.4.4.6). And "misplaced entries on the tax return are frequent causes of U/R discrepancies," with "incorrect information from payers" on the same list (IRM 4.119.4.4.5).

The notice sequence and its clocks

The 2531 is required as a first contact when the discrepancy is below a redacted amount, for personal holding company cases, and in certain withholding cases; above it the case can open with a 2030. A response to a 2531 that does not resolve the case produces a 2030, "which allows you additional time to respond." The IRS must reply or send an interim letter within 30 days of receiving a response (IRM 4.119.4.21.1.12), must try one phone call before writing if you gave a number (IRM 4.119.4.21.1), and can accept uploads of up to 15 MB after a call. A corporate proposed deficiency over $100,000 not paid within 30 days of the notice draws two points of additional interest (IRM 4.119.4.16.5).

Which 1099s the examiner deletes first

Before proposing anything, the examiner marks each information return reported, underreported or deleted. Deleted (IRM 4.119.4.4.5): a payee name "obviously not the taxpayer, even though the EIN matches" (unless an obvious owner, the manual's example being a physician and the medical practice); a single return of exactly $999,999,999; returns showing an escrow, "in trust for" or workers' compensation account unless clearly the taxpayer's; and exact duplicates, where "if all elements ... on any two IRs are identical: Including the source, delete one IR. Except the source, delete the paper source." A paper 1099 duplicated by an electronic one loses. Two returns that differ in any element are not duplicates and are both pursued.

Kept despite bad payer data: a payer name "garbled, missing, or incomplete" (the examiner researches the payer TIN), a payee name in a different order, only a name control, a prior name, and foreign-source returns, which "are treated the same as domestic source IRs."

Why a corrected 1099 may not cancel the original

The original is deleted only when the corrected or amended return matches it on payer name and TIN, on account number if one was used, and on income type, or carries "the same money amount and Form 1099-MISC income was amended/corrected with Form 1099-NEC" (IRM 4.119.4.4.5.1). Otherwise: "Pursue all IRs if the amended (or corrected original) does not match an original, or if the amended (or corrected original) IR matches more than one of the other IRs." A payer that corrects a 1099-NEC under a different account number, or re-issues a MISC as an NEC at a different amount, has produced two returns the examiner will add together. A zero-dollar amended return with no amount literals is read as a zero-out. In the response phase examiners are separately told to "consider Amended Information Returns that may be attempts to reduce or zero-out income amounts."

Paper has one more failure mode. "All paper submissions are scanned," and examiners screen for decimal errors (the underreported amount is about 1.111 times the return), commas read as digits ("21230" for 2,123.0), dollar signs read as the digit 5, and duplicated amounts (IRM 4.119.4.4.6.1). A paper 1099 misread at the scanner is a known source of a false notice; the payer's own copy is the evidence.

1099-K is gross, attorney proceeds are ignored

"Gross Payment Card transactions are not adjusted for any authorized returns or other allowances" (IRM 4.119.4.7.3.3). The whole 1099-K amount is treated as unreported unless the taxpayer supplies a breakdown, and a business whose 1099-K duplicates its 1099-NEC or MISC income is asked for processor statements showing "sales tax, fees, cash back, etc." (IRM 4.119.4.21.3.6). Digital-asset 1099-K amounts are valued in dollars at receipt. In the other direction, gross proceeds paid to an attorney (1099-MISC box 10) are never proposed as underreported "UNLESS the taxpayer provides a specific breakdown ... and includes this amount type on their tax return" (IRM 4.119.4.7.3).

What the business sends back

Response forms: Form 15114 with a Letter 2531, Form 15113 with a Letter 2030. Do not send original 1099s; "do not return original Information Return documents" is the instruction to staff. Payment after a statutory notice is not agreement without a signature (IRM 4.119.4.21.8).

When the business blames the payer: Letter 4552C

If the business says a 1099 is wrong and cannot substantiate it, the examiner pulls the payer's address, sends the business Letter 3404C (advance notice of a third-party contact), waits until the 46th day, and sends the payer Letter 4552C asking it to verify (IRM 4.119.4.21.7.5). The payer's reply is monitored for 60 days. If the payer confirms the income, the business gets Letter 4550C with the payer's response attached; if the payer says the income is not the taxpayer's and "the same situation occurred in a subsequent year," the response is filed against the next year too. Once a statutory notice is out there is no time for any of this: the business is told to get the payer's documentation itself and request reconsideration.

Nothing in the letter tells the payer to file a corrected return; it asks for verification. A payer whose 1099 was wrong should correct it anyway, Type 1 or Type 2, and say so in the reply; the CP2000 guide has the mechanics. Systemic payer errors are catalogued on the Payer Agent file, shared with the individual program, but research begins only "when four or more screen prints with the same EIN are identified" (IRM 4.119.4.5.2); an isolated error is never catalogued.

Penalties, and no First Time Abate

Letter 2030 "automatically determines and calculates Accuracy Related Penalties," and a 20% negligence penalty is proposed when the taxpayer "failed to report income reported on a third-party IR for a second tax year" (IRM 4.119.4.16). Reasonable cause is death, illness, disaster, absence or inability to obtain records; "forgetfulness, ignorance of the law, or mistakes (e.g., the taxpayer/preparer forgot to include the income or thought the income was nontaxable) do not qualify" (IRM 4.119.4.16.3.2). "BUR does not grant First Time Abate"; a Form 843 request goes to Accounts Management.
