Quick overview

When a 1099 contains incorrect information — the payee name, TIN, dollar amount, or box entries — the filer (the payer) must correct the information return and furnish a corrected statement to the recipient. Timeliness matters: correct the error as soon as you discover it to avoid mismatches and possible penalties from IRS information-return matching. (See IRS guidance on correcting reported information: https://www.irs.gov/individuals/correcting-information-reported-on-forms-1099-1098.)

Who is responsible for correcting a 1099?

  • Payer (the business or person that issued the original 1099): Primary responsibility to prepare and file a corrected information return with the IRS and send a corrected payee statement to the recipient.
  • Recipient (contractor, vendor, vendor’s representative): Responsible for reviewing all 1099s received and notifying the payer if there’s an error; if a corrected form is not received by the filing deadline, recipients should still report income correctly on their tax return.

In my practice working with small-business clients and independent contractors, most corrections are resolved quickly when the recipient notifies the payer promptly and the payer uses modern e-file systems that support corrections.

Step-by-step guide for payers (filers)

  1. Identify and document the error.
  • Keep supporting records (invoices, bank records, W-9s) that show the correct information.
  1. Prepare the corrected information return.
  • Use the same form type as originally issued (for example, 1099-NEC or 1099-MISC). Do not issue a 1099-C unless you’re reporting cancellation-of-debt income — that is a different form and purpose.
  • On the corrected return, mark the “CORRECTED” box (the box labeled for corrected returns) and enter the corrected data in the appropriate boxes.
  1. Furnish a corrected payee statement.
  • Send the recipient a corrected copy (the payee copy) showing the corrected figures and the correction indicator. Keep proof of mailing or electronic delivery.
  1. File the corrected return with the IRS (and SSA if applicable).
  • If you file on paper, include Form 1096 when required and follow the paper-correction instructions.
  • If you file electronically, use your provider’s correction workflow or the IRS FIRE/e-file correction method and include the correction indicator.
  1. Retain records.
  • Keep copies of the original and corrected returns, proof of delivery, and documentation supporting the correction for at least three years (longer if you suspect fraud or other issues).

For payer filing specifics and correction procedures, see IRS instructions for Form 1099 and the page on correcting information returns (IRS, “Correcting Information Reported on Forms 1099, 1098”): https://www.irs.gov/individuals/correcting-information-reported-on-forms-1099-1098

What recipients should do

  • Compare the 1099 to your own books and bank records immediately upon receipt.
  • If there’s an error, contact the payer in writing (email and a dated letter helps) and request a corrected 1099. Give the payer clear documentation showing the discrepancy (copies of invoices, bank deposits, or a W-9).
  • If a corrected 1099 does not arrive before you must file your tax return, report the income using your records and attach a statement explaining the difference, or include the correct amount on your return and be ready to explain the variance to the IRS if they inquire.
  • If you already filed and later receive a corrected 1099, file an amended return (Form 1040-X) if the correction changes your taxable income or tax liability materially.

Timelines and deadlines you should know

  • Original recipient furnishing deadlines: For most 1099 variants (including 1099-MISC and most other information returns), the payee/copy deadline to furnish to recipients is January 31. For 1099-NEC, the deadline to furnish to the recipient and to file with the IRS is January 31.
  • IRS filing deadlines (original returns): For non-NEC 1099s, the IRS filing deadline is typically February 28 if filing on paper and March 31 if filing electronically; for 1099-NEC it is January 31 (check the current year’s IRS instructions for exact dates).
  • Correct as soon as possible: There’s no special “correction window” that delays the requirement — as soon as an error is discovered, the payer should correct it. If you correct before the IRS begins matching, you reduce the risk of notices or penalties.

Note: Deadlines can be updated by the IRS; always verify the current filing dates in the year you’re filing (IRS, “About Form 1099” and the Form 1099 instructions). (See: https://www.irs.gov/forms-pubs/about-form-1099)

Common correction scenarios and how to handle them

  • Incorrect dollar amount: Issuer files a corrected 1099 with the corrected amount and checks the CORRECTED box. Recipient keeps documentation proving the correct amount.
  • Wrong TIN or SSN: The filer should obtain a corrected W-9 from the payee and issue a corrected return. If the filer previously filed with an incorrect TIN and the IRS sends a TIN mismatch notice, respond with supporting documents promptly to avoid backup withholding or penalties.
  • Wrong payee name: Confirm the correct name and TIN; if both differ, the payer files a corrected form.
  • Wrong form type used originally: If the wrong 1099 variant was used (for example, a 1099-MISC used instead of a 1099-NEC), the payer generally issues a corrected return using the correct form type and follows the correction instructions.

Be careful not to substitute unrelated forms. For example, a 1099-C reports cancellation of debt — do not use a 1099-C to “correct” a reporting dollar amount unless the transaction truly is cancellation of debt.

Electronic vs. paper corrections

  • Electronic corrections: Most modern payroll or accounting software supports marking an information return as corrected and re-filing electronically. Use your software vendor’s guidance or the IRS FIRE/e-file system/process.
  • Paper corrections: Follow the instructions for the specific 1099 you filed — paper corrected returns typically require the CORRECTED box to be checked and may require Form 1096 when filing Copy A by paper.

If you’re an employer or payer who files many information returns, see our payer-focused checklist: Employer Responsibilities for 1099 and 1096 Filings.

Responding to an IRS notice about mismatches

If the IRS sends a notice (often a CP2000-like mismatch letter) saying amounts reported to the IRS don’t match amounts on file, don’t ignore it. You will have a stated deadline to respond. Gather your documentation (contracts, invoices, bank statements, W-9s) and either:

  • Confirm the payer filed a corrected return and provide evidence, or
  • If the payer won’t correct, provide the IRS with your substantiation and a clear explanation.

Our guide on avoiding notices outlines practical steps to reduce audit risk: Correcting W-2 and 1099 Errors Without an Audit.

Penalties and practical risk management

Penalties exist for failure to file correct information returns or to furnish correct payee statements. The IRS adjusts penalty amounts periodically; instead of quoting fixed figures here, review the IRS penalties page and the Form 1099 instructions for current amounts. Acting quickly to correct errors and retaining clear documentation materially reduces exposure.

Practical tips I use with clients: maintain an annual 1099 folder (electronic and physical), standardize W-9 collection up front, and run a pre-filing reconciliation between payee ledgers and the 1099 summary.

Real-world checklist (for payers)

  • Confirm the error and gather supporting documents.
  • Get a corrected W-9 if the payee’s TIN/name is wrong.
  • Prepare corrected 1099 with the CORRECTED box marked.
  • Furnish corrected payee statement and file corrected Copy A with the IRS (and Form 1096 if filing by paper).
  • Keep proof of delivery and records supporting the correction for at least three years.
