IRS Publication 1586 – IRS Forms, Instructions, Pubs 2026 – In the complex world of tax compliance, ensuring accurate information returns is crucial for businesses and filers. IRS Publication 1586 serves as a vital resource, outlining reasonable cause regulations and requirements for handling missing or incorrect Name/Taxpayer Identification Numbers (TINs) on information returns. This publication also includes practical instructions for reading CD/DVDs provided by the IRS, which are often used to notify filers of discrepancies. Updated as of July 2023 with references to ongoing inflation adjustments, it helps filers avoid penalties under Internal Revenue Code (IRC) sections 6721 through 6724. Whether you’re a payer filing Forms 1099, W-2, or other information returns, understanding this guide can save you from costly fines—especially with 2026 penalty rates reaching up to $340 per return for late or incorrect filings, or $680 for intentional disregard.
What is IRS Publication 1586 and Its Purpose?
IRS Publication 1586, titled “Reasonable Cause Regulations and Requirements for Missing and Incorrect Name/TINs on Information Returns (Including Instructions for Reading CD/DVDs),” provides essential guidance to prevent penalties for information returns submitted with missing or incorrect TINs. TINs include Social Security Numbers (SSNs), Employer Identification Numbers (EINs), Individual Taxpayer Identification Numbers (ITINs), or Adoption Taxpayer Identification Numbers (ATINs). The publication’s primary objectives are to:
- Offer general information on avoiding penalties under IRC 6721 (failure to file correct returns), 6722 (failure to furnish correct payee statements), and 6723 (failure to comply with other reporting requirements).
- Detail the actions required to solicit TINs from payees.
- Explain how to establish reasonable cause to waive or reduce penalties.
Recent updates include revised penalty rate tables for returns filed on or after January 1, 2024, with annual inflation adjustments referenced in Revenue Procedures. Final regulations for Forms 1095-B and 1095-C were effective in late 2022 and early 2023, impacting health coverage reporting. For filers dealing with specific forms like 1099-S or 1098, additional regulations may apply and could supersede parts of these guidelines.
Establishing Reasonable Cause: Key Regulations
To avoid penalties for missing or incorrect TINs, filers must demonstrate “reasonable cause” under Treasury Regulation 301.6724-1. This requires showing that you acted in a responsible manner both before and after the failure occurred, combined with either significant mitigating factors (e.g., a history of filing accurate returns) or events beyond your control (e.g., payee failure to provide information). Mitigating factors alone aren’t enough; proper TIN solicitations are essential.
Acting responsibly typically involves an initial solicitation at the start of the payee relationship and up to two annual solicitations if needed. Once a valid TIN is obtained, use it for all future filings. Employers can verify SSNs through the Social Security Administration (SSA), though it’s not mandatory. The IRS TIN Matching Program allows pre-filing verification for authorized payers.
A missing TIN is defined as one not provided or clearly invalid (e.g., fewer than nine digits or containing letters). An incorrect TIN fails to match IRS records. Reasonable cause can waive penalties if these criteria are met, but intentional disregard leads to higher fines with no maximum limit.
Requirements for Soliciting TINs: Missing vs. Incorrect
Proper solicitation is the cornerstone of reasonable cause. Here’s a breakdown of general rules for missing and incorrect TINs:
For Missing TINs
- Initial Solicitation: Request the TIN at account opening or relationship start, unless already on file. If not provided, follow up with up to two annual solicitations.
- First Annual Solicitation: By December 31 of the account opening year (or January 31 if opened in December).
- Second Annual Solicitation: By December 31 of the following year if still missing.
For Incorrect TINs
- Initial Solicitation: Same as above. No further action unless notified of an error.
- First Annual Solicitation: By December 31 of the notification year (or January 31 if notified in December).
- Second Annual Solicitation: Only if notified again in subsequent years.
Special rules apply to forms like 1099-R (distributions from pensions), where backup withholding may be required if no response is received. For health coverage forms (1095-B/C), solicitations to the responsible individual cover all parties, and no solicitation is needed for terminated coverage. Exceptions include Form 1098 (annual solicitations until TIN is received), Form 1099-S (initial by closing date), and closed accounts.
For Form W-2, solicit SSNs at hiring via Form W-4 or equivalent, with good faith reliance allowed. Compare payee listings to IRS records and correct discrepancies using Form W-2c if necessary.
Penalty Relief: How to Avoid or Waive Fines
Penalties under IRC 6721 apply for issues like missing TINs, late filings, or incorrect formats, with only the highest penalty per return imposed. As of 2026, rates are tiered:
| Failure Type | Penalty Amount (2026) | |
|---|---|---|
| Corrected within 30 days | $60 per return | |
| Corrected 31 days late to August 1 | $130 per return | |
| After August 1 or not filed | $340 per return | |
| Intentional disregard | $680 per return | Maximum penalties vary: Lower for small businesses (average gross receipts ≤$5 million over three years), with no cap for intentional disregard. De minimis exceptions apply for up to 10 returns (or 0.5% of total) if corrected by August 1. Safe harbor covers errors under $100 ($25 for withholding). |
If you receive Notice 972CG (proposed penalty), respond within 45 days (60 for foreign filers) with a written statement detailing reasonable cause, including solicitations and facts. Include a perjury declaration and signature. IRS may request more details; acceptance comes via Closing Letter 6304C, denial via Letter 854C with appeal options. Federal agencies get Notice 972F without penalties.
Instructions for Reading IRS CD/DVDs
For large volumes (>250 incorrect TINs), the IRS provides data on CD/DVDs. CDs hold up to 750MB; DVDs for larger files. Files include A-Record (payer info, 114 characters), B-Records (payee details, 222 characters each), C-Record (totals, 37 characters), plus Publication 1586 and Form 10301.
Step-by-Step Reading Instructions
- Submit Form 10301 (CD/DVD Encryption Code Authorization) with your company details to the IRS for a PIN (processed in 5 days).
- Insert the media and call 866-455-7438 (or 304-263-8700 internationally) for the encryption code.
- Run the .exe file, enter the code, and extract files to a folder.
- Open .txt files in Notepad, Word, or Excel (use pipe “|” as delimiter; set fields to text to keep leading zeros).
- For databases like Access: Create a new database, import as delimited text (pipe), and set all fields to text.
Understanding record layouts is key—A-Records include payer TIN and counts, B-Records detail payee info and TIN status (1=missing, 2=not issued, 3=incorrect), and C-Records summarize totals.
Conclusion: Staying Compliant with IRS Rules
