Issuers of 1099 Forms must adopt best practices and procedures that streamline both the filing and post-filing process while ensuring accuracy and compliance. Particular attention must be paid to vendor names and taxpayer identification numbers (TINs), as errors in these fields are never considered inconsequential under de minimis error rules. Even minor discrepancies in payee name or TIN information can trigger IRS penalties and unnecessary administrative burdens. Establishing clear internal controls and verification processes is essential to mitigating risk and maintaining reporting accuracy.

This webinar will provide a comprehensive review of proven methodologies designed to reduce errors and avoid penalties. Topics include effective TIN solicitation and verification procedures, timely and appropriate responses to IRS notices, and required steps for issuing and following up on B-Notice letters. Attendees will gain clarity on when and how to implement and discontinue backup withholding, as well as how to manage situations in which vendors fail to provide a TIN or submit incorrect information.

The program will also examine the solicitation process in detail, including the proper use and analysis of Form W-9, annual solicitations, and B-Notices issued in response to IRS notifications. Participants will learn how to register for and utilize the IRS TIN verification service, understand how the system matches names and TINs, and prevent false positive or negative responses. In addition, the webinar will address procedures for submitting TINs for verification, handling mismatches identified by the system, and responding to IRS notifications of proposed penalties for incorrect information returns.

Your Benefits For Attending:
  • Discover best practices and procedures that smooth the filing and post-filing process
  • Learn how to process corrections accurately and efficiently
  • Streamline filing processes to avoid negative interactions with the IRS
  • Discover how to leverage Form W-9 to reduce TIN errors
  • Learn how to process a B-Notice effectively and maintain compliance
  • Gain practical backup withholding strategies for 2026

Attending this webinar will equip you with actionable procedures and compliance-focused strategies to reduce penalties, strengthen internal controls, and confidently manage your organization’s 1099 reporting obligations.

FATCA: FATCA was enacted in 2010 by Congress to target non-compliance by U.S. taxpayers using foreign accounts. FATCA requires foreign financial institutions (FFIs) to report to the IRS information about financial accounts held by U.S. taxpayers, or by foreign entities in which U.S. taxpayers hold a substantial ownership interest. (www.treasury.gov). FACTA (Fair and Accurate Credit Transactions Act) is an amendment to FCRA (Fair Credit Reporting Act ) that was added, primarily, to protect consumers from identity theft.

So, while employers report income that gets paid to employees on Box 1 (Wages, tips, other compensation) of the W2 form, payers report income that gets paid to none-employees on Box 7 (NEC) of the 1099-MISC form. As an individual, if you received form 1099-MISC instead of Form W-2 then the payer did not consider you an employee and did not withhold income tax or social security and Medicare tax.

Form 1099-PATR: File Form 1099-PATR, Taxable Distributions Received From Cooperatives, for each person to whom the cooperative has paid at least $10 in patronage dividends and other distributions described in section 6044(b), or from whom you withheld any federal income tax under the backup withholding rules regardless of the amount of the payment.

Limited Liability Company (LLC): An LLC is a corporate structure where members cannot be held accountable for the company’s debts or liabilities. This can shield business owners from losing their entire life savings if, for example, someone were to sue the company. Can be a single member (much like a sole proprietor) or a multi-member. It shares certain traits of both corporations as well as partnerships or sole proprietorships. It is not a corporation.

Minimum Wage: The lowest wage paid or permitted to be paid specifically fixed by a legal authority or by contract as the least that may be paid either to employed persons generally or to a particular category of employed persons.

Overtime: Overtime is time and a half of what an employee earns for every hour worked over 40 in a workweek. The FLSA salary threshold is the minimum salary employers must pay employees for them to be exempt from overtime wages.

Reasonable Cause : Reasonable cause is based on all the facts and circumstances in your situation. The IRS will consider any reason which establishes that you used all ordinary business care and prudence to meet your federal tax obligations but were nevertheless unable to do so.

Sole Proprietor: A business that legally has no separate existence from its owner. The sole proprietorship is the simplest business form under which one can operate a business. The sole proprietorship is not a legal entity. It simply refers to a person who owns the business and is personally responsible for its debts.

Frequently Asked Questions

A B-Notice is an IRS notification informing a payer that one or more taxpayer identification numbers (TINs) on a filed information return are either missing or do not match IRS records. When you receive a B-Notice, you are required to send a written notice to the affected payee within 15 business days, requesting a corrected Form W-9. This is known as the First B-Notice. If the same payee generates a second mismatch within three calendar years, a Second B-Notice must be issued, requiring the payee to provide IRS certification. Failing to respond to B-Notices properly—or missing the follow-up deadlines—can result in mandatory backup withholding at the current IRS rate. Accounts payable and tax professionals must have clear internal procedures for tracking and responding to B-Notices to stay compliant and avoid penalties.
Backup withholding is a mandatory federal tax withholding applied to certain payments when specific conditions are not met. The most common triggers include a payee failing to provide a valid TIN, a TIN that doesn't match IRS records after a B-Notice, a payee who is notified by the IRS that they are subject to backup withholding due to underreporting, and failure to certify exemption from withholding on Form W-9. Under IRC Section 3406(a), payers must withhold at the backup withholding rate (currently 24%) and remit the withheld amounts to the IRS. Backup withholding applies to payments reported on Forms 1099-MISC, 1099-NEC, 1099-INT, 1099-DIV, and others. Organizations should have proactive TIN validation procedures in place to prevent withholding situations before they arise.
To correct a previously filed 1099, you must issue a corrected Form 1099 clearly marked 'CORRECTED' at the top. The process differs depending on the type of error. For Type 1 errors—incorrect money amounts, codes, or checkbox selections—you file a single corrected return showing the correct information. For Type 2 errors—wrong TIN, wrong payee name, or a return filed for the wrong payee—you must file two separate returns: one to void the original (with a zero amount) and one to issue the corrected information. Corrected forms must also be filed electronically if the original was filed electronically and your volume exceeds the e-filing threshold. Corrected payee copies should be furnished promptly. Staying on top of corrections quickly reduces penalty exposure and helps maintain good standing with vendors and the IRS.
The IRS TIN Matching Program is a free online tool available through the IRS e-Services portal that allows authorized payers to verify that a payee's name and TIN combination matches IRS records before filing an information return. By validating TINs in advance, organizations can dramatically reduce the number of B-Notices received, lower backup withholding exposure, and avoid penalties for incorrect information returns. The system can match TINs interactively (one at a time) or in bulk through a file upload. It's particularly valuable for accounts payable teams onboarding new vendors or conducting annual pre-filing cleanup. However, a match in the TIN system does not guarantee the payee is exempt from backup withholding—it is one tool in a broader compliance strategy that includes proper W-9 solicitation and documentation procedures.
The IRS imposes tiered penalties for filing incorrect or late information returns, including 1099 forms. For returns corrected within 30 days of the due date, the penalty is $60 per return. Returns corrected after 30 days but before August 1 carry a $130 penalty per return. Returns not corrected by August 1, or never filed, carry a penalty of $330 per return. For intentional disregard of filing requirements, the minimum penalty is $660 per return with no annual cap. Importantly, errors in payee name or TIN are never treated as de minimis—making accurate TIN solicitation and validation essential. Attending 1099 compliance training webinars is one of the most efficient ways for tax and AP professionals to stay penalty-free and audit-ready.
