IRS Publication 1335 – In the complex world of tax compliance, understanding backup withholding is essential for payers, payees, and taxpayers alike. IRS Publication 1335, titled “Backup Withholding Questions and Answers,” provides clear guidance on underreporter backup withholding—a mechanism designed to ensure proper reporting and payment of taxes on interest and dividend income. This article breaks down the key elements of the publication, explains its implications, and offers insights into how it affects individuals and businesses. Whether you’re a payer managing accounts or a payee facing withholding, this SEO-optimized overview will help you navigate the rules effectively.
As of February 2026, the latest version of Publication 1335 remains the April 2023 revision, with the IRS website confirming its ongoing relevance through recent page updates. We’ll draw directly from the official document and trusted IRS resources to ensure accuracy.
What Is Backup Withholding and Why Does It Matter?
Backup withholding is a federal income tax withholding process mandated by the Internal Revenue Code (IRC) Section 3406. It requires payers—such as banks, corporations, or other financial institutions—to withhold a portion of certain payments like interest, dividends, or patronage dividends if the payee has underreported income or failed to provide correct taxpayer identification information.
Publication 1335 specifically focuses on underreporter backup withholding, which kicks in when a payee fails to report all their dividend or interest income on their tax return. This is distinct from other forms of backup withholding, such as those triggered by missing or incorrect Taxpayer Identification Numbers (TINs), which are covered in related publications like IRS Publication 1281.
Why is this important? Backup withholding helps the IRS collect taxes upfront, reducing underreporting and ensuring compliance. For payers, non-compliance can lead to penalties, while payees may face unexpected deductions from their earnings. In 2026, the withholding rate stands at 24% for payments made on or after January 1, 2018—a rate that has remained stable despite broader tax changes.
Key Questions and Answers from IRS Publication 1335
The publication is structured as a straightforward Q&A format, addressing common concerns. Below, we’ve summarized and expanded on the most critical sections for better understanding. For the full details, refer to the official PDF on the IRS website.
1. What Triggers Underreporter Backup Withholding?
Underreporter backup withholding occurs when the IRS identifies discrepancies in reported dividend or interest income. The IRS sends at least four notices over 210 days, giving the payee opportunities to correct the issue. If unresolved, the final notice subjects the payee to withholding, and the IRS instructs payers to begin deducting taxes.
Pro Tip: Always update your address with the IRS to avoid missing these notices. If you believe there’s an error, contact the IRS promptly to request a determination letter.
2. Which Payments Are Subject to Backup Withholding?
Not all income is affected. Publication 1335 lists specific payments reported on forms like:
- Form 1099-INT (Interest Income)
- Form 1099-DIV (Dividends and Distributions)
- Form 1099-PATR (Patronage Dividends)
- Form 1099-OID (Original Issue Discount, if paid in cash)
- Other forms including 1099-G (Government Payments), 1099-MISC (Miscellaneous Income), 1099-B (Broker Transactions), and 1099-K (Payment Card Transactions)
Payments under $10 annually are generally exempt, as are salaries, wages, pensions, IRA distributions, and certain “window transactions” like bond redemptions.
3. How Do Payers Implement Backup Withholding?
Payers must obtain an Employer Identification Number (EIN) via Form SS-4 if they don’t have one. Withholding begins on the date payments are credited to the payee’s account, not necessarily when withdrawn. Deposits follow rules in Publication 15 (Circular E), Employer’s Tax Guide.
Payers are required to notify payees within 15 days of the first withheld payment, including details on how to stop it. Withholding continues until the IRS issues a stop notice or the payee provides a post-notice certification.
4. Handling Joint Accounts and Special Cases
For joint accounts, withholding applies if the noticed payee is listed first. If co-owners are named, it extends to all joint accounts or those where either is primary. Deceased payees are generally exempt post-death, as account ownership changes.
If amounts are wrongly withheld, payers can refund them before year-end and adjust deposits accordingly.
5. Reporting and Depositing Withheld Amounts
Use Form 945 (Annual Return of Withheld Federal Income Tax) to report withholdings, and include the amounts on the relevant Form 1099 for the payee. Deposit rules align with those for employment taxes in Publication 15.
Recent Updates and Related Developments in 2026
While Publication 1335’s core content from April 2023 remains applicable, the IRS has issued proposed regulations in January 2026 reflecting changes from the One, Big, Beautiful Bill (OBBB). These updates primarily affect backup withholding thresholds for third-party settlement organizations, reverting to a $20,000 gross amount and 200 transactions threshold for Form 1099-K reporting and withholding. This doesn’t directly alter underreporter rules in Publication 1335 but highlights evolving compliance for gig economy and online payments.
For the most current information, always check the IRS website, as pages related to backup withholding were last reviewed in February 2026.
How to Stop or Avoid Backup Withholding?
If you’re subject to withholding, resolve the underreporting by filing amended returns or responding to IRS notices. Obtain a determination letter from the IRS to certify you’re no longer liable. Payers must honor this certification issued after the start notice.
Prevention is key: Accurately report all income, provide correct TINs, and respond to IRS correspondence promptly.
