Payment App Withholding Below $20,000? Check Last Year’s Payments

A low current-year payment total does not, by itself, establish that a payment platform must stop backup withholding. For covered third-party network transactions, the usual dollar-and-transaction threshold has an important exception when the same payer made reportable payments to the same payee in the preceding calendar year. A separate withholding condition, such as a missing taxpayer identification number, must still exist. Crossing a threshold does not make every seller subject to withholding.

The IRS’s January 8, 2026 announcement introduced proposed regulations published on January 9 to implement changes already made by Congress in July 2025. The January document was a proposal, not a newly effective final regulation. It described the statutory change as applying to calendar years beginning after December 31, 2024, and proposed the same applicability for the regulatory text. Its prior-year exception explains why a seller cannot resolve a withholding question by looking only at this year’s sales dashboard. A separately identified later update below addresses the final regulations.

Identify the Payment and the Reason for the Deduction

This guide concerns payments settled through a third-party network, such as a qualifying marketplace or payment platform. Do not apply that threshold automatically to payment-card transactions, wages, interest, or every payment made by a customer. First ask the payer what kind of transaction it is settling and whether the deduction is federal backup withholding, a platform fee, a commercial reserve, or something else.

Backup withholding currently uses a 24-percent rate when its requirements apply. Failure to provide a correct taxpayer identification number, or TIN, is one possible trigger. A platform’s request for identifying information should not be answered merely with a claim that sales are below $20,000. Conversely, having more than $20,000 in payments does not prove that a valid withholding condition exists. IRS backup-withholding guidance.

The Ordinary Rule Requires Both Limits to Be Exceeded

For the covered third-party network rule, the ordinary threshold requires more than $20,000 and more than 200 transactions in the calendar year. Both conditions matter. Exactly $20,000, or exactly 200 transactions, is not the same as exceeding that limit. The proposed regulation’s first example assumes that the platform properly sought a TIN but the seller did not provide it. The 201st payment takes the total to $20,000.01, and withholding applies to the entire threshold-crossing payment, not just the penny above $20,000. January proposal, 91 Fed. Reg. 934, 935–37.

The general calculation reaches the payment that causes the later of the two limits to be exceeded and subsequent payments that year. It is not a direction to retroactively deduct tax from every earlier payment. But this ordinary threshold analysis is incomplete if the prior-year exception applies.

Last Year’s Reportable Payments Can Change This Year’s Result

The exception concerns one or more reportable payments made by that payer to that payee during the preceding calendar year. It is not simply a test of whether a Form 1099-K happened to arrive. Identify the actual reportable payments and payer/payee relationship rather than treating the receipt or absence of a form as conclusive.

The January proposal illustrates the distinction with future hypothetical years. After the seller’s 2026 payments exceed both limits while the TIN remains missing, the same platform makes only 199 payments totaling $18,000 in 2027. The example still requires backup withholding on each payment because the platform made reportable payments to that seller in the preceding year. In the next example, even four payments totaling $2,000 in 2028 remain subject to that exception. These are illustrations in the rule, not predictions of a particular seller’s business. Id. at 936–37, proposed § 31.3406(b)(3)-5(b)(3)–(4).

The chain does not necessarily end just because volume falls below both limits for one year. The rule’s final example instead uses a year with no payments before a later below-threshold year. That intervening year supplies no reportable payment to carry the exception forward. Do not assume January 1 creates a fresh withholding exemption, or that switching account labels changes the identity of the participating payee. Equally, do not combine unrelated payers without analyzing the actual rule and payment relationships.

Correct the Information Problem Through the Actual Payer

Obtain the payer’s stated reason for withholding and review the tax identity attached to the account. Form W-9 asks for the correct taxpayer name and matching TIN. Its instructions contain specific rules for sole proprietors and disregarded entities; a trade name and the wrong entity’s number can create a mismatch. The form goes to the requester, not directly to the IRS. Use a verified communication channel. Form W-9, pages 1–5.

Form W-9 is for U.S. persons, including qualifying resident aliens. Foreign-person documentation follows different rules. Also distinguish a request to supply missing information from a notice that previously supplied information was incorrect; follow the applicable correction instructions. Do not assume that repeatedly uploading the same form resolves every notice or guarantees immediate release of funds.

Reconcile Withholding Separately From Taxable Income

Keep the payer’s notices, the identifying information submitted, submission confirmations, payment totals and counts for both years, and the amounts actually withheld. Separate federal withholding from fees and reserves when reconciling gross payments with bank deposits. IRS guidance directs taxpayers to report federal income tax withheld under backup-withholding rules on the return for the year the income was received. It is not automatically the final tax due.

The reporting and withholding thresholds do not decide whether income is taxable. A missing Form 1099-K is not an exemption from reporting taxable business income. This federal question also differs from California nonresident service-payment withholding, which involves separate source-income rules and FTB forms.

October Update: The Final Rule Preserved the Exception

Treasury Decision 10053, published and effective August 10, 2026, adopted the proposed rules without change. The final regulations apply to payments made in calendar years beginning after December 31, 2024. The final rule preserved the proposed applicability date. That date is different from the August effective date; neither should be confused with the January proposal date. The operative prior-year exception and examples appear in 91 Fed. Reg. 51391, 51394–95. This later development is included for the October revision, not presented as known on January 10.

For a disputed deduction, bring the actual payer notice and two-year payment history to a review through our tax services practice. The useful question is why these particular payments were treated as reportable and why a withholding condition applied, rather than whether this year’s gross total alone passed $20,000.
