The Treasury Department and Internal Revenue Service finalized regulations governing backup withholding on third-party network payments. The action matters to payment organizations and participating payees because it aligns the withholding rules with the statutory Form 1099-K reporting threshold.
Key Facts
- The final regulations took effect August 10, 2026.
- They apply to payments made in calendar years beginning after December 31, 2024.
- A payee generally must exceed both $20,000 in aggregate payments and 200 transactions before the threshold condition is met.
- Crossing both thresholds does not by itself require withholding.
What the final rule changes
Backup withholding requires a payer to withhold federal income tax from certain reportable payments when a separate condition in the tax code exists. One example is a payee’s failure to provide a required taxpayer identification number.
For third-party network transactions, the regulations generally treat payments as reportable for backup-withholding purposes only after both annual thresholds are exceeded. Aggregate payments to the participating payee must exceed $20,000, and the number of transactions must exceed 200.
The transaction that crosses the later threshold is included in the amount subject to withholding. Later covered transactions during that calendar year are also included if a separate backup-withholding condition applies.
The rule also carries out a prior-year provision enacted by Congress. The threshold limitation does not apply in the current year when the payer made a reportable third-party network payment to that payee in the preceding year.
What the rule does not mean
Exceeding the payment and transaction thresholds does not automatically trigger backup withholding. A separate condition under Section 3406 of the Internal Revenue Code must also exist.
The thresholds also do not decide whether money received through a payment network is taxable. Treasury and the IRS said taxability and income-reporting duties do not depend on receiving a Form 1099-K or having backup withholding applied.

Congress set the underlying threshold
The agencies did not create the $20,000-and-200-transaction test in this final rule. Congress enacted the underlying change in Section 70432 of Public Law 119-21 in July 2025.
Treasury and the IRS proposed conforming regulations in January 2026. The final rule says the agencies received eight comments and adopted the proposal without change.
No public hearing was requested or held.
How the agencies addressed comments
One commenter sought prospective-only application. The agencies declined that request because Congress made the statutory amendment applicable to calendar years beginning after December 31, 2024.
Three commenters said the proposal was confusing or could be clearer. The agencies made no change, noting that the commenters did not offer replacement language and that the regulations implement the statutory amendment.
Other comments sought added enforcement explanations, broader exemptions, administrative review and a $200,000-and-10,000-transaction threshold. Treasury and the IRS said those requests were outside the rule’s scope or beyond their authority.
When the rule applies
The final regulations became effective when published on August 10, 2026. Their applicability reaches covered payments made in calendar years beginning after December 31, 2024.
The action completes this notice-and-comment rulemaking. The final record does not set another comment deadline or a public hearing.
