If you sell pottery on Etsy from Taos, drive for a delivery app in Albuquerque, or run a side business through Venmo or PayPal anywhere in New Mexico, the IRS just finished rewriting the rules that decide when your payment platform must report you — and when it must start skimming 24 percent off your gross sales. On August 10, 2026, Treasury and the IRS published final regulations, T.D. 10053, 91 Fed. Reg. 51391 (Aug. 10, 2026), conforming the backup withholding rules under 26 U.S.C. § 3406 to the restored $20,000-and-200-transaction Form 1099-K threshold under 26 U.S.C. § 6050W(e), effective for payments in calendar years beginning after December 31, 2024. The five-year saga behind the rule explains why your platform may have demanded a Form W-9 — and what happens if you ignore it.
What did the IRS’s final backup withholding regulations actually change?
Backup withholding under § 3406 applies only to “reportable payments” — payments a payor must report to the IRS on an information return. The old regulations no longer matched the threshold Congress restored to § 6050W(e) in 2025, so T.D. 10053 amends Treas. Reg. §§ 31.3406(a)-1 and 31.3406(b)(3)-5, adopting January 2026 proposed regulations without change: a payment by a third party settlement organization — the entity behind a payment app or online marketplace — becomes a reportable payment subject to backup withholding only once the payee’s aggregate payments for the calendar year exceed $20,000 and the transaction count exceeds 200.
Two mechanical points matter. First, once a payee crosses the threshold, the crossing payment and every later payment that year are reportable — exposure attaches mid-year. Second, a payee who exceeded the threshold in one year is treated as reportable in the immediately following year regardless of volume: a Farmington eBay reseller with a big 2025 stays in the system for 2026.
How did the 1099-K threshold end up back at $20,000 — and why was your platform asking for a W-9?
Section 6050W was added to the Code in 2008 with a de minimis exception from the start: a third party settlement organization filed Form 1099-K only if the year’s payments exceeded $20,000 and 200 transactions. The American Rescue Plan Act of 2021 (ARPA) cut the trigger to $600 with no transaction minimum, effective for 2022. The predictable result was panic — tens of millions of casual sellers faced 1099-Ks for selling a used couch — and the IRS blinked three times: Notice 2023-10 delayed the $600 threshold for 2022, Notice 2023-74 delayed it again for 2023, and Notice 2024-85 improvised a transition schedule of $5,000 for 2024, $2,500 for 2025, and $600 thereafter.
Congress ended the saga in the One Big Beautiful Bill Act, Pub. L. No. 119-21 (July 4, 2025). Section 70432 restored the $20,000/200 threshold in § 6050W(e) retroactively, as if the ARPA change had never taken effect, and made a companion amendment to § 3406 for payments in calendar years beginning after December 31, 2024. T.D. 10053 is the final administrative step. That history explains platform behavior: while the threshold was headed to $600, platforms began collecting taxpayer identification numbers from nearly everyone — and many have kept those W-9 demands even with the trigger back at $20,000.
What is backup withholding, and how much can the IRS take?
Backup withholding is not a penalty, but it can feel like one. Under § 3406(a), a payor of a reportable payment must withhold tax at “the fourth lowest rate of tax applicable under section 1(c)” — currently 24 percent — when the payee fails to furnish a TIN, furnishes an obviously incorrect one, or when the IRS notifies the payor that the payee’s name and TIN do not match its records. For third party network transactions, § 3406(b) ties reportability to the § 6050W(e) thresholds — precisely what T.D. 10053 implements.
The critical feature is that the 24 percent comes out of gross payments. Backup withholding ignores cost of goods, platform fees, shipping, and rent; it is calculated on the full settlement amount and remitted to the IRS. You recover it as a credit on your income tax return — often a year or more after the cash left your account.
How much could a New Mexico online seller lose to backup withholding?
Consider a Taos potter selling through Etsy who grosses $30,000 across 220 transactions in 2026. She is past both prongs of the § 6050W(e) threshold, so Etsy will file a Form 1099-K. Now suppose she registered under her married name while Social Security records still show her maiden name. The IRS flags the mismatch, Etsy receives a notice, and if it is not cured, Etsy must withhold 24 percent of every settlement. On $30,000 gross, that is $7,200 per year diverted to the IRS — from a business whose actual profit, after clay, glazes, kiln costs, fees, and shipping, might be $12,000. Withholding would consume 60 percent of her real economics, recoverable only after her return processes the following spring. For a seller who depends on the Christmas and summer tourism markets, that cash-flow hit can be existential.
How do you fix a B-notice or TIN mismatch before withholding starts?
When the IRS notifies a payor of a name/TIN mismatch, the payor must send the payee a “B-notice.” A first B-notice can generally be cured with a corrected Form W-9. A second B-notice within three years is stricter: the payee must validate the number at the source — Social Security Administration documentation for an SSN, or IRS Letter 147C for an EIN. The common traps are mundane: a post-marriage name change that never reached the SSA; a single-member LLC’s business name paired with the owner’s SSN in the wrong boxes; an EIN whose IRS name control reflects an old d/b/a. The fix is clerical, but miss the platform’s response window and withholding begins on the next settlement — and does not stop until the cure is processed.
Does the $20,000 threshold mean income below it is tax-free?
No — and this is the most dangerous misreading of the saga. Section 6050W decides when a platform must tell the IRS about you, not when your income becomes taxable. Gross income under 26 U.S.C. § 61 includes gains from selling goods and compensation for services from the first dollar: an Albuquerque handyman paid $14,000 through a payment app owes income and self-employment tax on his profit though no 1099-K will ever issue. New Mexico adds a second layer — the state’s gross receipts tax generally applies regardless of any federal reporting threshold, and the Taxation and Revenue Department runs its own audits. The firm’s New Mexico gross receipts tax audit guide explains how those audits unfold and why marketplace sellers are a frequent target.
The flip side is unfiled-return risk. For every year a platform filed a Form 1099-K, the IRS holds a third-party record of your gross receipts; when no return matches it, the IRS can prepare a substitute for return treating the entire gross amount as profit — no cost of goods, no expenses. The firm’s unfiled tax returns page explains the path back into compliance.
Who still gets a 1099-K below the federal threshold?
The restored trigger is a federal floor for third party settlement organizations — not a universal rule. Several states, including Maryland, Massachusetts, Vermont, and Virginia, require platforms to report at $600; New Mexico has not enacted a lower threshold. Payment card transactions are a separate category entirely: the § 6050W(e) exception covers only third party settlement organizations, so a merchant acquiring bank reporting card swipes — the Santa Fe gallery running Visa transactions through a terminal — reports from the first dollar. Platforms may also file voluntarily below the threshold. The safe assumption for New Mexico sellers: the IRS either knows or can learn your gross receipts, whatever this year’s threshold is.

Frequently Asked Questions
Is money I receive through Venmo or PayPal taxable if I never get a Form 1099-K?
Yes, if it is business or sales income. The 1099-K threshold controls only whether the platform files an information return. Income from selling goods or services is taxable from the first dollar, and New Mexico gross receipts tax applies under its own rules regardless of any federal form.
What is the backup withholding rate in 2026?
24 percent. Section 3406(a) sets the rate at the fourth lowest rate of tax under section 1(c), and it applies to the gross amount of each reportable payment — not to profit after expenses.
Do personal payments between friends count toward the $20,000 threshold?
No. Form 1099-K reporting covers payments settled through third party payment networks for goods and services. Reimbursing a roommate or splitting dinner does not belong in that category, but mislabeled payments can be misreported — keep personal and business accounts separate.
How do I stop backup withholding once a platform starts taking 24 percent?
Cure the underlying problem: respond to the B-notice with a corrected Form W-9, or after a second B-notice, validate your number with Social Security Administration documentation or IRS Letter 147C. Withholding already remitted is recovered as a credit on that year’s return.
Does New Mexico have its own lower 1099-K reporting threshold?
No. New Mexico follows the federal $20,000/200 trigger, but gross receipts tax applies to most sales and services independent of any reporting threshold, and the Taxation and Revenue Department audits online sellers on its own authority.
What if I have unfiled returns for years a platform issued a 1099-K?
The IRS holds the platform’s report of your gross receipts and can prepare a substitute for return treating the full gross amount as taxable profit. Filing accurate original returns with documented expenses is almost always better than fighting a substitute-for-return assessment later.
