One Wrong Name on File Can Hold Back 24% of Your Payouts or Stop Your Container. Check Three Records Before December.

You changed something about your company this year. Maybe the LLC became an S corporation, maybe a holding company now owns the brand, maybe you bought a competitor or moved the warehouse. The name on the tax return changed, or the address did, or the bank account. The records that move your cash did not all change with it.

That used to be a nuisance. This year three of those records picked up a cash penalty, and the penalty lands hardest in the weeks when the most cash is moving.

The three records

Start with the tax form on every sales channel. Every marketplace and payment processor that pays you holds a form with your legal name and tax ID. If they do not match IRS records, the IRS eventually tells the platform, the platform asks you for a corrected form, and if nobody fixes it in time the platform has to withhold 24% of every payout and send it to the IRS. Treasury finalized the rules for marketplace payouts on August 10. Most of the regulation is about when small sellers get caught; a brand your size has been over the line for years. What matters is the size of the haircut. As an illustration only, $1.5 million a month in Amazon payouts becomes $1.14 million. You do get the $360,000 back, as a credit on your 2026 return, which means you see it again in 2027 after the return is filed and processed. December inventory and January payroll do not wait that long.

Second, your importer of record number. Every container you bring in clears customs under an importer number tied to CBP Form 5106: your legal name, physical address, phone, and email. On August 19 CBP announced that from September 18 it would void importer numbers whose 5106 data is inaccurate, "rendering it invalid for any purpose, including entering imported merchandise." That has been in effect for almost two months. The address cannot be a registered agent, a broker, a freight forwarder, a P.O. box, or a business service center. The email and phone must be yours, not your broker's. The notice gives an email address for reinstatement requests and no timeline. A container that cannot be entered sits at the port on the clock, and the goods in it were supposed to be your holiday sales. The notice adds that inaccurate data "could subject the IOR or associated individuals to liability under the False Claims Act."

Third, the bank details on your tariff refund. If you filed for IEEPA refunds, the money may be certified and still not moving. In a court filing dated September 15, CBP reported 20,184 refunds worth about $1.3 billion that had not been sent to Treasury because no bank account information was on file from the importer or its designee on Form 4811. The first reason the same filing gives for refund declarations failing on submission is "importer of record or filer mismatches." Another 6.1 million entries failed entry-level checks, including entries past CBP's 90-day reliquidation window and entries that never carried an IEEPA duty line. The refund itself has been approved. A mismatched record is what keeps it from arriving.

Why this happens after a good year

An entity change is usually a tax decision, and often a good one. A new corporation gets a new EIN. A brand that moves into a holding company now has two names. An acquisition brings in a seller account registered to the previous owner. None of these show up as a problem in the books, because the payouts keep landing and the containers keep clearing until the day a notice arrives at an email address the broker set up.

The one-hour check

Have someone put the legal name, EIN, and physical address from your most recent tax return next to the name and ID on each of these, and note every difference:

1. The tax interview or W-9 on Amazon, Shopify Payments, TikTok Shop, Walmart, PayPal, Stripe, and any other channel that pays you.
2. CBP Form 5106, requested from your customs broker, along with the power of attorney, which CBP says must run directly between you and the broker.
3. The bank enrollment for customs refunds, and who is named on your Form 4811.
4. The borrower name on your line of credit and any UCC filing against your receivables.

Then ask whoever does your books: did any IRS notice about a name or ID mismatch arrive this year, and to which address? Which entity does each 1099-K get issued to, and does that match the entity that reported the sales? Do the 1099-K totals reconcile to the payouts in the books? If that last answer is no, start with the payout reconciliation and the name check will fall out of it.

Where your facts change the answer

An LLC that elects S corporation status keeps its EIN; a newly formed corporation gets a new one. The withholding rules are federal, and states send their own notices. Your customs broker, not CBP's public notice, will tell you what your 5106 says today. None of this is legal advice about an entity change you already made.

If you changed entities this year and nobody has reconciled the names on your payout accounts and customs file to the entity on your return, that is a monthly accounting task to finish this month, before the December payouts land and the January 1099-Ks are issued.
