The $20,000 1099-K Threshold Does Not Apply to Your Merchant Account
The $20,000 1099-K Threshold Was Never About Your Merchant Account
Every article written about the 1099-K threshold in the last year says the same thing. The $600 rule is gone, the number went back to $20,000 and 200 transactions, and small sellers can stop worrying. All of that is true, and none of it applies to a business that accepts cards through a merchant account.
The 1099-K threshold is an exception written for one specific kind of filer. If you take Visa and Mastercard through a merchant account, you are not dealing with that kind of filer, and the exception has never covered you. Your acquiring bank reports your card volume to the IRS whether it is two million dollars or two dollars.
The 1099-K threshold is not new and it has not moved. What it is, is a distinction buried one level below where the coverage stops, and it has quietly caught out merchants who read the headlines and concluded they were now under the reporting line.
The 1099-K Threshold Has Always Had Two Kinds of Filer Underneath It
Section 6050W puts the reporting duty on a payment settlement entity. The IRS instructions split that term into two: a merchant acquiring entity, meaning the bank that has the contractual obligation to pay you for card transactions, and a third party settlement organization, meaning the central organization behind a payment network like an app or a marketplace.
The de minimis exception is written only for the second one. In the instructions it reads that a TPSO is required to report third party network transactions of a payee only if, for the calendar year, the gross amount exceeds $20,000 and the number of such transactions exceeds 200. Both conditions, and only for a TPSO.
No comparable sentence exists for merchant acquirers, so no 1099-K threshold exists for them either. There is no dollar floor, no transaction count, and no de minimis relief anywhere in the payment card half of the form. The IRS said as much in its own guidance after the law changed: a penny of payment card transactions produces a form.
A seasonal or part-time business reads that the 1099-K threshold went back to $20,000, does $9,000 in card sales, and does not expect a 1099-K. One arrives anyway. If the return was already filed without it, the mismatch is what generates the IRS notice — not the tax, the mismatch.
The confusion around the 1099-K threshold is understandable, because the same form covers both lanes and the coverage almost never separates them. It is worth knowing which lane you are in before tax season rather than during it.
The Number on the Form Is Bigger Than the Money You Received
Box 1a reports the gross amount of your reportable transactions. The instructions define gross as the total dollar amount without regard to any adjustments for credits, cash equivalents, discount amounts, fees, refunded amounts, shipping amounts, or any other amounts.
Read that list again, because every item on it is money you did not keep. Your processing fees are in there. Your refunds are in there. Your chargebacks are in there. The form reports what your customers paid, not what your bank account received.
A merchant running $500,000 a year on cards, refunding 2%, and paying a 3% effective rate has a Box 1a of $500,000 and deposits of roughly $475,000. That $25,000 gap is not income anybody is trying to hide — it is fees and refunds, and it belongs on the return as expenses and contra-revenue rather than being quietly subtracted from the top line.
Box 1a minus your actual annual deposits, adjusted for refunds, is close to what card acceptance cost you last year. If you have never been able to find your effective rate on a statement, the tax form gets you most of the way there — and it arrives once a year whether you ask for it or not.
That is the number our effective rate calculator exists to produce, and the reason flat-rate pricing makes it so hard to find directly: a single blended rate on a statement never separates interchange from the processor’s markup. The 1099-K does not separate them either, but it does give you an honest gross to measure against.
Your Card-Not-Present Share Arrives in the Mail Every January
Box 1b reports the gross amount of transactions where the card was not present at the time of the transaction, or where the card number was keyed into the terminal. Online sales, phone sales, and anything typed rather than tapped.
Almost nobody reads it, and it is the single most useful diagnostic on the form. Card-not-present transactions clear at meaningfully higher interchange than card-present ones, so Box 1b divided by Box 1a is the share of your volume sitting in the expensive lane.
If Box 1b is a large share of Box 1a and your staff take cards in person, something is misconfigured rather than unavoidable. A business whose people stand in front of the customer and still clear card-not-present is paying a premium for nothing, and the fix is usually hardware or terminal setup rather than pricing.
That situation is more common than it sounds, particularly where payments are taken inside software that does not support a proper card-present capture. Field service, mobile trades and delivery businesses run into it constantly. Tap to pay on a phone closes the gap without buying terminals, and it moves the same transaction into a cheaper interchange category on day one.
Two New Boxes Land on Restaurants, Salons and Anyone Taking Tips
The December 2026 revision of the form adds Box 1c and Box 1d. Box 1c reports the total cash tips included in Box 1a. Box 1d carries the Treasury Tipped Occupation Code identifying which tipped occupation the tips were earned in, with up to two codes per payee.
Both were added to support the tip provisions in P.L. 119-21. This is the first tax year they appear, which means the forms furnished in January will carry information the previous ones did not, produced from data your processor holds rather than from anything you file.
Box 1c is populated from tip data captured at the point of sale. If your terminal or tip screen is configured in a way that miscategorises tips, that error now travels onto a federal information return rather than staying inside your own reporting. A configuration review costs nothing; a corrected 1099-K costs a conversation with your accountant.
Businesses in restaurants and salons are the obvious population here, but the occupation codes reach further than either category, and the safest assumption is that if your terminal prompts for a tip, these boxes now apply to you.
The Form Tells You How Your Processor Has Classified You
Box 2 carries the four-digit merchant category code the payment card industry uses to classify your business. Your acquirer chose it, usually at boarding, sometimes years ago, and you have probably never seen it written down anywhere else.
It matters because the MCC feeds interchange. Categories carry different rates, some qualify for programs others do not, and a business coded into the wrong category can pay more on every transaction for the life of the account without any line item ever explaining why.
If a payee has receipts under more than one code, the instructions allow the filer to either issue separate forms per code or issue one form using the code matching the largest share of gross receipts. Either way, the code you see in Box 2 is the one your processor has been using — and if it does not describe what you actually sell, that is worth raising.
Three Checks That Take Ten Minutes in January
Once you know the 1099-K threshold does not shield you, the form becomes something to read rather than something to file away. None of this requires a tax professional to start. When the form arrives, three comparisons tell you most of what it can tell you.
Compare Box 1a against your deposits for the year. The gap is fees, refunds and chargebacks, and if it is wider than you expected, the pricing is worth a second look. Compare Box 1b against Box 1a to get your card-not-present share, and ask whether that share reflects how your business actually takes payment. Read Box 2 and confirm the classification matches what you do.
Then reconcile properly. Gross receipts on the return should reflect the gross, with fees taken as an expense and refunds handled as returns rather than netted invisibly. That is ordinary accounting, and the only reason it catches people out is that the form reports a number most merchants have never had to look at directly.
Frequently Asked Questions
No. The de minimis exception restored by P.L. 119-21 applies only to third party settlement organizations, meaning payment apps and marketplaces. Merchant acquiring entities have no threshold, so card volume processed through a merchant account is reported regardless of amount or transaction count.
Box 1a reports gross, defined without regard to adjustments for fees, refunds, credits, discounts or shipping. Processing fees, refunds and chargebacks all sit inside that number, so the form is larger than your deposits by roughly the amount of those items.
Box 1b is reported alongside Box 1a with no 1099-K threshold of its own. It reports the gross amount of transactions where the card was not present or the number was keyed rather than read by the terminal. Dividing it by Box 1a gives your card-not-present share, which is the volume clearing at higher interchange.
Box 1c reports cash tips included in Box 1a and Box 1d carries Treasury Tipped Occupation Codes. Both were added for tax year 2026 under P.L. 119-21 section 70201, and both are populated from tip data captured at your point of sale.
