Six uncompeted federal purchases a year clear $5,000 a month after tax.

Start with the document that moved the line, because it is dated, published and unambiguous. 90 FR 41872, Federal Acquisition Regulation: Inflation Adjustment of Acquisition-Related Thresholds, FAR Case 2024-001, FAC 2025-06, RIN 9000-AO73, published 27 August 2025 and effective 1 October 2025. It raised the micro-purchase threshold from $10,000 to $15,000 and the simplified acquisition threshold from $250,000 to $350,000, using the April 2025 CPI-U value of 320.795 rather than the Councils’ usual March reading. The statute behind it, 41 U.S.C. 1908, requires the adjustment “on October 1 of each year evenly divisible by five.” This is a once-in-five-years event. It happened thirteen months ago, and the next one is 2030.

Now what the ceiling actually removes, which is more than people assume. FAR 13.203(a): micro-purchases “may be awarded without soliciting competitive quotations” where the buyer “considers the price to be reasonable,” and verification is required only where the officer “suspects or has information to indicate that the price may not be reasonable” or where “no comparable pricing information is readily available” — because, the section says, the cost of verifying “may more than offset potential savings from detecting instances of overpricing.” Read the next sentence twice: “To the extent practicable, micro-purchases shall be distributed equitably among qualified suppliers.” The regulation does not merely permit the buyer to spread the money around. It instructs them to.

Then the registration. FAR 4.1102(a) opens with the rule everyone has heard — “Offerors and quoters are required to be registered in SAM at the time an offer or quotation is submitted” — and then lists seven exceptions. The first is “purchases under the micro-purchase threshold that use a Governmentwide commercial purchase card” “as both the purchasing and payment mechanism,” as distinct from “using the purchase card for payment only.” The seventh covers micro-purchases that do not use electronic funds transfer and are not required to be reported. So the single piece of federal paperwork that every guide to government contracting opens with is, in this band, not required of the seller at all.

And then the trap, which is in the same definition as the headline number. FAR 2.101 reads “Micro-purchase threshold means $15,000, except it means — (1) For acquisitions of construction subject to 40 U.S.C. chapter 31, subchapter IV, Wage Rate Requirements (Construction), $2,000; (2) For acquisitions of services subject to 41 U.S.C. chapter 67, Service Contract Labor Standards, $2,500.” The ceiling is therefore 7.5× lower for covered construction and 6× lower for covered services than the figure in every headline about the increase. Those two carve-outs were raised by nothing on 1 October 2025; only the general threshold moved. Whether your work is a covered service decides whether you need 5.25 sales a year or 31.48.

Now the size of the channel. GSA’s SmartPay statistics page reports FY2025 program spend of $39.4 billion, refunds earned by agencies of $471 million, and an average spend of $480 a transaction — which divides out to roughly 82,083,333 transactions in one year. The same page states that purchase card data “is not currently reported into FPDS,” posted on the SmartPay site instead, with an updated FPDS statistics report “to be published in the future.” Set that against the number everybody quotes: the SBA’s FY2025 scorecard, released 25 June 2026, reports $179 billion of prime contracts to small business, nearly 28% of prime dollars. The card channel is 22.01% of that figure, and it is invisible in the database every competitive-intelligence product is built on.

One corner of it is counted, and the counting is instructive. GSA’s Commercial Platforms Program, built under section 846 of the FY2018 NDAA, routes federal micro-purchasing through eight commercial online platforms. Its FY25 highlights print 370k orders, $115M of spend brought under management, an average order size of $326 — “up from $270” — “over $22M in Small business credit,” described as 20% of spend, and nearly 50 participating agencies against 37 the year before. FY24 recorded $96.9M and over $20M of small-business dollars, “100% credited to agencies due to an MOU signed in FY2024 with the Small Business Administration.” Average order size rose 20.74% in a year. The entire programme is 0.29% of SmartPay.

Here is the reading almost nobody holds. The public argument about federal selling is conducted entirely in the language of certification: get into 8(a), get the set-aside, get on a schedule, get the vehicle. In the twelve months to the FY25 scorecard, that door narrowed hard — 8(a) prime dollars fell $1.5 billion to $24.3 billion, “the largest decrease in over 10 years”; approvals ran 2,100 under the prior administration against 65 to date; and nearly 800 firms were put into termination proceedings. In the same twelve months the door that requires no certification, no competition and no registration widened 50%. Nobody wrote that sentence, because the two facts live in different documents and are reported by different trade press.

Which is the whole finding. The scarce input in this band is not a certification and not a contract vehicle; it is being the supplier a cardholder already knows, in a category where the price is obviously reasonable. The arithmetic is unusually kind at the top of the band and unusually cruel at the bottom of it. $5,000 a month after 2026 federal tax is $78,212.05 of profit, which is 5.25 purchases a year at the general ceiling and 241.45 at the only published federal micro-purchase average, $326 — one sale every 1.5 days, forever, at a margin goods do not have. The ceiling is 46.01× the average. Everything about whether this route works is decided by which end of that ratio your invoice sits at.
