Matercard Specialty Merchant Registration Fee Increased June 3!
June is when this turns from “noted” to “felt” for acquirers and high-risk ISOs.
Mastercard already doubled the annual Specialty Merchant Registration fee on May 1, and yesterday (on June 3) the next layer kicked in: additional transaction and volume-based fees. If your merchant or ISO agreements are silent on pass-through, that silence is about to hit margin.

What's changing.
Mastercard has updated the Specialty Merchant Registration Program effective May 1, 2026 across AP, LAC, and US regions. The annual registration fee moves from $500 to $1,000 per merchant (per the Fiserv Spring 2026 Card Brand Updates and PayPal Spring 2026 Release Guide).
Mastercard is also introducing additional Specialty Merchant transaction and volume fees, including a $0.02 per purchase transaction fee and a 10 basis point volume-based fee on certain specialty categories took effect June 3.
Published processor notices identify categories including non-face-to-face adult content, gambling, pharmaceutical, tobacco, lottery, skill games, high-risk cyberlockers, high-risk securities, cryptocurrency, certain negative-option physical product sales, and other specialty merchant categories.
Where the exposure lives.
Many specialty merchant agreements were drafted when $500 was less material. They're silent on pass-through, or they use generic "network fees" language without naming this one specifically. At $1,000 annual plus the June 3 volume and transaction add-ons, that silence becomes a real margin item.
The pattern I've seen. Acquirer and ISO finance teams may have absorbed the $500 fee for years because the merchant conversation wasn't worth the friction. At $1,000 plus the June layer, the math flips. On a 500-merchant specialty book, the registration delta alone is a quarter-million in annual cost depending on which way you handle it.
If you're absorbing the May 1 registration, you're setting precedent for absorbing the June 3 volume and transaction fees too. The conversation is easier to open now than after both layers are in flight. This week. Pull your top 20 specialty merchant agreements. Search the language for "registration," "high-risk," "Mastercard fees," “network fees," and "pass-through." Where the language is silent or ambiguous, decide now whether you absorb or open the conversation with the merchant. Document the decision per account.
Happy to compare notes if you want a second set of eyes on contract language before the next invoice cycle reflects both layers.
