Credit card processing and merchant services in Buffalo, NY
Buffalo businesses collect Erie County's 8.75% combined sales tax and follow New York's card-price and cash rules. A second location across the border in Ontario needs its own setup.
Every taxable sale in Buffalo carries 8.75%. That's New York's 4% state rate plus Erie County's 4.75%, the Erie County line in Publication 718, the Department of Taxation and Finance's rate list effective March 1, 2025. Counties set their own local rates, so a second store in another county may need a different number. Monroe County, where Rochester is, sits at 8%.
Two statewide rules decide how you take payment here. A business that surcharges credit cards has to post the total card price, and a percentage on a sign doesn't count. Since March 2026, food stores and retailers across New York also have to accept cash. Our New York page covers both laws with their sources, so we won't repeat them.
Buffalo also sits right on the Canadian border. If you run a shop on the Ontario side as well, that location answers to Canadian rules: a different sales tax, different surcharge rules and Canadian dollars. Don't clone your Buffalo terminal settings for it. We work with businesses in both countries, and our Ontario page covers that side.
The Census Bureau put Buffalo's population at 274,613 on July 1, 2025. For the businesses serving them, the processing rate is usually where the money is. As an example, a restaurant running $45,000 a month through its terminals at a 3.1% effective rate pays $1,395 in fees, and at 2.6% it would pay $1,170, a $225 difference every month.
Interchange-plus pricing shows each of those fees on its own line. Send us one statement for a free statement review and we'll run that math on your real numbers.

Common questions
What sales tax rate do Buffalo businesses charge?
8.75% on taxable sales: New York's 4% state rate plus Erie County's 4.75%. That's the Erie County rate in Publication 718, the Department of Taxation and Finance's rate list effective March 1, 2025. Check the current edition before you open a location in another county.
Can a Buffalo shop go card-only?
Not if it's a food store or a retail establishment. New York's statewide cash-acceptance law has applied since March 2026, with a few narrow exceptions. Our New York page lists them and links the statute, so check it before you take down a cash drawer.
I have a store in Buffalo and one in Ontario. Can one processor handle both?
We work with businesses in the US and Canada, so yes, but each store runs under its own country's rules. The Ontario store charges Canadian sales tax and follows Canada's surcharge rules, and the Buffalo store follows New York's. Our Ontario page has the Canadian details.
Should a Buffalo business surcharge or cut its processing rate first?
Cut the rate first. A New York surcharge can't exceed what the card company charges you, so a lower processing cost also shrinks the most you could surcharge, and it saves money without touching your prices. If you still want a surcharge, the state requires the total card price posted before checkout. A free statement review shows your cost per card.
