Credit card processing and merchant services in New Haven, CT
New Haven restaurants charge 7.35% on meals and 6.35% on other taxable sales. Connecticut bans card fees under any name, and a posted cash discount is the legal alternative.
New Haven restaurants work with two tax rates. Meals and certain beverages are taxed at 7.35%, which is Connecticut's general 6.35% plus an extra 1% that took effect October 1, 2019. Taxable goods that aren't meals take 6.35%. No Connecticut town adds its own sales tax, so those two rates are all a New Haven kitchen needs, and a cafe that also sells mugs should set both up in its POS.
What you can't add is a card fee. Sec. 42-133ff bars any charge that raises a customer's total because of how they pay, and the Department of Consumer Protection says a convenience fee tied to the payment method is banned too. Calling it a "service charge" changes nothing if only card payers see it. Since July 1, 2026, Sec. 42-536 has also required advertised prices to include any fee a customer must pay, so a mandatory charge that everyone pays belongs in the price on the menu.
The lawful way to reflect card costs is a cash discount, posted where customers will see it. List a cash price beside the card price on the menu, or put up signs stating the discount in dollars or as a percentage, and make sure the receipt shows money taken off. Our cash discount guide walks through the setup.
Counters also have to take cash under state law. The exemptions include phone and online orders and locations where nobody is employed to help customers in person, which matters if you're weighing a kiosk-only format.
The Census Bureau estimated New Haven's population at 138,774 on July 1, 2025, up 3.6% from its 2020 base. Statewide rules and sources are on our Connecticut page, and the restaurant payment guide covers tips, terminals and the rest of the setup. With card fees ruled out, the processing rate is the cost you can still cut. Interchange-plus pricing shows it line by line, and a free statement review tells you where you stand.

Common questions
What tax does a New Haven restaurant charge on meals?
7.35%: Connecticut's general 6.35% rate plus the additional 1% on meals and certain beverages, in effect since October 1, 2019. Taxable goods that aren't meals take 6.35%. New Haven has no local sales tax, because no Connecticut town levies one.
Can a New Haven restaurant add 3% for paying by card?
No. Sec. 42-133ff bars any fee that increases the total because of the payment method, and that covers credit, debit and every other way to pay. The Department of Consumer Protection treats a convenience fee tied to the payment method the same way. You can build card costs into menu prices and offer a posted discount for cash.
What if I call it a service charge instead of a card fee?
If only card payers pay it, the name doesn't matter: a charge triggered by the payment method is a surcharge under Connecticut law. A mandatory charge that every customer pays is a different question, but since July 1, 2026, Sec. 42-536 has required it to be included in the price you advertise or display. Either way, it can't be a surprise line on the bill.
Does a cash discount have to show on the receipt?
The Department of Consumer Protection says it should: the receipt shows a discount, not an added charge, so the bill starts from your regular price and a cash payer sees money taken off. The discount also has to be posted, either with cash and card prices listed together or with signs giving the discount in dollars or as a percentage.
Can a New Haven cafe stop taking cash?
Generally not. Connecticut requires retailers to accept cash, and it bars no-cash signs and higher prices for cash buyers. The exemptions cover phone, mail and online sales, parking lots and garages, membership warehouse clubs, and locations where nobody is employed to help customers in person. A New Haven cafe can also comply with a device that converts cash to a prepaid card, as long as the device meets the statute's conditions.
