What New Hampshire merchants need to know
New Hampshire is among the majority of states with no law limiting a merchant's ability to add a credit card surcharge. The rules that apply come entirely from the card networks, not the state capitol: the surcharge can't exceed your actual cost of acceptance (never more than 3% if you accept Visa), it applies to credit cards only — never debit or prepaid, even when a debit card is run as 'credit' — and it must be disclosed at the entrance, at the register, and on the receipt.
New Hampshire has no state statute restricting surcharges and, notably, no state sales tax — one of the reasons NH retail draws significant cross-border shopping traffic from Massachusetts and Maine, both of which prohibit surcharging outright. NH merchants near those borders are on the permissive side of a sharp compliance line.
The cash discount alternative
Wherever surcharge rules get complicated, dual pricing doesn't: posting a card price and offering a discount for cash is legal in all 50 states when it's structured correctly — the posted price must be the card price, with cash receiving a true discount. The economics match a surcharge; the compliance profile usually beats it.
Because New Hampshire has no surcharge-specific restriction, the choice between surcharging and a cash discount program comes down to what fits your business and customers, not legal risk — both are compliant here.
