What this means in New Hampshire
New Hampshire charges no sales tax at the state or local level. A $10,000 purchase that carries about $661 of tax at the all-state average combined rate of 6.61% carries $0 here. That arithmetic is why no-sales-tax states draw cross-border shoppers for cars, appliances and electronics — and why the saving is largest exactly on the purchases households plan in advance.
Groceries for home consumption are exempt, so the weekly food shop is largely outside this tax. A state that taxed a $150 weekly basket at New Hampshire's combined rate would collect about $0 a year from it; in New Hampshire that charge falls only on non-food items and prepared food. Sellers should still check category rules — the exemption covers food, not everything in a supermarket.
How to calculate New Hampshire sales tax (3 steps)
- Find your combined rate. Start with the 0% state rate, then add your county, city and any special-district rates for the exact purchase location.
- Multiply. Tax = taxable price × (combined rate ÷ 100). Shipping and discounts change the taxable base in some cases — discounts usually reduce it, delivery charges vary.
- Add (or extract). Total = price + tax. Working backwards from a tax-inclusive price: pre-tax price = total ÷ (1 + rate ÷ 100). Our calculator does both directions instantly.
