Source: Tax Foundation, State and Local Sales Tax Rates, Midyear 2026 (Jul 6, 2026). Rates as of July 1, 2026 (published July 6, 2026, by Abir Mandal). Values are percents. Average local rate is population-weighted. 'rank' is the combined-rate rank among the 50 states (ties share a rank); DC is not ranked (Tax Foundation shows a hypothetical rank of 38), so its rank is null. California (1.25%), Utah (1.25%) and Virginia (1%) levy mandatory statewide local add-ons, which are included in the state rate. Alaska, Delaware, Montana, New Hampshire and Oregon have no statewide sales tax; only Alaska allows local sales taxes (avg 1.82%, max local 7.85%). New Jersey's local rate is negative (-0.02%) because Salem County is exempt from the statewide rate and collects a lower local rate of 3.3125%. Special taxes in local resort areas are not counted. Hawaii, New Mexico and South Dakota have broad bases that include many business-to-business services. Combined rates may differ from state+local by 0.01 due to rounding.
