Key Findings
- Forty-five states and the District of Columbia collect statewide sales taxes.
- Local sales taxes are collected in 38 states. In some cases, they can rival or even exceed state rates.
- The five states with the highest average combined state and local sales taxA sales tax is levied on retail sales of goods and services and, ideally, should apply to all final consumption with few exemptions. Many governments exempt goods like groceries; base broadening, such as including groceries, could keep rates lower. A sales tax should exempt business-to-business transactions which, when taxed, cause tax pyramiding. rates are Louisiana (9.55 percent), Tennessee (9.547 percent), Arkansas (9.48 percent), Washington (9.29 percent), and Alabama (9.22 percent).

Introduction
Retail sales taxes are one of the more transparent ways to collect tax revenue. While graduated income tax rates and brackets are complex and confusing to many taxpayers, sales taxes are easier to understand; consumers can see their tax burden printed directly on their receipts.
In addition to state-level sales taxes, consumers also face local sales taxes in 38 states. These rates can be substantial, so a state with a moderate statewide sales tax rate could actually have a very high combined state and local rate compared to other states. This report provides a population-weighted average of local sales taxes as of July 1, 2021, to give a sense of the average local rate for each state. Table 1 provides a full state-by-state listing of state and local sales tax rates.
2021 Combined State and Local Sales Tax Rates
Five states do not have statewide sales taxes: Alaska, Delaware, Montana, New Hampshire, and Oregon. Of these, Alaska allows localities to charge local sales taxes.[1]
The five states with the highest average combined state and local sales tax rates are Louisiana (9.55 percent), Tennessee (9.547 percent), Arkansas (9.48 percent), Washington (9.29 percent), and Alabama (9.22 percent). The five states with the lowest average combined rates are Alaska (1.76 percent), Hawaii (4.44 percent), Wyoming (5.39 percent), Wisconsin (5.43 percent), and Maine (5.50 percent).
2021 State Sales Tax Rates
California has the highest state-level sales tax rate, at 7.25 percent.[2] Four states tie for the second-highest statewide rate, at 7 percent: Indiana, Mississippi, Rhode Island, and Tennessee. The lowest non-zero state-level sales tax is in Colorado, which has a rate of 2.9 percent. Five states follow with 4 percent rates: Alabama, Georgia, Hawaii, New York, and Wyoming.[3]
No state rates have changed since April 2019, when Utah’s state-collected rate increased from 5.95 percent to 6.1 percent. (The state rate is now officially 4.85 percent, but the state collects an additional 1.25 percent in mandatory taxes that are distributed to local governments, in addition to local option taxes imposed by localities.)[4]
2021 Local Sales Tax Rates
The five states with the highest average local sales tax rates are Alabama (5.22 percent), Louisiana (5.10 percent), Colorado (4.82 percent), New York (4.52 percent), and Oklahoma (4.45 percent).
No states saw ranking changes of more than one place since January. Most states which saw improved rankings (Kansas, Minnesota, and Tennessee) did so only in comparison to those that enacted more substantial local rate increases.
Tampa and the rest of Hillsborough County, Florida, saw a non-legislative tax decrease in February, as the Florida Supreme Court ruled the county’s 1 percent transportation surtaxA surtax is an additional tax levied on top of an already existing business or individual tax and can have a flat or progressive rate structure. Surtaxes are typically enacted to fund a specific program or initiative, whereas revenue from broader-based taxes, like the individual income tax, typically cover a multitude of programs and services. unconstitutional.[5] The rate subsequently decreased from 8.5 percent to 7.5 percent, helping to drop the state’s standing from 22nd to 23rd highest.
California moved in the opposite direction, going from 9th to 8th highest. This shift is largely due to sales tax increases in the Bay Area. San Francisco and San Jose both increased their sales taxes by 0.125 percentage points (to 8.625 and 9.375 percent, respectively) as a result of voter-approved measures, while many other jurisdictions in the area—including the counties of Alameda, San Mateo, and Santa Clara—likewise saw increases.[6] Sales taxes rose elsewhere in the state, including in West Hollywood, where voters approved an increase from 9.5 to 10.25 percent, which went into effect in February.[7]
Louisiana reclaimed its dubious first place spot since January. Rate increases in Evangeline, St. Mary, Tangipahoa, West Feliciana, and other assorted small parishes contributed to the shift.[8] In South Carolina, Laurens and Edgefield counties each saw increases of 1 percentage point,[9] nudging the state from 18th to 17th highest.
It must be noted that some cities in New Jersey are in “Urban Enterprise Zones,” where qualifying sellers may collect and remit at half the 6.625 percent statewide sales tax rate (3.3125 percent), a policy designed to help local retailers compete with neighboring Delaware, which forgoes a sales tax. We represent this anomaly as a negative 0.03 percent statewide average local rate (adjusting for population as described in the methodology section below), and the combined rate reflects this subtraction. Despite the slightly favorable impact on the overall rate, this lower rate represents an implicit acknowledgment by New Jersey officials that their 6.625 percent statewide rate is uncompetitive with neighboring Delaware, which has no sales tax.

Notes: (a) City, county and municipal rates vary. These rates are weighted by population to compute an average local tax rate. (b) Three states levy mandatory, statewide, local add-on sales taxes at the state level: California (1%), Utah (1.25%), and Virginia (1%). We include these in their state sales tax. (c) The sales taxes in Hawaii, New Mexico, and South Dakota have broad bases that include many business-to-business services. (d) Special taxes in local resort areas are not counted here. (e) Salem County, N.J., is not subject to the statewide sales tax rate and collects a local rate of 3.3125%. New Jersey’s local score is represented as a negative.

The Role of Competition in Setting Sales Tax Rates
Avoidance of sales tax is most likely to occur in areas where there is a significant difference between jurisdictions’ rates. Research indicates that consumers can and do leave high-tax areas to make major purchases in low-tax areas, such as from cities to suburbs.[10] For example, evidence suggests that Chicago-area consumers make major purchases in surrounding suburbs or online to avoid Chicago’s 10.25 percent sales tax rate.[11]
At the statewide level, businesses sometimes locate just outside the borders of high sales-tax areas to avoid being subjected to their rates. A stark example of this occurs in New England, where even though I-91 runs up the Vermont side of the Connecticut River, many more retail establishments choose to locate on the New Hampshire side to avoid sales taxes. One study shows that per capita sales in border counties in sales tax-free New Hampshire have tripled since the late 1950s, while per capita sales in border counties in Vermont have remained stagnant.[12] At one time, Delaware actually used its highway welcome sign to remind motorists that Delaware is the “Home of Tax-Free Shopping.”[13]
State and local governments should be cautious about raising rates too high relative to their neighbors because doing so will yield less revenue than expected or, in extreme cases, revenue losses despite the higher tax rate.
Sales Tax Bases: The Other Half of the Equation
This report ranks states based on tax rates and does not account for differences in tax bases (e.g., the structure of sales taxes, defining what is taxable and nontaxable). States can vary greatly in this regard. For instance, most states exempt groceries from the sales tax, others tax groceries at a limited rate, and still others tax groceries at the same rate as all other products.[14] Some states exempt clothing or tax it at a reduced rate.[15]
Tax experts generally recommend that sales taxes apply to all final retail sales of goods and services but not intermediate business-to-business transactions in the production chain. These recommendations would result in a tax system that is not only broad-based but also “right-sized,” applying once and only once to each product the market produces.[16] Despite agreement in theory, the application of most state sales taxes is far from this ideal.[17]
Hawaii has the broadest sales tax in the United States, but it taxes many products multiple times and, by one estimate, ultimately taxes 105 percent of the state’s personal income.[18] This base is far wider than the national median, where the sales tax applies to 34.25 percent of personal income.[19]
Methodology
Sales Tax Clearinghouse publishes quarterly sales tax data at the state, county, and city levels by ZIP code. We weight these numbers according to Census 2010 population figures to give a sense of the prevalence of sales tax rates in a particular state.
It is worth noting that population numbers are only published at the ZIP code level every 10 years by the U.S. Census Bureau, and that editions of this calculation published before July 1, 2011, do not utilize ZIP code data and are thus not strictly comparable.
It should also be noted that while the Census Bureau reports population data using a five-digit identifier that looks much like a ZIP code, this is actually what is called a ZIP Code Tabulation Area (ZCTA), which attempts to create a geographical area associated with a given ZIP code. This is done because a surprisingly large number of ZIP codes do not actually have any residents. For example, the National Press Building in Washington, D.C., has its own ZIP code solely for postal reasons.
For our purposes, ZIP codes that do not have a corresponding ZCTA population figure are omitted from calculations. These omissions result in some amount of inexactitude but overall do not have a palpable effect on resultant averages because proximate ZIP code areas which do have ZCTA population numbers capture the tax rate of those jurisdictions.
Conclusion
Sales taxes are just one part of an overall tax structure and should be considered in context. For example, Tennessee has high sales taxes but no wage income tax, whereas Oregon has no sales tax but high income taxes. While many factors influence business location and investment decisions, sales taxes are something within policymakers’ control that can have immediate impacts.
