Key Findings

  • Sales taxes account for 29.52 percent of state taxA tax is a mandatory payment or charge collected by local, state, and national governments from individuals or businesses to cover the costs of general government services, goods, and activities. revenue, but most sales taxes are imposed on narrow—and still-narrowing—bases, with average 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. breadth of only 29.71 percent and a median of 35.72 percent.
  • Sales tax bases range from 19.32 percent of personal income in Massachusetts to 93.89 percent in Hawaii; the Massachusetts base is extremely narrow, while the Hawaii base features significant tax pyramidingTax pyramiding occurs when the same final good or service is taxed multiple times along the production process. This yields vastly different effective tax rates depending on the length of the supply chain and disproportionately harms low-margin firms. Gross receipts taxes are a prime example of tax pyramiding in action. .
  • Within states with a sales tax, the mean taxpayer cost of sales taxes is $1,131, or about $199 per percentage point on the tax rate.
  • An ideal sales tax is imposed on all final consumption, both goods and services, but excludes intermediate transactions to avoid tax pyramiding.
  • Sales tax breadth has declined from a mean of 49.98 percent in 2000 to the current 29.52 percent, reflecting continued erosion that has largely been offset by an increase in the mean state rate from 5.16 to 6.00 percent over the period.
  • The pandemic has yielded temporary fluctuations as the amount and composition of consumer expenditures has changed, though long-term sales tax trends remain highly visible in the data.


Sales taxes account for 29.5 percent of all state tax revenue, second only to individual income taxes (40 percent) in their contribution to state receipts. Reliance on sales taxes, however, varies dramatically, from 13.4 percent in the District of Columbia to 65.4 percent in South Dakota. State reliance on sales tax depends on its mix of other taxes (South Dakota, for instance, forgoes income taxes, while the District of Columbia has high-rate income taxes); its sales tax rate; and, importantly, the breadth of its sales tax baseThe tax base is the total amount of income, property, assets, consumption, transactions, or other economic activity subject to taxation by a tax authority. A narrow tax base is non-neutral and inefficient. A broad tax base reduces tax administration costs and allows more revenue to be raised at lower rates. .

The narrowest base, in California, is only 19 percent of personal income, whereas the broadest base, in Hawaii, is almost five times that at 94 percent of personal income. (Hawaii’s sales tax base has historically exceeded 100 percent of personal income but took a hit as the island’s economic profile changed during the pandemic.) The ideal sales tax base consists of all final consumption, both goods and services, while exempting intermediate goods to avoid tax pyramiding, where the tax is imposed multiple times on the same final product. The California base is woefully narrow, riddled with exemptions and excluding vast swaths of personal consumption. Hawaii’s base, by contrast, while including certain economically inefficient inclusions, has elements of gross receipts taxA gross receipts tax, also known as a turnover tax, is applied to a company’s gross sales, without deductions for a firm’s business expenses, like costs of goods sold and compensation. Unlike a sales tax, a gross receipts tax is assessed on businesses and apply to business-to-business transactions in addition to final consumer purchases, leading to tax pyramiding. ation and frequently double-taxes transactions. (It also benefits substantially from spending by tourists.) Both states miss the mark—in opposite directions.

Consumption taxes are among the more economically efficient forms of taxation and are a major component of tax systems across the world. However, consumption taxes play a much smaller role in the United States than they do in most other highly developed countries, which often impose value-added taxes (VATs) at the national level. In fact, the U.S. is the only nation in the Organisation for Economic Co-operation and Development (OECD) which does not levy a VAT, and overall American reliance (at all levels of government) on consumption taxes is scarcely more than one-third the OECD average.[1] While the federal government does impose excise taxes on certain goods and services, like motor fuel, tobacco, alcohol, airfare, and certain health expenditures, most consumption taxA consumption tax is typically levied on the purchase of goods or services and is paid directly or indirectly by the consumer in the form of retail sales taxes, excise taxes, tariffs, value-added taxes (VAT), or an income tax where all savings is tax-deductible. revenue in the United States is generated at the state and local levels—primarily through retail sales taxes.

Despite the importance of sales taxes to state coffers, and notwithstanding the economic arguments for reliance on a broad-based, low-rate sales tax regime (for which the case is made below), state sales tax bases are narrowing, forcing states to either raise rates or shift to other sources of tax revenue in response to this continuous erosion. These trends will continue until states undertake meaningful sales tax modernization.[2]

Standardized Collections and Burdens

In fiscal year 2021, state retail sales taxes yielded $375.3 billion in revenue and accounted for 29.52 percent of state tax collections at a tax cost of $1,131 per person. Five states—Alaska, Delaware, Montana, New Hampshire, and Oregon—forgo a state-level sales tax. Among the 45 states and the District of Columbia which levy state-level sales taxes, reliance is 30.26 percent, and the per capita burden is $1,160, with a weighted average state sales tax rate of 6.00 percent (excluding local sales taxes).

All tax data for FY 2021 are somewhat anomalous due to the pandemic. Sales tax collections rose as disposable income increased and consumer expenditures were channeled into more purchases that tend to be included in sales tax bases. This helped reduce the measured erosion of sales tax bases without indicating any underlying change in policy. Certain states saw significant swings as the composition of consumption changed, Hawaii being a notable—and likely temporary—example. Sales tax reliance, however, contracted at the same time that sales tax receipts increased, since a combination of federal pandemic responses and a booming stock market caused income tax receipts to soar higher still.

For purposes of these calculations, states’ reported sales tax collections are adjusted to reflect the different ways states report their sales tax revenues to the U.S. Census Bureau. In most states, for instance, the sale of an automobile—a big-ticket item that generates substantial sales tax revenue—is subject to state sales tax (sometimes with a dollar cap) and the resulting revenue is reported as sales tax revenue. In 10 states, however, the tax on automobiles is imposed at the same rate as the general sales tax, and revenues are deposited into the general fund, but the state reports this revenue as selective rather than general sales tax revenue. Since the tax treatment is functionally identical regardless of the name or reporting standards applied, we adjust to “normalize” the treatment. Similarly, some state-collected shares of local sales taxes are included in Census data, along with revenues that are properly attributable to separate excise or gross receipts taxes. We account for these and other disparities in revenue reporting.[3]

Accordingly, the adjusted retail sales tax figures used here differ from those reported by the U.S. Census Bureau, which are frequently cited, including by the Tax Foundation, in other contexts. In these adjustments, and in our broader methodology and approach, we continue the work of the late Professor John Mikesell, the former Chancellor’s Professor of Public and Environmental Affairs Emeritus at Indiana University, who developed this methodology and maintained these datasets for many years.[4]

Table 1 presents data on total state tax revenues, adjusted sales tax revenues, per capita sales tax burdens overall and per percentage point of the state sales tax rate, and sales tax revenues as a percentage of personal income. Notably, states which generate low sales tax revenue per percentage of the rate, indicative of a narrower sales tax base (see Table 2), tend not to make up the difference through higher rates, though rates are inversely correlated with both per capita collections per percentage of rate and sales tax breadth, with coefficients of -0.21 and -0.23 respectively. These correlations are smaller than in prior years, possibly a temporary artifact of changed spending patterns during the pandemic.

Sales Tax Breadth and Reliance

Public finance scholars and tax policy researchers have their fair share of disagreements on taxation, but the sales tax is an area of surprising consensus. Decades ago, scholar John Due wrote that “sales tax structure should produce a uniform distribution in consumption, should be neutral regarding methods of production and distribution, and should be collected at a reasonable cost.”[5] Another leading tax scholar, Charles McLure, identified the ideal sales tax as a destination-based tax on all final consumption (but only final consumption).[6] These standards are broadly accepted, as are several related precepts and observations:

  1. An ideal sales tax is imposed on all final consumption, both goods and services;
  2. An ideal sales tax exempts all intermediate transactions (business inputs) to avoid tax pyramiding;
  3. Sales taxes should be destination-based, meaning that tax is owed in the state and jurisdiction where the good or service is consumed;
  4. The sales tax is more economically efficient than many competing forms of taxation, including the income tax, because it only falls on present consumption, not saving or investment;
  5. Because lower-income individuals have lower savings rates and consume a greater share of their income, the sales tax can be regressive, though broadening the base to include additional consumer services (much more heavily consumed by higher-income individuals) represents a progressive change;
  6. The sales tax scales well with ability to pay, because it grows with consumption and is therefore more discretionary than many other forms of taxation; and
  7. Consumption is a more stable tax base than income, though the failure to tax most consumer services is leading to a gradual erosion of sales tax revenues as services become an ever-larger share of consumption.

Taxes should apply to all final consumption in service of economic neutrality, the idea that taxes should not interfere with economic decision-making any more than is strictly necessary, nor should they pick winners and losers. It is not the role of the tax code to favor piano lessons over baseball bats or e-books over hardcovers. It makes little sense to tax the purchase of a lawn mower but not tax the purchase of lawn care services that obviate the need to own a mower.

The sales tax should also be broad-based in service of tax equity.[7] Sales taxes have two potential sources of regressivity: one, the propensity of lower-income individuals to consume a greater share of their income, and two, a scope of taxable consumption that is more likely to fall on the sorts of transactions which dominate the consumption of lower- and middle-income individuals.

Policymakers often exempt or lower rates on certain classes of consumption as a progressive reform. Utah’s reduced rate on groceries is one such example—though there is reason to believe it may not be terribly effective. Prepared foods are taxed at the standard rate and most of the progressivity of taxing unprepared foods is addressed by the exemption for SNAP (food stamps) and WIC purchases, while the exemption is enjoyed by high-income earners as well—who often spend considerably more on groceries.

In fact, lower-income taxpayers would actually be better off if groceries were fully included in sales tax bases (while retaining the federally-indicated exemption of SNAP and WIC purchases) and revenue-neutral adjustments made to the tax rate.[8] The lower grocery rate is designed to create progressivity but largely fails to do so. Yet, at the same time, policymakers have largely neglected a much more straightforward way to promote equity within the sales tax.

Consumption of personal services tends to be more discretionary than consumption of goods. Consequently, higher-income individuals tend to spend a greater share of income on services, which are frequently untaxed. Expanding the sales tax base to additional services rights an accidental wrong in the sales tax as currently formulated, one that presently favors wealthier individuals.

While ideal sales tax bases are broad, however, they should not be so broad as to cover intermediate transactions, often called business inputs. To varying degrees, these business-to-business transactions are taxed in every state with a sales tax, meaning that the sales tax is often embedded in the final price of a good or service several times over. This is not an ineluctable law of consumption taxes, but it has, unfortunately, been the reality in the United States.

In Europe, VATs are structurally designed to avoid such double taxationDouble taxation is when taxes are paid twice on the same dollar of income, regardless of whether that’s corporate or individual income. ; while each stage of production is taxed, the tax only falls on the incremental increase in value, such that, when the product is finally sold to a consumer, the VAT is imposed on 100 percent of its value—no more, no less. Theoretically, a retail sales tax could also exempt business inputs altogether, either by adopting a sufficiently robust set of exemptions or by tying the exemption to the identity of the purchaser rather than the nature of the product. In practice, though, no state has succeeded in eliminating all business inputs from the sales tax base, even though state revenue offices frequently cite it as an important principle of sales taxation.

A well-structured sales tax is imposed on all final consumer goods and services while exempting all purchases made by businesses that will be used as inputs in the production process. This is not because businesses deserve special treatment under the tax code, but because applying the sales tax to business inputs results in multiple layers of taxation embedded in the price of goods once they reach final consumers, a process known as “tax pyramiding.” The result is higher and inequitable effective tax rates for different industries and products, which is both nonneutral and nontransparent, hiding actual tax costs from consumers.

Fundamentally, the sales tax is designed as a tax on household consumption, and it works poorly when applied to any other base. As Professor Mikesell, who created and long maintained this series on sales tax breadth, once explained:

What tax policy is a retail sales tax expected to be carrying out? Its essential logic is to distribute the cost of government according to household consumption expenditure. It is not an effective handle on any other fundamental base. It is not an income tax because it makes no allowance for costs associated with generating receipts from sales. It is not a punitive excise on use of resources in ways that are luxurious or harmful to ourselves or others. It is not a business activity tax with intent to distribute the cost of government according to business utilization of public services. It is the U.S. approach, albeit an imperfect one, to impose a general levy on consumption expenditure, collected on an indirect or transaction basis like the value-added tax, but applied only at the last transaction in the chain of production and distribution leading to the household consumer. If the intent is to distribute governmental cost on a basis other than household consumption, some tax format other than the retail sales tax should be applied.[9]

Table 2 provides data on sales tax breadth and reliance, along with each state’s statutory state-level rate as of 2020. Reliance is defined as retail sales tax collections as a percentage of total state tax revenue, and breadth represents the share of the state’s economy, as measured by state personal income, included in the sales tax base.

The median sales tax rate in 2021 was 6.00 percent, and mean reliance on state sales taxes in the 45 states (plus the District of Columbia) which impose them was 30.26 percent (median of 31.00 percent). The District of Columbia (13.38 percent), Vermont (14.40 percent), and New York (14.98 percent) all generate less than 15 percent of state tax revenue from sales taxes, while another three states derive more than 60 percent of revenue from it: South Dakota (65.39 percent), Texas (62.35 percent), and Florida (60.58 percent).

Similarly, sales tax breadth is below 30 percent in 15 states, led by California (19.32 percent), Massachusetts (21.62 percent), New York (23.10 percent), and Virginia (23.61 percent), and is above 50 percent in four states: Washington (52.70 percent), South Dakota (53.90 percent), New Mexico (58.24 percent), and Hawaii (93.89 percent). The states which have historically seen the greatest sales tax breadth took a hit during the pandemic. Last year, for instance, Hawaii exceeded 119 percent, while New Mexico and South Dakota were both above 60 percent. For FY 2021, mean sales tax breadth is 29.52 percent, while the median is slightly higher at 31.00 percent. In the vast majority of states, sales taxes continue to be imposed on artificially narrow bases.

Sales tax breadth has narrowed in recent years, as personal services (largely exempted) have grown as a share of final consumption and lawmakers have continued to carve out existing tax bases. Professor Mikesell calculated a mean sales tax breadth of 49.98 percent in 2000,[10] which has plummeted to 29.52 percent in 2020. Unsurprisingly, rates have risen: the mean state rate was 5.16 percent in 2000 compared to 6.00 percent today (medians of 5.0 and 6.0 percent, respectively) even as reliance has declined, from a mean of 35.29 percent to today’s 29.52 percent (medians of 33.54 and 31.00 percent, respectively).

Sales taxes raise about the same amount as a percentage of state tax revenue as they did two decades ago, but this relative stability belies an important shift, with higher rates compensating for continuous base erosion. By failing to keep pace with modern consumption patterns, sales taxes have become less neutral, less equitable, and less economically efficient over time. States vary dramatically in sales tax breadth, but nearly all are below what most economists and public finance scholars would recommend, even as each state includes some share of intermediate transactions, which should appropriately be exempted to avoid tax pyramiding. The sales tax is too important a part of states’ revenue toolkits to be permitted further erosion, making sales tax modernization a vital project of the 2020s.
