Sales taxes

What Are Sales Taxes?

Sales taxes are a type of consumption tax levied by a governing body on the sale of certain goods and services. Typically, these taxes are added to the purchase price at the point of sale and collected by the seller from the consumer, who then remits the funds to the appropriate tax authority. As a fundamental component of public finance, sales taxes represent a significant source of revenue for state and local governments, funding various public services such as education, infrastructure, and healthcare45. Unlike federal taxes, sales taxes are primarily administered at the state and local levels within the United States, with rates varying significantly by jurisdiction44.

History and Origin

The concept of taxing transactions dates back thousands of years, with ancient civilizations like Egypt taxing cooking oil and Imperial Rome under Julius Caesar implementing a 1% flat rate across his empire43. However, the modern, broad-based sales tax in the United States is a relatively recent development.

West Virginia was the first state to enact a statewide sales tax on May 3, 1921, which went into effect on July 1, 192142,41. Initially, this tax applied to a limited number of products, including coal, oil, natural gas, timber, and electric power40. The Great Depression, which began in 1929, spurred a more widespread adoption of sales taxes across the country as states sought to replenish their depleted treasuries due to declining property and income tax collections39,38. Mississippi introduced a more generalized, widespread sales tax in 1930, followed by many other states in the 1930s and 1940s37,36. By the end of the 1960s, most states had adopted a sales tax, with Vermont being the last in 196935. Today, 45 of the 50 states, along with the District of Columbia, impose a statewide sales tax34,33.

Key Takeaways

  • Sales taxes are consumption taxes levied on the sale of goods and services, primarily by state and local governments.
  • They are typically collected by the seller from the consumer at the point of purchase.
  • Sales taxes are a major source of revenue for states, used to fund public services.
  • The tax rates vary widely by state and locality, and certain goods or services may be exempt.
  • Sales taxes are often criticized for their regressive nature, disproportionately affecting lower-income households.

Formula and Calculation

The calculation of sales taxes is straightforward, applying a specified tax rate to the selling price of a taxable good or service.

The formula for calculating sales tax is:

Sales Tax Amount=Selling Price×Sales Tax Rate\text{Sales Tax Amount} = \text{Selling Price} \times \text{Sales Tax Rate}

The total amount paid by the consumer is:

Total Price=Selling Price+Sales Tax Amount\text{Total Price} = \text{Selling Price} + \text{Sales Tax Amount}

Where:

  • Selling Price: The price of the good or service before tax.
  • Sales Tax Rate: The percentage rate set by the taxing authority.
  • Sales Tax Amount: The dollar amount of tax applied to the sale.
  • Total Price: The final amount the consumer pays.

Interpreting Sales Taxes

Sales taxes are a direct cost added to the consumer's final purchase price. Interpreting sales taxes involves understanding how they impact consumer spending and government revenue. From a consumer's perspective, a higher sales tax rate means a greater total cost for the same item. From a government's perspective, sales tax collections reflect a portion of the economic activity within its jurisdiction.

The effective sales tax rate can differ based on the tax base, which refers to the scope of goods and services subject to the tax32,31. Many states exempt essential items like groceries, prescription medicines, and certain services to mitigate the burden on consumers, particularly those with lower incomes30,29. Understanding these exemptions is crucial for both businesses and consumers to accurately interpret the total cost of a transaction.

Hypothetical Example

Imagine a customer, Sarah, is purchasing a new bicycle from a local shop in a state with a 6% sales tax. The advertised price of the bicycle is $500.

  1. Calculate the Sales Tax Amount:
    Sales Tax Amount = Selling Price × Sales Tax Rate
    Sales Tax Amount = $500 × 0.06 = $30

  2. Calculate the Total Price:
    Total Price = Selling Price + Sales Tax Amount
    Total Price = $500 + $30 = $530

In this scenario, Sarah would pay a total of $530 for the bicycle, with $30 of that amount going towards the sales tax collected by the retailer and remitted to the state's department of revenue. This simple example illustrates how sales taxes directly increase the final price paid by the consumer.

Practical Applications

Sales taxes are integral to the financial operations of state and local governments. They are a primary source of funding for a broad range of public services and play a significant role in taxation policy.

  • Government Revenue: Sales taxes consistently rank as one of the largest sources of state tax revenue, often second only to individual income tax. 28This revenue supports critical public expenditures, from education and transportation to healthcare and public safety.
  • Funding Local Services: Beyond statewide levies, many cities and counties impose their own local sales taxes, providing vital funds for municipal services and projects,.27
  • E-commerce and Remote Sales: The advent of e-commerce significantly challenged traditional sales tax collection, which historically relied on a seller's physical presence (known as nexus) within a state. 26The U.S. Supreme Court's landmark 2018 decision in South Dakota v. Wayfair, Inc. overturned the physical presence rule, establishing that states can require out-of-state sellers with sufficient economic nexus (based on sales volume or transaction count) to collect and remit sales taxes,.25 This ruling significantly broadened states' ability to collect sales taxes on remote transactions and led to widespread adoption of economic nexus laws by states and the implementation of marketplace facilitator laws,.24 23More details can be found on the Tax Foundation's resource regarding South Dakota v. Wayfair.

Limitations and Criticisms

Despite their importance as a revenue source, sales taxes face several criticisms, particularly concerning their fairness and economic impact.

One of the most significant criticisms is their generally regressive tax nature,.22 A regressive tax takes a larger percentage of income from lower-income individuals than from higher-income individuals,.21 20This is because lower-income households typically spend a greater proportion of their total income on taxable goods and services, including basic necessities, leaving less for savings or investments, which are not subject to sales tax,,19.18 17Conversely, higher-income households tend to save or invest a larger share of their income, meaning a smaller percentage of their overall income is subject to sales taxes.
16
Economists and policymakers have debated this regressivity for decades, with some arguing that exemptions for necessities like food and medicine can mitigate the disproportionate burden,.15 14However, research from organizations such as the Brookings Institution highlights that a shift toward sales taxes can raise burdens on low- and middle-income households while potentially reducing taxes for higher earners. 13The shrinking sales tax base, due to the increasing share of the economy composed of untaxed services, has also led states to increase sales tax rates to maintain revenue, which can further exacerbate their regressive impact.

Sales Taxes vs. Use Tax

While closely related, sales taxes and use tax are distinct in their application and who is responsible for remittance.

Sales Tax: This is a tax imposed on the sale of goods and services by a retailer to an end consumer at the point of purchase. The retailer is legally obligated to collect the sales tax from the customer and then remit it to the state or local government. 11It is visible to the consumer as an added charge on their receipt.

Use Tax: This is a complementary tax to the sales tax, designed to be self-assessed and paid by the consumer when they purchase taxable goods or services outside their state of residence (or from a seller not legally required to collect sales tax) and then bring those items into their state for use, storage, or consumption,.10 9For example, if a resident of a state with sales tax buys an item online from a seller who does not collect sales tax, the buyer is typically responsible for remitting the equivalent use tax to their state. Historically, compliance with use tax has been low for individual consumers, but it is often enforced for large purchases like vehicles. 8The intent of the use tax is to prevent consumers from avoiding sales tax by purchasing items in jurisdictions with lower or no sales tax, and to ensure fairness for local businesses that are required to collect sales tax.

FAQs

Q1: Are sales taxes a federal tax?

No, sales taxes are not a federal tax in the United States. They are imposed and administered by state and local governments, meaning rates and rules vary significantly from one jurisdiction to another.

Q2: What goods or services are typically exempt from sales taxes?

While exemptions vary by state and locality, common items often exempted from sales taxes include unprepared food (groceries), prescription medications, and certain services. 6These exemptions are often implemented to reduce the regressive tax burden on low-income households for essential goods.

Q3: What is "sales tax nexus"?

Nexus refers to the legal connection between a business and a state that requires the business to collect and remit sales taxes. Historically, this connection required a physical presence, such as a store or warehouse. However, after the South Dakota v. Wayfair, Inc. Supreme Court decision, states can now establish economic nexus based on a business's volume of sales or number of transactions within the state, even without a physical presence,.5

Q4: How do sales taxes benefit states?

Sales taxes provide a stable and significant source of revenue for state and local governments. This revenue is crucial for funding a wide range of public services and programs, including education, transportation, public safety, and healthcare, contributing to the overall financial health of the state,.3

Q5: What is the difference between a sales tax and an excise tax?

A sales tax is a general tax applied to the retail sale of most goods and services. An excise tax, on the other hand, is a tax imposed on specific goods or services, such as tobacco, alcohol, gasoline, or luxury items. 1Excise taxes are often used to discourage consumption of certain goods or to fund specific programs related to the taxed product.
