What Is Sales Tax?

Sales tax is a consumption tax that is collected by the government on the sale of goods and services. In most cases, it is added to the price of a product at the time of purchase, and the vendor collects the tax from the customer before paying it to the government.

In many countries, this type of tax is called Value-Added Tax (VAT) or Goods and Services Tax (GST), which are slightly different from the traditional sales tax model used in the United States. Depending on the country, sales tax may or may not be included in the price you see on the shelf.


Sales Tax in the United States

There is no federal sales tax in the U.S. Instead, sales tax is imposed at the state and local levels. Each state has its own rules, rates, and exemptions. Some states do not impose a sales tax at all.

States with No Statewide Sales Tax

  • Alaska
  • Delaware
  • Montana
  • New Hampshire
  • Oregon

Even in states like Alaska, some local governments may still impose a sales tax.

How Sales Tax Works

Sales tax is usually applied only on retail purchases. Business-to-business transactions are often exempt. Rates vary widely:

  • Texas exempts prescription medicine and food seeds.
  • Vermont adds a 10% tax on alcoholic drinks consumed on-site.

How Important Is Sales Tax for State Revenue?

Sales tax is a key revenue source for many states. On average, it accounts for about 2% of Americans’ personal income and nearly one-third of state government revenue.

States That Rely Heavily on Sales Tax

  • Florida, Texas, Tennessee, and Washington generate more than 50% of their tax revenue from sales tax.
  • In contrast, New York only generates about 20% from sales tax.

History of Sales Tax in the U.S.

The roots of sales tax in the U.S. date back to colonial times when British-imposed sales taxes led to events like the Boston Tea Party and eventually the American Revolution.

The modern form of sales tax began during the Great Depression when states needed new revenue sources. Mississippi was the first to introduce a state sales tax in 1930, and other states quickly followed.


Can You Deduct Sales Tax on Federal Income Tax?

Yes, but only if you itemize deductions. Most taxpayers take the standard deduction, so fewer than 2% of Americans claim a sales tax deduction each year.

If you made large purchases (like a car, wedding, or big appliances), it might be better to deduct sales tax instead of state income tax. However, you can only deduct either state income tax or sales tax, not both.

To itemize:

  • Keep detailed purchase receipts
  • Use the IRS guidelines to track your deductions

What Is VAT (Value-Added Tax)?

VAT is a type of consumption tax used in more than 160 countries. Unlike U.S. sales tax, which is charged only to the final consumer, VAT is collected at each stage of production when value is added.

Key Points About VAT:

  • More difficult to evade due to multi-level collection
  • Helps control costs through the supply chain
  • More revenue-efficient than traditional sales tax
  • Can be regressive, affecting low-income earners more

What Is GST (Goods and Services Tax)?

GST is similar to VAT and is used in countries like:

  • India
  • Canada
  • Singapore
  • Malaysia

GST is also applied at multiple stages of the supply chain, making it different from the single-point collection method used for U.S. sales tax.
