State & Local Sales Tax Rates, as of January 1, 2023

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. 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.

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. At one time, Delaware actually used its highway welcome sign to remind motorists that Delaware is the “Home of Tax-Free Shopping.”

Sales Tax Calculator FAQs

What is a sales tax calculator?

A sales tax calculator is a tool that calculates the amount of sales tax that will be added to a purchase based on the purchase price and the applicable tax rate. Sales tax calculators are commonly used by consumers to estimate the total cost of a purchase, including tax.

How do I use a sales tax calculator?

To use a sales tax calculator, simply enter the purchase price and the applicable tax rate into the calculator, and the calculator will automatically calculate the amount of sales tax that will be added to the purchase price. Some sales tax calculators may also provide a breakdown of the total cost, including tax.

What is the difference between a state sales tax and a local sales tax?

State sales taxes are taxes that are imposed by the state government on retail sales of goods and services within the state. Local sales taxes, on the other hand, are taxes that are imposed by local governments (such as cities, counties, or municipalities) on top of the state sales tax. The total sales tax rate for a purchase will depend on the combined state and local tax rates that apply.

How are sales tax rates determined?

Sales tax rates are determined by state and local governments. In the United States, each state has its own sales tax rate, which is typically a percentage of the purchase price. Local governments may also impose additional sales taxes on top of the state sales tax. The total sales tax rate for a purchase will depend on the combined state and local tax rates that apply.

Are sales taxes included in the advertised price of goods or services?

No, sales taxes are not typically included in the advertised price of goods or services. Instead, the sales tax is added to the purchase price at the time of sale. However, some businesses may choose to advertise prices that include the sales tax as a way of simplifying the purchasing process for consumers.

Are there any exemptions or special rules that apply to sales tax?

Yes, there may be exemptions or special rules that apply to sales tax, depending on the jurisdiction and the type of purchase. For example, some states may exempt certain types of goods or services from sales tax (such as groceries or prescription drugs), while others may impose additional taxes on specific items (such as luxury goods or cigarettes). Additionally, some states may offer sales tax holidays, during which certain purchases are exempt from sales tax for a limited period of time.

Is sales tax the same as value-added tax (VAT)?

No, sales tax and value-added tax (VAT) are two different types of taxes. Sales tax is a tax that is imposed on the sale of goods and services at the retail level, while VAT is a tax that is imposed on the value added at each stage of production and distribution of goods and services. VAT is commonly used in many countries outside of the United States.

Can sales tax be refunded or deducted?

In some cases, sales tax may be refunded or deducted. For example, if a business purchases goods for resale, it may be able to deduct the sales tax paid on those purchases from its own sales tax liability. Additionally, some states may offer sales tax refunds for purchases made by certain groups (such as non-residents or military personnel). However, the rules for sales tax refunds and deductions can vary widely by jurisdiction, so it's important to check with the relevant tax authorities for specific guidance.
