Common Questions About Sales Tax
Q: How is sales tax calculated?
A: Sales tax is calculated by multiplying the purchase price by the tax rate (as a decimal). For example, a $100 item with 8% tax costs $108 total ($100 + $8 tax).
Q: Why do sales tax rates vary by location?
A: Sales tax rates vary because they're set by different levels of government (state, county, city) and can be combined. Each jurisdiction sets its own rate based on local needs and budget requirements.
Q: Are there items that are exempt from sales tax?
A: Yes, many states exempt food, prescription drugs, and certain services from sales tax. Exemptions vary by state, so check your local tax laws for specific details.
Q: Do I pay sales tax on online purchases?
A: Yes, most online purchases are subject to sales tax. The 2018 Wayfair decision requires online retailers to collect tax if they meet certain sales thresholds in your state.
Q: How can I find my local sales tax rate?
A: You can find your local sales tax rate by checking your state's tax department website, using online tax calculators, or asking local businesses. Rates can change, so verify current rates.
Q: What's the difference between sales tax and use tax?
A: Sales tax is collected at the point of sale, while use tax is paid by the consumer on items purchased without paying sales tax (like out-of-state purchases). Use tax ensures fair taxation across all purchases.

Did you know that...?
The First Sales Tax Was Created in Ancient Egypt
The concept of sales tax dates back to ancient Egypt around 3000 BC, where a 10% tax was imposed on all commercial transactions. This early form of sales tax was collected to fund public works projects, including the construction of pyramids and other monumental structures. The tax was so effective that it became a model for taxation systems throughout the ancient world.
The modern sales tax system in the United States was first implemented in West Virginia in 1921 during the Great Depression as a way to generate revenue for state governments. Before this, most states relied primarily on property taxes. The sales tax was revolutionary because it was easier to collect and more difficult to avoid than property taxes.
💡 Fun Fact: The highest sales tax rate in the U.S. is 10.25% in Chicago, Illinois, while five states (Alaska, Delaware, Montana, New Hampshire, and Oregon) have no state sales tax at all!
