Sales tax is a consumption tax imposed on the sale of goods and services. Unlike income tax, it's paid by consumers at the point of purchase and collected by businesses on behalf of states.
State vs. Local Tax: This calculator uses state-level rates only. Most states allow cities, counties, and special districts to add their own taxes on top of the state rate. For example, Chicago has a combined rate of 10.25% while the California state rate is 7.25% but can exceed 10% in some cities.
Tax Nexus: If your business has a "nexus" (physical presence, employees, or significant sales) in a state, you may be required to collect sales tax there. The 2018 Wayfair decision expanded nexus rules to include economic activity, meaning many online sellers now owe taxes in states where they have significant sales even without a physical presence.
Exemptions: Many states exempt necessities like groceries, prescription medicine, and clothing from sales tax. Some states also have exemption certificates for resellers who purchase goods for resale rather than personal use.
Use Tax: If you purchase goods from an out-of-state seller who doesn't collect tax, you may owe "use tax" to your state. This is essentially the same as sales tax but paid by the buyer directly to the state.
Frequently Asked Questions
Sales tax is calculated by multiplying the pre-tax price by the applicable tax rate. For example, a $100 purchase in California (7.25% state rate) would have $7.25 in sales tax, totaling $107.25. Note that actual rates may be higher due to local/city/county taxes.
Five states have no state-level sales tax: Delaware, Montana, New Hampshire, Oregon, and Alaska (though Alaska allows local taxes). These states rely on other forms of taxation like income or property taxes.
Gross sales tax is the total tax collected. Net sales tax is what you keep after subtracting the tax you paid on items purchased for resale (tax paid to suppliers). Businesses that resell goods can often claim a tax exemption or credit for taxes paid on inventory.
It depends on your state and your sales volume. Most states require collection once you exceed a certain threshold (often $100,000 in sales or 200 transactions). Some states also tax specific services. Always check your state's nexus requirements and consult a tax professional.
Tax-included pricing means the advertised price already contains the tax (common in some countries). Tax-excluded pricing (more common in the US) means tax is added at checkout. This calculator supports both directions: add tax to a base price, or reverse-calculate the pre-tax amount from a total.
