How to use the sales tax calculator by state well
Key concepts, practical steps, and guidance for calculating and understanding sales tax.
A sales tax calculator by state computes the total sales tax on a purchase by combining the state tax rate with the local tax rate and applying it to the taxable portion of the purchase amount, accounting for exemptions and business purchase considerations.
Consumers estimating purchase costs, business owners calculating sales tax to collect, e-commerce sellers determining tax obligations by state, and accountants reconciling sales tax filings across multiple jurisdictions.
The combined rate (state plus local) is what matters for the actual tax amount. State rates are fixed, but local rates vary by jurisdiction. Always use the rate for the delivery address, not the seller's location, for destination-based states.
Workflow
Four practical steps
Use this calculator to determine the exact sales tax on any purchase and understand the rate components.
1
Enter your purchase amount.Use the pre-tax amount of the goods or services being purchased. If you have a tax-inclusive total, use the reverse calculation method.
2
Select your state and enter local rate.Choose the state where the purchase will be delivered (for destination-based states) or where the seller is located (for origin-based states). Look up your local rate from your state's tax authority.
3
Apply any exemptions.If part of the purchase is exempt (such as groceries in some states or qualifying medical equipment), enter the exempt amount to reduce the taxable base.
4
Review the full breakdown.Check the state tax, local tax, total tax, and effective combined rate. For business purchases, review whether resale or use tax exemptions may apply.
Review Checklist
What to validate first
Key details that affect sales tax calculations.
Most states are destination-based (tax at the buyer's location), but some (Texas, Ohio, others) are origin-based (tax at the seller's location). Know which rule your state follows.
Local rates change frequently as cities and counties adjust taxes. Verify your local rate on your state's department of revenue website for the most current data.
Not all products are taxed equally. Groceries, clothing, prescription drugs, and digital goods have varying tax treatment by state. Check your state's exemption list.
If you sell online across state lines, most states require sales tax collection once you exceed $100,000 in sales or 200 transactions. Track nexus thresholds carefully.
Business purchases for resale are typically exempt, but you must have a valid resale certificate on file. Expired or invalid certificates mean you owe the tax.
If you buy goods from out-of-state without paying sales tax, you likely owe use tax to your home state. This is the same rate as your state's sales tax.

FAQ
Sales tax questions, answered directly
Short answers for searchers and answer engines.
Five states have no state sales tax: Alaska, Delaware, Montana, New Hampshire, and Oregon. However, Alaska allows local jurisdictions to impose their own sales taxes.
State rates range from 0% to 7.25% (California). The average combined state and local rate is approximately 6.6%. Tennessee, Louisiana, and Arkansas have the highest combined rates when local taxes are included.
Yes, in most cases. Since the 2018 South Dakota v. Wayfair ruling, states can require online sellers to collect sales tax once they exceed economic nexus thresholds, commonly $100,000 in sales or 200 transactions.
Economic nexus is a tax obligation triggered by economic activity (sales volume or transaction count) in a state, rather than physical presence. Most states set the threshold at $100,000 in annual sales or 200 transactions.
Divide the tax-inclusive total by (1 + tax rate as decimal), then subtract. For example, with 7% tax: $107 / 1.07 = $100 pre-tax, so the tax is $7.
