Enter a price and your zip code into the sales tax calculator above to find the correct amount of sales tax for any purchase. The tool applies current state and local sales tax rates so you can see the total cost in seconds.
Sales tax is a consumption tax added at the point of sale on goods and services. The rate you pay depends on where the transaction happens, not where the buyer lives. That means your zip code matters.
Across the United States, 45 states plus Washington, D.C. charge a statewide sales tax. Five states (Alaska, Delaware, Montana, New Hampshire, and Oregon) have no general sales tax, though some Alaska localities still collect local sales taxes.
Sales Tax Calculator
This free sales tax calculator works in two directions.
Price to total. Enter the sale price of an item, choose your state or type your zip code, and the calculator returns the sales tax amount plus the total you will pay.
Total to price (reverse calculation). Already have a receipt total? The calculator can separate the sales tax from the price of the item so you see how much tax you actually paid. This is sometimes called calculating sales tax backwards from the total.
The sales tax formula behind both modes is straightforward:
- Sales tax amount = Sale price × Total sales tax rate
- Total cost = Sale price + Sales tax amount
- Pre-tax price (reverse) = Total ÷ (1 + Total sales tax rate)
Results are estimates based on published rate tables. Always confirm with your local tax jurisdiction for the correct tax on high-value transactions like vehicles or business equipment.
How to Calculate Sales Tax
Calculating sales tax by hand takes three steps.
- Find your total sales tax rate. Add the base state sales tax rate to any county, city, or special district rates that apply to your location.
- Multiply the sale price by that combined rate. For example, a $200 item at a 8.25% combined rate: $200 × 0.0825 = $16.50 in sales tax.
- Add the tax to the price. $200 + $16.50 = $216.50 total.
If you need to reverse the calculation, divide the receipt total by 1 plus the tax rate. Using the same example: $216.50 ÷ 1.0825 = $200.
The sales tax calculator handles both directions automatically. Just enter your numbers and zip code.
Sales Tax Rate by State
Sales tax rates vary depending on the state, and many locations add county or city surcharges on top. Below is a breakdown of how those layers work.
State Sales Tax Rates
Each state sets its own base state sales tax rate. Here are some common reference points:
- California: 7.25% (the highest base rate in the U.S.)
- Georgia: 4%
- Texas: 6.25%
- New York: 4%
- Florida: 6%
- Louisiana: 4.45%
Five states collect no statewide sales tax at all: Alaska, Delaware, Montana, New Hampshire, and Oregon.
A base rate is only the starting point. Most shoppers pay more once local rates are added.
Local Sales Tax Rates
Counties, cities, and special districts often impose additional sales tax. These local tax rates can add anywhere from 0.5% to over 5% on top of the state rate.
For example, Georgia's state rate is 4%, but most Georgia counties add 3% to 4% in local sales taxes. That means shoppers in many parts of Georgia actually pay 7% to 8%.
Local rates change frequently. Your zip code is the fastest way to look up the current sales tax for your exact location.
Combined State and Local Sales Tax Rates
The combined sales tax rate is what you actually pay at the register. It equals the state rate plus all applicable local rates.
Some of the highest combined rates in the country reach above 10%. Parts of Louisiana, Tennessee, and Arkansas regularly exceed that mark. Meanwhile, a shopper in Portland, Oregon, pays 0% because neither the state nor the city charges sales tax.
The calculator on this page uses combined state and local sales tax rates matched to your zip code so the estimate reflects what you would really owe.
Sales Tax Rates by City
Sales tax rates by city can differ dramatically even within the same state. Two neighboring cities in the same county may charge different rates because of special taxing districts for transit, stadiums, or infrastructure.
A few examples:
| City | State Rate | Local Rate | Combined Rate |
|---|---|---|---|
| Los Angeles, CA | 7.25% | 2.25% | 9.50% |
| San Francisco, CA | 7.25% | 1.25% | 8.625% |
| Atlanta, GA | 4% | 4.9% | 8.9% |
| Chicago, IL | 6.25% | 4.75% | 10.25% |
| Houston, TX | 6.25% | 2% | 8.25% |
| Anchorage, AK | 0% | 0% | 0% |
These rates shift as local governments approve new measures. Enter a zip code in the calculator above to get the current sales tax rate for your specific city.
State and Local Sales Tax: How Rates Vary by Jurisdiction
The U.S. sales tax system is decentralized. There is no single national sales tax. Instead, each tax jurisdiction sets its own rules, rates, and exemptions.
Why rates vary so much:
- States choose different base rates (or no rate at all).
- Counties and cities layer on local taxes for schools, transit, public safety, or general revenue.
- Special purpose districts (hospital districts, water districts, transportation authorities) can add fractions of a percent.
- Rates change with voter-approved measures, legislative sessions, or sunset clauses.
This means a business selling across state lines needs to track rates for every jurisdiction where it has sales tax nexus. Nexus is the legal connection (physical presence, employees, or economic activity thresholds) that requires a business to collect sales tax in that state.
If your business has a physical location, warehouse, or enough sales volume in a state, you likely have nexus there and must collect the right amount of tax. Each state defines its own nexus laws, so check the rules for every state where you operate.
Sales Tax Exemptions
Not everything is subject to sales tax. Most states carve out exemptions for specific categories of goods, buyers, or transactions.
Common Exemption Categories
- Groceries. Many states exempt unprepared food from sales tax. Some (like Georgia) tax groceries at a reduced rate. Others (like California) fully exempt most grocery items but tax prepared food.
- Clothing. A few states, including Pennsylvania and New Jersey, exempt most clothing. New York exempts clothing items under $110.
- Prescription medications. Nearly every state exempts prescription drugs. Most also exempt over-the-counter medications or medical devices, though rules differ.
- Resale purchases. Businesses buying inventory for resale are generally exempt from sales tax at the wholesale level. They collect sales tax from the end customer instead. A resale certificate is typically required.
- Nonprofit and government purchases. Qualified nonprofits and government agencies are often exempt from sales tax with proper documentation.
- Digital goods. Rules vary widely. Some states tax digital downloads, streaming services, and software. Others do not.
Sales tax holidays are another form of temporary exemption. Several states offer annual weekends when certain purchases (school supplies, clothing, or emergency preparedness items) are exempt from sales tax.
If you are unsure whether a specific product or service is taxable in your state, check with your state revenue department. The calculator estimates tax on the assumption the item is taxable.
Sales Tax Deduction on Your Tax Return
When you file your federal tax return, the IRS lets you deduct either state and local income tax or state and local sales tax, but not both. This choice is made on Schedule A if you itemize deductions.
When to Use the Sales Tax Deduction
The general sales tax deduction works best for people who:
- Live in a state with no income tax (Texas, Florida, Nevada, Washington, Wyoming, South Dakota, or Alaska).
- Made large taxable purchases during the year, such as a vehicle, boat, or major home renovation materials.
- Paid more in sales tax than they would deduct for state income tax.
The IRS provides optional sales tax tables based on your income, family size, and state. You can add tax paid on major purchases on top of the table amount.
Keep receipts for big purchases. The sales tax calculator can help you estimate how much sales tax you paid on a specific item, which is useful when preparing your tax return.
The state and local tax (SALT) deduction is currently capped at $10,000 per return. That cap applies to the combined total of property tax plus either income tax or sales tax.
Collect Sales Tax and File Sales Tax Returns
If you sell taxable goods or services, most states require you to:
- Register for a sales tax permit. You generally need a permit in every state where you have nexus before you can legally collect sales tax. Collecting without a permit, or failing to collect when required, can result in penalties.
- Charge the correct sales tax rate. Use the rate for the delivery destination in most states (destination-based sourcing). A few states use origin-based sourcing, where the seller's location determines the rate.
- File sales tax returns on schedule. States assign filing frequencies (monthly, quarterly, or annually) based on your sales volume. Even if you collected zero tax in a period, you may still need to file a return.
- Remit the tax collected. The sales tax you charge customers is held in trust for the government. Late payments can trigger interest and penalties.
How often should you file sales tax returns? It depends on the state and your collection volume. High-volume sellers typically file monthly. Smaller sellers may file quarterly or annually. Your state will notify you of your assigned frequency when you register.
What happens if you forget to collect sales tax? You may still owe the tax out of pocket, plus interest and penalties. States can audit past transactions. If you accidentally overcharge sales tax, you generally must remit the overcharged amount to the state and may need to refund the customer.
Automated sales tax software can help businesses stay current with rate changes, calculate the correct tax at checkout, and file returns. The calculator on this page is a quick reference for individual transactions, not a substitute for a full compliance system.
Value-Added Tax vs. Sale Tax
Sales tax and value-added tax (VAT) both tax consumption, but they work differently.
| Feature | Sales Tax | Value-Added Tax (VAT) |
|---|---|---|
| Where collected | Only at the final retail sale | At every stage of production and distribution |
| Who remits | The retailer | Each business in the supply chain |
| Visibility | Usually shown as a separate line on receipts | Often included in the listed price |
| Common where | United States | Most of Europe, Canada (GST/HST), and 160+ countries |
In a VAT system, each business charges tax on its sales and claims a credit for VAT paid on its inputs. The net effect is similar to a sales tax: the end consumer bears the cost. But the collection mechanism spreads across the supply chain.
The U.S. does not use a federal VAT. If you are comparing prices internationally or running a business that deals with goods and services tax (GST) in other countries, a VAT calculator may be more appropriate for those transactions.
Use the Sales Tax Calculator for Sales Tax Questions
The sales tax calculator at the top of this page is a free, fast way to estimate the correct amount of sales tax on any purchase. Enter the price, select your state or type your zip code, and get an instant breakdown of state, local, and total tax.
Quick reminders:
- Results are estimates based on published rates. Confirm with your tax jurisdiction for high-value or unusual transactions.
- Rates change. The calculator uses current sales tax data, but newly enacted local measures may not be reflected immediately.
- Exemptions are not factored in automatically. If your item is exempt from sales tax in your state, the actual tax owed may be lower.
- This tool is for informational purposes. It is not tax advice and does not replace consultation with a tax professional for business compliance.
