This tax rate is close to the US national average (7.4%).
Tax Amount = Pre-tax Amount × (Tax Rate ÷ 100)
Tax Amount = $100.00 × (7.5 ÷ 100) = $7.50
Final Price = Pre-tax Amount + Tax Amount
Final Price = $100.00 + $7.50 = $107.50

What is Sales Tax?
Sales tax is a consumption tax imposed by the government at the point of sale for goods and services. The tax is a percentage of the price of the product sold and collected by the retailer, who then passes it on to the government.
In the United States, sales tax is levied at the state, county, and local levels. There is no national sales tax. Most states have a base sales tax rate, and many localities add their own additional percentage.

Interpreting Your Calculation Results
Understanding the outputs: tax amount, pre-tax price, and final price.
The Sales Tax Calculator provides clear outputs based on your selected calculation type and inputs. Here's how to interpret them:
- Pre-Tax Price: This is the original price of the item or service before any sales tax is applied. If you chose to calculate the pre-tax amount from a total, this will be the primary result.
- Sales Tax Amount: This is the actual amount of tax calculated based on the pre-tax price and the specified tax rate. This value is crucial for understanding the tax portion of your purchase.
- Final Price (Total Price): This is the sum of the pre-tax price and the sales tax amount. It represents the total cost you will pay at the register or be billed.
Depending on the "Calculation Type" you select:
- If you input a Pre-Tax Price and Tax Rate, the calculator will primarily show you the Sales Tax Amount and the Final Price.
- If you input a Final Price (tax included) and Tax Rate, the calculator will primarily show you the Pre-Tax Price and the Sales Tax Amount that was part of the total.
Always ensure your input tax rate is correct for the relevant locality and item type, as this directly impacts the accuracy of all calculated values.

Applications & Examples
Practical uses and example calculations for sales tax.
Calculating Tax on a $100 item with 7% tax:
Finding Pre-Tax Price if Total was $53.50 with 7% tax:
1. Consumer Budgeting
When planning for a significant purchase (e.g., electronics, furniture, appliances), use the calculator to determine the final cost including sales tax. This helps avoid surprises at checkout and ensures you budget accurately.
Example: You want to buy a laptop listed at $1200 in a state with 6.5% sales tax. Calculate $1200 x 0.065 = $78 sales tax. Total cost = $1278.
2. Online Shopping
Before finalizing an online order, especially from a new retailer or one shipping to a different state, you can estimate the sales tax that will be applied based on the shipping address and local tax rate. Some carts show this late in the process.
3. Business Pricing and Invoicing
Businesses can use the calculator to correctly add sales tax to invoices for taxable goods or services. If a price needs to be quoted as tax-inclusive, they can use the "Pre-tax Amount" calculation to determine the base price.
Example: A consultant offers a service package for a total of $535, including a 7% sales tax. They can calculate the pre-tax service fee: $535 / 1.07 = $500. The invoice would show $500 service fee + $35 sales tax.
4. Comparing Prices Across Locations
If considering purchasing an item in different cities or states with varying sales tax rates, the calculator can help compare the final out-the-door price.
5. Verifying Receipts
Consumers can quickly verify if the sales tax charged on a receipt is accurate by inputting the pre-tax amount and the local sales tax rate.
Advanced Sales Tax Topics
1. Use Tax
Use tax is a tax on the storage, use, or consumption of a taxable item or service on which no sales tax has been paid. It typically applies when you buy items from out-of-state sellers who don't collect sales tax from you (e.g., some smaller online retailers). If your state has a sales tax, it likely has a corresponding use tax. You are generally responsible for self-reporting and paying use tax to your state, often through your annual income tax return.
Example: You buy a $500 item online from a seller who doesn't charge you sales tax. If your state's sales tax rate is 6%, you may owe $30 in use tax.
2. Nexus (Sufficient Physical Presence)
Historically, states could only require businesses to collect sales tax if they had a "physical presence" (nexus) in the state, like a store or warehouse. However, the 2018 Supreme Court case South Dakota v. Wayfair, Inc. changed this. States can now require out-of-state sellers to collect sales tax if their sales into the state exceed certain economic thresholds (e.g., $100,000 in revenue or 200 transactions annually). This is known as "economic nexus."
3. Tax on Shipping and Handling
Whether shipping and handling charges are taxable varies by state. Some states tax shipping if the item itself is taxable. Others only tax shipping if it's not separately stated on the invoice or if it includes handling charges. Some states don't tax shipping at all if it reflects actual postage costs.
4. Product and Service Taxability
The taxability of specific products and services can be complex. While most tangible goods are taxable, services are taxed differently across states. Digital goods (software, downloads, streaming) also have varying tax rules. Groceries and prescription drugs are often exempt or taxed at a lower rate in many states, but definitions of what qualifies can be precise.
5. Sales Tax Holidays
Many states offer temporary sales tax holidays (e.g., "tax-free weekends") for specific categories of items, like school supplies, clothing, or emergency preparedness items. These events have specific date ranges and price caps for eligible items.
