What is Sales and Use Tax?
Sales tax is a consumption tax imposed by a government on the sale of goods and services. It is typically collected by the retailer at the point of sale. Use tax, on the other hand, is a tax on the use, storage, or consumption of tangible personal property or services that was not subject to sales tax at the time of purchase. It’s often incurred when you buy something from an out-of-state or online seller who doesn’t collect sales tax for your state. Our Sales and Use Tax Calculator helps you determine these amounts.
Individuals and businesses who purchase taxable goods or services from sellers who do not collect sales tax for their jurisdiction are generally required to report and pay use tax directly to their state’s taxing authority. The Sales and Use Tax Calculator is useful for anyone wanting to estimate the tax before a purchase or calculate the use tax they owe.
A common misconception is that if you buy something online and aren’t charged sales tax, you don’t owe any tax. However, you likely owe use tax, which is usually the same rate as the sales tax in your area. This Sales and Use Tax Calculator can help clarify the amount.
Sales and Use Tax Formula and Mathematical Explanation
The calculation of sales or use tax is generally straightforward:
- Determine the Taxable Amount: This is the portion of the purchase price that is subject to tax. It includes the base price and often shipping and handling charges, depending on state laws. Taxable Amount = Base Price + Taxable Shipping & Handling.
- Convert the Tax Rate: The tax rate is usually given as a percentage, so convert it to a decimal by dividing by 100 (e.g., 7% becomes 0.07).
- Calculate the Tax: Multiply the Taxable Amount by the decimal tax rate. Tax = Taxable Amount * (Tax Rate / 100).
- Calculate the Total Amount: Add the Tax to the original purchase price plus non-taxable shipping (if shipping wasn’t included in taxable amount) or just Taxable Amount + Tax if shipping was included. Total Amount = Purchase Price + Shipping + Tax.
Our Sales and Use Tax Calculator automates these steps.
| Variable | Meaning | Unit | Typical Range |
|---|---|---|---|
| Purchase Amount | The base price of the goods or services before tax and shipping. | Currency ($) | 0 – 1,000,000+ |
| Shipping Amount | The cost of shipping and handling. | Currency ($) | 0 – 1,000+ |
| Taxable Shipping | Indicates if shipping is taxed (depends on jurisdiction). | Boolean | Yes/No |
| Tax Rate | The combined state and local sales/use tax rate. | Percentage (%) | 0 – 15 |
| Taxable Amount | The amount on which tax is calculated (Purchase + Taxable Shipping). | Currency ($) | 0 – 1,000,000+ |
| Total Tax | The calculated sales or use tax. | Currency ($) | 0 – 150,000+ |
| Total Amount | The final cost including the base price, shipping, and tax. | Currency ($) | 0 – 1,150,000+ |

Practical Examples (Real-World Use Cases)
Example 1: Online Purchase with Taxed Shipping
Sarah buys a laptop online for $1200. The shipping cost is $30, and her state (with a combined 6.5% tax rate) taxes shipping charges.
Using the Sales and Use Tax Calculator:
- Purchase Amount: $1200
- Shipping Amount: $30 (taxable)
- Tax Rate: 6.5%
- Taxable Amount: $1200 + $30 = $1230
- Total Tax: $1230 * 0.065 = $79.95
- Total Amount Due: $1200 + $30 + $79.95 = $1309.95
Example 2: Out-of-State Purchase (Use Tax Owed)
John buys furniture from an out-of-state seller for $2000, and the seller doesn’t collect sales tax for John’s state. Shipping is $150, and John’s state (with a 5% use tax rate) does not tax separately stated shipping charges if the seller doesn’t collect.
Using the Sales and Use Tax Calculator:
- Purchase Amount: $2000
- Shipping Amount: $150 (not taxable in this scenario)
- Tax Rate: 5%
- Taxable Amount: $2000
- Total Tax (Use Tax): $2000 * 0.05 = $100
- Total Amount Paid to Seller: $2000 + $150 = $2150
- Use Tax Owed to State: $100
John would need to remit the $100 use tax to his state. For more on use tax explained, see our guide.

Key Factors That Affect Sales and Use Tax Results
- Tax Rate: The most direct factor. Higher rates mean more tax. Rates vary significantly between states and even localities.
- Taxability of Goods/Services: Not all goods and services are taxed uniformly. Some items like groceries or prescription drugs might be exempt or taxed at a lower rate. Check our taxable goods and services list.
- Taxability of Shipping & Handling: Whether shipping is taxed can change the taxable base and thus the total tax. This varies by state.
- Purchase Price: The higher the base price, the higher the tax amount, assuming a fixed rate.
- Location of Sale/Use: The tax rate is determined by the location where the sale is made or where the item is used/delivered (especially for online sales and use tax). Remote seller nexus rules impact this.
- Seller’s Obligation to Collect: If the seller has nexus in your state, they are usually required to collect sales tax. If not, you are responsible for remitting use tax.
- Exemptions: Certain buyers (e.g., government, non-profits) or types of purchases might be exempt from sales tax.
Understanding these factors helps in accurately using the Sales and Use Tax Calculator and managing tax obligations.
Frequently Asked Questions (FAQ)
- What’s the difference between sales tax and use tax?
- Sales tax is charged by the seller at the point of sale. Use tax is paid by the buyer directly to the state when sales tax was not collected on a taxable purchase, often from out-of-state or online sellers. The rates are usually the same.
- Do I have to pay use tax on all online purchases?
- If you purchase taxable items online from a seller who does not collect sales tax for your state, and the items are for use, storage, or consumption in your state, you generally owe use tax. See our online purchase tax guide.
- How do I know if shipping is taxable?
- The taxability of shipping charges varies by state. Some states tax shipping if it’s combined with handling or if it’s not separately stated, while others don’t tax it at all if stated separately. Check your state’s tax department website.
- How do I pay use tax?
- Most states allow you to report and pay use tax on your annual state income tax return or through a separate use tax form. Our guide on filing use tax can help.
- Is the tax rate the same everywhere?
- No, sales and use tax rates vary by state, county, and even city. Our Sales and Use Tax Calculator requires you to input the applicable rate.
- What if I buy something in a state with no sales tax but live in a state with sales tax?
- If you buy something in a no-sales-tax state (like Oregon) and bring it back to your home state (with sales tax) for use, you are technically supposed to pay use tax to your home state.
- Can I use this Sales and Use Tax Calculator for services?
- Yes, if the services are taxable in your jurisdiction. The taxability of services varies greatly by state.
- What happens if I don’t pay use tax?
- States are increasing efforts to collect use tax. If audited, you could be liable for back taxes, interest, and penalties.
