# About This Calculator

Sales tax is a consumption tax imposed by governments on the sale of goods and services. In the United States, sales tax rates vary significantly by state, county, and city, ranging from 0% (in states like Oregon and New Hampshire) to over 10% in some California cities. Understanding sales tax helps you budget accurately and avoid checkout surprises.

Sales tax is typically added at the point of purchase and collected by retailers who then remit it to the government. The tax applies to most tangible goods, though many states exempt groceries, prescription medications, and clothing. Services may or may not be taxed depending on the jurisdiction.

The calculation is straightforward: multiply the pre-tax price by the tax rate (as a decimal), then add that amount to the original price. For example, a $100 item with 8% tax costs $108 total ($100 + $8). This simple calculation helps you determine your actual out-of-pocket cost before reaching the register.

This calculator is essential for budgeting purchases, comparing prices across different tax jurisdictions, verifying receipts, and understanding the true cost of items. It's particularly useful for online shopping where tax may not be displayed until checkout, or when shopping in unfamiliar locations.

How To Use

  1. Enter net price.

Frequently Asked Questions

Why do sales tax rates vary so much by location?+

Sales tax is set at state, county, and city levels, creating combined rates. For example, California has 7.25% state tax, but cities can add local taxes, resulting in rates up to 10.75%. Each jurisdiction sets rates based on local budget needs and economic policy.

Are there items that are tax-exempt?+

Yes, exemptions vary by state. Common exemptions include: groceries (in most states), prescription medications, medical devices, clothing (in some states like Pennsylvania), and sometimes textbooks. Prepared food is usually taxed even if groceries aren't.

How do I calculate the original price if I only know the total with tax?+

Divide the total by (1 + tax rate as decimal). For example, if the total is $108 with 8% tax: $108 / 1.08 = $100 original price. This reverse calculation helps verify receipts or determine pre-tax prices.

Do I pay sales tax on online purchases?+

Usually yes, especially after the 2018 Supreme Court ruling. Most major retailers now collect sales tax based on your shipping address. Some small businesses may not collect tax, but you're technically required to report and pay 'use tax' on your tax return.

Which states have no sales tax?+

Five states have no statewide sales tax: Alaska, Delaware, Montana, New Hampshire, and Oregon. However, Alaska allows local sales taxes. These states typically compensate with higher income or property taxes.
