What is Sales Tax? A Simple Explanation
Sales tax is a consumption tax imposed by state and local governments on the sale of goods and services. When you buy a product at a retail store, the sales tax is added to the price of the item at the point of sale. The retailer then collects this tax and remits it to the government.
The Difference Between Sales Tax, Use Tax, and Excise Tax
Sales Tax: A tax on the sale of goods and services.
Use Tax: A tax on the use, storage, or consumption of goods or services when sales tax has not been paid. This often applies to items purchased online or out-of-state.
Excise Tax: A tax on a specific type of good, such as gasoline, tobacco, or alcohol.
How to Calculate Sales Tax: The Formula
The formula for calculating sales tax is simple:
Sales Tax = Purchase Price x Sales Tax Rate
Total Price = Purchase Price + Sales Tax
Example:
Let's say you're buying a new laptop for $1,000 in a city with a sales tax rate of 8%.
Sales Tax: $1,000 x 0.08 = $80
Total Price: $1,000 + $80 = $1,080
State-by-State Sales Tax Guide
Sales tax rates vary significantly from state to state, and even from city to city. Here's a breakdown of sales tax rates across the United States.
Sales Tax for Online Businesses
The rules for collecting sales tax for online businesses have changed significantly in recent years. The 2018 Supreme Court case South Dakota v. Wayfair ruled that states can charge tax on purchases made from out-of-state sellers, even if the seller does not have a physical presence in the taxing state.
This concept is known as economic nexus. Each state has its own threshold for economic nexus, which is usually based on the seller's sales revenue or number of transactions in that state.
Sales Tax on Shipping and Handling
Whether or not sales tax is charged on shipping and handling fees depends on the state.
Some states consider shipping and handling to be part of the total sale price and therefore taxable.
Other states consider shipping and handling to be a separate service and therefore not taxable.
It's crucial to check the rules for each state where you do business.
Sales Tax Exemptions
Not all goods and services are subject to sales tax. Common exemptions include:
Groceries: Most states exempt unprepared food items from sales tax.
Prescription Drugs: Prescription medications are typically exempt from sales tax.
Sales to Non-Profits: Sales to registered non-profit organizations are often exempt.
How to Get a Sales Tax Exemption Certificate
If your business qualifies for sales tax exemptions, you'll need to obtain a sales tax exemption certificate from your state's department of revenue. This certificate allows you to purchase items for resale or for use in your business without paying sales tax.
What Happens if You Don't Pay Sales Tax?
Failing to collect and remit sales tax can have serious consequences for a business, including:
Penalties and Fines: States can impose hefty penalties and fines for non-compliance.
Back Taxes: You may be required to pay back taxes, plus interest.
Legal Action: In severe cases, the state may take legal action against your business.
