When customers buy something in the US, the sticker price typically won’t be the final price they pay. Customers may need to pay an extra charge at the checkout called sales tax.
Calculating sales tax can be complex because the rate depends on your location and what product or service you’re selling. Some products are exempt, while others require a higher amount.
In this article, we’ll help you understand sales tax, a few more important terms and the obligations by state.
What is sales tax?
Sales tax is a percentage of a sale that goes to a governing body for goods and services sold within its jurisdiction.
In the US, sales tax is a one-time tax levied by state and county governments that is charged to the end consumer (the taxpayer) at the point of sale.
Most businesses must pay taxes to their state or municipality on top of their earnings, so they pass the amount on to the customer. If your business buys products for resale, you’ll pay general sales tax and recover the amount when you sell to the end consumer.
Each Department of Revenue governs these taxes at the state level, so the amounts differ depending on where you sell or buy from. Local counties may also add an extra percentage to a statewide “base rate” to create a “combined rate”.
For example, the base sales tax rate in Illinois is 6.25%. However, the overall combined rate can be as high as 11.5% in areas like Cook County, which has 5.25% added on top.
5 sales tax rate terms you need to know about
While sales tax may sound simple enough, there are a few other processes to get your head around.
Learn the meaning of these five sales tax rate terms.
Excise tax
Excise taxes are for specific goods and services (e.g., cigarettes, alcohol, airline tickets) that state and federal governments can levy.
For example, the US government’s Internal Revenue Service (the IRS) controls gasoline taxes.
The government may impose excise tax on products or services that are likely to cause unintended consequences (not reflected in the sale price).
For example, the medical impact and long-term cost of smoking mean cigarettes fall within this remit.
Tax situs
“Situs” is Latin for “site” or “position”. In tax terms, it means the location where a taxing event happens.
Before e-commerce and online marketplace sellers, this would refer to the point of sale. However, determining tax situs now involves multiple sites when dealing with digital purchases.
For example, customers may purchase products from stores outside of their residential state (e.g., a book from an online shop in Texas that gets shipped to a house in New York).
Tax situs get complicated when considering marketplaces like Amazon and eBay, so it’s wise to seek out an expert if you’re setting up a business that involves selling through one of these portals.
Economic nexus
While “nexus” usually means having a physical presence, it now refers to any business with an economic presence in a particular state.
Before the e-commerce and remote seller boom, only companies with stores, offices, warehouses or representatives in specific states were liable for sales tax.
However, governments were losing billions of dollars in tax collection.
In response, new precedents meant even online businesses were chargeable for sales tax after they hit a set number of transactions, total sales or level of selling activity.
Use tax
Use taxes are conditional sales taxes consumers must pay when purchasing goods or services from locations without sales tax.
A use tax rate is usually determined by where a buyer intends to use their purchases.
For example, if you buy a car in Montana (that has no statewide sales tax) and take it home (out of state) to North Carolina, you’ll pay North Carolina’s rate of sales tax for “using” the car there.
Value-added tax (VAT)
The US doesn’t use value-added tax (VAT) but it’s another way of calculating tax on the sale of goods and services. It’s important to know about if you do business overseas, such as with the United Kingdom.
Instead of consumers paying the total taxable amount at the point of purchase, different parties pay a flat amount (which works out as varying portions) throughout the supply chain.
Here’s how it can work:
A manufacturer pays 20% VAT on raw materials for a product
Another manufacturer pays 20% VAT for a more expensive small part made of those raw materials
A retailer pays 20% VAT when purchasing the finished product
Consumers pay 20% VAT when buying from the retailer at an inflated price
If your business uses European goods or suppliers, you may have an obligation to pay VAT, so be sure you understand how it works.
How to calculate sales tax in 17 US states
In the US, states charge sales tax on most goods and services to fund public schools, infrastructure, emergency services and public transportation.
No matter which state your business is operating in, the formula for calculating sales tax will be the same:
Product selling price × sales tax rate percentage
If a business bases itself in a state with a 7% sales tax rate and sells software for $1,000, every transaction will be liable for $70 in sales tax.
When the business adds tax to the final price, the customer will pay $1,070 for the software.
If your business operates in several states, you must also consider the sales tax nexus (the rule that states you may be subject to the rate of one state even if your headquarters are in another).
Whether you need to collect sales tax at all depends on what you’re selling, as not all products and services are subject to sales tax laws.
Most states provide exemptions for groceries and utilities, but they’ll tax items like restaurant food bills, consulting services and digital products.
Each state also has different sales tax return rules, which means you’ll need to check:
When to file. Depending on where your business operates, filing frequency for tax information will be monthly, quarterly or annually.
How to file. Some states will have electronic filing options in place, while others require you to send tax forms through the mail.
How to pay. Check to see if you can pay using a credit or debit card or if you’ll have to write a check.
The best way to ensure your tax filings are accurate is to research the state(s) your business operates in. Calculate any base or minimum combined sales tax rates and use tax returns you are liable for.
Otherwise, you can hire the help of a tax professional who can answer FAQs and more complex issues.
