If you’re starting or running a business in the United States, one of the most important concepts you’ll encounter is Sales Tax. Unlike some countries with a national value-added tax (VAT), the US has a unique system where Sales Tax is state-controlled and varies widely depending on location.
In this guide, we’ll break down what Sales Tax is in the US, how it works, who must collect it, and what business owners need to do to remain compliant.
Definition: What Is Sales Tax?
Sales Tax is a state and local consumption tax charged on the sale of goods and certain services. It is collected by the seller at the point of purchase and then remitted to the state or local tax authority.
Key facts:
- There is no federal Sales Tax in the US.
- Rates, rules, and exemptions vary by state and local jurisdiction.
- Businesses with a nexus in a state are required to collect and remit Sales Tax.
🧾 Sales Tax is paid by the consumer but collected and reported by the business.
How Sales Tax Works in the US
The Sales Tax process involves three main steps:
- Collection – The seller charges the applicable Sales Tax rate at checkout.
- Reporting – The seller tracks and reports total sales and tax collected to the state.
- Remittance – The seller sends the collected tax to the state or local tax agency.
States That Do and Do Not Have Sales Tax
As of 2025, 45 states and the District of Columbia impose a Sales Tax.
Five states do not have a statewide Sales Tax:
- Alaska (local municipalities may charge it)
- Delaware
- Montana
- New Hampshire
- Oregon
However, even in states without a general Sales Tax, there may still be other taxes on specific goods or services.
Sales Tax Rates
Sales Tax rates can vary dramatically depending on where the buyer is located. There are:
- State rates – Set by each state
- Local rates – Added by counties or cities
Combined rates can range from under 5% to over 10%.
What Is Nexus?
To determine whether you need to collect Sales Tax in a particular state, you must understand nexus — a legal term that means a business has a significant connection to a state.
Two main types of nexus:
- Physical nexus: Having an office, store, warehouse, or employees in the state.
- Economic nexus: Reaching a certain sales revenue or transaction volume in the state, even without physical presence.
What Transactions Are Taxable?
The rules vary by state, but Sales Tax typically applies to:
- Tangible goods (electronics, furniture, clothing, etc.)
- Certain services (repairs, accommodations, digital products in some states)
Some states exempt:
- Groceries
- Prescription medicine
- Educational services
Always check each state’s taxability rules before selling.
How to Register to Collect Sales Tax
If you determine you have nexus in a state:
- Register for a Sales Tax permit with that state’s Department of Revenue.
- Receive your Sales Tax ID number.
- Set up your sales system to collect the correct rates.
⚠️ It is illegal to collect Sales Tax without being registered.
Filing and Remitting Sales Tax
Once registered, you’ll need to:
- File returns (monthly, quarterly, or annually) depending on state requirements.
- Remit the tax you collected to the correct agency.
- Keep accurate records in case of an audit.
Common Mistakes to Avoid
- Failing to register in states where you have nexus
- Charging the wrong rate or forgetting to update rates
- Not collecting exemption certificates from resellers or exempt organizations
- Missing filing deadlines
Sales Tax and Online Sales
eCommerce sellers must be aware of economic nexus laws. Since the South Dakota v. Wayfair decision in 2018, many states require out-of-state sellers to collect Sales Tax once they exceed a sales threshold.

- Penalties and interest
