U.S. Sales Tax: What You Need to Know and How to Avoid Common Pitfalls

Sales tax is an essential part of doing business in the United States, yet it can be complex and vary significantly from state to state. Understanding how sales tax works, who is responsible for collecting it, and how to remain compliant is crucial for businesses operating in the U.S. This guide will cover the key aspects of U.S. sales tax and provide tips on how to avoid common mistakes.

What is Sales Tax?

Sales tax is a state-imposed tax on the sale of goods and certain services. Unlike value-added tax (VAT), which is applied at each stage of production, sales tax is typically collected at the point of sale by the seller and then remitted to the appropriate state tax authority.

Who Needs to Collect Sales Tax?

A business is required to collect and remit sales tax if it has sales tax nexus in a particular state. A sales tax nexus is established through:

• Physical presence – Having an office, warehouse, or store in a state.
• Economic nexus – Surpassing a certain threshold of sales or transactions in a state (e.g., $100,000 in revenue or 200 transactions per year).
• Affiliate nexus – Working with affiliates or subsidiaries that operate in a state.
• Marketplace facilitator laws – Online platforms like Amazon or eBay may be responsible for collecting sales tax on behalf of sellers.

Sales Tax Rates and Rules Vary by State

• Unlike federal taxes, sales tax is regulated at the state and local level, which means:
• Sales tax rates differ between states (ranging from 0% to over 10%).
• Some states have additional local sales taxes imposed by counties or cities.
• Certain goods and services may be exempt from sales tax.
• Some states implement tax holidays where sales tax is waived on specific items for a limited period.

Common Sales Tax Mistakes and How to Avoid Them

Failing to comply with sales tax laws can lead to penalties and audits. Here are some common mistakes businesses make and how to prevent them:

1. Not Registering for a Sales Tax Permit – If you have nexus in a state, you must apply for a sales tax permit before collecting tax.
2. Charging the Wrong Sales Tax Rate – Make sure to stay updated with state and local tax rates.
3. Failing to File Sales Tax Returns on Time – Even if you didn’t collect any sales tax, you may still need to file a zero-return report.
4. Misclassifying Taxable and Non-Taxable Items – Some products (e.g., groceries, prescription drugs) may be tax-exempt in certain states.
5. Ignoring Economic Nexus Laws – Many states require remote sellers to collect sales tax once they meet certain thresholds.
6. Not Keeping Proper Sales Tax Records – Maintaining detailed records of sales, tax collected, and exemption certificates is crucial for audits.
