Do I Need to Collect Sales Tax? A Comprehensive Guide

The million-dollar question for any business owner selling goods or certain services: Do I need to collect sales tax? The short, bittersweet answer is, it depends. Sales tax laws are notoriously complex and vary significantly from state to state, and even sometimes within states based on local jurisdictions. Generally, if you have a nexus (a significant connection) with a state and sell taxable goods or services in that state, you’re likely required to collect sales tax from your customers and remit it to the appropriate taxing authority.

Understanding Sales Tax Nexus

Nexus is the crucial foundation upon which sales tax obligations are built. Without nexus, you generally have no duty to collect sales tax in a particular state. However, defining “nexus” is where things get tricky. It’s no longer as simple as having a physical storefront in a state.

Physical Presence Nexus

This is the traditional understanding of nexus and still applies. Physical presence nexus is established when your business has a physical presence in a state, such as:

A store or office: Owning or leasing a physical retail location or an office.
A warehouse or distribution center: Storing inventory or fulfilling orders from a location within the state.
Employees or salespeople: Having employees who work in the state, even remotely.
Independent contractors: Using independent contractors who solicit sales on your behalf.

Economic Nexus

The landmark Supreme Court case South Dakota v. Wayfair, Inc. (2018) revolutionized sales tax, introducing the concept of economic nexus. This means that even without a physical presence, you can still be required to collect sales tax in a state based solely on your sales volume or revenue.

Thresholds: Each state with economic nexus laws sets a threshold for sales or revenue. Common thresholds are $100,000 in sales or 200 separate transactions within a calendar year. If you exceed these thresholds, you’ve established economic nexus.
Monitoring Sales: It’s crucial to monitor your sales activity in each state, even if you don’t have a physical presence. Exceeding the threshold triggers the requirement to register and collect sales tax.

Affiliate Nexus, Click-Through Nexus, and Marketplace Nexus

Beyond physical and economic nexus, several other nexus types exist:

Affiliate Nexus: Some states consider you to have nexus if you have affiliates (e.g., websites) in the state that refer customers to your business.
Click-Through Nexus: Similar to affiliate nexus, this arises if you pay commissions to websites located in the state for sales generated through links on their sites.
Marketplace Nexus: This addresses sales made through online marketplaces like Amazon or Etsy. Many states have marketplace facilitator laws, which generally require the marketplace to collect and remit sales tax on behalf of third-party sellers using their platform. However, it is important to determine if the marketplace is collecting sales tax, and it is important to keep records and evidence of these sales.

Taxable Goods and Services

Even with nexus, you only need to collect sales tax on taxable goods and services. Sales tax laws define what is considered taxable.

Tangible Personal Property: Generally, tangible personal property (physical items you can touch) is taxable.
Services: The taxability of services varies significantly by state. Some states tax very few services, while others tax a wide range. Common taxable services include installation, repairs, and certain professional services.
Exemptions: Many states offer exemptions from sales tax for specific types of goods or customers. Common exemptions include groceries, prescription medications, and sales to certain non-profit organizations.

Sales Tax Registration and Collection

Once you determine you have nexus and are selling taxable goods or services in a state, you must register with the state’s taxing authority.

Registration: The registration process typically involves providing your business information, obtaining a sales tax permit or license, and agreeing to file and remit sales tax returns.
Collection: You are responsible for collecting the correct sales tax rate from your customers at the point of sale. This rate may include state, county, and local taxes.
Filing and Remitting: You must file sales tax returns on a regular basis (monthly, quarterly, or annually, depending on your sales volume) and remit the collected taxes to the state.

Frequently Asked Questions (FAQs)

1. I only sell online. Do I still need to worry about sales tax?

Yes. The Wayfair decision established that economic nexus applies to online sales. If you meet a state’s economic nexus threshold (typically $100,000 in sales or 200 transactions), you must collect sales tax in that state.

2. How do I determine the correct sales tax rate to charge?

Sales tax rates can vary based on the buyer’s location. Many states have destination-based sales tax, meaning you charge the rate where the customer receives the goods. Use sales tax software or online rate finders to determine the accurate rate.

3. What happens if I don’t collect sales tax when I should?

Failure to collect sales tax can result in significant penalties, including back taxes, interest, and fines. It’s crucial to comply with sales tax laws to avoid legal and financial repercussions.

4. I sell on Amazon. Does Amazon collect sales tax for me?

Amazon may collect and remit sales tax for you in certain states due to marketplace facilitator laws. However, you should verify which states Amazon is collecting for and ensure you are compliant in all states where you have nexus. Keep meticulous records.

5. How often do I need to file sales tax returns?

The filing frequency depends on the state and your sales volume. Most states require monthly, quarterly, or annual filings. Check with each state’s taxing authority for specific requirements.

6. What is sales tax nexus?

Sales tax nexus is a legal term that refers to the connection between your business and a state that triggers the obligation to collect and remit sales tax in that state.

7. What are some common sales tax exemptions?

Common exemptions include sales of grocery items, prescription drugs, and sales to certain non-profit organizations. Exemptions vary by state.

8. Can I deduct the sales tax I collect from my income taxes?

No. Sales tax you collect is held in trust for the state and is not considered income. Therefore, it’s not deductible.

9. What’s the difference between sales tax and use tax?

Sales tax is collected by the seller when a taxable item is sold. Use tax is paid by the buyer when sales tax was not collected at the time of purchase (e.g., when buying online from an out-of-state vendor).

10. How do I register for a sales tax permit?

You can register for a sales tax permit (also known as a sales tax license) through each state’s department of revenue website. The process typically involves providing business information and contact details.

11. What records do I need to keep for sales tax purposes?

Maintain detailed records of all sales transactions, including dates, amounts, locations, tax collected, and any exemptions claimed. Keep these records for at least the period required by state law, which is usually several years.

12. I think I made a mistake on a sales tax return. What should I do?

Contact the state’s taxing authority immediately. You may need to file an amended return to correct the error. Promptly addressing mistakes can help minimize penalties.

Navigating the complexities of sales tax can be daunting. Consulting with a qualified tax professional is highly recommended to ensure compliance and avoid costly mistakes. Keeping informed and proactive is key to managing your sales tax obligations effectively.
