As an online seller, navigating the complex world of sales tax can be a daunting task. With the rapid growth of eCommerce and the ever-changing tax laws, it's crucial to understand your sales tax obligations to avoid penalties and maintain compliance.

This in-depth guide will walk you through the essentials of sales tax for online selling, including key concepts like nexus, economic thresholds, and state-specific requirements.

‍

What is Sales Tax?

Definition and Basic Principles

Sales tax is a consumption tax levied by state and local governments on the sale of goods and services. Unlike value-added tax (VAT), which is collected at each stage of the supply chain, sales tax is only collected at the point of sale to the end consumer.

The seller is responsible for collecting the tax from the customer and remitting it to the appropriate tax authorities.

Sales Tax vs. VAT: Understanding the Difference

While both sales tax and VAT are consumption taxes, they differ in their application and collection methods. Sales tax is imposed only on the final sale to the consumer, and the tax rate is based on the location of the sale.

On the other hand, VAT is collected at each stage of the supply chain, with businesses able to claim credits for the VAT they pay on purchases. As an online seller, it's essential to understand which tax system applies to your business based on your location and the locations of your customers.

Understanding Sales Tax Nexus

Physical Nexus Explained

Sales tax nexus refers to the connection between a business and a state that triggers the obligation to collect and remit sales tax.

Traditionally, physical nexus was established by having a physical presence in a state, such as a store, warehouse, or employees.

For example, if your online shopping business has a warehouse in California, you likely have physical nexus in that state and must collect sales tax from your California customers.

Examples of Physical Nexus Triggers

Having a physical store, office, or warehouse in a state
Storing inventory in a state, even if it's in a third-party fulfillment center
Having employees, sales representatives, or contractors working in a state
Attending trade shows or events in a state (in some cases)

Economic Nexus: The Modern Criteria

In the wake of the 2018 Supreme Court decision in South Dakota v. Wayfair, Inc., many states have introduced economic nexus laws that require online sellers to collect sales tax based on their sales volume or revenue in the state, regardless of physical presence.

These thresholds vary by state, so it's crucial to stay informed about the specific requirements in the states where you sell.

Volume and Revenue Thresholds

Economic nexus thresholds are typically based on sales volume or revenue generated in a state. For example, a state may require online sellers to collect sales tax if they make more than $100,000 in sales or 200 transactions in the state annually. Crossing these thresholds can trigger sales tax obligations, so it's crucial to monitor your own internet sales tax amount and revenue closely.

Examples of Economic Nexus Thresholds

South Dakota: $100,000 in annual sales or 200 transactions
Pennsylvania: $100,000 in annual sales
Massachusetts: $100,000 in annual sales and 100 transactions

Marketplace Facilitator Laws

Marketplace facilitator laws have emerged as a response to the growth of online marketplaces like Amazon and eBay. These laws shift the responsibility for collecting and remitting sales tax from individual sellers to the marketplace platform.

However, it's still important for sellers to understand their obligations and ensure compliance with these laws.

Examples of Marketplace Facilitator Laws

Amazon: Collects and remits sales tax on behalf of sellers in states with marketplace facilitator laws
eBay: Collects and remits sales tax on behalf of sellers in some states, while in others, the seller is responsible
Etsy: Collects and remits sales tax on behalf of sellers in states with marketplace facilitator laws

Criteria for Collecting Sales Tax Online

Geographical Considerations

The location of both the seller and the buyer play a significant role in determining sales tax obligations. Generally, if you have nexus in a state and sell to customers in that state, you must collect sales tax. However, some states have destination-based tax laws, meaning that the tax rate is determined by the customer's location rather than the seller's.

Origin-Based vs. Destination-Based Sales Tax

Origin-based sales tax: The tax rate is determined by the seller's location, and the seller collects tax based on that rate, regardless of where the customer is located.
Destination-based sales tax: The tax rate is determined by the customer's location, and the seller must collect tax based on the customer's address.

Product and Service Specifics

Not all products and services are subject to sales tax, and tax rates can vary depending on the type of item sold. For example, some states exempt certain necessities like food and clothing from sales tax, while others impose higher sales tax rates on luxury goods. It's important to research the specific tax treatment of your products or services in each state where you have nexus.

Examples of Product and Service Tax Differences

Clothing: Exempt from sales tax in some states, like Pennsylvania and New Jersey, but subject to tax in others, like New York and California
Food: Generally exempt from sales tax when sold for home consumption, but may be taxed when sold in restaurants or as prepared meals
Digital goods: Taxability varies widely by state, with some states taxing all digital goods, others taxing only specific types, and some not taxing them at all

Common Sales Tax Mistakes and How to Avoid Them

Ignoring Sales Tax Nexus

One of the most common mistakes online sellers make is failing to recognize when they have established sales tax nexus in a state. Ignoring nexus can lead to significant penalties and interest charges if you are later found to have had a tax obligation.

How to Avoid This Mistake

Regularly review your business activities in each state, including sales volume, physical presence, and economic nexus thresholds
Keep track of changing nexus laws and regulations in the states where you sell
Consult with a tax professional or use sales tax software to help determine your nexus obligations

Failing to Register for Sales Tax Permits

Once you have determined that you have nexus in a state, you must register for a sales tax permit before you can begin collecting and remitting taxes. Failing to register and pay sales tax due can result in penalties and legal consequences.

How to Avoid This Mistake

Promptly register for a sales tax permit in each state where you have nexus
Keep your registration information up-to-date, including any changes to your business structure or contact details
Understand and comply with any additional requirements, such as posting a bond or prepaying sales tax

Collecting the Wrong Amount of Sales Tax

Collecting the incorrect amount of sales tax can happen due to misunderstanding product taxability, applying the wrong tax rate, or failing to account for local and county sales taxes due. Over-collecting tax can lead to customer dissatisfaction, while under-collecting can result in penalties and interest charges.

How to Avoid This Mistake

Thoroughly research the taxability of your products and services in each state
Use geolocation technology or address validation to ensure you are applying the correct state and local tax rates
Regularly review and update your tax settings in your eCommerce platform or sales tax software

Mishandling Sales Tax Exemptions

Improperly managing sales tax exemptions, such as those for resale or non-profit organizations, can lead to errors in tax collection and reporting. Failing to obtain and maintain valid exemption certificates can also result in penalties during an audit.

How to Avoid This Mistake

Obtain and retain valid exemption certificates for all tax-exempt sales
Regularly review and update your exemption certificate records
Train your staff on the proper handling of tax-exempt transactions

Missing Sales Tax Filing and Payment Deadlines

Each state has its own filing frequencies and due dates for sales tax returns and payments. Missing these deadlines to file returns can result in penalties, interest charges, and even legal consequences.

How to Avoid This Mistake

Know the filing frequencies and due dates for each state where you have nexus
Set reminders or use calendar tools to ensure you don't miss any deadlines
Consider using sales tax automation software that can handle filing and remittance on your behalf

Leverage technology and automation to streamline sales tax management
Foster a culture of compliance and prioritize staying informed and educated about sales tax obligations

What should I do if I realize I have been collecting the wrong amount of sales tax?
If you discover that you have been collecting the incorrect amount of sales tax, you should first determine the extent of the error and the affected states.
