In this blog, we will delve into the critical aspects of sales tax nexus for small business eCommerce.

Understanding Sales Tax Nexus

Sales tax nexus refers to the connection or presence that a business has within a specific state or jurisdiction. When a nexus is established, the business is obligated to collect and remit sales tax on transactions within that jurisdiction. Historically, physical presence, such as a brick-and-mortar store, office, or warehouse, determined nexus. However, the advent of eCommerce and the expansion of online transactions have led to new criteria to establish sales tax nexus for eCommerce businesses.

Common factors that can trigger sales tax nexus for online stores include:

1. Physical Presence: As with traditional businesses, maintaining an office, warehouse, or retail location within a state can establish sales tax nexus for eCommerce businesses.

2. Remote Employees: Having remote employees in different states can create nexus, requiring businesses to collect and remit sales tax in those states.

3. Fulfillment Services: Using third-party fulfillment centers, such as Amazon FBA, can establish nexus, as storing inventory in warehouses across different states can produce a nexus connection.

Understanding the factors that influence sales tax nexus for your eCommerce business is essential in determining your sales tax obligations across various states.

Economic Nexus Thresholds

The 2018 South Dakota v. Wayfair Supreme Court decision revolutionized the concept of sales tax nexus for eCommerce businesses by introducing economic nexus principles. The ruling determined that physical presence was no longer the sole criterion for sales tax nexus. Instead, meeting specific sales or transaction thresholds within a state could also create a taxable presence.

As a result, most states have adopted economic nexus thresholds, which typically include:

1. Sales Thresholds: A specific dollar amount of total sales within a state, often between $100,000 and $500,000 annually.

2. Transaction Thresholds: A set number of individual transactions taking place within a state, often ranging from 100 to 200 transactions per year.

It's important to stay updated on the economic nexus thresholds in each state where your eCommerce business operates, as they can change over time and create new sales tax obligations.

Complying with Sales Tax Obligations

To ensure compliance with sales tax obligations in various states, as determined by physical or economic nexus, small business eCommerce owners should follow these critical steps:

1. Register for Sales Tax Permits: Obtain necessary sales tax permits in each state where nexus is established. Registration requirements may vary by jurisdiction, but generally, you'll need to provide business identification information, tax identification numbers, and projected sales information.

2. Collect Sales Tax: Implement sales tax collection mechanisms on your online store. Use eCommerce platforms or third-party tax software that can automatically calculate sales tax based on the customer's location.

3. File Sales Tax Returns: Submit timely sales tax returns in each state where nexus exists. The frequency of filing varies by jurisdiction and may be monthly, quarterly, or annually, depending on sales volume.

4. Remit Collected Taxes: Transfer the collected sales taxes to the appropriate tax authorities in each state as required.

Complying with these obligations can help your eCommerce business avoid potential penalties, interest payments, and audits relating to sales tax issues.

Navigating Sales Tax Exemptions

Sales tax exemptions can provide eCommerce businesses with valuable opportunities for growth and potential tax savings. These exemptions typically arise from three primary sources:

1. Product-Based Exemptions: Certain products, such as food, clothing, or medications, may be exempt from sales tax in specific states.

2. Buyer-Based Exemptions: Some customers, such as nonprofit organizations, schools, or government entities, may be exempt from paying sales tax on eligible purchases.

3. Use-Based Exemptions: Exemptions may apply when products are intended for specific uses, such as manufacturing, research, or agricultural purposes.

To benefit from these exemptions, ensure that your online store is configured to accommodate sales tax exemptions and maintain proper documentation, such as exemption certificates, to validate exempt transactions.
