Internet Sales Tax: A Comprehensive Guide for Online Sellers

The rise of e-commerce has transformed how businesses operate, enabling entrepreneurs to reach customers across state lines and even internationally. However, with this opportunity comes the challenge of navigating internet sales tax laws, which can be a daunting task for online sellers. In the United States, sales tax obligations are primarily governed by state and local authorities, and the landscape has shifted significantly since the landmark South Dakota v. Wayfair Supreme Court decision in 2018. This ruling expanded the ability of states to impose sales tax on online transactions, even for businesses without a physical presence in a state. For small and medium-sized businesses, understanding these laws is critical to staying compliant and avoiding costly penalties.

This comprehensive guide provides an in-depth exploration of internet sales tax laws, offering practical guidance, examples, and strategies to help online sellers navigate this complex terrain.

Understanding Internet Sales Tax: The Basics

Sales tax is a consumption tax imposed by state and local governments on the sale of goods and services. In the U.S., sales tax is primarily a state-level responsibility, with 38 states also allowing localities, such as cities and counties, to impose their own sales taxes. The complexity arises because each state and locality may have different tax rates, exemptions, and rules about what constitutes a taxable transaction. For online sellers, the challenge is determining when and where they are required to collect and remit sales tax for transactions that cross state lines.

Historically, states could only require businesses with a physical presence—such as a store, office, or warehouse—in their jurisdiction to collect sales tax. This physical presence rule limited states’ ability to tax online sales, leading to significant revenue losses as e-commerce grew. The South Dakota v. Wayfair decision in 2018 changed this by eliminating the physical presence requirement, allowing states to tax remote sellers based on economic nexus. This shift has made it essential for online businesses to understand their tax obligations in every state where they sell products or services.

What is Tax Nexus and Why Does It Matter?

At the heart of internet sales tax compliance is the concept of tax nexus, which determines whether a business has a sufficient connection to a state to be subject to its tax laws. A nexus can be established through various activities, including:

• Maintaining a physical office, warehouse, or other place of business in a state
• Employing workers, including independent contractors, salespeople, or agents, in a state
• Storing inventory in a state, even if it’s in a third-party warehouse
• Selling or shipping products to customers in a state, particularly if sales volume or transaction counts exceed state-defined thresholds

Before the Wayfair decision, only businesses with a physical presence were subject to sales tax obligations. Now, economic nexus allows states to require remote sellers—those without a physical presence but with significant sales activity in a state—to collect and remit sales tax. Each state sets its own economic nexus thresholds, typically based on gross sales or the number of transactions in a given period.

For example, a small online retailer based in Texas that ships products to customers in California may establish economic nexus in California if their sales exceed the state’s threshold. This means they must register with the state, collect sales tax on applicable transactions, and remit those taxes to California’s taxing authority.

States Without Sales Tax: A Brief Exception

Not all states impose a sales tax, which provides some relief for online sellers operating in those jurisdictions. The five states with no statewide sales tax are:

• Alaska
• Delaware
• Montana
• New Hampshire
• Oregon

However, Alaska presents a unique case. While there is no statewide sales tax, certain localities, such as Anchorage and Juneau, impose local sales taxes. Online sellers in these states, or those selling into Alaska localities, should verify local tax requirements to ensure compliance.

Economic Nexus Thresholds: State-by-State Variations

As of 2025, 45 states and the District of Columbia have implemented economic nexus laws requiring remote sellers to collect and remit sales tax. These laws vary significantly, with each state defining its own thresholds for what constitutes a large seller subject to these obligations. Thresholds are typically based on one or both of the following:

• Gross sales or revenue (e.g., taxable sales, retail sales, or total sales)
• Number of transactions (e.g., individual sales or orders)

Below is a table illustrating the diversity of economic nexus thresholds in select states:

These thresholds mean that smaller online sellers with limited sales in a state may not meet the criteria for economic nexus and are therefore exempt from collecting sales tax. For instance, a home-based Etsy seller with $50,000 in annual sales to California customers would not need to collect sales tax in California, as they fall below the $500,000 threshold. However, if their sales grow to exceed this threshold, they must register and comply with California’s sales tax laws.

How the Wayfair Decision Changed the Landscape

The South Dakota v. Wayfair decision was a game-changer for internet sales tax. Prior to 2018, states were limited by the physical presence rule established in the 1992 Quill Corp. v. North Dakota case, which required a business to have a physical location in a state to be subject to its sales tax laws. This rule allowed many online retailers to avoid collecting sales tax, creating an uneven playing field with brick-and-mortar stores.

In the Wayfair case, the Supreme Court ruled that states could require remote sellers to collect sales tax based on economic activity in the state, even without a physical presence. South Dakota’s law, which set a threshold of $100,000 in sales or 200 transactions annually, was upheld as a reasonable standard. This decision prompted nearly all states with sales taxes to adopt similar economic nexus laws, significantly expanding the scope of sales tax compliance for online businesses.

For example, consider an online clothing retailer based in Georgia that sells to customers nationwide. Before Wayfair, they only collected sales tax for Georgia customers. Now, if they sell $150,000 worth of clothing to Florida customers in a year, they must register with Florida’s taxing authority, collect sales tax on those transactions, and remit the taxes to the state.

Steps to Ensure Compliance with Internet Sales Tax Laws

Navigating internet sales tax requirements can feel overwhelming, especially for small business owners who may lack the resources of larger corporations. However, by following a structured approach, online sellers can manage their obligations effectively. Here are key steps to ensure compliance:

1. Determine Your Nexus in Each State

The first step is to identify where your business has nexus, whether physical or economic. Review your business activities, including:

• Locations of offices, warehouses, or other facilities
• Where your employees or contractors work
• States where you store inventory (e.g., through third-party logistics providers like Amazon FBA)
• Sales and transaction volumes in each state

Use state-specific resources, such as the website of the state’s department of revenue or taxing authority, to check economic nexus thresholds. For example, an online seller shipping to Illinois must collect sales tax if they have $100,000 in sales or 200 transactions in the state over the past 12 months.

2. Register for Sales Tax Permits

If you meet the nexus threshold in a state, you must register for a sales tax permit with that state’s taxing authority. This process typically involves:

• Submitting an application through the state’s tax portal
• Providing business details, such as your Employer Identification Number (EIN) and sales data
• Paying a registration fee (varies by state)

For instance, a business selling software subscriptions might need to register in New York if they exceed $500,000 in sales and 100 transactions in the state. Registration ensures you can legally collect and remit sales tax.

3. Understand Taxable Products and Services

Not all products and services are taxable in every state. For example:

• Clothing is exempt from sales tax in states like New Jersey and Pennsylvania but taxable in California.
• Digital products, such as software or e-books, are taxable in some states but not others.
• Services, like consulting or graphic design, may be taxable depending on the state’s laws.

Research the taxability of your products or services in each state where you have nexus. State taxing authority websites provide detailed lists of taxable and exempt items.

4. Calculate and Collect Sales Tax

Once registered, you must charge the correct sales tax rate on taxable transactions. This can be complex because rates vary not only by state but also by locality. For example:

• In Colorado, the state sales tax rate is 2.9%, but local rates can push the combined rate as high as 11.2% in some cities.
• In New York City, the combined state and local rate is 8.875%.

To determine the correct rate, you need the customer’s ship-to address or, for digital products, their billing address. Sales tax software can automate this process by calculating rates based on geolocation.

5. File and Remit Sales Taxes

Each state has its own filing frequency (e.g., monthly, quarterly, or annually), depending on your sales volume. You’ll need to:

• Track sales tax collected for each state and locality
• File returns with the state’s taxing authority
• Remit the collected taxes by the due date

Missing deadlines or underpaying taxes can result in penalties and interest. For example, a California-based seller who fails to remit sales tax on $200,000 in taxable sales to Texas customers could face fines from the Texas Comptroller’s office.

6. Leverage Sales Tax Software

The complexity of managing sales tax across multiple states and localities makes manual tracking nearly impossible for most businesses. Sales tax software like Avalara, TaxJar, or Vertex can simplify compliance by:

• Calculating tax rates based on customer location
• Tracking nexus thresholds in real-time
• Automating tax collection at checkout
• Generating reports for filing returns
• Monitoring rate changes and exemptions

For example, an online retailer using TaxJar can integrate the software with their e-commerce platform (e.g., Shopify or WooCommerce) to automatically charge the correct tax rate and file returns with minimal effort.

7. Consider International Sales

If your business sells internationally, you may face additional tax obligations, such as Value-Added Tax (VAT) in Europe or Goods and Services Tax (GST) in countries like Canada or Australia. Sales tax software often includes tools to calculate and manage international taxes, ensuring compliance with global regulations.

Practical Examples of Internet Sales Tax Scenarios

To illustrate how internet sales tax works in practice, consider the following scenarios:

Scenario 1: Small Home-Based Business

Jane runs a small Etsy shop from her home in Oregon, selling handmade jewelry. She has $80,000 in total sales, with $20,000 from California customers and $10,000 from New York customers. Since Oregon has no sales tax, Jane doesn’t collect tax on in-state sales. Her sales in California and New York fall below those states’ economic nexus thresholds ($500,000 each), so she’s not required to collect sales tax in those states either. Jane can focus on growing her business without worrying about sales tax compliance for now.

Scenario 2: Growing E-Commerce Retailer

Mike operates an online sporting goods store based in Texas. In 2024, he records $600,000 in sales, including $150,000 to Florida customers and $200,000 to Illinois customers. Both states have economic nexus thresholds that Mike exceeds (Florida: $100,000; Illinois: $100,000 or 200 transactions). Mike must:

• Register for sales tax permits in Florida and Illinois
• Charge sales tax on taxable transactions in those states
• File returns and remit taxes according to each state’s schedule

To manage this, Mike uses Avalara, which integrates with his e-commerce platform to automate tax calculations and filings.

Scenario 3: Digital Products Seller

Sarah sells digital marketing courses from her office in Georgia. She has $300,000 in sales, with $120,000 from New York customers and 150 transactions. Since she exceeds New York’s economic nexus threshold ($500,000 or 100 transactions), she must register with New York’s taxing authority and collect sales tax on her digital products, which are taxable in New York. Sarah uses TaxJar to track her sales and ensure compliance.

Challenges and Pitfalls to Avoid

Complying with internet sales tax laws is not without challenges. Common pitfalls include:

• Failing to Track Nexus: Businesses may unknowingly exceed economic nexus thresholds in multiple states, leading to non-compliance.
• Miscalculating Tax Rates: Using incorrect rates or failing to account for local taxes can result in under- or over-collection.
• Missing Filing Deadlines: Late filings or payments can incur penalties and interest.
• Ignoring Exemptions: Not applying tax exemptions for certain products or customers (e.g., nonprofits) can lead to errors.

To avoid these issues, regularly review your sales data, consult with a tax professional, and invest in reliable sales tax software.

Additional Considerations for Online Sellers

Beyond the basics of sales tax compliance, online sellers should keep the following in mind:

• Marketplace Facilitator Laws: Many states have enacted laws requiring marketplace facilitators like Amazon, eBay, or Etsy to collect and remit sales tax on behalf of their sellers. If you sell through these platforms, check whether the marketplace handles tax collection for you.
• Sales Tax Holidays: Some states offer temporary sales tax holidays, during which certain products (e.g., school supplies or clothing) are exempt from tax. Be aware of these events to adjust your tax calculations.
• Audit Preparedness: States may audit businesses to ensure compliance. Maintain detailed records of sales, tax collected, and returns filed to prepare for potential audits.
• Customer Communication: Clearly communicate tax obligations to customers at checkout to avoid confusion or complaints about unexpected charges.

The Role of Sales Tax Software in Simplifying Compliance

Given the complexity of internet sales tax, investing in sales tax software is often the most efficient way to stay compliant. These tools offer features like:

• Real-Time Tax Calculations: Automatically apply the correct tax rate based on the customer’s location.
• Nexus Tracking: Monitor sales and transactions to identify when you exceed economic nexus thresholds.
• Automated Filings: Generate and file returns with state taxing authorities, reducing manual work.
• Rate Updates: Stay current with changing tax rates and rules across states and localities.
• International Tax Support: Handle VAT, GST, and customs duties for international sales.

Popular platforms like Avalara, TaxJar, and Vertex integrate with major e-commerce platforms, making them accessible for businesses of all sizes. For example, a small business selling on Shopify can use TaxJar to automate tax collection for all U.S. sales, while a larger retailer with international customers might choose Avalara for its robust global tax features.

Future Trends in Internet Sales Tax

The landscape of internet sales tax continues to evolve. Here are some trends to watch:

• Streamlined Sales Tax (SST): The Streamlined Sales Tax Governing Board, a coalition of states, aims to simplify sales tax compliance through standardized rules and software. As of 2025, 24 states participate in SST, and more may join.
• Increased Enforcement: States are investing in technology to track remote sellers and ensure compliance, increasing the risk of audits for non-compliant businesses.
• Global E-Commerce Growth: As online sales expand globally, businesses will face growing complexity in managing international taxes like VAT and GST.
• Automation Advancements: Advances in sales tax software and artificial intelligence will make compliance easier, even for small businesses.

Conclusion: Staying Ahead in the World of Internet Sales Tax

Navigating internet sales tax laws is a critical responsibility for online sellers, but it doesn’t have to be overwhelming. By understanding tax nexus, registering for sales tax permits, leveraging sales tax software, and staying informed about state and local regulations, businesses can manage their obligations efficiently. Whether you’re a small Etsy seller or a growing e-commerce retailer, proactive compliance ensures you avoid penalties and focus on what matters most—growing your business.

Frequently Asked Questions (FAQs)

FAQ 1: What is sales tax nexus and how does it affect online sellers?

Sales tax nexus is the connection between a business and a state that obligates the business to collect and remit sales tax in that state. For online sellers, understanding nexus is critical because it determines where and when you must comply with sales tax laws. Historically, nexus was tied to a physical presence, such as an office or warehouse, but the 2018 South Dakota v. Wayfair Supreme Court decision expanded this to include economic nexus, based on sales volume or transaction counts.

A business can establish nexus through activities like maintaining a physical location, employing workers in a state, storing inventory, or exceeding state-specific economic nexus thresholds. For example, if an online retailer in Texas sells $150,000 worth of goods to California customers, they exceed California’s $500,000 threshold and must collect sales tax there. Key points to understand about nexus include:

• Physical Nexus: Triggered by offices, warehouses, or employees in a state.
• Economic Nexus: Based on sales (e.g., $100,000 in Florida) or transactions (e.g., 200 in Illinois).
• Marketplace Nexus: Sales through platforms like Amazon may create nexus in states where the platform operates.

For instance, a small Etsy seller in Oregon shipping $20,000 to New York customers doesn’t meet New York’s $500,000 or 100-transaction threshold, so they’re exempt from collecting sales tax there. However, a larger retailer with $600,000 in sales to Florida customers must register and comply with Florida’s tax laws. To manage nexus, online sellers should track sales by state, use sales tax software to monitor thresholds, and consult state taxing authorities for specific rules.

FAQ 2: How did the South Dakota v. Wayfair decision change internet sales tax laws?

The South Dakota v. Wayfair decision in 2018 was a landmark ruling that transformed internet sales tax obligations for online sellers. Before this decision, states could only require businesses with a physical presence—like a store or warehouse—to collect sales tax, as established by the 1992 Quill Corp. v. North Dakota case. This physical presence rule allowed many online retailers to avoid collecting sales tax, creating a competitive advantage over brick-and-mortar stores and causing states to lose significant tax revenue.

The Wayfair ruling eliminated the physical presence requirement, allowing states to impose sales tax on remote sellers based on economic nexus. This means businesses with significant sales or transactions in a state, even without a physical location, must collect and remit sales tax. For example, South Dakota’s law, upheld in the ruling, requires sellers with over $100,000 in sales or 200 transactions annually to comply. Key impacts include:

• Expanded Tax Obligations: As of 2025, 45 states and the District of Columbia have economic nexus laws.
• State-Specific Thresholds: Vary widely, e.g., $500,000 in California vs. $100,000 in Florida.
• Increased Compliance Burden: Sellers must track sales across states and register for sales tax permits.

For example, a Georgia-based online clothing retailer selling $200,000 to Illinois customers must now collect sales tax in Illinois, even without a physical presence. This decision leveled the playing field but increased complexity, making sales tax software essential for compliance.

FAQ 3: Which states do not have a sales tax, and what does this mean for online sellers?

Five U.S. states—Alaska, Delaware, Montana, New Hampshire, and Oregon—do not impose a statewide sales tax, offering a unique advantage for online sellers based in these states. However, Alaska has a caveat: while there’s no state sales tax, certain localities like Anchorage and Juneau impose local sales taxes, which sellers must account for when shipping to those areas. For online sellers in these states, this means fewer tax obligations for in-state sales, but they must still consider nexus in other states where they sell.

Key considerations for sellers in these states include:

• No State Sales Tax: Sellers in Delaware or Oregon don’t collect sales tax on in-state transactions unless local taxes apply in Alaska.
• Out-of-State Sales: Sellers must monitor economic nexus thresholds in other states. For example, an Oregon-based seller with $150,000 in Florida sales must collect Florida sales tax.
• Local Taxes in Alaska: Sellers shipping to Alaskan localities must check for local tax rates.

For instance, a Montana-based online bookstore with $50,000 in sales to California customers avoids Montana sales tax but doesn’t meet California’s $500,000 threshold, so they’re exempt from California’s tax obligations. Sellers in these states should still use sales tax software to track out-of-state sales and ensure compliance with other states’ laws.

FAQ 4: What are economic nexus thresholds, and how do they vary across states?

Economic nexus thresholds define the level of sales or transactions that trigger a sales tax obligation for remote sellers in a state. Introduced after the South Dakota v. Wayfair decision, these thresholds vary by state, typically based on gross sales (e.g., taxable or retail sales) or the number of transactions. As of 2025, 45 states have implemented economic nexus laws, each with unique requirements, making it essential for online sellers to understand these variations.

Examples of state thresholds include:

• California: $500,000 in total combined sales (in-person and remote) in the current or previous year.
• Florida: $100,000 in taxable sales of tangible personal property in the previous year.
• New York: $500,000 in gross receipts and over 100 sales in the previous four sales tax quarters.
• Illinois: $100,000 in taxable sales or 200 transactions in the previous 12 months.

For example, a Texas-based online electronics store with $120,000 in Florida sales exceeds Florida’s $100,000 threshold and must collect sales tax, but their $80,000 in California sales falls below California’s threshold, so no tax is required there. Sellers must:

• Track sales and transactions by state.
• Register for sales tax permits in states where thresholds are exceeded.
• Use sales tax software to automate threshold monitoring.

These variations highlight the importance of staying informed about state-specific rules to avoid non-compliance.

FAQ 5: How can online sellers determine if they need to collect sales tax in a state?

Determining whether you need to collect sales tax in a state involves assessing whether your business has nexus—either physical or economic—in that state. This process requires reviewing your business activities, sales data, and state-specific economic nexus thresholds. Here’s how to approach it:

1. Identify Physical Nexus: Check if you have a physical presence, such as an office, warehouse, employees, or inventory in a state. For example, storing products in an Amazon FBA warehouse in Ohio creates physical nexus in Ohio.
2. Evaluate Economic Nexus: Compare your sales and transaction volumes to each state’s thresholds. For instance, if you sell $200,000 worth of goods to New York customers and have over 100 transactions, you exceed New York’s threshold.
3. Check Taxable Products: Determine if your products or services are taxable in the state. For example, clothing is exempt in Pennsylvania but taxable in Texas.
4. Consult State Resources: Visit the state’s department of revenue website for detailed nexus and taxability rules.

For example, a small online craft store in Oregon with $30,000 in California sales doesn’t meet California’s $500,000 threshold, so they don’t need to collect sales tax there. However, a larger retailer with $600,000 in Texas sales must register and collect tax in Texas. Using sales tax software can simplify this process by tracking sales and alerting you when thresholds are met.

FAQ 6: What role do marketplace facilitator laws play in internet sales tax compliance?

Marketplace facilitator laws require platforms like Amazon, eBay, Etsy, or Walmart to collect and remit sales tax on behalf of sellers using their platforms. These laws, adopted by many states post-Wayfair, shift the tax collection burden from individual sellers to the marketplace, simplifying compliance for small businesses selling through these channels. However, understanding how these laws apply is crucial for online sellers.

Key aspects of marketplace facilitator laws include:

• Tax Collection Responsibility: The marketplace collects and remits sales tax for sales made through their platform, even if the seller has nexus in the state.
• State Variations: Most states with sales tax have these laws, but rules vary. For example, California requires marketplaces to collect tax for all taxable sales, while some states exempt certain products.
• Non-Marketplace Sales: Sellers must still collect tax for sales made through their own websites or other channels.

For example, a seller on Etsy shipping $50,000 worth of handmade goods to Florida customers doesn’t need to collect sales tax for those transactions, as Etsy handles it under Florida’s marketplace facilitator law. However, if they sell $150,000 through their own website to Florida customers, they must collect tax themselves. Sellers should:

• Verify which platforms handle tax collection.
• Track non-marketplace sales for nexus obligations.
• Use sales tax software to manage mixed sales channels.

FAQ 7: Why is sales tax software essential for online sellers?

The complexity of internet sales tax—with varying state thresholds, local tax rates, and filing requirements—makes manual compliance nearly impossible for most online sellers. Sales tax software like Avalara, TaxJar, or Vertex automates critical tasks, reducing errors and saving time. These tools are essential for businesses selling across multiple states or internationally.

Benefits of sales tax software include:

• Real-Time Tax Calculations: Automatically apply the correct tax rate based on the customer’s location. For example, a sale to New York City includes the combined 8.875% state and local rate.
• Nexus Tracking: Monitor sales and transactions to identify when economic nexus thresholds are exceeded.
• Automated Filings: Generate and submit tax returns to state authorities, ensuring timely compliance.
• Rate Updates: Stay current with changing tax rates and exemptions across states and localities.
• International Support: Calculate VAT, GST, or customs duties for global sales.

For instance, a Shopify-based retailer selling to customers in 10 states can use TaxJar to calculate taxes, track nexus, and file returns automatically. Without software, they’d need to manually research rates and deadlines, risking errors. Small businesses with limited resources particularly benefit from automation, ensuring compliance without overwhelming administrative burdens.

FAQ 8: How do sales tax holidays affect online sellers?

Sales tax holidays are temporary periods during which certain products, like school supplies, clothing, or electronics, are exempt from sales tax in specific states. These events, often held before the school year or during major shopping seasons, can affect how online sellers calculate and collect taxes. Understanding these holidays is crucial to avoid over- or under-charging customers.

Key points about sales tax holidays include:

• State-Specific Rules: Each state sets its own eligible products, price limits, and dates. For example, Florida’s back-to-school holiday exempts clothing under $100 and school supplies under $50.
• Online Applicability: Online sales are typically included, provided the order is placed during the holiday period.
• Customer Expectations: Shoppers may expect tax exemptions, so clear communication at checkout is essential.

For example, during Texas’s August sales tax holiday, an online retailer selling laptops under $3,000 must ensure no sales tax is charged on eligible items shipped to Texas customers. Sellers should:

• Check state taxing authority websites for holiday schedules and rules.
• Update e-commerce platforms to reflect exemptions during these periods.
• Use sales tax software to automate holiday-specific tax calculations.

Failure to apply exemptions can lead to customer dissatisfaction, while incorrect tax collection can result in compliance issues.

FAQ 9: What are the challenges of managing international sales tax for online businesses?

Selling internationally introduces additional complexity beyond U.S. sales tax, as online businesses must navigate taxes like Value-Added Tax (VAT) in Europe, Goods and Services Tax (GST) in countries like Canada or Australia, and customs duties. These taxes vary by country, product type, and sales volume, making compliance a significant challenge for e-commerce businesses.

Key challenges include:

• Diverse Tax Systems: Each country has unique tax rates and rules. For example, the EU’s VAT rates range from 17% to 27%, depending on the member state.
• Thresholds for Registration: Many countries require businesses to register for VAT/GST once sales exceed a threshold, e.g., £85,000 in the UK.
• Customs and Duties: Importing goods may incur additional fees, which sellers must calculate and communicate to customers.
• Currency and Reporting: Taxes must be reported in the local currency, and filings may have different schedules than U.S. taxes.

For instance, a U.S.-based software company selling $100,000 in digital products to UK customers must register for VAT in the UK, charge the appropriate rate (e.g., 20%), and file returns. Sales tax software with international capabilities can:

• Calculate VAT/GST based on customer location.
• Track international sales thresholds.
• Generate compliant reports for foreign tax authorities.

Businesses should also consult international tax experts to ensure compliance with global regulations.

FAQ 10: How can online sellers prepare for a sales tax audit?

A sales tax audit is a state-led review of a business’s tax records to ensure compliance with sales tax laws. Audits can be triggered by high sales volumes, discrepancies in filings, or random selection. Preparing for an audit is essential to avoid penalties, interest, or reputational damage. Online sellers should take proactive steps to maintain accurate records and streamline the audit process.

Steps to prepare for a sales tax audit include:

• Maintain Detailed Records: Keep records of sales, tax collected, exemptions applied, and returns filed for at least 3–7 years, depending on state requirements.
• Use Sales Tax Software: Tools like Avalara or TaxJar provide audit-ready reports, tracking sales by state and locality.
• Document Nexus: Record activities that create physical or economic nexus, such as warehouse locations or sales thresholds.
• Verify Exemptions: Ensure exemptions for products (e.g., clothing in New Jersey) or customers (e.g., nonprofits) are properly documented.
• Conduct Internal Reviews: Regularly audit your own records to identify and correct errors before a state audit.

For example, a California-based online retailer audited by Texas should provide detailed sales reports showing $200,000 in taxable sales, tax collected, and proof of timely filings. If discrepancies are found, such as under-collected taxes, the retailer could face penalties. Consulting a tax professional and using sales tax software can ensure records are accurate and accessible, making audits less stressful and more manageable.
