Texas Sales Tax Nexus Rules for E-Commerce Sellers (2026)

Texas sales tax nexus guide

TL;DR: Texas requires sales tax registration once your annual sales to Texas customers reach $500,000—one of the highest thresholds in the nation. The threshold uses OR logic (revenue alone triggers nexus), applies to a rolling 12-month period, and includes marketplace sales regardless of who collects the tax.

What Is Economic Nexus in Texas?

Economic nexus is the legal connection between your e-commerce business and Texas based purely on your sales activity—not on whether you have an office, warehouse, or employee in the state. Before 2018, remote sellers could largely operate in other states without collecting Texas sales tax. That changed after the U.S. Supreme Court's South Dakota v. Wayfair decision, which authorized states to require tax collection from remote sellers meeting specific thresholds.

Texas responded by establishing economic nexus rules designed to ensure online retailers pay their fair share of state revenue. Once your sales activity crosses Texas's threshold, you're obligated to register, collect, and remit sales tax—even if you've never visited Texas or have customers there you've never met.

For many e-commerce sellers, this requirement arrives unexpectedly. You might have been happily selling to Texas customers for years without realizing you've triggered a nexus obligation. Understanding Texas's specific rules helps you stay compliant, avoid back tax liability, and protect your business from penalties.

Texas's Nexus Thresholds (2026)

Texas uses a straightforward revenue-based approach to economic nexus. The state has no transaction threshold—only revenue matters.

The $500,000 Annual Revenue Threshold

If your gross revenues from sales to Texas customers reach $500,000 or more in a rolling 12-month period, you've established economic nexus in Texas. This threshold ranks among the highest in the nation—many states set thresholds at $100,000, meaning Texas gives you significantly more runway before registration is required.

What Counts as Revenue?

Texas counts all gross revenue from sales to Texas customers, including:

Sales of taxable products
Sales of tax-exempt items (groceries, certain services, etc.)
Shipping charges (if taxable in Texas)
Marketplace sales through Amazon, Etsy, and other platforms
International sales (if delivered to a Texas address)

This is a critical detail. Many sellers mistakenly believe only "taxable sales" count toward the threshold. That's incorrect. Texas includes every dollar of revenue, regardless of whether sales tax applies to that specific item.

Example: If you sold $350,000 of clothing, $100,000 of books (often exempt), and $50,000 of taxable services to Texas customers, your total nexus revenue is $500,000—you've hit the threshold.

No Transaction Threshold

Unlike some states, Texas doesn't require you to track transaction counts. You could have 10,000 transactions or 100 transactions—what matters is the dollar amount. If your revenue exceeds $500,000, you must register, regardless of how many individual orders that represents.

How Texas Calculates Nexus

Accurate nexus calculations require understanding exactly how Texas measures your threshold.

The Rolling 12-Month Period

Texas doesn't use a calendar year. Instead, it uses a rolling 12-month measurement period, which means:

At any given moment, Texas looks back at your prior 12 consecutive months of sales
If you're checking your nexus status in June 2026, you'd count all sales from June 2025 through May 2026
If you're checking in November 2026, you'd count sales from November 2025 through October 2026
This rolling calculation happens continuously, not just on January 1st each year

Starting and Maintaining Nexus

Once you establish nexus by exceeding $500,000 in a rolling 12-month period, you remain obligated to collect and remit sales tax going forward. Your nexus status doesn't automatically reset on December 31st.

You can potentially stop collecting tax only if you demonstrate a full 12-month period where your sales fell below $500,000. Even then, you should contact the Texas Comptroller before ceasing collection to confirm you're no longer required.

How to Calculate Your Current Threshold Status

To determine if you've hit economic nexus in Texas:

Identify your measurement period — Use the past 12 consecutive months (or current calendar year if you prefer initial tracking)
Gather all Texas sales data — Export sales records from your e-commerce platform, marketplace accounts, and any other channels
Include all revenue sources — Website sales, Amazon, Etsy, eBay, marketplace sales, and any other channels selling to Texas addresses
Sum the total — Add all gross revenue (don't subtract refunds, just count what was sold)
Compare to $500,000 — If your total exceeds this amount, you've triggered economic nexus

Most e-commerce sellers use accounting software (QuickBooks, Xero, FreshBooks) or platform dashboards to generate sales reports by state. If your platform lacks this functionality, consider implementing a dedicated tax compliance tool.

Do Marketplace Sales Count in Texas?

This question directly affects thousands of sellers on Amazon, Etsy, Walmart Marketplace, and other platforms.

Marketplace Sales Are Included in Your Nexus Calculation

Yes, absolutely. Every dollar you generate through marketplace platforms counts toward your $500,000 threshold in Texas. If you sold $300,000 through your own website and $250,000 through Amazon to Texas customers, your total is $550,000—you've exceeded the threshold and must register.

Who Collects the Sales Tax?

Here's where the situation becomes nuanced:

Large Marketplace Facilitators — Platforms like Amazon, Etsy, Walmart Marketplace, and others are registered as marketplace facilitators with Texas. They collect and remit sales tax on your behalf for sales made through their platforms
Your Responsibility — Even though the marketplace handles tax collection for your platform sales, those sales still count toward your nexus threshold
Your Direct Sales — If you also operate your own e-commerce website or sell through channels where you handle tax collection, you're responsible for collecting and remitting on those direct sales once you hit the threshold

The Bottom Line

You cannot exclude marketplace sales from your nexus calculation, even if the marketplace itself handles tax collection. Your nexus obligation is based on total sales volume. The tax collection responsibility is a separate matter handled by the marketplace facilitator.

Example: You sell $300,000 through Amazon (Amazon collects tax for you) and $250,000 through your Shopify store (you collect tax). Your total nexus revenue is $550,000. Amazon handles tax on their sales; you handle tax on your direct sales. But you had to register because your combined sales exceeded the threshold.

What Happens When You Exceed the Threshold

Crossing the $500,000 threshold triggers immediate obligations and legal responsibilities.

Registration Is Required

Once your rolling 12-month sales to Texas reach $500,000, you must register with the Texas Comptroller of Public Accounts. Ideally, you should register as soon as you realize you've crossed the threshold—not weeks or months later.

Delayed registration doesn't eliminate your tax obligations. Texas may assess taxes on sales made before registration, along with interest and potential penalties for late registration.

Tax Collection Obligations Begin

After registering, you must:

Collect sales tax on all taxable sales to Texas customers
Calculate correct rates based on the customer's delivery address (Texas has a statewide rate plus local district taxes that vary by location)
Maintain detailed records of all sales, taxes collected, and documentation supporting your calculations
File returns on the schedule assigned by the Texas Comptroller

Filing and Remittance Schedule

Your filing frequency depends on your sales volume:

High-volume sellers typically file monthly
Mid-volume sellers often file quarterly
Lower-volume sellers might file annually

The Texas Comptroller determines your filing schedule upon registration. You'll receive instructions specifying your due dates and filing method (typically online through their portal).

Penalty Exposure for Non-Compliance

Failing to register or collect tax once you've exceeded the threshold can result in:

Back tax assessments covering unpaid tax from when you should have been collecting
Interest charges accruing on unpaid taxes at rates set by Texas law
Compliance penalties for failure to register or file
Account restrictions that may complicate future business operations
Audit risk if the Texas Comptroller identifies your non-compliance

Best Practices for Threshold Compliance

When you're approaching $400,000 in Texas sales, start preparing:

Have your business registration documents and tax ID information ready
Ensure your e-commerce platform is configured to calculate Texas sales tax correctly
Identify all sales channels (website, marketplaces, social commerce) to ensure complete data integration
Consider consulting with a tax professional to review your nexus status and preparation plan

Proactive preparation prevents last-minute scrambling and helps you register smoothly upon crossing the threshold.

How to Register for Sales Tax in Texas

The Texas registration process is relatively straightforward and can often be completed in less than an hour.

Step 1: Gather Required Information

Before starting, have the following items ready:

Your business legal name and any trade names
Business entity type (sole proprietorship, LLC, corporation, S-corporation, partnership, etc.)
Business physical address and mailing address (can be the same)
Federal Employer Identification Number (EIN) or Social Security Number if you're a sole proprietor
Detailed description of your business activities and product types
Ownership structure information (names and ownership percentages of owners)
Estimated monthly sales volume for tax purposes
Bank account information for potential future remittance setup

Step 2: Access the Texas Registration Portal

Visit the official Texas Comptroller registration website at https://comptroller.texas.gov/taxes/permit/. The portal provides online registration for sales tax permits. You can complete the entire application online without visiting an office.

Step 3: Complete the Online Application

Follow the step-by-step prompts to enter your business information. The system is designed to be seller-friendly and typically takes 20–40 minutes to complete. The application asks standard business questions and will verify information provided.

Step 4: Submit Your Application

Once you've completed all required fields, submit your application electronically. Texas does not charge a registration fee for sales tax permits.

Step 5: Receive Your Sales Tax Permit

After submission, the Texas Comptroller typically processes applications quickly, often within 1–3 business days. You'll receive:

Your Texas Sales Tax Permit Number (you'll need this for filing and other tax purposes)
A Certificate of Sales Tax Permit suitable for your records
Filing instructions and information about your assigned filing frequency
Details about your due dates for tax returns
Access to the online filing portal where you'll submit future returns

Step 6: Configure Your Business Systems

Once registered, immediately:

Set up sales tax calculation on your e-commerce platform to charge the appropriate Texas rates based on customer location
Configure marketplace integrations if you sell through multiple channels to ensure comprehensive tax tracking
Implement record-keeping systems to document all sales and tax collected
Set calendar reminders for your return filing deadlines

Step 7: Begin Filing Returns

File your first return according to the schedule provided by the Texas Comptroller. Include all sales made from your registration date forward, plus any historical sales if the Comptroller requests them.

How NexusMonitor Helps Track Your Texas Nexus

Managing economic nexus thresholds across multiple states becomes increasingly complex as your e-commerce business scales. Specialized monitoring tools eliminate manual calculations and provide real-time insights into your nexus status.

Real-Time Sales Tracking and Threshold Monitoring

NexusMonitor continuously aggregates sales data from all your channels—your website, Amazon, Etsy, eBay, Shopify, WooCommerce, and custom integrations—providing a unified dashboard showing your current nexus status in Texas and every other sales tax state. You always know exactly where you stand against the $500,000 threshold without manually exporting and recalculating spreadsheets monthly.

The platform tracks your rolling 12-month revenue automatically, accounting for the complex calendar calculations Texas requires. As your sales fluctuate, the system updates your threshold position in real time, eliminating surprises.

Automated Threshold Alerts and Early Notification

When you're approaching $400,000 in Texas sales, NexusMonitor sends automated alerts so you can prepare for registration before you actually exceed the threshold. Many sellers use this advance notice to organize their documentation, configure their tax systems, and coordinate with tax professionals.

Once you cross $500,000, the system immediately notifies you, confirming your nexus establishment and prompting next steps. This early warning prevents accidental delays in registration that could trigger penalties.

Multi-State Nexus Management

If you sell nationally, you likely have nexus in multiple states with different thresholds, logic types, and measurement periods. NexusMonitor simultaneously tracks your status in all 50 states and territories, organizing thresholds by state and highlighting which ones you've exceeded.

Many sellers in Texas also have nexus obligations in neighboring states like Arkansas, Louisiana, and Oklahoma. A comprehensive monitoring system keeps all these thresholds organized and current, preventing confusion and compliance gaps.

Detailed Reporting and Documentation

NexusMonitor generates detailed reports showing your sales by state, your current threshold position, and the precise calculations supporting your nexus status. These reports are invaluable for:

Audit preparation — If the Texas Comptroller questions your nexus status or tax calculations, you have documented proof
Accountant coordination — Share reports with your tax professional to verify compliance
Historical records — Maintain documentation showing when you established nexus and all sales leading to that determination

The platform also tracks tax collected versus tax owed, identifying any gaps in your collection process and helping ensure you remit accurate amounts to Texas.

Seamless Integration with Your Sales Channels

Rather than manually exporting data from each sales channel, NexusMonitor integrates directly with Shopify, WooCommerce, Amazon, Etsy, BigCommerce, and dozens of other platforms. The system automatically pulls transaction data, customer location information, and sales amounts, eliminating manual data entry and the errors it causes.

Whether you sell through one channel or twenty, NexusMonitor consolidates all sales into a single unified view showing your Texas nexus status across your entire business.

Frequently Asked Questions

What is the sales tax rate in Texas?

Texas has a statewide sales tax rate of 6.25%, but the effective rate in most localities is higher due to local district taxes. Local rates typically range from 7.25% to 8.25% depending on the customer's specific address within Texas. When you register with the Texas Comptroller, they'll provide guidance on calculating the correct rate for each delivery address.

Does Texas use AND or OR logic for nexus thresholds?

Texas uses OR logic. This means that exceeding the revenue threshold alone triggers economic nexus—you don't need to meet multiple criteria simultaneously. Since Texas has no transaction threshold, revenue is the sole determination factor. Once you hit $500,000 in sales to Texas, you must register.

When do I need to start collecting sales tax in Texas?

You must start collecting sales tax immediately upon exceeding the $500,000 threshold. Ideally, you should register with the Texas Comptroller as soon as you recognize you've crossed this amount. Texas may assess tax obligations on sales made before registration, so delayed registration doesn't eliminate your liability—it only increases your exposure to penalties.

Do Amazon and marketplace sales count toward my Texas nexus?

Yes, completely. Every dollar you generate through Amazon, Etsy, Walmart Marketplace, and other third-party platforms counts toward your $500,000 threshold in Texas. Even though marketplace facilitators collect and remit tax on your behalf for those platform sales, the sales amount itself triggers your nexus obligation. You cannot exclude marketplace sales from your nexus calculation.

Can I deregister if my sales drop below the threshold?

Potentially, yes, but with conditions. If your sales fall below $500,000 in a rolling 12-month period after you've registered, you may be eligible to stop collecting tax. However, you should contact the Texas Comptroller to formally request deregistration rather than simply ceasing collection. The state may still expect you to file final returns and settle any outstanding tax liability. Consult a tax professional before taking action to stop collecting.

What happens if I don't register after exceeding the threshold?

Failing to register can result in significant consequences: the Texas Comptroller may assess back taxes covering your obligations from when you should have registered, add interest charges on those assessments, impose penalties for non-compliance, and conduct audits of your sales records. Early registration is always the better choice.

Does Texas require registration if I only sell tax-exempt items?

No. If all your sales to Texas are tax-exempt items (such as groceries or certain services), you wouldn't be required to collect tax. However, for nexus threshold purposes, Texas counts all gross revenue, including exempt items. So if you sold $500,000 of tax-exempt products, you've still exceeded the threshold and must register—you'd simply collect zero tax on those specific sales while collecting on any taxable items you do sell.

How do I know the correct tax rate for my Texas customers?

Texas uses a statewide rate of 6.25% plus local district rates that vary by location. When you register, the Texas Comptroller will provide access to a tax rate lookup tool that shows the exact applicable rate for any Texas address. Most e-commerce platforms integrate this lookup, automatically calculating the correct rate based on the customer's delivery address during checkout.
