Texas Sales Tax Nexus for Shopify Sellers: The $500,000 Rule and What Comes With It

Texas has one of the higher and, on paper, simpler economic nexus thresholds in the country. No transaction count to track, no dual test, just one number: $500,000. But simple doesn't mean straightforward, and there are a few details in Texas's rule that catch Shopify sellers off guard.

Here's what actually matters if you sell to Texas customers.

The Threshold Itself

Texas requires remote sellers to register and collect sales tax once their total Texas revenue in the preceding 12 calendar months reaches $500,000. This has been the rule since October 1, 2019. Unlike states such as Georgia or Hawaii, Texas has no separate transaction-count trigger. Revenue is the only thing that matters.

That $500,000 figure counts everything, not just taxable sales. Texas includes both taxable and non-taxable sales of tangible personal property and services when calculating whether you've crossed the line. A store with a lot of exempt or wholesale Texas transactions can't assume those sales don't count toward the threshold.

Below $500,000? You're in a Genuine Safe Harbor

Texas describes this clearly as a safe harbor. Remote sellers with total Texas revenue under $500,000 are not required to obtain a permit or collect, report, and remit tax, full stop. There's no partial obligation below the threshold, no smaller registration tier. You're either under the line or you're not.

Marketplace Sales Count Toward Your Threshold Here

This is the detail that surprises the most sellers, especially anyone coming from a state like Georgia or Illinois where marketplace sales are typically excluded from an individual seller's own threshold.

Since April 2020, Combined Sales Are What Counts

In Texas, marketplace-facilitated sales, think Amazon or Etsy orders, still count toward your $500,000 figure, even though the marketplace itself is the one actually collecting and remitting the tax on those transactions. This has been the rule since an April 1, 2020 update to Texas's guidance, which requires remote sellers to combine sales made through all channels when calculating whether they've exceeded the threshold.

If you sell $200,000 through your own Shopify store and $350,000 through Amazon into Texas, you've crossed the threshold overall, even though your direct Shopify revenue alone wouldn't have gotten you there.

What This Means in Practice

The practical result: you'd need to register and start collecting on your direct Shopify sales, even though Amazon is already handling its share. Sellers running a multi-channel operation should track combined Texas revenue across every platform, not just their own website.

Registration Timing

Texas gives you a bit of runway once you cross the threshold. Per the Comptroller's own guidance, registration and collection must begin no later than the first day of the fourth month after the month you exceeded $500,000. Cross the threshold in March, and you'd need to be registered and collecting by July 1. That's more breathing room than most states allow, but it's still a real deadline, not an open-ended one.

Rates and What Registration Looks Like

Texas charges a 6.25% state sales tax rate, with local jurisdictions able to add up to 2% more, for a maximum combined rate of 8.25%. Registration happens through the Comptroller's eSystems portal, and once registered, you'll be assigned a filing frequency, monthly, quarterly, or annually, based on your expected tax volume.

Don't Confuse This With Texas Franchise Tax

This is worth its own section because it genuinely trips people up. Texas sales tax nexus and Texas franchise tax nexus are two entirely different taxes with two different purposes, and crossing the threshold for one doesn't automatically mean the same thing for the other.

Two Separate Thresholds, Two Separate Filings

Franchise tax is a privilege tax on doing business in Texas, based on a margin calculation, not a consumer-facing sales tax. It has its own nexus rules, generally tied to $500,000 or more in annual gross receipts from Texas business, and its own no-tax-due threshold, currently $2,470,000 for the 2026-2027 report years, below which entities don't owe the tax even though they may still need to file.

Obtaining a Texas sales tax permit can itself trigger franchise tax nexus, so it's worth understanding both obligations exist separately before you register for either one. A CPA familiar with Texas specifically, not just general multi-state sales tax, is the right person to sort this out for your situation.

Texas Isn't Just a Sales Tax State to Watch

Worth knowing if you sell meaningfully into Texas: the state also has a comprehensive privacy law, the Texas Data Privacy and Security Act, effective since July 1, 2024. Unlike most state privacy laws, TDPSA has no minimum revenue threshold, which means even smaller Shopify stores selling into Texas can fall under its scope depending on consumer data volume. That's a separate compliance question from sales tax, but it's one more reason Texas deserves its own careful look rather than treating it as just another line on a spreadsheet.
