Quick Answer
When do online sellers need to collect Texas sales tax? Following the 2018 Wayfair decision, Texas requires tax collection based on economic activity, not just physical presence. Key facts:
- Economic nexus is triggered at $500,000 in Texas revenue over the preceding 12 months
- Marketplace facilitators(Amazon, Etsy, Walmart Marketplace) generally collect and remit tax on behalf of third-party sellers
- Sellers using marketplaces exclusively may have reduced direct collection obligations, but reporting requirements may still apply
- Drop shipping arrangements raise distinct nexus and resale certificate questions even without physical inventory in Texas
- Out-of-state sellers below the economic nexus threshold and without another Texas nexus connection generally have no collection obligation
Key Takeaways
- Since the 2018 South Dakota v. Wayfair decision, states including Texas may require out-of-state sellers to collect sales tax based on economic activity, not just physical presence.
- Texas's economic nexus threshold is $500,000 in Texas revenue over the preceding 12 months — there is no separate transaction-count threshold under current Texas law.
- Marketplace facilitators are generally required to collect and remit Texas sales tax on behalf of third-party sellers using their platform, which may relieve individual sellers of direct collection duties for those sales.
- Sellers using multiple channels (their own website plus marketplaces) need to evaluate nexus and collection obligations separately for each channel.
- Drop shipping arrangements can create complex nexus and resale certificate questions, particularly when the seller, supplier, and customer are in different states.
- Even sellers who rely on marketplace facilitator collection may have residual filing or reporting obligations depending on their overall Texas activity.
- Out-of-state sellers below the economic nexus threshold and without another Texas physical presence connection generally have no Texas sales tax collection obligation.
- Sales tax sourcing rules determine which local tax rate applies to a given transaction, adding complexity for multi-jurisdiction shipping.
The rise of e-commerce has transformed sales tax compliance from a largely physical-presence question into a complex, multi-jurisdictional analysis. For Texas-based and out-of-state online sellers alike, understanding economic nexus thresholds, marketplace facilitator rules, and the specific complications of drop shipping is essential to avoiding both under-collection liability and unnecessary over-collection.

1. Background: The Wayfair Decision and Economic Nexus
For decades, states could only require a business to collect sales tax if the business had a physical presence in the state. The U.S. Supreme Court's 2018 decision in South Dakota v. Wayfair, Inc., 138 S. Ct. 2080 (2018), overturned this physical-presence requirement, allowing states to impose collection obligations based on a seller's economic activity within the state — even without any physical presence.
Texas, like most states, subsequently enacted economic nexus rules following the Wayfair decision. This means an online seller with no employees, offices, or inventory in Texas may still be required to collect Texas sales tax if its sales into Texas exceed the applicable threshold.
The Wayfair decision fundamentally changed sales tax compliance for e-commerce — physical presence is no longer required for a state to impose a sales tax collection obligation on a remote seller.
2. Texas Economic Nexus Threshold
A remote seller without any physical presence in Texas generally becomes obligated to collect Texas sales tax once its Texas revenue exceeds $500,000 in the preceding 12 months.
3. Physical Presence Nexus
Economic nexus did not replace physical presence nexus—it supplemented it. A business may still establish Texas sales tax nexus through traditional physical presence factors regardless of its revenue level.
| Physical Presence Factor | Nexus-Creating? |
|---|---|
| Office or retail location in Texas | Yes |
| Employees or independent sales representatives in Texas | Yes |
| Inventory stored in Texas (including third-party fulfillment warehouses) | Yes — including inventory stored in Texas through a fulfillment service |
| Owned or leased property in Texas | Yes |
| Affiliate or related entity conducting business in Texas | Potentially — subject to affiliate nexus analysis |
Risk
Sellers using third-party fulfillment services (such as Fulfillment by Amazon) may have inventory stored in Texas warehouses without realizing it, which can create physical presence nexus regardless of the seller's revenue level. Reviewing fulfillment service inventory location reports is commonly recommended for sellers using such programs.
Physical presence nexus remains relevant even after Wayfair — inventory stored in Texas fulfillment centers can create a collection obligation regardless of the seller's revenue threshold status.
4. Marketplace Facilitator Rules
Texas, like most states, has enacted marketplace facilitator laws that shift the sales tax collection responsibility from individual third-party sellers to the marketplace platform itself for sales made through that platform.
How Marketplace Facilitator Rules Work
- A marketplace facilitator (e.g., Amazon, Etsy, Walmart Marketplace, eBay) that meets Texas's nexus requirements is generally required to collect and remit Texas sales tax on all sales made through its platform — including sales by third-party sellers
- This obligation generally applies regardless of whether the individual third-party seller independently has Texas nexus
- Texas marketplace facilitator rules generally place the obligation to collect, remit, and account for tax on qualifying marketplace facilitators for sales made through their platforms, though sellers can retain separate reporting obligations depending on their overall activity
Marketplace facilitators generally bear the Texas sales tax collection obligation for sales made through their platforms — sellers should confirm this arrangement for each marketplace they use rather than assuming uniform treatment, and should also be aware that marketplace fees themselves may now carry their own tax treatment.
Multi-Channel Sellers: Marketplace Plus Direct Sales
Many e-commerce businesses sell through multiple channels — a marketplace platform, an independent website, and sometimes a physical retail presence. Each channel may require separate nexus and collection analysis.
| Sales Channel | Who Generally Collects Texas Tax |
|---|---|
| Sales through a marketplace facilitator | The marketplace facilitator (generally) |
| Direct sales through the seller's own website | The seller (if the seller has nexus, whether physical or economic) |
| Sales through a physical Texas retail location | The seller (physical presence nexus) |
Multi-channel sellers should evaluate nexus and collection obligations separately for each sales channel rather than assuming that marketplace facilitator collection covers all Texas sales tax obligations.
6. Obligations for Out-of-State Sellers Shipping to Texas
An out-of-state seller shipping products to Texas customers must evaluate its Texas nexus status to determine collection obligations.
Out-of-state sellers without physical presence and below the $500,000 Texas revenue threshold generally have no Texas sales tax collection obligation for direct sales — but should continue monitoring revenue against the threshold as sales grow.
7. Drop Shipping Considerations
Drop shipping arrangements — where a seller takes orders but a third-party supplier ships directly to the customer, with inventory never passing through the seller's own hands — raise distinct sales tax questions.
Key Drop Shipping Scenarios
Risk
Drop shippers who do not provide valid resale certificates to their suppliers may be charged sales tax on the wholesale purchase price by the supplier — tax that is generally not recoverable even though the drop shipper also separately collects tax from the end customer, potentially resulting in tax being effectively collected twice within the supply chain.
Drop shipping arrangements require analyzing nexus separately for both the seller and the supplier, and maintaining valid resale certificates between them is important to avoid double taxation within the supply chain.
8. Sales Tax Sourcing Rules
Once a collection obligation is established, the seller must determine which local tax rate applies. Texas sales tax sourcing rules determine whether the seller's location or the customer's location controls the applicable local rate — the correct method depends on the type of seller and transaction. In general, Texas uses origin-based sourcing for sales made from a Texas business location and destination-based sourcing for remote sellers shipping into Texas from outside the state.
Determining the correct combined tax rate requires applying Texas's specific sourcing rules, which can differ based on whether the seller has a Texas location and the nature of the transaction — qualifying remote sellers can simplify this by electing the single local use tax rate.
9. Registration and Filing for Online Sellers
Online sellers who establish Texas nexus must register for a Texas Sales and Use Tax Permit, generally available through the Comptroller's online registration system using the business's EIN. Filing frequency (monthly, quarterly, or annual) is generally assigned based on collection volume, with returns due by the 20th of the month following the filing period, unless a different filing deadline applies under Comptroller rules for a specific situation.
Businesses that determine they have Texas sales tax nexus generally must register for a Texas Sales and Use Tax Permit before collecting and remitting tax — sellers should not wait until a Comptroller notice arrives, as registering proactively before collection obligations begin is the standard compliance approach.
10. Exemption Certificates in E-Commerce
E-commerce sellers commonly encounter several types of exemption documentation:
- Resale certificates from drop shipping customers or wholesale buyers who will resell the product
- Exemption certificates from exempt organizations purchasing for exempt purposes
- Direct pay permits from certain large purchasers who self-assess and remit their own use tax
Risk
E-commerce platforms processing high volumes of transactions sometimes lack robust systems for collecting and verifying exemption certificates at the point of sale, creating documentation gaps that surface during audits. Implementing a systematic exemption certificate collection process — ideally integrated into the checkout or account-setup flow for B2B customers — is commonly recommended.
High-volume e-commerce operations benefit from systematic exemption certificate collection processes integrated into the sales platform, rather than ad hoc collection after the fact.
11. Sales Tax Automation Software
Given the complexity of multi-jurisdiction sales tax compliance — economic nexus thresholds across many states, marketplace facilitator rules, sourcing rules, and exemption certificate management — many e-commerce businesses use third-party sales tax automation software to manage compliance.
Sales tax automation tools may meaningfully reduce compliance burden for multi-state e-commerce sellers, particularly those approaching or exceeding economic nexus thresholds in several states simultaneously.
12. Common Mistakes E-Commerce and Online Sellers Make
Common Mistake Not Monitoring Texas Revenue Against the Economic Nexus Threshold
Growing online sellers sometimes fail to track Texas-specific revenue on a rolling basis, missing the point at which they cross the $500,000 economic nexus threshold and should have begun collecting tax.
Common Mistake Assuming Marketplace Facilitator Collection Eliminates All Texas Tax Obligations
Sellers who rely entirely on marketplace facilitator collection sometimes overlook other potential Texas tax obligations — including franchise tax — that may still apply to their overall business activity.
Common Mistake Overlooking Fulfillment Service Inventory as a Source of Physical Nexus
Sellers using third-party fulfillment services may have inventory stored in Texas warehouses without realizing it, creating physical presence nexus and a collection obligation independent of the economic nexus threshold.
Common Mistake Not Obtaining Resale Certificates in Drop Shipping Arrangements
Drop shippers who fail to provide valid resale certificates to their suppliers may be charged tax on wholesale purchases that is generally not recoverable, while also separately collecting tax from the end customer — resulting in inefficient or duplicative tax cost.
Common Mistake Applying a Single Flat Tax Rate Across All Texas Sales
Texas has many local jurisdictions with varying combined rates up to 8.25%. Applying a single statewide rate rather than the correct sourced rate for each transaction may result in under- or over-collection.
Common Mistake Failing to Reconcile Marketplace-Collected vs. Self-Collected Sales
Multi-channel sellers who do not clearly separate marketplace-facilitated sales (where the platform collects tax) from direct sales (where the seller collects tax) may misreport on their own sales tax returns, leading to either double-reporting or gaps in reporting.
Common Mistake Not Reassessing Nexus When Business Models Change
A seller that adds a new fulfillment center, begins selling on a new marketplace, or significantly grows in a new state should reassess nexus determinations rather than relying on a one-time analysis performed years earlier.
13. E-Commerce Sales Tax Compliance Checklist
☐ Tracked Texas revenue on a rolling 12-month basis to monitor the $500,000 economic nexus threshold
☐ Reviewed fulfillment service inventory location reports to identify any Texas-based physical presence nexus
☐ Confirmed whether each marketplace platform used (Amazon, Etsy, Walmart Marketplace, etc.) is collecting and remitting Texas tax as a marketplace facilitator
☐ Separately evaluated nexus and collection obligations for direct website sales versus marketplace sales
☐ Registered for a Texas Sales and Use Tax Permit if nexus is established for direct sales
☐ Implemented sourcing-rule-compliant rate calculation for Texas transactions (rather than a single flat rate)
☐ For drop shipping arrangements: confirmed nexus status of both the seller and supplier, and obtained valid resale certificates where applicable
☐ Established a systematic exemption/resale certificate collection process integrated into the sales platform
☐ Evaluated whether sales tax automation software would meaningfully reduce compliance burden given the business's multi-state footprint
☐ Reconciled marketplace-collected sales against self-collected sales when preparing Texas sales tax returns
☐ Confirmed assigned filing frequency and calendared the 20th-of-month filing deadlines
☐ Established a process to reassess nexus when adding new fulfillment centers, marketplaces, or significant growth in new states

15. Frequently Asked Questions
Do Shopify sellers need to collect Texas sales tax?
Generally, yes — unlike Amazon or Etsy, Shopify itself typically does not function as a marketplace facilitator collecting tax on the seller's behalf; it is primarily a platform for operating an independent online store. Sellers using Shopify (or a similar direct-to-consumer platform) should evaluate their own Texas sales tax obligations based on their nexus status and sales activity, rather than assuming the platform is handling collection for them.
Does Amazon automatically collect Texas sales tax?
Amazon Marketplace generally collects and remits Texas sales tax on qualifying marketplace transactions under Texas's marketplace facilitator rules. However, sellers should separately evaluate whether they have other Texas obligations — such as franchise tax, physical presence nexus from fulfillment center inventory, or sales through non-Amazon channels — that Amazon's collection does not address.
Do small online businesses need a Texas sales tax permit?
A business generally needs a Texas Sales and Use Tax Permit once it is required to collect Texas sales tax, which may occur through physical presence nexus (regardless of size) or by crossing the $500,000 economic nexus threshold. A small business with modest sales may have no Texas registration obligation yet, but should monitor its revenue and any physical presence factors as it grows.
When does an out-of-state seller need to collect Texas sales tax?
An out-of-state seller generally must collect Texas sales tax if it has physical presence nexus (employees, inventory, or property in Texas) or if its Texas revenue exceeds the economic nexus threshold of $500,000 over the preceding 12 months. Sellers below this threshold and without another Texas nexus connection generally have no Texas collection obligation, though they should continue monitoring revenue as sales grow.
What is the Texas economic nexus threshold?
The Texas economic nexus threshold is $500,000 in Texas revenue over the preceding 12 calendar months. Unlike some states, Texas's current standard does not include a separate transaction-count threshold — it is based solely on revenue. Always verify the current threshold with the Texas Comptroller, as thresholds can change through legislation.
Do I need to collect Texas sales tax if I sell exclusively through Amazon or Etsy?
Generally, marketplace facilitators like Amazon and Etsy are required to collect and remit Texas sales tax on behalf of third-party sellers using their platforms. A seller using such a platform exclusively generally does not need to separately collect tax on those specific marketplace sales. However, the seller may still have other Texas tax obligations, and should confirm the specific collection arrangement for each platform used.
Does storing inventory in a Texas fulfillment center create nexus?
Generally, yes. Storing inventory in Texas, including inventory held through certain third-party fulfillment arrangements (such as Fulfillment by Amazon), generally creates physical presence nexus depending on the specific arrangement, regardless of the seller's overall revenue level. Sellers using fulfillment services should review their inventory location reports to identify any Texas-based storage.
How does drop shipping affect Texas sales tax obligations?
Drop shipping requires analyzing nexus separately for both the seller and the supplier. If the seller has Texas nexus, it generally must collect tax on the retail sale to the Texas customer regardless of where the supplier is located. If the supplier has Texas nexus and the seller does not provide a valid resale certificate, the supplier may be required to collect tax on the wholesale transaction, potentially resulting in tax effectively being collected at two points in the supply chain.
What sales tax rate should I charge on Texas e-commerce sales?
The applicable combined state-plus-local rate depends on Texas's specific sourcing rules, which can vary based on whether the seller has a Texas location and the nature of the transaction. The combined rate can range up to 8.25% depending on the local jurisdiction. Many online sellers use sales tax automation software to correctly apply sourcing rules across Texas's many local jurisdictions.
If a marketplace collects tax on my behalf, do I still need to file Texas sales tax returns?
It depends on the seller's overall Texas activity. A seller who sells exclusively through marketplace facilitators that collect and remit tax may have reduced or no direct filing obligation for those specific sales, but sellers with any direct (non-marketplace) Texas sales, or with other Texas nexus-creating activity, may still have filing obligations. Reviewing the seller's complete sales channel mix is recommended before concluding no filing is required.
What is a resale certificate and when do I need one as an online seller?
A resale certificate documents that a purchaser is buying goods for resale rather than as the end consumer, exempting that specific transaction from sales tax. Online sellers in drop shipping arrangements commonly need to provide resale certificates to their suppliers to avoid being charged tax on wholesale purchases. Sellers should verify the validity of certificates received from their own business customers and retain them for audit purposes.
How has the Wayfair decision affected online sellers?
The 2018 Supreme Court decision in South Dakota v. Wayfair, Inc. allowed states to require sales tax collection based on economic activity rather than only physical presence. Texas and most other states subsequently enacted economic nexus laws. As a result, online sellers with significant sales into a state — even without any physical presence there — may be required to register and collect that state's sales tax.
