Hello! Welcome to the final lesson in our "Sourcing, Compliance, and Supplier Vetting" module.
In our last lesson, we focused on getting your products into the United States by navigating import compliance, including HTS codes, duties, and safety certifications. Now, we'll shift our focus to the rules you must follow when selling within the US. Mastering this is just as critical for building a sustainable, long-term e-commerce business.
Today, your learning outcome is to understand US domestic compliance: sales tax permits and authorized reseller agreements. We will break down what these mean for you as a remote seller using major marketplaces and how they directly impact your profitability and business legitimacy.
1. Demystifying US Sales Tax for Online Sellers
Sales tax in the United States can seem incredibly complex, with different rules in every state. However, for a seller using marketplaces like Amazon and Walmart, the situation is much simpler than it first appears.
Let's start by understanding the core concept that determines if you need to collect sales tax: nexus. Nexus is simply a connection between your business and a state that obligates you to follow that state's tax laws.
The video below from LedgerGurus gives an excellent overview of the two types of nexus you need to be aware of.

Watch this clip to understand the two fundamental types of sales tax nexus: physical and economic. This will form the foundation for everything else we discuss about sales tax.
Watch from the beginning to 05:32. Pay attention to: Physical Nexus (00:50): How your physical presence (people, inventory) creates a tax obligation. Economic Nexus (02:32): How your sales volume or number of transactions into a state can create a tax obligation, even with no physical presence.
So, to recap:
- Physical Nexus: You have a physical connection. For an e-commerce seller, this is typically where you live, or more importantly, where your inventory is stored. If you use Amazon FBA, your inventory could be in warehouses in many different states, creating physical nexus in all of them.
- Economic Nexus: You have a significant economic connection. This is triggered by exceeding a certain amount of sales (e.g., $100,000) or a number of transactions (e.g., 200) in a state within a year.
The Game Changer: Marketplace Facilitator Laws
Now for the most important piece of information for your business model: Marketplace Facilitator Laws. These laws require marketplaces like Amazon, Walmart, and TikTok to collect and remit sales tax on behalf of their third-party sellers.
This radically simplifies your tax obligations. Instead of you having to register in every state where you have nexus and handle the taxes, the platform does it for you.
Let's continue with the same video to see this explained.
Online Sales Tax: The COMPLETE GUIDE for ecommerce sellers
This next clip is crucial. It explains how marketplace facilitators completely change the game for sales tax compliance.
Watch from 06:48 to 10:32. Focus on the two key questions to ask yourself: 'Are my products taxable?' and 'Am I selling through a marketplace facilitator?' This section will clarify why you likely won't be remitting sales tax yourself for most of your sales.
To see this in action, let's look at Walmart's own documentation.
Sales tax collection - Guides | Marketplace Learn
This guide from Walmart's Seller Help center explicitly confirms their role as a marketplace facilitator.
Briefly review the introduction and the table of states. Notice that Walmart collects and remits sales tax in nearly every state that has a sales tax. This is direct confirmation of the marketplace facilitator principle.
As you can see, for sales made on these major platforms, the burden of calculating, collecting, and remitting sales tax is handled for you.
2. The Real Reason You Need a Sales Tax Permit: The Resale Certificate
If the marketplaces handle sales tax, you might be wondering why you would even need a sales tax permit. The primary reason is not for remitting tax on your sales, but for sourcing products tax-free.
When you register for a sales tax permit in a state, you are typically issued a resale certificate. This is a legal document that allows you to buy goods from suppliers (like wholesalers, manufacturers, or even other retailers in an arbitrage model) without paying sales tax, on the basis that you intend to resell those goods.
This is a huge advantage for your cash flow and profit margins. If you're buying $10,000 worth of inventory and the sales tax rate is 8%, a resale certificate saves you $800 upfront.
Here is an example of what a Sales and Use Tax Permit looks like.
How to Use Your Resale Certificate
Let's look at a very practical, hands-on example. If you plan to use retail or online arbitrage (buying from a retailer like Walmart to sell on another platform like Amazon), you'll need to provide your resale certificate to the source retailer.
This video walks you through the exact process for getting tax-exempt status on Walmart.com, a common sourcing site for resellers.
How to Get Sales Tax Exempt at Walmart Step-by-Step
This video from 'Fields of Profit' is a step-by-step tutorial on how to apply your sales tax permit to become tax-exempt when purchasing from Walmart.com. This is a perfect, practical application of the concepts we've just discussed.
Watch from 01:22 to 04:03. The video shows: The need to first obtain a sales and use tax permit from your state (01:22). How to fill out the Walmart tax-exempt application online (02:29). Where to upload your permit document to complete the process (03:22).
As the video mentions, to get a sales tax permit, you first need a registered business entity with an EIN, which you covered back in Module 1. You would then apply for the permit through the Department of Revenue (or equivalent agency) in the state where your business is registered.
Test your understanding!
You have set up your US LLC in Wyoming. You plan to buy products from a wholesaler in California and have them shipped to an Amazon FBA warehouse in Texas. You will then sell these products on Amazon.com to customers all over the US.
Where do you need to worry about sales tax?
Show answer
There are two parts to this:
- Buying from the Wholesaler: To avoid paying California sales tax on your bulk purchase, you will need to provide the wholesaler with a valid resale certificate. Your Wyoming permit may be accepted, but some states require you to register there. This is where you would check state-specific rules.
- Selling to the End Customer: You don't need to worry about this. Amazon, as the marketplace facilitator, will automatically collect and remit the correct sales tax from the customer based on their location and send it to the appropriate state.
3. Building a Legitimate Business: Authorized Reseller Agreements
The second pillar of domestic compliance is your relationship with the brands you sell. Simply buying a product and listing it online isn't always enough to build a stable business, especially on platforms like Amazon and Walmart. Many brands want to control who sells their products, leading to the concept of an authorized reseller.
Online Authorized Retailer: What It Is & How to Become One
This article from SimplyDepo clearly defines what an authorized retailer is and why it's a superior, more sustainable business model than unauthorized selling.
Read the first two main sections: 'What Is an Online Authorized Retailer?': Understand the definition and the key differences from a generic seller. 'How to Become an Online Authorized Retailer': Review the 5-step process. This is your practical roadmap.
Why Being Authorized is Critical
- Avoid Account Suspension: Brands actively patrol marketplaces for unauthorized sellers. If a brand files an intellectual property (IP) complaint against your listing, your account could be suspended. An authorized reseller agreement is your proof that you have the right to sell the product.
- Access to Legitimate Supply: You buy directly from the brand or their approved distributors, guaranteeing authentic products.
- Adherence to Pricing Policies (MAP): Most authorized reseller agreements require you to follow a Minimum Advertised Price (MAP) policy. This prevents price wars that destroy profit margins and protects the brand's value.
- Credibility and Trust: It builds a professional, long-term business that is less vulnerable to sudden changes or takedowns.
The Risks of Unauthorized Selling
While sourcing models like retail arbitrage can be profitable, they carry inherent risks. You could be selling a product without the brand's permission, which can lead to:
- IP complaints and account suspension.
- Inability to provide proof of authenticity if challenged by a marketplace.
- No access to manufacturer warranties, leading to unhappy customers.
For long-term, scalable success, building relationships with brands and becoming an authorized reseller for your key products is the most secure path.
Conclusion
You have now covered the essentials of domestic compliance, giving you a framework for operating legally and professionally within the US market.
Key Takeaways:
- Marketplace Facilitator Laws are your friend: For sales on Amazon, Walmart, and TikTok, the platform handles the complex work of collecting and remitting sales tax.
- A Sales Tax Permit is for sourcing: Your primary need for a permit is to obtain a resale certificate, which allows you to buy inventory for resale without paying sales tax.
- Being an Authorized Reseller is the goal for stability: While you might start with other sourcing methods, becoming an authorized reseller protects you from IP complaints, ensures product authenticity, and builds a sustainable business.
