US Sales Tax for NRI E-Commerce Sellers: A Complete Guide

Unlike income tax, there is no federal sales tax in the United States. Sales tax is imposed by individual states, counties, and cities. This means:

• There is no single sales tax rate — rates vary by jurisdiction
• Each state has its own rules for what is taxable and what is exempt
• You may need to register, collect, and file in multiple states simultaneously
• 5 states have no sales tax at all: Oregon, Montana, New Hampshire, Delaware, and Alaska (Alaska has no state sales tax but allows local jurisdictions to impose sales tax)

### How Sales Tax Works

Sales tax is a consumption tax collected from the buyer at the point of sale. As the seller, you are responsible for:

1. Determining whether the transaction is taxable
2. Calculating the correct tax rate based on the buyer's location (destination-based sourcing, used by most states)
3. Collecting the tax from the buyer
4. Remitting the collected tax to the state tax authority
5. Filing periodic sales tax returns

You are not paying sales tax out of your own pocket. You are collecting it from customers and passing it through to the state. However, if you fail to collect it when required, you become personally liable for the uncollected amount.

Before 2018, a state could only require you to collect sales tax if you had a physical presence (office, warehouse, employees) in that state. The landmark US Supreme Court decision in South Dakota v. Wayfair, Inc. (2018) changed everything.

### The Wayfair Decision

The Court ruled that states can require remote sellers — including sellers with no physical presence in the state — to collect sales tax if they exceed an economic nexus threshold in that state.

### Economic Nexus Thresholds by State

Most states have adopted one or both of these thresholds:

Examples of state-specific thresholds:

Key point for NRI sellers: You do not need to be physically present in the US to trigger economic nexus. If your Amazon or Shopify store sells $100,000 worth of products to customers in Texas, you have economic nexus in Texas and must collect Texas sales tax — even if you are operating entirely from India.

---

Economic nexus is not the only trigger. Physical nexus still applies and is particularly relevant for NRI sellers who use fulfillment services.

### Amazon FBA Creates Physical Nexus

If you use Fulfillment by Amazon (FBA), Amazon stores your inventory in warehouses across multiple states. Having inventory stored in a state creates physical nexus in that state, regardless of your sales volume there.

Amazon operates fulfillment centers in approximately 30+ states. This means an FBA seller can have physical nexus in dozens of states simultaneously, even with modest sales volume.

### Other Physical Nexus Triggers

• Inventory stored in any third-party warehouse (not just Amazon)
• Employees, agents, or contractors operating in the state
• Attending trade shows in certain states (varies by state and duration)
• Drop-shipping from a supplier located in the state (in some jurisdictions)

---

This is the most important compliance development for NRI e-commerce sellers. Marketplace facilitator laws shift the sales tax collection responsibility from the seller to the marketplace.

### How It Works

As of 2026, virtually all states with sales tax have enacted marketplace facilitator laws. Under these laws, if you sell through a marketplace (defined as a platform that facilitates the sale and processes the payment), the marketplace is responsible for:

• Calculating sales tax
• Collecting sales tax from the buyer
• Remitting sales tax to the state
• Filing sales tax returns for marketplace sales

### Platforms That Collect as Marketplace Facilitators

• Amazon — collects and remits in all states with marketplace facilitator laws
• Walmart Marketplace
• eBay
• Etsy
• Shopify (only when using Shopify's marketplace features or Shop app — not for sales through your own Shopify store)

### When You Must Still Collect Yourself

Marketplace facilitator laws only cover sales made through the marketplace. If you also sell through:

• Your own website (including your Shopify-hosted store with your own domain)
• Direct invoicing to clients
• Wholesale channels
• Any other non-marketplace channel

Then you are responsible for collecting and remitting sales tax on those sales. You must track your own non-marketplace sales against economic nexus thresholds in each state.

Practical example: You sell $80,000 through Amazon (Amazon collects sales tax) and $30,000 through your own Shopify website into California. Your total sales into California are $110,000, but Amazon handled $80,000. You still have economic nexus in California based on total sales, and you must collect sales tax on the $30,000 in direct website sales.

Before you can legally collect sales tax, you must register for a sales tax permit (also called a seller's permit, certificate of authority, or sales tax license) in each state where you have nexus.

### Registration Process

1. Determine nexus states — List every state where you have economic or physical nexus
2. Register with each state's Department of Revenue — Most states offer online registration
3. Receive your permit number — This is required before you begin collecting
4. Configure your sales tax settings — In your e-commerce platform or accounting software

### Key Information Required for Registration

• LLC name and EIN (Employer Identification Number)
• Business address (your US registered agent address is typically acceptable)
• NAICS code (industry classification)
• Expected monthly/annual sales volume in the state
• Start date of sales activity in the state

### Important Warning

Do not collect sales tax without a valid permit. In most states, collecting sales tax without being registered is illegal. Register first, then begin collecting.

### Streamlined Sales Tax (SST)

If you have nexus in many states, the Streamlined Sales and Use Tax Agreement (SSTUA) allows you to register in 24 member states simultaneously through a single application at sstregister.org. This saves significant time compared to registering in each state individually.

---

Sales tax rates are not simple. The total rate a customer pays is the combination of:

### Combined Rate Examples

There are over 11,000 sales tax jurisdictions in the United States. Manual rate calculation is not feasible for any seller with meaningful volume. This is why automated sales tax software is essential (covered in Section 9).

### Destination vs Origin-Based Sourcing

• Destination-based (most states): Tax rate is based on where the buyer is located
• Origin-based (fewer states, including Texas, Pennsylvania, Ohio): Tax rate is based on where the seller is located

As an NRI seller shipping from a US fulfillment center, your "origin" for origin-based states is typically the fulfillment center's location.

---

Not everything is taxable. Most states exempt certain categories of goods:

### Resale Exemptions

If you sell to another business that will resell the product, the buyer can provide a resale certificate (also called an exemption certificate). You do not collect sales tax on resale transactions. Keep the resale certificate on file — the burden of proof is on you if audited.

---

Each state assigns you a filing frequency based on your sales volume in that state:

### Zero Returns

If you are registered in a state but had no taxable sales during a filing period, you must still file a zero return by the deadline. Failure to file — even with no tax due — results in penalties and may trigger the state to estimate your liability and send a bill.

### Late Filing Penalties

Penalties for late filing or failure to remit collected sales tax vary by state but typically include:

• Late filing penalty: 5-25% of tax due
• Late payment penalty: 5-10% of unpaid tax
• Interest: Prime rate + 3-5% (compounds monthly in some states)
• Criminal penalties: Collecting sales tax and not remitting it is considered theft of government funds in most states — a criminal offense

---

Given the complexity of multi-state sales tax compliance, automated software is not a luxury — it is a necessity for any seller with nexus in more than one or two states.

### Recommendation for NRI Sellers

If you sell primarily through your own website (Shopify), start with Shopify Tax for rate calculation and use TaxJar for multi-state filing automation. If you sell across multiple platforms and channels, TaxJar or Avalara can handle the full workflow from calculation to filing.

### Nexus When Operating from India

Your physical location in India does not create sales tax nexus in any US state. Nexus is triggered only by US-based activity: sales volume into the state (economic nexus) or physical presence in the state (inventory, employees, fulfillment centers).

However, do not assume you are exempt. Most NRI e-commerce sellers trigger nexus through one or both of:

• Economic nexus — $100K+ in sales into a state
• FBA inventory — physical nexus in every state where Amazon stores your products

### US Registered Agent Is Not Nexus (Usually)

Having a registered agent for your LLC in a state (required for LLC formation) does not by itself create sales tax nexus in most states. A registered agent's sole function is to receive legal documents, which does not constitute a business presence.

### Sales Tax vs Income Tax

Sales tax nexus and income tax nexus are different concepts with different rules. Having sales tax nexus in a state does not automatically mean you owe income tax in that state (and vice versa). However, significant economic activity in a state may trigger both.

### No VAT/GST in the US

If you are familiar with India's GST or the EU's VAT system, note that the US has no equivalent national consumption tax. Sales tax is the closest analog, but it is collected by the seller (not remitted through an input credit chain) and operates at the state level.

### Does my NRI-owned LLC need to collect US sales tax?

It depends on whether you have nexus in any state. If you sell more than $100,000 (or meet the transaction threshold) into a state, or if you have inventory stored in a state (e.g., through Amazon FBA), you likely have nexus and must collect and remit sales tax in that state.

### Does Amazon collect sales tax for me?

Yes — if you sell through the Amazon marketplace, Amazon collects and remits sales tax on your behalf in all states with marketplace facilitator laws (which is virtually all states with sales tax). However, if you also sell through your own website or other non-marketplace channels, you are responsible for collecting sales tax on those sales.

### Which states have no sales tax?

Five states have no state-level sales tax: Oregon, Montana, New Hampshire, Delaware, and Alaska. However, Alaska allows local jurisdictions to impose local sales tax, so some Alaska locations do have sales tax.

### How many states do I need to register in?

Only the states where you have nexus — either economic nexus (exceeding the sales or transaction threshold) or physical nexus (inventory, employees, etc.). Use a nexus analysis tool like TaxJar's nexus tracker to identify your obligation states. For FBA sellers, this could be 20-30+ states.

### What happens if I do not collect sales tax when I should?

You become personally liable for the uncollected tax. The state can assess the tax amount plus penalties (5-25%) and interest. In egregious cases, willfully failing to collect and remit sales tax is a criminal offense. Most states also offer voluntary disclosure agreements (VDAs) for sellers who come forward to register and pay past-due tax — this typically reduces penalties.

### Do I need to charge sales tax on shipping?

It varies by state. Some states tax shipping charges; others do not. Examples:

• Taxable: California (if goods are taxable), New York, Texas
• Exempt: Colorado, Florida, Massachusetts (if separately stated)

Your sales tax software will handle this automatically based on the customer's state.

### Is there sales tax on digital products?

It varies significantly by state. Some states tax digital goods (e-books, music, software downloads, streaming services) while others exempt them. If you sell digital products, consult a state-by-state guide or use automated software that accounts for digital goods taxability.

### How do I handle sales tax refunds or returns?

When you refund a customer, you are also refunding the sales tax collected. You can claim a credit on your next sales tax return for the refunded tax amount. Your e-commerce platform typically tracks this automatically.
