ITIN for Amazon FBA Sellers: Complete 2026 Guide to Avoiding 30% Withholding

Why Do Amazon FBA Sellers Need an ITIN in 2026?

Amazon generated $574 billion in US e-commerce sales in 2023, and the IRS requires every seller earning income through US marketplaces to have a valid taxpayer identification number. For non-US residents without a Social Security Number, an ITIN is the only way to meet this requirement under IRC Section 1441. Amazon uses your ITIN to verify your identity, process your W-8BEN form, and determine the correct withholding rate on your earnings across all 20 Amazon US product categories.

Beyond tax compliance, your ITIN is the key that unlocks the full Amazon seller experience. Without it, you are operating at a significant financial disadvantage. Here are the specific reasons every non-US FBA seller needs an ITIN:

• Avoid 30% backup withholding on your gross sales revenue, not just profits
• Complete the tax interview in Seller Central by submitting a valid W-8BEN form
• Claim tax treaty benefits that may reduce your US tax obligation to 0%
• Receive full disbursements without Amazon holding a portion of every payout
• File US tax returns accurately using Form 1040-NR when required
• Open a US bank account to receive Amazon payouts directly without currency conversion delays

How Much Does Amazon Withhold Without an ITIN?

This is the single biggest financial hit for non-US Amazon sellers who operate without an ITIN. Under IRS rules, Amazon is required to withhold 30% of payments to foreign persons who have not provided valid tax identification. This withholding applies to your gross sales amount, not your net profit.

Let's look at a real example. Say you sell $15,000 worth of products in a month. Your cost of goods, Amazon fees, and shipping total $10,000, leaving you with $5,000 in actual profit. Without an ITIN, Amazon withholds 30% of $15,000, which is $4,500. Your $5,000 profit drops to just $500. With thin FBA margins, this can turn a profitable business into a money-losing one.

Once you have an ITIN and submit a W-8BEN form in Seller Central, the withholding rate drops based on your country's tax treaty with the US. For many countries, the rate on business profits drops to 0% because physical product sales through FBA are not considered US-source income if you have no permanent establishment in the US. The difference between 30% and 0% withholding is the difference between a viable business and a financial drain.

It is also worth noting that this withholding is not a final tax. If Amazon withholds 30% and your actual tax liability is lower (or zero), you can file a US tax return to claim a refund of the excess withholding. However, this process takes months and ties up your cash flow. It is far better to get your ITIN upfront and avoid the withholding entirely than to chase refunds after the fact.

This same withholding issue affects other platforms as well. If you also use PayPal or Stripe for other business activities, read our guide on ITIN for PayPal and Stripe to understand how tax identification works across all major payment processors.

How Do You Apply for an ITIN as an Amazon FBA Seller?

The ITIN application process involves submitting IRS Form W-7 along with supporting documents. Here is exactly how to do it as an Amazon FBA seller, from start to finish.

How Do You Set Up the W-8BEN in Amazon Seller Central?

Once you have your ITIN, the next step is completing the tax interview in Amazon Seller Central. This is where you submit your W-8BEN form, which tells Amazon your tax status and determines your withholding rate. The process takes about 10 minutes if you have your information ready.

Navigate to the tax interview: Log in to Seller Central, go to Settings, then click Account Info. Under the Tax Information section, click the Tax Interview button. Amazon will walk you through a series of questions about your tax status.

Select your status: Choose "No" when asked if you are a US person. Select "Individual" if you sell under your own name, or "Company" if you operate through a business entity. Enter your legal name exactly as it appears on your ITIN letter from the IRS.

Enter your ITIN: When prompted for a US taxpayer identification number, enter your 9-digit ITIN. This is the number that starts with 9 and has a 7 or 8 as the fourth digit (format: 9XX-7X-XXXX or 9XX-8X-XXXX). Amazon validates this number against IRS records.

Claim treaty benefits: If your country has a tax treaty with the US, check the box to claim treaty benefits. Select your country of residence and the applicable article number from the treaty. For most countries, business profits from product sales fall under Article 7 (Business Profits), which results in a 0% withholding rate when you have no US permanent establishment.

Submit and verify: Review all information, digitally sign the form, and submit. Amazon validates your W-8BEN within a few business days. Once verified, your withholding rate updates automatically on future disbursements.

Do You Need an ITIN or an EIN for Amazon FBA?

Many Amazon sellers are confused about whether they need an ITIN, an EIN, or both. The answer depends on your business structure. Here is a clear comparison:

If you are just starting out and selling under your own name, an ITIN is all you need for Amazon. If you plan to form a US LLC for liability protection and credibility, you will need both. Learn more about this distinction in our EIN application guide.

Which US Banks Work for Amazon FBA Sellers with an ITIN?

Amazon disburses your seller payments to a bank account, and having a US bank account simplifies this process significantly. International transfers involve currency conversion fees and delays that eat into your margins. With an ITIN, you can open a US bank account and receive Amazon payouts directly in USD.

Wise: The most popular option for international Amazon sellers. Wise provides a US bank account with routing and account numbers that work seamlessly with Amazon disbursements. You hold funds in USD and convert to your local currency at the mid-market rate when you are ready. Wise accepts ITIN holders and charges no monthly fees.

Payoneer: Another widely used option among Amazon FBA sellers. Payoneer integrates directly with Amazon and provides a US receiving account. Many sellers use Payoneer because of the direct Amazon partnership, though conversion fees tend to be slightly higher than Wise. Payoneer also offers a prepaid Mastercard that lets you spend your Amazon earnings directly without converting to your local currency first.

Mercury or Relay: If you have a US LLC with an EIN, you can open a full business bank account at Mercury or Relay. These offer standard banking features including ACH transfers, wire transfers, and debit cards. Both accept ITIN holders for the personal identification component of the application.

What Are the Tax Filing Requirements for Non-US Amazon FBA Sellers?

As a non-US seller earning income through Amazon, you have specific tax reporting obligations. Understanding these requirements helps you stay compliant and avoid penalties.

Form 1099-K: Amazon issues a 1099-K to sellers who meet certain thresholds (currently $600 in gross sales for US marketplace transactions). This form reports your gross sales amount to the IRS. Even though this form is technically for US persons, Amazon may issue information reporting for non-US sellers as well. Having your ITIN ensures this reporting is tied to your tax identity.

Form 1040-NR: If you have effectively connected income (income tied to a US trade or business), you must file a personal US tax return using Form 1040-NR. Whether your Amazon FBA income qualifies as effectively connected depends on your specific situation, including whether you have inventory stored in US warehouses (which FBA sellers do). Your ITIN goes on this form as your taxpayer identification number.

Form 5472 (for LLC owners): If you operate your Amazon business through a US LLC, you must file Form 5472 along with a pro-forma Form 1120 annually. The penalty for missing this filing is $25,000 per form per year, even if your LLC had no income. This applies to all foreign-owned single-member LLCs. For more details on LLC tax obligations, see our guide on ITIN for LLC owners.

Record keeping: Keep detailed records of all your Amazon transactions, costs of goods sold, shipping expenses, Amazon fees, and any other business expenses. These records are essential for accurate tax filing and for supporting any treaty claims you make on your W-8BEN.

If your ITIN has expired from non-use, our ITIN renewal guide covers the process step by step.

Do Amazon FBA Sellers Need to Worry About State Sales Tax?

State sales tax is separate from federal income tax, and it is one of the most confusing areas for international Amazon sellers. The good news is that Amazon handles most of the heavy lifting through its Marketplace Tax Collection (MTC) program. But there are still things you need to understand.

Marketplace Tax Collection: Amazon collects and remits sales tax on behalf of sellers in all states that have marketplace facilitator laws. As of 2026, this covers all 45 states (plus Washington D.C.) that charge sales tax. This means Amazon automatically adds the correct sales tax at checkout, collects it from the buyer, and pays it directly to the state. You do not need to register for sales tax permits in these states just because you sell through Amazon FBA.

Nexus and registration: Even though Amazon collects sales tax for you, having inventory stored in Amazon fulfillment centers across multiple states can create "nexus" (a tax presence) in those states. Some states may require you to register for a sales tax permit even if Amazon is collecting and remitting tax on your behalf. This is an evolving area of law, and requirements vary by state.

Resale Certificates: If you source inventory from US-based wholesalers or distributors, a Resale Certificate allows you to purchase products without paying sales tax upfront. You are buying the products for resale, not for personal use, so the tax is collected from the end consumer instead. Getting a Resale Certificate requires a state sales tax permit, which in turn requires a tax identification number like your ITIN.

State income tax: A few states also impose income tax on businesses with nexus in their state. If you have inventory in states like California or New York, you may have state income tax filing obligations in addition to federal requirements. A CPA familiar with multi-state e-commerce taxation can help you determine your specific obligations.

Practical tip: When you first set up your Amazon FBA account, Amazon distributes your inventory across fulfillment centers in multiple states to optimize delivery speed. You do not get to choose which states hold your inventory. This means you could potentially have nexus in 10 or more states depending on how Amazon routes your products. Keep track of which states hold your inventory by checking the Inventory Placement reports in Seller Central, and share this information with your tax professional annually.
