Why Walmart Marketplace Sellers in Greece Need an ITIN
Walmart requires all third-party sellers to have a U.S. Employer Identification Number (EIN) for onboarding, which in turn necessitates a U.S. tax identification number for the responsible party if they are not a U.S. citizen or resident. For sellers based in Greece, this typically means obtaining an Individual Taxpayer Identification Number (ITIN) if you do not qualify for a Social Security Number (SSN). The friction point arises when you attempt to register on the Walmart marketplace, and the system flags the absence of a U.S. tax ID. This is distinct from a general need for an ITIN, as it's directly tied to operating a U.S.-based e-commerce business through a platform that mandates U.S. tax compliance. Without the correct U.S. tax identification, your ability to sell on Walmart is blocked, impacting your business operations and revenue streams. The ITIN serves as your unique identifier for U.S. tax purposes, enabling you to file necessary returns and comply with IRS regulations related to your U.S. business activities.
ITIN Eligibility and Triggers for Greek Walmart Sellers
An ITIN is required for individuals who need to file a U.S. tax return or are claiming tax treaty benefits but do not have, and are not eligible to obtain, a Social Security Number (SSN). For Walmart marketplace sellers in Greece, the primary trigger for needing an ITIN is the requirement to obtain a U.S. EIN. While the EIN is for a business entity, the responsible individual behind that entity often needs an ITIN if they are a non-U.S. person. If you are operating a U.S. LLC or other business structure to sell on Walmart, and you are not a U.S. citizen or Green Card holder, you will likely need an ITIN. This is because the IRS requires accurate identification for tax purposes, and an ITIN fulfills this role for non-residents. Even if your business activities generate minimal U.S. income, platform requirements and potential treaty benefits necessitate proper identification. The Greece–U.S. tax treaty may offer benefits, but claiming them often requires filing a U.S. tax return, thus requiring an ITIN.
Required Documentation for Your ITIN Application
To apply for an ITIN, you must submit IRS Form W-7, Application for IRS Individual Taxpayer Identification Number. This form requires you to provide your full legal name, foreign address, and other personal details. Alongside the Form W-7, you must submit original identification documents or certified copies. The IRS prefers a valid, unexpired passport as the primary form of identification. If a passport is not available, other documents like a national identity card, birth certificate, or driver's license may be accepted, provided they meet specific IRS criteria. You will also need to include documentation that proves your U.S. tax liability or need for an ITIN. For Walmart sellers, this often means including a copy of your U.S. tax return (e.g., Form 1040-NR for non-resident aliens) or documentation demonstrating your business activity that necessitates the ITIN. Ensure all submitted documents are accurate and match your legal name precisely to avoid delays.
The ITIN Application Process and Timeline
The ITIN application process begins with completing Form W-7. You have two primary methods for submitting your application: directly to the IRS or through a Certified Acceptance Agent (CAA). Submitting directly to the IRS involves mailing your original identification documents and supporting tax forms to the IRS ITIN Operation in Austin, Texas. This method can lead to longer processing times and the risk of losing original documents. Alternatively, you can apply through a CAA, such as itin.net. A CAA authenticates your original identification documents, verifies your application, and forwards it to the IRS. This process typically takes 5–10 business days for the IRS to issue an ITIN once they receive the application from the CAA. The IRS will mail your ITIN directly to you. Processing times can fluctuate based on IRS workload, so applying early is always advisable. After receiving your ITIN, you can finalize your U.S. business setup and begin selling on Walmart.
Common Mistakes for Greek Walmart Sellers
Walmart marketplace sellers from Greece often encounter specific pitfalls during the ITIN application. A frequent error is failing to include a complete U.S. tax return with the Form W-7 application when required. Since your business is on Walmart, you must demonstrate why you need an ITIN, often tied to filing a U.S. tax return. Another common mistake is mismatched information across documents; ensure your name on the Form W-7, passport, and any other submitted IDs is identical. Mailing original documents directly to the IRS without using a CAA poses a risk of loss and significantly extends processing time. For those aiming to claim benefits under the Greece–U.S. tax treaty, incorrect treaty claims on Form W-7 can lead to rejection or further IRS scrutiny. Lastly, incomplete or inaccurate personal details on the Form W-7 itself are a primary cause of delays or denials. Double-checking every field is essential.
Benefits of Using a Certified Acceptance Agent (CAA)
Applying for an ITIN through a Certified Acceptance Agent (CAA) offers significant advantages, especially for international sellers. A CAA, like itin.net, is authorized by the IRS to authenticate your original identification documents, such as your passport. This means you do not have to mail your original, irreplaceable documents to the IRS, mitigating the risk of loss or theft. The CAA reviews your entire application package, including Form W-7 and supporting tax documents, ensuring it is complete and accurate before submitting it to the IRS. This pre-screening process dramatically reduces the chances of application errors and subsequent delays. The typical processing time when using a CAA is much faster, generally 5–10 business days from IRS receipt of the application, compared to potentially months when applying directly. This efficiency is crucial for Walmart sellers needing to establish their U.S. tax identity promptly to commence or continue their business operations.
Next Steps After Obtaining Your ITIN
Once you receive your ITIN from the IRS, you can proceed with finalizing your U.S. business operations for Walmart. Use your ITIN to complete any outstanding requirements for your U.S. LLC or business entity setup. If you haven't already, you can now open a U.S. bank account using your ITIN and EIN, which is essential for managing your Walmart sales revenue. With your ITIN and EIN in hand, you are fully compliant for tax purposes with the IRS regarding your U.S. marketplace activities. Prepare to file your U.S. federal income tax return annually, reporting any U.S. source income.

Practical tips
- Use the same legal name across Form W-7, your passport, and any prior IRS correspondence — mismatched name fields are the most common rejection.
- If you are applying for an ITIN for yourself and your spouse or dependents, submit a separate Form W-7 for each individual.
- Ensure your passport is valid and has not expired. Expired identification documents are not accepted by the IRS for ITIN applications.
- When completing Form W-7, accurately report your foreign address. Do not use a U.S. address unless you have specific IRS authorization.
- Keep copies of all documents submitted with your ITIN application, including your Form W-7 and supporting identification, for your records.
Frequently asked questions
Do I need an ITIN if I already have an EIN for my Walmart business?
Yes, if you are a non-U.S. person operating a U.S. business entity (like a U.S. LLC) to sell on Walmart, you will likely need an ITIN for yourself, even if the business has an EIN. The EIN identifies the business, while the ITIN identifies you as an individual for tax purposes related to that business.
Can I use my Greek passport to apply for an ITIN?
Yes, a valid, unexpired Greek passport is the preferred identification document for applying for an ITIN. It is accepted by the IRS as proof of identity and nationality.
How long does it take to get an ITIN through itin.net?
When applying through itin.net as a Certified Acceptance Agent (CAA), the IRS typically processes ITIN applications within 5–10 business days after receiving the complete package. The verification of your documents by the CAA adds a small amount of time before submission.
What U.S. tax return should I submit with my ITIN application for Walmart sales?
If you are a non-resident alien deriving U.S. income from your Walmart sales, you will generally need to file Form 1040-NR, U.S. Nonresident Alien Income Tax Return. Your specific tax situation might vary, so consult with a tax professional. The completed tax return is a key document for your ITIN application.
Can I open a U.S. bank account with my ITIN and EIN?
Yes, once you have both your ITIN and EIN, you can open a U.S. bank account. Many U.S. banks and financial services, such as Mercury, Relay, or Brex, cater to international entrepreneurs and require these identification numbers.
What happens if my ITIN application is rejected?
If your ITIN application is rejected, the IRS will send you a letter explaining the reason. Common reasons include missing documentation, incorrect information on Form W-7, or failure to include the required tax return. You will need to correct the issues and resubmit your application. Using a CAA like itin.net can help prevent rejections by ensuring your application is complete and accurate before submission.
