Walmart Marketplace Sellers in the UK Face Unique ITIN Hurdles

Walmart’s requirement for a U.S. business entity and an Employer Identification Number (EIN) for onboarding creates a specific hurdle for sellers based in the United Kingdom. While many non-residents might need an ITIN for various U.S. income-related activities, Walmart marketplace sellers specifically encounter this need as part of establishing their U.S. business presence. Unlike sellers operating solely within the UK or on non-U.S. platforms, you must engage with U.S. tax and business registration processes. This often means obtaining an ITIN to satisfy IRS requirements indirectly linked to your U.S. business operations, even if you are not physically present in the U.S. The complexity arises because the ITIN is an individual tax ID, but it’s often a necessary step for business-related activities, especially when forming a U.S. entity like a U.S. LLC. Understanding this distinction is critical for a smooth onboarding process. You are not just applying for a tax ID; you are fulfilling a prerequisite for operating a U.S.-based e-commerce business.

When an ITIN Becomes Necessary for UK Walmart Sellers

An ITIN is required for United Kingdom-based Walmart marketplace sellers primarily when establishing a U.S. business entity, such as a U.S. LLC, to sell on the platform. Walmart’s onboarding process mandates a U.S. business registration and an EIN. While the EIN is for the business entity, the individuals who own or operate that entity may need an ITIN if they do not have a Social Security Number (SSN). This is particularly true if the business income flows through to you personally and requires U.S. tax reporting. The IRS issues an ITIN to individuals who have a U.S. tax filing obligation but are ineligible for an SSN. For UK sellers, this situation commonly arises when setting up the U.S. business structure needed to partner with Walmart. Without an ITIN, you may be unable to complete the necessary U.S. tax forms or business registrations that are prerequisites for selling on major U.S. marketplaces. The need for an ITIN is thus a direct consequence of the business structure required by platforms like Walmart.

Essential Documents for Your ITIN Application

To apply for an ITIN using IRS Form W-7, you must submit original or certified copies of specific identification documents. The most critical documents include a completed Form W-7 application, your foreign tax return (if applicable), and proof of your identity and foreign status. For individuals based in the United Kingdom, a valid passport is the preferred identification document. This single document serves as both proof of identity and foreign status. If a passport is unavailable, other documents such as a national identity card, a driver's license, or birth certificate may be considered, but these must be presented in combination with other supporting evidence to establish foreign status. Ensure that the name and identifying information on all submitted documents are identical to prevent application delays. The IRS requires these documents to verify your identity and to ensure you have a legitimate need for a U.S. tax identification number. Missing or inconsistent documentation is a primary reason for application rejection.

The ITIN Application Process for UK Sellers

The ITIN application process begins with completing IRS Form W-7. This form requires detailed personal information, including your name, address, and U.S. tax identification number (if you have one). For Walmart sellers in the United Kingdom, the primary reason for applying is usually to support the U.S. business entity setup. After completing Form W-7, you must gather your supporting identification documents, such as a valid passport. You then have two main options for submitting your application. The first is to mail the completed Form W-7 and original identification documents directly to the IRS in Austin, Texas. This method carries the risk of losing original documents and can have significantly longer processing times. The second, and often preferred, method is to apply through a Certified Acceptance Agent. A CAA, like itin.net, can verify your original documents and forward your application to the IRS, eliminating the need to mail your originals. This process through a CAA typically takes 5–10 business days for the IRS to issue the ITIN, compared to potentially several weeks or months if mailing directly.

Common Pitfalls for UK Walmart Sellers Applying for an ITIN

Walmart marketplace sellers from the United Kingdom often encounter specific application errors. A frequent mistake is failing to include a U.S. tax return or a statement explaining why you are not required to file one, which is a standard requirement for the Form W-7. For sellers establishing a U.S. entity, this might be tied to the initial business registration or income projections. Another common issue is inconsistent personal information across documents. Ensure your name, date of birth, and other identifying details match exactly between your passport, Form W-7, and any other submitted documentation. Incorrectly claiming tax treaty benefits, if applicable to your personal income, can also lead to rejection. While the UK-U.S. tax treaty offers specific provisions, claiming them requires careful adherence to IRS guidelines and specific treaty articles. Lastly, submitting incomplete or incorrect supporting documentation, such as expired identification or missing pages from a passport, will cause delays or outright rejection of your ITIN application. Double-checking all requirements before submission is essential.

The Certified Acceptance Agent (CAA) Advantage

Applying for an ITIN through a Certified Acceptance Agent, such as itin.net, offers distinct advantages for Walmart sellers in the United Kingdom. The most significant benefit is that a CAA can authenticate your original identification documents. This means you do not have to mail your passport or other vital original documents directly to the IRS, mitigating the risk of loss or theft during transit. Instead, the CAA reviews your documents, verifies their authenticity, and forwards certified copies along with your application to the IRS. This verification process by the CAA streamlines the application, often leading to faster processing times. While the IRS processing itself can still take time, the CAA’s involvement ensures that your application package is complete and correctly submitted from the outset, reducing the likelihood of administrative delays or rejections due to documentation errors. This specialized service provides peace of mind and efficiency, which is invaluable when navigating U.S. business requirements.

Next Steps After Obtaining Your ITIN

Once you receive your ITIN from the IRS, typically via IRS notice CP-565, you can proceed with the necessary steps to fully establish your U.S. business presence for Walmart. This usually involves using your ITIN in conjunction with your business entity's details to finalize your EIN application if you haven't already obtained one. With both your ITIN and EIN in hand, you can then open a U.S. bank account, which is another common requirement for U.S. marketplace sellers. These steps collectively enable you to complete the Walmart onboarding process and begin selling. For those who are ready to start this process, itin.net offers a Standard Package for ITIN applications at $497. If you require assistance or have complex questions, contacting us directly is recommended. You can also review our pricing for renewal services if you have a previously issued ITIN.

Practical tips

  • Use your full legal name on Form W-7 exactly as it appears on your passport or other primary identification document.
  • Ensure your application for an ITIN is accompanied by a U.S. federal tax return, or a statement explaining why you are not required to file one.
  • When applying through a Certified Acceptance Agent, provide your original identification documents for verification rather than sending copies.
  • If you are claiming tax treaty benefits, carefully review the specific articles of the UK-U.S. tax treaty and ensure your claim aligns with IRS requirements.
  • Keep copies of your submitted Form W-7 and all supporting documents for your personal records.

Frequently asked questions

Do I need an ITIN if I already have an EIN for my Walmart business?

An EIN is for your business entity, while an ITIN is for individuals. If you are a UK resident operating a U.S. LLC or other business entity to sell on Walmart, and you do not have an SSN, you will likely need an ITIN for personal tax reporting related to your business income or for certain state-level requirements, even if your business has an EIN.

Can I apply for an ITIN and an EIN at the same time?

Yes, you can apply for both. However, the process for obtaining an EIN for a U.S. business entity often requires the business owners to have an ITIN if they do not have an SSN. It is generally advisable to secure your ITIN first, especially if you are forming a new entity and need the ITIN for the EIN application process itself, or for personal tax filings associated with that entity.

How long does it take for the IRS to issue an ITIN?

When applying through a Certified Acceptance Agent like itin.net, the IRS typically processes ITIN applications within 5–10 business days. If you mail your application directly to the IRS, processing times can be significantly longer, potentially several weeks or even months, and you risk losing your original documents.

What is the cost for an ITIN application for a UK seller?

The IRS does not charge a fee to apply for an ITIN. However, if you use a Certified Acceptance Agent (CAA) service, like itin.net, there will be a fee for their verification and processing services. Our Standard Package is priced at $497.

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 incomplete forms, missing or invalid documentation, or incorrectly claimed tax benefits. You will need to correct the issues identified and resubmit your application. Using a CAA can help minimize the chances of rejection by ensuring your application is complete and accurate from the start.

Do I need to renew my ITIN?

An ITIN does not expire unless it is not used on a federal tax return for three consecutive tax years. If your ITIN has expired due to non-use, or if you need to update your personal information, you will need to go through the renewal process by submitting a new Form W-7 and updated documentation.
