Why Stripe Account Holders in Portugal Need an ITIN
Stripe account holders based in Portugal face a specific friction point when managing their U.S. income: the requirement for a U.S. entity, an Employer Identification Number (EIN), and a U.S. bank account to operate fully on the platform. While Stripe Atlas can facilitate U.S. entity formation, obtaining an EIN via Form SS-4 and opening a U.S. bank account often necessitates a U.S. tax identification number if you are not a U.S. resident or citizen. This is where the Individual Taxpayer Identification Number (ITIN) becomes essential. The ITIN is a 9-digit IRS tax ID for individuals who must file U.S. taxes but cannot obtain a Social Security Number. For Portuguese residents earning U.S. income through Stripe, particularly if they are structuring their business with a U.S. entity or operating in a way that triggers U.S. tax obligations, the ITIN is not optional; it's a procedural necessity to meet platform and regulatory demands. Without it, you may encounter limitations in fully leveraging your Stripe account for global payment processing, especially concerning U.S. financial infrastructure requirements. This guide clarifies when and how to obtain your ITIN, specifically addressing the needs of Stripe users in Portugal.
ITIN Eligibility and Triggers for Portuguese Stripe Account Holders
You generally need an ITIN if you are a non-resident alien who has U.S. source income or is required to file a U.S. tax return, and you do not have and cannot get an SSN. For Stripe account holders in Portugal, this commonly arises in several scenarios. If your business structure involves a U.S. entity (like a U.S. LLC formed via Stripe Atlas or independently), you will likely need an ITIN to comply with U.S. tax reporting requirements, such as filing Form 5472 for foreign-owned U.S. disregarded entities. Even if you are operating as a sole proprietor receiving U.S. income, and that income is subject to U.S. tax withholding or you have other U.S. tax filing obligations, an ITIN is required. The U.S. tax treaty with Portugal is in force, which may affect your tax liability on U.S. source income, but it does not negate the need for an ITIN if a U.S. tax filing is mandatory. The IRS issues ITINs under their tax administration mandate, separate from immigration status or eligibility for an SSN. Therefore, the trigger is not simply earning income, but rather having a U.S. tax filing obligation or a requirement to have a U.S. taxpayer identification number for financial or reporting purposes related to your U.S. business activities facilitated by Stripe.
Required Documents 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, address, and other personal details. Alongside Form W-7, you must submit original or certified copies of identity documents. The most commonly accepted document is a valid passport, as it contains both your photograph and essential identifying information. If a passport is unavailable, other documents like a national identity card, driver's license, or birth certificate may be used, but you will likely need to provide additional documentation to verify your identity and foreign status. Crucially, you must also provide proof of your U.S. tax filing requirement. This typically means submitting a federal income tax return (e.g., Form 1040-NR for non-residents) along with your Form W-7, unless you qualify for an exception to this rule, such as certain treaty benefits or specific reporting requirements. Ensure all names on your supporting documents precisely match the name on your Form W-7. Mismatched names are a frequent cause for rejection.
The ITIN Application Process and Timeline
The application process for an ITIN involves submitting Form W-7 and supporting documentation to the IRS. You have two primary methods for submission. The first is directly to the IRS Service Center in Austin, Texas. This method requires you to mail original identity documents, which carries the risk of loss or delay, and processing times can be lengthy, often several months. The second, and generally recommended, method is through a Certified Acceptance Agent (CAA). As a CAA, itin.net can authenticate your original documents and forward your application package to the IRS without you having to mail your sensitive personal identification. This process significantly speeds up the timeline. When applying via a CAA, the IRS typically processes applications within 5–10 business days, and you will receive your ITIN via mail in a CP-565 letter. If you file directly with the IRS Service Center, expect a much longer waiting period, potentially 10–15 weeks or more, especially during peak tax seasons. It is advisable to apply well in advance of any deadlines related to your Stripe account or U.S. tax filings.
Common Mistakes for Portuguese Stripe Account Holders
Stripe account holders in Portugal often encounter specific pitfalls when applying for an ITIN. A frequent error is failing to include a complete U.S. federal income tax return with Form W-7, unless an exception applies. For instance, if you are forming a U.S. LLC and need an ITIN for Form 5472 reporting, you might not need to file a personal 1040-NR immediately, but you must clearly state the reason for needing the ITIN on the W-7. Another common issue is incorrect treaty claims. While Portugal has a tax treaty with the U.S., claiming treaty benefits on Form W-7 requires precise understanding and documentation, often involving specific IRS forms or statements. Incomplete or inaccurate personal information on Form W-7, especially name discrepancies between your form and your passport, leads to delays or rejections. Lastly, many applicants mistakenly believe they can use photocopies of their passport; the IRS requires either original documents or certified copies from the issuing agency when applying directly, though CAAs can verify originals on your behalf. These specific errors can jeopardize your ability to meet Stripe’s requirements or U.S. tax obligations.
Benefits of Using a Certified Acceptance Agent (CAA)
Applying for an ITIN through a Certified Acceptance Agent (CAA) like itin.net offers distinct advantages, particularly for Stripe account holders in Portugal. The most significant benefit is the avoidance of mailing original identity documents to the IRS. When you use a CAA, they are authorized by the IRS to verify your original documents, such as your passport, and return them to you immediately. The CAA then transmits certified copies along with your Form W-7 application to the IRS. This drastically reduces the risk of your critical documents being lost or stolen in transit. Furthermore, CAAs are trained to help ensure your Form W-7 is correctly completed and that you are submitting the necessary supporting documentation for your specific situation. This expertise helps prevent common errors that can lead to application delays or rejections. The expedited processing through a CAA means you can obtain your ITIN much faster, typically within 5–10 business days of the IRS receiving your application, allowing you to proceed with your U.S. business and financial setup more quickly. This efficiency is invaluable for entrepreneurs needing to finalize their Stripe account configurations.
Next Steps After Obtaining Your ITIN
Once you receive your ITIN from the IRS via a CP-565 letter, you can proceed with fulfilling the requirements for your Stripe account and any other U.S. financial or tax obligations. This includes providing your ITIN to Stripe if required for entity verification or tax withholding purposes. If you formed a U.S. LLC, you will use your ITIN to ensure accurate tax filings, such as Form 5472. You may also need it to open a U.S. bank account if you haven't already done so, although some banks may have specific requirements. Remember that your ITIN is a tax processing number, not an identity document for general purposes. It is essential for U.S. tax filing and reporting. If you anticipate needing to renew your ITIN or if your circumstances change, consult the IRS guidelines or seek professional advice. For those who have successfully obtained their ITIN and are ready to establish their U.S. business presence further, exploring options like an EIN for a U.S. entity or a U.S. bank account is often the logical next step.

Practical tips
- Ensure the legal name on your Form W-7 precisely matches your passport or other primary identification document. Any discrepancy can cause significant delays or rejection.
- If you are applying for an ITIN to meet U.S. LLC reporting requirements (Form 5472), clearly state this purpose on Form W-7, Box 6. You may not need to file a full Form 1040-NR.
- Gather all required supporting documents, including your passport and any other identity documents, before starting your Form W-7 application to avoid errors.
- When using a Certified Acceptance Agent (CAA), confirm they are authorized by the IRS. This verification ensures they can properly authenticate your documents and expedite your application.
- Understand that an ITIN is for tax processing purposes only. It does not grant work authorization or confer any immigration status in the United States.
Frequently asked questions
Can I use my Portuguese NIF (Número de Identificação Fiscal) instead of an ITIN for my Stripe account?
No, your Portuguese NIF is for tax purposes in Portugal. Stripe and U.S. tax authorities require a U.S. taxpayer identification number, such as an ITIN or an EIN, for individuals and entities operating within the U.S. financial system or subject to U.S. tax laws.
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 the application is received by the IRS. You will then receive your ITIN by mail. The entire process, including our verification steps, is generally much faster than applying directly to the IRS.
Do I need an ITIN if my Stripe account is for personal use and not a business?
Generally, an ITIN is required if you have U.S. tax filing obligations or are engaged in activities that necessitate a U.S. tax ID. If your Stripe account is solely for personal transactions unrelated to U.S. business or income subject to U.S. tax, you may not need an ITIN. However, if you are receiving U.S. income that requires reporting or withholding, an ITIN is necessary.
What is the difference between an ITIN and an EIN for my Stripe account?
An ITIN (Individual Taxpayer Identification Number) is for individuals who need to file U.S. taxes but cannot get an SSN. An EIN (Employer Identification Number) is for businesses, corporations, partnerships, and other entities. If you form a U.S. LLC or corporation through Stripe Atlas or another service, you will need an EIN for the entity, and potentially an ITIN for yourself as an individual owner if you have U.S. tax obligations.
Can I apply for an ITIN if I am physically in Portugal?
Yes, you can apply for an ITIN while physically in Portugal. The application process can be completed remotely by working with a Certified Acceptance Agent (CAA) like itin.net, who can handle the verification of your documents without you needing to travel to the U.S. or mail original documents to the IRS.
Does the U.S.-Portugal tax treaty affect my need for an ITIN?
The U.S.-Portugal tax treaty may reduce or eliminate U.S. tax withholding on certain types of income you receive. However, it does not eliminate the requirement to file a U.S. tax return or obtain a U.S. tax identification number if you have U.S. source income or other U.S. tax obligations. You may need an ITIN to file your return and claim treaty benefits.
