Why Belgian Substack Writers Need a U.S. EIN
Substack writers based in Belgium encounter a specific tax reporting requirement when their earnings reach certain thresholds, necessitating a U.S. Employer Identification Number (EIN). While Substack itself is a U.S.-based platform, Belgian tax residents are subject to Belgian income tax laws. However, the U.S. platform's payout mechanisms, often involving U.S. financial institutions or payment processors like Stripe, trigger U.S. tax reporting obligations. Without a U.S. EIN, these platforms may default to higher withholding rates on your earnings, or they may be unable to process payouts efficiently. This situation creates a friction point for Belgian creators who are otherwise compliant with their local tax obligations. The U.S. requires non-resident entities and individuals receiving certain types of U.S.-sourced income or engaging in U.S. business activities to obtain an EIN. For Substack writers, this typically arises from the platform's need to report payments made to them to the U.S. Internal Revenue Service (IRS). Understanding this U.S. requirement is key to avoiding unnecessary tax complications and ensuring smooth financial operations for your Substack business.
When an EIN Becomes Necessary for Belgian Substack Writers
An EIN is generally required for Substack writers in Belgium when they begin receiving payouts through U.S.-based payment processors or when their U.S.-sourced income reaches a level that triggers reporting requirements. The primary trigger is often the payout system itself. Platforms like Substack, which operate through U.S. entities, are obligated by the IRS to report payments made to independent contractors and businesses. If you are operating as a sole proprietor without a U.S. business entity, you might still need an EIN to properly identify yourself for tax purposes to the IRS and the payment processor. This is particularly true if you are earning beyond the threshold for casual income reporting. Furthermore, if you plan to establish a U.S. business entity, such as a U.S. LLC, to manage your Substack operations, an EIN is mandatory from the outset. This entity would need its own EIN for tax filings and for opening a U.S. bank account, which is often a subsequent step for non-resident business owners. The U.S. tax code aims to track income and payments, and an EIN serves as the primary identifier for businesses and non-individuals engaging with the U.S. financial system, even if you are physically located outside the U.S. Confirming the specific payout thresholds and reporting requirements with your payment processor or a tax professional is advisable.
Required Documentation for EIN Application
Applying for an EIN as a non-resident Belgian writer involves specific documentation to verify your identity and the legitimacy of your application. The primary form is the IRS Form SS-4, Application for Employer Identification Number. As a non-resident without a U.S. Social Security Number (SSN) or Individual Taxpayer Identification Number (ITIN), you will need to indicate this on the form. Specifically, on line 7b of Form SS-4, where it asks for an SSN, ITIN, or EIN, you should write 'Foreign'. This clearly communicates your status to the IRS. The responsible party applying for the EIN must provide identification. For individuals, this typically means a copy of a valid passport. Your passport serves as proof of identity and nationality. Additionally, if you are forming a U.S. business entity, such as a U.S. LLC, you will need to provide the relevant formation documents. These documents vary by state but generally include articles of incorporation or organization. If you are operating as a sole proprietor without a formal entity, you may not need formation documents, but you will still need to clearly state your business activity. It's essential that all information on Form SS-4 aligns with your identification documents. Mismatched names or addresses can lead to application delays or rejections. A U.S. business address or a mail forwarding service address is also typically required on the application. This does not mean you need a physical office in the U.S., but rather a reliable mailing address for IRS correspondence.
The EIN Application Process and Timeline for Non-Residents
The process for obtaining an EIN differs significantly for U.S. residents versus non-residents. For Belgian Substack writers, the application must be submitted without an SSN or ITIN. Non-residents cannot use the IRS's online portal, which is designed for those with an SSN or ITIN. Instead, the application is typically submitted via fax or mail. The IRS Form SS-4 is completed with all required information, including the designation of 'Foreign' on line 7b. Once completed, you will fax or mail the form to the IRS. The typical processing time for non-residents via fax or mail is considerably longer than for U.S. residents. You can expect a processing window of approximately 3 to 5 weeks. This timeframe accounts for international mail or fax transmission and manual processing by the IRS. It is crucial to factor this extended timeline into your business planning to avoid any disruptions in receiving payouts or fulfilling other business requirements. The IRS will mail the EIN confirmation, often on an IRS letterhead, to the address provided on Form SS-4. This confirmation document is vital for subsequent steps, such as opening a U.S. bank account. Patience and accuracy are key throughout this process, as any errors can further extend the processing time.
Common Mistakes for Belgian Substack Writers Applying for an EIN
Belgian Substack writers often face specific pitfalls when applying for an EIN that differ from common U.S. applicant errors. A frequent mistake is attempting to use the online application portal, which is only available to individuals with an SSN or ITIN. Non-residents must use the fax or mail method. Another common error on Form SS-4 is incorrectly filling out line 7b. Instead of leaving it blank or entering 'N/A', you must write 'Foreign' to indicate the absence of a U.S. tax ID. Failing to do so can lead to the application being rejected. Some writers mistakenly believe they need to establish a U.S. LLC before applying for an EIN. While forming a U.S. LLC is a common step, it's not always a prerequisite for obtaining an EIN if you are operating as a sole proprietor receiving income from Substack. The type of entity you select on Form SS-4 must accurately reflect your business structure. Misrepresenting your entity type can cause significant tax complications later. Finally, ensure that the business address provided is a valid mailing address where you can receive IRS correspondence. Using an invalid or non-deliverable address will impede communication with the IRS and delay the issuance of your EIN. Double-checking all fields against your identification documents is critical.
The Certified Acceptance Agent (CAA) Path for EIN Applications
For non-residents seeking an EIN, the traditional fax or mail application process can be lengthy. A more efficient alternative is to work with a Certified Acceptance Agent (CAA). A CAA is an individual or entity authorized by the IRS to assist non-residents in obtaining an EIN. Services like itin.net act as CAAs. When you apply for an EIN through a CAA, they act as an intermediary between you and the IRS. The CAA will review your completed Form SS-4 for accuracy and completeness, ensuring all fields are correctly filled out, especially for non-residents. They can then transmit the application directly to the IRS via their dedicated channels. This significantly speeds up the process. While the IRS still has internal processing times, using a CAA typically reduces the overall waiting period compared to the standard fax or mail method. For instance, working with a CAA can often shorten the EIN issuance time to a matter of days rather than weeks. They also provide a layer of assurance that your application meets IRS requirements, minimizing the risk of rejection due to common errors. This streamlined approach is particularly beneficial for Substack writers who need their EIN promptly to manage their business finances and comply with payment processor requirements. Itin.net offers this expedited service, providing a faster route to obtaining your essential U.S. tax ID.
Next Steps After Obtaining Your EIN
Once you have successfully obtained your U.S. EIN, several practical steps follow to fully leverage it for your Substack business. The most immediate next step is often opening a U.S. bank account. Many U.S. banks and financial technology companies require an EIN and business formation documents (if applicable) to open an account for non-residents. This U.S. bank account is crucial for separating your business finances from personal ones and for facilitating smoother transactions with platforms like Substack and other potential U.S.-based clients or partners. You will also need to update your payment information with Substack or your payment processor, providing them with your new EIN. This ensures accurate tax reporting and avoids potential issues with payouts. If you formed a U.S. LLC, you will need to ensure you are compliant with your state's filing requirements, which may include annual reports and franchise taxes. Furthermore, depending on your income and the specific provisions of the Belgium–U.S. tax treaty, you may have ongoing U.S. tax filing obligations. This could include filing forms like Form 1040-NR (U.S. Nonresident Alien Income Tax Return) or Form 5472 (Information Return of a 21% Foreign-Owned U.S. Corporation or a Foreign Corporation Engaged in a U.S. Trade or Business) if you have a U.S. entity. Reviewing your specific tax situation with a qualified tax professional specializing in U.S. non-resident taxation is highly recommended.

Practical tips
- Use the exact same legal name for yourself and any U.S. entity across all IRS forms, your passport, and business formation documents. Mismatched name fields are a primary reason for EIN application rejection.
- When filling out Form SS-4, line 7b, enter 'Foreign' if you do not have an SSN or ITIN. Do not leave this field blank or write 'N/A'.
- Ensure the U.S. business address provided on Form SS-4 is a valid mailing address where you can reliably receive IRS correspondence. A mail forwarding service can be used if you do not have a physical U.S. presence.
- If you are forming a U.S. LLC, ensure its formation documents are finalized and approved by the state before submitting your EIN application. The IRS requires proof of entity existence.
- Understand that the Belgium–U.S. tax treaty may affect your U.S. tax obligations. Consult with a tax professional experienced in international taxation to determine any potential benefits or filing requirements.
Frequently asked questions
Can I use my Belgian national ID number instead of an SSN or ITIN for the EIN application?
No, you cannot use your Belgian national ID number. The IRS Form SS-4 specifically requests a U.S. Social Security Number (SSN) or Individual Taxpayer Identification Number (ITIN). As a non-resident without either, you must write 'Foreign' on line 7b of Form SS-4.
How long does it take to get an EIN as a Belgian resident?
For non-residents applying via fax or mail directly to the IRS, the typical processing time is 3 to 5 weeks. If you use a Certified Acceptance Agent (CAA) like itin.net, the process can be significantly faster, often taking only a few business days.
Do I need to form a U.S. LLC before applying for an EIN?
Not necessarily. If you are operating as a sole proprietor and receiving income from Substack, you can apply for an EIN as an individual without forming a U.S. LLC. However, if you plan to establish a U.S. LLC, you will need the formation documents to apply for the EIN for that entity. Many non-residents choose to form a U.S. LLC for liability protection and easier business operations.
What is the difference between an EIN and an ITIN for a Belgian writer?
An EIN (Employer Identification Number) is a federal tax ID for businesses and other entities, used for tax reporting and opening business accounts. An ITIN (Individual Taxpayer Identification Number) is for individuals who need a U.S. tax ID but do not have and are not eligible for an SSN. As a Substack writer receiving business income, you will typically need an EIN for your business operations, not an ITIN for yourself personally, unless you have separate personal U.S. tax filing requirements.
Can I open a U.S. bank account with just my EIN?
An EIN is a critical requirement for opening a U.S. bank account as a non-resident, but it's usually not the only document needed. Most U.S. banks will also require identification for the account signatories (like a passport), and if you formed a U.S. entity, you'll need its formation documents and potentially an Operating Agreement. Some fintech platforms like Mercury or Relay may have streamlined processes.
Will I have to pay U.S. income tax if I have an EIN?
Having an EIN does not automatically mean you owe U.S. income tax. Your U.S. tax liability depends on the nature and source of your income, and your residency status. The Belgium–U.S. tax treaty may also reduce or eliminate certain U.S. tax obligations. However, you may still have reporting requirements, such as filing Form 5472 if you have a U.S. entity. It is essential to consult with a tax professional.
