Belgian Substack Writers Face Unique U.S. Tax Reporting Demands
As a Substack writer based in Belgium, you may encounter specific U.S. tax reporting requirements due to your income originating from U.S.-based platforms like Substack. Stripe, which often handles payouts for such platforms, is legally obligated to report payments made to non-U.S. persons to the IRS. This reporting typically requires a U.S. taxpayer identification number. For individuals who do not qualify for a Social Security Number (SSN), the Individual Taxpayer Identification Number (ITIN) serves this purpose. The primary friction point for Belgian Substack writers is often the unexpected need to obtain this U.S. tax ID to ensure compliance and avoid potential penalties or disruptions to their payment streams. Unlike U.S. residents or citizens, you are subject to U.S. tax reporting rules as a non-resident alien earning income sourced from the United States, even if you have no physical presence there. This situation necessitates a clear understanding of how to obtain the necessary documentation for U.S. tax purposes. The Belgium–U.S. tax treaty may offer some relief or specific considerations, but it does not eliminate the reporting obligation for U.S.-sourced income. Therefore, proactively addressing your U.S. tax identification needs is essential for smooth business operations.
When You Need an ITIN for Substack Income
An ITIN is generally required if you are a non-resident alien receiving U.S.-sourced income and cannot obtain an SSN. For Substack writers in Belgium, this most commonly arises when your earnings from the platform, processed via U.S. entities like Stripe, exceed certain reporting thresholds. Stripe, acting as a U.S. payer, must report these payments to the IRS. Without a U.S. taxpayer identification number, they may be required to withhold taxes at a higher rate, or your ability to receive payments could be impacted. The IRS mandates that individuals who have a U.S. tax filing obligation but no SSN must obtain an ITIN. This includes scenarios where you are earning royalties or other income from U.S. sources. While the Belgium–U.S. tax treaty exists, it primarily addresses double taxation and the application of withholding tax rates. It does not exempt you from the requirement to have a U.S. tax identification number if you are engaged in activities generating U.S. income that is subject to reporting. Therefore, if your Substack earnings are processed through a U.S. entity and reported to the IRS, obtaining an ITIN becomes a necessary step for tax compliance.
Essential Documents for Your ITIN Application
To apply for an ITIN, you must complete and submit IRS Form W-7, Application for IRS Individual Taxpayer Identification Number. This form requires detailed personal information, including your name, address, and foreign tax identification number. Alongside Form W-7, you must provide original or certified copies of supporting identification documents. The most commonly accepted primary identification document is a valid passport. If a passport is not available, other documents like a national identity card, birth certificate, or U.S. visa may be considered, but a passport is strongly preferred by the IRS. You will also need to submit a U.S. federal tax return with your Form W-7, unless you qualify for an exception. For Substack writers in Belgium, this typically means filing a Form 1040-NR (U.S. Nonresident Alien Income Tax Return) to report your Substack earnings. Ensure all documents are current and accurately reflect your legal name as it appears on your passport or other primary ID. Incomplete or mismatched documentation is a leading cause of application delays or rejections.
The ITIN Application Process and Timeline
The ITIN application process involves several key steps. First, you must complete IRS Form W-7. This form is submitted along with your U.S. federal tax return and required identification documents. You have two primary options for submitting your application: you can mail all original documents directly to the IRS, or you can apply through a Certified Acceptance Agent (CAA). Applying through a CAA, such as itin.net, allows them to verify your original identification documents and forward your application to the IRS on your behalf. This method means you do not have to mail your original passport or other vital documents, as the CAA returns them to you immediately after verification. The typical timeline for processing an ITIN application when filed through a CAA is approximately 5–10 business days from the date the IRS receives the application. If you choose to mail your documents directly to the IRS, the processing time can be significantly longer, often ranging from several weeks to a few months. The IRS will issue your ITIN via mail on a Form CP-565, which is your official ITIN notice. Following these steps diligently ensures a smoother application experience.
Common Application Errors for Belgian Substack Writers
Belgian Substack writers often encounter specific pitfalls when applying for an ITIN. A frequent mistake is failing to submit a complete and accurate U.S. tax return alongside the Form W-7. For Substack income, this means correctly filing Form 1040-NR and reporting all U.S.-sourced earnings. Another common issue is providing insufficient or invalid identification documents; always use your valid passport if possible. Some writers incorrectly claim treaty benefits without understanding the specific articles or eligibility requirements of the Belgium–U.S. tax treaty, leading to incorrect tax calculations on their return. Furthermore, attempting to mail original identification documents directly to the IRS is a significant risk, as these documents can be lost or delayed in transit, causing considerable inconvenience. Ensure your legal name is consistent across all submitted documents, including your passport and the W-7 form. Mismatched names are a primary reason for ITIN application rejections. Lastly, incomplete sections on the W-7, such as missing foreign tax identification numbers or incorrect addresses, can also lead to delays.
Benefits of Using a Certified Acceptance Agent (CAA)
Applying for an ITIN through a Certified Acceptance Agent (CAA) offers distinct advantages, particularly for individuals who are hesitant to mail sensitive original documents. As a CAA, itin.net can authenticate your identification documents, such as your passport, directly. This means you can have your original documents verified by us and returned to you on the same day, eliminating the risk of loss or delay associated with mailing them to the IRS. The CAA acts as an intermediary, reviewing your Form W-7 and supporting documentation for completeness and accuracy before forwarding it to the IRS. This pre-screening process significantly reduces the likelihood of your application being rejected due to common errors. The IRS grants CAAs the authority to accept or reject applications on their behalf, streamlining the process. For Belgian Substack writers, this expedited process, typically taking 5–10 business days once submitted to the IRS, provides peace of mind and a faster route to obtaining your ITIN. This service is invaluable for ensuring your tax compliance without unnecessary risk or prolonged waiting periods.
Next Steps After Obtaining Your ITIN
Once you receive your official ITIN from the IRS on Form CP-565, you can use it for all future U.S. tax filings and reporting requirements. For Substack writers, this means providing your ITIN to Stripe and any other U.S. payers to ensure accurate tax reporting and avoid excessive withholding. If you are considering forming a U.S. business entity, such as a U.S. LLC, an ITIN can be a stepping stone, though an EIN is typically required for business operations. You may also need your ITIN to open a U.S. bank account, which can simplify managing your U.S.-sourced income. Remember that an ITIN is for tax identification purposes only; it does not authorize you to work in the United States. If your income situation changes or you become eligible for an SSN, you should follow the appropriate procedures to update your status.

Practical tips
- Ensure your legal name on Form W-7 exactly matches your passport and any previous U.S. tax filings to prevent rejections.
- Gather a valid passport as your primary identification document; other forms of ID may cause delays or require additional scrutiny.
- File a complete U.S. tax return (Form 1040-NR) with your W-7 application, accurately reporting all Substack income, unless you qualify for a specific exception.
- Use a Certified Acceptance Agent (CAA) to verify your original documents, avoiding the need to mail them directly to the IRS and speeding up the process.
- Double-check all treaty-based positions on your tax return; incorrect claims are a common reason for IRS review and potential delays.
Frequently asked questions
As a Substack writer in Belgium, do I need an ITIN if my earnings are below $600?
While Stripe may not issue a Form 1099-NEC for earnings below $600, the IRS still requires U.S.-sourced income to be reported. If your Substack income is processed by a U.S. entity, they may still report it to the IRS, necessitating a U.S. taxpayer identification number like an ITIN, especially if you have other U.S. tax obligations. It's advisable to consult with a tax professional to confirm your specific reporting requirements.
How long does it take to get an ITIN through itin.net?
When you apply through itin.net as a Certified Acceptance Agent (CAA), your ITIN application is typically processed by the IRS within 5–10 business days after submission. This timeframe excludes the time it takes for us to verify your documents and forward your application.
Can I use my Belgian national ID card instead of a passport for my ITIN application?
While the IRS may accept other documents, a valid passport is the preferred and most commonly accepted form of identification for ITIN applications. Using a national ID card might lead to additional scrutiny or delays. It is best to use your passport if available to ensure a smoother process.
What is the difference between an ITIN and an EIN for a Substack writer?
An ITIN (Individual Taxpayer Identification Number) is for individuals filing personal U.S. taxes. An EIN (Employer Identification Number) is for businesses. As a Substack writer, you will likely need an ITIN for your personal income reporting. An EIN becomes relevant if you decide to establish a U.S. business entity, like a U.S. LLC, which would then need its own tax identification number.
Does the Belgium–U.S. tax treaty affect my need for an ITIN?
The Belgium–U.S. tax treaty primarily addresses double taxation and may influence withholding tax rates on certain types of income. However, it does not eliminate the requirement for a U.S. taxpayer identification number if you are earning income sourced from the U.S. that is subject to reporting by platforms like Substack or payment processors like Stripe.
What happens if I don't get an ITIN for my Substack income?
If your Substack income is subject to U.S. reporting requirements and you do not have an ITIN, the paying agent (e.g., Stripe) may be required to withhold taxes at a higher rate, typically 30%. This can significantly reduce your net earnings. Additionally, failure to comply with U.S. tax reporting obligations could lead to penalties from the IRS.
