Substack Writers in Brunei Face Unique ITIN Requirements
Substack writers based in Brunei encounter specific challenges when needing an ITIN. Unlike U.S. residents or citizens, non-residents often require this number to comply with U.S. tax obligations stemming from income earned through U.S.-based platforms like Substack. The primary trigger is Stripe, the payment processor commonly used by Substack, which reports payments made to non-U.S. persons to the IRS. Without proper documentation, including an ITIN or an Employer Identification Number (EIN), Stripe may be required to withhold a portion of your earnings. This scenario is particularly relevant for Brunei-based writers who may not have a Social Security Number (SSN) and are thus ineligible for one. The need for an ITIN arises from U.S. tax law, which requires reporting of income, even for foreign individuals, if that income originates from U.S. sources. For Substack writers, this income is typically derived from U.S. subscribers or the U.S. platform itself. Therefore, obtaining an ITIN becomes a necessary step to ensure compliance and avoid potential tax withholding on your earnings. It is important to understand that an ITIN is solely for tax reporting purposes and does not grant work authorization in the U.S. or eligibility for Social Security benefits.
When You Need an ITIN as a Substack Writer from Brunei
An ITIN is required for Substack writers from Brunei primarily when your earnings reach certain thresholds reported by payment processors to the U.S. Internal Revenue Service (IRS). Stripe, a common platform for distributing Substack earnings, is obligated to report these payments. If you are a non-U.S. person without an SSN, you may be subject to backup withholding at a rate of 24% on your U.S. source income. To avoid this, you need to provide Stripe with a valid U.S. taxpayer identification number, which for individuals is typically an ITIN. This is often communicated through IRS Forms W-8BEN or W-8BEN-E, which allow you to claim foreign status and potentially treaty benefits. However, Brunei does not have an income tax treaty with the U.S., meaning you cannot claim reduced withholding rates based on a treaty. Therefore, the most straightforward way to comply and avoid backup withholding is to obtain an ITIN. This allows you to file a U.S. tax return, typically Form 1040-NR (U.S. Nonresident Alien Income Tax Return), and report your Substack income accurately. Failing to obtain an ITIN when required can lead to significant portions of your income being withheld, impacting your cash flow and financial planning. It is also important to note that while an EIN is generally for business entities, it is not typically used by individual freelance writers unless they have established a U.S. business entity, such as a U.S. LLC.
Essential Documents for Your ITIN Application
To apply for an ITIN, you must submit Form W-7, Application for IRS Individual Taxpayer Identification Number. This form requires accurate personal information, including your full legal name, foreign address, and U.S. taxpayer identification number (which you are applying for). Crucially, you must submit this form along with your U.S. federal income tax return for the year you are claiming the ITIN for, unless you qualify for an exception. For Substack writers in Brunei, the most common supporting document to verify your identity and foreign status is a valid passport. Your passport should be current and contain your full legal name, date of birth, and photograph. If you do not have a passport, other identification documents may be accepted, but a passport is strongly preferred by the IRS. Additional documentation might include a birth certificate or national identification card, but these are secondary to a passport. Ensure that the name on your Form W-7 exactly matches the name on your identification documents to avoid delays or rejections. Any discrepancies can lead to the IRS requesting further information, prolonging the application process. The IRS also requires proof of your foreign status, which your passport serves to confirm. If you have a U.S. visa, it can also be submitted as supporting documentation, although it is not strictly required if you have a valid passport. Submitting a complete and accurate Form W-7 with the correct supporting documents is key to a successful ITIN application.
The ITIN Application Process and Timeline
The process for obtaining an ITIN involves several steps, starting with completing Form W-7. You must attach your original, certified, or notarized identification documents, along with your U.S. federal income tax return. The tax return is a mandatory component unless you qualify for one of the specific exceptions listed in the Form W-7 instructions, such as applying for an ITIN to claim treaty benefits or to comply with withholding requirements. For most Substack writers in Brunei, this means filing a U.S. tax return, such as Form 1040-NR, to report your Substack income. Once your application is prepared, you have two primary options for submission: mailing it directly to the IRS or applying through a Certified Acceptance Agent (CAA). Mailing directly to the IRS can result in longer processing times, as they need to verify your original documents. The IRS processing time for direct mail applications can range from 7 to 14 weeks. Alternatively, applying through a Certified Acceptance Agent (CAA), like itin.net, offers a streamlined process. A CAA can verify your original identification documents on your behalf, meaning you do not have to mail them to the IRS. This significantly speeds up the process, with ITINs typically issued within 5–10 business days after the IRS receives the application from the CAA. The IRS will then issue you an ITIN, which will be mailed to the address provided on your Form W-7. You will also receive a tax form document, such as a CP-565, confirming your ITIN. It is essential to keep this document safe, as it contains your unique ITIN.
Common Pitfalls for Brunei Substack Writers
Substack writers in Brunei often encounter specific pitfalls when applying for an ITIN. A frequent issue is the misunderstanding of withholding requirements. Because Brunei has no income tax treaty with the U.S., writers might incorrectly assume they can claim treaty benefits on their Form W-7 or tax return. This can lead to an application being rejected or an incorrect tax filing. Another common mistake is failing to include a complete U.S. federal income tax return with the Form W-7. The IRS requires this unless a specific exception applies. For example, simply earning income from Substack via Stripe necessitates filing a tax return to claim the ITIN, unless you are using the ITIN for specific withholding certificate purposes not applicable here. Mismatched names between your identification documents (like your passport) and your Form W-7 are also a major cause for rejection. Ensure your legal name is identical across all documents. Furthermore, many writers attempt to submit photocopies of their identification instead of original documents or certified copies. The IRS is very strict about document verification. When applying through a Certified Acceptance Agent (CAA), they will verify your original documents, eliminating the need to mail them to the IRS, thus mitigating this risk. Finally, some writers may not understand that an ITIN is for tax reporting purposes only and does not grant any immigration benefits or work authorization in the U.S.
The Certified Acceptance Agent (CAA) Advantage
Applying for an ITIN through a Certified Acceptance Agent (CAA), such as itin.net, offers significant advantages for Substack writers in Brunei. The most critical benefit is that a CAA can verify your original identification documents, such as your passport. This means you do not have to mail your irreplaceable original documents to the IRS, thereby reducing the risk of them being lost or stolen during transit. The IRS entrusts CAAs with this verification process, allowing them to certify that your documents are authentic. This verification step is crucial because the IRS requires proof of identity and foreign status to issue an ITIN. By using a CAA, you can typically have your ITIN processed much faster. While direct applications to the IRS can take several weeks or even months, applications submitted through a CAA are generally processed within 5–10 business days from the date the IRS receives the package. This accelerated timeline is invaluable for writers who need to provide a U.S. taxpayer identification number to payment processors like Stripe to avoid backup withholding. Furthermore, CAAs are trained by the IRS and are knowledgeable about the ITIN application process and common errors. They can help ensure your Form W-7 and supporting documentation are correctly completed, increasing the likelihood of a smooth and successful application. The service provided by itin.net includes guidance through the entire process, making it less daunting for individuals unfamiliar with U.S. tax procedures.
Next Steps After Obtaining Your ITIN
Once you receive your ITIN from the IRS, typically via mail as a CP-565 document, your primary tax reporting obligations are addressed. You should immediately provide this ITIN to Stripe, your payment processor for Substack earnings. This action is crucial to prevent or stop the 24% backup withholding on your future payments. Ensure you update your tax information on the Stripe portal with your new ITIN. If you have already had funds withheld due to not having an ITIN, you may be able to claim these withheld amounts as a credit when you file your U.S. federal income tax return. Filing this return is usually a requirement for obtaining the ITIN in the first place, so ensure you have completed it accurately. For Substack writers in Brunei, understanding ongoing U.S. tax obligations is important. Even if you only have U.S. source income from your newsletter, you may need to file a U.S. tax return annually. If your income situation changes or you start earning income from other U.S. sources, you may need to re-evaluate your tax filings. If you are considering expanding your U.S. business activities or need to form a U.S. entity like a U.S. LLC, you would typically need an EIN.

Practical tips
- Use your full legal name exactly as it appears on your passport for Form W-7 and any supporting documents. Any discrepancies can cause significant delays or rejection.
- Ensure your passport is valid and not expired. If your passport is expired, obtain a new one before applying for your ITIN to avoid identity verification issues.
- Include a completed U.S. federal income tax return with your Form W-7 unless you qualify for a specific exception. For Substack income, this typically means filing Form 1040-NR.
- When applying through a Certified Acceptance Agent (CAA), provide them with original or certified copies of your identification documents. They will verify these documents, so you don't have to mail originals to the IRS.
- Update your tax information with Stripe immediately after receiving your ITIN to prevent backup withholding on your Substack earnings.
Frequently asked questions
Do I need an ITIN if I only write for Substack from Brunei?
You likely need an ITIN if your Substack earnings are processed through a U.S. platform like Stripe, which reports payments to the IRS. Without an ITIN or EIN, Stripe may be required to withhold 24% of your earnings. An ITIN allows you to file a U.S. tax return and avoid this withholding.
How long does it take to get an ITIN for a Substack writer in Brunei?
Applying through a Certified Acceptance Agent (CAA) typically takes 5–10 business days for the IRS to process after submission. Mailing directly to the IRS can take 7–14 weeks. The CAA process is significantly faster.
Can I use my Brunei national ID instead of a passport for my ITIN application?
A valid passport is the preferred identification document for an ITIN application. While other documents may be accepted, a passport is the strongest form of verification for identity and foreign status. Check the IRS Form W-7 instructions for a full list of acceptable alternative documents.
What is the cost to get an ITIN?
The IRS does not charge a fee for the ITIN itself. However, if you use a Certified Acceptance Agent (CAA) service like itin.net, there is a service fee. Our Standard Package for ITIN applications is $497.
Do I need an ITIN if I already have an EIN for my business?
An EIN is for business entities, while an ITIN is for individuals. If you are earning income as an individual Substack writer, you need an ITIN. If you have established a separate U.S. business entity (like a U.S. LLC) that receives the Substack payments, then an EIN might be appropriate, but individual earnings typically require an ITIN.
What happens if I don't get an ITIN for my Substack income?
If you don't provide a U.S. taxpayer identification number (like an ITIN) to your payment processor (e.g., Stripe), they are required by the IRS to withhold 24% of your U.S. source income as backup withholding. You may also face penalties for failure to file U.S. taxes if required.
