Why Substack Writers in Mongolia Need an ITIN
Substack writers in Mongolia face a specific tax reporting challenge due to U.S. platform payouts. When you receive payments from U.S.-based platforms like Substack, particularly through payment processors such as Stripe, the IRS requires proper tax identification. For individuals who are not U.S. citizens or permanent residents and therefore cannot obtain a Social Security Number (SSN), the alternative is an Individual Taxpayer Identification Number (ITIN). This 9-digit number is issued by the IRS solely for tax purposes. Without an ITIN, U.S. payers may be required to withhold taxes at a higher rate, impacting your net earnings. Furthermore, accurate tax reporting is essential for maintaining compliance with U.S. tax law, even if you are based thousands of miles away in Mongolia. The ITIN serves as your unique identifier for filing U.S. tax returns, such as the Form 1040-NR for non-resident aliens.
The situation for Substack writers in Mongolia is distinct because of the lack of a U.S. income tax treaty. Unlike individuals in countries with such treaties, you cannot claim reduced withholding rates based on treaty provisions for most types of income. This means that a correctly obtained ITIN is even more critical for ensuring your U.S. tax obligations are met without unnecessary withholdings. Failing to secure an ITIN when required can lead to significant complications, including back taxes, penalties, and interest. It is therefore essential to understand the process and ensure your application is accurate from the outset.
When You Need an ITIN
An ITIN is required for Substack writers in Mongolia when U.S. tax reporting obligations arise from your earnings. The primary trigger is receiving payments from a U.S. entity, such as Substack, which uses U.S. payment processors. These processors, like Stripe, are obligated to report payments made to non-U.S. individuals to the IRS. To do this reporting correctly, they need a U.S. taxpayer identification number. If you do not have an SSN, the IRS provides the ITIN for this purpose.
You will typically need an ITIN if you are required to file a U.S. tax return but cannot get an SSN. This often includes scenarios where you are an independent contractor or freelancer earning income sourced from the United States. For Substack writers, this income is generally considered U.S.-sourced. Even if you believe your tax liability is zero due to foreign earned income exclusions or other factors, you might still need to file a U.S. tax return and thus require an ITIN. The IRS may also request that you obtain an ITIN for other tax-related matters, such as claiming treaty benefits (though this is not applicable to Mongolia) or filing specific informational returns. In the absence of a U.S. income tax treaty, the need for an ITIN is primarily driven by the reporting requirements of U.S. payers and your obligation to file U.S. tax returns for U.S.-sourced income.
Required Documents for ITIN Application
Applying for an ITIN involves submitting Form W-7, Application for IRS Individual Taxpayer Identification Number, along with original or certified copies of required identification documents and proof of foreign status. The most commonly accepted identification document is a valid passport. Your passport serves as both proof of identity and nationality. If you do not have a passport, other documents may be accepted, but a passport is strongly preferred by the IRS for expedited processing.
In addition to your passport, you must include supporting documentation that substantiates your reason for needing an ITIN. For most Substack writers, this means demonstrating that you have a U.S. tax filing requirement. This could involve providing a U.S. tax return, such as a Form 1040-NR, that you intend to file. If you are applying for an ITIN solely to meet a payer's requirement and are not yet filing a tax return, you will need to provide documentation explaining this situation. Foreign birth certificates, national identification cards, and U.S. visas (if applicable) can serve as supplementary identification. Ensure all documents submitted are valid and have not expired. Any documents not in English must be accompanied by a certified English translation.
The ITIN Application Process
The ITIN application process begins with accurately completing Form W-7. This form requires personal information, including your name, address, date of birth, and foreign tax identification number (if applicable). It also requires you to state the reason for applying for an ITIN. For Substack writers in Mongolia, the reason is typically to comply with U.S. tax reporting requirements for income earned from U.S. platforms.
Once Form W-7 is complete, you must gather your supporting documentation. As mentioned, this usually includes your original or certified copy of a valid passport and any other required identification. You can then choose how to submit your application. The IRS offers several methods, including mail, through a Certified Acceptance Agent (CAA), or at certain IRS Taxpayer Assistance Centers (TACs). Using a CAA, like itin.net, is generally recommended as they can verify your original documents and forward your application to the IRS, significantly reducing the risk of losing your vital identification papers. The typical processing timeline for an ITIN application submitted through a CAA is 5–10 business days. Applications sent directly to the IRS may take longer, potentially several weeks or even months, depending on IRS workload. You will receive a CP-565 notice from the IRS once your ITIN has been assigned.
Common Mistakes for Substack Writers in Mongolia
Substack writers in Mongolia often make specific errors when applying for an ITIN, primarily stemming from a lack of familiarity with U.S. tax procedures and documentation requirements. A frequent mistake is failing to include a complete and accurate U.S. tax return with the Form W-7 application, or an explanation of why one is not being filed. Many writers in your situation may not realize they need to file a Form 1040-NR even if their U.S. tax liability is minimal or zero. The IRS requires proof of a filing requirement.
Another common pitfall is submitting photocopies of identification documents instead of originals or certified copies. The IRS will not accept photocopies for identity verification. Mailing original documents directly to the IRS carries the risk of loss or damage, which can be a significant setback. Using a Certified Acceptance Agent helps mitigate this risk by verifying your documents on your behalf. Incorrectly claiming treaty benefits is another error, though not applicable to Mongolia due to the absence of a U.S. income tax treaty. Ensure you do not attempt to claim treaty benefits if no treaty exists between the U.S. and your country of residence. Lastly, mismatched names across your identification documents and the W-7 form can cause delays or rejections. Ensure your name is consistent across all submitted paperwork.
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 not physically present in the United States. As a designated agent of the IRS, a CAA can authenticate your original identification documents, such as your passport, and your application for the ITIN. This means you do not have to mail your valuable original documents directly to the IRS, which significantly reduces the risk of them being lost or stolen in transit.
When you use a CAA like itin.net, the agent reviews your Form W-7 and supporting documents for completeness and accuracy before submitting them to the IRS on your behalf. This pre-screening process helps to catch common errors that might otherwise lead to delays or rejections. The typical processing timeline when using a CAA is considerably faster, often 5–10 business days, compared to the much longer wait times when mailing documents directly to the IRS. This efficiency is crucial for Substack writers who need their ITIN promptly to ensure correct tax withholding and compliance with platform requirements. The CAA service streamlines the process and provides expert guidance, making it a more secure and efficient option for international applicants.
Next Steps After ITIN Application
Once your ITIN application is approved, the IRS will mail you a CP-575 notice, which contains your assigned ITIN. You should then update your tax information with platforms like Substack and your payment processor, such as Stripe, using your new ITIN. This ensures that all future tax reporting is accurate and that any applicable withholding taxes are calculated correctly. If you are required to file a U.S. tax return for the year you applied, you will use this ITIN on your Form 1040-NR.
For Substack writers in Mongolia, securing your ITIN is a critical step in managing your U.S. tax obligations. It facilitates compliance and helps you avoid higher withholding rates. If you anticipate ongoing U.S. income or plan to expand your online presence, consider consulting with a tax professional to ensure you are meeting all your tax responsibilities.

Frequently asked questions
Can I get an ITIN if I live in Mongolia and only earn money from Substack?

How long does it take to get an ITIN from Mongolia?
When applying through a Certified Acceptance Agent (CAA) like itin.net, the process typically takes 5–10 business days. Applying directly to the IRS can take significantly longer, potentially several weeks to months.
What documents do I need to send to the IRS from Mongolia for an ITIN?
You need to submit Form W-7, proof of your identity and foreign status (a valid passport is preferred), and documentation showing your U.S. tax filing requirement. A CAA can verify your original documents, so you don't have to mail them.
Do I need to file a U.S. tax return to get an ITIN for my Substack income?
Generally, yes. You need to demonstrate a U.S. tax filing requirement. This often means filing a U.S. tax return, such as Form 1040-NR, along with your Form W-7 application. If you cannot file immediately, you must provide a valid explanation.
What happens if Stripe or Substack withholds taxes from my payments before I get an ITIN?
If U.S. payers are required to withhold taxes and you don't have an ITIN, they may use a higher backup withholding rate. Once you obtain your ITIN and file your U.S. tax return, you can claim any overpaid taxes as a refund or apply them to your tax liability.
Is there a U.S. tax treaty between Mongolia and the U.S. that affects my ITIN application?
No, there is currently no U.S. income tax treaty between Mongolia and the United States. This means you cannot claim reduced withholding rates based on treaty provisions for most types of income.
