Substack Writers in Azerbaijan Face a Specific Payment Hurdle
Substack writers in Azerbaijan often encounter a roadblock when their earnings reach a certain threshold or when they opt for direct Stripe payouts: the need for a U.S. Individual Taxpayer Identification Number (ITIN).
Unlike U.S. citizens or residents who use a Social Security Number (SSN), non-residents earning income from U.S. platforms like Substack, and processed through U.S. payment systems like Stripe, are typically required to provide an ITIN for accurate tax reporting to the IRS. This is not just a formality; it's a compliance requirement that ensures U.S. tax obligations related to that income are met.
For writers in Azerbaijan, this creates a unique challenge. You are operating a business remotely, earning income from a U.S.-based platform, and receiving payments via a U.S. financial infrastructure. The U.S. tax system requires a unique identifier for these transactions, and without an SSN, the ITIN becomes that essential identifier. Failure to provide it can lead to backup withholding at a higher rate (typically 24% on gross earnings) by the payment processor, significantly impacting your net income.
ITIN is Required for U.S. Income Reporting via Stripe
Your ITIN becomes mandatory when platforms like Substack, using payment processors like Stripe, need to report your earnings to the IRS. This reporting is generally triggered when you reach certain payment thresholds or when you are an independent contractor receiving payments from a U.S. entity.
Stripe, as a U.S.-based payment processor, is obligated by the IRS to collect tax information from its users, particularly those who are not U.S. persons. For non-U.S. individuals earning U.S.-sourced income, this means providing either an SSN or an ITIN. If you do not have an SSN, obtaining an ITIN is the standard procedure to avoid higher backup withholding rates and to comply with U.S. tax laws.
The primary trigger is the need for a U.S. taxpayer identification number. Without one, Stripe will likely implement backup withholding, deducting a significant portion of your earnings until you provide a valid ITIN or SSN. This is a standard procedure for U.S. financial institutions dealing with foreign earners and is not specific to Substack or Azerbaijan, but it directly affects your payment flow.
Essential Documents for Your ITIN Application
Applying for an ITIN requires specific documentation to verify your identity and foreign status. The primary form is the Form W-7, Application for IRS Individual Taxpayer Identification Number. This form collects your personal information and the reason for your application.
Alongside the Form W-7, you must submit original or certified copies of supporting documents. The most commonly accepted and preferred document for proving identity is your valid passport. If you do not have a passport, other documents like a national identity card, birth certificate, or driver's license may be accepted, but a passport is the most straightforward option.
In addition to a photo ID, you generally need to provide documentation that supports your need for an ITIN. For Substack writers, this often involves demonstrating a U.S. tax filing requirement. This could include a copy of a U.S. tax return you are filing concurrently, or other documentation showing U.S. income. The IRS also requires proof of your foreign status, which your passport typically fulfills. Ensure all documents are current and accurately reflect your legal name.
The ITIN Application Process: Step-by-Step
Obtaining an ITIN involves several key steps. First, you must accurately complete Form W-7. This form requires details such as your name, foreign address, and the reason you need an ITIN. For Substack writers, the reason is typically 'Non-resident alien receiving U.S. income' or similar, often tied to filing a U.S. tax return (like Form 1040-NR) or meeting IRS reporting requirements.
Next, gather your supporting documentation. This includes your original or certified copy of a valid passport and any other documents required by the IRS to prove your identity and foreign status. You will also need to include a U.S. federal income tax return, unless you qualify for an exception. For many Substack writers, filing the tax return concurrently with the Form W-7 is the most common path.
Once completed, you can submit your application. There are three main ways to do this: mail the entire package directly to the IRS in Austin, Texas; use the services of a Taxpayer Assistance Center (TAC) at select IRS offices (rarely available outside the U.S.); or apply through a Certified Acceptance Agent (CAA). The CAA route is generally the fastest and most secure. A CAA, like itin.net, reviews your application and documents, verifies their authenticity, and forwards everything to the IRS on your behalf. This process typically takes 5–10 business days for the IRS to issue the ITIN once they receive a complete application from a CAA.
Common Mistakes for Substack Writers in Azerbaijan
Substack writers in Azerbaijan often make specific errors when applying for an ITIN, primarily due to the remote nature of their work and unfamiliarity with U.S. tax procedures. One frequent mistake is failing to include a U.S. tax return with the Form W-7, unless an exception applies. Many assume the ITIN is solely for payment processing, not for tax filing compliance.
Another common pitfall is mismatched names. If your name on the Form W-7 does not exactly match your name on your passport or other identification documents, the IRS will likely reject your application. This includes variations in spelling, middle names, or inclusion/exclusion of suffixes like 'Jr.' or 'III'.
Furthermore, applicants sometimes mail original identification documents directly to the IRS, risking loss or theft. Using a Certified Acceptance Agent (CAA) prevents this, as they verify your original documents and return them to you immediately. Lastly, incorrect treaty claims can lead to denial if you are attempting to claim benefits under a U.S. tax treaty without meeting the specific criteria, which is less common for simple Substack income but possible if other U.S. income sources are involved. The former USSR–U.S. tax treaty may apply in certain circumstances, but its application to digital services income requires careful review.
The Certified Acceptance Agent (CAA) Advantage
Applying for an ITIN through a Certified Acceptance Agent (CAA) offers significant advantages, especially for individuals in Azerbaijan. A CAA is an official third-party agent authorized by the IRS to help applicants obtain ITINs. This means they can review your application, verify your original identification documents, and forward your complete package to the IRS on your behalf.
The most critical benefit of using a CAA is that you do not have to mail your original identification documents, such as your passport, to the IRS. The CAA will review and authenticate these originals and return them to you immediately. This significantly reduces the risk of loss or theft of vital personal documents during transit.
Furthermore, CAAs are trained to ensure your Form W-7 and supporting documents are complete and accurate, minimizing the chances of application rejection. This can expedite the process, as the IRS typically processes applications submitted by a CAA more quickly, often within 5–10 business days of receiving them. For Substack writers in Azerbaijan, this means a faster path to obtaining the necessary ITIN to avoid backup withholding and ensure smooth payment processing.
Next Steps After ITIN Application
Once the IRS approves your ITIN application, you will receive an ITIN assignment letter, typically a CP-575 notice. This letter confirms your unique 9-digit ITIN. You should keep this document in a secure place, as it is your official record of your ITIN.
With your ITIN secured, you can now provide it to Substack and Stripe. This will update your tax information, allowing for correct reporting to the IRS and preventing backup withholding on your future earnings. Ensure you update your information on both platforms promptly to avoid any further interruptions or deductions.
For Substack writers in Azerbaijan, having an ITIN is often the first step in managing U.S. tax obligations. Depending on your overall financial situation and income sources, you might also need to consider other U.S. tax forms or filings. If you are establishing a U.S. business entity, such as a U.S. LLC, you might need an EIN. You can learn more about ITIN applications and services at itin.net.

Practical tips
- Ensure the legal name on your Form W-7 precisely matches your passport and any other identification documents submitted to avoid common rejection reasons.
- When applying through a Certified Acceptance Agent (CAA), you will not need to mail original identification documents to the IRS, mitigating risks of loss or theft.

- Understand the former USSR–U.S. tax treaty's potential implications for your income, although simple Substack earnings may not directly benefit from treaty provisions without further analysis.
- Keep a secure record of your ITIN once issued, as it is a crucial identifier for all future U.S. tax-related activities and income reporting.
Frequently asked questions
Do I need an ITIN if I am a Substack writer in Azerbaijan and only receive payments via PayPal?
If PayPal is processing your payments and is a U.S.-based entity, they may also require a U.S. taxpayer identification number, similar to Stripe. You should check PayPal's specific requirements for non-U.S. persons receiving U.S. income. Generally, any U.S. platform or payment processor distributing U.S.-sourced income will need a U.S. tax ID like an ITIN.
How long does it take to get an ITIN if I apply through a Certified Acceptance Agent?
When applying through a Certified Acceptance Agent (CAA), the IRS typically processes the application and issues an ITIN within 5–10 business days after receiving the complete application package. The CAA's verification process also speeds up submission to the IRS.
Can I use my Azerbaijani passport to apply for an ITIN?
Yes, a valid Azerbaijani passport is an acceptable form of identification for your ITIN application. It serves as both proof of identity and proof of foreign status, which are required by the IRS.
What happens if I don't get an ITIN and continue earning from Substack?
If you do not provide a U.S. taxpayer identification number (like an ITIN) to your payment processor (e.g., Stripe), they will likely implement backup withholding. This means a significant percentage of your earnings, typically 24% of the gross amount, will be withheld and sent to the IRS until you provide the required documentation.
Do I need to file a U.S. tax return to get an ITIN?
For most applicants, including Substack writers earning U.S. income, filing a U.S. federal income tax return concurrently with the Form W-7 is required. There are exceptions, such as for certain treaty benefits or specific exemptions, but generally, the ITIN is issued to facilitate tax compliance, which includes filing returns.
Is the former USSR–U.S. tax treaty relevant for my Substack income in Azerbaijan?
The former USSR–U.S. tax treaty generally addresses withholding on certain types of income. While it might offer some benefits, its application to digital services income or freelance earnings from platforms like Substack requires specific analysis. It's advisable to consult with a tax professional knowledgeable about this treaty to determine if it applies to your situation.
