Why Substack Writers in Saudi Arabia Need an ITIN
Substack writers based in Saudi Arabia face a specific tax reporting challenge when receiving payments from the platform. Stripe, the payment processor commonly used by Substack, requires tax identification numbers from non-U.S. persons who earn income through its services. For individuals who do not have and are not eligible for a Social Security Number (SSN), the IRS mandates the use of an Individual Taxpayer Identification Number (ITIN). This ITIN serves as your unique taxpayer identification for U.S. tax purposes, enabling compliance with IRS reporting requirements. Without an ITIN, you may face backup withholding on your earnings, impacting your net income and creating administrative hurdles with Stripe and the IRS. The process of obtaining an ITIN is distinct for individuals in Saudi Arabia, requiring careful attention to documentation and submission procedures.
When You Need an ITIN for Substack Income
An ITIN is required for Substack writers in Saudi Arabia if you are receiving payments that are subject to U.S. tax reporting and you do not have an SSN. Stripe, as a U.S.-based payment processor, is obligated by the IRS to collect tax information from its users. When you earn income from sources deemed U.S. in origin, such as through a U.S.-based platform like Substack, the IRS requires you to report this income. If you are not a U.S. citizen or U.S. resident alien, you will not be eligible for an SSN. The IRS then provides the ITIN as the alternative identification number for tax filing purposes. You will need to provide this ITIN to Stripe to avoid backup withholding at the highest rate (typically 24% for non-U.S. persons), which can significantly reduce your earnings. Therefore, obtaining an ITIN is not optional but a necessity for compliant and efficient receipt of your Substack earnings.
Required Documentation for Your ITIN Application
To apply for an ITIN, you must complete Form W-7, Application for IRS Individual Taxpayer Identification Number. This form requires your personal information, including your name, address, and date of birth. Critically, you must also submit original or certified copies of identification documents to prove your foreign status and identity. The preferred primary identification document is a valid passport. If you do not have a passport, other documents like a national identity card, driver's license, or birth certificate may be accepted, but a passport is strongly recommended. You will also need to include documentation that supports the reason for your ITIN application, such as a U.S. tax return you are filing. For Substack writers, this often involves 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.
The ITIN Application Process: Step-by-Step
The ITIN application process begins with accurately completing Form W-7. This form requires specific details about your identity and the reason for your application. For Substack writers in Saudi Arabia, the primary reason is to report U.S. source income. You must then gather your supporting documentation, including your completed U.S. tax return (e.g., Form 1040-NR) and your primary identification document, typically a passport. Once compiled, you have three main options for submitting your application to the IRS: mail the original documents to the IRS ITIN Operation center in Austin, Texas; apply through a Certified Acceptance Agent (CAA); or schedule an appointment at a designated IRS Taxpayer Assistance Center (TAC). The CAA route is generally the fastest and safest, as they can verify your original documents and forward your application without you having to mail your originals. The IRS processes ITIN applications typically within 5–10 business days when submitted through a CAA. If mailed directly to the IRS, processing can take significantly longer, often 10–12 weeks or more, especially during peak tax seasons.
Common Mistakes for Substack Writers in Saudi Arabia
Substack writers in Saudi Arabia often make specific errors when applying for an ITIN. One common pitfall is failing to include a complete U.S. tax return with the Form W-7. The IRS requires proof that you are filing a U.S. tax return to justify the need for an ITIN. Simply stating you earn income from Substack is not sufficient; the income must be reported on the appropriate tax form. Another frequent mistake is using a name on the Form W-7 that does not exactly match the name on the identification document submitted, such as a passport. Minor discrepancies can lead to rejection. Additionally, some writers may attempt to submit photocopies of their passport instead of original or certified copies, which the IRS will not accept when applying directly. Lastly, misunderstanding U.S. tax residency rules or incorrectly applying tax treaty benefits can lead to errors in the tax return itself, which is a required part of the ITIN application package.
Benefits of Using a Certified Acceptance Agent (CAA)
Applying for an ITIN through a Certified Acceptance Agent (CAA) offers significant advantages, especially for individuals outside the U.S. like those in Saudi Arabia. A CAA is an individual or entity authorized by the IRS to assist taxpayers in obtaining ITINs. When you apply through a CAA, such as itin.net, they review your Form W-7 and verify your original identification documents. This verification process means you do not have to mail your valuable original documents, like your passport, directly to the IRS, reducing the risk of loss or delay. The CAA then forwards your completed application package to the IRS on your behalf. This streamlined process typically results in much faster processing times, often within 5–10 business days, compared to the many weeks or months it can take when mailing documents directly. Utilizing a CAA provides peace of mind and efficiency, ensuring your application is complete and correctly submitted from the outset.
Next Steps After Obtaining Your ITIN
Once you receive your ITIN from the IRS, usually via mail in the form of a CP-565 notice, you must update your information with Stripe. Providing your ITIN to Stripe will stop any backup withholding and ensure proper tax reporting for your Substack earnings moving forward. Beyond tax reporting, having an ITIN can be beneficial for other financial activities in the U.S. It can be used to open a U.S. bank account or to establish credit. For Substack writers in Saudi Arabia, maintaining accurate U.S. tax compliance is an ongoing process. Regularly review your income and filing obligations each tax year. If you find yourself needing to establish a U.S. business entity or require assistance with other U.S. tax matters, services like itin.net can help.

Practical tips
- Use the exact same legal name on your Form W-7, your passport, and any other supporting documents to avoid mismatches that cause application delays or rejections.
- Ensure your U.S. tax return (e.g., Form 1040-NR) is fully completed and signed before submitting it with your Form W-7. An incomplete tax return is a common reason for ITIN application denial.
- If you have any U.S. visas or previous U.S. tax filings, include copies of these documents with your Form W-7 application as they can strengthen your case and identity verification.
- Double-check the mailing address for the IRS ITIN Operation if you choose to mail your application directly. Incorrect addresses can lead to significant delays or lost documents.
- Once you have your ITIN, immediately update your tax information with Stripe to prevent backup withholding on future Substack payments and ensure accurate reporting.
Frequently asked questions

Can I use my Saudi national ID instead of a passport for my ITIN application?

What if my legal name has changed since my passport was issued?
If your legal name has changed, you must provide official documentation supporting the name change, such as a marriage certificate or court order, along with your passport showing your previous name. Ensure all documents are consistent or provide proof of the change.
Can I open a U.S. bank account with an ITIN?
Yes, many U.S. banks allow non-residents to open a U.S. bank account using an ITIN, especially if you have a U.S. address or are using a service that facilitates this. An ITIN is often a key requirement for such accounts.
