Substack Writers in Kosovo Face Unique Tax Reporting Needs
Substack writers based in Kosovo who earn U.S. income face a specific tax reporting challenge. Unlike U.S. citizens or residents, you likely do not have a Social Security Number (SSN). However, platforms like Stripe, which process payouts for many Substack writers, are required by the IRS to report payments made to non-U.S. persons. This reporting often necessitates a U.S. taxpayer identification number, such as an Individual Taxpayer Identification Number (ITIN).
The primary trigger for needing an ITIN in this scenario is the IRS requirement for payers (like Stripe) to issue Form 1099 to non-U.S. persons who receive U.S. source income above certain thresholds. Without an ITIN, these platforms may withhold U.S. taxes at a higher rate (typically 30%) on your earnings. Obtaining an ITIN allows for accurate tax reporting and potentially reduces or eliminates this withholding, depending on tax treaty benefits (though Kosovo does not have a specific income tax treaty with the U.S.). This process ensures compliance with U.S. tax laws while minimizing your tax burden.
ITIN Eligibility and Triggers for Kosovo-Based Substack Writers
An ITIN is required if you are a non-resident alien who must file a U.S. tax return but cannot obtain an SSN. For Substack writers in Kosovo, this typically arises when you receive payments exceeding $600 from U.S.-based platforms like Stripe. These platforms are obligated to report these payments to the IRS. To avoid backup withholding at the highest rate (30%) and to file your U.S. tax return accurately, you will need an ITIN.
Even if backup withholding is not immediately applied, U.S. tax law requires non-residents with U.S. source income to report it. This means you may need to file a U.S. Nonresident Alien Income Tax Return (Form 1040-NR). Filing Form 1040-NR necessitates having a U.S. taxpayer identification number, which for individuals without an SSN, is an ITIN. The ITIN serves as your unique identifier for all U.S. federal tax purposes, including filing returns and receiving any applicable refunds.
Required Documents for Your ITIN Application
To apply for an ITIN, you must complete IRS Form W-7. This application requires you to submit original identification documents or certified copies from the issuing agency. The most commonly accepted primary identification document is a valid passport.
Other acceptable documents include a birth certificate, national identification card, driver's license, or foreign military identification card. You must also provide documents proving your foreign status, such as a visa or immigration card, if applicable. Crucially, you must include a U.S. federal income tax return with your Form W-7 application, unless you qualify for an exception. For Substack writers, this would typically be Form 1040-NR. The IRS reviews these documents to verify your identity and eligibility for an ITIN. Ensure all names match exactly across all submitted documents.
The ITIN Application Process: Step-by-Step
The application process for an ITIN involves several key steps. First, you must complete and sign IRS Form W-7, Application for IRS Individual Taxpayer Identification Number. This form collects personal information, including your name, address, and foreign status.
Next, you must assemble your supporting documentation. This includes your original, unexpired passport or certified copies of other identity documents, and your completed U.S. federal income tax return (e.g., Form 1040-NR). You then have two main options for submitting your application: mail it directly to the IRS or apply through a Certified Acceptance Agent (CAA). The CAA path is generally faster and more secure, as they can verify your original documents on your behalf. If you choose to mail your application, the IRS typically processes Form W-7 within 7 to 10 weeks. Using a CAA, like itin.net, significantly speeds up this process, often reducing it to 5–10 business days for document verification.
Common ITIN Application Mistakes for Kosovo Substack Writers
Substack writers in Kosovo often make specific errors when applying for an ITIN. A frequent mistake is failing to include a complete and accurate U.S. federal income tax return with Form W-7. Without this tax return, your ITIN application will be rejected unless you qualify for a specific exception. Remember, the ITIN is for tax processing purposes, so demonstrating a need to file U.S. taxes is paramount.
Another common pitfall is submitting incomplete or mismatched identification documents. Ensure the name on your Form W-7 exactly matches the name on your passport or other primary identification. Mismatched names are a leading cause of application delays or rejections. Additionally, some applicants mistakenly mail original identification documents directly to the IRS, risking their loss. Utilizing a Certified Acceptance Agent (CAA) prevents this by verifying your documents locally. Finally, incorrect claims regarding tax treaty benefits can cause issues, although this is less common for Kosovo residents due to the absence of a specific U.S. income tax treaty.
Applying Through a Certified Acceptance Agent (CAA)
Applying for an ITIN through a Certified Acceptance Agent (CAA) offers distinct advantages, particularly for individuals who prefer not to mail original documents to the IRS. As a CAA, itin.net can authenticate your original identification documents, such as your passport, on your behalf. This means you retain your original documents throughout the entire process.
The CAA acts as an intermediary, submitting your verified documentation and Form W-7 directly to the IRS. This streamlined process significantly reduces the time it takes for the IRS to process your application. While direct mailing to the IRS can take 7–10 weeks, applications submitted through a CAA are typically processed within 5–10 business days for the initial verification. This faster turnaround is invaluable for Substack writers who need their ITIN promptly to comply with reporting requirements and avoid backup withholding.
Next Steps After Receiving Your ITIN
Once the IRS approves your ITIN application, you will receive a CP-565, ITIN Assignment Letter, by mail. This letter contains your assigned ITIN. Keep this document secure, as you will need it for all future U.S. tax filings.
With your ITIN in hand, you can update your tax information with payment processors like Stripe. This allows them to file accurate tax forms (like Form 1099) with the IRS under your correct U.S. taxpayer identification number, potentially reducing or eliminating backup withholding. If you plan to establish a U.S. business entity, such as a U.S. LLC, an ITIN may also be necessary for certain filings, like Form 5472, or for opening a U.S. bank account.

Practical tips
- Ensure the legal name on your Form W-7 precisely matches your passport and any other identification documents to prevent rejection.
- Submit a complete and accurate U.S. federal income tax return (Form 1040-NR) with your Form W-7, as this is the primary requirement for most applicants.
- Use a Certified Acceptance Agent (CAA) to avoid mailing original identification documents to the IRS; the CAA will verify them locally.
- Allow ample processing time for your ITIN application; while CAAs expedite verification, the IRS still requires time to issue the number.
- Keep your ITIN secure once issued. You will need it for all future U.S. tax filings and potentially for U.S. business or banking needs.
Frequently asked questions
Do Substack writers in Kosovo need an ITIN if they don't have U.S. residency?
Yes, if you earn income from U.S. sources (like Substack payouts processed through U.S. platforms) and are required to file a U.S. tax return, you will likely need an ITIN. This is because U.S. payment processors must report your earnings to the IRS, and they require a U.S. taxpayer identification number.
How long does it take to get an ITIN from Kosovo?
When applying through a Certified Acceptance Agent (CAA) like itin.net, the verification of your documents typically takes 5–10 business days. The IRS then processes the application, which can take an additional 7–10 weeks to issue the ITIN itself. Applying directly to the IRS without a CAA can extend the entire process significantly.
What identification documents are acceptable for a Kosovo resident applying for an ITIN?
The most preferred document is a valid passport. Other acceptable documents include a birth certificate, national identification card, or driver's license. You must provide original documents or certified copies from the issuing agency. A CAA can verify these original documents for you.
Can I apply for an ITIN without filing a U.S. tax return?
Generally, no. A completed U.S. federal income tax return (like Form 1040-NR for non-residents) must accompany your Form W-7 application. There are limited exceptions, such as for certain individuals seeking ITINs for treaty benefits or specific tax treaty applications, but for most Substack writers earning U.S. income, filing a tax return is required.
What happens if Stripe or another platform withholds U.S. taxes from my Substack earnings?
If you do not provide a U.S. taxpayer identification number (like an ITIN), payment processors are often required to withhold U.S. taxes at a rate of 30%. Obtaining an ITIN allows you to provide this number, which can reduce or eliminate this withholding. You may also be able to claim a refund of excess withholding when you file your U.S. non-resident tax return.
Do I need an ITIN to open a U.S. bank account for my Substack earnings?
While not always strictly required by every bank, having an ITIN can significantly simplify the process of opening a U.S. bank account, especially if you are not a U.S. resident. Some banks require a U.S. taxpayer identification number for account setup and reporting purposes. You can learn more about options for opening a U.S. bank account.
