Substack Writers in Poland Face Unique ITIN Challenges
Substack writers based in Poland often encounter a specific hurdle when their U.S. income reaches reporting thresholds: the need for an Individual Taxpayer Identification Number (ITIN). Unlike U.S. citizens or residents, Polish writers earning through platforms like Substack may not have a Social Security Number (SSN), making the ITIN essential for tax compliance. This requirement stems from U.S. tax law, which mandates reporting of income earned from U.S. sources, even by non-residents. The typical friction point is receiving payout notifications from platforms like Stripe, which often flag the need for an ITIN or Employer Identification Number (EIN) to avoid backup withholding. For a Polish writer, this means understanding not just the general ITIN application process but also how it interacts with their specific income streams and the U.S. tax system.
When You Need an ITIN as a Polish Substack Writer
An ITIN is required for Polish Substack writers when they earn income sourced from the United States that exceeds certain reporting thresholds or when required by a U.S. payer. Platforms like Substack, which facilitate payments often through U.S.-based processors like Stripe, are obligated to report payments made to non-U.S. persons to the IRS. If you are a non-resident alien who does not have and cannot obtain an SSN, and you have a U.S. tax filing requirement, you need an ITIN. This typically includes earning more than $600 in a calendar year from a U.S. source that requires reporting on a Form 1099, or if you are claiming tax treaty benefits. The U.S. has a tax treaty with Poland, but claiming its benefits often necessitates filing a U.S. tax return and thus an ITIN. Without an ITIN, U.S. payers may be forced to withhold taxes at the highest applicable rate, impacting your net earnings.
Required Documents for Your ITIN Application
Applying for an ITIN involves submitting Form W-7 along with original or certified copies of identification documents to the IRS. The primary document proving your identity and foreign status is typically your 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 preferred by the IRS. You must also include a U.S. federal tax return with your Form W-7 submission, unless you qualify for an exception. For many Substack writers, this will be a Form 1040-NR (U.S. Nonresident Alien Income Tax Return). Ensure all documents are current and clearly legible. Missing or invalid identification is a common reason for application delays or rejections.
The ITIN Application Process for Polish Residents
The ITIN application process involves several key steps. First, you must complete Form W-7 accurately. This form collects personal information, details about your need for an ITIN, and your U.S. federal tax filing obligations. Second, you must attach your U.S. federal tax return. For most Substack writers in Poland, this will be a Form 1040-NR. Third, you need to submit your original or certified identification documents. The most common and efficient method for U.S. residents is to use a Certified Acceptance Agent (CAA). This allows you to submit your application and supporting documents without mailing your original passport. For individuals applying from Poland, you can mail your application directly to the IRS Austin Service Center or use a CAA. Direct mailing can take longer, as the IRS will retain your original identification documents for several weeks. Processing times for ITIN applications can vary, but when filed correctly through a CAA, the IRS typically issues the ITIN within 5–10 business days. Direct mail applications can take several months.
Common Mistakes for Polish Substack Writers
Polish Substack writers often make specific errors when applying for an ITIN. A frequent mistake is failing to include a complete and accurate U.S. federal tax return with Form W-7. This return must be ready to file, not just a draft. Another common pitfall is submitting incorrect or insufficient identification documents; remember, your passport is the preferred document. Mismatched names between your identification, Form W-7, and your tax return can also cause delays. For those claiming treaty benefits, incorrect or incomplete treaty claims on the tax return are a significant issue. Finally, sending photocopies instead of original or certified identification documents, or mailing original documents directly to the IRS without using a CAA, can lead to prolonged processing or loss of important personal identification.
Benefits of Using a Certified Acceptance Agent (CAA)
Using a Certified Acceptance Agent (CAA) significantly streamlines the ITIN application process, especially for individuals outside the United States. A CAA, such as itin.net, is authorized by the IRS to review your documentation, verify your identity, and forward your application directly to the IRS. This means you do not have to mail your original identification documents, such as your passport, to the IRS. Instead, the CAA authenticates these documents on your behalf. This greatly reduces the risk of losing critical identification and typically speeds up the processing time. The IRS generally processes applications submitted by a CAA much faster, often within 5–10 business days, compared to direct mail applications which can take many months. This service provides peace of mind and a more predictable timeline for receiving your ITIN.
Next Steps After Obtaining Your ITIN
Once you receive your ITIN from the IRS, usually in the form of a CP-565 letter, you can use it for all future U.S. tax filings and to provide to U.S. payers to avoid backup withholding. You will need your ITIN to file your annual U.S. tax return (Form 1040-NR) and to claim any applicable tax treaty benefits. If you plan to form a U.S. business entity, such as a U.S. LLC, an ITIN might be necessary for certain registration processes or for opening a U.S. bank account. For Substack writers, having an ITIN ensures accurate tax reporting and compliance with U.S. regulations.

Frequently asked questions
Do Substack writers in Poland need an ITIN if they only receive payments in Euros?
Even if payments are processed in Euros, the income is considered U.S. sourced if it originates from a U.S. platform like Substack. If the total U.S. sourced income meets IRS reporting thresholds, you will likely need an ITIN to comply with U.S. tax obligations.
How long does it take to get an ITIN from Poland?
When applying through a Certified Acceptance Agent (CAA), the IRS typically processes ITIN applications within 5–10 business days. If you mail your application directly to the IRS, it can take several months.
Can I use my Polish national ID card instead of my passport for the ITIN application?
While a passport is the preferred identification document for ITIN applications, other government-issued identification documents may be accepted. However, using a passport significantly increases the chances of your application being approved without delays. Always check the latest IRS guidelines for acceptable identification.
What is the difference between an ITIN and an EIN for a Polish Substack writer?
An ITIN is for individuals who need a U.S. tax ID but cannot get an SSN. An EIN is for businesses. As a sole proprietor earning income through Substack, you will likely need an ITIN. If you form a U.S. business entity like a U.S. LLC, you might need an EIN, which can be applied for using Form SS-4.
Do I need to file a U.S. tax return to get an ITIN?
Generally, yes. You must file a U.S. federal tax return with your Form W-7 to obtain an ITIN, unless you qualify for a specific exception. For Substack writers, this is typically Form 1040-NR.
Can itin.net help me get an ITIN if I live in Poland?
