Substack writers in Slovenia face unique ITIN application challenges
Substack writers in Slovenia face a specific hurdle when receiving payments from U.S.-based platforms like Substack. These platforms often require a U.S. taxpayer identification number for tax reporting purposes, even if the writer is not a U.S. resident. For many, this means obtaining an Individual Taxpayer Identification Number (ITIN), a 9-digit IRS tax ID for those who must file U.S. taxes but cannot obtain a Social Security Number. The primary trigger for this requirement is often the payment processor, such as Stripe, which handles Substack payouts. Stripe, like other U.S. entities paying non-residents, must report these payments to the IRS. Without a U.S. taxpayer ID, they may be required to withhold a portion of your earnings at a higher rate. This situation is distinct from a general non-resident earning U.S. income; it's directly tied to the administrative requirements of digital publishing platforms and their payment infrastructure. Understanding this specific context is the first step in correctly obtaining your ITIN.
When you need an ITIN as a Substack writer in Slovenia
An ITIN is required for Substack writers in Slovenia primarily when U.S. entities, including Substack's payment processor, need to report payments made to you to the IRS. This typically occurs when you earn income that is considered U.S. source income. For Substack writers, this income is generated through your newsletter subscriptions and paid out via platforms like Stripe. Stripe, acting as a withholding agent, requires a U.S. taxpayer identification number to accurately report your earnings and any applicable tax withholdings. If you do not provide an ITIN or an Employer Identification Number (EIN), Stripe may be compelled to withhold a significant portion of your earnings, often at a flat rate of 30% for U.S. source payments to foreign individuals, as stipulated by Chapter 3 of the U.S. Internal Revenue Code. While an EIN is generally for business entities, an ITIN is the correct identification number for individuals. Given Slovenia has a tax treaty with the U.S., you might be eligible for reduced withholding rates, but you still need a valid ITIN to claim these treaty benefits on your U.S. tax filings, such as Form 1040-NR.
Required documentation for your ITIN application
To apply for an ITIN, you must accurately complete IRS Form W-7. This form requires detailed personal information, including your name, foreign address, and the reason for applying for an ITIN. The most common reason for Substack writers in Slovenia is to comply with U.S. tax reporting requirements for income earned from U.S. sources. Alongside the Form W-7, you must submit original or certified copies of documents verifying your identity and foreign status. The IRS strongly prefers a valid, unexpired passport as the primary identification document. If a passport is not available, other documents like a birth certificate, national identity card, or driver's license may be accepted, but these must be presented in conjunction with a document that establishes your identity. You will also need to provide documentation that supports your claim for needing an ITIN, such as a U.S. tax return (e.g., Form 1040-NR) or a letter from the entity requiring the ITIN. For Substack writers, this might involve a statement from Substack or Stripe indicating the need for a U.S. taxpayer ID for reporting purposes. Ensure all documents are current and clearly legible.
The ITIN application process and timeline
The ITIN application process begins with gathering your supporting documents and completing IRS Form W-7. You can submit your application directly to the IRS or through a Certified Acceptance Agent (CAA). Submitting directly to the IRS means mailing your original identification documents, which carries the risk of loss or delay. The typical timeline for direct submissions can range from 7 to 14 weeks, as the IRS processes these applications in batches. A more efficient and secure method is to apply through a CAA, such as itin.net. When you apply through a CAA, they verify your original documents on your behalf and forward the application to the IRS. This process significantly speeds up the application, with ITINs often issued within 5–10 business days after the CAA submits the application. The IRS will then mail your ITIN directly to you in the form of a notice, typically CP-565. After receiving your ITIN, you can provide it to Substack and Stripe to ensure accurate tax reporting and avoid excessive withholding. Remember to keep your ITIN safe, as it is a crucial piece of information for all future U.S. tax filings.
Common mistakes for Slovenian Substack writers applying for ITIN
Substack writers in Slovenia often make specific errors when applying for an ITIN. A frequent mistake is failing to provide a complete and accurate Form W-7. Missing information, such as your foreign address or the specific reason for applying, can lead to delays or rejection. Another common pitfall is not submitting adequate identification documents or submitting photocopies instead of originals or certified copies when required. For instance, relying solely on a driver's license without a primary ID like a passport can cause issues. Some writers also mistakenly believe they don't need an ITIN because they are not U.S. residents, overlooking the fact that U.S. source income triggers IRS reporting requirements. Incorrectly claiming treaty benefits without understanding the specific articles and conditions of the Slovenia-U.S. tax treaty can also lead to application problems. Ensure you correctly identify your tax residency status and the relevant treaty provisions if you plan to claim reduced withholding rates.
Benefits of using a Certified Acceptance Agent (CAA)
Using a Certified Acceptance Agent (CAA) like itin.net offers significant advantages for Substack writers in Slovenia applying for an ITIN. The most substantial benefit is the avoidance of mailing original identification documents to the IRS. Instead, the CAA authenticates your original documents on-site, returning them to you immediately. This significantly reduces the risk of loss or theft of crucial personal identification, such as your passport. Furthermore, CAAs are trained by the IRS to ensure your Form W-7 is filled out correctly and that all necessary supporting documentation is included. This drastically minimizes the chances of your application being rejected due to common errors, which can save you considerable time and frustration. The IRS processing time is also typically much faster when an application is submitted through a CAA, often resulting in an ITIN being issued within 5–10 business days, compared to the much longer processing times for direct submissions. The expertise of a CAA ensures a smoother, more secure, and faster ITIN application experience.
Next steps after receiving your ITIN
Once you receive your ITIN from the IRS, the immediate next step is to provide it to Substack and its payment processor, Stripe. This allows them to update your tax information and ensure that any future payments are reported correctly to the IRS without unnecessary withholding. If you experienced withholding on payments received before obtaining your ITIN, you may be able to claim a refund of that excess withholding when you file your U.S. non-resident tax return (Form 1040-NR) for the relevant tax year. It's also important to keep your ITIN in a secure place, as you will need it for any future U.S. tax filings or financial transactions requiring a U.S. taxpayer identification number. If you are considering other U.S. business ventures, such as forming a U.S. LLC or opening a U.S. bank account, your ITIN might be a prerequisite or a helpful document in those processes.

Practical tips
- Use the same legal name across Form W-7, your passport, and any prior IRS correspondence; mismatched name fields are a common rejection reason.
- Ensure your foreign address on Form W-7 is a physical address where you can receive mail from the IRS; a P.O. Box is generally not acceptable.
- If you are eligible for tax treaty benefits under the Slovenia-U.S. treaty, carefully review the treaty articles and ensure you meet all conditions before claiming them on your tax return.
- Keep copies of all documents submitted with your ITIN application, including your completed Form W-7 and identification documents, for your records.
- If you are unsure about any aspect of the ITIN application or U.S. tax obligations, consult with a qualified tax professional specializing in international taxation.
Frequently asked questions
Do I need an ITIN if I'm a Slovenian resident earning money from Substack?
Yes, if Substack's payment processor (like Stripe) requires a U.S. taxpayer identification number for IRS reporting purposes, you will likely need an ITIN. This is because the income is considered U.S. source income, and the IRS requires reporting.
Can I use my Slovenian tax identification number instead of an ITIN?
No, your Slovenian tax identification number is not a substitute for a U.S. ITIN. The ITIN is specifically for U.S. tax purposes and is issued by the IRS to individuals who do not have and are not eligible for a Social Security Number.
How long does it take to get an ITIN through a Certified Acceptance Agent (CAA)?
When applying through a CAA like itin.net, the process is typically much faster. After the CAA submits your application, the IRS usually issues the ITIN within 5–10 business days. The initial document verification by the CAA adds a short amount of time before submission.
What if my passport has expired?
An expired passport is generally not accepted as a primary identification document for ITIN applications. You should use a valid, unexpired passport. If a passport is unavailable, consult the IRS guidelines or a CAA for alternative acceptable documents.
Will I have to pay U.S. taxes on my Substack earnings?
Whether you owe U.S. taxes depends on the nature of your income and the tax treaty between Slovenia and the U.S. You may need to file a U.S. tax return (Form 1040-NR) to report your income and claim any treaty benefits. An ITIN is necessary for this reporting.
What happens if I don't get an ITIN?
If you don't provide an ITIN to platforms like Substack and their payment processors, they may be required to withhold a significant portion (often 30%) of your earnings as backup withholding. You might also face challenges in claiming any applicable tax treaty benefits.
