Substack Writers in Hungary Face Unique Tax Reporting Hurdles
Substack writers based in Hungary who receive payments processed through Stripe face a specific tax reporting challenge when earning U.S. income. Stripe, as a U.S.-based payment processor, is required by the IRS to report these payments. To avoid backup withholding at a 30% statutory rate, you typically need to provide a U.S. taxpayer identification number. For individuals who cannot obtain a Social Security Number (SSN), the alternative is an ITIN (Individual Taxpayer Identification Number). This is a 9-digit IRS tax ID for individuals who must file U.S. taxes but cannot get an SSN. The termination of the Hungary-U.S. tax treaty in 2024 means that Hungary-based individuals can no longer rely on treaty provisions to reduce U.S. withholding tax rates on certain types of income. This makes obtaining an ITIN even more critical for Substack writers to ensure their U.S. tax obligations are met correctly and to potentially avoid higher withholding taxes on their earnings.
When Substack Writers in Hungary Need an ITIN
You generally need an ITIN if you are a non-resident alien receiving income from U.S. sources and are required to file a U.S. tax return, or if a U.S. payer (like Stripe for Substack payouts) requires one for tax reporting purposes. For Substack writers in Hungary, the trigger is typically the payment processing. Stripe, acting as a withholding agent, needs your U.S. tax identification number to report your income to the IRS. Without an SSN, the ITIN becomes necessary to fulfill this requirement. This is especially relevant as the Hungary-U.S. tax treaty is no longer in effect, meaning standard U.S. withholding rates apply. You may also need an ITIN if you are claiming treaty benefits under another country's tax treaty, though this is less common for residents of Hungary post-treaty termination. Filing a U.S. tax return, such as Form 1040-NR (U.S. Nonresident Alien Income Tax Return), is often a prerequisite for obtaining an ITIN, unless you qualify for an exception.
Essential Documents for Your ITIN Application
Applying for an ITIN requires submitting specific documentation to the IRS. The primary form is the Form W-7, Application for IRS Individual Taxpayer Identification Number. This form collects your personal information, reason for applying, and U.S. tax obligations. Alongside the Form W-7, you must submit original or certified copies of documents proving your identity and foreign status. The most commonly accepted document is a valid passport. If you do not have a passport, other documents like a birth certificate, national identity card, or driver's license may be accepted, but they must be accompanied by a foreign passport or other supporting identification. You will also need to include a U.S. tax return with your application, unless you qualify for an exception. For Substack writers in Hungary, ensure your passport is current and that all names match exactly across all submitted documents. Any discrepancies can lead to delays or rejection of your application.
The ITIN Application Process: A Step-by-Step Guide
The process for obtaining an ITIN involves several key steps. First, you must complete Form W-7. This form requires detailed personal information and the reason for your ITIN application. Next, you need to gather your supporting identification documents, such as a valid passport. Crucially, you must also prepare the U.S. tax return you are filing. Once these are assembled, you can submit your application. You have three main options for submission: mail your application and original supporting documents directly to the IRS, apply through an IRS-authorized Acceptance Agent, or visit an IRS Taxpayer Assistance Center (TAC) that offers ITIN application services. Mailing directly to the IRS means you risk losing your original documents for an extended period. Using an IRS-authorized Acceptance Agent, like itin.net, allows you to submit copies of your identification documents, keeping your originals. The typical timeline for receiving an ITIN is 5–10 business days when filed via a Certified Acceptance Agent (CAA). Direct submissions to the IRS can take significantly longer, often 10–12 weeks or more, especially during peak tax seasons.
Common Mistakes for Hungarian Substack Writers Applying for ITIN
Substack writers in Hungary often encounter specific pitfalls when applying for an ITIN. A frequent error is failing to include a complete and accurate U.S. tax return with the Form W-7. Without a valid tax return (unless an exception applies), your ITIN application will be rejected. Another common issue is mismatched names across documents. Ensure the name on your Form W-7, your passport, and any other identification or tax documents is identical. The termination of the Hungary-U.S. tax treaty adds another layer of complexity; incorrectly attempting to claim treaty benefits that are no longer applicable can lead to application denial. Furthermore, some applicants mistakenly believe they need an ITIN solely for receiving payments, without understanding the underlying requirement to file a U.S. tax return. Finally, sending original identification documents directly to the IRS without using a Certified Acceptance Agent poses a risk of loss.
Benefits of Using a Certified Acceptance Agent (CAA)
Applying for an ITIN through a Certified Acceptance Agent (CAA) offers significant advantages, particularly for individuals who prefer not to mail their original identification documents to the IRS. As a CAA, itin.net can verify your original identification documents, such as your passport, and send certified copies along with your Form W-7 to the IRS. This means you retain your original documents throughout the entire process, eliminating the risk of them being lost or delayed in transit. This service is invaluable for international applicants who rely on their passports for travel. Additionally, CAAs are trained by the IRS to correctly complete the Form W-7 and ensure all required documentation is present, which can help expedite the review process and reduce the likelihood of common application errors. The typical processing time when using a CAA is substantially faster, often within 5–10 business days, compared to mailing directly to the IRS.
Next Steps After Obtaining Your ITIN
Once you receive your ITIN (often via IRS Letter CP-565), you can use it for your U.S. tax filings and to provide to payers like Stripe for tax reporting. This allows Stripe to correctly report your Substack earnings to the IRS and avoid the 30% backup withholding. You will need to file a U.S. tax return annually if you continue to earn U.S. source income. If you are forming a U.S. business entity, such as a U.S. LLC, you will likely need an EIN (Employer Identification Number) instead of an ITIN for business purposes. Understanding your ongoing U.S. tax obligations is key.

- Double-check the termination date of the Hungary-U.S. tax treaty (2024) and do not claim treaty benefits that are no longer applicable.
- Use a Certified Acceptance Agent (CAA) to verify your identity documents, allowing you to keep your originals.
Frequently asked questions
Do I need an ITIN if I'm a Substack writer in Hungary and get paid via Stripe?
Yes, if Stripe requires a U.S. taxpayer identification number for tax reporting purposes and you do not have an SSN, you will need an ITIN. This allows Stripe to report your U.S. source income correctly to the IRS and avoid backup withholding.
How long does it take to get an ITIN as a writer in Hungary?
When applying through a Certified Acceptance Agent (CAA) like itin.net, the process typically takes 5–10 business days. If you mail your application directly to the IRS, it can take 10–12 weeks or longer.
Can I use my Hungarian driver's license or national ID to apply for an ITIN?
While a passport is the preferred document, other identification documents like a national identity card or driver's license may be accepted if accompanied by a foreign passport or another form of identification. Check the IRS guidelines for a full list of acceptable documents.
What happens to U.S. tax withholding for Hungarian writers now that the tax treaty is terminated?
With the termination of the Hungary-U.S. tax treaty in 2024, U.S. statutory withholding rates (typically 30%) will generally apply to U.S. source income for Hungarian residents, unless specific exceptions or alternative treaty benefits from another country apply.
Do I need an ITIN if I also have an EIN?
An ITIN is for individuals, while an EIN is for businesses. If you are earning income as an individual Substack writer, you need an ITIN. If you operate a U.S. business entity (like a U.S. LLC), you would need an EIN for that business.
Can I apply for an ITIN without filing a U.S. tax return?
Generally, you must file a U.S. tax return with your Form W-7 application. However, there are limited exceptions, such as for certain non-resident aliens who are not required to file a return but need an ITIN for other specific reasons. Consult IRS documentation or a tax professional for details.
