Why Hungarian Substack Writers Need ITIN Renewal

Substack writers in Hungary who receive payments via Stripe for their content often encounter U.S. tax reporting obligations. When Stripe, or other U.S. payment processors, require a U.S. taxpayer identification number, an ITIN (Individual Taxpayer Identification Number) is typically used by non-U.S. persons. The specific trigger for ITIN renewal for these writers arises when their existing ITIN has expired, either due to inactivity for three consecutive years or because the IRS has systematically updated its expiration schedule based on the ITIN's middle digits. Failing to renew an expired ITIN can lead to withholding at the highest statutory rate (currently 30% following the termination of the U.S.-Hungary tax treaty) on U.S. source income, impacting the net earnings of Hungarian Substack writers.

Eligibility and Triggers for ITIN Renewal

Your ITIN requires renewal if it has been inactive on a federal tax return for three consecutive tax years, or if the IRS has issued a notice (like CP-48) indicating its expiration based on their rolling schedule. For Substack writers in Hungary receiving payments through U.S. platforms like Stripe, an active ITIN is essential for accurate tax withholding and reporting. The IRS began a renewal program in 2019, systematically expiring ITINs based on the middle digits. For example, ITINs with the middle digits 70-82 expired in 2020, 70-87 in 2021, 70-88 in 2022, 70-89 in 2023, and 70-90 will expire in 2024. If your ITIN falls within these ranges and you haven't used it on a U.S. federal tax return recently, it likely needs renewal. It is always advisable to proactively check your ITIN status rather than waiting for an IRS notice, which may not always be sent. The primary trigger for renewal is the expiration of the ITIN itself, not necessarily a specific income threshold, though the need for tax reporting on Substack earnings makes it critical for this audience.

Required Documents for ITIN Renewal

To renew your ITIN, you must submit Form W-7 with the 'Renew an Existing ITIN' box checked. Along with the W-7, you will need to provide original identification documents or certified copies from the issuing agency. The most commonly accepted primary identification document is a valid passport. If your passport is expired, other documents like a national identity card, driver's license, or birth certificate may be acceptable, but a valid passport is strongly preferred. You should also include any previous IRS notices related to your ITIN, such as a CP-565 (Notice of ITIN Assignment) or CP-575 (Notice of ITIN Assignment). Crucially, you must include a current U.S. federal tax return with your W-7 application. This return demonstrates your need for an ITIN for tax purposes. Ensure all submitted documents are current and accurately reflect your legal name. Mismatched names across documents are a frequent cause of application delays or rejections.

The ITIN Renewal Application Process

The ITIN renewal process begins with completing Form W-7, clearly indicating that you are renewing an existing ITIN. You must attach this form to your current U.S. federal tax return. Then, you will submit the W-7, your tax return, and your original or certified copies of identification documents to the IRS. There are two primary methods for submission: directly to the IRS or through a Certified Acceptance Agent (CAA). Submitting directly to the IRS involves mailing your original documents, which will be returned to you. This can take an extended period. Alternatively, you can apply through a CAA, like itin.net. CAAs can verify your original identification documents on your behalf and forward your application to the IRS. This method typically returns your original documents much faster, often within 5–10 business days, and streamlines the overall process. Once the IRS processes your application, they will issue a new ITIN or confirm your existing one, sending you a CP-565 notice.

Common Mistakes for Hungarian Substack Writers

Substack writers in Hungary often make specific errors during the ITIN renewal process. One common pitfall is failing to include a complete and accurate U.S. federal tax return with the Form W-7. Without a valid tax return, the IRS will not process your renewal application. Another mistake is submitting incomplete or expired identification documents. Ensure your passport is valid and accurately reflects your name. Given the recent termination of the U.S.-Hungary tax treaty, writers may mistakenly believe they no longer need an ITIN or that treaty benefits still apply. This is incorrect; an ITIN is still required for tax reporting, and without treaty protection, withholding rates revert to the standard 30%. Overlooking the IRS's rolling expiration schedule and only acting when a CP-48 notice is received is also a frequent error. Proactive checking and renewal are key. Lastly, incorrect entries on the W-7, such as using a former name or entering the ITIN incorrectly, can lead to delays. Ensure consistency across all submitted documents.

Benefits of Using a Certified Acceptance Agent (CAA)

Applying for ITIN renewal through a Certified Acceptance Agent (CAA) offers distinct advantages for Substack writers in Hungary. A CAA, such as itin.net, is authorized by the IRS to assist taxpayers in obtaining ITINs and renewing existing ones. The primary benefit is that CAAs can authenticate your original identification documents, such as your passport, without you having to mail them to the IRS. This means your original documents are returned to you much faster, typically within 5–10 business days, significantly reducing the risk of loss or delay associated with postal services. Furthermore, CAAs review your Form W-7 and supporting documentation for completeness and accuracy before submitting them to the IRS. This pre-screening helps minimize errors and increases the likelihood of your application being accepted without further issues. Using a CAA provides peace of mind and a more efficient renewal experience, especially for those unfamiliar with U.S. tax procedures.

Next Steps After ITIN Renewal

Once your ITIN renewal is approved, the IRS will issue a new ITIN or confirm your existing one via mail, typically with a CP-565 notice. You should then update your ITIN with any platforms or financial institutions that require it, including Stripe, to ensure correct tax reporting and avoid the 30% backup withholding. For Substack writers in Hungary, this means ensuring your updated ITIN is correctly on file with Stripe for future payouts. If you are considering expanding your U.S. business activities, such as forming a U.S. LLC or opening a U.S. bank account, having a valid ITIN is often a prerequisite.

Practical tips

  • Ensure your name on Form W-7 exactly matches your passport and any previous IRS correspondence; inconsistencies are a primary reason for rejection.
  • Always include a complete U.S. federal tax return with your Form W-7 renewal application, even if you believe it's obvious.
  • Proactively check your ITIN status online or through a CAA; do not wait for an IRS notice like CP-48, as it may not be issued.
  • If you have an old ITIN notice (CP-565) or a prior year's tax return showing your ITIN, include copies with your renewal application.
  • Understand that the U.S.-Hungary tax treaty termination means U.S. source income is now subject to the standard 30% withholding rate without treaty protection.

Frequently asked questions

How long does ITIN renewal take for a Substack writer in Hungary?

The processing time for ITIN renewal can vary. If you apply directly to the IRS, it can take several weeks to months. Using a Certified Acceptance Agent (CAA) like itin.net typically speeds up the document verification and submission process, with the IRS processing time still taking several weeks after submission.

Do I need to submit original documents for ITIN renewal?

You must submit either original identification documents or certified copies from the issuing agency. A CAA can review your original documents and verify them, meaning you don't have to mail your originals to the IRS, which is a significant advantage.

What is the cost to renew an ITIN?

The IRS does not charge a fee to apply for or renew an ITIN. However, services provided by a Certified Acceptance Agent (CAA) or tax preparers for assistance with the application process will incur fees. The itin.net Renewal Package is priced at $397.

Can I use my Hungarian national ID card instead of a passport for ITIN renewal?

While a valid passport is the preferred primary identification document for ITIN renewal, other documents like a national identity card or driver's license may be accepted if they meet IRS requirements. However, a passport is generally the most straightforward option. Ensure any document provided is current and contains your full legal name.

What happens if my ITIN expires and I continue to receive Substack payments?

If your ITIN expires and you do not renew it, Stripe and other U.S. payment processors may be required to withhold taxes at the highest statutory rate, which is currently 30% for payments to non-residents without a tax treaty benefit. This significantly reduces your net earnings. You will also face difficulties in filing U.S. tax returns accurately.

Do I need an ITIN if I am not a U.S. resident but earn money from a U.S. platform like Substack?

Yes, if you are earning income from U.S. sources, such as through Substack payments processed by U.S. entities like Stripe, and you are not a U.S. citizen or resident alien, you will likely need an ITIN for tax reporting purposes. This is especially true if you are not eligible for an Employer Identification Number (EIN).
