Why Substack Writers in Greece Need ITIN Renewal
As a Substack writer based in Greece, your U.S. federal tax reporting obligations are likely triggered by Stripe payouts. Stripe, a U.S.-based payment processor, is required to report these payments to the IRS. To do this accurately, they need your U.S. taxpayer identification number. For individuals who are not U.S. citizens or residents, this is typically an Individual Taxpayer Identification Number (ITIN). If your existing ITIN has expired, you must renew it to ensure continuous compliance and avoid potential issues with your U.S. tax filings and payment processing. The IRS mandates that U.S. persons and resident aliens file an annual return of worldwide income. Non-resident aliens with U.S. source income also have reporting requirements. Without a valid ITIN, you may face backup withholding on your earnings, and your tax filings will be incomplete, impacting your ability to claim treaty benefits or accurately report your income to both the IRS and Greek tax authorities.
When ITIN Renewal Becomes Necessary
Your ITIN may require renewal for two primary reasons. The first is if the IRS has deactivated it due to non-use on a federal tax return for three consecutive years. The second, more common reason for ITIN renewal is the IRS's rolling expiration schedule. Under this schedule, ITINs are deactivated based on the middle digits of the number. For example, ITINs ending in '70' expired in 2020, '71' in 2021, '72' in 2022, and so on. As a Substack writer receiving U.S. income, it is critical to have a valid ITIN. Failure to renew can lead to issues with Stripe, including backup withholding at the highest applicable rate. This means a significant portion of your earnings could be withheld before you receive them. Proactively checking your ITIN status is far more efficient than waiting for a notice from the IRS, such as a CP-48 notice, which may not be sent to all individuals whose ITINs have expired.
Required Documentation for ITIN Renewal
Renewing your ITIN requires submitting IRS Form W-7, specifically with the 'Renew an Existing ITIN' box checked. Along with the W-7, you must provide original or certified copies of identity and foreign status documents. The most commonly accepted document for identity and foreign status is your valid U.S. passport. If you do not have a passport, other documents like a national identity card along with a birth certificate, or a foreign driver's license may be acceptable, provided they meet IRS criteria. It is also highly recommended to include your most recent U.S. federal tax return, if available. If you have an old ITIN notice from the IRS, including this can significantly expedite the process. Ensure all documents are valid and current; expired identification will not be accepted. The IRS has strict requirements for what constitutes acceptable documentation, so careful preparation is key.
The ITIN Renewal Application Process
The process for renewing your ITIN involves completing IRS Form W-7 and gathering the necessary supporting documents. You have two primary options for submitting your application. The first is to mail your application directly to the IRS. This method requires you to send original documents, which can be a concern for many applicants due to the risk of loss or damage during transit. Processing times for direct mail applications can also be lengthy, often taking several weeks. The second, and often preferred, method is to apply through a Certified Acceptance Agent (CAA). A CAA, like itin.net, can verify your original documents and forward your application to the IRS on your behalf. This means you retain your original documents throughout the process. The typical timeline for ITIN renewal through a CAA is much faster, often ranging from 5–10 business days for the agent's verification and submission, after which IRS processing takes additional time. The IRS aims to issue renewed ITINs within 7 weeks, though this can vary.
Common Pitfalls for Substack Writers in Greece
Substack writers in Greece often encounter specific challenges when renewing their ITIN. One common issue is inconsistent name information across documents. Your name on Form W-7 must precisely match your passport and any prior IRS correspondence. Even minor discrepancies, such as middle initials or suffixes, can cause delays or rejections. Another pitfall is failing to include a current U.S. federal tax return. While you can apply for an ITIN without filing a tax return in some circumstances (e.g., for specific exceptions), renewal typically requires attaching a return for the year the ITIN is needed. For writers, this means having your 2023 tax return ready for attachment if renewing in 2024. Furthermore, relying solely on Stripe notifications for ITIN status is risky. Stripe may eventually implement backup withholding if your ITIN is inactive, but they are not the primary source for ITIN validity. Proactive checks and renewals are essential to avoid surprises and ensure uninterrupted income flow.
Benefits of Using a Certified Acceptance Agent (CAA)
Applying for ITIN renewal through a Certified Acceptance Agent (CAA) offers distinct advantages, especially for individuals who prefer not to mail original documents. A CAA is an individual or entity authorized by the IRS to assist taxpayers in obtaining ITINs. When you use a CAA, they will review your Form W-7 and verify your original identification documents, such as your passport. Instead of sending these originals to the IRS, the CAA makes certified copies. This verification process allows you to keep your original documents. The CAA then submits the completed application package to the IRS on your behalf. This not only provides peace of mind by eliminating the risk associated with mailing original documents but also streamlines the process. The typical timeline for processing through a CAA is significantly reduced, often allowing for faster submission to the IRS. Services like itin.net act as CAAs, simplifying the ITIN renewal for U.S. non-residents.
Next Steps After ITIN Renewal
Once your ITIN renewal is approved by the IRS, you will receive a new ITIN notice or an updated ITIN on subsequent tax forms. It is crucial to update your new ITIN with Stripe and any other platforms or financial institutions that require it. This ensures that your earnings are reported correctly and that you avoid any potential backup withholding issues moving forward. If you are considering forming a U.S. business entity, such as a U.S. LLC, to manage your Substack income, you will need an Employer Identification Number (EIN) in addition to your ITIN. A U.S. bank account is also often necessary for managing U.S. income streams effectively. Review the itin.net Renewal Package pricing at $397 or contact us to discuss your specific needs.

What happens if my ITIN expires and I don't renew it?
Your ITIN may be deactivated by the IRS, which can lead to backup withholding on U.S. source income, delays in tax refunds, and difficulties in fulfilling U.S. tax obligations. Stripe may also begin withholding taxes from your payouts.
Can I use my Greek tax identification number instead of an ITIN for U.S. tax purposes?
No, your Greek tax identification number is for Greek tax purposes only. For U.S. tax reporting, you need a U.S. taxpayer identification number, which for non-residents is typically an ITIN.
