ITIN Renewal for mobile app developers from Greece

Mobile app developers in Greece need to renew their ITIN for U.S. royalty payments. Learn the process, required documents, and common pitfalls to ensure timely compliance.

Why Mobile App Developers in Greece Need ITIN Renewal

Apple and Google require U.S. tax forms from developers worldwide, including those in Greece, to process royalty payments for apps and in-app purchases (IAPs). If you previously obtained an ITIN for this purpose and it has expired, you must renew it to continue receiving payments without excessive withholding. An expired ITIN can lead to a default 30% U.S. tax withholding on your earnings, significantly impacting your income. This situation is particularly relevant for mobile app developers in Greece who rely on consistent payouts from these platforms. Proactive ITIN Renewal is key to avoiding payment disruptions and ensuring you receive your net earnings as intended under any applicable tax treaty provisions.

When ITIN Renewal is Required for Greek Developers

Your ITIN requires renewal if it has expired due to non-use on a federal tax return for three consecutive years, or if the IRS has updated its middle-digit expiration schedule. For mobile app developers in Greece, the most common trigger for needing to renew an ITIN is the platform's requirement to have a valid U.S. taxpayer identification number on file. If your existing ITIN has lapsed, and you continue to earn royalties from Apple or Google, you will likely face the highest statutory U.S. withholding rate until a valid ITIN is provided. The IRS may also send a CP-48 notice if your ITIN has expired due to non-use, but relying on this notice is risky as many filers do not receive one. It's better to proactively check your ITIN status. The Greece–U.S. tax treaty may offer reduced withholding rates, but these benefits require a valid ITIN to be claimed.

Required Documents for ITIN Renewal

To renew your ITIN, you will typically need your most recent ITIN letter from the IRS, if available. This helps confirm your previous ITIN. The IRS also requires original or certified copies of identification documents to verify your identity. For most applicants, a valid passport is the primary document used. Ensure your passport is current and contains your full legal name, as it appears on other documentation. You will also need to file a current federal tax return with your renewal application. This tax return must be complete and accurate. If you are applying as a non-resident alien, this will likely be Form 1040-NR.

The ITIN Renewal Application Process

Renewing your ITIN involves completing IRS Form W-7 and selecting the 'Renew an Existing ITIN' box. You must attach your completed federal tax return and original or certified copies of your identification documents to this form. You have two primary options for submitting your application: mailing it directly to the IRS or applying through a Certified Acceptance Agent (CAA). The IRS processing times for direct submissions can be lengthy, often taking several months. Applying through a CAA, such as itin.net, significantly speeds up the process. A CAA can review your application, verify your original identification documents, and forward your application to the IRS. This method typically results in a turnaround time of 5–10 business days for the ITIN renewal itself, although the IRS may take additional time to process the associated tax return.

Common Mistakes for Greek Mobile App Developers

Mobile app developers in Greece often encounter specific pitfalls during ITIN renewal. One common error is failing to update personal information. If your legal name has changed since your last ITIN application, ensure all documents (passport, tax return, Form W-7) reflect the new name consistently. Mismatched names are a frequent cause for rejection. Another issue is not understanding the tax implications of the Greece–U.S. tax treaty. While the treaty can reduce withholding rates, you must claim these benefits correctly on your tax return and have a valid ITIN. Ensure your tax return accurately reports your income and claims any applicable treaty benefits. Finally, many developers delay renewal until they receive a CP-48 notice, which is not a reliable notification method; proactive renewal is always best.

Benefits of Using a Certified Acceptance Agent (CAA)

Applying for ITIN Renewal through a Certified Acceptance Agent (CAA) streamlines the process and reduces the risk of errors. As a CAA, itin.net can authenticate your original identification documents, such as your passport, meaning you do not have to mail your originals to the IRS. This verification by the CAA also often expedites the IRS's review of your application. The typical timeline for ITIN issuance or renewal via a CAA is significantly shorter than direct IRS submission, often within 5–10 business days for the ITIN itself. This expedited service is invaluable for mobile app developers in Greece who need their ITIN to ensure correct withholding on royalty payments and avoid potential disruptions. Using a CAA provides an added layer of assurance that your application meets IRS requirements before it's sent to them.

Next Steps After ITIN Renewal

Once your ITIN renewal is complete, ensure you update your new or renewed ITIN with Apple and Google immediately. This step is critical to ensure they apply the correct U.S. tax withholding rates going forward, especially if you are claiming benefits under the Greece–U.S. tax treaty. Keep records of your renewed ITIN and all submitted documentation for your personal tax files. If you are also setting up a U.S. business entity, such as a U.S. LLC, to manage your app development income, ensure your ITIN is correctly linked to that entity's filings.

Practical tips

  • Use the same legal name across your Form W-7, your passport, and any prior IRS correspondence. Mismatched name fields are the most common cause for ITIN renewal rejection.
  • Ensure your Form 1040-NR is complete and accurate before submitting it with your Form W-7 for renewal. Incomplete or incorrect tax returns will cause delays or rejections.
  • Do not wait for an IRS CP-48 notice to renew your ITIN. Check your ITIN status proactively, as the IRS may not send this notice, and your ITIN could expire due to non-use.
  • If you have previously applied for an EIN or other U.S. tax identification numbers, ensure consistency in your personal information provided across all applications.
  • Understand that the Greece–U.S. tax treaty may reduce withholding rates on your app royalties. Ensure you correctly claim these benefits on your U.S. tax return when submitting your ITIN renewal.

Frequently asked questions

How long does it take to renew my ITIN as a mobile app developer in Greece?

Through a Certified Acceptance Agent (CAA) like itin.net, the ITIN renewal process typically takes 5–10 business days for the ITIN issuance. Mailing directly to the IRS can take several months, plus the time to process your tax return.

Do I need a U.S. address to renew my ITIN?

You do not necessarily need a U.S. address to renew your ITIN. Your application requires your foreign address, and you can use a U.S. address if you have one (e.g., through a representative or service provider), but it is not mandatory for renewal.

Can I use my Greek driver's license as identification for ITIN renewal?

While foreign driver's licenses can sometimes be used, a valid passport is the most universally accepted identification document for ITIN renewal. Ensure your passport is current and matches your name on other documents.

What happens if I don't renew my ITIN and continue earning royalties?

If your ITIN expires and you do not renew it, Apple and Google will likely apply the highest statutory U.S. withholding tax rate (currently 30%) to your royalty payments. This can significantly reduce your net earnings.

Does the Greece–U.S. tax treaty affect my ITIN renewal?

Yes, the Greece–U.S. tax treaty may allow for reduced withholding rates on your royalty income. However, to claim these benefits, you must have a valid ITIN and file a U.S. tax return correctly claiming treaty provisions.

Should I form a U.S. LLC before renewing my ITIN?

Forming a U.S. LLC is a separate process from ITIN renewal. While some developers choose to form an LLC to manage their U.S. income, you can renew your ITIN without one. If you plan to form an LLC, consult with a tax professional about the best order of operations for your specific situation.
