Why Portuguese Tax Refund Claimants Need ITIN Renewal
Foreign nationals in Portugal who are entitled to a U.S. tax refund, such as from over-withheld casino winnings, royalties, or dividends, often require an Individual Taxpayer Identification Number (ITIN) to file the necessary U.S. tax return, typically Form 1040-NR. If your existing ITIN has expired, you must renew it before you can claim this refund. An ITIN expires if it has not been used on a federal tax return for three consecutive years, or due to the IRS's staggered expiration schedule based on the middle digits. For Portuguese residents, this means any previously issued ITIN will need to be valid to file your 1040-NR and receive your refund from the IRS.
The primary friction point for Portuguese tax refund claimants is the inability to file their U.S. tax return without a valid ITIN. The IRS mandates that all individuals claiming U.S. tax refunds, even non-residents, must use an ITIN for identification purposes on their tax filings. Without a valid ITIN, the IRS will reject the tax return, and you will not receive your rightful refund. This situation is particularly relevant for individuals benefiting from Portugal's favorable tax environment, such as those participating in the NHR program, who may have U.S. income sources requiring tax filing and potential refunds.
Proactively checking your ITIN status is more effective than waiting for an IRS notice, as not all filers receive a CP-48 notice. The IRS has a rolling expiration schedule, and your ITIN might be invalid even if you haven't received a direct communication from them. Given the processing times for ITIN renewal, it is advisable to initiate the process well in advance of the tax filing deadline to ensure you can submit your claim on time. The itin.net ITIN Renewal Package provides a streamlined approach for this process.
When ITIN Renewal is Required for Portuguese Residents
ITIN Renewal is required when your previously issued ITIN is no longer valid for tax filing purposes. The IRS revokes an ITIN if it has not been used on a federal tax return for three consecutive tax years. Additionally, the IRS implements a rolling expiration schedule based on the middle digits of the ITIN. For example, ITINs with middle digits 70-82 expired starting in 2022, and further groups will expire in subsequent years. You can verify your ITIN's validity by checking the IRS's official list of expired ITINs or by consulting with a tax professional.
For tax refund claimants in Portugal, the trigger for ITIN Renewal is typically the need to file a U.S. tax return (Form 1040-NR) to claim a refund. This could be due to over-withheld taxes on U.S.-sourced income, such as dividends from U.S. stocks, royalties from U.S. intellectual property, or winnings from U.S. casinos. If your ITIN has expired, you cannot complete the necessary tax return, thus preventing you from receiving your refund. The U.S.-Portugal tax treaty may influence your U.S. tax obligations, but it does not exempt you from the requirement to have a valid ITIN for filing purposes.
It is crucial to remember that the IRS does not automatically notify taxpayers whose ITINs have expired unless they are actively expected to file a return in the current year. Therefore, if you have an expired ITIN and intend to claim a tax refund, you must proactively initiate the renewal process. Relying solely on receiving a CP-48 notice from the IRS is a common pitfall, as many individuals do not receive this notification even when their ITIN is no longer valid.
Required Documents for ITIN Renewal
To renew your ITIN, you will need to submit an application using IRS Form W-7 and check the box indicating 'Renew an Existing ITIN'. This form requires specific documentation to verify your identity and foreign status. The most critical document is generally a valid, unexpired passport. The passport serves as both proof of identity and nationality, satisfying the IRS requirements.
If you have an old ITIN notice from the IRS, it is highly recommended to include it with your application. While not always strictly required, this notice helps the IRS quickly identify your existing ITIN and process your renewal. In cases where a passport is not available, other original identification documents can be used, such as a national identification card, driver's license, or birth certificate, provided they meet IRS standards for acceptable identification. Each document must be accompanied by a U.S. federal tax return for which the ITIN is needed.
When applying for ITIN Renewal, ensure that the personal information on your Form W-7 and supporting documents is consistent. Any discrepancies in names, dates of birth, or other identifying information can lead to delays or rejection of your application. For Portuguese citizens, this means ensuring your name on Form W-7 exactly matches your passport and any other submitted identification. The IRS requires original documents or certified copies from the issuing agency. If submitting original documents, they will be returned to you by mail.
The ITIN Renewal Application Process
The ITIN Renewal process involves completing and submitting IRS Form W-7, along with supporting identification documents and a valid U.S. federal tax return. You must clearly indicate on Form W-7 that you are renewing an existing ITIN. The application can be submitted directly to the IRS, mailed to their Austin, Texas service center, or processed through a Certified Acceptance Agent (CAA).
When submitting directly to the IRS or by mail, you will need to send original identification documents or certified copies. The IRS will review your application, verify your documents, and process your renewal. This method can be time-consuming, with processing times potentially extending several weeks or even months. The IRS aims to process renewals within 8-10 weeks, but delays are common, especially during peak tax season.
Alternatively, applying through a Certified Acceptance Agent (CAA) significantly streamlines the process. A CAA, such as itin.net, can verify your original identification documents on your behalf, meaning you do not have to mail them to the IRS. This avoids the risk of losing important documents and often results in a faster turnaround time. The typical timeline for ITIN renewal through a CAA is 5–10 business days for the verification and submission process, after which the IRS processing time applies. This efficient path is why many Portuguese residents opt for a CAA for their ITIN Renewal needs.
Common Mistakes for Portuguese Tax Refund Claimants
A frequent mistake for Portuguese tax refund claimants is failing to renew their ITIN proactively. Many individuals wait until they receive an IRS notice, such as a CP-48, which may never arrive. By then, it might be too late to renew the ITIN and file the tax return to claim the refund before the statute of limitations expires. It is advisable to check your ITIN status periodically, especially if it has been unused for a few years.
Another common error is submitting incomplete or incorrect documentation. This includes providing expired identification, failing to include a valid tax return with the Form W-7, or having name discrepancies between documents. For instance, if your passport lists your name one way and your prior IRS correspondence another, the IRS may reject your application. Ensuring consistency across all submitted documents is vital for a smooth ITIN Renewal process.
For Portuguese residents, misunderstanding the U.S.-Portugal tax treaty implications can also lead to errors. While the treaty may reduce or eliminate U.S. tax on certain types of income, it does not negate the need for a valid ITIN to claim refunds of over-withheld taxes. Some individuals might incorrectly believe the treaty exempts them from filing altogether, missing out on potential refunds. It is important to consult with a tax professional specializing in U.S. expatriate taxation to fully understand your filing obligations and treaty benefits.
Benefits of Using a Certified Acceptance Agent (CAA)
Using a Certified Acceptance Agent (CAA), like those at itin.net, offers distinct advantages for Portuguese residents seeking ITIN Renewal. The primary benefit is that CAAs are authorized by the IRS to assist taxpayers in obtaining ITINs and renewing existing ones. They can verify your original identification documents, such as your passport, on your behalf.
This verification process by a CAA means you do not need to mail your original, sensitive documents directly to the IRS. This significantly reduces the risk of losing your passport or other vital identification during transit. CAAs handle the submission of your Form W-7 and supporting documents directly to the IRS, acting as an intermediary. This can expedite the initial stages of the application process.
The typical timeline for ITIN renewal through a CAA is often faster than direct submission to the IRS. While the IRS processing time itself remains the same, the CAA's efficient handling and verification of your application can prevent common errors that lead to delays. For tax refund claimants in Portugal, this means a quicker path to obtaining a valid ITIN, enabling them to file their tax return and claim their refund sooner. The itin.net ITIN Renewal Package is designed to leverage these benefits for clients.
Next Steps After ITIN Renewal
Once your ITIN Renewal is approved, you will receive a new ITIN or confirmation that your existing ITIN is valid. You can then proceed with filing your U.S. federal tax return, Form 1040-NR, to claim your tax refund. Ensure you use the correct and validated ITIN on all relevant tax forms.
If you are claiming a refund of over-withheld U.S. tax, it is essential to file your return accurately and promptly after receiving your renewed ITIN. The IRS has a statute of limitations for claiming refunds, generally three years from the date the original return was filed or two years from the date the tax was paid, whichever is later. A valid ITIN is necessary to meet this filing requirement.
For Portuguese residents, especially those involved with U.S. businesses or investments, maintaining a valid ITIN is an ongoing necessity. It may also be required for other financial activities in the U.S., such as opening a U.S. bank account or complying with U.S. reporting requirements related to foreign-owned entities.

Practical tips
- Use the same legal name across Form W-7, your passport, and any prior IRS correspondence; mismatched name fields are the most common rejection reason for ITIN applications.
- Ensure your passport is valid and has at least six months of validity remaining beyond your intended stay in the U.S., as required by the IRS for identification purposes.
- Include a complete and accurate U.S. federal tax return with your Form W-7 application; an ITIN will not be issued or renewed without a corresponding tax filing.
- If you are unsure about your ITIN's expiration status, check the IRS's official list of expired ITINs or consult with a tax professional before starting the renewal process.
- Consider using a Certified Acceptance Agent (CAA) to verify your original documents. This avoids mailing your passport to the IRS and can expedite the initial processing.
Frequently asked questions
How long does it take to renew an ITIN for someone in Portugal?
The IRS processing time for ITIN renewal can vary, but it typically takes 8-10 weeks. However, using a Certified Acceptance Agent (CAA) like itin.net can expedite the initial verification and submission, often resulting in a faster overall process compared to direct submission to the IRS.
Can I renew my ITIN if I haven't filed a U.S. tax return in three years?
Yes, if your ITIN has expired due to non-use for three consecutive years, you must renew it by submitting Form W-7 along with a federal tax return for which the ITIN is needed. This is common for tax refund claimants who may not have had U.S. tax obligations in prior years but now need to file to claim a refund.
What documents do I need to renew my ITIN if I am in Portugal?
You will need a completed Form W-7 (checking the 'Renew' box), a valid U.S. federal tax return, and original or certified copies of your identification documents. A valid passport is the preferred form of identification. If you use a Certified Acceptance Agent (CAA), they will verify your original documents for you.
Do I need a U.S. address to renew my ITIN?
You do not strictly need a U.S. address to renew your ITIN. You can use your Portuguese address on Form W-7. However, if you are claiming a refund, the IRS will mail the refund check to the address listed on your tax return, so ensure it is accurate and deliverable.
What is the difference between applying for a new ITIN and renewing an ITIN?
The primary difference is that for renewal, you check the 'Renew an Existing ITIN' box on Form W-7 and must provide your previously assigned ITIN. The supporting documentation requirements are similar, including a valid tax return and identification. The process is otherwise very similar, especially when using a Certified Acceptance Agent.
Will the U.S.-Portugal tax treaty affect my ITIN renewal?
The U.S.-Portugal tax treaty governs how certain income is taxed between the two countries, potentially reducing or eliminating U.S. tax obligations. However, it does not affect the requirement to have a valid ITIN for filing U.S. tax returns to claim refunds of over-withheld taxes. You still need to renew your ITIN if it has expired.
