ITIN Renewal Requirements for Danish Rental Property Owners
Rental property owners in Denmark who hold an Individual Taxpayer Identification Number (ITIN) need to understand renewal triggers. Your ITIN may expire if it has not been used on a federal tax return for three consecutive years, or due to the IRS's periodic middle-digit expiration schedule. For non-residents with U.S. rental properties, this renewal is critical for filing Form 1040-NR, the U.S. Non-Resident Alien Income Tax Return, or if you've elected to treat your rental income as effectively connected with a U.S. trade or business under IRC §871(d).
Unlike U.S. citizens or residents who typically use a Social Security Number (SSN), foreign nationals require an ITIN for these U.S. tax filing obligations. The U.S. has a tax treaty with Denmark, which may affect withholding on certain types of income, but it does not eliminate the need for an ITIN to report rental income or comply with other U.S. tax laws. Failing to renew an expired ITIN can lead to issues with tax filings, potential penalties, and delays in processing any refunds or other tax matters.
When to Renew Your ITIN
The primary trigger for ITIN renewal is its expiration. The IRS initiates a rolling expiration schedule based on the middle digits of the ITIN. Additionally, if you have not filed a U.S. federal tax return using your ITIN for three consecutive tax years, the IRS will consider it inactive and it will expire. This non-use clause is particularly relevant for rental property owners who might only file when they have significant rental income or expenses to report.
The IRS may send a notice, such as CP-48, informing you of your ITIN's expiration, but it is not guaranteed. Many individuals do not receive this notice and must proactively check their ITIN status. For rental property owners in Denmark, it's advisable to check your ITIN status at least once a year, especially if you anticipate filing a U.S. tax return. The typical timeline for ITIN renewal processing can range from 5–10 business days when submitted through a Certified Acceptance Agent (CAA).
Required Documents for ITIN Renewal
To renew your ITIN, you will need to complete and submit IRS Form W-7, Application for IRS Individual Taxpayer Identification Number, specifically checking the box for 'Renew an Existing ITIN'. You must also include a valid U.S. federal tax return for the year you are claiming the ITIN for. If you have a prior ITIN notice from the IRS, such as a CP-565 or CP-48, it is helpful to include it with your application, though not strictly required.
The most critical document for proving identity and foreign status is your original, unexpired passport. If you do not have a passport, the IRS accepts certain alternative documents, but a passport is generally the preferred and most straightforward option. Ensure all submitted documents are either originals or certified copies from the issuing agency. If you are applying through a CAA, they can often verify your original documents and send certified copies on your behalf, avoiding the risk of mailing your original passport.
The ITIN Renewal Application Process
The renewal process begins with completing IRS Form W-7 and attaching your valid U.S. federal tax return. You must indicate that you are renewing an existing ITIN. You then submit your application package to the IRS. You have two primary options for submission: by mail directly to the IRS, or through an authorized Certified Acceptance Agent (CAA).
Submitting by mail can involve longer processing times and requires you to send original identification documents, which carry a risk of loss or damage. Alternatively, using a CAA like itin.net can significantly streamline the process. A CAA will verify your original identification documents, ensuring you do not have to mail them, and will forward your completed application to the IRS. This method typically results in a faster turnaround, often within 5–10 business days for the renewal confirmation.
Common Mistakes for Danish Rental Property Owners
Rental property owners in Denmark often make specific errors during ITIN renewal. One common issue is failing to include a complete and accurate federal tax return with the Form W-7. This return must be for the tax year for which you are claiming the ITIN. Ensure all necessary schedules related to rental income and expenses are attached.
Another frequent mistake involves mismatched identity information. The name and date of birth on your Form W-7 must exactly match those on your passport or other primary identification document. Minor discrepancies, such as a missing middle initial or a different spelling, can lead to rejection. Furthermore, some owners overlook the fact that their ITIN might have expired simply due to non-use, not waiting for an IRS notice, and thus miss renewal deadlines, impacting their ability to file timely U.S. tax returns.
Benefits of Using a Certified Acceptance Agent (CAA)
Using a Certified Acceptance Agent (CAA) offers distinct advantages for ITIN renewal, especially for non-residents like rental property owners in Denmark. A CAA is an individual or entity authorized by the IRS to assist applicants in obtaining ITINs. When you use a CAA, they are trained to review your application and verify your original identification documents, such as your passport.
This verification process means you do not have to mail your original documents to the IRS, mitigating the risk of them being lost or stolen in transit. The CAA forwards your application package to the IRS for processing. This often leads to a quicker turnaround time for your renewed ITIN compared to direct submission by mail. For services like itin.net, the typical processing window through a CAA is 5–10 business days.
Next Steps After ITIN Renewal
Once your ITIN renewal is approved, you will receive a new ITIN assignment letter from the IRS. This new number should be used on all future U.S. federal tax filings. If you had an existing ITIN, and it has been re-assigned to you, ensure you use that same number consistently. It is important to keep your renewed ITIN confirmation letter in a safe place for your records.
With your renewed ITIN, you can now proceed with filing your U.S. federal tax return for the relevant tax year. This ensures compliance with U.S. tax obligations related to your rental property income. If you are considering forming a U.S. LLC to manage your rental property, completing that process can provide liability protection.

Practical tips

Frequently asked questions
Do I need to renew my ITIN if I only own one rental property in the U.S. and live in Denmark?
Yes, if your ITIN has expired due to non-use for three consecutive years or by the IRS's middle-digit schedule, and you need it to file a U.S. tax return (like Form 1040-NR) for your rental property income, you must renew it. Proactive renewal is advised.
How long does it take to renew an ITIN through a Certified Acceptance Agent (CAA) in Denmark?
The typical processing time for an ITIN renewal through a CAA is 5–10 business days from when the application is submitted to the IRS. This is generally faster than mailing the application directly to the IRS.
What happens if my ITIN expires and I don't renew it before filing my U.S. rental property taxes?
If your ITIN has expired, the IRS will not be able to process your tax return effectively. This can lead to delays in refunds, potential penalties for late or inaccurate filing, and other issues with your U.S. tax obligations. You must have a valid ITIN to file.
Can I use my Danish driver's license as identification for ITIN renewal?
The IRS primarily requires a valid, unexpired passport for ITIN applications and renewals to verify identity and foreign status. While alternative documents may be accepted, a passport is the most reliable and preferred document. Check with the IRS or a CAA for specific alternative document requirements.
Is there a specific treaty benefit for Danish rental property owners that affects ITIN renewal?
While the U.S. has a tax treaty with Denmark that can affect withholding rates on certain U.S.-sourced income, it does not exempt you from the requirement to obtain or renew an ITIN if you have U.S. tax filing obligations, such as reporting rental income.
If I form a U.S. LLC for my rental property, does that change my ITIN renewal needs?
Forming a U.S. LLC does not eliminate your personal need for an ITIN if you are required to file U.S. taxes. The LLC itself might need an Employer Identification Number (EIN) if it has employees or certain other structures, but your personal tax obligations related to the rental income will still require a valid ITIN.
