ITIN Renewal Friction for Danish Short-Term Rental Operators
Short-term rental operators based in Denmark who previously obtained an ITIN often face renewal requirements triggered by IRS policy or non-use. Unlike U.S. residents, Danish operators typically hold an ITIN for personal tax filings related to U.S. sourced income, such as rental income from U.S. properties. The friction point arises when their existing ITIN expires, potentially impacting their ability to file U.S. tax returns accurately and on time. The IRS uses a rolling middle-digit expiration schedule, meaning ITINs expire every five years, regardless of use. Additionally, an ITIN is automatically invalidated if not used on a federal tax return for three consecutive years. For Danish operators, this means proactively monitoring their ITIN status is essential, rather than waiting for an IRS notice, which may not always be sent.
When to Renew Your ITIN
ITIN Renewal is required when your ITIN has expired. The IRS automatically invalidates ITINs that have not been used on a federal tax return for three consecutive years. Furthermore, the IRS follows a middle-digit expiration schedule; for example, ITINs ending in '70' expired in 2023, and those ending in '80' will expire in 2024. Danish short-term rental operators must check their ITIN's expiration date to avoid issues with their U.S. tax obligations. The most common scenario for renewal is when an operator needs to file a U.S. tax return (e.g., Form 1040-NR for rental income) and discovers their ITIN is no longer valid. Proactive renewal is advised, as relying solely on IRS notices like CP-48 can lead to missed deadlines, especially since not all expired ITIN holders receive such notices.
Required Documents for ITIN Renewal
To renew your ITIN, you will need specific documentation. The primary form is IRS Form W-7, with the 'Renew an Existing ITIN' box checked. You must submit a current federal tax return with your Form W-7. If you have it, your most recent ITIN acceptance letter (often called a CP-565 notice) is helpful, though not strictly mandatory if you know your ITIN. The most critical document is a valid passport. It must be original or certified by the issuing agency. If you cannot submit your original passport, you can provide certified copies of your passport from the issuing agency (e.g., the U.S. embassy or consulate in Denmark, or the passport-issuing authority in Denmark). Alternatively, you can have your identity documents verified by a Certified Acceptance Agent (CAA). Other supporting documents like birth certificates or national identity cards may be accepted if a passport is unavailable, but a passport is the preferred and most common form of identification for ITIN applications and renewals.
The ITIN Renewal Application Process
The ITIN renewal process involves submitting the correct forms and documentation to the IRS. First, complete IRS Form W-7, ensuring you check the box indicating you are renewing an existing ITIN. Attach your current U.S. federal tax return to the Form W-7. You must then decide how to submit your original identification documents or certified copies. You can mail your application package directly to the IRS ITIN Operation in Austin, Texas. However, this requires sending original documents, which carries a risk of loss or delay. A more secure and often faster method is to use a Certified Acceptance Agent (CAA). A CAA can verify your original identification documents, preventing you from having to mail them to the IRS. The typical timeline for processing an ITIN renewal through a CAA is 5–10 business days, whereas direct mailing to the IRS can take significantly longer, often several weeks or months. Your ITIN renewal application is processed alongside your tax return. Once approved, you will receive a new ITIN acceptance letter.
Common Mistakes for Danish Short-Term Rental Operators
Danish short-term rental operators often make specific errors during ITIN renewal. One common mistake is failing to submit a current federal tax return with the Form W-7. The IRS requires a tax return to process the renewal; it's not a standalone application. Another pitfall is submitting uncertified copies of identification documents. If not using a CAA, you must send original passports or certified copies from the issuing agency. Mismatched names between your Form W-7, passport, and prior IRS records can also cause delays or rejections. For instance, if your passport uses a different legal name than what's on your previous ITIN, you must provide documentation explaining the name change. Lastly, many operators in Denmark delay renewal until their ITIN has expired, only to find they cannot file their U.S. tax return, potentially incurring penalties and interest. Proactive checks are key.
Benefits of Using a Certified Acceptance Agent (CAA)
Using a Certified Acceptance Agent (CAA) streamlines the ITIN renewal process for short-term rental operators in Denmark. A CAA is an individual or entity authorized by the IRS to assist taxpayers in obtaining ITINs. As a CAA, itin.net can verify your original identification documents, such as your passport, on your behalf. This means you do not have to mail your original passport or other sensitive documents to the IRS, significantly reducing the risk of loss or theft during transit. CAAs also review your application for completeness and accuracy before submission, minimizing the chance of errors that could lead to delays or rejections. The expedited processing through a CAA, often within 5–10 business days for renewal, is a major advantage compared to the longer waiting times for direct mail applications to the IRS. This efficiency is particularly valuable for operators needing to file their U.S. tax returns promptly.
Next Steps After ITIN Renewal
Once your ITIN renewal is approved, you will receive a new ITIN acceptance letter from the IRS. This new ITIN is generally the same as your previous one, unless the IRS assigns a new number due to specific circumstances. You can now use this valid ITIN to file your current and future U.S. federal tax returns. If you operate your short-term rental business through a U.S. entity like a U.S. LLC, ensure your ITIN is correctly associated with your personal tax filings, distinct from your business filings which use an EIN. Review your tax obligations annually to stay compliant.

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.
- Ensure your current federal tax return is attached to your Form W-7; the IRS will not process a renewal without it.
- If you cannot submit your original passport, obtain certified copies from the passport-issuing authority in Denmark or your country's embassy.
- Check your ITIN's expiration status proactively rather than waiting for an IRS notice (e.g., CP-48), as notices are not always sent.
- If you have previously used a Certified Acceptance Agent (CAA), consider using one again for verification of your documents and expedited processing.
Frequently asked questions
Do I need to renew my ITIN if I haven't filed a U.S. tax return in a few years?
Yes, if your ITIN has not been used on a federal tax return for three consecutive years, it is automatically invalidated by the IRS and must be renewed before you can file again. Additionally, the IRS has a rolling middle-digit expiration schedule, so even if you've used your ITIN, it may have expired based on its number.
Can I use my Danish driver's license as identification for ITIN renewal?
The IRS prefers a valid passport for ITIN applications and renewals. While other documents like a national identity card may be accepted, a Danish driver's license is typically not sufficient on its own. Your best option is a passport or certified copies of it.
How long does ITIN renewal take for someone in Denmark?
If you use a Certified Acceptance Agent (CAA), the process typically takes 5–10 business days for document verification and submission. IRS processing times can vary but are generally longer than through a CAA. Direct mailing your application to the IRS may take several weeks to months.
What is the difference between an ITIN and an EIN for my rental business?
An ITIN (Individual Taxpayer Identification Number) is for individuals who need to file U.S. taxes but are not eligible for an SSN. An EIN (Employer Identification Number) is for business entities, such as a U.S. LLC, and is used for business tax filings and banking. You likely need both if you operate a rental business through a U.S. entity.
Do I need to be physically present in the U.S. to renew my ITIN?
No, you do not need to be physically present in the U.S. to renew your ITIN. Short-term rental operators in Denmark can complete the renewal process by mail or by working with a Certified Acceptance Agent (CAA) who can verify your documents remotely or in person if they have a local presence.
What happens if my ITIN expires and I need to file a tax return?
If your ITIN has expired and you need to file a U.S. tax return, you must renew your ITIN first. Failure to do so will result in your tax return being rejected by the IRS. This can lead to delays in processing, potential penalties, and interest on any tax due.
