Why Croatia-Based Short-Term Rental Operators Need ITIN Renewal
Short-term rental operators based in Croatia who previously held an Individual Taxpayer Identification Number (ITIN) may find themselves needing to renew it. This is distinct from first-time applicants. The primary drivers for renewal are either the ITIN's expiration due to non-use on a federal tax return for three consecutive years, or because the IRS has implemented its rolling expiration schedule based on the middle digits of the ITIN. As a Croatia-based operator, you likely use your ITIN for personal U.S. tax obligations related to your rental income, even if your business entity (like a U.S. LLC) has its own Employer Identification Number (EIN).
Failure to renew an expired ITIN can lead to issues when filing subsequent U.S. tax returns, potentially causing delays or rejections. For short-term rental operators, this could impact your ability to claim deductions, report income accurately, or comply with U.S. tax laws, which are essential for maintaining your investment and business operations. Proactively checking your ITIN status is far more efficient than waiting for IRS notices like the CP-48, which may not always be issued. The Croatia–U.S. tax treaty in force as of 2025 may affect certain aspects of your U.S. tax liability, but it does not negate the requirement to maintain a valid ITIN for reporting purposes if you have U.S.-sourced income.
ITIN Renewal Triggers for Rental Operators
Your ITIN requires renewal if it has expired. The IRS uses a rolling expiration schedule where ITINs expire if not used on a federal tax return for three consecutive tax years. Additionally, the IRS periodically cancels ITINs based on their middle digits. For example, ITINs with the middle digits 70-82 expired starting in 2021, and those with 83-92 expired starting in 2022. You can check your ITIN's status directly with the IRS or through a Certified Acceptance Agent (CAA).
For short-term rental operators, this renewal is typically triggered by the need to file a U.S. tax return. If you operate your rental business through a U.S. LLC, you might have an EIN for business purposes, but your personal share of the income or other personal tax obligations will require your ITIN. Even if your LLC is disregarded for tax purposes, the income flows to your personal return, necessitating a valid ITIN. If you haven't filed a U.S. federal tax return using your ITIN in the last three years, or if its middle digits fall within an IRS-specified expiration range, renewal is necessary.
Required Documents for ITIN Renewal
To renew your ITIN, you will need to submit Form W-7, Application for IRS Individual Taxpayer Identification Number, with the 'Renew an Existing ITIN' box checked. Along with the completed W-7, you must provide original or certified copies of specific supporting documents. The most critical document is proof of your foreign status and identity. This is typically your valid passport.
If you have a previous ITIN notice from the IRS, such as a CP-565, including it can expedite the process, although it's not strictly mandatory if you know your ITIN. You will also need your current federal tax return to attach to the W-7 application. Ensure all documents are current and accurate. If your name has changed since your last ITIN application, you will need to provide legal documentation to support the change, such as a marriage certificate or court order. The IRS requires these documents to verify your identity and foreign status.
The ITIN Renewal Application Process
The ITIN renewal process begins with completing Form W-7, ensuring you check the box indicating you are renewing an existing ITIN. You must then gather your supporting identification documents, typically your passport, and your current federal tax return. There are two primary methods to submit your application: by mail directly to the IRS or through a Certified Acceptance Agent (CAA).
Submitting directly to the IRS involves mailing your original identification documents, which can take several weeks to be returned. The processing time for the ITIN application itself can range from 7 to 14 weeks, especially during peak tax season. Alternatively, using a CAA like itin.net offers a more streamlined experience. A CAA can verify your original identification documents and forward your application to the IRS, often resulting in a faster turnaround time. The typical timeline through a CAA is 5–10 business days for document verification and submission, with the IRS processing typically taking an additional 4–6 weeks.
Common Mistakes for Croatian Short-Term Rental Operators
Short-term rental operators based in Croatia often make specific mistakes when renewing their ITIN. One common error is failing to proactively check their ITIN status. Many wait until they receive a CP-48 notice, which can be too late and may not even be sent to all individuals whose ITINs have expired. Relying on the CP-48 notice is a significant risk.
Another frequent pitfall is submitting incomplete or inaccurate documentation. This includes failing to provide a complete tax return or using expired identification. Mismatched name fields between your Form W-7, passport, and any prior IRS correspondence are also a major cause of rejection. For those operating through a U.S. LLC, ensure you correctly differentiate between your business filings (using an EIN) and your personal tax obligations (requiring your ITIN). Incorrectly reporting income or failing to account for U.S. tax treaty provisions relevant to your specific situation can also lead to complications. Confirming the specific tax treaty articles applicable to your rental income and residency status in Croatia is crucial.
Benefits of Using a Certified Acceptance Agent (CAA)
A Certified Acceptance Agent (CAA) is an individual or entity authorized by the IRS to assist taxpayers in obtaining ITINs. As a CAA, itin.net can significantly simplify the ITIN renewal process for short-term rental operators in Croatia. The primary benefit is that CAAs can authenticate your original identification documents, such as your passport. This means you do not have to mail your original documents to the IRS, reducing the risk of loss or delay.
When you apply through a CAA, we review your Form W-7 and supporting documentation for completeness and accuracy before forwarding them to the IRS. This pre-screening helps minimize errors that could lead to application rejection. The typical processing time for an ITIN renewal through a CAA is considerably faster than applying directly to the IRS, often within 5–10 business days for the initial verification and submission phase. This expedited handling allows you to obtain your renewed ITIN more quickly, enabling timely tax filings.
Next Steps After ITIN Renewal
Once your ITIN renewal is approved by the IRS and you receive your new ITIN or confirmation of your existing one, you can proceed with filing your U.S. federal tax return. Ensure you use the correct ITIN on all relevant tax forms, including Form 1040-NR if you are a non-resident alien. If you operate your short-term rental business through a U.S. LLC, remember to use your EIN for business-related filings and your renewed ITIN for your personal tax obligations.
Accurate reporting of your rental income and any applicable deductions is vital. If you have questions about your U.S. tax obligations as a Croatia-based short-term rental operator, or if you need assistance with the renewal process, consulting with a qualified tax professional is recommended.

Practical tips
- Use the same legal name across Form W-7, your passport, and any prior IRS correspondence; mismatched name fields are a common reason for rejection.
- Proactively check your ITIN status annually, especially if you haven't filed a U.S. tax return in three years, rather than waiting for an IRS notice.
- Ensure your passport is valid and has sufficient remaining validity to be accepted by the IRS as proof of identity and foreign status.
- If you have a U.S. LLC, ensure you clearly distinguish between your business filings (using an EIN) and your personal tax obligations (requiring your ITIN).
- Double-check that the correct 'Renew an Existing ITIN' box is selected on Form W-7; selecting the wrong option will lead to rejection.

How long does ITIN renewal take for short-term rental operators in Croatia?
The typical timeline for ITIN renewal through a Certified Acceptance Agent (CAA) like itin.net is 5–10 business days for verification and submission, with IRS processing taking an additional 4–6 weeks. Applying directly to the IRS can take significantly longer, potentially 7–14 weeks or more for processing.
Do I need an ITIN if my short-term rental business has an EIN?
Yes, if you are a non-resident alien receiving U.S. rental income, you generally need an ITIN for your personal U.S. tax return, even if your business entity has an EIN. The EIN is for the business entity, while the ITIN is for your personal identification with the IRS.
Can I renew my ITIN if I haven't filed a U.S. tax return in years?
Yes, if your ITIN has expired due to non-use for three consecutive years or due to the IRS's rolling expiration schedule, you can renew it by filing Form W-7 with your current federal tax return. You will need to demonstrate your need for an ITIN.
What happens if my ITIN expires and I don't renew it?
If your ITIN expires and you don't renew it, you may face difficulties filing your U.S. tax returns, potentially leading to delays, rejections, or inability to claim deductions. This can impact your compliance with U.S. tax laws.
Do I need to send my original passport to the IRS for ITIN renewal?
Not necessarily. If you use a Certified Acceptance Agent (CAA) like itin.net, we can verify your original documents, such as your passport, and send copies to the IRS. This avoids the risk of mailing your original passport.
How does the Croatia–U.S. tax treaty affect my ITIN renewal?
The Croatia–U.S. tax treaty primarily affects withholding rates and taxation of certain types of income. However, it does not eliminate the need for a valid ITIN if you are required to file a U.S. tax return. You must still maintain a current ITIN for reporting purposes.
