Why Airbnb Hosts in Denmark Need ITIN Renewal
As an Airbnb host in Denmark with U.S. rental properties, you generate U.S. source income. This income requires U.S. tax filings, typically Form 1040-NR, for which you need an Individual Taxpayer Identification Number (ITIN). If your existing ITIN has expired, you must renew it to comply with U.S. tax laws. Non-resident hosts in Denmark face unique challenges, including navigating the U.S. tax system from abroad and understanding how treaty provisions might affect their tax liability. Proactive ITIN renewal prevents disruptions to your U.S. tax obligations and ensures you can continue reporting your rental income accurately.
Your ITIN typically expires if you haven't used it on a federal tax return for three consecutive years, or if the IRS initiates an automatic expiration based on a rolling schedule tied to the middle digits of your ITIN. For Airbnb hosts, this often means renewing your ITIN to file your annual U.S. income tax return (Form 1040-NR). The IRS sends notices like CP-48 to inform taxpayers of expiring ITINs, but relying solely on these notices is risky. Many individuals do not receive them, leading to unexpected issues when filing their taxes.
Eligibility and Triggers for ITIN Renewal
You must renew your ITIN if it has expired and you need to file a U.S. federal tax return. The IRS uses a rolling expiration schedule based on the middle digits of your ITIN. Additionally, an ITIN is automatically invalidated if you do not claim it on a U.S. federal tax return for three consecutive tax years. For Airbnb hosts in Denmark, the primary trigger for ITIN renewal is the requirement to file a U.S. tax return (Form 1040-NR) reporting income from your U.S. property.
The U.S. tax treaty with Denmark may offer benefits, but it does not exempt you from the requirement to file U.S. taxes on U.S. source income. Therefore, maintaining a valid ITIN is essential for compliance. If you are unsure about your ITIN's status, you can check it proactively on the IRS website or by contacting a Certified Acceptance Agent (CAA). Waiting until the tax deadline or until you receive an IRS notice like CP-48 can lead to significant delays and potential penalties.
Required Documents for ITIN Renewal
To renew your ITIN, you will need to submit IRS Form W-7 with the 'Renew an Existing ITIN' box checked. You must also provide original identification documents or certified copies from the issuing agency. The most commonly accepted primary identification document is your valid passport.
Your passport must be current and contain your full legal name, photograph, and expiration date. If you cannot submit your original passport, you can provide certified copies of your birth certificate, national identification card, or other acceptable documents listed by the IRS. An original ITIN notice (Form CP-565 or CP-575) is helpful if you have it, but not strictly required if you know your ITIN. You will also need to include a current federal tax return with your Form W-7 application. This tax return demonstrates why you need a valid ITIN for U.S. tax purposes.
The ITIN Renewal Application Process
The ITIN renewal process involves completing Form W-7 and gathering your supporting documentation. You have two primary options for submitting your application: mail it directly to the IRS or apply through a Certified Acceptance Agent (CAA). Applying through a CAA like itin.net can significantly streamline the process and reduce the risk of errors.
If you mail your application directly to the IRS, you will need to send original identification documents or certified copies, which the IRS will keep and return by mail. This can take several weeks. Using a CAA involves presenting your original documents to them. The CAA will verify your identity and review your application package before forwarding it to the IRS. This verification step means you do not have to mail your original documents to the IRS, and the CAA can often expedite the process. The typical timeline for ITIN renewal through a CAA is 5–10 business days for the initial processing, with the IRS issuing the new ITIN within 7-11 weeks. The IRS processes ITIN applications year-round.
Common Mistakes for Danish Airbnb Hosts
Airbnb hosts in Denmark often make specific errors when renewing their ITIN. A common issue is inconsistent name usage. Ensure the name on your Form W-7 exactly matches your passport and any prior IRS correspondence. Even slight discrepancies can cause delays or rejection.
Another frequent mistake is failing to include a complete and accurate U.S. federal tax return with your Form W-7. This tax return must be the one for which you need the ITIN. For example, if you are filing a 1040-NR for the current tax year, that is the return you must submit. Missing or incorrect tax return information is a primary reason for application rejection. Ensure all sections of Form W-7 are completed accurately, paying close attention to fields like foreign tax identification number if applicable, and your U.S. address.
Benefits of Using a Certified Acceptance Agent (CAA)
Applying for ITIN renewal through a Certified Acceptance Agent (CAA) offers distinct advantages for Airbnb hosts in Denmark. A CAA is authorized by the IRS to help taxpayers obtain ITINs. They can authenticate your original identification documents, meaning you do not have to mail sensitive originals to the IRS. This significantly reduces the risk of loss or theft of your passport or other vital documents.
Furthermore, CAAs are trained to ensure your application is complete and accurate, minimizing the chances of rejection. They can often expedite the initial processing of your application. At itin.net, we are a CAA service dedicated to simplifying the ITIN renewal process for individuals like you. Our expertise ensures your application meets IRS standards, saving you time and potential frustration. This service typically costs $397 for the renewal package.
Next Steps After ITIN Renewal
Once your ITIN renewal is approved by the IRS, you will receive a new ITIN. This new ITIN is crucial for filing your U.S. federal tax returns for the current and future tax years. You should keep this new ITIN in a safe place and update any records that may have your old ITIN.
If you are considering forming a U.S. LLC for your rental property business, you will also need an EIN. An EIN is separate from an ITIN and is used for business tax purposes. Many non-residents also find it beneficial to open a U.S. bank account to manage their U.S. income and expenses more efficiently.

Practical tips
- Use the same legal name across Form W-7, your passport, and any prior IRS correspondence; mismatched name fields are a common rejection reason.
- Ensure your submitted U.S. federal tax return is complete and accurate, as it is the primary document proving your need for an ITIN.
- Check your ITIN status proactively on the IRS website or via a CAA rather than waiting for a CP-48 notice, which may not be received.
- When applying through a CAA, present original identification documents; the CAA will verify them, and you retain possession of your originals.
- Keep a copy of your submitted Form W-7 and all supporting documents for your records, along with the new ITIN once issued.
