Why Short-Term Rental Operators in Greece Need an ITIN
Short-term rental operators in Greece who receive income from U.S. sources, such as bookings through platforms like Airbnb or Vrbo, may require an ITIN. This is because U.S. tax law often requires non-residents earning such income to file a U.S. tax return. Without a Social Security Number (SSN), the IRS issues an ITIN to fulfill this filing obligation. For operators in Greece, this situation is particularly relevant if they have U.S.-based properties or significant bookings from U.S. residents that trigger U.S. tax reporting requirements. The process can seem daunting, but understanding the specific triggers and documentation is key.
The primary trigger for needing an ITIN in this context is the requirement to file a U.S. tax return, typically Form 1040-NR (U.S. Nonresident Alien Income Tax Return). This filing obligation arises from U.S. source income. For short-term rental operators, this income could stem from renting out a property located in the U.S. or, in some cases, income derived from U.S. persons or entities, even if the property is not physically in the U.S. It is essential to determine if your rental income qualifies as U.S. source income according to IRS regulations.
ITIN Eligibility and Filing Triggers for Greek Operators
An ITIN is required for individuals who must file a U.S. tax return but are not eligible for an SSN. For short-term rental operators in Greece, this most commonly applies when U.S. tax law dictates that their rental income is subject to U.S. taxation. This can occur if you own property within the United States and rent it out. The U.S. tax system has specific rules for foreign individuals earning income from U.S. real property.
Platforms like Airbnb and Vrbo often require hosts to provide tax identification information. If you are a Greek resident earning income through these platforms from U.S.-based properties, they may withhold U.S. taxes at source. To claim treaty benefits under the Greece-U.S. tax treaty and to file your U.S. tax return correctly, you will need an ITIN. Form 1042-S is often issued by booking platforms to report U.S. source income paid to foreign persons, and this form will typically require your ITIN for accurate reporting and tax treaty claims.
Required Documentation for Your ITIN Application
Applying for an ITIN requires submitting specific documentation to the IRS. The core form is Form W-7, Application for IRS Individual Taxpayer Identification Number. This form collects personal information necessary for the IRS to assign you a unique tax ID.
Along with Form W-7, you must provide original identification documents or certified copies from the issuing agency to prove your identity and foreign status. The most commonly accepted document is a valid passport. If you do not have a passport, other documents like a national identity card, driver's license, or birth certificate may be accepted, but a passport is preferred by the IRS. You will also need to include a copy of the U.S. tax return you are filing to claim the ITIN, or a justification for why an ITIN is needed. For example, if you are filing a 1040-NR for your rental income, a draft or filed copy of that return must accompany your Form W-7. Ensure all submitted documents are current and valid.
The ITIN Application Process and Timeline
The ITIN application process involves completing Form W-7 and gathering supporting documents. You can submit your application directly to the IRS Service Center in Austin, Texas, or use the services of a Certified Acceptance Agent (CAA). Using a CAA is generally recommended for accuracy and to avoid mailing original documents.
When you apply through a CAA, like itin.net, they verify your original identification documents and forward your application to the IRS. This process typically takes 5–10 business days from the time the CAA submits the application to the IRS for processing. If you mail your application directly to the IRS, processing times can be significantly longer, often 8–11 weeks, and you risk losing your original documents during transit. Once approved, the IRS will mail your ITIN directly to you, usually on IRS notice CP-565.
Common Mistakes for Greek Short-Term Rental Operators
Short-term rental operators in Greece often make specific mistakes when applying for an ITIN. One common error is failing to include a U.S. tax return with the Form W-7. The IRS requires proof that you have a filing obligation; simply stating you earn U.S. rental income is not enough. You must attach a complete U.S. tax return (e.g., Form 1040-NR) or a valid reason for needing the ITIN outside of immediate filing.
Another frequent pitfall is incorrect treaty claims. While Greece has a tax treaty with the U.S., claiming treaty benefits requires specific justification and correct form usage. Ensure you understand which articles of the treaty apply to your rental income and that this is correctly reflected on your tax return. Mismatched personal information between your Form W-7 and your identification documents (like a passport) is also a significant cause for rejection. Even minor discrepancies in names or dates of birth can lead to delays or denial. Lastly, sending photocopies instead of original documents or certified copies when applying directly to the IRS can result in rejection.
Benefits of Using a Certified Acceptance Agent (CAA)
Applying for an ITIN through a Certified Acceptance Agent (CAA) streamlines the process and offers distinct advantages. A CAA is an individual or entity authorized by the IRS to help applicants complete Form W-7 and, crucially, to authenticate your original identification documents. This means you do not have to mail your original passport or other vital identification to the IRS, significantly reducing the risk of loss or theft.
At itin.net, we act as a CAA. Our role is to review your application for completeness and accuracy before submitting it to the IRS. We verify your identity documents on your behalf, certifying them so the IRS can accept them without requiring you to send the originals. This verification process significantly speeds up the overall application timeline, often reducing it to the IRS's standard processing time for CAAs, which is typically 5–10 business days. This expedited service is particularly valuable for short-term rental operators who need their ITIN promptly to file their U.S. tax returns and avoid penalties.
Next Steps After Receiving Your ITIN
Once you receive your ITIN from the IRS, typically on notice CP-565, you can proceed with filing your U.S. tax return. Ensure you accurately enter your ITIN on all tax forms, including Form 1040-NR. This is critical for the IRS to process your return and any associated refunds or tax payments correctly.
For short-term rental operators in Greece, having your ITIN allows you to comply with U.S. tax obligations, claim any applicable treaty benefits, and potentially recover over-withheld taxes. If you plan to establish a U.S. business presence, such as a U.S. LLC, you may also need an EIN. Opening a U.S. bank account can further simplify managing U.S. income and expenses. Review the services offered at itin.net for ITIN applications, and consider consulting with a tax professional specializing in U.S. expat or non-resident taxation to ensure full compliance.

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 application is complete before submission; missing information or attachments will delay processing.
- If you are filing jointly with a spouse who also needs an ITIN, submit separate Form W-7 applications for each individual.
- Keep copies of all documents submitted with your ITIN application for your personal records.
- Understand the specific U.S. tax implications of your rental income; consult a tax professional if unsure about source rules or treaty benefits.
Frequently asked questions
Do I need an ITIN if my short-term rental income in the U.S. is below a certain threshold?
The requirement for an ITIN is generally tied to the obligation to file a U.S. tax return, not solely a specific income threshold. If U.S. tax law dictates your rental income is taxable in the U.S., you will likely need an ITIN to file, regardless of the exact amount, especially if U.S. taxes were withheld.
Can I use my Greek tax identification number instead of an ITIN?
No, your Greek tax identification number is not a substitute for a U.S. ITIN. The ITIN is a U.S. federal tax identification number required for U.S. tax purposes. You will need an ITIN to file U.S. tax returns and comply with IRS regulations.
How long does it take to get an ITIN?
When applying through a Certified Acceptance Agent (CAA) like itin.net, the typical processing time is 5–10 business days from submission to the IRS. If you mail your application directly to the IRS, it can take 8–11 weeks or longer.
What happens if I don't get an ITIN when I should have?
Failure to obtain an ITIN when required can result in penalties from the IRS, including failure-to-file and failure-to-pay penalties. It can also prevent you from claiming treaty benefits or recovering over-withheld taxes. The IRS may also withhold tax at a higher rate on your U.S. source income.
Can I use the Greece-U.S. tax treaty to avoid needing an ITIN?
The Greece-U.S. tax treaty can help reduce or eliminate U.S. tax on your rental income, but it does not eliminate the need for an ITIN if you have a U.S. filing obligation. You generally need an ITIN to claim treaty benefits on your U.S. tax return (Form 1040-NR).
What is the difference between an ITIN and an EIN?
An ITIN (Individual Taxpayer Identification Number) is for individuals who need to file U.S. taxes but cannot get an SSN. An EIN (Employer Identification Number) is a tax ID for businesses, partnerships, and corporations. Short-term rental operators might need both: an ITIN for their personal tax filings and potentially an EIN if they operate as a business entity like a U.S. LLC.
