ITIN Application Friction for Remote Employees in Greece

Remote employees of U.S. companies based in Greece typically encounter the need for an ITIN when U.S. source income requires a U.S. tax filing. This often arises from payment structures that necessitate a W-8BEN form submission to the U.S. payer, which in turn may require an ITIN for accurate tax withholding and reporting. Unlike U.S. residents or citizens, individuals in Greece do not have access to a Social Security Number (SSN), making the ITIN the sole identification number for U.S. tax purposes. The primary friction point is understanding the specific U.S. tax obligations triggered by their employment arrangement and ensuring the ITIN application aligns with IRS requirements, especially concerning documentation and the correct treaty claims under the Greece-U.S. tax treaty.

When an ITIN is Required for Remote Employees in Greece

An ITIN becomes mandatory for remote employees in Greece when they receive U.S. source income that is subject to U.S. income tax reporting. This commonly includes payments for services performed while working remotely for a U.S. company, especially if the company classifies the individual as an independent contractor and requires them to complete a Form W-8BEN. This form is used to certify foreign status and claim treaty benefits. Without an ITIN, the U.S. payer may be required to withhold taxes at the highest rate, or the individual may face difficulties in filing their U.S. tax return (often Form 1040-NR for non-resident aliens). Some U.S. companies may also require an ITIN for internal compliance or to facilitate direct deposit of payments, though this is less common than tax reporting requirements. The Greece-U.S. tax treaty may offer reduced withholding rates, but claiming these benefits on Form W-7 typically necessitates having an ITIN.

Required Documents for ITIN Application

To apply for an ITIN, you must submit Form W-7, Application for IRS Individual Taxpayer Identification Number. This form requires your full legal name, foreign address, and U.S. taxpayer identification number (if applicable, though usually not for initial applicants). Crucially, you must provide original identification documents or certified copies from the issuing agency. The most commonly accepted primary identification document is a valid passport. If you do not have a passport, other documents like a national identification card, birth certificate, or foreign driver's license may be accepted, but they must be submitted in combination with other supporting documents to prove identity and foreign status. A copy of your U.S. tax return, for which the ITIN is needed, must also be included with your Form W-7 application, unless you qualify for a special exception. For remote employees in Greece, ensuring your passport is current and accurately reflects your legal name is vital.

The ITIN Application Process and Timeline

The application process for an ITIN involves completing Form W-7 and gathering supporting identification documents and a U.S. tax return. You have two primary options for submitting your application: mail it directly to the IRS or use a Certified Acceptance Agent (CAA). Mailing directly to the IRS means sending your original identification documents, which can take several weeks to be returned. The IRS processing time for ITIN applications submitted directly can range from 4 to 11 weeks, depending on the season and volume of applications. Alternatively, using a Certified Acceptance Agent (CAA) like itin.net allows you to submit your application without mailing your original documents. The CAA verifies your identity documents and forwards your application to the IRS. This method typically speeds up the process, with the IRS issuing the ITIN in 5–10 business days after the application is received by the IRS. The CAA also handles the initial document verification, reducing the risk of rejection due to documentation errors.

Common Mistakes for Remote Employees in Greece

Remote employees in Greece often make specific errors on their Form W-7 applications. One common pitfall is incorrectly claiming benefits under the Greece-U.S. tax treaty without a clear understanding of the applicable article and withholding requirements; this can lead to application rejection. Another mistake is failing to include a complete and accurate U.S. tax return with the Form W-7, as the ITIN is usually tied to a filing requirement. Mismatched names between your identification documents (like your passport) and Form W-7 are frequent causes for denial. Furthermore, some individuals in Greece may mistakenly believe an EIN (Employer Identification Number) is appropriate for their situation, when an ITIN is actually required for individual tax identification. Ensure you are applying for the correct tax identification number.

Benefits of Using a Certified Acceptance Agent (CAA)

Utilizing a Certified Acceptance Agent (CAA), such as itin.net, streamlines the ITIN application process for remote employees in Greece. A CAA acts as an intermediary between you and the IRS. They are authorized by the IRS to verify your original identification documents, meaning you do not have to mail your passport or other vital paperwork directly to the IRS. This significantly reduces the risk of losing your original documents during transit. The CAA also performs a pre-check of your Form W-7 and supporting documentation for completeness and accuracy, which helps to prevent common errors that can delay or derail your application. This verification process by the CAA often results in a faster processing time by the IRS compared to direct submissions, typically yielding your ITIN within 5–10 business days of the IRS receiving the application.

Next Steps After ITIN Application

Once you receive your ITIN, typically via mail from the IRS (IRS letter CP-565 or CP-575), you can use it for all future U.S. tax filings. If your employment situation changes or your U.S. income sources evolve, you may need to update your tax information with your U.S. employer or file amended tax returns. For remote employees in Greece, this means ensuring your Form W-8BEN is up-to-date with your U.S. payer, reflecting your correct ITIN and any applicable treaty benefits. If you are considering establishing a U.S. business entity like a U.S. LLC, you would pursue an EIN instead of an ITIN. For individuals who need assistance with their ITIN application or have complex tax situations, consulting with a specialist is recommended.

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 reason.
  • Ensure your passport is valid and has at least six months of validity remaining beyond your application date.
  • If claiming tax treaty benefits, carefully review Article X of the Greece-U.S. tax treaty applicable to your income type before completing Form W-7.
  • When applying through a Certified Acceptance Agent (CAA), be prepared to provide your original identification documents for verification, not photocopies.
  • Keep a copy of your submitted Form W-7 and all supporting documents for your records, as the IRS may request them later.

Frequently asked questions

Can I use my Greek tax identification number instead of an ITIN?

No, your Greek tax identification number is only for tax purposes in Greece. The IRS requires a U.S. Individual Taxpayer Identification Number (ITIN) for individuals who need to file U.S. taxes but do not have a Social Security Number (SSN).

How long does it take to get an ITIN if I'm in Greece?

If you apply through a Certified Acceptance Agent (CAA) like itin.net, the IRS typically processes the ITIN in 5–10 business days after receiving the application. Applying directly to the IRS by mail can take 4–11 weeks.

Do I need a U.S. address to apply for an ITIN?

You need to provide a foreign address on Form W-7, which would be your address in Greece. You can also provide a U.S. address if you have one (e.g., a friend or relative's address) to receive mail, but it is not mandatory if you have a foreign address.

What if my passport has expired?

An expired passport is generally not accepted as a primary identification document for an ITIN application. You must provide a valid, unexpired passport or a combination of other acceptable identification documents.

Can I use my ITIN to open a U.S. bank account?

While an ITIN can sometimes be used to open a U.S. bank account, many banks require a Social Security Number (SSN) or have specific policies for ITIN holders. It's best to check with the specific bank, such as Mercury, Relay, or Brex, about their requirements for ITIN holders.

What is the difference between an ITIN and an EIN?

An ITIN is for individuals who must file U.S. taxes but cannot obtain an SSN. An EIN (Employer Identification Number) is for businesses, corporations, partnerships, and other entities, obtained by filing Form SS-4.
