Croatia-based consultants face unique ITIN requirements
Independent consultants in Croatia billing U.S. clients often encounter situations where a U.S. Individual Taxpayer Identification Number (ITIN) becomes necessary. While U.S. tax law generally applies to income earned within the U.S., the specifics for consultants operating internationally can be complex. The primary trigger for needing an ITIN is the requirement to file a U.S. tax return, even if you have no physical presence in the United States. This is common for consultants who receive payments directly from U.S. entities or individuals. Without an ITIN, you may face significant backup withholding on your U.S. source income, which can be as high as 30%. The Croatia–U.S. tax treaty may offer some relief, but claiming treaty benefits typically requires filing a U.S. tax return, thus necessitating an ITIN. Furthermore, establishing a U.S. business entity, such as a U.S. LLC, is often recommended for liability protection and tax efficiency, and this can also lead to U.S. tax filing obligations requiring an ITIN. The goal is to ensure compliance while minimizing unnecessary tax burdens and withholding.
When you absolutely need an ITIN
An ITIN is required if you must file a U.S. tax return but cannot obtain a Social Security Number (SSN). For consultants in Croatia, this scenario most commonly arises when you earn U.S. source income that is not subject to adequate withholding at the source. This includes payments for services performed remotely for U.S. clients. Another trigger is if you are required to file informational returns, such as Form 5472, which applies to foreign-owned U.S. entities like a U.S. LLC that engages in certain transactions with its foreign owner. If you are claiming tax treaty benefits on U.S. source income, you will generally need to file a U.S. tax return (often Form 1040-NR, U.S. Nonresident Alien Income Tax Return) to claim those benefits, and this necessitates an ITIN. The IRS issues ITINs to individuals who have a U.S. tax filing obligation. Without an ITIN, withholding agents may be forced to withhold at the maximum backup rate, impacting your net income.
Required documentation for your ITIN application
Applying for an ITIN involves submitting a completed Form W-7, Application for IRS Individual Taxpayer Identification Number, along with original or certified copies of identity and foreign status documents. The most commonly accepted document proving identity and foreign status is your valid passport. If you do not have a passport, other documents can be used, such as a national identity card along with a birth certificate, or a driver's license. All submitted documents must clearly show your name, photograph, current address, date of birth, and expiration date. You must also include the U.S. federal tax return that you are required to file. For consultants in Croatia, this is typically Form 1040-NR. Ensure the name on your Form W-7 exactly matches the name on your supporting identification documents and your tax return. Discrepancies are a primary reason for application rejection. If you are applying under an exception category, such as claiming treaty benefits, ensure you have documentation supporting that claim.
Step-by-step ITIN application process
The ITIN application process begins with gathering your required documents: a completed Form W-7, your original tax return, and original or certified copies of your identification documents. You have several options for submitting your application. You can mail all documents directly to the IRS in Austin, Texas. However, this method requires you to send original identification documents, which can take several months for the IRS to process and return. A more efficient method is to apply through a Certified Acceptance Agent (CAA). A CAA, like itin.net, can verify your original documents and forward your application to the IRS on your behalf. This avoids mailing your original passport or other vital documents. The typical timeline when applying through a CAA is 5–10 business days for the verification process and submission, with IRS processing taking an additional 4–11 weeks. You will receive your ITIN via mail in the form of a notice from the IRS, typically CP-565.
Common ITIN mistakes for Croatia-based consultants
Consultants in Croatia often make specific errors on their ITIN applications. A frequent issue is failing to include a complete U.S. federal tax return with the Form W-7. The IRS will not process an ITIN application without an accompanying tax return, unless you qualify for a specific exception (which is rare). Another common pitfall is submitting photocopies of identification documents instead of originals or certified copies. The IRS requires original documents to verify your identity and foreign status. Mismatched names between your Form W-7, passport, or other identification are also a significant problem leading to rejection. If you are claiming benefits under the Croatia–U.S. tax treaty, ensure you are correctly referencing the relevant treaty article and meeting all associated conditions. Incorrectly claiming treaty benefits without proper substantiation can lead to denial of the claim and potential penalties. Finally, ensure your tax return is accurate and complete; errors can cause delays or rejection of both the return and the ITIN application.
Benefits of using a Certified Acceptance Agent (CAA)
Applying for an ITIN through a Certified Acceptance Agent (CAA) offers distinct advantages, particularly for consultants managing international affairs. The primary benefit is that a CAA can authenticate your original identification documents, such as your passport, and then send certified copies to the IRS. This means you do not have to mail your original, irreplaceable documents directly to the IRS, mitigating the risk of loss or delay in their return. CAAs are trained and authorized by the IRS to help taxpayers complete Form W-7 and verify documentation. This process significantly streamlines the application, reducing the chances of common errors that lead to rejections. itin.net, as a CAA, provides a secure and efficient pathway for consultants in Croatia to obtain their ITIN without the anxiety of mailing sensitive originals. The typical processing time via a CAA is also generally faster for the initial submission phase.
Next steps after obtaining your ITIN
Once you receive your ITIN from the IRS, typically via notice CP-565, you can finalize your U.S. tax filing obligations. If you filed your tax return with your ITIN application, you should ensure it is processed correctly. If you did not file a return with your initial Form W-7, you will need to file it promptly to avoid potential penalties. For consultants who have established or plan to establish a U.S. entity like a U.S. LLC, your ITIN is crucial for the entity's tax filings, such as Form 5472. Obtaining a U.S. bank account may also be a subsequent step, though some banks require an SSN or a U.S. business address.

Practical tips
- Use the exact same legal name on your Form W-7, passport, and any prior IRS correspondence to prevent mismatches.
- Ensure your submitted U.S. tax return is complete and accurate; incomplete returns are a primary reason for ITIN application rejection.
- When claiming tax treaty benefits, precisely cite the relevant article of the Croatia–U.S. tax treaty and confirm you meet all criteria.
- Avoid mailing original identification documents to the IRS; use a Certified Acceptance Agent (CAA) to have your documents verified instead.
- If you are setting up a U.S. LLC, ensure you have applied for and received your ITIN before filing Form 5472, as the ITIN is required for that filing.
Frequently asked questions
Do I need an ITIN if I'm a consultant in Croatia and my U.S. client pays me via Wise?
If your client is a U.S. entity or individual and the payment is for services, it is considered U.S. source income. Even if paid through a third-party platform like Wise, you likely have a U.S. tax filing obligation. You will need an ITIN to file your U.S. tax return (e.g., Form 1040-NR) to report this income and potentially claim benefits under the Croatia–U.S. tax treaty. Without an ITIN, your client may be required to withhold up to 30% of your payment.
How long does it take to get an ITIN through itin.net?
The process through itin.net, a Certified Acceptance Agent, typically takes 5–10 business days for us to verify your documents and submit your application to the IRS. The IRS then processes the application, which can take an additional 4–11 weeks. You will receive your ITIN directly from the IRS.
Can I use my Croatian national ID card instead of a passport for my ITIN application?
If you do not have a valid passport, you can use other identity documents. For ITIN applications, a national identity card combined with a birth certificate may be acceptable. However, a valid passport is the preferred and most straightforward document for proving both identity and foreign status to the IRS. Confirm the exact requirements with a Certified Acceptance Agent.
What happens if my ITIN application is rejected?
If your ITIN application is rejected, the IRS will send you a letter explaining the reason. Common reasons include an incomplete Form W-7, missing or unacceptable identification documents, or an incomplete U.S. tax return. You will need to correct the issues identified and resubmit your application. Using a Certified Acceptance Agent can help minimize the risk of rejection by ensuring your application is complete and accurate before submission.
Do I need to renew my ITIN?
ITINs do not expire unless they are not used on a federal tax return for three consecutive tax years. The IRS may also issue new ITINs in batches. If your ITIN has expired or you need to renew it, you will follow a similar process to the initial application, submitting Form W-7 and supporting documentation.
Should I form a U.S. LLC or get an ITIN first?
For consultants in Croatia, it is generally advisable to establish a U.S. LLC first, and then obtain an ITIN. The LLC will need an Employer Identification Number (EIN), which can be obtained using your ITIN or by designating a responsible party. However, if your primary need for an ITIN is to file a personal tax return (e.g., Form 1040-NR), you may apply for the ITIN first. If the LLC requires you to file Form 5472, you will need an ITIN for that filing. Consulting with a tax professional familiar with U.S. international tax law is recommended to determine the optimal sequence for your specific situation.
