Why remote employees in Serbia need an ITIN

As a remote employee in Serbia working for a U.S. company, you may encounter situations requiring you to obtain an Individual Taxpayer Identification Number (ITIN). This is typically triggered when the U.S. company needs to report payments made to you to the IRS, especially if you are classified as an independent contractor rather than a direct employee. Without an ITIN, the company may be forced to withhold taxes at the highest U.S. rate, impacting your net earnings. The U.S. tax system requires individuals receiving U.S. source income or needing to file a U.S. tax return to have a tax identification number. For non-U.S. citizens and residents without a Social Security Number (SSN), the ITIN serves this purpose. For those in Serbia, this often arises when your U.S. client or employer needs your tax identification for their own reporting obligations, such as under IRS Form W-8BEN or similar documentation, or if you are required to file a U.S. tax return yourself (e.g., Form 1040-NR).

When an ITIN is required for your situation

You will generally need an ITIN if you are a Serbian resident receiving U.S. income and are not eligible for an SSN. This commonly includes independent contractors working remotely for U.S. companies who are paid directly. The U.S. company's payroll or accounts payable department will often request your ITIN to correctly report payments on forms like Form 1099-NEC (for non-employees) or to comply with W-8BEN requirements, which certify your foreign status and claim any applicable tax treaty benefits. If you are required to file a U.S. tax return, such as Form 1040-NR, you must have an ITIN. Even if your U.S. client is withholding taxes at a rate determined by the former Yugoslavia–U.S. tax treaty, having an ITIN facilitates accurate reporting and avoids potentially higher withholding rates. Some U.S. companies may also require an ITIN for internal compliance, to ensure all payments to foreign individuals are properly documented and reported.

Required documents for your ITIN application

To apply for an ITIN, you must complete and submit IRS Form W-7. This form requires specific identifying information and supporting documentation to verify your identity and foreign status. The most commonly accepted primary identification document is your valid passport. If you do not have a passport, other documents like a birth certificate, national identity card, or driver's license may be considered, but a passport is strongly preferred by the IRS. In addition to a photo ID, you will need to provide a U.S. federal tax return (unless you qualify for an exception, such as being a student or teacher claiming treaty benefits, which requires a different process). If you have any U.S. visa documentation, it should also be included. All documents submitted to the IRS must be originals or certified copies from the issuing agency. The IRS will review these documents and return them to you, typically within 60 days of receipt.

The ITIN application process and timeline

Applying for an ITIN involves submitting Form W-7 along with original or certified copies of your identification documents and your U.S. tax return to the IRS. You can submit your application by mail directly to the IRS in Austin, Texas, or through an authorized IRS Certified Acceptance Agent (CAA). The IRS typically processes ITIN applications within 5–10 business days when submitted through a CAA. If you mail your application directly to the IRS, the processing time can be significantly longer, often taking several weeks or even months, especially during peak tax seasons. The IRS will issue you an ITIN in a notice called CP-565. If your application is rejected, you will receive a notice explaining the reasons, such as missing documentation or an incomplete Form W-7. It's important to track your application status if you mailed it directly, or to confirm with your CAA about their process for updates.

Common mistakes for remote workers in Serbia

Remote employees in Serbia often make specific errors on their Form W-7 applications. One common mistake is failing to include a complete U.S. tax return. The IRS expects a filed tax return with your Form W-7, unless you meet specific exceptions. Another frequent issue is mismatched legal names across your identification documents and the Form W-7. Ensure the name on your passport exactly matches the name you enter on the W-7. Incorrectly claiming treaty benefits is also a pitfall; while Serbia inherits the former Yugoslavia–U.S. tax treaty, you must correctly identify the treaty article and withholding rate applicable to your specific income type. Finally, some individuals mistakenly believe they can use an EIN (Employer Identification Number) instead of an ITIN for personal tax filing; an EIN is for businesses, while an ITIN is for individuals. Ensure you are applying for the correct tax ID for your situation.

How the Certified Acceptance Agent (CAA) path helps

Using a Certified Acceptance Agent (CAA) like itin.net simplifies the ITIN application process and significantly speeds up processing times. A CAA is an individual or entity authorized by the IRS to help applicants obtain ITINs. When you apply through a CAA, they verify your original identification documents and forward your application to the IRS on your behalf. This means you do not have to mail your original passport or other vital documents, as the CAA authenticates them and returns them to you immediately. This verification process by a trusted agent reduces the risk of documents being lost or delayed in the mail. The IRS prioritizes applications submitted by CAAs, resulting in the faster 5–10 business day processing time. This expedited service is invaluable for remote employees who need their ITIN quickly for tax filing or employer compliance.

Next steps after obtaining your ITIN

Once you receive your ITIN from the IRS via notice CP-565, you can use it for all future U.S. tax filings and reporting. If you are an independent contractor, provide your ITIN to your U.S. client or employer so they can update their records and correctly report payments. If you needed the ITIN to file a U.S. tax return, ensure you complete and submit that return promptly. For those working remotely for U.S. companies, an ITIN can also be a stepping stone towards other U.S. financial services, such as opening a U.S. bank account (though requirements vary by bank). Consider consulting with a tax professional to ensure all your U.S. tax obligations are met. If you are setting up a U.S. business entity like a U.S. LLC, an ITIN might be necessary for certain aspects of the setup or compliance, such as filing Form 5472.

Practical tips

  • Ensure the legal name used on your Form W-7 precisely matches your passport or other primary identification document.
  • Include a complete and accurate U.S. federal tax return with your Form W-7, unless you qualify for a specific exception verified by a CAA.
  • Carefully review the former Yugoslavia–U.S. tax treaty provisions applicable to your income type before claiming treaty benefits on Form W-7.
  • Do not mail original identification documents to the IRS if applying through a Certified Acceptance Agent; the CAA will verify and return them.
  • If you are an independent contractor, provide your ITIN to your U.S. client promptly after receiving it to avoid potential backup withholding.

Frequently asked questions

Can I use my Serbian passport to apply for an ITIN?

Yes, a valid Serbian passport is the preferred primary identification document for your ITIN application. The IRS requires original or certified copies of your identification to verify your identity and foreign status.

How long does it take to get an ITIN through itin.net?

When you apply through itin.net as a Certified Acceptance Agent (CAA), the IRS processing time for your ITIN application is typically 5–10 business days. This is significantly faster than mailing directly to the IRS.

What if my name has changed since my passport was issued?

Do I need to file a U.S. tax return to get an ITIN?

Generally, yes. You must submit a U.S. federal tax return with your Form W-7. However, there are exceptions for certain individuals, such as those claiming tax treaty benefits on passive income, which can be handled through a CAA without a filed tax return.

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

In many cases, yes. Your ITIN can be used to open a U.S. bank account with certain U.S. financial institutions. However, requirements vary by bank, and some may still prefer a Social Security Number or have specific policies regarding foreign nationals.

What happens if my ITIN application is rejected?

If your application is rejected, the IRS will send you a notice explaining the reason, such as missing documents, an incomplete Form W-7, or an invalid tax return. You can then correct the issues and resubmit your application.
