If you are a Slovenian citizen earning income from U.S. sources, investing in U.S. property, freelancing for American clients, or filing taxes jointly with a U.S. spouse, you may need an ITIN (Individual Taxpayer Identification Number) issued by the IRS.

The good news: the United States and Slovenia have a tax treaty, which allows Slovenians to benefit from reduced withholding tax rates on dividends, royalties, interest, and certain other U.S. income. To access these treaty benefits, an ITIN is required.

At House of Bookkeepers, an IRS-Certified Acceptance Agent (CAA), we help applicants in Slovenia obtain ITIN letters safely and efficiently — without mailing passports to the U.S.

What Is an ITIN?

An ITIN is a nine-digit tax processing number (format: 9XX-XX-XXXX) issued by the IRS for individuals who:

  • Need to file or report U.S. taxes

  • Are not eligible for a U.S. Social Security Number (SSN)

What ITIN is not:

  • Not a U.S. work permit or visa

  • Not immigration status

  • Not a substitute for SSN

Who Commonly Needs ITINs?

  • Nonresident aliens with U.S.-sourced income

  • Real estate investors covered by FIRPTA when selling U.S. property

  • Spouses and dependents of U.S. taxpayers

  • Slovenian students or researchers receiving U.S. scholarships or stipends

  • Freelancers, Amazon sellers, and digital workers paid by U.S. companies

  • Responsible parties of U.S. LLCs

Who in Slovenia Should Apply for an ITIN?

Here are common cases where Slovenians apply for an ITIN:

  • Freelancers and Digital Workers
    Slovenians working with U.S. clients or platforms like Amazon, Upwork, Fiverr, PayPal, Stripe, AdSense, or eBay may face 30% withholding. With an ITIN, they can file U.S. tax returns and apply treaty benefits to lower taxes.

  • Property Investors
    Selling U.S. real estate triggers FIRPTA withholding (15% of the gross sale price). An ITIN is required to file returns and reclaim any excess withholding.

  • Filing Jointly with a U.S. Spouse
    If you are married to a U.S. taxpayer, you need an ITIN to be included on their return and to claim spousal tax credits.

  • Investors in U.S. Companies
    The U.S.–Slovenia tax treaty reduces taxes on dividends, royalties, and other income. An ITIN is required to access these treaty benefits.

  • Responsible Party of a U.S. LLC
    If you own or manage a U.S. LLC, you may need an ITIN to fulfill IRS reporting. Required documents include:

    • Articles of Organization

    • Operating Agreement

    • IRS EIN Confirmation Letter (CP 575 Notice)

Benefits of Having an ITIN

  • File U.S. taxes legally

  • Claim refunds for overpaid withholding

  • Apply reduced tax rates under the U.S.–Slovenia tax treaty

  • Avoid the standard 30% U.S. withholding tax

  • Stay compliant with FIRPTA rules for real estate sales

  • Improve access to U.S. financial institutions (often with EIN/LLC)

U.S.–Slovenia Tax Treaty Benefits

The treaty allows Slovenians to save significantly on U.S. taxes:

  • Dividends: Reduced to 5–15% depending on ownership level

  • Interest: Often reduced or exempt in certain conditions

  • Royalties: Reduced rates (commonly around 5–10%)

  • Students & Researchers: Certain scholarships or fellowships may be exempt from U.S. tax

👉 To claim treaty benefits, you need:

  • An ITIN

  • The correct IRS form (such as Form W-8BEN or Form 8233) provided to the U.S. payer

Step-by-Step: How to Apply for an ITIN from Slovenia in 2025
