Why Lithuanian Tax Refund Claimants Need an ITIN
If you are a tax refund claimant based in Lithuania and have U.S. tax obligations, you likely need an Individual Taxpayer Identification Number (ITIN). This is because the IRS requires an ITIN for non-residents to claim refunds when tax has been over-withheld on U.S. source income, such as from casino winnings, royalties, or dividends. Unlike U.S. citizens or residents who use a Social Security Number (SSN), individuals without an SSN must obtain an ITIN to file necessary U.S. tax returns, like the Form 1040-NR, to receive these refunds. The Lithuania–U.S. tax treaty may offer reduced withholding rates, but if tax was still over-withheld, an ITIN is the key to getting that money back from the IRS. Without it, your refund claim cannot be processed, leaving your overpaid U.S. taxes unclaimed.
Your primary trigger for needing an ITIN as a Lithuanian tax refund claimant is the receipt of U.S. income that has had tax withheld at source. This often occurs with passive income streams or certain types of gambling winnings. The IRS mandates that any individual filing a U.S. tax return must have either an SSN or an ITIN. Since most individuals receiving such income from Lithuania do not qualify for an SSN, the ITIN becomes the essential identification number for filing purposes. This ensures that the IRS can accurately track your tax liability and issue any refund due to you. The process is specifically designed to accommodate foreign nationals who interact with the U.S. tax system but lack a U.S. taxpayer identification number.
Eligibility and Triggers for ITIN Application
Eligibility for an ITIN is straightforward: you must be a foreign national who needs to file a U.S. tax return but cannot obtain a Social Security Number (SSN). For tax refund claimants in Lithuania, this typically arises when U.S. payers (like casinos, dividend-paying U.S. companies, or royalty administrators) withhold U.S. income tax from payments made to you. The IRS requires these payers to report such payments, and if tax is withheld, you will need to file a U.S. tax return, usually Form 1040-NR, to reconcile your tax liability and claim any refund. The specific platform or circumstance triggering the need for an ITIN is the requirement to file a U.S. tax return with the IRS. This is often linked to income types such as gambling winnings, royalties, dividends, or other passive income received from U.S. sources.
Even if you are a resident of Lithuania and benefit from the tax treaty between Lithuania and the U.S., an ITIN is still necessary if tax was over-withheld. The treaty might reduce the rate of withholding, but if the payer applied a higher rate or if you are claiming a refund of tax that was correctly withheld but ultimately not due under the treaty, you must file a tax return. This filing requirement, driven by the need to claim a refund, is the definitive trigger for obtaining an ITIN. Without this number, the IRS has no way to identify you as a taxpayer for the purpose of processing your refund claim. The ITIN serves as your unique identifier within the U.S. tax system for all tax-related activities.
Required Documentation for ITIN Application
To apply for an ITIN, you will need to submit Form W-7, Application for IRS Individual Taxpayer Identification Number. This form requires detailed personal information, including your name, address, and foreign tax identification number (if applicable). It is crucial that the name you provide on the Form W-7 exactly matches the name on your identification documents. In addition to the completed Form W-7, you must provide original identification documents or certified copies of them. The IRS prefers a valid U.S. passport as primary identification.
If a U.S. passport is not available, other acceptable identification documents include a national identity card, a birth certificate, a foreign driver's license, or a foreign voter's registration card. You will need to provide at least one document proving your identity and one proving your nationality or foreign status. For Lithuanian citizens, a valid passport is the most straightforward option. If you are applying to claim tax treaty benefits, you may also need to provide documentation supporting that claim, such as proof of residency in Lithuania. Remember, the IRS requires you to submit these documents with your Form W-7 and your U.S. tax return.
The ITIN Application Process and Timeline
The process for obtaining an ITIN begins with completing Form W-7 and gathering your supporting identification documents. You must also file a valid U.S. federal income tax return (e.g., Form 1040-NR) with the IRS in the same year you submit your Form W-7, unless you qualify for an exception. The most common exception is when applying through a Certified Acceptance Agent (CAA). If you are applying directly to the IRS by mail, you will send your Form W-7, supporting identification documents, and your tax return to the IRS address listed in the Form W-7 instructions. The IRS will then review your application and, if approved, mail you an ITIN assignment letter (IRS notice CP-565).
When applying directly to the IRS by mail, the processing time can be lengthy, often taking 10 to 14 weeks or more, especially during peak tax seasons. However, using a Certified Acceptance Agent (CAA) significantly speeds up the process. A CAA, like itin.net, can verify your original identification documents on your behalf and forward your application directly to the IRS. This means you do not have to mail your original passport or other sensitive documents, and the IRS typically processes applications submitted through a CAA much faster, often within 5–10 business days for the ITIN assignment itself. The IRS will then process your tax return separately.
Common Mistakes for Lithuanian Tax Refund Claimants
Tax refund claimants from Lithuania often make specific errors when applying for an ITIN. One of the most frequent issues is failing to include a complete and accurate U.S. tax return with the Form W-7 application when applying directly to the IRS. Many assume the ITIN application is separate from the tax return, but they must be submitted together unless you are using a Certified Acceptance Agent (CAA) who can verify your documents. Another common pitfall is mailing original identification documents to the IRS when applying by mail; the IRS strongly advises against this, as these documents are not returned promptly, if at all. Using a CAA prevents this risk.
Misstating personal information is another frequent error. Ensure your name, address, and date of birth on the Form W-7 precisely match your identification documents. Discrepancies can lead to delays or rejections. For instance, if your passport lists your name as 'Jonas Petraitis' but your application uses 'J. Petraitis,' it may cause issues. Additionally, incorrect claims related to tax treaty benefits can cause problems. While the Lithuania–U.S. tax treaty exists, applying its provisions incorrectly on your Form 1040-NR without proper understanding can lead to rejection of your refund claim. Always confirm the specific article and conditions that apply to your income type.
Benefits of Using a Certified Acceptance Agent (CAA)
Applying for an ITIN through a Certified Acceptance Agent (CAA) offers distinct advantages for tax refund claimants from Lithuania. As an authorized agent of the IRS, a CAA can authenticate your original identification documents, such as your passport. This means you can submit certified copies or have your originals reviewed by the CAA, and then the CAA forwards your application to the IRS. Consequently, you avoid the risk and inconvenience of mailing your original, sensitive documents directly to the IRS, which can take months to be returned.
The expedited processing is a major benefit. Applications submitted through a CAA are typically processed by the IRS much faster than those sent directly by mail. While direct mail applications can take over a month, CAA-submitted applications often result in the ITIN being assigned within 5–10 business days. This quicker turnaround is invaluable for tax refund claimants eager to receive their over-withheld funds. Services like itin.net act as a CAA, streamlining the entire ITIN application process for non-residents and ensuring accuracy in documentation, which reduces the likelihood of common errors and rejections. This expert guidance is particularly helpful for those unfamiliar with U.S. tax filing requirements.
Next Steps After Obtaining Your ITIN
Once you receive your ITIN assignment letter (IRS notice CP-565) from the IRS, your primary goal of obtaining the number for your tax refund claim is met. You can then use this ITIN on your Form 1040-NR to file your U.S. tax return if you haven't already done so. The IRS will process your tax return and issue your refund, typically via direct deposit or check, after they have verified your return and the ITIN. If you applied through a CAA, they may have already submitted your tax return on your behalf, or they can assist you with filing it once you have your ITIN.
It is important to keep your ITIN secure, just as you would your Social Security Number. You will need it for any future U.S. tax filings. If you anticipate receiving U.S. income in subsequent years or have other U.S. tax obligations, your ITIN will be essential. For those who frequently deal with U.S. income, consider consulting with a U.S. tax professional to ensure ongoing compliance.

Practical tips
- Use the exact same legal name on your Form W-7, your passport, and any prior IRS correspondence to prevent name-mismatch rejections.
- If you are claiming tax treaty benefits, ensure you understand which article applies to your specific income type and that your Form 1040-NR reflects this accurately.

- Double-check all fields on your Form W-7 for accuracy, paying close attention to your date of birth, foreign address, and tax identification number (if applicable).
- If you have previously filed U.S. taxes, ensure your previous tax return information matches the details provided on your current Form W-7 to avoid discrepancies.
Frequently asked questions
Can I get my U.S. tax refund without an ITIN if I live in Lithuania?
No, you generally cannot receive a U.S. tax refund without an ITIN if you are a non-resident required to file a U.S. tax return. The IRS uses the ITIN to identify you and process your refund claim for over-withheld U.S. taxes.
How long does it take to get an ITIN for a tax refund claim from Lithuania?
When applying directly to the IRS by mail, it can take 10–14 weeks or more. If you use a Certified Acceptance Agent (CAA) like itin.net, the ITIN assignment process is significantly faster, often within 5–10 business days, though your tax return will be processed separately by the IRS.
What is the most common mistake Lithuanian residents make on Form W-7?
A very common mistake is failing to submit a complete and accurate U.S. tax return along with the Form W-7 when applying directly to the IRS. Another frequent error is mailing original identification documents instead of using a Certified Acceptance Agent (CAA) to verify them.
Do I need to send my passport to the IRS to get an ITIN?
You do not need to send your original passport to the IRS if you apply through a Certified Acceptance Agent (CAA). The CAA can verify your passport and forward the application without you having to mail the original document.
Can the Lithuania–U.S. tax treaty help me avoid needing an ITIN for a refund?
The tax treaty may reduce the amount of tax withheld from your U.S. income, but if tax was still over-withheld, you will still need an ITIN to file Form 1040-NR and claim the refund. The ITIN is required for the filing process itself.
What happens if my ITIN application is rejected?
If your ITIN application is rejected, the IRS will notify you of the reason, often due to missing documentation, incorrect information, or an incomplete tax return. You will need to correct the errors and resubmit your application. Using a Certified Acceptance Agent (CAA) can help minimize the chances of rejection.
