Why Lithuanian Toptal Contractors Need an ITIN
As a Toptal contractor based in Lithuania, you likely engage with U.S. clients. U.S. clients often require you to complete Form W-8BEN to certify your foreign status and claim treaty benefits, which can reduce U.S. tax withholding on certain types of income. However, to fully benefit from the Lithuania–U.S. tax treaty, particularly for income not covered by Form W-8BEN or if you have other U.S. tax filing obligations, you will need an Individual Taxpayer Identification Number (ITIN).
The ITIN is a 9-digit IRS tax ID for individuals who must file U.S. taxes but cannot obtain a Social Security Number. For Toptal contractors in Lithuania, this often arises when you have U.S. sourced income that exceeds the thresholds for treaty benefits or if you are required to file a U.S. tax return for other reasons. Without an ITIN, you may face higher withholding rates than applicable under the treaty, or you might be unable to fulfill certain U.S. tax filing requirements.
When an ITIN is Required for Toptal Contractors
The primary trigger for needing an ITIN as a Toptal contractor in Lithuania is the requirement to file a U.S. tax return. This can occur if you have U.S. income that is not subject to adequate withholding, or if you have specific types of U.S. income like effectively connected income from a U.S. trade or business. Even if your income is passive and subject to withholding, obtaining an ITIN allows you to claim treaty benefits more effectively, potentially reducing the withholding rate.
For instance, if your Toptal contract involves services performed while physically present in the U.S., or if your income is structured in a way that necessitates filing a U.S. tax return (such as Form 1040-NR), an ITIN becomes essential. The IRS issues ITINs to individuals who have a U.S. tax filing requirement. Without it, you may be unable to properly report your income, claim deductions or credits, or benefit from tax treaty provisions. It's also a prerequisite for opening certain U.S. bank accounts that may be advantageous for your business operations.
Required Documentation for Your ITIN Application
To apply for an ITIN, you must submit Form W-7, Application for IRS Individual Taxpayer Identification Number. This form requires detailed personal information, including your name, address, foreign tax identification number (if applicable), and reason for applying for an ITIN.
Alongside Form W-7, you must provide original identification documents or certified copies from the issuing agency. The most commonly accepted document is a valid passport. If you do not have a passport, other documents like a national identity card, birth certificate, or foreign driver's license may be accepted, provided they meet specific IRS criteria and include your photograph and/or signature. You will also need to include documentation supporting your reason for needing an ITIN, such as a U.S. tax return or a statement from a third party. For Toptal contractors, this often means including a copy of your U.S. tax return (e.g., Form 1040-NR) or a letter explaining your U.S. income and treaty claim.
The ITIN Application Process for Lithuanian Residents
The ITIN application process typically begins with completing Form W-7. You have several options for submitting your application. One method is to mail the completed form along with your original supporting identification documents and your U.S. tax return directly to the IRS in Austin, Texas. However, this method involves mailing your original passport, which can take several weeks to return, and the IRS processing times can be lengthy and unpredictable.
A more efficient and secure method is to apply through a Certified Acceptance Agent (CAA), like itin.net. A CAA can verify your original identification documents and forward your application to the IRS on your behalf. This eliminates the need to mail your original passport. The typical timeline when applying through a CAA is much faster, often around 5–10 business days for the IRS to assign the ITIN after receiving a complete application. This expedited process significantly reduces the risk of losing your vital documents during transit.
Common Mistakes for Toptal Contractors in Lithuania
Toptal contractors from Lithuania often encounter specific pitfalls when applying for an ITIN. A frequent error is an incomplete Form W-7. Ensure every field is accurately filled out, especially the section detailing the reason for your ITIN application and any claims related to tax treaties. Mismatched names between your Form W-7, passport, and any other supporting documents can also lead to rejection.
Another common issue is failing to include a complete and accurate U.S. tax return with your Form W-7 application, if required. For Toptal contractors, this might involve improperly calculating income or failing to claim the correct treaty article. Forgetting to sign and date the form is another frequent oversight. When using a Certified Acceptance Agent (CAA), ensure you provide all necessary documentation to them promptly to avoid delays in their verification process.
Applying Through a Certified Acceptance Agent (CAA)
Applying for an ITIN through a Certified Acceptance Agent (CAA) offers distinct advantages, especially for international contractors. As a CAA, itin.net can authenticate your original identification documents, such as your passport, without you having to mail them to the IRS. This means your original documents are returned to you directly by the CAA, significantly reducing the risk of loss or delay.
Furthermore, a CAA helps ensure your Form W-7 and supporting documentation are complete and correctly filled out before submission to the IRS. This pre-screening process minimizes the chances of your application being rejected due to common errors. The typical processing timeline is also considerably shorter when using a CAA, as the IRS prioritizes applications submitted by authorized agents. This efficiency is critical for contractors who need their ITIN to meet tax filing deadlines or client requirements.
Next Steps After Receiving Your ITIN
Once you receive your ITIN from the IRS, typically via mail as a CP-565 notice, you can use it for all future U.S. tax filings. This includes filing your annual U.S. tax return (e.g., Form 1040-NR) and any other required IRS forms. Your ITIN is a permanent number and does not expire, though it may be subject to renewal if you do not file a U.S. tax return for three consecutive tax years.
With your ITIN, you can now ensure your U.S. client engagements are compliant with tax regulations and that you are benefiting from the Lithuania–U.S. tax treaty. If you plan to establish a U.S. business entity, such as a U.S. LLC, an ITIN might be a prerequisite for certain filings like Form 5472, and it can also facilitate opening a U.S. bank account.

Practical tips
- Use the same legal name across Form W-7, your passport, and any prior IRS correspondence; mismatched name fields are a common reason for ITIN application rejection.
- Ensure your supporting identification document, like a passport, is valid and not expired at the time of application.
- When claiming tax treaty benefits, accurately reference the specific treaty article on Form W-7 and include a supporting U.S. tax return.
- If you are mailing your application directly to the IRS, send copies of your identification documents certified by the issuing agency, not originals, unless specifically instructed otherwise.
- Keep a copy of your submitted Form W-7 and all supporting documents for your records.
Frequently asked questions
Do I need an ITIN if I'm a Toptal contractor in Lithuania earning USD?
You may need an ITIN if you are required to file a U.S. tax return or if you need to claim specific U.S. tax treaty benefits that reduce withholding on your income. Simply earning USD does not automatically require an ITIN, but U.S. sourced income often triggers U.S. tax obligations.
Can I use my Lithuanian passport to apply for an ITIN?
Yes, a valid Lithuanian passport is one of the preferred identification documents accepted by the IRS for ITIN applications. Ensure it is not expired.
How long does it take to get an ITIN as a contractor in Lithuania?
When applying through a Certified Acceptance Agent (CAA) like itin.net, the IRS typically issues an ITIN within 5–10 business days after they receive your complete application. Mailing directly to the IRS can take significantly longer and is less predictable.
What is the difference between an ITIN and an EIN for Toptal contractors?
An ITIN (Individual Taxpayer Identification Number) is for individuals who need to file U.S. taxes but cannot get an SSN. An EIN (Employer Identification Number) is a tax ID for businesses, not individuals. As a Toptal contractor, you will likely need an ITIN for personal tax filing. If you form a U.S. business entity, you would then need an EIN.
Can I open a U.S. bank account with an ITIN?
Many U.S. banks and financial institutions allow non-residents to open business or personal accounts using an ITIN, especially if you also have proof of a U.S. business entity like a U.S. LLC. Services like itin.net can assist with the ITIN application, which is a step towards opening a U.S. bank account.
What happens if I don't get an ITIN when I should have?
Failure to obtain an ITIN when required can lead to penalties, interest on underpaid taxes, and potentially higher tax withholding rates than applicable under the Lithuania–U.S. tax treaty. It may also hinder your ability to file your U.S. taxes correctly and on time.
