Why Upwork Freelancers in Slovakia Need an ITIN
Upwork freelancers based in Slovakia face a unique tax situation when earning income from U.S. clients. The primary trigger is the need to file U.S. tax returns, often necessitated by the structure of their client agreements or specific U.S. tax regulations. While many non-residents can work with U.S. clients without immediate U.S. tax obligations, Upwork's payment system and client expectations often require specific tax documentation. This is where the Individual Taxpayer Identification Number (ITIN) becomes essential. It's a 9-digit IRS tax ID for individuals who must file U.S. taxes but cannot obtain a Social Security Number (SSN).
The friction point for Upwork freelancers in Slovakia typically arises when they need to provide tax information to their U.S. clients or payment processors. Many clients, especially larger companies, require contractors to fill out IRS Form W-8BEN to certify foreign status and claim treaty benefits, thereby reducing U.S. withholding taxes. However, if a freelancer's activities create a U.S. nexus or if they are required to file a U.S. tax return for other reasons (e.g., specific types of income, exceeding certain thresholds), an ITIN is mandatory.
Without an ITIN, freelancers may face higher withholding tax rates on their U.S. income, potentially impacting their net earnings significantly. Furthermore, failure to provide correct tax documentation can lead to payment holds or even account suspension on platforms like Upwork. This makes obtaining an ITIN not just a compliance issue, but a practical necessity for smooth and profitable freelancing operations with U.S. clients. The process involves specific forms and documentation, and understanding it is key to avoiding delays and errors.
When You Need an ITIN
An ITIN is required for Upwork freelancers in Slovakia primarily when you must file a U.S. tax return. This obligation is typically triggered by earning certain types of income from U.S. sources that exceed specific thresholds, or if your business activities are deemed to create a U.S. tax presence. For example, if you provide services that are considered U.S. sourced, and these earnings are substantial, the IRS may require you to file a U.S. tax return using Form 1040-NR (U.S. Nonresident Alien Income Tax Return).
Another common scenario involves requirements from payment processors or clients. While Form W-8BEN is used to certify foreign status and potentially claim treaty benefits to reduce withholding, there are situations where this form alone is insufficient. If your engagement with a U.S. client, despite being based in Slovakia, is structured in a way that suggests a U.S. trade or business, or if you receive specific types of income not covered by standard W-8BEN exemptions, the IRS might mandate a U.S. tax filing. This would necessitate an ITIN.
Furthermore, if you are establishing a U.S. business entity, such as a U.S. LLC, for your Upwork operations, you might need an ITIN for the entity or for yourself if you are involved in U.S. tax filings related to that entity. While an EIN (Employer Identification Number) is for businesses, individuals associated with U.S. tax obligations often require an ITIN. The key takeaway is that any requirement to file a U.S. tax return, or specific instructions from clients or financial institutions that point towards U.S. tax filing obligations, are direct triggers for obtaining an ITIN.
Required Documents for ITIN Application
Applying for an ITIN requires submitting specific documentation to the IRS, primarily through Form W-7, Application for IRS Individual Taxpayer Identification Number. This form must be completed accurately and in full. Alongside Form W-7, you must provide original or certified copies of documents proving your identity and foreign status.
The IRS prefers a valid passport as the primary identification document. If you possess a passport, it is generally the easiest document to use. It must be valid and unexpired at the time of application. If a passport is not available, other documents may be accepted, but they must be presented in a specific combination to meet IRS requirements. These can include a national identification card (with photo, name, address, DOB, and expiration date), a driver's license, a birth certificate (for dependents), or a foreign voter's registration card.
Crucially, you must also provide documentation that supports your reason for needing an ITIN. For Upwork freelancers, this often means providing a copy of your U.S. tax return that you are filing concurrently with the W-7, or documentation demonstrating your need to file. For example, if you are claiming tax treaty benefits under the Slovakia–U.S. tax treaty, you might need to reference the specific treaty article and provide supporting tax documents. The IRS also requires proof of foreign status, which is typically demonstrated by the same documents used for identification, such as a passport. Ensure all documents are either originals or certified copies from the issuing agency.
The ITIN Application Process
The application process for an ITIN involves several distinct steps. First, you must complete Form W-7 accurately. This form requests personal information, including your name, address, date of birth, and country of citizenship. It also requires you to state the reason for applying for an ITIN, such as needing to file a U.S. tax return.
Once Form W-7 is completed, you need to gather your supporting documentation. This includes your original or certified copies of identification documents (like a passport) and proof of your need for an ITIN, which is often a U.S. tax return. If you are filing Form W-7 with a tax return, you will submit both documents together.
There are three main ways to submit your application: by mail directly to the IRS, by visiting an IRS Taxpayer Assistance Center (TAC), or by using a Certified Acceptance Agent (CAA). Mailing directly to the IRS can result in longer processing times and the risk of losing original documents. Visiting a TAC requires an appointment and you must bring original documents for verification. Using a CAA, like itin.net, is generally the most efficient method. A CAA can verify your original documents, send your application to the IRS, and often expedites the process. The typical timeline when using a CAA is 5–10 business days for the IRS to process the application and issue the ITIN, although IRS processing times can vary.
After the IRS processes your application, they will mail your ITIN directly to you. This confirmation usually comes in the form of IRS notice CP-565. The entire process, from gathering documents to receiving your ITIN, can take several weeks to a few months depending on the submission method and IRS workload.
Common Mistakes for Upwork Freelancers in Slovakia
Upwork freelancers in Slovakia often make specific errors when applying for an ITIN, stemming from a misunderstanding of U.S. tax requirements and the application process. A frequent mistake is failing to provide a complete and accurate U.S. tax return with the Form W-7. Many freelancers believe the ITIN application is separate from their tax obligations, but it's intrinsically linked. The IRS needs to see you are fulfilling your U.S. tax filing duty.
Another common pitfall is incorrect claims regarding tax treaty benefits. While the Slovakia–U.S. tax treaty exists, its application depends on specific income types and residency status. Incorrectly claiming treaty benefits without proper justification on your tax return can lead to ITIN denial or future IRS scrutiny. It's essential to understand which treaty articles apply to your freelance income and ensure your tax return reflects this accurately.
Mismatched information across documents is also a significant issue. Ensure the name on your Form W-7, your passport, and any previous IRS correspondence (if applicable) is identical. Variations in spelling, order of names, or inclusion/omission of middle names can cause processing delays or rejections. Furthermore, some freelancers mistakenly try to mail original identification documents directly to the IRS without using a Certified Acceptance Agent (CAA). The IRS strongly advises against this, as you risk losing vital personal documents. Using a CAA ensures your documents are verified without being sent to the IRS, mitigating this risk.
Benefits of Using a Certified Acceptance Agent (CAA)
Using a Certified Acceptance Agent (CAA), such as itin.net, offers distinct advantages for Upwork freelancers in Slovakia applying for an ITIN. The primary benefit is that a CAA can verify your original identification documents, like your passport. This means you do not have to mail your original documents to the IRS, significantly reducing the risk of them being lost or stolen during transit. The CAA authenticates these documents on behalf of the IRS.
This verification process by a CAA often streamlines the application. Because the CAA has already confirmed the authenticity of your supporting documents and the accuracy of your Form W-7, the IRS can process your application more efficiently. The typical processing time when using a CAA is substantially shorter than mailing the application directly – often within 5–10 business days for the IRS to issue the ITIN after receiving the application from the CAA.
Furthermore, CAAs are trained by the IRS and have a deeper understanding of the ITIN application requirements and common pitfalls. They can help ensure your application is complete and accurate before it is submitted, minimizing the chances of errors that could lead to delays or rejection. For Upwork freelancers in Slovakia, this expertise is invaluable, especially when navigating the complexities of U.S. tax forms and treaty claims. The itin.net Standard Package, for instance, includes this comprehensive support, guiding you through each step.
Next Steps After Obtaining Your ITIN
Once you receive your ITIN from the IRS, usually via notice CP-565, you can proceed with your U.S. tax filings and business operations. The most immediate step is to ensure your U.S. tax return is filed by the deadline, if you applied for the ITIN in conjunction with filing. If you obtained the ITIN for future needs, you can now provide it to clients or payment processors as required.
For Upwork freelancers, this means updating your tax information on the Upwork platform and with any U.S. clients who require it. Providing your ITIN will help ensure correct tax withholding and compliance. If you are subject to U.S. tax, you will use this ITIN on all future U.S. tax filings, including annual returns like Form 1040-NR.
Consider whether you need to open a U.S. bank account. Many freelancers find it beneficial for receiving payments and managing U.S. income separately. Services like Mercury or Relay can be options, though requirements vary. If your freelance income is substantial and you are considering structuring your business for tax efficiency, you might explore forming a U.S. LLC, which would involve obtaining an EIN for the business.

Practical tips
- Use the exact same legal name across Form W-7, your passport, and any prior IRS correspondence; mismatched names are a primary reason for ITIN rejection.
- Ensure your U.S. tax return, filed with Form W-7, accurately reflects your income and any claimed tax treaty benefits under the Slovakia–U.S. treaty.
- When using a Certified Acceptance Agent (CAA), you provide certified copies or originals of your documents to them, not directly to the IRS, safeguarding your originals.
- If you are applying as a dependent, ensure you have proof of your relationship to the sponsor, such as a birth certificate, in addition to your own identification.
- Keep a copy of your submitted Form W-7 and all supporting documents for your records; the IRS may request additional information.
Frequently asked questions
Can I use my Slovakian tax identification number instead of an ITIN?
No, your Slovakian tax identification number is for tax purposes in Slovakia only. The IRS requires an ITIN specifically for U.S. tax filings and other U.S. federal tax matters when you do not have and cannot get an SSN.
How long does it take to get an ITIN through itin.net?
When you apply through a Certified Acceptance Agent (CAA) like itin.net, the IRS typically processes the application within 5–10 business days after receiving it. However, the total time from submitting your documents to us until you receive your ITIN can range from a few weeks to a couple of months, depending on IRS processing times and mail delivery.
What if my passport is expired?
The IRS prefers a valid, unexpired passport. If your passport is expired, you may need to use it in combination with other identifying documents, or renew your passport before applying. Consult the IRS guidelines or a tax professional if your primary identification document is expired.
Do I need an ITIN if I only earn a small amount from Upwork?
Whether you need an ITIN depends on the specific nature of your income and U.S. tax regulations, not just the amount. If your activities create a U.S. tax nexus or if you are required by the IRS or your client to file a U.S. tax return, you will likely need an ITIN, regardless of the income amount. Consult the IRS or a tax professional for specific guidance.
Can I apply for an ITIN and an EIN at the same time?
Yes, you can apply for an ITIN and an EIN concurrently, but they are separate applications for different purposes. An ITIN is for individuals, while an EIN is for businesses. If you are forming a U.S. LLC, you would typically apply for an EIN for the LLC and an ITIN for yourself if needed for personal tax filings.
What happens if the IRS rejects my ITIN application?
If the IRS rejects your ITIN application, they will typically send you a letter explaining the reason for the rejection. Common reasons include incomplete forms, missing or unverified documentation, or incorrect tax return information. You will need to correct the issues identified and resubmit your application.
