Why SaaS Founders in Denmark Need an ITIN
SaaS founders in Denmark often encounter U.S. tax obligations due to earning U.S. source income or engaging with U.S. platforms. Unlike U.S. citizens or residents, you likely cannot obtain a Social Security Number (SSN). The IRS requires a nine-digit Individual Taxpayer Identification Number (ITIN) to process your U.S. tax returns when an SSN is unavailable. This is essential for compliance, especially when dealing with U.S. payment processors or investors.
Your business structure, whether a Delaware C-Corp or a Wyoming LLC, might necessitate filings like Form 5472 if it's a disregarded entity owned by a Danish resident. Even if your company is structured as a U.S. LLC, you'll need to ensure compliance with U.S. tax reporting. Receiving payments from U.S. customers or operating through U.S.-based services can trigger these requirements, making the ITIN a critical piece of your U.S. operational puzzle.
The Denmark-U.S. tax treaty is in force, which may affect your U.S. tax liability, particularly regarding withholding taxes on certain types of income. Understanding how this treaty applies to your specific SaaS revenue streams is vital. However, claiming treaty benefits on your U.S. tax return typically requires you to have a U.S. taxpayer identification number, which for individuals, is the ITIN.
This means that even if your U.S. tax liability is reduced to zero due to the treaty, you still need to file the appropriate U.S. tax forms to claim those benefits. Without an ITIN, you cannot file these forms accurately. This creates a compliance hurdle that many SaaS founders overlook until they need to set up essential services like a U.S. bank account or process payments through platforms like Stripe, which may require U.S. tax identification.
When an ITIN is Required for Danish SaaS Founders
An ITIN is required for Danish SaaS founders primarily when you must file a U.S. tax return but are ineligible for an SSN. This most commonly arises if you are receiving U.S. source income that is not subject to adequate withholding at source, or if you are claiming tax treaty benefits on U.S. income. The IRS uses the ITIN to track your tax filings and payments.
For SaaS founders, this can occur in several scenarios. If you are operating as a sole proprietor or a partnership with U.S. customers, the income generated is considered U.S. source income. Even if you are operating through a Danish entity, if you personally receive income directly from U.S. sources that requires U.S. tax reporting, you may need an ITIN.
Furthermore, if your SaaS business is structured as a U.S. entity, such as a U.S. LLC, and you are a foreign owner, you might be subject to reporting requirements like Form 5472. This form is used to report transactions between a U.S. business and a foreign owner or related party. While Form 5472 itself does not require an ITIN for the business, if the reporting triggers a requirement for you, the individual owner, to file a U.S. tax return (e.g., Form 1040-NR), then an ITIN becomes necessary.
Obtaining an EIN (Employer Identification Number) for your U.S. entity, like a Delaware C-Corp, is a separate process from obtaining an ITIN for yourself as an individual. However, these often go hand-in-hand for U.S. business operations. The need for an ITIN is fundamentally tied to your personal U.S. tax filing obligations.
Required Documents for 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 and must be filled out accurately. It is the primary document for your ITIN application.
Crucially, you must also provide original or certified copies of identification documents to verify your identity and foreign status. The IRS prefers a valid passport as the primary identification document. If you do not have a passport, other identification documents may be accepted, but a passport significantly simplifies the process and reduces the risk of rejection.
Supporting documents may include a foreign driver's license, national identity card, or civil birth certificate. However, if you are using documents other than a passport, you will likely need to submit additional documentation to corroborate your identity. The IRS will not return original documents submitted directly to them, so certified copies are often recommended if you cannot afford to mail your original passport.
For SaaS founders in Denmark, your Danish passport will serve as your primary identification. You may also need to include documentation related to your U.S. tax filing obligation, such as a U.S. visa (if applicable) or a copy of the U.S. tax return you are filing concurrently with the Form W-7. If you are claiming treaty benefits, supporting tax documents will be essential to substantiate your claim.
The ITIN Application Process for Danish Founders
The ITIN application process involves submitting Form W-7 along with original or certified copies of your identification documents and a U.S. tax return. You have a few options for submitting your application. You can mail all documents directly to the IRS Service Center in Austin, Texas. However, this method involves mailing original identification documents and can lead to significantly longer processing times.
Alternatively, you can apply through a Certified Acceptance Agent (CAA). This is the recommended path for most applicants, including SaaS founders in Denmark. A CAA, like itin.net, is authorized by the IRS to verify your original identification documents and forward your application to the IRS without you needing to mail your originals. This significantly reduces the risk of losing your passport or other vital documents.
When applying through a CAA, the process is streamlined. You will complete Form W-7 and gather your supporting documents. The CAA will then review your application for completeness, verify your identity documents, and submit the package to the IRS on your behalf. This typically results in a much faster turnaround time for your ITIN.
The IRS generally processes ITIN applications within 5–10 business days when submitted through a CAA. If you mail your application directly to the IRS, processing times can extend to 11 weeks or more, especially during peak tax season. Once the IRS approves your application, they will issue you an ITIN via mail, usually accompanied by a CP-565 notice. You will then use this ITIN for all future U.S. tax filings.
Common Mistakes for Danish SaaS Founders
Danish SaaS founders often make specific errors when applying for an ITIN due to the nuances of international business and U.S. tax law. One common pitfall is failing to include a U.S. tax return with the Form W-7. An ITIN is only issued to individuals who have a valid U.S. tax filing requirement. You must file a tax return (e.g., Form 1040-NR) for the year you are claiming benefits or reporting income.
Another frequent error is submitting incomplete or inaccurate Form W-7 applications. Missing information, incorrect name spellings (especially if they differ between your passport and other documents), or incorrect addresses can lead to delays or rejections. Ensure all fields are completed accurately and consistently with your supporting documentation.
Many overlook the importance of properly substantiating treaty claims. If you are relying on the Denmark-U.S. tax treaty to reduce your U.S. tax liability, you must correctly identify the relevant treaty article and ensure your income qualifies. Incorrect treaty claims are a major reason for IRS scrutiny and potential disallowance of the claimed benefits.
Failure to provide verifiable identification documents is also a common issue. Using expired documents, photocopies instead of originals or certified copies, or documents not accepted by the IRS can halt your application. For Danish founders, ensure your passport is current and valid.
Lastly, misunderstanding the requirement for a U.S. entity's tax filings can cause confusion. If your U.S. LLC requires Form 5472, ensure this is filed correctly. While this form doesn't directly require an ITIN for the entity, it can be part of a larger compliance picture that ultimately necessitates an individual ITIN for reporting purposes.
Benefits of Using a Certified Acceptance Agent (CAA)
Applying for an ITIN through a Certified Acceptance Agent (CAA), such as itin.net, offers significant advantages for SaaS founders in Denmark. The primary benefit is that a CAA can authenticate your original identification documents, like your Danish passport. This means you do not have to mail your originals to the IRS, eliminating the risk of them being lost or stolen during transit.
CAAs are trained and certified by the IRS to review your documentation and ensure your application meets all requirements before it is submitted. This significantly reduces the likelihood of your application being rejected due to common errors, such as incomplete forms or missing documentation. The accuracy check performed by a CAA saves you time and potential frustration.
Furthermore, using a CAA typically accelerates the ITIN application process. Because the CAA is an intermediary with a direct submission channel to the IRS, they can often process applications faster than if you were to mail them directly. The typical processing time through a CAA is 5–10 business days, compared to potentially 11 weeks or more when mailing directly.
As a CAA, itin.net provides a comprehensive service that includes reviewing your Form W-7, verifying your identification, and submitting your application package to the IRS. This end-to-end support is invaluable for individuals who may not be familiar with U.S. tax forms or procedures. It ensures that your application is handled professionally and efficiently.
By leveraging the expertise of a CAA, Danish SaaS founders can confidently navigate the ITIN application process, secure their required tax ID, and focus on growing their businesses without the added stress of dealing directly with IRS mail processing. This allows for a smoother setup of essential services like a U.S. bank account.
Next Steps After Obtaining Your ITIN
Once you receive your ITIN from the IRS, typically via a CP-565 notice, you can proceed with your U.S. tax filing obligations. This includes filing the U.S. tax return that you submitted with your Form W-7. Ensure you use your new ITIN on all subsequent tax forms.
Your ITIN is also essential for opening a U.S. bank account for your business or personal needs, especially if you plan to transact frequently with U.S. customers or partners. Many U.S. banks require a U.S. taxpayer identification number for account opening. Services like Mercury, Relay, or Brex often require either an SSN or an ITIN for non-resident founders.
If you are establishing a U.S. entity, such as a U.S. LLC, your ITIN may be needed for certain reporting requirements or to facilitate business operations. For instance, if you are the sole owner of a U.S. LLC and a foreign resident, you will likely need to file Form 5472 annually, and your ITIN will be used for that reporting.
Reviewing your U.S. tax strategy annually is recommended, especially if your business or income sources change. The Denmark-U.S. tax treaty provisions can be complex and may require adjustments based on evolving circumstances. Consulting with a tax professional familiar with both Danish and U.S. tax law is advisable.

Frequently asked questions
Can I get an ITIN if I only have a Danish driver's license?
While a Danish driver's license can be used as a supporting identification document, the IRS strongly prefers a valid passport. If you do not submit a passport, you must provide additional identification documents to corroborate your identity, which can prolong the application process. It is highly recommended to use your passport if available.
How long does it take to get an ITIN after applying through itin.net?
When you apply through a Certified Acceptance Agent (CAA) like itin.net, the IRS typically processes ITIN applications within 5–10 business days. This is significantly faster than mailing your application directly to the IRS, which can take 11 weeks or more.
Do I need an ITIN to open a U.S. bank account for my SaaS business?
Yes, many U.S. banks, including neobanks catering to startups like Mercury, Relay, or Brex, require a U.S. taxpayer identification number to open an account for a business. For non-residents who cannot get an SSN, an ITIN is often the required identification.
What if my SaaS business income is entirely from non-U.S. sources?
If your SaaS business generates income exclusively from outside the U.S. and you have no other U.S. tax obligations, you likely do not need an ITIN. However, any U.S. source income, or specific reporting requirements related to U.S. entities (like a U.S. LLC), can trigger the need for an ITIN.
How does the Denmark-U.S. tax treaty affect my ITIN application?
The Denmark-U.S. tax treaty does not directly affect your ITIN application itself. However, the treaty often enables you to claim reduced tax rates or exemptions on certain U.S. source income. To claim these treaty benefits, you must file a U.S. tax return, which requires an ITIN if you do not have an SSN.
Can I use my ITIN for my U.S. LLC's tax filings, like Form 5472?
Your ITIN is for your personal U.S. tax obligations. If you own a U.S. LLC, the LLC may need its own EIN. However, if you are a foreign owner required to file Form 5472 for transactions with your U.S. LLC, your personal ITIN will be used on that reporting.
