Why Danish Contractors Need an ITIN
If you are a contractor based in Denmark and receive income from U.S. sources, you likely need an Individual Taxpayer Identification Number (ITIN). This requirement typically arises when a U.S. client or platform needs to issue you tax forms like Form 1099, or when you are obligated to file a U.S. tax return but are ineligible for a Social Security Number (SSN). Unlike U.S. citizens or residents who have an SSN, foreign contractors without an SSN must obtain an ITIN to comply with U.S. tax regulations. The Denmark–U.S. tax treaty may offer benefits, but fulfilling U.S. tax filing obligations is a prerequisite for claiming them, and an ITIN is central to this process. Without it, you may face backup withholding at the highest rate on your U.S. income, significantly impacting your earnings.
When You Need an ITIN
An ITIN is required for foreign contractors in Denmark when U.S. income is earned and no SSN is available. This includes income from services performed for U.S. companies, royalties, or other U.S.-sourced income that necessitates filing a U.S. tax return. For example, if you are invoicing a U.S. client and they require a completed W-8BEN form (Certificate of U.S. Tax Liability for Foreign Individuals), they may also need your ITIN to properly report payments to the IRS. This is particularly common for independent contractors working remotely for U.S. businesses. The IRS uses the ITIN to track tax filings for individuals who cannot obtain an SSN, ensuring compliance with U.S. tax law. Even if you are not actively earning U.S. income but are required to file a U.S. tax return for other reasons, such as certain investment income, an ITIN becomes necessary.
Required Documents for Your ITIN Application
To apply for an ITIN, you must submit Form W-7 along with original or certified copies of supporting identification documents to the IRS. The most commonly accepted primary identification document is a valid passport. If you do not have a passport, other documents like a national identity card, driver's license, or birth certificate may be accepted, but a passport is strongly preferred by the IRS for its comprehensive identity and nationality information. In addition to identification, you must typically include a U.S. tax return with your Form W-7 application, unless you qualify for an exception. For foreign contractors in Denmark, this usually means filing a Form 1040-NR (U.S. Nonresident Alien Income Tax Return) for the tax year in which you are claiming benefits under the Denmark–U.S. tax treaty or reporting U.S. income. Ensure all documents are current and accurately reflect your legal name.
ITIN Application Process: Step-by-Step
Applying for an ITIN involves several key steps. First, you must complete Form W-7, Application for IRS Individual Taxpayer Identification Number. Accuracy is paramount; any errors can lead to delays or rejections. Second, gather your supporting documentation, which includes a valid identification document (preferably a passport) and a completed U.S. tax return. Third, submit the Form W-7 and supporting documents to the IRS. You have three primary submission options: mail your original documents directly to the IRS in Austin, Texas; use the IRS's walk-in Taxpayer Assistance Center (TAC) services (appointments are often required); or apply through a Certified Acceptance Agent (CAA). The CAA option, offered by services like itin.net, is generally the fastest and most secure, as the CAA can verify your original documents and submit your application on your behalf, often resulting in a processing time of 5–10 business days. If you mail your originals directly to the IRS, expect significantly longer processing times, potentially several weeks or months, and the risk of losing your original documents.
Common Pitfalls for Danish Contractors
Foreign contractors in Denmark face specific challenges when applying for an ITIN. A frequent mistake is failing to include a complete and accurate U.S. tax return with Form W-7. This often happens when contractors misunderstand their U.S. tax obligations or incorrectly fill out forms like the 1040-NR. Another common issue is submitting incomplete or expired identification documents. The IRS requires clear, government-issued identification, and photocopies are generally not accepted unless certified by a CAA. Mismatched names between your identification, your tax return, and Form W-7 are also a major cause for rejection. For instance, if your passport shows your legal name but your tax return uses a professional name, the IRS may flag it. Finally, incorrectly claiming benefits under the Denmark–U.S. tax treaty without proper substantiation or understanding can lead to application denial. Ensure you understand the treaty's provisions relevant to your income type.
Benefits of Using a Certified Acceptance Agent (CAA)
Applying for an ITIN through a Certified Acceptance Agent (CAA) streamlines the process and adds a layer of security. As a CAA, itin.net can verify your original identification documents, such as your passport, and send certified copies to the IRS. This means you do not have to mail your original, irreplaceable documents, significantly reducing the risk of loss or theft during transit. The CAA also reviews your Form W-7 and accompanying tax return for accuracy before submission, helping to prevent common errors that lead to IRS rejections. This verification process often expedites the IRS's review. While the IRS typically takes 7–10 weeks to process ITIN applications submitted directly, using a CAA can shorten this timeframe to 5–10 business days for the initial application review and submission. This efficiency is invaluable for contractors needing their ITIN quickly to meet client or tax deadlines.
Next Steps After ITIN Application
Once the IRS approves your ITIN application, you will receive an ITIN assignment letter, typically IRS Form CP-565. This letter contains your unique 9-digit ITIN. You will need this number for any future U.S. tax filings and for your U.S. client to report payments accurately. If you plan to conduct more significant business in the U.S., you might also need an Employer Identification Number (EIN) for your business entity, which can be applied for separately. For those establishing a U.S. business presence, consider forming a U.S. LLC, which may facilitate opening a U.S. bank account. If you need assistance with your ITIN application, understanding U.S. tax obligations, or navigating the complexities of U.S. business for foreign contractors, itin.net offers comprehensive support.

Practical tips
- Use the same legal name across Form W-7, your passport, and any prior IRS correspondence; mismatched name fields are the most common rejection reason.
- Ensure your U.S. tax return (e.g., Form 1040-NR) is correctly filed and accurately reflects your U.S. income and any treaty benefits claimed before submitting it with your Form W-7.
- When applying through a Certified Acceptance Agent (CAA), you can submit certified copies of your identification documents, avoiding the need to mail originals to the IRS.
- If you are invoicing U.S. companies, understand whether you need to fill out Form W-8BEN (for individuals) or W-8BEN-E (for entities) in addition to obtaining your ITIN.
- Keep a copy of your submitted Form W-7 and all supporting documents for your records. Note the date of submission and follow up if you do not receive your ITIN assignment letter within the expected timeframe.
Frequently asked questions
Do I need an ITIN if I am a contractor in Denmark but only invoice Danish companies?
No, an ITIN is specifically for U.S. tax purposes. If your income is solely from Danish sources and you have no U.S. tax obligations, you do not need an ITIN.
What is the Denmark–U.S. tax treaty and how does it affect my ITIN application?
The Denmark–U.S. tax treaty reduces or eliminates U.S. taxes on certain types of income. To claim these benefits, you typically need to file a U.S. tax return and have an ITIN (or SSN if applicable). Your ITIN application often includes the tax return claiming treaty benefits.
Can I use my Danish driver's license as identification for my ITIN application?
While a Danish driver's license might be accepted as a secondary form of identification, the IRS strongly prefers a passport as the primary document for ITIN applications due to its verification of nationality and identity. If you use a driver's license, you will likely need to provide additional identifying documents.
How long does it take to get an ITIN if I apply from Denmark?
If you apply through a Certified Acceptance Agent (CAA) like itin.net, the process can take 5–10 business days for submission and initial IRS processing. Mailing your application directly to the IRS can take several weeks to months.
What if my name on my passport is different from my professional name?
You must use your legal name exactly as it appears on your government-issued identification document (like your passport) on Form W-7 and your U.S. tax return. If there are discrepancies, you may need to provide additional documentation or legally change your name before applying.
Can I open a U.S. bank account with an ITIN?
Yes, many U.S. banks and financial institutions accept an ITIN as a valid form of identification for opening a business or personal U.S. bank account, especially if you are also setting up a U.S. entity like a U.S. LLC. This can be crucial for receiving payments from U.S. clients.
