ITIN Requirements for Danish Copywriters Serving U.S. Clients
Danish copywriters who earn income from U.S. clients often require an Individual Taxpayer Identification Number (ITIN). This need arises when U.S. clients issue payments without withholding taxes, typically using forms like W-8BEN-E. Unlike U.S. residents who use a Social Security Number (SSN), individuals without an SSN who must file U.S. taxes need an ITIN. For copywriters in Denmark, this scenario is common when contracting with American businesses directly. Failure to obtain the correct tax identification can lead to payment delays or incorrect tax reporting by your clients, impacting your ability to receive timely compensation. The IRS uses the ITIN to track tax obligations for non-residents earning U.S. income. This number is distinct from an Employer Identification Number (EIN), which is used for businesses, not individuals. Understanding when you need an ITIN is the first step in ensuring compliance and smooth payment flows from your U.S. clients.
This specific need arises because U.S. clients are required to report payments made to foreign individuals or entities. When you provide a W-8BEN-E form, you are declaring your non-U.S. status and potentially claiming benefits under tax treaties. To process these forms correctly and to comply with U.S. tax law, your clients will often require you to have a U.S. taxpayer identification number. For individuals, this is the ITIN. If you are a Danish copywriter working remotely for U.S. businesses, you are likely to encounter this requirement, especially if you are paid via direct deposit or wire transfer without U.S. tax withholding. The ITIN enables the IRS to track your U.S. tax liability, if any. It is essential for accurately reporting income earned from U.S. sources. Without it, clients may be forced to withhold taxes at the highest applicable rate, which is generally not desirable for either party. The Denmark–U.S. tax treaty may offer benefits, but these require proper identification to be claimed. You will need to file U.S. tax returns, such as Form 1040-NR (Nonresident Alien Income Tax Return), to report this income and claim any treaty benefits. The ITIN serves as your identifier for these filings.
When You Must Obtain an ITIN
You are generally required to obtain an ITIN if you are a nonresident alien who must file a U.S. tax return but does not have and cannot obtain an SSN. For freelance copywriters in Denmark, specific situations trigger this requirement. The most common trigger is receiving payments from U.S. clients that are reported on a Form 1099-MISC or 1099-NEC, or equivalent information returns, if you were classified as an independent contractor. Even if your U.S. client does not issue a 1099, they will likely require a completed Form W-8BEN-E from you. This form certifies your foreign status and may allow for reduced or eliminated U.S. tax withholding under the Denmark–U.S. tax treaty. To validate your identity and tax status for these purposes, the IRS issues an ITIN. Another common trigger is the need to claim tax treaty benefits on U.S. source income. For example, if you are receiving royalties or certain types of passive income from U.S. sources, you may need an ITIN to file a return and claim treaty reductions in withholding.
Furthermore, if you are required to file informational returns, such as Form 5472 for certain transactions with a foreign-owned U.S. business, you may need an ITIN. While this is less common for individual freelance copywriters, it could apply if you operate through a U.S. LLC. The IRS also requires an ITIN for individuals who must file a U.S. tax return for other reasons, such as selling U.S. real property or having significant U.S. investment income. For Danish copywriters, the primary trigger is typically earning service income from U.S. clients who report these payments. It is crucial to understand that an ITIN is for tax purposes only and does not grant work authorization in the U.S. It simply allows the IRS to track your tax obligations as a nonresident alien. If you are unsure whether your U.S. income requires an ITIN, consult with a tax professional specializing in U.S. international taxation.
Essential Documents for Your ITIN Application
To apply for an ITIN, you must complete and submit IRS Form W-7. This form requires you to provide personal information, including your foreign tax identification number (if applicable) and your U.S. tax return (or documentation supporting an exception). In addition to Form W-7, you must submit original identification documents or certified copies from the issuing agency to prove your identity and foreign status. The IRS prefers a valid U.S. passport as the primary identification document.
If you do not have a U.S. passport, other acceptable documents include: a national identity card showing your photograph, name, address, date of birth, and expiration date; a foreign driver's license; a civil birth certificate; a foreign voter's registration card; a visa; or a U.S. state-issued identification card. For copywriters in Denmark, a Danish passport is the most straightforward and preferred identification document. Ensure that the name on your Form W-7 exactly matches the name on your identification document. Any discrepancies can lead to delays or rejection of your application. You will also need to include a U.S. federal income tax return for the year you are claiming the ITIN, unless you qualify for an exception, such as applying as part of a tax treaty benefit claim. It is vital that all submitted documents are current and valid. Expired documents will not be accepted. If you are submitting certified copies, they must be obtained directly from the agency that issued the document (e.g., the passport-issuing authority).
The ITIN Application Process and Timeline
The standard process for obtaining an ITIN involves completing Form W-7 and gathering supporting documentation, including your identification and a U.S. tax return. You have three main options for submitting your application. You can mail the completed Form W-7 and all original supporting documents directly to the IRS in Austin, Texas. However, this method involves mailing your original identification documents, which carries a risk of loss or delay. The IRS will retain your original documents until the ITIN is issued, which can take many weeks or even months. Once processed, the IRS will mail your original documents back to you, along with your ITIN assignment letter, typically CP-565.
Alternatively, you can apply through a IRS-authorized Certified Acceptance Agent (CAA). This is often the most efficient and secure method. A CAA can verify your original identification documents on your behalf and forward your application to the IRS without you having to mail your originals. This significantly reduces the risk of losing your important documents. The typical timeline when applying through a CAA like itin.net is much faster, often within 5–10 business days for the application to be processed by the IRS. The IRS then assigns the ITIN. The entire process, from submission to receiving your ITIN, can still take several weeks, depending on IRS processing volumes. A third option is to visit a Taxpayer Assistance Center (TAC) that offers ITIN application services. However, TACs require appointments, and their availability can be limited. Applying via a CAA is generally recommended for Danish copywriters due to the speed and security it offers, minimizing the risk associated with mailing original documents.
Common Application Errors for Danish Copywriters
Freelance copywriters in Denmark seeking an ITIN can encounter specific pitfalls during the application process. One of the most frequent errors is an incomplete Form W-7. This includes missing signature, incorrect or missing personal details, or failing to select the correct reason for applying for an ITIN. Ensure every field is accurately filled out, especially your name, address, and foreign tax identification number if you have one. Another common mistake is not including a valid U.S. tax return with the application, or failing to qualify for one of the exceptions. For example, if you are applying based on claiming tax treaty benefits, you must correctly identify the relevant treaty article on Form W-7 and attach the required documentation. Misstating or incorrectly applying the Denmark–U.S. tax treaty provisions is a significant error that can lead to rejection.
Mismatched names between Form W-7 and your identification documents are also a frequent cause of rejection. If your legal name has changed, ensure you provide documentation supporting the change, such as a marriage certificate or court order. Mailing original identification documents directly to the IRS without proper certification can also be problematic, leading to potential loss or damage. While the IRS allows this, using a Certified Acceptance Agent (CAA) mitigates this risk. Ensure you are using the correct version of Form W-7. The IRS updates forms periodically, and using an outdated version will result in your application being rejected. Finally, failing to sign and date Form W-7 is a simple but common oversight that invalidates the entire application. Double-checking all information and ensuring all required documents are present and accurate before submission is critical for a smooth application process.
Benefits of Using a Certified Acceptance Agent (CAA)
Applying for an ITIN through a Certified Acceptance Agent (CAA) offers significant advantages for Danish copywriters, primarily concerning the handling of original identification documents. When you apply directly to the IRS, you must mail your original passport or other primary identification documents. These documents are sent back to you after processing, but the period without them can be lengthy and stressful, potentially causing issues if you need your passport for travel. A CAA, such as itin.net, is an IRS-authorized third party that can authenticate your identity and foreign status by reviewing your original documents. They then forward a certified copy of your documentation along with your application to the IRS. This means you retain your original documents throughout the entire process.
This service significantly reduces the risk of losing your vital identification documents. Furthermore, CAAs are trained to assist applicants in correctly completing Form W-7 and understanding the documentation requirements. This expertise can help prevent common errors that often lead to application delays or rejections. The typical processing time for applications submitted via a CAA is also often faster, as the IRS may prioritize these applications or have established expedited channels. For copywriters in Denmark, this means a quicker path to obtaining the necessary ITIN, allowing them to receive payments from U.S. clients without undue delay or complications. The fee for using a CAA is separate from the IRS, but the convenience, security, and speed it provides often outweigh the cost. It is an investment in a smoother and more reliable tax compliance process for your U.S. income.
Next Steps After Obtaining Your ITIN
Once you receive your ITIN from the IRS, typically via a CP-565 notice, your immediate tax compliance needs for U.S. income are addressed. You should promptly provide your ITIN to any U.S. clients or payers who requested it, updating your W-8BEN-E form or any other required documentation. This ensures they can correctly report payments made to you and apply any applicable tax treaty benefits. It is also crucial to keep your ITIN confirmation letter (CP-565) in a safe place, as you will need it for future tax filings and correspondence with the IRS.
Your next step is to file your U.S. tax return for the relevant tax year. As a nonresident alien earning U.S. income, you will likely need to file Form 1040-NR. This return is where you report your U.S. source income, claim any allowable deductions and credits, and report any U.S. taxes withheld. If you are claiming benefits under the Denmark–U.S. tax treaty, you will need to attach relevant forms and documentation to your tax return to substantiate your claim. Consider consulting with a tax professional experienced in international taxation to ensure your tax return is filed accurately and efficiently. For ongoing U.S. business activities or if you plan to expand your U.S. operations, you may also need to consider forming a U.S. LLC or obtaining an EIN.

Practical tips
- Ensure the legal name on your Form W-7 exactly matches your passport or other primary identification document; any discrepancies can cause application delays or rejection.
- When applying through a Certified Acceptance Agent (CAA), you will retain your original identification documents, avoiding the risk of loss or extended absence of your passport.
- If your U.S. client requires you to fill out a W-8BEN-E form, ensure you have your ITIN (or know how to obtain one) to properly certify your tax residency and claim treaty benefits.
- Keep a copy of your submitted Form W-7 and all supporting documents for your records, as well as the official ITIN assignment letter (CP-565) once received.
- If you are also considering setting up a U.S. business entity, remember that an ITIN is for individual tax purposes, while an EIN is for business tax identification. You may need both.
Frequently asked questions
Do I need an ITIN if my U.S. client pays me in Euros and not USD?
The currency of payment is generally irrelevant; what matters is that the income is sourced from the United States. If you are a Danish copywriter providing services to a U.S. client, the income is considered U.S. source, and you will likely need an ITIN if you are not a U.S. resident with an SSN.
Can I use my Danish CPR number as identification for the ITIN application?
The IRS requires specific identification documents to prove your identity and foreign status. While a Danish national ID card might be acceptable in some cases, the preferred documents are a valid passport, a foreign driver's license, or a civil birth certificate. Your CPR number itself is not a substitute for these primary identification documents.
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 processing time is typically much faster, often around 5–10 business days for the initial IRS review. However, the entire process, including mailing times and IRS backlogs, can still take several weeks from initial submission to receiving your ITIN assignment letter.
What is the difference between an ITIN and an EIN for a Danish copywriter?
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 for businesses, including U.S. LLCs, to identify them for tax purposes. As a freelance copywriter, you will need an ITIN. If you later decide to form a U.S. LLC, you would then need an EIN.
Will applying for an ITIN affect my tax status in Denmark?
An ITIN is a U.S. tax processing number and does not, by itself, create U.S. tax residency or change your tax residency status in Denmark. However, you are still required to report your worldwide income in Denmark according to Danish tax law. You may be able to claim foreign tax credits in Denmark for any U.S. taxes paid on income that is also taxable in Denmark, subject to the terms of the Denmark–U.S. tax treaty.
Can I use my ITIN to open a U.S. bank account?
Yes, an ITIN can often be used to open a U.S. bank account, especially with digital banks catering to international clients. Many U.S. banks require a U.S. taxpayer identification number, and an ITIN fulfills this requirement when you do not have an SSN. This is particularly useful for freelance copywriters who need to receive payments from U.S. clients easily.
