ITIN Renewal for Denmark-Based Consultants
Consultants based in Denmark who previously held an ITIN and need to renew it face specific considerations, primarily related to their non-resident status and engagement with U.S. clients. Unlike U.S. residents, your ITIN renewal is not tied to U.S. residency but to your requirement for a U.S. taxpayer identification number for specific U.S. tax obligations. This often arises when a prior ITIN has expired due to the IRS's standard schedule or non-use. The most common trigger for needing an ITIN renewal is the IRS's rolling expiration policy, which invalidates ITINs not used on a federal tax return for three consecutive years. Additionally, the IRS may issue a new ITIN middle-digit expiration schedule. For consultants receiving U.S. source income, maintaining a valid ITIN is essential for compliance and avoiding backup withholding. While Denmark has a tax treaty with the U.S., this generally pertains to withholding rates on certain income types, not the requirement for a U.S. tax identification number itself if U.S. income is earned. Proactive renewal is recommended, rather than waiting for an IRS notice like CP-48, as not all individuals receive such notifications. The itin.net Renewal Package offers a clear path for this process at $397.
When ITIN Renewal is Required
An ITIN renewal becomes mandatory when your existing ITIN has expired. The IRS employs a middle-digit expiration schedule, meaning certain ITINs become invalid every few years. Specifically, ITINs with middle digits 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98, or 99 expire in the order listed. For example, ITINs with middle digits 70-79 expired in 2022, and those with middle digits 80-99 expired in 2023. Furthermore, an ITIN can be invalidated if it has not been used on a federal tax return for three consecutive tax years. For consultants in Denmark, this usually means if you haven't filed a U.S. tax return using your ITIN in three years, you will need to renew it. This situation commonly arises for independent consultants who bill U.S. clients. While the U.S.–Denmark tax treaty may affect how your income is taxed, it does not negate the need for a U.S. taxpayer identification number if you have U.S. source income that requires reporting or withholding. Failing to renew can lead to issues with U.S. tax authorities and potential backup withholding on payments from U.S. clients.
Required Documents for ITIN Renewal
To renew your ITIN, you must submit Form W-7 with the 'Renew an Existing ITIN' box checked. The IRS requires specific supporting documentation to verify your identity and foreign status. The primary document needed is a valid passport. If you do not have a passport, you can use a combination of other identification documents as outlined by the IRS, such as a national identity card with photograph, a driver's license, or a birth certificate (for dependents). However, a passport is the preferred and most straightforward document for non-residents. If available, you should also include your old ITIN notice from the IRS. This notice, often a CP-565, helps the IRS quickly locate your existing record. The most critical document, however, is a current U.S. federal tax return. This demonstrates your need for an ITIN for tax purposes in the current year. For consultants, this would typically be a Form 1040-NR (U.S. Nonresident Alien Income Tax Return). Ensure all documents are originals or certified copies from the issuing agency. Submitting incomplete or incorrect documentation is a common reason for ITIN renewal delays or rejections.
The ITIN Renewal Application Process
The process for ITIN renewal can be completed directly with the IRS or through an authorized Certified Acceptance Agent (CAA). A CAA, like itin.net, can review your application and supporting documents, verify your identity, and forward everything to the IRS on your behalf. This often streamlines the process and can reduce the time it takes to receive your renewed ITIN. First, ensure you have all required documentation: a completed Form W-7 marked for renewal, your original or certified copy of a valid passport, and a current U.S. federal tax return. If applying through a CAA, you will submit these documents to them. The CAA will then review your application for accuracy and completeness. They verify your original identification documents, meaning you do not have to mail your passport to the IRS. Once reviewed and accepted by the CAA, the application package is forwarded to the IRS. The IRS then processes the application. For applications submitted through a CAA, the typical timeline for receiving your renewed ITIN is 5–10 business days. Applications sent directly to the IRS without CAA assistance may take significantly longer, sometimes several weeks or even months, depending on IRS workload. After processing, the IRS will mail your new ITIN assignment letter (CP-565) directly to you.
Common Mistakes for Denmark Consultants
Consultants based in Denmark renewing their ITIN should be aware of specific pitfalls. A frequent error is submitting a Form W-7 that is not properly filled out for renewal, such as failing to check the 'Renew an Existing ITIN' box. This can cause the application to be processed as a new application, leading to delays or rejection. Another common issue is the submission of incomplete or uncertified identification documents. Remember, if you are not using a Certified Acceptance Agent (CAA), you must mail original identification documents or certified copies from the issuing agency to the IRS, which carries risk. Using a CAA avoids this. Mismatched names between your Form W-7, your passport, and your tax return can also lead to rejection. Ensure consistency in name spelling and order. For consultants, accurately preparing the required U.S. federal tax return (e.g., Form 1040-NR) is critical. Errors on the tax return itself can delay the ITIN renewal process. Finally, attempting to renew only after receiving an IRS notice, like a CP-48, is a mistake. Proactive renewal before your ITIN expires is the most effective strategy. Ensure your entity structure is sound; if you're billing U.S. clients, consider forming a U.S. LLC for liability protection and tax efficiency, which may also impact your tax filing requirements.
Benefits of Using a Certified Acceptance Agent (CAA)
Using a Certified Acceptance Agent (CAA), such as those at itin.net, offers distinct advantages for consultants in Denmark seeking ITIN renewal. The primary benefit is that a CAA can authenticate your original identification documents, like your passport, and verify your application in person. This means you do not have to mail your original passport or other sensitive documents to the IRS, significantly reducing the risk of loss or theft during transit. The CAA acts as an intermediary, ensuring your Form W-7 and supporting documents meet IRS requirements before submission. This reduces the likelihood of application errors and rejections, which can cause significant delays. Furthermore, CAAs are trained by the IRS to handle ITIN applications and renewals accurately. The typical processing timeline for applications submitted via a CAA is substantially faster, often 5–10 business days, compared to applications sent directly to the IRS, which can take many weeks. This expedited processing is invaluable for consultants who need their renewed ITIN promptly to continue receiving payments from U.S. clients without interruption or backup withholding. The itin.net Renewal Package leverages this efficiency.
Next Steps After ITIN Renewal
Once your ITIN renewal is processed by the IRS, you will receive a notification letter, CP-565, assigning your renewed ITIN. This letter is crucial and should be kept in a safe place along with your other important tax documents. For consultants in Denmark, the renewed ITIN is essential for filing your U.S. federal tax returns accurately and complying with any withholding requirements from U.S. clients. If you have formed a U.S. LLC or another entity, the renewed ITIN may be necessary for its tax filings, such as Form 5472 if it's a single-member LLC owned by a non-resident alien. It's also important to ensure you have a U.S. bank account set up for your business operations, which can simplify transactions with U.S. clients and manage your U.S. source income effectively. If you have any doubts about the renewal process, the required documentation, or subsequent tax obligations, it is advisable to consult with a qualified tax professional or attorney specializing in international taxation.

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 federal tax return filed with Form W-7 is accurate and complete. Errors on the tax return can delay the ITIN renewal.
- If you have a prior ITIN notice (CP-565), include it with your renewal application. This helps the IRS locate your record faster.
- Always use the 'Renew an Existing ITIN' box on Form W-7. Checking the 'New Applicant' box will cause your application to be rejected or processed as a new application.
- Consider establishing a U.S. LLC and obtaining an Employer Identification Number (EIN) via Form SS-4 before renewing your ITIN, as this structure can offer liability protection and tax benefits for consultants billing U.S. clients.
Frequently asked questions
How long does it take to renew an ITIN through a Certified Acceptance Agent (CAA) in Denmark?
When you use a Certified Acceptance Agent (CAA) like itin.net, the typical processing time for an ITIN renewal is 5–10 business days after the CAA submits your application to the IRS. This is significantly faster than applying directly to the IRS.
Can I renew my ITIN if I haven't used it for my U.S. taxes in a few years?
Yes, if your ITIN has expired due to non-use for three consecutive tax years or due to the IRS's middle-digit expiration schedule, you can renew it by submitting Form W-7 with a current U.S. federal tax return and required identification documents.
What identification documents are required for ITIN renewal for someone in Denmark?
The primary identification document required is a valid passport. If you do not have a passport, other documents like a national identity card with a photograph or a driver's license may be accepted, but a passport is preferred. You will also need a current U.S. federal tax return.
Do I need to send my original passport to the IRS for ITIN renewal?
No, you do not need to mail your original passport to the IRS if you apply through a Certified Acceptance Agent (CAA). The CAA will verify your original identification documents in person and send certified copies or verification to the IRS, meaning you retain your original passport.
What is the difference between getting an EIN and renewing an ITIN for a consultant in Denmark?
An ITIN is a taxpayer identification number for individuals who need to file U.S. taxes but do not have and are not eligible for a Social Security Number. An EIN (Employer Identification Number) is for businesses. Consultants often need both: an ITIN for personal tax filings and potentially an EIN for a U.S. business entity like a U.S. LLC, which is recommended for liability and tax efficiency.
Should I form a U.S. LLC before renewing my ITIN?
For independent consultants billing U.S. clients, forming a U.S. LLC is strongly recommended for liability protection and tax efficiency. While not strictly required for ITIN renewal, it's often a logical next step. You may need an EIN for the LLC, and your ITIN renewal ensures you can meet U.S. tax obligations related to your consulting income.
