Why Amazon KDP Authors in Denmark Need ITIN Renewal
Amazon KDP authors based in Denmark face a specific challenge when it comes to their U.S. tax identification: ITIN renewal. Unlike U.S. residents, you publish to a U.S.-based platform and receive royalty payments subject to U.S. tax law. If your Individual Taxpayer Identification Number (ITIN) has expired, you risk a 30% withholding tax on all your KDP earnings. This is because the IRS requires a valid ITIN to properly claim treaty benefits under the Denmark–U.S. tax treaty, which reduces or eliminates U.S. withholding on royalties. Without a current ITIN, the IRS defaults to the highest statutory withholding rate. Denmark authors must proactively manage their ITIN status to ensure uninterrupted income flow and compliance with U.S. tax obligations. The need for renewal isn't just about avoiding penalties; it's about maintaining the tax efficiency of your publishing business.
When Your ITIN Requires Renewal
Your ITIN requires renewal if it has expired due to non-use for three consecutive tax years or because the IRS has updated its middle-digit expiration schedule. For Amazon KDP authors, the trigger is often the need to submit an updated W-8BEN form to Amazon to claim treaty benefits. If your ITIN is no longer valid, Amazon will begin withholding 30% of your royalties. The IRS issues ITINs and manages their validity. While they may send a notice like CP-48 if your ITIN is subject to expiration, relying solely on this notice is risky. Many authors do not receive such notices, or they may be missed among other correspondence. Therefore, it's essential to check your ITIN's status proactively, especially if you haven't used it on a U.S. federal tax return in three years or if it falls within an IRS-designated expiration year based on its middle digits (the first two digits after the 9X-XX). For KDP authors, this is critical to avoid unexpected tax deductions on your earnings.
Required Documents for ITIN Renewal
To renew your ITIN, you will need to complete IRS Form W-7, ensuring you check the box indicating 'Renew an Existing ITIN.' This form requires specific documentation to verify your identity and foreign status. The primary document is typically your valid passport. If you do not have a passport, other identification documents may be accepted, but a passport is the most straightforward option. You will also need your old ITIN notice, if you have it. This notice, often a CP-565 or CP-575, confirms your previously assigned number. Lastly, you must include a current federal tax return that you are filing or intend to file with the IRS. This tax return is the reason you need the ITIN. Ensure all documents are either originals or certified copies from the issuing agency.
The ITIN Renewal Application Process
The ITIN renewal process involves submitting the completed Form W-7, your original or certified identification documents, and a copy of your U.S. federal tax return to the IRS. You can submit your application directly to the IRS service center, through a Taxpayer Assistance Center (TAC) appointment, or via a Certified Acceptance Agent (CAA). Applying through a CAA like itin.net offers a streamlined process. A CAA can verify your original identification documents and forward your application package to the IRS on your behalf, often returning your original documents the same day. This method significantly reduces the risk of mail delays and document loss. The typical processing timeline for an ITIN renewal via a CAA is approximately 5–10 business days from the date the IRS receives the application. Direct applications to the IRS may take longer.
Common Mistakes for Amazon KDP Authors
Amazon KDP authors in Denmark often make specific errors during ITIN renewal. One common issue is not updating your contact information with the IRS. If the IRS sends correspondence regarding your ITIN and it goes to an outdated address, you might miss critical updates, including notices about your ITIN's status. Another mistake is failing to correctly claim treaty benefits on your tax return. While the Denmark–U.S. tax treaty allows for reduced withholding on royalties, you must properly document this on your return and potentially on Form W-8BEN submitted to Amazon. Mismatched name spellings between your identification documents, your Amazon KDP account, and your tax forms can also cause delays or rejections. Ensure consistency across all platforms and documents. Finally, many authors wait too long to check their ITIN status, only realizing it has expired when Amazon starts withholding at the highest rate.
Benefits of Using a Certified Acceptance Agent (CAA)
Using a Certified Acceptance Agent (CAA) streamlines the ITIN renewal process for Amazon KDP authors. As a CAA, itin.net can authenticate your original identification documents, such as your passport, and transmit your Form W-7 application directly to the IRS. This means you do not have to mail your original passport or other vital documents, significantly reducing the risk of them being lost or delayed in transit. CAAs are authorized by the IRS to help taxpayers with ITIN applications and renewals. They perform a crucial verification step, ensuring your application is complete and accurate before it reaches the IRS. This can lead to faster processing times, often within 5–10 business days, compared to longer waits for direct IRS submissions. For authors in Denmark, this service provides peace of mind and efficiency, allowing you to focus on your writing and publishing.
Next Steps After ITIN Renewal
Once your ITIN renewal is approved, you will receive a new ITIN or confirmation of your existing one from the IRS. You should then update your ITIN on your Amazon KDP account and ensure your W-8BEN form is current. This prevents the 30% withholding tax on future royalty payments. If you plan to conduct further business in the U.S., such as forming a U.S. LLC or opening a U.S. bank account, having a valid ITIN is often a prerequisite. For Amazon KDP authors, maintaining up-to-date tax documentation is key to a smooth and profitable publishing venture.

Practical tips
- Always use the same legal name on your Form W-7, your passport, and any prior IRS correspondence to prevent mismatches.
- Proactively check your ITIN status annually, especially if you haven't filed a U.S. tax return in three years, rather than waiting for an IRS notice.
- Ensure your tax return accompanying the Form W-7 is complete and accurate, reflecting your U.S.-sourced income and any applicable treaty benefits.
- If you are applying through a Certified Acceptance Agent, provide them with clear, unexpired identification documents to expedite the verification process.
- Keep copies of all submitted documents, including your completed Form W-7 and your renewed ITIN confirmation letter from the IRS, for your records.
Frequently asked questions
How long does ITIN renewal take for Amazon KDP authors in Denmark?
ITIN renewal typically takes 5–10 business days when processed through a Certified Acceptance Agent (CAA) like itin.net. Direct applications to the IRS may take longer.
Do I need to renew my ITIN if I haven't earned royalties in over three years?
Yes, if your ITIN has not been used on a federal tax return for three consecutive years, or if it falls within the IRS's rolling expiration schedule, it needs renewal even if you haven't earned royalties recently. Failure to renew can still lead to issues with future U.S. income.
What is the difference between an ITIN and an EIN for Amazon KDP authors?
An ITIN (Individual Taxpayer Identification Number) is for individuals who need a U.S. tax ID but do not have a Social Security Number. An EIN (Employer Identification Number) is for businesses. As an Amazon KDP author, you will primarily need an ITIN for personal tax reporting and claiming treaty benefits on royalties, unless you operate as a formal U.S. business entity.
Can I renew my ITIN by mail from Denmark without a CAA?
Yes, you can renew your ITIN by mail directly to the IRS. However, this requires you to mail original identification documents, increasing the risk of loss or delay. Using a Certified Acceptance Agent (CAA) like itin.net allows them to verify your original documents, and you avoid mailing them.
What happens if my ITIN expires and I don't renew it?
If your ITIN expires and you continue to receive U.S.-sourced income, such as Amazon KDP royalties, Amazon will likely begin withholding 30% of your earnings. You will also be unable to claim any tax treaty benefits, such as reduced withholding rates under the Denmark–U.S. tax treaty.
How do I update my ITIN with Amazon KDP after renewal?
After successfully renewing your ITIN, log in to your Amazon KDP account. Navigate to your tax information settings and update the ITIN field with your new or renewed number. Ensure your W-8BEN form is also current and reflects the valid ITIN.
