Why Authors in Iceland Need an ITIN for U.S. Royalties
U.S. publishers paying royalties to non-resident authors are required by the IRS to withhold 30% of the payment. This withholding applies unless the author provides a valid IRS Taxpayer Identification Number (TIN) and potentially claims a reduced rate under an applicable tax treaty. For authors based in Iceland, who do not qualify for a Social Security Number (SSN), the Individual Taxpayer Identification Number (ITIN) is the required TIN. Without an ITIN, you face a significant reduction in your royalty income due to this mandatory 30% U.S. tax withholding. The U.S. has a tax treaty with Iceland, which can reduce this withholding rate, often to 0% or 10%, but claiming these treaty benefits necessitates having an ITIN and correctly completing IRS forms. This process is distinct from general U.S. tax obligations and is specifically triggered by the receipt of U.S.-sourced income, such as book royalties paid by a U.S. entity.
ITIN Eligibility and Triggers for Icelandic Authors
You are generally required to obtain an ITIN if you are a non-resident alien who needs to file a U.S. tax return or has U.S. tax liability, and you are not eligible for an SSN. For authors receiving book royalties from U.S. publishers, the trigger is the payment itself. U.S. payers are obligated to report these payments to the IRS and must have your correct TIN on file to apply any reduced withholding rates under the U.S.-Iceland tax treaty. Failure to provide an ITIN means the default 30% withholding rate will be applied. Furthermore, if you have other U.S. income streams or U.S. business activities, an ITIN might be necessary for filing your U.S. tax return (e.g., Form 1040-NR). The IRS Form W-7 is used to apply for an ITIN, and it must be submitted with a valid federal tax return or a statement explaining why a tax return is not required.
Required Documents for Your ITIN Application
To apply for an ITIN, you must complete and submit IRS Form W-7, Application for IRS Individual Taxpayer Identification Number. This form requires your full legal name, foreign address, and details about your U.S. income. Alongside the W-7, you must provide original identification documents or certified copies from the issuing agency to prove your identity and foreign status. The IRS prefers a valid, unexpired passport as the primary identification document. If a passport is not available, other documents like a national identity card, a driver's license, or a birth certificate may be accepted, provided they meet specific IRS criteria. It is also necessary to include a copy of the U.S. federal tax return you are filing, or a statement explaining why you are exempt from filing. For authors receiving royalties, this typically means attaching the relevant tax return that reports the royalty income and claims treaty benefits.
The ITIN Application Process for Icelandic Authors
The process for obtaining an ITIN begins with completing IRS Form W-7. You can submit your application directly to the IRS by mail, or you can use the services of a Certified Acceptance Agent (CAA). Mailing your application directly to the IRS means sending your original identification documents, which carries the risk of loss or delay. The IRS processing times for mail-in applications can be lengthy, often taking several weeks or even months. A more efficient and secure method is to apply through a CAA, such as itin.net. A CAA can verify your original identification documents and forward your application to the IRS. When applying through a CAA, the typical timeline for receiving your ITIN is significantly shorter, usually within 5–10 business days after the application is submitted to the IRS. The IRS will issue a CP-565, Notice of ITIN Assignment, once your application is approved.
Common Mistakes for Authors Receiving Icelandic Royalties
Authors receiving book royalties from the U.S. can make specific errors on their ITIN applications. One common mistake is failing to correctly claim tax treaty benefits; this requires referencing the correct article of the U.S.-Iceland tax treaty on your tax return and W-7. Another pitfall is submitting incomplete or inaccurate information on Form W-7, such as mismatched names or incorrect foreign addresses. Some authors mistakenly believe they can use a previous year's tax return if they are applying for the current year; however, the W-7 generally requires the tax return for the year in which the income was received or the year for which the ITIN is needed. Ensure all supporting documents are valid and clearly legible. If you are mailing originals, ensure they are properly secured and trackable. For those using a CAA, ensure the agent is legitimate and follows IRS procedures.
How a Certified Acceptance Agent (CAA) Streamlines the Process
Applying for an ITIN via a Certified Acceptance Agent (CAA) offers distinct advantages for authors. CAAs are individuals or entities authorized by the IRS to assist applicants in obtaining ITINs. Unlike mailing your original documents directly to the IRS, a CAA can authenticate your identity documents, such as your passport. This means you do not have to send your valuable originals through the mail, reducing the risk of loss or damage. The CAA reviews your application for completeness and accuracy before submitting it to the IRS. This pre-screening significantly lowers the chance of your application being rejected due to common errors. For authors in Iceland, utilizing a CAA like itin.net can expedite the process, as CAAs often have direct communication channels with the IRS and a streamlined submission process, leading to faster ITIN issuance, typically within 5–10 business days.
Next Steps After Receiving Your ITIN
Once you receive your ITIN from the IRS (usually via a CP-575 notice), you can provide it to your U.S. publishers. This allows them to update their records and apply the correct, potentially reduced, tax withholding rates based on the U.S.-Iceland tax treaty. You will also use your ITIN for any future U.S. tax filings. If you plan to establish a U.S. business entity, such as a U.S. LLC, an ITIN may be a prerequisite for certain business activities or bank account openings, though an EIN is typically required for the business itself. For authors who anticipate ongoing U.S. royalty income, ensuring your ITIN is current and correctly associated with your tax filings is essential.

Practical tips
- Use the same legal name across Form W-7, your passport, and any prior IRS correspondence — mismatched name fields are a common reason for ITIN application rejection.
- Carefully review the U.S.-Iceland tax treaty to identify the correct article and reduced withholding rate applicable to your book royalty income; misapplication can lead to incorrect tax filings.
- When applying via a Certified Acceptance Agent (CAA), ensure they are an authorized agent and understand their process for document verification and submission to the IRS.
- If you are also considering forming a U.S. LLC for your publishing activities, ensure you understand the requirements for both an ITIN for personal tax matters and an EIN for business operations.
- Keep copies of all submitted documents, including your completed Form W-7 and the tax return, for your records. This is vital for future reference and potential IRS inquiries.
Frequently asked questions
Do U.S. publishers always withhold 30% on royalties paid to Icelandic authors?
U.S. publishers are required to withhold 30% on royalties paid to non-resident aliens unless the recipient provides a valid U.S. Taxpayer Identification Number (like an ITIN) and claims treaty benefits. The U.S. has a tax treaty with Iceland that can reduce this rate, but you must have an ITIN to claim it.
Can I use my Icelandic national identification number instead of an ITIN?
No, your Icelandic national identification number is not a U.S. Taxpayer Identification Number. The IRS requires a U.S. TIN, which for individuals not eligible for an SSN is an ITIN, to process U.S. tax obligations and apply treaty benefits.
How long does it take to get an ITIN once I submit my application?
If you mail your application directly to the IRS, it can take several weeks to months. When you apply through a Certified Acceptance Agent (CAA) like itin.net, the process is typically much faster, with ITINs often issued within 5–10 business days after submission to the IRS.
What is the difference between an ITIN and an EIN for authors?
An ITIN (Individual Taxpayer Identification Number) is for individuals who have U.S. tax filing requirements but are not eligible for an SSN. An EIN (Employer Identification Number) is for businesses, such as a U.S. LLC or corporation, to identify the business entity for tax purposes. Authors typically need an ITIN for personal royalty income and may need an EIN if they form a business entity.
Can I claim the U.S.-Iceland tax treaty benefits without an ITIN?
No, you generally cannot claim reduced tax rates under the U.S.-Iceland tax treaty without a valid U.S. Taxpayer Identification Number, such as an ITIN. The IRS requires this number to properly apply treaty provisions and reduce the mandatory withholding on your royalty income.
What if my passport has expired but is still valid for identification purposes?
The IRS requires a valid, unexpired identification document. If your passport has expired, it cannot be used to prove identity for an ITIN application. You will need to use another acceptable identification document or renew your passport.
