Substack Writers in Denmark Face Unique EIN Requirements
As a Substack writer based in Denmark, you may encounter specific situations requiring a U.S. Employer Identification Number (EIN). Unlike U.S. residents, non-residents often face more complex requirements for U.S. tax identification. For many Denmark-based Substack writers, the primary trigger for needing an EIN is the payout system used by platforms like Stripe. Stripe, processing payments for many content creators, requires a U.S. tax identification number for reporting purposes, especially when earnings reach certain thresholds or for non-U.S. persons receiving U.S.-sourced income. Without an EIN, you might face backup withholding at a higher rate, impacting your net earnings. This situation is distinct from U.S. citizens who might need an EIN for broader business operations like hiring or opening a U.S. bank account under a U.S. business entity. Your need is primarily driven by international tax reporting obligations tied to your content monetization activities in the U.S. market.
When You Need an EIN as a Denmark-Based Substack Writer
The necessity of an EIN for Substack writers in Denmark typically arises from the payment processing infrastructure. If you receive payments through Stripe, or similar U.S.-based platforms, and you are not a U.S. resident, you will likely need to provide a U.S. tax identification number. This is to comply with U.S. tax reporting regulations, particularly concerning payments made to foreign individuals. While not always mandatory for simply earning income, failing to provide an EIN when requested by a payment processor like Stripe can lead to increased backup withholding taxes on your earnings. This backup withholding rate for non-U.S. persons can be as high as 30% unless reduced by a tax treaty. The Denmark-U.S. tax treaty may offer relief, but obtaining an EIN is often the most straightforward way to manage these reporting requirements and potentially reduce withholding. Furthermore, if you are structuring your Substack earnings through a U.S. entity, such as a U.S. LLC, an EIN is mandatory for that entity, regardless of your residency.
Essential Documents for Your EIN Application
Applying for an EIN as a non-resident requires specific documentation to verify your identity and your business or individual status. The primary document you will need is the EIN application form, IRS Form SS-4. For non-U.S. residents, this form must be completed accurately, paying close attention to line 7b, where you must write 'Foreign' if you do not have a U.S. Social Security Number (SSN) or Individual Taxpayer Identification Number (ITIN). Beyond Form SS-4, the responsible party applying for the EIN must provide identification. This typically means a copy of your passport. If you are applying on behalf of a U.S. entity (even if you are a foreign owner), you may also need to provide formation documents for that entity. These could include articles of incorporation or an Operating Agreement if you have formed a U.S. LLC. While a U.S. business address is often listed on Form SS-4, non-residents can sometimes use a mail forwarding service or the address of their U.S. representative. Ensure all documents are clear, legible, and accurately reflect the information provided on Form SS-4.
The EIN Application Process for Non-Residents
The process for obtaining an EIN as a non-resident differs significantly from that for U.S. residents. U.S. residents can often apply online and receive an EIN within 1–2 business days. However, non-residents typically cannot use the online portal, as it requires a U.S. SSN or ITIN. The standard method for non-residents is to submit Form SS-4 via fax or mail directly to the IRS. This process can take considerably longer, often ranging from 3–5 weeks. Upon successful processing, the IRS will mail your EIN confirmation letter, known as CP-575, to the address listed on your application. It is crucial to ensure this address is a reliable point of contact for receiving U.S. mail or to arrange for mail forwarding. The IRS does not provide EINs over the phone to non-residents. Due to the extended processing times and the need for accurate documentation, many non-residents opt for expedited services.
Common Pitfalls for Denmark-Based Substack Writers
Substack writers in Denmark often encounter specific application errors when applying for an EIN. A frequent mistake is incorrectly filling out line 7b of Form SS-4. If you do not possess a U.S. SSN or ITIN, you must write 'Foreign' in this field. Leaving it blank or entering incorrect information can lead to application rejection. Another common issue is the lack of a valid U.S. business address. While you may not have a physical presence in the U.S., you need a reliable address for receiving IRS correspondence. Using a personal Danish address is generally not acceptable for this purpose. Some writers mistakenly believe they can apply online, but this is usually only an option for those with an SSN or ITIN. Applying through the wrong channel can result in delays or outright failure. Finally, ensure the responsible party's name and identification match exactly across all submitted documents; discrepancies can cause significant processing delays. For those forming a U.S. LLC to receive their Substack income, errors in entity type selection on Form SS-4 or missing an Operating Agreement are also critical mistakes.
How a Certified Acceptance Agent (CAA) Streamlines the Process
For non-residents seeking an EIN, the traditional IRS fax or mail application can be lengthy. A more efficient route is through a Certified Acceptance Agent (CAA). As a CAA, itin.net can verify your identity and application details in person, significantly speeding up the process. When you apply through a CAA like itin.net, your application is reviewed and submitted with a higher degree of accuracy, reducing the chances of rejection due to common errors. The CAA acts as an intermediary, confirming your documentation and ensuring that Form SS-4 is filled out correctly before it is sent to the IRS. This service is particularly valuable for Denmark-based writers who may not be familiar with U.S. tax forms or the nuances of IRS procedures. Using a CAA typically shortens the EIN acquisition time to a matter of business days, compared to several weeks via direct mail or fax to the IRS. This expedited service allows you to meet platform requirements and manage your tax obligations more promptly.
Next Steps After Obtaining Your EIN
Once you have successfully obtained your EIN, you can proceed with setting up your payment systems and ensuring tax compliance. For Substack writers in Denmark, this often means updating your payment profile with Stripe or any other platform you use. Providing your new EIN will prevent or stop backup withholding, ensuring you receive your full earnings. If you established a U.S. LLC or another U.S. business entity to receive your Substack income, you will need to use your EIN for all federal tax filings, including filing Form 5472 if you are a foreign-owned U.S. disregarded entity. This form is crucial for reporting transactions between the U.S. entity and its foreign owner. You may also consider opening a U.S. bank account to manage your business finances separately. This can simplify bookkeeping and make it easier to comply with U.S. tax obligations.

Frequently asked questions
Do I need an EIN if I'm a Danish citizen writing on Substack and only paid via PayPal?
If you are paid via PayPal and are not a U.S. resident, PayPal may still require a U.S. tax identification number for reporting purposes, especially as your income grows. While the requirements can vary by platform, obtaining an EIN is often the most proactive step to avoid issues and potential backup withholding.
Can I use my Danish business address on Form SS-4?
No, you generally cannot use your Danish business address on Form SS-4 for an EIN application. You need a U.S. address for receiving IRS correspondence. This can be a mail forwarding service or the address of a U.S. representative.
How long does it take for a non-resident to get an EIN by fax?
Applying by fax can take approximately 3–5 weeks for the IRS to process an EIN application for a non-resident. This timeframe can vary depending on IRS workload and accuracy of the submitted application.
Is the Denmark-U.S. tax treaty relevant for my EIN application?
The Denmark-U.S. tax treaty is primarily relevant for determining the rate of U.S. withholding tax on your Substack earnings, not directly for the EIN application itself. However, having an EIN can help you benefit from treaty provisions by ensuring accurate reporting and potentially reduced withholding rates, often requiring specific forms like W-8BEN.
What is the difference between an ITIN and an EIN for a Substack writer?
An ITIN (Individual Taxpayer Identification Number) is for individuals who need a U.S. tax ID but do not qualify for an SSN. An EIN (Employer Identification Number) is for businesses and business-related tax reporting. As a Substack writer, you might need an ITIN if you have U.S. tax filing obligations as an individual, or an EIN if you are operating as a business entity or need it for payment processor compliance.
Can a Certified Acceptance Agent (CAA) help me get an EIN faster?
Yes, a Certified Acceptance Agent (CAA) can significantly speed up the EIN application process for non-residents. They verify your application details and submit them to the IRS, often reducing the processing time from weeks to just a few business days. itin.net operates as a CAA.
