Substack Writers in Mongolia Face Unique EIN Challenges
Substack writers in Mongolia face a specific hurdle when their writing income streams necessitate a U.S. Employer Identification Number (EIN). Unlike U.S. residents who can often apply online, non-residents without a Social Security Number (SSN) or Individual Taxpayer Identification Number (ITIN) must navigate a more complex, manual application process. This is particularly relevant for Substack writers who receive payouts via Stripe, as Stripe requires accurate tax information, often including an EIN, for compliance. The friction point arises because Substack operates within the U.S. financial system, and receiving regular income from U.S.-based platforms triggers reporting requirements that necessitate a U.S. tax ID. For a writer in Mongolia, this means understanding the IRS's specific procedures for international applicants, which differ significantly from domestic ones. The process involves Form SS-4, the application for an EIN, and requires careful attention to detail to avoid delays or rejections. Understanding these distinctions is the first step toward securing the necessary EIN for your Substack income.
When You Need an EIN for Substack Income
An EIN is required for your Substack income if you are operating as a U.S. business entity, such as a U.S. LLC, or if you are receiving payments that require tax reporting by the payer. For Substack writers, especially those in Mongolia, this typically comes into play when payment processors like Stripe require a U.S. tax identification number for 1099-K reporting or similar compliance measures. Even if you operate as a sole proprietor in Mongolia, receiving substantial income from a U.S. platform can trigger reporting obligations. If you have formed a U.S. LLC to manage your Substack business, an EIN is mandatory to open a U.S. bank account and operate the business. Without an EIN, you may encounter issues with payment processing, banking, and U.S. tax compliance, potentially leading to withheld payments or penalties. It is not optional if you are structuring your writing business to interact with the U.S. financial system.
Required Documents for EIN Application
Applying for an EIN as a non-resident without an SSN involves specific documentation. The primary form is the IRS Form SS-4, Application for Employer Identification Number. This form requires details about your business, including its name, address, and the type of entity. For non-residents, line 7b of Form SS-4 is critical; you must write 'Foreign' in the SSN/ITIN field if you do not possess one. Beyond Form SS-4, you will need a copy of the passport of the responsible party applying for the EIN. If you have formed a U.S. LLC, you must also provide your business formation documents, such as the Articles of Organization. A U.S. business address is also required; this can be a physical address or a mail forwarding service. Ensure all documents are clear, legible, and accurately reflect the information provided on Form SS-4. Mismatched information is a common reason for application delays.
The EIN Application Process for Non-Residents
The process for obtaining an EIN as a non-resident in Mongolia differs significantly from that for U.S. residents. Since you likely do not have an SSN and cannot use the IRS's online application portal, the application is typically submitted by fax or mail. After completing Form SS-4, you will fax it to the IRS. The IRS will then review your application and, if approved, will mail your EIN confirmation letter (CP-575) to the U.S. business address you provided. This mailing process can take several weeks. For non-residents, the typical timeline for receiving an EIN via fax is 3–5 weeks. This longer processing window is due to manual review and the international mail delivery time. It is crucial to fill out Form SS-4 completely and accurately to avoid any delays in this already extended timeframe. Confirming the U.S. business address is a valid mailing address for IRS correspondence is also essential.
Common Mistakes for Substack Writers in Mongolia
Substack writers in Mongolia often encounter specific pitfalls when applying for an EIN. A frequent error is attempting to use the online application portal, which is designed for applicants with an SSN or ITIN and will reject non-residents. Another common mistake is incorrectly filling out line 7b of Form SS-4; if you do not have an SSN or ITIN, you must explicitly write 'Foreign' in that field, not leave it blank or enter any other identifier. Choosing the wrong entity type on the SS-4 can also lead to complications down the line, impacting your U.S. tax obligations. Some writers mistakenly believe an EIN is not necessary if they are only receiving income from Substack, overlooking the reporting requirements of payment processors like Stripe. Ensuring your U.S. business address is a reliable mail-receiving point is also vital, as the IRS sends the EIN confirmation via postal mail.
How a Certified Acceptance Agent (CAA) Helps
A Certified Acceptance Agent (CAA) can streamline the EIN application process for non-residents, including Substack writers in Mongolia. As a CAA, itin.net acts as an intermediary between you and the IRS. Instead of faxing your application directly and waiting several weeks for a response, a CAA can submit the Form SS-4 on your behalf electronically or via fax, often expediting the process. More importantly, a CAA can verify your identity and business documents in person or remotely, reducing the risk of errors and ensuring the application meets IRS standards. This verification step is crucial for non-residents who lack an SSN. While the IRS still handles the final EIN issuance, working with a CAA like itin.net can significantly reduce the processing time, typically to 1–2 business days for an EIN once the application is submitted correctly. This faster turnaround allows you to open your U.S. bank account and manage your Substack income more efficiently. The expedited channel through a CAA typically costs more, reflecting the added service and speed. itin.net offers this service for non-residents.
Next Steps After Obtaining Your EIN
Once you receive your EIN confirmation (CP-575) from the IRS, the next critical step is to open a U.S. bank account. A U.S. bank account is essential for managing your Substack income and any business expenses efficiently. Services like Mercury, Relay, or Brex are popular choices for international founders. This account will allow you to receive Stripe payouts directly and manage your finances separate from your personal accounts. You will also need to consider U.S. tax filing obligations, especially if you formed a U.S. LLC. This may involve filing forms like Form 5472 to report transactions between your U.S. LLC and your foreign-owned business. Given the complexities of U.S. tax law for non-residents, consulting with a qualified tax professional or attorney specializing in international business is highly recommended.

Practical tips
- Write 'Foreign' in the SSN/ITIN field (line 7b) on Form SS-4 if you do not have an SSN or ITIN. Leaving it blank or entering incorrect information will cause delays.
- Use a reliable U.S. business address for mail forwarding. The IRS will mail your EIN confirmation letter (CP-575) to this address, and delays in receiving it can impede opening a bank account.
- Ensure the legal name of the responsible party on Form SS-4 exactly matches their passport or other identification. Any discrepancies can lead to rejection.
- If you are forming a U.S. LLC, ensure your Operating Agreement and formation documents are in order before applying for the EIN. The IRS may request these.
- Understand that the standard processing time for non-residents via fax is 3–5 weeks. Factor this into your financial planning and Stripe payout requirements.
Frequently asked questions
Do I need an EIN if I'm a sole proprietor in Mongolia earning Substack income?
If your Substack income is paid via U.S. platforms like Stripe, and they require a U.S. tax ID for reporting purposes (like a 1099-K), you will likely need an EIN. This is separate from your Mongolian tax obligations. Operating as a sole proprietor without forming a U.S. entity means you'll use your personal name on the SS-4, but an EIN is still necessary for U.S. platform compliance.
Can I apply for an EIN online as a writer in Mongolia?
No, non-residents applying for an EIN who do not have an SSN or ITIN cannot use the IRS's online application portal. The online system is designed for U.S. residents. You must use the fax or mail method for Form SS-4, or utilize a Certified Acceptance Agent (CAA) like itin.net for expedited processing.
How long does it take to get an EIN without an SSN?
For non-residents applying via fax directly to the IRS, the typical processing time is 3–5 weeks. If you use a Certified Acceptance Agent (CAA) like itin.net, the process can be significantly faster, often resulting in an EIN within 1–2 business days after the application is submitted correctly.
What is the cost of getting an EIN for a non-resident?
The IRS does not charge a fee to apply for an EIN. However, if you use a service like itin.net, which acts as a Certified Acceptance Agent (CAA), there is a service fee. The itin.net Standard EIN service for non-residents is priced at $297, reflecting the expedited processing and verification services provided.
Can I use a virtual U.S. address for my EIN application?
Yes, you can use a U.S. business address for mail forwarding services for your EIN application. This is crucial because the IRS will mail your EIN confirmation letter (CP-575) to the U.S. address provided on Form SS-4. Ensure the address is reliable and can receive mail promptly.
What if I already have an ITIN, can I apply online for an EIN?
If you have an ITIN, you may be able to apply for an EIN online. However, the IRS system can sometimes be sensitive. Many non-residents find it more reliable to still use the fax method or a Certified Acceptance Agent (CAA) to ensure the application is processed without issues, especially when dealing with foreign-owned businesses.
