Why Substack Writers in Colombia Need an ITIN
Substack writers in Colombia face a specific hurdle when it comes to U.S. tax obligations, primarily due to how platforms like Stripe handle payments to non-U.S. individuals earning U.S. source income. While many Substack writers may not consider themselves U.S. taxpayers, receiving payments processed through U.S. financial systems often triggers reporting requirements. This means you may need an ITIN, even if you've never lived or worked in the United States. The IRS issues the ITIN to individuals who must have a U.S. taxpayer identification number but do not have and are not eligible for a Social Security number (SSN). For Substack writers in Colombia, this typically arises when your earnings are considered U.S. source income, and the payment processor (like Stripe) requires a U.S. tax ID for their own reporting obligations to the IRS. Without it, you might face backup withholding at a higher rate, impacting your net earnings significantly. Understanding this distinction is key to avoiding unexpected tax burdens and ensuring compliance with U.S. tax law.
Eligibility and Triggers for an ITIN
You generally need an ITIN if you are a non-resident alien who must file a U.S. tax return or report U.S. income, but you cannot obtain an SSN. For Substack writers in Colombia, the primary trigger is receiving payments from Substack that are classified as U.S. source income. Stripe, the payment processor commonly used by Substack, will often require a U.S. taxpayer identification number (either an SSN or an ITIN) to avoid backup withholding. This is part of their compliance with IRS regulations, such as Form 1099 reporting. If Substack classifies your earnings as U.S. income, and you do not provide a valid U.S. taxpayer ID, Stripe may be required to withhold 24% of your payments. This backup withholding applies even if you have no other U.S. tax obligations. Therefore, securing an ITIN becomes essential not just for tax filing but also to ensure you receive your full earnings without excessive withholding. The IRS Form W-7 is the application form for an ITIN. It's important to note that an ITIN is solely for tax reporting purposes; it does not grant work authorization or eligibility for Social Security benefits in the U.S.
Required Documents for Your ITIN Application
To apply for an ITIN using IRS Form W-7, you will need to provide specific documentation to prove your identity and foreign status. The IRS requires original or certified copies of supporting documents. The most commonly accepted and preferred document is your valid passport. If you do not have a passport, other documents can be used, but a passport significantly simplifies the process. Other acceptable documents include a national identity card that shows your photograph, name, and address, or a birth certificate. You must also submit a completed IRS Form W-7, signed under penalty of perjury. Crucially, you will need to include evidence of your U.S. tax filing requirement. For Substack writers, this often means attaching a U.S. tax return (such as Form 1040-NR, U.S. Nonresident Alien Income Tax Return) for the tax year you are claiming a tax credit, refund, or deduction. If you are applying for an ITIN to comply with payment processor requirements like Stripe's, you may need to attach a statement explaining this need, along with the relevant tax return. Ensure all documents are either originals or certified copies from the issuing agency. If documents are not in English, they must be accompanied by a certified English translation.
The ITIN Application Process
Applying for an ITIN involves several distinct steps. First, you must accurately complete IRS Form W-7. This form requires information about your personal details, your reason for applying for an ITIN, and your U.S. tax obligations. Ensure all fields are filled out correctly, as errors can lead to delays or rejection. Second, gather your supporting documentation. This includes your valid passport (or other acceptable identification) and any required tax returns or statements explaining your need for an ITIN. Third, you must choose an application method. You can mail your application directly to the IRS, apply through a Certified Acceptance Agent (CAA), or visit an IRS Taxpayer Assistance Center (TAC) that offers ITIN services. For most applicants, especially those outside the U.S., using a CAA is the most efficient and secure method. A CAA, like itin.net, can verify your original documents and forward your application to the IRS, eliminating the risk of mailing your original passport. The typical processing timeline for an ITIN application submitted through a CAA is 5–10 business days from when the IRS receives it. If you mail your application directly to the IRS, processing can take much longer, often 8–11 weeks, and you risk losing your original documents during transit.
Common Mistakes for Substack Writers in Colombia
Substack writers in Colombia often encounter specific pitfalls when applying for an ITIN. One common mistake is failing to correctly identify the reason for applying on Form W-7. Many writers mistakenly select 'Other' when their situation clearly falls under a specific category related to U.S. income or tax filing requirements due to payment processors. Another frequent error involves incomplete or inaccurate supporting documentation. This includes submitting photocopies instead of original or certified documents, or failing to include the required U.S. tax return when applying for an ITIN to meet payment platform requirements. Missing the tax return is a very common reason for Form W-7 rejection. Furthermore, discrepancies in personal information between your Form W-7, your passport, and any other identification can cause significant delays. Ensure your legal name, date of birth, and place of birth are identical across all documents. Lastly, not understanding the implications of U.S. source income can lead to delayed applications. If Stripe or Substack informs you that you need an ITIN to avoid backup withholding, this is a direct trigger to apply, and your application should reflect this requirement clearly.
The Certified Acceptance Agent (CAA) Advantage
Applying for an ITIN through a Certified Acceptance Agent (CAA) offers distinct advantages, especially for individuals outside the United States. As an authorized CAA, itin.net can authenticate your original identification documents, such as your passport, and transmit them directly to the IRS. This means you do not have to mail your original passport or other vital documents to the IRS, significantly reducing the risk of loss or damage during transit. The CAA process also expedites the initial review of your application. We meticulously check your Form W-7 and supporting documents for completeness and accuracy before submission. This pre-screening helps to minimize errors that could lead to delays or rejection by the IRS. While the IRS still performs the final review and ITIN assignment, the CAA's involvement ensures your application is submitted correctly from the start. The typical processing time when using a CAA is substantially faster than mailing directly to the IRS, often within 5–10 business days after the IRS receives the application package. This efficiency is particularly valuable for Substack writers in Colombia who need their ITIN promptly to avoid higher backup withholding rates from platforms like Stripe.
Next Steps After Obtaining Your ITIN
Once you receive your ITIN from the IRS (usually via IRS letter CP-565), you can use it for your U.S. tax filing obligations and to provide to payment processors like Stripe. Ensure you provide your ITIN to Substack or Stripe as soon as possible to update your tax information and stop any applicable backup withholding. If you filed a U.S. tax return with your Form W-7 application, you should also receive any refund due to you, or you will have met your filing obligation. Remember that an ITIN is valid for seven years unless the IRS issues an earlier expiration notice. You will need to renew your ITIN if you continue to have U.S. tax obligations. For Substack writers in Colombia, this means staying updated on U.S. tax regulations and ensuring continued compliance. If you anticipate complex tax situations or need assistance with subsequent filings, consider consulting with a tax professional specializing in U.S. expatriate or non-resident taxation.

Practical tips
- Use the exact same legal name on your Form W-7 as it appears on your passport or other primary identification document to avoid mismatches.
- If your primary identification is not a passport, ensure any alternative document (like a national ID card) contains your photograph, name, address, and date of birth.
- Attach a complete U.S. tax return (e.g., Form 1040-NR) to your Form W-7 application if you are applying due to a U.S. tax filing requirement, not just to avoid backup withholding.
- When applying as a dependent or third-party designee, ensure all required signatures and documentation for that specific status are included on Form W-7.
- Keep a copy of your submitted Form W-7 and all supporting documents for your records before sending them to the IRS or a Certified Acceptance Agent.
Frequently asked questions
Do I need an ITIN if I only receive payments from Substack and live in Colombia?
You likely need an ITIN if Substack or its payment processor (like Stripe) classifies your earnings as U.S. source income and requires a U.S. taxpayer identification number to avoid backup withholding. Without an ITIN, you may face a 24% withholding tax on your earnings.
Can I use my Colombian national ID card to apply for an ITIN?
A Colombian national ID card can be used as a supporting identification document for an ITIN application if it includes your photograph, name, address, and date of birth. However, a valid passport is the preferred document and simplifies the process.
How long does it take to get an ITIN as a Substack writer in Colombia?
Applying through a Certified Acceptance Agent (CAA) like itin.net typically results in an ITIN within 5-10 business days after the IRS receives your application. Mailing directly to the IRS can take 8-11 weeks.
What is the difference between an ITIN and an EIN for a Substack writer?
An ITIN (Individual Taxpayer Identification Number) is for individuals, used for personal U.S. tax reporting. An EIN (Employer Identification Number) is for businesses, used to identify entities. As a Substack writer earning freelance income, you will typically need an ITIN, not an EIN, unless you form a U.S. business entity.
Do I need to file a U.S. tax return to get an ITIN?
Not always. You can apply for an ITIN if you are required to file a U.S. tax return (e.g., Form 1040-NR), or if you need it to comply with other tax requirements, such as backup withholding by a payment processor. In the latter case, you may need to submit a statement explaining the requirement along with your Form W-7, rather than a full tax return.
What happens if I don't get an ITIN and Stripe withholds taxes?
If Stripe withholds 24% of your Substack earnings due to lack of a U.S. taxpayer ID, you can still file a U.S. tax return (Form 1040-NR) with an ITIN to claim a refund of the excess withholding, provided you have no actual U.S. tax liability or your tax liability is less than the amount withheld.
