Substack Writers in Romania Face Unique Tax Hurdles

Substack writers in Romania encounter a specific challenge when receiving payments from US-based platforms like Substack, especially when those payments are processed via Stripe. These platforms often require a U.S. taxpayer identification number for accurate tax reporting. For individuals who are not U.S. citizens or residents, this typically means obtaining an ITIN (Individual Taxpayer Identification Number). Unlike U.S. citizens who use a Social Security Number (SSN), non-residents without an SSN must apply for an ITIN to comply with IRS regulations. This process is essential for correctly reporting income earned from U.S. sources and avoiding potential penalties. The need arises because U.S. tax law requires reporting of income paid to non-residents, and platforms like Substack, using payment processors like Stripe, must provide tax forms (such as Form 1099 or 1042-S) to both the recipient and the IRS. Without a U.S. taxpayer ID, these payments may be subject to higher backup withholding rates, impacting your net earnings significantly.

When You Need an ITIN as a Romanian Substack Writer

An ITIN is required for Romanian Substack writers when they receive income from U.S. sources and do not have, and are not eligible for, a Social Security Number (SSN). This scenario commonly occurs when Substack, operating through U.S. payment processors, needs to issue tax documentation. The IRS mandates that platforms report payments made to non-residents. If you are a Romanian resident earning income through Substack, you will likely receive a request from Substack or its payment processor to provide a U.S. taxpayer identification number. This is often to complete forms like Form W-8BEN (Certificate of Foreign Status of Beneficial Owner for United States Tax Withholding and Reporting) or, if you have U.S. tax filing obligations beyond simple treaty benefits, potentially requiring an ITIN for a Form 1040-NR (U.S. Nonresident Alien Income Tax Return). The Romania–U.S. tax treaty may offer benefits, but claiming them often necessitates proper identification with the IRS through an ITIN if you are filing a tax return. Even if you don't have a U.S. tax filing obligation, Substack might require an ITIN for their reporting purposes to avoid backup withholding.

Required Documents for Your ITIN Application

To apply for an ITIN, you must complete Form W-7, Application for IRS Individual Taxpayer Identification Number. This form requires detailed personal information, including your name, foreign address, and U.S. taxpayer identification number (if applicable, which it won't be if you're applying for your first ITIN). Accompanying the Form W-7 are original or certified copies of documents proving your identity and foreign status. The most commonly accepted document for identity and foreign status is a valid passport. If you do not have a passport, other documents like a national identity card with a photograph, a birth certificate, or a driver's license can be used, but they must be accompanied by a secondary identification document. For example, a national identity card would need to be presented alongside a foreign driver's license. Each document must clearly show your name, photograph, address, date of birth, and expiration date. Ensure all submitted documents are valid and not expired.

The ITIN Application Process: A Step-by-Step Guide

The application process for an ITIN begins with correctly filling out Form W-7. This form requires your full legal name, mailing address, date of birth, and country of citizenship. You must also provide the required identity and foreign status documents, either as originals or certified copies from the issuing agency. Once Form W-7 and your supporting documents are ready, you have three main options for submission. You can mail them directly to the IRS in Austin, Texas, but this involves sending original documents and can lead to long processing times, often several months. Alternatively, you can use the services of a Certified Acceptance Agent (CAA), like itin.net. A CAA can verify your original documents and forward your application to the IRS, meaning you get your documents back the same day. This is the fastest and most secure method. The third option is to apply in person at a designated IRS Taxpayer Assistance Center (TAC) that offers ITIN application services, though appointments are often required and document verification procedures may vary. The typical timeline when using a CAA is 5–10 business days from application submission to receiving your ITIN from the IRS.

Common Mistakes for Romanian Substack Writers

Romanian Substack writers often make specific errors when applying for an ITIN. One frequent mistake is an incomplete Form W-7, particularly missing information related to U.S. tax law or treaty benefits, even if indirectly related to their income source. Another common pitfall is failing to provide sufficient documentation or submitting photocopies instead of originals or certified copies when not using a Certified Acceptance Agent (CAA). For instance, submitting a non-Romanian national ID without proper accompanying documents can cause delays. Mismatched names between your identification documents and the Form W-7 are also problematic; ensure your legal name is consistent everywhere. Lastly, incorrect claims regarding tax treaty benefits, if applicable to your specific income situation, can lead to rejection or further IRS inquiry. Confirming your residency status and eligibility for any treaty provisions before applying is crucial.

Benefits of Using a Certified Acceptance Agent (CAA)

Utilizing a Certified Acceptance Agent (CAA) like itin.net offers significant advantages for Romanian Substack writers applying for an ITIN. The primary benefit is that a CAA can verify your original identification documents (like your passport) on behalf of the IRS. This means you do not have to mail your original, irreplaceable documents to the IRS, avoiding the risk of loss or damage during transit. The CAA performs the verification and returns your documents to you immediately after processing your application. This dramatically speeds up the process; while direct mailing can take many months, applications submitted through a CAA are typically processed by the IRS within 5–10 business days. Furthermore, CAAs are trained by the IRS to correctly complete the Form W-7 and ensure all required supporting documentation is present and accurate, reducing the likelihood of application errors and rejections. This streamlined approach provides peace of mind and a faster path to obtaining your ITIN.

Next Steps After Obtaining Your ITIN

Once you receive your ITIN from the IRS, you can use it to complete tax forms required by Substack and its payment processors, such as Form W-8BEN, or to file your U.S. tax return (e.g., Form 1040-NR) if necessary. This allows you to report your income accurately and potentially benefit from tax treaty provisions between Romania and the U.S. If you are setting up a U.S. business entity, such as a U.S. LLC, you may also need an EIN (Employer Identification Number) for that entity, which is a separate application process. For Romanian writers, ensuring correct tax compliance for U.S.-sourced income is vital for sustained earnings. If you are unsure about your specific tax obligations or the application process, it is advisable to consult with a qualified tax professional.

Practical tips

  • Use your full legal name exactly as it appears on your passport or other primary identification document on Form W-7.
  • Ensure you submit original documents or certified copies from the issuing agency when applying via mail or at an IRS TAC. A Certified Acceptance Agent can verify your original documents, eliminating the need to mail them.
  • Double-check the U.S. address you provide on Form W-7. This is where the IRS will mail your ITIN assignment letter (CP-565).
  • If you are claiming tax treaty benefits, ensure you understand which article of the treaty applies to your income type and accurately indicate this on Form W-7.
  • Keep a copy of your submitted Form W-7 and all supporting documents for your records, as well as the IRS ITIN assignment letter once received.

Frequently asked questions

Do I need an ITIN if I'm a Substack writer in Romania and get paid through Stripe?

Yes, if Substack or its payment processor (like Stripe) requires a U.S. taxpayer identification number for tax reporting purposes and you do not have an SSN, you will need an ITIN. This is common for non-residents earning U.S. income.

What is the fastest way for a Romanian resident to get an ITIN?

The fastest method is typically through a Certified Acceptance Agent (CAA). A CAA can verify your original documents on the spot and submit your application directly, often resulting in ITIN issuance within 5–10 business days. Mailing documents directly to the IRS can take several months.

Can I use my Romanian national ID card to apply for an ITIN?

A Romanian national ID card can be used as a supporting identification document, but it usually needs to be presented along with another form of identification that includes a photograph, such as a passport or driver's license, especially if applying in person or via a CAA. A passport is the preferred primary document.

How long does it take to get an ITIN?

When applying through a Certified Acceptance Agent (CAA), the typical processing time is 5–10 business days after your application is submitted. If you mail your application directly to the IRS, it can take significantly longer, often several months.

What happens if I don't have an ITIN and Substack requires one?

If Substack or its payment processor requires a U.S. taxpayer identification number and you don't provide one, your payments may be subject to backup withholding at a higher rate (often 24% or more). This means less money reaches you. You may also be unable to claim benefits under the Romania–U.S. tax treaty without proper IRS identification.

Do I need an ITIN if I'm forming a U.S. LLC as a Romanian resident?

While an ITIN is for individuals, if you are forming a U.S. LLC and it will have U.S. tax reporting obligations (e.g., filing Form 5472), you or a responsible party associated with the LLC may need an ITIN. The LLC itself would typically need an EIN.
