ITIN Application for Foreign Entrepreneurs — Doral Miami Guide 2026

What Is an ITIN and Who Needs One?

An ITIN is a 9-digit number that begins with the digit 9 (format: 9XX-XX-XXXX). It is issued exclusively by the IRS for federal tax processing purposes. Unlike an EIN (Employer Identification Number, which belongs to your LLC), an ITIN belongs to you personally as the foreign individual owner or responsible party.

Foreign entrepreneurs with a Florida LLC typically need an ITIN when: their LLC is taxed as a pass-through entity (single-member or partnership) and they must file a personal US return; they receive US-source income subject to withholding; they want to claim reduced withholding under a tax treaty; or certain financial institutions require it for account opening. Note that an ITIN does not authorize employment in the US and cannot be used in place of an SSN for employment purposes.

If your LLC already has an EIN and you only need to satisfy business-level filing requirements, you may not need a personal ITIN. Consult a US CPA to determine your exact requirements. Our team at Work Together Center can refer you to bilingual CPAs in the Doral area. See our FAQ page for more.

How to Apply for an ITIN — Form W-7 Step by Step

The ITIN application is submitted via IRS Form W-7 (Application for IRS Individual Taxpayer Identification Number). Here is the 2026 process:

Step 1 — Determine your reason for applying: Form W-7 requires you to select the exception category that applies to your situation. The most common for foreign LLC owners is Exception 1 (passive income) or the general filing requirement. Your CPA or Certifying Acceptance Agent (CAA) can confirm the correct category.

Step 2 — Complete Form W-7: Download it from irs.gov. You will need your full legal name, mailing address (your Doral virtual office address at Work Together Center is accepted for IRS correspondence), foreign address, date/country of birth, and the treaty claim or exception category.

Step 3 — Gather identity documents: The IRS accepts 13 types of documents. A valid foreign passport is the most common — it alone satisfies both identity and foreign status requirements. If you submit a passport, only one document is needed. Otherwise, you need one primary document plus one secondary document.

Step 4 — Submit through a CAA or by mail: A Certifying Acceptance Agent can certify your passport without you mailing the original. This is the safest option for foreign applicants. Alternatively, mail original documents with Form W-7 to the IRS ITIN Operations center in Austin, TX. Original documents are returned within 60 days.

ITIN Renewal: Does Your ITIN Expire?

Yes. ITINs that have not been used on a federal return for three consecutive years expire. Additionally, ITINs with certain middle digits (e.g., 70-88, 90-99) expire regardless of use. If your ITIN is expired or expiring, renew it before filing your next return to avoid processing delays and loss of certain credits. Use Form W-7 with "Renewal" checked.

Why Your Doral Business Address Matters for ITIN and Tax Filings

When the IRS issues your ITIN, they send the assignment letter to the address listed on Form W-7. Using a foreign address means the letter must cross international borders — delivery is unpredictable and can take 6-10 weeks. Using Work Together Center's Doral address (7500 NW 25th ST Suite 237, Doral FL 33122) as your US mailing address means the letter arrives in 1-2 weeks. We scan it the same day and send it to you digitally, wherever you are in the world.

Beyond the ITIN letter, your Doral address is the address used on all subsequent IRS correspondence: tax notices, refund checks, and audit letters. Having all that correspondence channeled through a professional address with reliable scanning and forwarding is a critical advantage for any foreign entrepreneur managing their US tax affairs remotely.

Traditional US address options: Using a personal US contact's address creates privacy and reliability risks. Using a PO box may not be accepted by the IRS for Form W-7. A virtual office address at Work Together Center — $49/month — is IRS-accepted, provides a professional Suite 237 address, and includes mail receipt, scanning, and digital forwarding as standard features.

Frequently Asked Questions

Who needs an ITIN as a foreign entrepreneur in the US?

Foreign entrepreneurs who do not qualify for a Social Security Number but have US tax filing obligations need an ITIN.

Can I use a virtual office address in Doral for my ITIN application?

Yes. Work Together Center's address (7500 NW 25th ST Suite 237, Doral FL 33122) is accepted by the IRS as a US mailing address on Form W-7. We receive, scan, and forward all IRS correspondence including your ITIN assignment letter. Plans start at $49/month.

How long does it take to get an ITIN in 2026?

The IRS typically processes ITIN applications in 7-11 weeks, up to 14 weeks during peak tax season. Applying through a Certifying Acceptance Agent (CAA) in Miami can accelerate the process since CAAs certify documents without requiring originals to be mailed to the IRS.
