How It Works
Watch a full ITIN application from start to finish
- Step 1: Check Eligibility with AI. Answer a few questions and our AI determines your ITIN eligibility, the right reason code, and which documents you need.
- Step 2: Upload Documents. The IRS requires proof of identity and foreign status. Upload them securely to us through our guided process.
- Step 3: CAA Identity Verification. We authenticate your supporting documents and perform the IRS-required identification verification — in person or by video from anywhere.
- Step 4: Print & Sign Documents. Review your completed W‑7 application package, print the forms, and sign where required.
- Step 5: Mail to Our Office. Mail your originally signed document and passport to our office. We return originals via tracked courier once ID verification is complete.
- Step 6: Receive ITIN Number. As your CAA, we get a copy of your ITIN approval notice faster and will send you your ITIN number right away — no waiting for regular mail.
Why a Certifying Acceptance Agent matters
The same application, handled two very different ways
Filing on your own
- Mail your original passport to the IRS and wait for its return
- Mistakes surface only after the IRS rejects the application
- Start over the ITIN Application process if the Form W-7 gets denied
With a Certifying Acceptance Agent
- Keep your passport safe — certified copies of documents are mailed
- The W-7 is prepared and certified by a CAA before it is submitted
- Submitted through a formal agreement with the IRS ITIN Policy Section
MiklosCPA Inc. is an IRS-authorized Certifying Acceptance Agent.

Who We Help
Common situations where you need an ITIN
Spouses & Dependents
Your spouse or family member is listed on a U.S. tax return to claim a tax benefit, but they do not have a Social Security Number.
Non-Residents
You live outside the U.S. and need to file a U.S. tax return or claim a refund, but you do not qualify for a Social Security Number.
Tax Matters
You have a U.S. tax obligation (such as a tax refund, a tax treaty benefit, or investment income) and need a tax ID to file or reduce your taxes.
Students, Researchers & Work Authorized
You are a foreign student, teacher, researcher, or hold a work visa in the U.S. and need to file a tax return, but do not qualify for an SSN.
Estates
A family member has passed away and a U.S. tax return needs to be filed on their behalf. An ITIN is needed for the deceased person.
Special Tax Situations
In some situations, the IRS allows you to apply for an ITIN without a full tax return, such as for bank interest, real estate transactions, or partnership income.
If you are a U.S. citizen or lawful permanent resident, you do not need an ITIN. Apply for a Social Security Number instead.
Choose Your Plan
Simple, transparent pricing for your USA ITIN application
*Once information for application is provided to CAA with required supporting documents. The IRS advises allowing about 7 weeks for a status notice (or 9–11 weeks during peak season/overseas submission) when not done by a CAA.
