Apply Through an IRS Certified Acceptance Agent
When permitted under strict IRS procedures, an authorized Certified Acceptance Agent may verify your qualifying identification documents.

However, documentation requirements are unique to each applicant's situation and tax status.

How the ITIN Application Process Works
Here's what we do:
If you cannot visit our office in Sunny Isles, Florida so we can verify your identifying documents, you can send the documents to us by mail or private carrier.
We will schedule a short video conference with you (or your dependents) to confirm your identity.
We will then immediately return your documents through your choice of delivery. This part, you need to pay for.
We will verify your documents showing proof of identity and foreign status, then properly prepare and sign Form W-7 and Form W-7 (COA). If we prepare your tax return or other qualifying document for IRS submission, we will send all documents by Priority Mail to the relevant IRS Service Center.
Here's the best part – we follow up with the IRS to ensure that the ITIN is issued. Unlimited follow-ups are included in the $225 flat fee.
Just submit the contact form, giving us your circumstances for needing an ITIN, and we will take it from there.
