about the service

An ITIN is for an individual who needs a U.S. taxpayer identification number for a federal tax purpose but does not have and is not eligible for an SSN. Non-U.S. residency, an LLC or a platform account alone does not establish eligibility. A tax return is generally required unless an IRS exception applies.
In most cases, yes. An ITIN is usually submitted together with a U.S. tax return, unless you qualify for a specific IRS exception. We assess your situation first, then decide how to file.
Yes. Non-U.S. residents can apply using an overseas address — a U.S. address is not required.
If the ITIN application is not approved, all amounts paid are refunded less postage actually incurred. Refunds are processed within 30 calendar days from the date the unsuccessful application and refund amount are confirmed. Note that approval is ultimately decided by the IRS — we provide a genuine, compliant service and never promise "inside channels."
Allow time for the questionnaire and documents, W-7 review and your signature, the CAA interview and document checks, delivery, and IRS processing. IRS status notification usually takes about 7 weeks, or 9–11 weeks during tax season or for overseas applications. Preparation, delivery and additional-document requests can add time. Expedited service concerns internal handling, not guaranteed faster IRS approval.
First confirm whether you have an IRS-accepted U.S. tax purpose, then prepare Form W-7, your passport, and a U.S. tax return or exception documents. Through an IRS-authorized CAA, applicants in China can usually complete identity-document review under CAA rules and reduce the need to mail an original passport directly to the IRS. Read the China ITIN application guide.
