What to check

What to include in a case summary

Tell us your residence country, the reason you need an ITIN, whether a U.S. tax return is involved, and whether the applicant is you, a spouse or a dependent. State your preferred language for a written reply.

Send a brief first email, not identity scans

Describe the federal tax reason, country of residence and whether a U.S. return is expected. Do not send a passport scan, full tax return, complete taxpayer number or bank records in the first message.

IRS fees and private service fees

The IRS does not charge a fee to process Form W-7. Private preparers and acceptance agents may charge for their services; confirm the exact scope and price before engaging anyone.
