Form W-7
Completed application with correct reason code selecting why an ITIN is needed and matching the taxpayer’s identity as shown on supporting documents.
An ITIN lets eligible individuals meet U.S. tax filing obligations, claim treaty benefits, and prevent improper backup withholding. Completing Form W-7 correctly avoids processing delays and ensures tax returns are accepted and refunds issued where applicable.
Tax professionals, IRS Acceptance Agents, or authorized family members often help assemble supporting documents and submit the application to reduce errors and processing time.
