Applying for or renewing an Individual Taxpayer Identification Number (ITIN) can be confusing—especially when documents, identity requirements, and IRS rules are involved. We help individuals and families understand the process, prepare the required forms, and avoid common mistakes that may delay processing.

An ITIN may be needed by individuals who have a U.S. tax filing or reporting requirement but are not eligible for a Social Security number, including certain spouses, dependents, and nonresident or resident aliens.
