Verifying Taxpayer Identity

Entering Identification Data

Familiarize yourself with the Volunteer Resource Guide, Main Information Sheet section. Be sure to read all the details and helpful hints for entering the taxpayer's identification information.

When you enter a SSN in the tax software, the program will warn you if the number might be incorrect or invalid.

Tax Software Hint

The tax software transfers the information from the Main Information Sheet to the appropriate tax form.
