If a taxpayer cannot obtain a valid Social Security number, can you use their driver's license or passport instead?

In the context of tax filing and identification, a valid Social Security number (SSN) is essential for individuals to be properly identified by the IRS. If a taxpayer does not have a valid SSN, they cannot substitute other forms of identification, such as a driver's license or passport, in place of it when filing taxes. This is because the IRS specifically requires the SSN to process tax returns and ensure compliance with tax laws. Therefore, without a valid SSN, the filing process cannot proceed correctly, and alternatives like a driver's license or passport do not meet the necessary requirements set by the IRS. This reinforces the importance of obtaining the appropriate documentation for tax purposes and adherence to IRS regulations.
