Which of the following is NOT typically responsible for verifying tax identification information?

Employers typically have the responsibility of collecting and verifying tax identification information from their employees when they are hired. This includes ensuring that the information provided on forms, such as the W-4 and related documents, is accurate and matches with IRS records. While employers do play a role in collecting this information, the ultimate responsibility for verifying it against official records usually lies with individuals such as IRS officials or tax preparers.

In this context, IRS officials are directly tasked with maintaining and verifying tax records, tax preparers assist taxpayers and may verify the accuracy of provided information before filing, and employees are responsible for providing accurate information on forms. Therefore, employers are not the ones who independently verify the tax identification information; they are mainly responsible for gathering it.
