Tax Reporting, Cost Basis, and Withholding

Quick Answer

Tax forms support tax reporting, and cost basis is information used in that reporting. Tax withholding requires a separate classification: some withholding is optional when it may be elected, while other withholding is required when applicable. Read the facts closely to determine whether withholding is elective or mandatory.

Tax-related questions test the purpose of the information and whether the customer has a choice about withholding.


Tax Forms and Cost Basis

  • Tax forms serve a tax-reporting purpose.
  • Cost basis has a role in tax reporting.
  • When these concepts appear together, distinguish the form used for reporting from the information used in that reporting.

Think of it this way: Tax reporting is the file, tax forms are part of the reporting paperwork, and cost basis is information the reporting process uses.
