          description: The Cost Basis refers to the total cumulative amount of after-tax
            premiums paid into a life insurance policy or annuity contract. It
            represents the non-taxable portion of withdrawals, policy loans, or
            surrenders, ensuring that policyholders are only taxed on gains
            above this amount
          example: 198

            value of a life insurance policy or annuity contract is calculated.
            The cost basis represents the total amount of after-tax money

            Act (TEFRA) of 1982 took effect. This distinction is important
            because TEFRA introduced new tax regulations on insurance products,
            including how withdrawals, policy loans, and annuities are taxed
