Taxable values of estates and gifts are the fair market value. For some assets, such as widely traded stocks and bonds, the value may be determined by market listings. The value of other property may be determined by appraisals, which are subject to potential contest by the taxing authority. Special use valuation applies to farms and closely held businesses, subject to limited dollar amount and other conditions. Monetary assets, such as cash, mortgages, and notes, are valued at the face amount, unless another value is clearly established.
