Amount paid. For purposes of section 83 and the regulations thereunder, the term amount paid refers to the value of any money or property paid for the transfer of property to which section 83 applies, and does not refer to any amount paid for the right to use such property or to receive the income therefrom. Such value does not include any stated or unstated interest payments. For rules regarding the calculation of the amount of unstated interest payments, see 1.483-1(c). When section 83 applies to the transfer of property pursuant to the exercise of an option, the term amount paid refers to any amount paid for the grant of the option plus any amount paid as the exercise price of the option. For rules regarding the forgiveness of indebtedness treated as an amount paid, see 1.83-4(c).
