§ 1449-bbbbbb. Imposition of tax. Notwithstanding any other provisions
of law to the contrary, the county of Madison, acting through its local
legislative body, is hereby authorized and empowered to adopt and amend
local laws imposing in such county a tax on each conveyance of real
property or interest therein when the consideration exceeds five hundred
dollars, at the rate of two dollars for each five hundred dollars or
fractional part thereof. Such local law may apply to any conveyance
occurring on or after the date designated by such legislative body, but
shall not apply to conveyances made on or after such date pursuant to
binding written contracts entered into prior to such date, provided that
the date of execution of such contract is confirmed by independent
evidence such as the recording of the contract, payment of a deposit or
other facts and circumstances as determined by the treasurer.
