Wis. Stat. § 70.115: Taxation of real estate held by investment board.

All real estate owned or held by any of the funds invested by the investment board, other than the constitutional trust funds, shall be assessed and taxed in the same manner as privately owned real estate. Such taxes shall be paid out of the fund to which the lands belong or for whose benefit they are held. If such taxes are not paid, the real estate shall be subject to inclusion in a tax certificate under s. 74.57 as are privately owned lands.
