The transferal of taxing power and the discretion given to the local government in determining the Land and Building Tax Imposition Base (NJOP) has given rise to problems with investments in infrastructure development, especially in investments in toll roads. Such roads pass through more than one regency/municipality; therefore, business actors must deal with different regulations for Land and Building Taxes of Rural and Urban Areas (LBTRUAs). Through data-collection techniques, literature and documentation review, and in-depth interviews, this study shows that toll-road investments are high risk. They are objects for LBTRUAs and have a mobile tax base. The appraisal and provision stages of NJOP are crucial, because they determine the amount of LBTRUAs, which results in costs for toll-road business agencies. In general, the findings from the field show that since the devolution, the amount of LBTRUAs has tended to rise. As a tax levied within the official assessment system, the harmonization of the tax base and tax rate on toll roads as objects of LBTRUAs is necessary to create certainty and a business climate that is conducive to investment.
