Real property taxation presents an enormous potential for revenues at the local level. It is considered as a progressive form of taxation as owners of real properties tend to fall within the medium- to high-income brackets and because property taxes increase as the price of properties rises. However, in the Philippines, this significant potential for revenue remains untapped. This is primarily because of the lingering issues and problems in the real property valuation system. This policy brief investigates these issues and explores how the Real Property Valuation Reform Act (RPVARA) can address these challenges to maximize the revenue potential of real property taxation, thereby supporting local development and service delivery.
