Old valuations in collecting realty taxes

We agree with the observation of the Office of the Solicitor General that without Executive Order No. 73, the basis for collection of real property taxes win still be the 1978 revision of property values. Certainly, to continue collecting real property taxes based on valuations arrived at several years ago, in disregard of the increases in the value of real properties that have occurred since then, is not in consonance with a sound tax system. Fiscal adequacy, which is one of the characteristics of a sound tax system, requires that sources of revenues must be adequate to meet government expenditures and their variations. (G.R. No. 76778. June 6, 1990)
