In economics and financial operations, the tax value of a property is considered to be that which results from the relationship between various variables and which is closely linked to the property or building tax in a given municipal or state context. It is worth starting by defining what is understood by property. As opposed to movable property, real estate is those that cannot be moved without damage to them, insofar as their mobility is reduced as part of a land of which they are part. Among these, houses, buildings, dwellings of all kinds, farms, ranches or similar are considered and, in some cases, ships and aircraft in particular. In this sense, the fiscal value of each property is understood as the economic value, which is assigned to it by a state agency through various valuations and indices. In each context this may occur differently, but there is usually a shared methodology that facilitates tax valuation on a massive scale. The assignment of fiscal value is intended to constitute a reference base for the payment of taxes on real estate properties and, in turn, can be used in research on the real estate composition of a particular territory. Often times, the methodology that determines the tax value of homes and buildings is calculated on the basis of the value of the land and the value of the property in question. The built-up land can also be valued in this way, such as a vacant lot, and here the consideration will be given by the area covered, the basic unit value and other indicators of the situation. 
The tax or cadastral value of a property is the value assigned to it from the property tax and is calculated taking into account the value of the land, the construction and the rate of use in the relationship between the two.
