Introduction

TheStatistics on housing declared in Personal Income TaxIt is based on the section of Real estate of the annual declaration of the D-100 declaration form for Personal Income Tax submitted by all taxpayers in the Common Tax Regime Territory. 

The interest that the real estate sector has generated in recent years, as a result of the high concentration of rental demand for primary residences in large urban centers and the shortage of supply in some so-called "stressed" areas, is the reason why a snapshot of the residential real estate market belonging to individual owners is incorporated into regular statistical information.

To understand how the new information is incorporated into housing statistics, cadastral information is required, allowing for the exclusive selection of residential homes owned by individuals filing income tax returns, and the characteristics of the homes used to construct the two most relevant variables: the statistical value of the average monthly rental price and the gross rental profitability percentage (quotient between rental income proportional to the number of days the property has been rented and the reference value as a percentage).

The Real Estate section of the income tax return allows us to understand the different uses that owners give to their homes (main residence, rented residence (main residence and others), and available residence), as well as the declared income and the time computed for each of the uses. That is, there is information about the characteristics of the properties (to classify them as residential), and their uses (to differentiate properties intended for primary residence), both in the Land Registry and in the Personal Income Tax returns.
