Fiscalidad

Spain faces a structural housing shortfall estimated at around 700,000 units, with social
housing accounting for just 3.3% of the residential stock, well below the EU average.
The EU’ s reclassification of affordable housing as a service of general economic
interest opens a legally secure path for combining public and private financing, but only if authorities rigorously model funding gaps and design compensation that is sufficient without generating windfall returns.

A static simulation applying 2040 demographic projections to 2025 household tax data estimates that population ageing alone would reduce Spanish tax revenue by around 3.3% through its impact on personal income tax, social security contributions, and VAT. The decline reflects the shrinking weight of younger and prime working-age households in the population, while immigration can only partially offset the shortfall and depends heavily on household composition and income levels.
