Current position

The taxable event for ICIO requires being subject to a permit, responsible declaration, or prior communication according to the applicable regulations. Elements constructed by third parties outside of the work, such as machinery or installations, are excluded from the tax base, except for their installation cost. To be included, an element must be inseparable from the work, appear in the project, lack its own identity, and be necessary for habitability or use.

The DGT's position remains stable regarding the determination of the tax base, reiterating the exclusion of elements constructed outside the work that are not inseparable. Regarding the taxable event, it is confirmed that the absence of administrative control (permit or declaration) due to sectoral regulations exempts the tax obligation.

Turning points

  1. V0944-22

    Specifies that being subject to ICIO depends on the state, regional, or sectoral regulations that determine the requirement for administrative control.

  2. V2829-23

    Clarifies that if National Defense regulations exempt from municipal permits or preventive control acts, no ICIO taxable event exists.
