3D Scanner Against Tax Fraud: The Inspectors New Eye

Published on May 15, 2026 | Translated from Spanish

3D technology provides tax inspectors with tools to verify the real dimensions of properties or industrial warehouses from their computers. A clear example: checking whether the built volume of a premises matches what was declared for the IBI (property tax), avoiding travel and error-prone manual measurements.

A tax inspector examines a 3D model of an industrial warehouse on a screen, comparing its real dimensions with tax data, while IBI and validation icons float next to the digital scanner.

Programs like Autodesk ReCap or Agisoft Metashape allow processing point clouds obtained with laser scanners or drones. The inspector can compare the resulting 3D model with registered cadastral plans. If the actual height of a warehouse exceeds what was declared, a possible concealment of cubic meters is detected, forming the basis for recalculating pending taxes.

The inspector no longer needs to climb onto the roof with binoculars. Now a drone with a 3D camera flies over the plot and generates a model where the clandestine pool appears as a huge blue hole in the garden. The taxpayer will explain it is an ornamental pond, but the volumetric measurement software has already calculated the liters of water and the consequent surcharge.
