Bengaluru put its whole property tax roll on a map in 2016, colour-coded by who had paid. It took door-to-door surveys and drones, years later, to turn the map into 688 crore rupees of flagged under-declaration.

Bengaluru put its property tax roll on a map. GEPTIS, opened in December 2016 with India's National Remote Sensing Centre, colour-codes every assessed property by payment status and has grown from 600,000 property IDs over 225 sq km to more than 2 million records over 800 sq km. Mapping alone did not widen the tax net: in 2021 local reporting noted the corporation had never met a property tax target, and a state finance commission review found fewer than half the city's properties assessed. Enforcement came later, and two audit rounds combining GPS door-to-door surveys with drone imagery flagged 688 crore rupees of under-declared tax across 23,600 properties by February 2026.

Live 📅 since 2016

📊 Impact

688 crore rupees of under-declared property tax flagged across 23,600 properties in two audit rounds to February 2026 — amounts detected, not amounts recovered.

🎓 Lesson

A map of who owes is not a collection. GEPTIS coloured every assessed property by payment status from December 2016, and years later the corporation had still never met a property tax target while a state finance commission review found fewer than half the city's properties assessed. The money only started moving when the map was paired with something that knocks on doors - GPS door-to-door surveys and drone imagery - and even then what the audits produce is tax flagged, not tax collected.

What the mapping says
The sequence is in the sources: the map from 2016, the unmet targets and the assessment gap still there in 2021, and the audits that produced a number only once survey teams and drones were added. The reports describe the result as detected evasion.
Caveat
The entry's own reading of the sequence across three sources; none of them draws the conclusion.
