To get a duplicate land tax receipt in Kerala, you can try online first (if applicable). Visit the Kerala Revenue Department website and check if your local body uses KSMART or Sanchaya portals. Look for "Duplicate Land Tax Receipt" or "e-Services'' options on KSMART, or search using land details on Sanchaya's "Quick Pay" section. If online options are unavailable, visit your local Taluk or Village Office in person with a valid ID and any details of the original receipt. There might be a small fee for obtaining a duplicate. It's always best to contact your local office for the latest information on the process.
