Lands and properties are considered as important entities for any Government. The property takes a center-stage for governance as well as revenue generation. Hence knowledge of the spatial distribution of businesses, properties, and their tax compliance status can be crucial in improving tax assessment and efficient collection of taxes.
GIS systems have turned out to be very effective to calculate and understand the tax assessments. Satellite/aerial maps along with manual surveys can be used to calculate the area of properties, and also additional information on the tax compliance status can be attached to the database.
GIS requires a simplistic approach:
Know Your Data —> Gather Your Data —> Analyse it in GIS Software
The property tax assessment may rely on different parameters depending on states. Here are the most common parameters which play a crucial role in the property tax assessment. One requires to determine the geographical location of properties and their following attributes :
Now, since we have understood the important parameters, the next phase is how do we gather this data? There is a lack of reliable data on informal sector participation in tax compliance, so some level of innovation is necessary to improve their prospect of participation. With the help of friends and acquaintances, property owners can be encouraged to provide accurate data and strong confidentiality parameters must be established.
For determining the geographical location of properties and their attribute data following steps may be followed:
Now, the important part is to compile all the information to generate insights and tax assessments. To start with, upload satellite/drone imagery which will serve as a base map. GPS coordinates of properties and businesses are prepared in an excel format and uploaded into the GIS Software environment where the coordinates are converted to point and polygon features, displayed and overlaid on the satellite or drone image.
Here shown is a base map(spatial data) captured using drones or satellites used for assessment of tax.
In the next step, an attribute table prepared is attached as the non-spatial data or attribute data in the Indshine GIS Software in an organized form to create a database.
Here's an excel file collected from the manual survey.
Here shown an excel sheet(non-spatial data) used for Tax Assessment.
After entering the attribute data into the GIS Software Environment, the spatial and the non-spatial data are linked to from the expected database aiding the database query aimed towards determining the owner of the property, type of property, the location, the unit area of the property, age factor, use factor, etc. using the toggles built-in Indshine GIS Software for quick hunting.
Here attached a sample project for reference.
In analyzing the data, descriptive statistical tools such as bar graphs and pie charts are used. Also, these visualizations and GIS maps developed on Indshine can be easily conveyed to decision-makers in a real-time and secured environment.
