The NIC District Centre of Junagadh, Gujarat has developed a software package for calculation of Stamp Duty for the Collectorate. The function of the Stamp-Duty and Valuation office is to recover the remaining stamp duty from the Party who has purchased property in the form of land or building and has not paid the complete stamp duty. The software package acts as a ready reckoner for such cases. This system is based on the rates which are calculated according to the type of property and the present market rate. This helps to verify the stamp-duty already paid and recalculates the difference as per the prevailing market rate. The system is divided into three types of areas viz. Rural, City Survey and Town Planning Scheme. The rates are calculated for each survey number using specific formulas. An approximate data of 3 lakh survey numbers covering 1221 villages and 23 cities of Junagadh and Porbandar Districts have already been entered into the system with the complete description of the areas. Multiple copies of village wise listing called "Jantri" have been printed in the local language Gujarati.This "Jantri" consists of around 2000 pages for each copy. This ready reckoner system also has the capability of finding out missing and duplicate survey numbers of the village. The data in the "Jantri" can be easily updated with the required modification at any time. The software has helped to make the functioning of the District Stamp-Duty Office of Junagadh extremely efficient.
