Kindly Make things simple. There are too many factors to calculate tax. Makes things confusing.
1. Increase the limit to 10 lakhs. 2. Filing should not be compulsary for those who earn less than 10 lakhs per year. 3. There should not be any benefit on the basis of savings. (Those who could not save anything should not be treated as traitors).
Have only one tax system. Remove all taxes on commodities.
