Invest money and save tax? how much possible?

Hello dear friends,

Kindly let me know what are the ways to save income tax if money is invested in different things?

Also what is maximum limit that one can save by investing etc.

I have heard that if invest in new business then it is exempt? Is it True?

Share markets? New business etc?

I do not want to give money to government because they spend money in corruption. I would rather invest in new business, or ventures. Even share market is fine..

Any information is highly appreciated!
