I want to fund raise to start a business, do I need to pay tax or it can be considered investment?

Hi everyone, 

I am trying to raise funds from public: crowd funding, a very small amount of money like 100-500 from so many people and collect 1 cr to 2cr as funds to start a Business. 

I have referred razorpay website, it's mentioned if I am not a charity, I need to pay Income tax. 

But it's not my income, I am going to register a company and put this as capital investment. 

Please let me know if I can register Business after raising funds and put this all funds as investment, or should I register MSME without GST and raise funds and convert MSME unregistered business to PVT LTD company with GST? 

Help me to better make use of funds raised.
