It return file for new proprietory business

Dear All,

We just staterd our new proprietory business (Movers&Packers) on 31st Oct, 2011. Now its Dec'11. We have few doubts for IT return filling for our new proprietory business.

1. Do we need to file IT return now?

2. When we have to file IT return?

3. If we need to file IT return which form will be applicable for us?

4. We are thinking of buying a house after two years and as per GOV/Bank. rule, we need to submit last 2 years IT return for housing loan. We know we are thinking very long but its fact that if we want to buy a home after two years we have to star the preparation from now. So we want to know, can we file IT return for our proprietory business under Rs.9 lakh, can we do? Can we show income under 9 lakh and file IT return?

Please do revert. Thanks in advance.

Regards,

Pari, Bangalore
