Queries regarding income tax & investment declaration

Hi,

I wanted to declare investment in my current company, and related to that I had few queries, as mentioned below:

1. I have my annual CTC as 9 LPA, and the annual basic component is 3.3 LPA approximately. So, what would be my taxable income & take home income, annually and monthly ?

2. Based on my taxable income, how would be the tax % are calculated?

3. Out of my taxable income, how much would be tax free amount? And will that tax free amount limit can be stretched further by showing my PPF & HRA ?

Thanks, Avinash Kumar
