Trending @HCL; Understanding my income tax filing

Hello Buddy's I am looking for help, I want to have some clarification about if I can claim any amount for income tax return and what is the best way to file income tax and how to show the maximum amount of investment etc. to exempt from taxable income.

Details about my salary.

80-85k in hand 26042 basic 13021 HRA Rest are different allowance

My investment

12500 - PPF/per month 20,000 - in two different equity mutual fund per month 10,000 - in one more mutual fund through my wife demat account (is it good or I should invest in my demat for claim). So total 42k per month investment 10,000 Rent /month

Living in non metro city for tax

My TDS deducted every month is in b/w 8-9k

Now I want to claim my income tax as much as i can...

Can anyone help me and let me know how I can pay less tax and which strategies should I follow.

Thanks.
