Request you to please help me structure my salary to save max tax legally

I am working in a IT Company and i am not able to understand the calculated tax deduction (total 100000 INR in this financial year)based on my salary. I also see my basic salary is very high with very little tax exempt components. I ask this to my HR but they are saying this is the best salary structure. What allowance/reimbursement can be added to save maximum tax legally. How to lower down taxable amount.
I already exhaust 80c.
I fully utilize home loan interest exemption
I utilize 10000 rupees health insurance.
Please find attached herewith my salary structure, and help me.
Appreciate your help.
Thanks

A reference to latest IT provisions will help you.

Thank you very much.
How much is house loan deduction?
>>Principanl (80 c)1,50000, interest (24 e) 200000(I have exhausted 80 c and 24 e both already)
Are you paying Rs30000 tax every month?
>> No (computed tax in this financial year is 100000(1 lacs) )
I doubt there are no reimbursement in my salary, that's why causing high tax calculation.

Is the house on rent or you are staying?
you can open PF or open PPF or ELSS upto 1.5 lakhs and start NPS a/c Rs50000 deduction is maximum authorised.
Salary will come down to 8L and then Housing deductions your salary can come down to 6L at least. and 20% bracket.
