Advance tax on interest income

Hello,

I have a question with regard to TDS.

A person's Income is as follws:

Salary: Rs. 600000 P.A.

Tds is regularly deducted from that.

Now this person wants to invest Rs. 100,00,000 in bank F.D. which will meture after 5 years. Interest income is Rs. 10,00,000 P.A.  which will be added to F.D. amount as and when accrued. and after 5 years he will receive total sum with interest. bank will deduct Tds on that @ 10% as and when it credits interest.

He wants to avoid the Advance Tax since he has little sum every year as salary for his needs.

Can he pay the tax on FD int at the time of meturity only by selecting the cash basis of accounting.???

And can he claim TDS on interest against his tax on Salary income since after 2 years he can not claim earler year's TDS???

OR If you can suggest some other way in the situation.
