Bank Locker Rent charges deductible against Fixed Deposits / SB interest?

Income and expenses can be setoff from the same source of business

As these charges are not incurred for earning bank interest, the same is not deductible

Exactly,

The interest is earned against SB/FD and expenses incurred to earn this income only admissible for set off against income.

Locker Rent is not an expense against earning income of the above, hence it is not allowed to claim as per Sec.57

If you link your locker, you can setoff with interest income

@ Yasaswi - the ET article mentions adjusting of locker rent against the interest on FD. It does not say that for tax computation such adjustment is possible. In fact, it clearly states that the assessee need to remember offering such FD interest income to tax since there is high likelihood as the rent is adjusted against the locker rent, no entry is passed. To reiterate, only those expenses which are incurred exclusively to earn interest income can be claimed as deduction. Since the locker rent is not incurred for earning FD interest, the same cannot be allowed as deduction against FD interest while computing tax

Dont worry, I only do reporting, cost and corporate financial management here and not taxation and auditing. I just involve myself once in a while.
