Confused About TDS on Fixed Deposits? Understanding Limits Even with Form 15G

Understanding TDS on Fixed Deposits

How is TDS calculated on a Fixed Deposit? I have a savings account with SBI that has FD accounts linked to it. Every year, there is some TDS deducted despite filling out a 15G form. Therefore, I want to know what the applicable limit for TDS is after submitting the 15G form.

I found the following quoted information on the SBI site:

"In case the amount of interest paid/payable exceeds the applicable limit for all accounts linked to a single CIF (even though operating at different branches), Form 15G is not applicable. Hence, please do not submit."

Final tax on estimated total income should be Nil. Only in such cases, Form 15G should be submitted. If the interest exceeds Rs. 250,000 per year, TDS will be deducted by the bank.
