Interest on Post office savings A/c

EXEMPTION OF 5,000 /- ONLY 

What about the deduction of 80TTA?

EXEMPTION
section 10(15)(i)
interest on POST OFFICE SAVINGS bank account is exempted - actual OR
1. RS 3,500 in case of an individual account
2. RS 7,000 in case of a joint account
which ever is lower
IN ADDITION TO THE ABOVE

DEDUCTION
section 80TTA deduction in respect of interest on deposits in SAVINGS ACCOUNTS (not being time deposit)
RS 10,000 or actual interest, which ever is lower is allowed as deduction

in your eg.
in case of individual account
taxable interest is 20,000 - 3,500 -10,000 =6,500
joint account
taxable interest is 20,000-7,000- 10,000 = 3,000

Thanks alot! 😊
