Dear, Rs.15,000/- is deduction u/s-57(iia) & not a tax rebate. Please refer the following:
Calaculation of Total Income of Mrs. X for the A.Y. 2015-16
Income u/h Salaries
Pension = 3,30,000
Income from other Sources
Family Pension = 2,70,000
Less: Deduction u/s-57(iia) = 15,000 = 2,55,000
(1/3 rd or pension or Rs.15,000, whichever
is less)
Interest Income on FD = 2,00,000 = 4,55,000
Gross Total Income = 7,85,000
Less: Deductions u/s-80C to 80U = Nil
Total Income = 7,85,000
Calculation of Tax Payable
Upto Rs.3,00,000/- = Nil
Rs.3,00,001/- to Rs.5,00,000/- = 20,000/- (10% of Rs.2,00,000/-)
Rs.5,00,001/- to Rs.7,85,000/- = 57,000/- (20% of Rs.2,85,000/-)
Total Tax Payable = 77,000/-
Add: Education Cess @ 3% = 2,310/-
Net Tax Liability = 79,310/-
Less: TDS = Nil
Self Assessment Tax = 79,310/-
(u/s-140A)
Notes:
(1) Service pension received is assumed to be the uncommuted pension.
(2) It is assumed that no TDS u/s-194A has been deducted on interest on FD amounting to Rs.2,00,000/- due to submission of Form 15H.
(3) Assessment Year assumed as 2015-16.
(4) It is assumed that the assessee is a resident senior citizen, hence there will be no liability on account of advance tax as the assessee doesn't have any income u/-h "PGBP".
(5) It is assumed that the assessee has paid the self assessment tax within due date, else interest u/s-234A @ 1% p.m. from the date after due date as per sec-139(1) to the date of furnishing of return or date of regular assessment u/s-144, whichever is earlier, will also be chargeable.
Hope your doubt is cleared now.
