As per Section 288B of the income tax act, the total tax computed shall be rounded off to the nearest Rs 10. The rounding off of tax would be done on the total tax payable or refundable and not to various different sub-heads of taxes like income tax, education cess, surcharge etc.
Rounding off would be done in the same manner as above i.e. firstly paise would be ignored and thereafter if the last digit in the total figure is 5 or greater than 5, the total amount should be increased to the next higher amount which is a multiple of Rs. 10.
