Though the mismatch is small around Rs 140 which I have paid it online through e-pay tax on portal and received the challan and an email communication from e-filling team mentioning that the payment is successful . Now what to do hereafter ?? or shall I be Ok with challan assuming everything done. Do I need to file revised ITR or file under rectification ?? Pl clear the confusion.......Regards DA

Greetings, Received Income tax Intimation u/s 143(1) with respect to the return of income filed by for the Assessment year 2022-23 regarding demand notice of payment for sec 234b There was no Advance tax paid for the mentioned period FY 2021-22, And the ITR was filed on 31-12-2023. As such for calculation of 234B, the number of months from Apr 1st 2022 was calculated as 21 and the amount to be paid on the Assessed tax 103600 was calculated as (103600*1%)*21 which was filed as 21,756 But the demand notice mentions the amount as 32,116 (which seems to be calculated as 31 months) Was my calculation of 234B considering 21 months (01-04-2022 -> 31-12-2023) correct, in which case should I ask for a rectification for reprocessing ? Pls Advice. Thanks Verky
