My cousin received intimation u/s 143(1) dt. 26-9-2018 for A.y. 2017-18, showing tax payable Rs.25380 as he did not paid tax on epf withdrawn, while filing his tax return in march 2018. But he did not pay that amount yet. How can he pay the demand amount now? Whether he has to recalculate the amount because of delay in payment?
