Hi Pankaj,
Basically it happens that we forget to deduct tds on time and during finalisation of accounts or during audit we came to know that tds has not been deducted on some amount.
If you had made full payment in april ie rs 1,00,000/- than it is a case of tds not deducted or else if you had made payment in April of Rs 90,000/- than you can show that tds has been deducted in April.
Now different scenario
Suppose you had made payment of Rs 90,000/- in jan only than you could not show that TDS has been deducted late since while making payment you had deducted TDS.
So in your case you can show Tds deduction date as 31st march.
Hope so it solves all your query. And my name is Mitesh not mitlesh
