one of my client has this query...

he has an outstanding balance with one of his builders for 35L n he received payment for rs.5L from him in cash, stating that i cant give u a cheque now cuz dont have balance with me in my bank a/c at present but will give u a cheque later....

now my client says wht entry shud be passed in books, because as per income tax act, S.40A(3) as in excess of 20000 other than by way of a/c payee cheque or demand draft?
