Total professional income during previous year is 56200 received as a legal retainer on which Tds was deducted at ten percent under section 194j showing it fees for professional services. Now the assesse is employed for one year on contract and according to contract the amount payable for full duration of contract will exceed 150000 as monthly payment is 13000 before Tds. But during last financial year 56200 was received from November to march. So is the assesse liable to maintain books of account as per requirements of section 44aa of income tax act?
