(1B) For the purpose of paying tax under sub-section (1A), tax shall be determined at the average of income-tax computed on the basis of the rates in force for the financial year, on the income chargeable under the head "Salaries" including the income referred to in sub-section (1A), and the tax so payable shall be construed as if it were, a tax deductible at source, from the income under the head "Salaries" as per the provisions of sub-section (1), and shall be subject to the provisions of this Chapter.

(iii) from the date of the assessee ceasing to be the employee of the person,

whichever is the earliest, on the basis of rates in force for the financial year in which the said specified security or sweat equity share is allotted or transferred.]

(2)  Where, during the financial year, an assessee is employed simultaneously under more than one employer, or where he has held successively employment under more than one employer, he may furnish to the person responsible for making the payment referred to in sub-section (1) (being one of the said employers as the assessee may, having regard to the circumstances of his case, choose), such details of the income under the head "Salaries" due or received by him from the other employer or employers, the tax deducted at source therefrom and such other particulars, in such form and verified in such manner as may be prescribed, and thereupon the person responsible for making the payment referred to above shall take into account the details so furnished for the purposes of making the deduction under sub-section (1).

(2B) Where an assessee who receives any income chargeable under the head "Salaries" has, in addition, any income chargeable under any other head of income (not being a loss under any such head other than the loss under the head "Income from house property") for the same financial year, he may send to the person responsible for making the payment referred to in sub-section (1) the particulars of—

(a) such other income and of any tax deducted thereon under any other provision of this Chapter;

in such form and verified in such manner as may be prescribed, and thereupon the person responsible as aforesaid shall take—

(i) such other income and tax, if any, deducted thereon; and

(ii) the loss, if any, under the head "Income from house property",

also into account for the purposes of making the deduction under sub- section (1) :

Provided that this sub-section shall not in any case have the effect of reducing the tax deductible except where the loss under the head "Income from house property" has been taken into account, from income under the head "Salaries" below the amount that would be so deductible if the other income and the tax deducted thereon had not been taken into account.

(2C) A person responsible for paying any income chargeable under the head "Salaries" shall furnish to the person to whom such payment is made a statement giving correct and complete particulars of perquisites or profits in lieu of salary provided to him and the value thereof in such form and manner as may be prescribed.

(5)  Where any contribution made by an employer, including interest on such contributions, if any, in an approved superannuation fund is paid to the employee, tax on the amount so paid shall be deducted by the trustees of the fund to the extent provided in rule 6 of Part B of the Fourth Schedule.

(6)  For the purposes of deduction of tax on salary payable in foreign currency, the value in rupees of such salary shall be calculated at the prescribed rate of exchange.
