(2) Where working tax credit is payable and the amount which is payable has been calculated by reference to the earnings of the absent parent and another person—

(a)if during the period which is used to calculate his earnings under paragraph 2 or, as the case may be, paragraph 5, the normal weekly earnings of that parent exceed those of the other person, the amount payable by way of working tax credit shall be treated as the income of that parent;

(b)if during that period the normal weekly earnings of that parent equal those of the other person, half of the amount payable by way of working tax credit shall be treated as the income of that parent; and

(c)if during that period the normal weekly earnings of that parent are less than those of that other person, the amount payable by way of working tax credit shall not be treated as the income of that parent.]
