Subject to fund rules, an employee may authorise in writing a set amount to be paid from post-tax wages into the same fund receiving the employer's contributions, and may change the amount from the first of the month after giving 3 months' written notice. The employer must remit each authorised amount within 28 days after the close of the month in which it was deducted.
