48. Unless a pension plan or, in the case of an insured plan, an insurance contract sets a higher rate of interest, any contribution which has not been paid into the pension fund or to the insurer shall bear interest, from the last day of the month following the month for which it should have been paid or, as the case may be, the last day of the month following the month in which it was collected, at the rate prescribed by section 44 or 45 or, in the case of the employer contribution under a defined benefit plan or a target benefit plan, at the rate of return of the pension fund. However, in the case of a special payment, interest accrues from the day that follows the date on which it becomes payable.
