£5.2 million could be taken from the pension pot of public sector workers and transferred into government's revenue account.
It follows the increase of early retirement from a number of staff and others leaving the public sector with their pension entitlement.
Government budgeted for it to cost £26 million over the last financial year but the net expenditure on public sector pensions has actually reached £58.4 million.
In February Tynwald approved the transfer of £27 million from the Public Service Employee Pension Reserve to cover the cost.
The additional funds are set to rebalance the budget.
