Increasing demands on children's services and adult social care has left Cheshire East Council having to find £7.5m in savings to balance its books this year.
The local authority has been reviewing its budget for 2018-19 and currently has a £5.5m overspend in its People department.
That includes coping with a rise in the number of cared-for children from 484 in March, to 510 in August.
There's also a £2.1m overspend in adult social care, £1.1m in the Corporate department and £1m related to employer pension contributions.
However, the council says it believes it'll take enough "mitigating actions" to balance the budget by the end of March.
