Dumfries and Galloway Council is being advised to prepare to cut more than £50m from its spending over the next three years.
A report for the local authority advises a savings target of more than £20m for the next financial year alone.
The figures could change later this year when the Scottish government finance settlement is announced.
The UK government recently unveiled plans to cut £6bn from public spending to tackle national debt.
Last month, the south west Scotland council dropped proposals to find an extra £3m of savings this year in anticipation of further reductions to come.
However, a report to the council has now recommended it sets a series of targets to decrease its spending.
It would see £51.4m cut from its budget by the year 2014.
That is an increase of more than £12m on a previous estimate given to the authority in March.
Dumfries and Galloway Council will meet to discuss the proposals later this week.
