West Sussex County Council’s Every Pound Counts survey will ask residents and businesses for their opinions on how public money is used.
Leader Louise Goldsmith said: “We’re working hard to provide better services for our residents while at the same time making £79million worth of savings.
“This inevitably means there will be changes to some of our services.
“The consultation is all about getting people involved in these issues and giving them a say on where taxpayers’ money should be spent and potentially where it could be saved.”
The online survey will include a budget setting section where people will have the chance to be “chancellor for the day” by allocating points – representing sums of money – to different areas.
Details of the survey can be found at libraries and Help Points or, by visiting www.westsussex.gov.uk/everypoundcounts
A paper copy can be requested by calling 01243 777100.
Information gathered during the consultation will be used to help form the budget for the next financial year (2012/13).
The consultation closes on Wednesday, October 19.
The results will be published in November.
