A council has claimed that a single authority should replace the current six councils in Suffolk.
The current two-tier structure is set to be scrapped by the government, with a decision over the future make-up expected to be announced early in 2026.
Suffolk County Council said it believed its plans could save £39.4m a year. An opposing bid has called for three councils to oversee Suffolk.
A deadline to submit plans to the government is set for 26 September, followed by a public consultation from November until February.
Suffolk County Council's plan includes a levelling of council tax across the county.
In the current format people pay a varying amount, depending on which borough or district council they are served by.
It would see the current lowest rate, which is in Mid Suffolk, paid by everyone; the current figure is £2,114 for a band D property.
The savings claimed in the plan would see £78.5m over the first five years of the council coming into operation, which would be 2028.
After the first five years, annual savings of £39.4m in comparison to the current cost of local government are claimed.
The majority of the savings would come from staff cuts and renegotiating contracts, said Suffolk County Council.
Forecast redundancy costs could reach £13.3m.
Other pledges include:
- A £40m capital investment fund for towns
- A review of parking charges
- More powers for town and parish councils
- A unified planning framework across Suffolk
Richard Rout, Suffolk County Council's cabinet member for local government reform said: "We are very clear that this would be a brand-new council with a new culture and a new relationship with residents, businesses, community and voluntary organisations and town and parish councils.
"Too often our existing councils, both county and district or borough, start from a position of no. We've heard this loud and clear and have built the One Suffolk proposal around enabling what people want to see locally and giving them access to their local council."
A joint bid, organised by the district and borough councils in Suffolk would see the county split into three unitary authorities.
The proposals would see new authorities based around the largest towns in Ipswich, Bury St Edmunds and Lowestoft.
A joint quote from the Suffolk district and borough leaders said: "People across Suffolk are proud of where they live, and they want decisions made by those who understand their communities.
"The three councils for Suffolk proposal delivers just that. It offers a balance between strong councillors' leadership and genuine local delivery, ensuring that our towns, villages, urban centres and coastlines and the communities and businesses within these areas all get the attention they deserve."
Suffolk County Council elections were postponed in 2025 as discussions were under way about the future of the council structure. It was not known yet if they would be held in 2026.
