Residents in the Weshpool area will face a 4.5 per cent increase in council tax, if proposals are approved later this month.
It will mean a rise of about £49.05 for an average Band D property in Powys, with the police precept and town and community council increases yet to be added.
Despite the proposed increase, there will still need to be £9.636m cuts and the portfolio holder for finance Councillor Wynne Jones warned worse could still be yet to come.
He said Powys County Council had received a slightly improved budget from the Welsh Government this year, although they were still one of the lowest funded in Wales, but he said the extra money had come with a dire warning from Minister Mark Drakeford for some more tough budgets to come.
Councillor Jones said Powys County Council is estimating an increase in council tax for 2018/2019 of 3.75 per cent and 3.75 per cent for 2019/2020.
The full council will make the final decision on the level of council tax at a meeting at County Hall on February 23.
