Council tax bills in England are set to rise by about 4% on average this year, the BBC has learned.
A Local Government Association study of 100 draft council budgets suggests some councils may put bills up by nearly 5%.
The projected charge for an average Band D property for 2007-8 will be £1,373, the research suggests.
The Association has warned that many local authorities will still have to ration or cut services despite the increases in tax.
Ministers say there is "no excuse" for large increases and have threatened to use capping powers.
If increases were to continue at such a rate, householders would be paying out £1,500 a year on average by 2011.
