Town halls have "a moral duty" to freeze council tax for families struggling with rising household budgets, the Government has said.
Communities and Local Government Secretary Eric Pickles warned English councils they risked voters' anger if councillors ignored ministers' offer of a one-off handout to cover shortfalls created by the proposed freeze.
His call came as it emerged 15 local authorities plan to defy the Government, despite voters grappling with a squeeze on finances amid rising unemployment.
Mr Pickles said: "Freezing council tax is practical help every councillor can offer their constituents.
"A vote against the council tax freeze is a vote for punishing tax-rises and Labour's opposition to the policy shows their contempt for hard-working households.
"Local taxpayers will remember that decision next time they cast their vote at the ballot box.
"Councillors have a moral duty to sign up to keep down the cost of living. Anything less is a kick in the teeth to hard-working, decent taxpayers."
Prime Minister David Cameron has pledged £1 billion to help English town halls freeze the levy, but councils claim they would still face a shortfall despite the extra money.
Local authorities can snub the offer but must hold a referendum if they want to hike council tax by more than 3.5%.
Whitehall figures show 142 English councils have so far agreed to freeze the levy, but others say raising council tax is the only way they can protect services with cuts in central government grants.
