Campaigners from the Taxpayers' Alliance have emphasised the need for councillors, who decide what the council tax should be each year, to practice what they preach.
"The problem is that councillors are not like anyone else when it comes to council matters," said a Taxpayers' Alliance spokesman.
He added: "They have been elected specifically to ensure the machinery of local government is run efficiently and effectively — and that includes paying their own council tax on time.
"Ordinary residents who pay up on time are entitled to know which of their councillors aren't doing the same.
"Councillors must pay on time to set a good example and to ensure that essential services are properly funded."
