Transport Minister Leo Varadkar has said that those who break the law one day should not expect protection from it the next.
Minister Varadkar was commenting after calls from some unions for workers not to pay the €100 household charge.
There are just 11 days left to pay the charge, which comes with penalties if not paid before the registration deadline of March 31.
Minister Varadkar insisted there are no plans to extend the deadline despite calls from Fianna Fáil to do so, and he said householders have a responsibility to respect the law.
"People have the right to object to something if they don't agree with it," he said.
"But people also do have a responsibility to obey the law - and you can't break the law one day and then expect the law to be able to protect you the next day.
"You can't refuse to pay your taxes one day, and then expect to be able to draw on other people's taxes when you need to avail of services," he added.
