The Local Government (Household Charge) Act 2011 and the Local Government (Household Charge) Regulations 2012 provide the legislative basis for the household charge.
The household charge is on a self-assessment basis and it is a matter for an owner of a residential property on the liability date of 1 January, 2012 to determine if he/she has a liability and, if so, that person is required to declare that liability and to pay the household charge by 31 March, 2012.
I understand, from data provided by the Local Government Management Agency (LGMA), that as of 13 March, 2012, a total of 229,650 properties have been registered for payment of the household charge. This equates to some €23 million. The LGMA does not have the sub-national details of the registrations sought in the question.
