Taoiseach confident people will pay household charge - The Irish Times - Wed, Mar 28, 2012
Looks like the people registering are also paying.
"Official figures from the Department of the Environment show 426,599 households were registered as at 4pm. There are also about 55,000 postal applications awaiting processing which are not included in that figure.
Total revenue generated from the householders who have paid to date is €42.7 million."
