Revenue is extending the property tax deadline until close of business this Wednesday evening (April 2nd) due to the massive number of calls it has received.

Revenue officials say they lining-up a string of penalties for homeowners who fail to meet the property tax deadline

€6 million has been collected over the past 48 hours bringing the total compliance rate to 88%. Those who have not paid are being warned that they could be brought before the courts.

A last-minute scramble to pay the property tax is expected ahead of the deadline - now moved to Wednesday.

Interest will kick-in immediately once the deadline passes as the Revenue puts its compliance programme in action.

Officials say tougher penalties await those who continue to ignore the ultimatum - including deduction from wages, referral of the debt to a Sheriff or Solicitor and the prospect of being brought before the courts.

Over 2,000 homeowners have admitted undervaluing their properties 

Those who deliberately undervalue their home will also be under scrutiny. 2,000 have already owned up to under-declaring since November.

And there is also expected to be a surge in the number paying arrears on their 2012 household charge, with 2,000 payments made in the last couple of days.

Revenue say interest will be charged on outstanding local property taxes after today at the rate of 0.0219% per day from the date the tax was due.
