Revenue Sheriffs have been called in 500 times this year to help collect unpaid property tax, it has emerged.
Revenue is advising homeowners that tomorrow is the deadline to register for the phased payment of the Local Property Tax.
Anyone who paid their LPT for 2014 in one lump sum or made regular payments by cash will also need to confirm their payment method for 2015.
Compliance rates for the tax are now at 94%.
Revenue spokesperson Vivienne Dempsey says anyone who is still refusing to pay will face additional costs.
"We have referred over 500 cases at this stage, up to October, to the Sheriff," she said.
"And invariably, once we've referred the case to the Sheriff, we find that the property owners are contacting Revenue at that stage, and are engaging with us to either pay in full, or enter into an agreement, but the difficulty there is that they have also incurred Sheriff's costs, so really we're encouraging all property owners to engage with us in advance of being referred to the Sheriff."
