Revenue has confirmed that approximately 1,800 Residential Zoned Land Tax (RZLT) returns have been filed so far, generating nearly €40 million in tax payments in the first year the charge has come into effect.
The RZLT applies to land that is zoned for residential use and is adequately serviced, as identified on maps published by Local Authorities. The measure is intended to encourage landowners to activate existing planning permissions or to seek planning permission for development-ready land, with the broader goal of increasing housing supply.
This year marks the first time a charge has been levied under the RZLT framework. Revenue reported a significant uptick in registrations and return filings in the days leading up to the original deadline. To facilitate compliance, the tax authority extended the 2025 filing deadline by one week to May 30.
Since the extension, site owners have continued to engage with the filing system, with Revenue welcoming the increased participation. However, officials reminded landowners that the RZLT is a self-assessed tax, meaning they are responsible for evaluating their liability and ensuring they meet payment and filing obligations.
“Site owners who believe they may be subject to RZLT should take all reasonable steps to determine their liability and act promptly,” Revenue said in a statement.
The authority also noted that those seeking exemptions or deferrals must still submit a return to claim these reliefs. Failure to file on time could result in surcharges ranging from 10% to 30% of the annual tax liability, depending on the length of the delay.
Revenue urged landowners to review the detailed guidance materials available on its website and to act quickly if they have yet to fulfil their obligations.
The introduction of RZLT forms part of the government’s broader strategy to tackle land hoarding and boost residential development, particularly in areas with high housing demand. By applying pressure on landowners to either develop or release land to the market, the tax is expected to play a key role in addressing Ireland’s housing crisis in the coming years.
