Residential Zoned Land Tax (RZLT) is a self-assessed annual tax which is calculated at 3% of the market value of land within its scope. It is charged on the 1 February each year beginning in 2025 and applies to land which is zoned for residential use and is serviced and identified on maps published by Local Authorities, but which is not a residential property. RZLT aims to prompt residential development by incentivising landowners to activate existing planning permissions, or to engage with planning authorities to seek planning permission in respect of relevant land.
The legislation underpinning RZLT requires local authorities to consider whether land satisfies the relevant criteria for the tax, being that the land in question is zoned for residential use, serviced and not otherwise excluded from the relevant criteria, and to prepare and publish maps identifying land within the scope of the tax. These maps are updated annually for any changes in the zoning and servicing status of the land which has already been included on such maps, to reflect any additional land which falls within the scope of the tax and to exclude any land that has fallen outside the scope of the tax.
Draft revised maps are published by local authorities by 1 February each year and owners of land appearing on draft revised maps are provided with an opportunity to make submissions regarding whether their land satisfies the relevant criteria and the date from which it satisfied the criteria. If a local authority determines that land subject to such a submission does satisfy the relevant criteria for inclusion on the draft revised map, the legislation affords the landowner an opportunity to appeal the local authority determination to An Coimisiún Pleanála.
The tax is charged in respect of land included on revised maps published by local authorities by 31 January in the year after the publication of the draft revised maps, which reflect the outcome of the submissions and appeals processes.
Information in respect of the amount of RZLT declared, the number of exemptions claimed, and the total hectares returned, including and excluding exempt land, is published within the October 2025 property taxes report available on the Revenue website.

The policy objective is to ensure that the land is activated in a timely manner. The most important metric for judging the success of this tax is the number of planning permission applications, and the number of activations of planning permissions. This is reflected in the high percentage of the liability which is deferred as it shows that land which meets the criteria for RZLT, is not being left idle and development is taking place.
I am satisfied that RZLT is achieving its objective of activating land for residential development purposes. However, as with all taxes, it is kept under regular review by officials in my Department and if I believe any further changes are necessary, I will consider them as part of the annual finance bill cycle.
