Residential Zoned Land Tax (RZLT)

 The Residential Zoned Land Tax (RZLT) is a tax aimed at activating serviced and residentially zoned land for housing.
Local authorities are responsible for identifying the land that is subject to RZLT.

What is the Residential Zoned Land Tax?

The Residential Zoned Land Tax was introduced in the Finance Act 2021. The objective of the tax is to activate land that is serviced and zoned for residential use or mixed use, including residential use, in order to increase housing supply and to ensure regeneration of vacant and idle lands in urban areas. These areas have been identified within statutory land use plans as appropriate locations for housing and they have benefitted from investment in the key services to support the delivery of housing. 

  • Local authorities are responsible for identifying the land that is subject to Residential Zoned Land Tax.
  • Residential Zoned Land Tax is administered by Revenue.

Land Subject to RZLT

The process to identify and map land that is subject to RZLT is undertaken annually by local authorities.

The initial mapping process has involved local authorities publishing draft maps and allowing landowners, and others, to make submissions on these maps. Submissions by landowners could challenge the inclusion of their land on a map, the date on which land first met the relevant criteria, or they could seek to re-zone the land.

Submissions on the Annual Draft Map 2027 may be made no later than the 1st of April 2026, either in writing to :

  • Residential Zoned Land Tax, The Compliance and Land Activation Unit, Town Hall,Crowe Street, Dundalk, Co Louth A91 W20C.
  • Or via the Louth Public Consultation Portal at https://consult.louthcoco.ie

 

Submissions on the Annual Draft Map for 2027 should be made in one medium only regarding:

(I) either the inclusion in or exclusion from the final map of specific sites, or

(II) the date on which a site first satisfied the relevant criteria.

 

Submissions should include the following:

  • a name and address
  • the reasons for requesting the inclusion or exclusion of lands on the map
  • Where the submission is being made by a landowner submit a map of scale 1:1,000 (urban area) or 1:2,500 (rural area). The map should be clear enough to  identify the location/area of land  which are the subject of the submission.
  • The applicable Parcel ID

 

Any such written submissions received by 1 April 2026 other than such elements of a submission which may constitute personal data, shall be published on the website maintained by the local authority concerned not later than 11 April 2026.

 

Please note your submission must clearly identify the site and outline what change (i.e. exclusion of land on a local authority map, the date on which the site first met the criteria for inclusion on the map, or support for the proposed exclusion of land from the map) to the Residential Zoned Land Tax mapping you are seeking, as well as provide a justification for the change sought. The submission must state the criteria set out in Section 653B of the Taxes Consolidation Act 1997 on which you rely in your submission for the land being in or out of scope. After reviewing your submission, the local authority may request additional information, such as proof of ownership.  

 

The proposed inclusions and proposed exclusions on the annual draft map are subject to submissions received. Any landowner who supports the exclusion of their land should make a submission in support of such exclusion.

Third Party Submissions

If you are making a submission about land that you do not own then you are a third-party submitter. In your submission you should include:

  • Your name and address.
  • Information to identify the land - either a written description, an Eircode or a map with the area outlined. Where the local authority cannot identify the land, it may not be able to take the submission into account.
  • For land on the map, you may wish to bring to the local authority’s attention to matters that demonstrate that the land is not in scope for the tax, or that the date that the land was considered in-scope is not correct and should be changed. 
  • Reference to criteria in Section 653B of the Taxes Consolidation Act 1997 – any submission should reference these, along with evidence for consideration by the local authority to support any claims regarding the serviced nature of the land or any exclusions that should be applied. These criteria must also be referenced if the submission seeks to include additional land on the map.
  • The submission should set out any justification for inclusion or exclusion of land, with reference to the criteria in the legislation.

Please note that although they are included on these maps, residential properties are not subject to RZLT if they are subject to Local Property Tax. It is not necessary to make a rezoning request or submission to remove this type of residential property from the map. 

Land appearing on the annual draft maps, taking into consideration submissions, will be included on the annual final map of land in scope for the tax in the local authority area. This map will be published on 31 January 2026. This land may be subject to the tax in 2026, unless it is a residential property subject to Local Property Tax or qualifies for other exemptions, as provided for in the legislation.

Making a rezoning request on the final Map 2026

An additional provision was made in the Finance Act 2024, facilitating a further round of rezoning requests to remove land from liability to the tax.  Rezoning requests can only be made for land identified on the final annual map for 2025, published on 31 January 2026.  Rezoning requests for other land will not be considered.

 

Where lands are identified on the Final Map for 2026  , a landowner or a person acting on behalf of a landowner may make a submission to Louth County Council  in respect of such lands  requesting a variation of the zoning of that land. The relevant submission period is the 1st of February 2026- 1st of April 2026. Submission should include the following information;

  • name and address
  • evidence of ownership (land registry/folio details)
  • detailed reasons  for any rezoning request, which may include continuation of an ongoing economic activity.
  • a map to a scale of 1:1,000 (urban) or 1:2,500 (rural) clearly identifying the relevant plot of land.

 

The landowner should set out why the change in zoning is in the interest of the proper planning and sustainable development of the area, as well as any other circumstances, such as their desire to continue with an ongoing economic activity they wish to bring to the local authority’s attention. Any information to support the claims of ongoing economic use should be submitted as part of the rezoning request

Any such written rezoning requests received by 1 April 2026 other than such elements of a submission which may constitute personal data, shall be published on the website maintained by the local authority within the relevant statutory period.

(It is requested that you please include your  name and address on a separate page to the content of your submission in order to assist the Louth County Council in complying with the provisions of the Data Protection Act)

 

NB: A rezoning request acknowledgement letter containing details of the recent planning history of the land will be issued by 30 April 2026 from the local authority. This letter of acknowledgement can be used to support a claim to an exemption from the tax arising in respect of the land which is the subject of the request for 2025. This claim must be made in the 2026 annual residential zoned land tax return, which must be made to the Revenue Commissioners on or before 23 May 2026. Please see www.revenue.ie for further details.

Submissions shall be made by one medium only, either:

  1. i) via the online consultation portal https://consult.louthcoco.ie/, or
  2. ii) in writing to Residential Zoned Land Tax , the  Compliance and Land Activation Unit, Town   Hall, Crowe Street, Dundalk, Co. Louth A91 W20C
