Residential Zoned Land Tax

Residential Zoned Land Tax

Important note on The RZLT

Please note that although residential properties are included on the draft map, residential properties are not subject to the Residential Land Zoned Tax (RZLT) if they are subject to Local Property Tax. It is not necessary to make a submission to remove this type of residential property from the map.

Where residential properties are larger than 0.4047 (1 acre), they are similarly not subject to the RZLT but must register with the Revenue Commissioners.


The Government’s Housing For All – A New Housing Plan for Ireland proposed a new tax to activate vacant land for residential purposes as a part of the Pathway to Increasing New Housing Supply.

The Residential Zoned Land Tax (RZLT) was introduced in the Finance Act 2021. The process to identify land to which the tax applies is now underway and the tax will be payable from 2024.

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 locations. These locations have been identified within statutory land use plans as being appropriate locations for housing and they have benefitted from investment in the key services to support the delivery of housing. 

The RZLT process has two parts:

1) Identification and mapping of the land in scope for the tax. This is undertaken by local authorities through the publication of draft and supplemental maps – see below.

2) Administration of the tax, which is to be undertaken by the Revenue Commissioners from 2024 onwards. 

Identification of Land liable to RZLT

South Dublin County Council has prepared a draft map of the land considered to be in scope for the RZLT as of November 1, 2022.

The draft map is available to view here: Draft Map

and at the Planning Counter, South Dublin County Council, County Hall, Tallaght, Dublin 24, D24 A3XC (Mon-Fri (excluding Bank Holidays) between 10.00a.m. and 4.00p.m.)

How to make a submission

Any interested individuals or parties may make submissions in respect of land on the draft map in writing through the consultation portal up to the 1 January 2023.   


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

Submissions can be made by the public on the draft map from November 1, 2022, until January 1, 2023. These submissions can challenge the inclusion of particular lands on the draft map on the basis that those lands do not meet the criteria set out within the relevant legislation; the date on which the land is considered to meet this criteria; or can request a change of zoning. During the draft map stage, submissions can also identify additional land which appears to meet the criteria and so falls into scope, and which may be placed on the supplemental map.

A supplemental map will be published on 1 May 2023 identifying additional land considered to be in scope as a result of a change of zoning, servicing or where the local authority becomes aware of the fact that land, which didn’t appear on the draft map, may meet the criteria for being in scope, such as where this has been identified during submissions. The supplemental map will also be on public display and open to submissions which may challenge the inclusion of additional land on the map.

Land appearing on both the draft and supplemental maps, as amended to take into account the outcome of submissions made in respect of the land on these maps, will be included on the final map of land in scope for the tax in the local authority area to be published on 1 December 2023. This land will be subject to the tax unless it is exempt as a residential property, as outlined above.

The RZLT draft map as prepared and published by the local authorities includes lands that meet the relevant criteria for inclusion on the map as set out in the legislation.

The administration of the RZLT is a matter for the Revenue Commissioners.

The legislation underpinning the RZLT may be found at Part 22A of the Taxes Consolidation Act 1997. Guidance in respect of the administration of the tax may be found here

The Residential Zoned Land Tax Guidelines, as prepared and published by the Department of Housing, Local Government and Heritage, to aid planning authorities in publishing the maps can be viewed here.
