This consultation page forms part of the public consultation on the Residential Zoned Land Tax on the Supplemental Map stage of the process, as per Section 653F of the Finance Act 2021. 

Housing Policy Objective 15.2 of 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 was introduced by the Finance Act 2021 and will come into effect from 2024, managed by the Revenue Commissioners. 

The objective of the tax is to activate zoned and serviced residential development land and land zoned for mixed use, including residential, for development 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.  

Please note that whilst residential properties are included on the Supplemental Map, they are not liable for the tax under Section 653O of the Finance Act 2021. A ‘residential property’ means any building which is in use as, or is suitable for use as, a dwelling. Owners of such properties will not be liable for the tax.  

Dún Laoghaire-Rathdown County Council hereby invites any interested individuals or parties to make submissions in respect of the Supplemental Map. The public consultation on the Draft Map takes place from Monday 1st May 2023 to Wednesday 1st June 2023.
