Simon Harris announces a new tax for derelict residential sites, with administration to be handled by the Revenue Commissioners. The announcement is made alongside updated estimates of the scale of the issue across Ireland. According to the latest figures cited by both outlets, there are about 19,438 residential derelict properties across the State at the end of 2025. Both sources describe the government’s move in the context of addressing dereliction, though they do not provide detailed information in the supplied excerpts on how the tax is calculated, its rates, exemptions, or enforcement timelines. The reporting also does not specify whether the measure is already legislated or is subject to further consultation or parliamentary steps. Overall, the consistent points across the sources are that the tax is aimed at derelict residential sites and that Revenue will administer it, with the number of such properties estimated at roughly 19,438 by the end of 2025.
