I am advised by Revenue that the 80% windfall tax relating to gains attributable to a rezoning of land does not apply to disposals on or after 1 January 2015. A rezoning means a change under the Planning and Development Act 2000 from non-development land use to development land use, that is, from agricultural and amenity uses to residential, commercial or industrial uses or a mixture of such uses. The tax applied to gains on the disposal of such land in the period commencing on 30 October 2009 and ending on 31 December 2014.
