Two-thirds of the rental values used to establish local taxes are taken into account for airports and for facilities designed to combat water and atmospheric pollution that are subject to exceptional depreciation under the articles 39 quinquies E and 39 quinquies F.
As from 1 January 1991, the rental values of installations intended to combat water and atmospheric pollution referred to in the first paragraph are taken into account at half their amount.
The rental values of equipment subject to the exceptional depreciation provided for in Article 39 AB or Article 39 quinquies DA are taken into account for half of their amount when this equipment was acquired or created from 1 January 1992.
For the installations referred to in the first paragraph and the equipment referred to in the third paragraph, acquired or created as from 1 January 2002, and which are eligible for one of the exceptional depreciation methods mentioned in the aforementioned paragraphs, the condition relating to the recording of this exceptional depreciation is removed for the application of this article.
Municipalities and their groupings with their own tax system may, by means of a general decision taken under the conditions provided for in article 1639 A bis, increase to 100% the reduction in the rental value of installations designed to combat water and air pollution as defined in the first paragraph that were completed on or after 1 January 1992, as well as that of the equipment referred to in the third paragraph. Companies may only benefit from this provision on condition that they declare each year, to the tax department, the tax items falling within the scope of the 100% reduction.
