I am advised by Revenue that Section 20 of the Finance (Local Property Tax) Act 2012 (as amended) allows local authorities to vary the basic LPT rate for residential properties situated within their respective residential areas. The LPT rate can be increased or decreased by up to 15% from the base rate.
With regard to the specific case to which the Deputy refers, Limerick County Council reduced the rate of LPT by 3% for 2015, but opted not to reduce the rate for 2016. I am advised that a member of the LPT team has already made direct contact with the person in question and clarified the reason for the increase in 2016 over 2015.
