As I advised the Deputy in response to his Question No. 74 of 26 November 2015, figures for the cost of mortgage interest relief in 2014 and 2015 are highly provisional.
The cost of relief for 2016 and 2017 will depend on a variety of factors, including the numbers of mortgages, the monetary amount of the qualifying loans taken out, the rate of relief applying to those qualifying loans, the year the qualifying loans were taken out and the extent to which the ceilings for relief are impacted by changes in interest rates. Taking these issues into consideration, my Department and Revenue will review forecasts for the following years after the end year 2015 receipts are finalised.
