Mortgage Interest Tax Credit

Interest paid for less than a full year


If you drew down your mortgage in 2022 and were registered for Local Property Tax in 2023, you may be unable to claim the Mortgage Interest Tax Credit. This is due to a Revenue system error. A fix is currently scheduled to go live on 7 September 2024. We apologise for any inconvenience caused and thank you for your patience.

If you paid interest for less than a full year in 2022 or 2023, the relief due will be prorated. This means that the maximum relievable interest of €6,250, and the maximum tax credit of €1,250, will be adjusted to reflect the shorter timeframe. 

Revenue systems will calculate the relief due to you when you have provided the relevant information.

For the formulas used to adjust the relievable interest, please see Appendix 2 of Tax and Duty Manual part 15-01-11B
