Mortgage Interest Tax Credit

Qualifying conditions

Note

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.

The Mortgage Interest Tax Credit is available to individuals who:

  • had a qualifying loan in the years 2022 and 2023
  • had the interest on the qualifying loan increased from 2022 to 2023
  • and
  • on 31 December 2022, had an outstanding loan balance of between €80,000 and €500,000.

You can only apply for the Mortgage Interest Tax Credit if the property was:

  • your principal private residence for 2023
  • the principal private residence of a dependent relative
  • or
  • the residence of a spouse which they used to attend their employment.

You cannot claim the Mortgage Interest Relief Tax Credit if the property is not a qualifying property.

Your property does not qualify for the credit if it is:

  • a residential property not compliant with Local Property Tax (LPT) obligations
  • a residential property not compliant with planning permissions
  • or
  • a residential property acquired from a connected party, where the purchase price substantially exceeded the property value.
