How much can you claim?

Note

Changes to this information were announced by the Minister for Finance in his budget speech on 1 October 2024. For more information, please see Budget 2025.

The Mortgage Interest Tax Credit reduces your Income Tax liability for the tax year 2023.

You must have an Income Tax liability to offset against to benefit from the Mortgage Interest Tax Credit. The credit does not provide relief against Universal Social Charge (USC) or Pay Related Social Insurance (PRSI).

You will not be able to fully utilise the credit if the credit due exceeds your Income Tax liability. However, you can receive a partial refund. This refund will be equal to your total Income Tax liability for the year.

Tax relief is granted at 20%. The maximum amount you can be refunded from the Mortgage Interest Tax Credit is €1,250 per residence.  

Revenue systems will calculate the relief due to you when you have input the required information.
