How much can you claim?

The Mortgage Interest Tax Credit reduces your Income Tax liability for the tax years 2023 and 2024.

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 per year from the Mortgage Interest Tax Credit is €1,250 per residence.
