What is the Mortgage Interest Tax Credit?

The Finance Act 2023 introduced the Mortgage Interest Tax Credit (MITC). This tax credit is for taxpayers who have made payments in respect of a qualifying loan for a principal private residence. The Mortgage Interest Tax Credit was originally only available for the year 2023 but was extended to include the years 2024, 2025 and 2026.

What documents do I need to apply?

To claim the credit, the following documents are required to be uploaded through Revenue’s online services :

• Confirmation of mortgage balance as of 31 December 2022
• 2022 Certificate of Mortgage Interest
• 2023, 2024 and 2025 Certificates of Mortgage Interest (depending on which years you are claiming the Mortgage Interest Tax Credit).

Customers received their 2022 Certificate of Mortgage Interest and Mortgage Statement in January 2023, their 2023 documents in January 2024 and their 2024 documents in January 2025.

2025 Certificates of Mortgage Interest and Mortgage Statements will be issued from January 2026.

You can request a duplicate Mortgage Statement and Certificate of Mortgage Interest by calling our Customer Service Team on 0818 251 008.
 

How do I apply for the Mortgage Interest Tax Credit?

In order to claim the Mortgage Interest Tax Credit for the 2023, 2024 or 2025 tax years, the individual must file an Income Tax Return via Revenue’s online services .

My mortgage loan transferred from Ulster Bank to AIB. How can I request the required documentation to claim this tax credit?

If you require a mortgage statement for any period up to 21st July 2023, you can request this from Ulster Bank by visiting their Mortgage Customer Support Hub. Alternatively, you can contact their Customer Service team on 0818 210 275, 09:00am to 17:00pm, Monday to Friday (excluding Bank Holidays).

Your Mortgage Statements and Certificates of Mortgage Interest for the period after you transferred to AIB have been issued to you, while your Mortgage Statement and Certificate of Mortgage Interest for 2025 will be issued to you in the coming weeks. You will need both Mortgage Statements and Certificates of Interest from the period your mortgage was with Ulster Bank (for 2022 and up to 21^st July 2023) and AIB (from July to December 2023) in order to claim the total interest tax relief available to you for the year 2023.

Am I entitled to claim this tax credit?

An individual will be entitled to claim the MITC for the 2023, 2024 and 2025 tax years where they:

• Paid interest on a qualifying loan in the years 2022,2023, 2024 or 2025
• The interest on the qualifying loan increased from 2022 to the relevant claim year (2023, 2024 or 2025).
• The outstanding mortgage balance on 31 December 2022 was between €80,000 and €500,000.
• The property (situated in the State) was his or her principal private residence or the principle private residence of a dependant relative.
• Local Property Tax obligations in respect of that property are satisfied.

The amount qualifying for relief at the standard rate of tax, 20%, is capped at €6,250 per property. This is equivalent to a maximum tax credit of €1,250.

I redeemed my mortgage in 2023, 2024 or 2025. Can I still claim this tax credit?

Yes, you will still be able to claim your tax credit. Where interest has been paid for less than a full year in 2023, 2024 or 2025, an adjustment is required so that your claim can be assessed on a pro rata basis.
