Last checked October 2026
What it is
A temporary tax credit for homeowners whose mortgage interest rose since 2022. For 2025 it is 20% of the increase in interest over 2022, up to €1,250. For 2026 only half the increase counts, so it is 20% of half the increase, up to €625. Your mortgage balance must have been between €80,000 and €500,000 at the end of 2022.
Who can get it
- The mortgage is on your main home (principal private residence) in 2022 and in the year you claim. Some other homes can also qualify. These include the home of a dependent relative (provided rent-free and you must be able to claim the dependent relative credit for them), the home of a former or separated spouse or civil partner and a home you or your spouse or civil partner use to attend work. Check Revenue's qualifying conditions page for the detail
- Your loan balance on 31 December 2022 was between €80,000 and €500,000
- The interest you paid on the loan went up from 2022 to the year you claim
- The loan is from a lender on the Central Bank's list of credit information providers. It was used only to buy, repair, develop or improve the home or to pay off an earlier loan used for that purpose
- For 2023 to 2025 the credit is 20% of the increase in interest over 2022, up to €1,250 per property. For 2026 only half the increase counts, so the most is €625. For example, interest of €14,000 in 2026 against €10,000 in 2022 is a rise of €4,000. Half of that is €2,000 and 20% of that is a €400 credit.
- It only reduces Income Tax. It does not reduce USC or PRSI. If the credit is more than your Income Tax for the year you get a partial refund equal to your Income Tax for that year.
- Only one credit is available per property. Where more than one person pays the interest the credit is split by the interest each paid. If you paid interest for part of a year the credit is prorated.
- A home does not qualify if it is not compliant with Local Property Tax or planning permission. It also does not qualify if you bought it from a connected party at a price well above its value.
- Revenue states the credit is available for 2023 to 2026. 2026 is the last year shown on its pages. You claim for a year after that year ends.
