Mortgage interest relief – ended 31 December 2020

Mortgage interest relief was a tax relief that was in operation until the end of 2020. Homeowners could claim tax relief on the interest paid on a qualifying mortgage loan in a given tax year.

The mortgage had to have been taken out between 1 January 2004 and 31 December 2012. This tax relief came to an end in 2020.

Qualifying mortgage loans included:

• A new mortgage for a home
• A mortgage top-up used to develop or improve the home
• A separate home loan used to develop or improve the home
• Re-mortgage or consolidation of existing loans

You could claim relief if you lived in Ireland but worked in the United Kingdom.

Your lender applied the relief through the Tax Relief at Source (TRS) scheme either by reducing your mortgage repayment by the amount of tax relief you were due, or as a credit into the account you repaid your mortgage from.

Different thresholds and rates of relief were available depending on whether you were a first-time buyer and whether you were single or married, in a civil partnership, widowed or a surviving civil partner.
