What Is Mortgage Interest Tax Relief?

Mortgage interest tax relief is a tax benefit that allows you to deduct the interest you pay on your mortgage from your taxable income. As a result, you pay less income tax, which lowers your net monthly housing costs.This benefit only applies to the mortgage on your primary residence (the home you live in yourself). Since 2013, the rules have become stricter: you only qualify for interest relief if you also repay your mortgage, for example through an annuity or linear mortgage.If you have an older mortgage (from before 2013), more favourable rules often apply. At Crefin & Partners, we explain clearly how you can make the most of this benefit for your home.

How Does Mortgage Interest Tax Relief Work?

For example, if you have an annuity mortgage of €200,000 with an interest rate of 3%, you pay about €6,000 in interest in the first year. If you fall into a 37% tax bracket, you can deduct that €6,000, resulting in roughly €2,220 less tax payable. That equals about €185 in monthly benefit.As you repay your mortgage, the interest decreases, and so does the tax benefit. The tax authorities provide this benefit through your annual tax return or a provisional tax refund.For mortgages taken out from 2013 onwards, you must fully repay the loan within 30 years to remain eligible for tax relief. Our mortgage advisors are happy to calculate free of charge what this means in your specific situation.

Advantages of Mortgage Interest Tax Relief

Mortgage interest tax relief offers several significant benefits:

  • Lower net monthly costs, especially in the early years of your mortgage
  • Extra financial room for other expenses, such as furnishing your home
  • Long-term benefit: you can benefit for up to 30 years
  • Especially helpful for first-time buyers purchasing their first home

Our mortgage advisors help you make the most of this advantage.

Disadvantages of Mortgage Interest Tax Relief

There are also some limitations:

  • For mortgages from 2013 onwards, repayment is required to qualify
  • The benefit decreases as you repay more of your mortgage (since interest declines)
  • Lower tax brackets result in less benefit (for example after retirement)
  • Maximum of 30 years of tax relief for mortgages taken out from 2001 onwards

At Crefin & Partners, we advise you on how to combine tax relief with the right mortgage structure.

Who Benefits Most From Mortgage Interest Tax Relief?

Mortgage interest tax relief is especially relevant for:

  • First-time buyers purchasing their first home
  • Home movers taking out a repayment mortgage
  • Homeowners with older mortgages from before 2013 (often more favourable rules)

Our mortgage advisors review your personal situation and income to ensure you benefit as much as possible.
