Irish Property Tax / Property Tax Tips

How your mortgage can affect your buy-to-let property tax bill?

Last Updated on October 11, 2024 by Kristina Valcheva

If you’re considering buying a rental property in Ireland, it’s important to understand how the mortgage you choose will affect your buy-to-let property tax bill.

A buy-to-let mortgage is a type of mortgage taken by a person who purchases a property, not as a place to live, but rather as an investment.

Buy-to-let mortgages are different from ordinary residential mortgages because the amount you borrow does not depend on how much you earn.

The arrangement fees on buy-to-let mortgages may be more expensive and the interest rates tend to be higher as well.

In this guide, you will learn the basics of how buy-to-let mortgages work and how you can save money on property tax in Ireland.

How do buy-to-let mortgages work?

Most people take out an interest-only mortgage. This means that they pay the interest on the loan – usually, from the rent they collect – and none of the capital.

The full amount of the mortgage is paid at the end of an agreed term (for example, after you sell the property).

Buy-to-let mortgages are more expensive than typical mortgages and require larger deposits of between 25% and 40%.

A mortgage lender will take several factors into account when working out how much you can borrow, including estimating how much rent you will be able to charge for the property.

The rent that you charge should be at least 25% higher than your monthly mortgage payments.

The lender will also want to ensure that you can afford the repayments, should the interest payment of your mortgage rise.

You need to be confident that your rental income will be enough to cover both your mortgage repayments and your expenses (such as landlord insurance and management fees). You must also keep in mind that there may be periods when the property is empty and you are not earning rental income.

Keep in mind that there is a tax relief on buy-to-let mortgages, that you can use to lower your income tax bill.

What is buy-to-let mortgage interest tax relief?

Buy-to-let tax relief permits property owners to offset mortgage interest payments against their tax bill (in other words – to avail of buy-to-let mortgage tax relief).

Depending on the current regulations in your country, you should typically be able to deduct mortgage interest and other allowable costs from your rental income, before calculating your tax liability.

For example, if you have an Irish mortgage and you pay €5,000 interest for the year, you should be able to deduct this amount from your rental income.

If your rental income is €20,000, your taxable base will be lowered by €5,000, to €15,000.

Meanwhile, if your property is located in the UK, you should know that the situation there changed in 2020.

UK Homeowners in higher tax brackets pay a percentage of their total rental income in tax. In other words, they must pay tax on rental income on the sum before eligible expenses are factored in.

Case Study

Emma has a buy-to-let mortgage on her property that she lets out at £1,100 per month in Braintree. The mortgage is £500 each month or £6,000 per year.

From 6 April 2020, Emma will have to declare that £1,100 as income, or £13,200 per year. Emma earns £45,000 in her job and she is in the higher rate band of tax. For Emma, £8,200 will be taxed at 40% (£3,280) and the first £5,000 will be taxed at 20% – £1000 = £4,280.

The new system from 2020 in the UK returns a tax credit of 20% on the total mortgage interest paid or 20% from 6000 – £1,200.

Once Emma’s tax and mortgage are accounted for, and the credit is applied, her profit for the year will be – (£13,200 – £6,000 – £4,280 + £1,200=) £4,120 for the year.
