What is the Rent Tax Credit in Ireland?
The Rent Tax Credit is a relief introduced by the Irish government to help tenants with the cost of renting their home. It allows you to claim back a portion of the rent you pay as a credit against your income tax liability. This means it directly reduces the amount of tax you owe, or can result in a refund if you have already paid enough tax through the PAYE system or otherwise.
How is the Rent Tax Credit Calculated?
The calculation follows a specific set of rules set by Revenue:
- Check Eligibility for 'Digs': If you are in a 'digs' arrangement (renting a room in your landlord's home), your weekly rent must be at least €14 to qualify. If it's less, you cannot claim the credit.
- Determine Eligible Rent: For a standard tenancy registered with the Residential Tenancies Board (RTB), your eligible rent is the total amount you paid in the tax year. For a qualifying 'digs' arrangement, the eligible rent is capped at €15,000 per year, regardless of what you actually paid.
- Calculate 20%: The preliminary credit is 20% of your eligible rent.
- Apply the Annual Cap: This 20% amount is then capped at the maximum credit for the tax year and your claimant type. The maximum was €500 for a single person and €1,000 for a couple in 2022 and 2023. From 2024 onwards, it is €750 for a single person and €1,500 for a jointly assessed couple.
The resulting amount is your Rent Tax Credit. This is a per-tenancy credit. A single tenant claims the full calculated amount for their tenancy, up to the single person's maximum. A couple making a joint claim claims the full calculated amount for their shared tenancy, up to the higher couple's maximum.
Worked Example
Sarah is a single tenant in an RTB-registered apartment. In 2025, she paid €12,000 in rent.
- Eligible Rent: €12,000 (full amount, as it's an RTB tenancy).
- 20% of Eligible Rent: €12,000 * 20% = €2,400.
- Capped at 2025 Maximum for a Single Person: €2,400 is greater than the €750 maximum, so the final credit is €750.
- Sarah can claim a Rent Tax Credit of €750 on her 2025 tax return.
Now consider a couple, John and Mary, sharing the same apartment and paying €18,000 in rent in 2026.
- Eligible Rent: €18,000.
- 20% of Eligible Rent: €18,000 * 20% = €3,600.
- Capped at 2026 Maximum for a Couple: €3,600 is greater than the €1,500 maximum, so their final joint credit is €1,500.
Common Scenarios and Eligibility
Who can claim? You can claim if you pay rent for your principal private residence in Ireland and you are subject to Irish income tax. You cannot claim if you are renting from a parent, or if your tenancy is not at arm's length.
RTB-registered vs. Digs: The 'digs' category is specifically for license agreements where you rent a room in a property that is your landlord's main home. The weekly rent must be at least €14. For these, the annual rent considered is capped at €15,000.
Joint Claims: Couples who are married or in a civil partnership and are jointly assessed for tax can make one claim between them for their shared tenancy. They are entitled to a higher maximum credit than a single person.
Next Steps: Documenting Your Tenancy
To support your claim, Revenue may ask for details of your tenancy and your landlord's information. Having a clear, written agreement is essential. For a standard tenancy, a Residential Lease Agreement formalises the terms, including the rent amount, duration, and responsibilities of both parties. This document provides the evidence you need for your tax credit claim and protects your rights as a tenant. For a 'digs' arrangement, a License Agreement is the appropriate document.
