Irish rental income is taxable, whether you are a private landlord, accidental landlord, or invest in property as part of your long‑term financial planning. Understanding how rental income tax works can help you claim all available deductions and avoid unnecessary Revenue issues.
This guide explains what counts as rental income, which expenses are allowed, and how to calculate and declare your rental profits.
What Counts as Rental Income in Ireland?
Rental income is not just the basic rent. For Irish tax purposes, rental income includes:
- Rent from houses, apartments, flats and other residential properties
- Rent from commercial properties (offices, shops, units)
- Payments from tenants for use of land or farmland
- Certain payments for rights over your property (e.g. wayleaves, advertising signs, masts, sporting rights)
- Payments from tenants that cover work or repairs on the property (where the lease does not require them to pay)
All of this income is combined to calculate your yearly rental profit or loss.
Allowable Rental Expenses
You are taxed on net rental profit, not on gross rent. To get to your taxable rental income, you can deduct allowable expenses such as:
- Mortgage interest on loans used to purchase, improve or repair the rental property (100% deductible, provided all tenancies are registered with the RTB and the property is actually let)
- Repairs and maintenance (not including capital improvements)
- Insurance on the rental property
- Letting and management fees (estate agent or property manager fees)
- Legal and accountancy fees related to the letting
- Rates and local charges payable by the landlord
- Wear and tear on furniture and fittings (capital allowances, typically at 12.5% per year on qualifying items)
- Advertising costs for finding tenants
- Other day‑to‑day costs incurred wholly and exclusively for the rental business
Expenses that are partly private and partly business must be apportioned on a reasonable basis.
Mortgage Interest Deduction
Landlords can deduct 100% of the interest on eligible mortgages used to:
- Buy the rental property
- Improve or repair the rental property
Key points:
- The property must be let – interest is only deductible for the period it is rented
- You must register all tenancies with the RTB to claim the deduction
- Interest is treated as accruing daily, so timing of letting periods matters
This deduction can significantly reduce your taxable rental profit.
Rent a Room Relief vs Rental Income
If you rent out a room or self‑contained flat in your own home, you may qualify for Rent a Room Relief:
- Up to €14,000 per year of gross receipts can be exempt from income tax
- Covers rent and certain related services (e.g. bills, meals, laundry)
- Does not apply to short‑term guest‑type lettings
Where Rent a Room Relief applies, the income is treated differently and is not taxed under the standard rental income rules, provided you stay within the threshold and all conditions are met.
Temporary Rental Income Tax Relief for Landlords (RPRIR)
From 2024, a temporary Residential Premises Rental Income Relief (RPRIR) was introduced to support private landlords. This relief gives an income tax reduction on qualifying rental income from residential tenancies that meet specific conditions.
Landlords should:
- Confirm their tenancies qualify (for example, property type, tenancy duration and registration requirements)
- Ensure they remain compliant with all landlord obligations to retain the relief
- Review annually how the relief interacts with their overall income tax position
Multiple Rental Properties
If you own more than one rental property:
1. Calculate the profit or loss for each property separately (rent less allowable expenses, including mortgage interest and wear and tear).
2. Add all profits and losses together to get your net rental income for the year.
3. The combined figure is then taxed at your marginal income tax rates, plus USC and PRSI where applicable.
Losses from one Irish rental property can usually be offset against profits from another Irish rental property in the same year or carried forward against future rental profits.
How Rental Income Is Taxed
Once you have calculated your net rental profit:
- It is added to your other income (salary, self‑employed income, pensions, etc.)
- Taxed at 20% up to your standard rate band and 40% above that
- USC and PRSI may also apply, depending on your circumstances
Reliefs and tax credits (e.g. personal, employee or earned income credits) help reduce your overall income tax bill but are not ring‑fenced to rental income only.
Declaring Your Rental Income
You must declare Irish rental income to Revenue:
- Form 11 – if you are self‑assessed (or your net rental income exceeds €5,000)
- Form 12 – if you are a PAYE taxpayer with net rental income below the relevant threshold
- Form CT1 – if the rental property is owned by a company
You should maintain accurate records of:
- Rental agreements and RTB registrations
- All rent received (including deposits retained where taxable)
- Invoices, receipts and statements for every expense claimed
- Mortgage statements showing the interest element
Revenue can request evidence to support your figures in the event of a review or audit.
