Rental Income Tax Ireland: What Landlords Actually Pay in 2026
Rental Income Tax Ireland: What Landlords Actually Pay in 2026
The most common mistake new Irish property investors make is calculating their rental return using only the 40% income tax rate. They then discover that USC adds another 8% and PRSI adds 4.35%, and what looked like a reasonable yield becomes a number that barely covers the mortgage. The real question is: after tax, are you actually making money?
This is a guide to how rental income is taxed in Ireland in 2026, with worked examples, allowable deductions, and the one tax credit most landlords underuse.
Case V Taxation: The Framework
Rental profits in Ireland are assessed under Case V of Schedule D. This matters because Case V income is not taxed in isolation — it is added to your other income and taxed at your marginal rate. If your salary already exhausts the 20% standard rate band (€44,000 for a single person in 2026), every euro of rental profit is taxed at the top marginal rate across three separate levies.
The three-headed tax on rental income:
Income Tax: 40% on income above €44,000 (single person) or €53,000 (married couple, one income). If your salary is €70,000 and you earn €20,000 in net rental profit, the entire €20,000 sits in the 40% band.
Universal Social Charge (USC): Applied progressively at 0.5% (first €12,012), 2% (€12,012–€28,700), 3% (€28,700–€70,044), and 8% on income above €70,044. If your total income exceeds €100,000 and includes non-PAYE income, an additional 3% surcharge applies, pushing the top USC rate to 11%.
Pay Related Social Insurance (PRSI): Rental income is unearned income, classified as Class K. From October 2026, the Class K rate increases to 4.35%.
The combined top marginal rate: For a higher earner whose salary already puts them in the top brackets across all three levies, the effective marginal rate on rental profit is:
- 40% (Income Tax) + 8% (USC) + 4.35% (PRSI) = 52.35%
If the 11% USC surcharge triggers (non-PAYE income over €100,000), the rate climbs to 55.35%.
This is not a fringe scenario. Any professional earning over €70,000 in PAYE income who receives even €1 in rental profit will see that rental euro taxed at 52.35%.
The Tax on €24,000 Gross Rent: A Complete Waterfall
To understand the real impact, here is the journey from gross rent to net cash in hand for a higher-rate taxpayer:
| Stage | Description | Amount |
|---|---|---|
| Gross Annual Rent | Total received over 12 months | €24,000 |
| Mortgage Interest | 100% deductible (RTB registration required) | -€8,000 |
| Management/Insurance/RTB | Operating expenses | -€2,000 |
| Capital Allowances | 12.5% p.a. on furniture/fittings over 8 years | -€2,000 |
| Taxable Case V Profit | €12,000 | |
| Income Tax @ 40% | -€4,800 | |
| PRSI @ 4.35% | -€522 | |
| USC @ 8% | -€960 | |
| RPRIR Tax Credit | Maximum for 2026 | +€1,000 |
| Net Post-Tax Profit | €6,718 |
From €24,000 in gross rent, a higher-rate taxpayer retains €6,718 after all expenses and taxes. That is a 28% retention rate on gross rent. The deductions are critical — without them, the tax liability would consume even more.
Allowable Deductions: What You Can Claim
The accuracy of your Case V deductions directly determines your tax bill. Revenue is specific about what qualifies:
Mortgage interest: 100% of the interest component of your BTL mortgage is deductible, provided the tenancy is formally registered with the RTB. Note: only the interest element qualifies, not capital repayment.
Management fees: Letting agent fees, property management fees, and advertising costs are fully deductible.
Insurance: Your landlord insurance premium is deductible. Note that standard home insurance is not sufficient — you need a specific landlord policy.
RTB registration fee: The €40 annual registration fee is deductible.
Repairs and maintenance: Routine repairs are deductible. Structural improvements that enhance the property's value are capital expenditure, not deductible as an expense.
Accountancy and legal fees: Professional fees directly related to the letting are deductible.
Capital allowances for wear and tear: Furniture, white goods, and fittings cannot be expensed in full in the year of purchase. They must be claimed at 12.5% per annum over 8 years. A €8,000 furniture fit-out generates a €1,000 allowance per year for 8 years.
What you cannot claim:
- Local Property Tax (LPT) — explicitly excluded
- Your own labour (time spent painting, repairing)
- Post-letting expenses incurred after the tenancy ends
- Expenses during a void period where you are personally occupying the property

Pre-Letting Expenses: The €10,000 Exception
Normally, expenses incurred before a property is first rented are non-deductible. But there is a statutory exception under Section 97A of the Taxes Consolidation Act 1997 that most investors are unaware of:
If a property has been vacant for at least six continuous months before its first letting, the landlord may deduct up to €10,000 in pre-letting expenses against the first year's rental income.
This relief was extended by the Finance Act 2024 through to December 31, 2027. It covers costs like repair work, painting, cleaning, and professional fees incurred while preparing the property for its first tenancy.
For investors renovating a long-vacant property or taking on a probate property that has sat empty, this can provide a meaningful tax deduction in year one. The property must have been genuinely vacant — not between tenancies, but without any residential use — for the full six months prior to letting.
The Residential Premises Rental Income Relief (RPRIR)
The RPRIR is a direct tax credit introduced to incentivise landlords to stay in the market. For 2026 and 2027, the credit is calculated as 20% of your Case V rental income, capped at a maximum absolute credit of €1,000 per year.
The €1,000 maximum credit is reached when your Case V profit reaches €5,000. Above €5,000 of profit, the credit stays at €1,000 regardless of how much more you earn.
Two critical conditions:
First, the credit is applied against Income Tax only — it does not offset USC or PRSI liabilities.
Second, and more dangerously, the credit carries a four-year clawback provision. If you sell the property, change its use (for example, turn it into a holiday home), cease renting it, or transfer ownership within four years of first claiming the relief, Revenue will claw back all the credit you received in prior years.
For investors planning a 3-year hold before selling, claiming the RPRIR and then triggering the clawback effectively means you received a loan from Revenue, not a gift. Do the maths before claiming.
How Lower-Rate Taxpayers Are Taxed Differently
Not every landlord is a high earner. If your total income (salary plus rental profit) stays within the €44,000 standard rate band for a single person, the rental profit is taxed at:
- 20% Income Tax (standard rate)
- PRSI at 4.35%
- USC at 0.5%–3% depending on how much of the income bands you fill
For a single person earning €30,000 in salary and €10,000 in rental profit (after deductions), the rental income may be taxed at approximately 24%–27% combined, rather than 52.35%. The RPRIR credit then has proportionally more impact at this income level.
Calculating Your Own Tax Liability: A Practical Method
Revenue does not have a standalone landlord tax calculator, but you can model your own liability using these steps:
- Start with your gross annual rent
- Subtract all allowable expenses and capital allowances to arrive at taxable Case V profit
- Add the taxable profit to your other income to determine your total income
- Apply the USC rates progressively across the full income
- Apply Income Tax: 20% up to the standard rate cut-off (€44,000 single, €53,000 married one income, or €88,000 for dual-income couples), 40% on the balance
- Apply PRSI at 4.35% on the rental profit portion
- Subtract any applicable tax credits, including the €1,000 RPRIR credit
Revenue will assess your rental income through the self-assessment system. You must file a Form 11 return by October 31 each year for the previous tax year, and pay Preliminary Tax (90% of the prior year's liability, or 100% of the current year's liability) by October 31 as well.

The Bottom Line
The 52.35% marginal rate is not a reason to avoid Irish investment property. It is a reason to model it correctly before you buy.
The investors who get into serious difficulty are those who calculated their expected return at 40% income tax and then discovered, in their first Revenue assessment, that they owed an additional 12.35% they had not provisioned for. Running short on a tax bill in October is far more painful than modelling the correct rate from the beginning.
Maximise every deduction you are entitled to. Register every tenancy with the RTB on time — because mortgage interest deductibility is contingent on this. Claim capital allowances on furniture systematically rather than missing them. And if you are considering selling within four years, think twice before claiming the RPRIR.
The tax treatment of Irish rental income is demanding. But for investors who understand it fully, it is navigable.
