For many people in Ireland, becoming a landlord was never part of the original plan.

You might have inherited a property, moved in with a partner and rented out your apartment, or relocated abroad for work and decided to let your home. One way or another, you suddenly find yourself collecting rent, managing tenants, and facing a tax return you weren’t prepared for.

This is what we call the “accidental landlord.”

One of the biggest misconceptions accidental landlords make is believing rental income is passive. From Revenue’s perspective, rental income is treated as business income. If you treat it casually, you’ll almost certainly overpay tax. If you treat it correctly, there are legitimate reliefs that can significantly protect your rental profit.

Below is Intax.ie’s 2026 deep dive into what Irish landlords can and cannot claim—and how to stay compliant while keeping more of your income.

1. The Golden Rule: Repairs vs Capital Allowances

This is the most common—and most expensive—mistake we see on landlord tax returns (Form 11 and Form 12).

Mixing up repairs and capital allowances can not only reduce your refund but also increase your audit risk.

Repairs (Fully Deductible in the Same Year)

Repairs are costs incurred to maintain the property in its existing condition. These are treated as revenue expenses and are deductible in full in the year you pay them.

Examples include:

• Painting and decorating
  
• Fixing broken windows or doors
  
• Boiler servicing and repairs
  
• Plumbing or electrical repairs
  

If it’s fixing what already exists, it’s usually a repair.

Capital Allowances (Claimed Over Time)

Capital allowances apply to goods purchased for the property, such as:

• Furniture
  
• White goods
  
• Beds, sofas, and appliances
  

Instead of claiming the full cost in one year, these items qualify for Wear and Tear allowance at 12.5% per year over 8 years.

Example:

You spend €1,000 on new furniture.

You can claim €125 per year for the next 8 years.

Get this wrong, and you could either lose years of tax relief—or attract unwanted attention from Revenue.

2. The €10,000 Pre-Letting Expenses Opportunity

Normally, expenses incurred before a property is rented are not deductible. However, there is a major exception many landlords miss.

If your property was vacant for at least 6 months before first being let, you may be able to claim up to €10,000 in pre-letting expenses.

This relief—extended until the end of 2027—can cover:

• Insurance premiums while the property was vacant
  
• Repairs and maintenance to prepare the property for tenants
  
• Legal and professional fees
  

The Conditions Matter

To qualify:

• The tenancy must be registered with the RTB
  
• The property must remain rented for at least 4 years
  

If you stop renting within that period, Revenue may claw back the relief. This is an area where professional advice can prevent costly mistakes.

3. The Landlord Tax Credit (RPRIR)

To encourage landlords to remain in the rental market, the government introduced the Residential Premises Rental Income Relief (RPRIR).

This is a direct tax credit against your rental income tax—not a deduction.

• 2025 tax return: €800
  
• 2026 tax return: €1,000
  

There’s no complex calculation involved. If your tenancy is tax-compliant and RTB-registered, you qualify.

Yet every year, many self-filing landlords simply forget to claim it.

4. What You Cannot Claim (Read This Carefully)

To keep your return accurate—and audit-proof—there are certain costs you must never claim:

• Your own labour
  
  You cannot pay yourself for painting, repairs, or maintenance work.
  
• Local Property Tax (LPT)
  
  LPT is never deductible against rental income.
  
• Mortgage interest before letting
  
  
  

Mortgage interest can only be claimed from the date the property is first let or available for letting—not for the months beforehand.

Trying to claim these expenses can trigger Revenue queries and penalties.

Conclusion: Don’t Fear the Form 11

Managing a rental property is already demanding—your tax return shouldn’t add unnecessary stress.

Whether you own one apartment or several properties, the objective is the same:

stay compliant and pay only what you legally owe—nothing more.
