Maximising Tax Deductions as a Landlord in Ireland
How to legally reduce your rental income tax bill in Ireland. Every allowable deduction explained with practical examples for 2026.
With rental income potentially taxed at up to 52% (40% income tax + 8% USC + 4% PRSI), every euro of legitimate deduction you claim saves you up to 52 cent. Many landlords leave money on the table by missing deductions. Here’s a comprehensive guide to claiming everything you’re entitled to.
The Golden Rule
Only expenses wholly, exclusively, and necessarily incurred in the letting of the property are deductible. Personal expenses or capital improvements are not deductible.
1. Mortgage Interest (Biggest Deduction)
Rate: 80% of interest paid is deductible (increasing to 100% over time under current plans)
This is typically the largest single deduction. The rules:
- Only the interest portion of your mortgage payment is deductible (not the principal)
- The mortgage must be secured on the let property
- Request an annual mortgage statement from your bank showing the interest charged
Example:
- Monthly mortgage: €1,200 (€800 capital + €400 interest)
- Annual interest: €4,800
- Deductible amount (80%): €3,840
Tip: As interest rates change, recalculate this each year. In higher-rate environments, this deduction becomes even more valuable.
2. Repairs and Maintenance
What qualifies: Costs to restore something to its original condition.
| ✅ Deductible | ❌ Not Deductible |
|---|---|
| Fixing a leaking roof | Building a new roof extension |
| Painting and decorating | Installing a new fitted kitchen |
| Replacing like-for-like appliances | Adding a dishwasher to a kitchen that didn’t have one |
| Plumbing repairs | Installing new bathroom from scratch |
| Fixing broken windows | Double-glazing upgrade (capital improvement) |
| Pest control |
Tip: Keep all receipts. Revenue distinguishes between repairs (deductible) and improvements (capital expenditure, not deductible in year).
3. Wear and Tear Allowance
For furnished properties, you can claim 12.5% of the cost of furniture and appliances per year.
| Item | Cost | Annual Claim (12.5%) |
|---|---|---|
| Washing machine | €600 | €75 |
| Fridge-freezer | €800 | €100 |
| Sofa | €1,200 | €150 |
| Beds (×2) | €1,000 | €125 |
| Total | €3,600 | €450/year |
Keep receipts for any furniture or appliances you provide.
4. Insurance Premiums
Fully deductible:
- Landlord building insurance
- Contents insurance (furnished properties)
- Landlord liability/public liability insurance
- Legal expenses insurance
- Rent guarantee/loss of rent insurance
Get a single policy that covers all these — most insurers offer combined landlord policies.
5. Letting and Management Fees
Fully deductible:
- Letting agent finder’s fee (typically 1 month’s rent + VAT)
- Property management fees (ongoing, if you use a management company)
- Advertising costs (listing fees, photography)
- Credit check fees
Tip: If you manage the property yourself, keep a log of time spent — you cannot deduct your own labour, but you CAN deduct any costs you incur (travel, phone calls, postage).
6. Professional Fees
- Accountant/tax advisor fees for preparing your rental accounts and tax return
- Solicitor fees for drafting tenancy agreements (not for property purchase)
- RTB dispute costs — legal and professional fees for RTB hearings
7. RTB Registration Fee
The €90 RTB registration fee per tenancy is fully deductible.
If you have multiple tenancies, you can deduct €90 per registration.
8. Utility Bills
If you pay utilities on behalf of tenants (e.g., in a licence arrangement or where utilities are included in the rent), these are deductible.
However, if you charge tenants separately for utilities, you must also declare those charges as income — so it nets out.
9. Ground Rent
If your property is leasehold and you pay ground rent to a head landlord, this is a deductible expense.
10. Service Charges (Apartment Buildings)
Management company fees for apartment blocks are deductible, including:
- Annual service charges
- Contributions to the sinking fund (building maintenance reserve)
11. Pre-Letting Expenses
Expenses incurred in the year before you first let a property are deductible in the first tax year.
Example: You purchased a property in October 2025, painted it, repaired the bathroom, and first rented it in January 2026. The October–December 2025 repair costs are deductible in your 2026 tax return.
12. Capital Allowances — Pre-Letting Works
Large capital expenditure on a property before it was ever let may qualify for a 15% deduction in the first year, with remaining balance spread over subsequent years.
This is complex — consult a tax advisor for properties that required significant work before letting.
What You CANNOT Deduct
| Item | Reason |
|---|---|
| Mortgage capital repayments | Not an expense (building equity) |
| Property purchase price | Capital expenditure |
| Stamp duty | Capital expenditure |
| Improvements and extensions | Capital expenditure |
| Your own labour/time | Not a cash expense |
| Personal use of property | Not a business expense |
| Fines and penalties | Revenue policy |
Record Keeping Best Practices
Revenue can audit returns up to 4 years back (6 if they suspect fraud). Keep:
- All receipts and invoices (digital copies are fine)
- Bank statements showing rental income received
- Mortgage statements showing interest breakdown
- Tenancy agreements
- RTB registration certificates
- Correspondence with tenants
Use a simple spreadsheet with two tabs: “Income” and “Expenses”. Record every transaction monthly.
The Impact of Good Record Keeping
Landlord A: Doesn’t track expenses properly. Declares €21,600 income, €2,000 estimated expenses. Profit: €19,600. Tax bill: ~€10,192.
Landlord B: Tracks all expenses. Declares €21,600 income, €11,490 in documented expenses. Profit: €10,110. Tax bill: ~€5,257.
Difference: €4,935 saved per year — just by keeping receipts.
Should You Use an Accountant?
When it’s worth it:
- Multiple properties
- Combined rental income over €25,000/year
- Complex situations (mixed use, company ownership, foreign property)
- You have little time or are uncomfortable with tax returns
Cost: €300–€800/year for a straightforward rental return — usually far less than the tax savings from proper deductions.
