Rent-a-Room Relief Ireland 2026: Earn €14,000 Tax-Free Renting a Room
Rent-a-Room Relief lets you earn up to €14,000 per year tax-free by renting a room in your home to a private tenant. No RTB registration needed, no tax return required — as long as you stay under the threshold. Use our Landlord Tax Calculator to see if you're better off with Rent-a-Room or standard letting.
What Is Rent-a-Room Relief?
Rent-a-Room Relief is one of the most generous tax exemptions in Ireland. It allows you to rent out a furnished room in your principal private residence (PPR) and earn up to €14,000 per year completely free of income tax, USC, and PRSI.
The scheme is designed to encourage homeowners to make under-utilised rooms available for rent, increasing the supply of affordable accommodation across Ireland. In 2026, the threshold was increased from €12,000 to €14,000, reflecting rising rental costs and the continued demand for housing.
💡 Key Benefit
Unlike standard rental income — where you pay tax on profit after deducting expenses — Rent-a-Room is a pure exemption. You simply don't pay any tax on the first €14,000. There's no need to track expenses, file forms, or register with the RTB. It's the simplest way to earn rental income in Ireland.
Conditions You Must Meet
Your Principal Private Residence
The property must be your main home — where you live most of the time. You cannot claim Rent-a-Room Relief on a second property, a holiday home, or an investment property. The room you rent out must be in the same house where you reside.
Furnished Room
The room must be furnished when rented out. This means it should have at least basic furniture — a bed, wardrobe, desk, and chair. The room can be used exclusively by the tenant, but you must share the common areas of the house (kitchen, living room, bathroom).
Shared Living Spaces
You must share living accommodation with the tenant. This is what distinguishes Rent-a-Room from a standard landlord-tenant arrangement. The legislation requires that you occupy the same property as the tenant and share the basic living facilities.
Income Threshold
Your total receipts from the arrangement (rent + any payments for meals, laundry, or services) must not exceed €14,000 per year. If they do, the entire amount becomes taxable as standard rental income — not just the excess.
No RTB Registration Needed
Rent-a-Room arrangements are exempt from the Residential Tenancies Act. You do not need to register with the RTB, pay registration fees, or follow RTB dispute procedures. A simple written agreement with your tenant is recommended but not legally required.
Rent-a-Room Scenarios
Understanding the threshold is critical. Here are three real-world scenarios showing how the rules apply:
✅ Under Threshold
| Monthly rent | €1,000 |
| Annual total | €12,000 |
| Threshold | €14,000 |
| Tax payable | €0 |
Fully exempt. No tax return needed.
❌ Over Threshold
| Monthly rent | €1,200 |
| Annual total | €14,400 |
| Threshold | €14,000 |
| Taxable amount | €14,400 |
Entire €14,400 taxed at marginal rate.
⚠️ With Services
| Monthly rent | €900 |
| Meals & laundry | €300 |
| Annual total | €14,400 |
| Threshold | €14,000 |
| Taxable amount | €14,400 |
Services count toward the threshold.
📊 Detailed Example: €1,200/month Rent
You rent out a furnished room in your Dublin home for €1,200 per month. Your tenant shares the kitchen and living room. Total annual receipts: €14,400. Since this exceeds €14,000, the full €14,400 becomes taxable.
| Total rent received | €14,400 |
| Result: Exceeds €14,000 threshold | Entire amount taxable |
| Tax at 40% (higher rate) | €5,760 |
| USC at 8% | €1,152 |
| PRSI at 4.1% | €590 |
| Total tax due | €7,502 |
Key lesson: If you charge €100 less per month (€1,100), you'd earn €13,200 — safely under the threshold and entirely tax-free. That €100 extra per month actually costs you thousands in tax.
Key Rules and Common Pitfalls
🚫 Mortgage Interest Is NOT Deductible
Unlike standard rental income where mortgage interest is a deductible expense (75% deductible from 2026), Rent-a-Room Relief does not allow any expense deductions. This is because it's an exemption scheme, not a deduction scheme. The first €14,000 is simply tax-free — you don't get to deduct costs either. If you exceed the threshold, you move to standard rental rules where deductions are available.
⚠️ The "All or Nothing" Rule
This is the most important rule to understand: if your total receipts exceed €14,000 by even €1, the entire amount becomes taxable — not just the excess. This is a cliff-edge threshold. Planning your rent carefully to stay under €14,000 is essential. If you expect to exceed it, you might be better off treating the arrangement as a standard letting from day one.
🏡 Only One Property
You can only claim Rent-a-Room Relief on your principal private residence. If you own multiple properties, you cannot claim the relief on more than one. The room must be in the home where you ordinarily live. Holiday homes, investment properties, and vacant properties do not qualify.
👨👩👧👧 Multiple Tenants
The €14,000 threshold applies to the total income from all occupants. If you rent out two rooms, the combined rent from both counts toward the single €14,000 limit. You cannot claim €14,000 per room. However, if your spouse or civil partner also resides in the property, you can elect for either of you to claim the relief — but not both for the same arrangement.
