Rent a room relief: the €14,000 limit is all or nothing
Revenue's rent-a-room relief exempts income from letting a room in your own home only where the gross income does not exceed €14,000 a year. Exceed it by one euro and the whole amount is taxable, not just the excess.

Rent-a-room relief exempts income from letting a room in your own home from income tax where the gross income from all such lettings in the year does not exceed €14,000. It is a cliff, not a taper. Exceed the limit by a single euro and the whole of the income becomes taxable, not merely the excess — €14,001 of rent is taxed on €14,001, while €14,000 is taxed on nothing.
Four things that catch people out
1. The cliff. There is no marginal band. A landlord charging €1,170 a month is inside the limit at €14,040 a year — except that they are not, they are over it, and the relief on the entire €14,040 is gone. The arithmetic is worth doing before you agree the fee rather than after, because the fee is what pushes it over.
2. It is a single annual limit, not a limit per room. The relief applies to the total gross income from letting rooms in your home. Two rooms at €650 a month each is €15,600 — over the limit, and both lettings lose the relief together. If you already let one room, count that income before setting the fee for the second.
3. Meals, laundry and utilities count. The limit is measured on gross income. Anything the occupier pays you for meals, laundry or utilities counts towards the €14,000, whether it is rolled into a single monthly figure or invoiced separately. Splitting the payment into "rent" and "a contribution to the ESB bill" does not create headroom.
4. Gross, not net. You do not deduct expenses first and then test against the limit. That is the trade: the relief is generous precisely because it is a flat exemption rather than a computation.
The relief must be claimed
This is the second most expensive mistake after the cliff. Rent-a-room relief is not automatic. You must record the income on your income tax return for the year and claim the exemption — even where the whole amount is exempt and no tax is due. Failing to file the return loses the relief.
So the sequence is: let the room, keep the gross under €14,000, file the return, claim the exemption on it. Skipping the fourth step undoes the first three.
Doing the arithmetic before you sign
| Monthly fee | Annual gross | Position |
|---|---|---|
| €900 | €10,800 | Within the limit |
| €1,150 | €13,800 | Within the limit, with €200 of headroom for utilities |
| €1,167 | €14,004 | Over — the full €14,004 is taxable |
| €650 × 2 rooms | €15,600 | Over — a single limit applies across both |
Where a letting is close to the line, the sensible move is to set the fee so that the annual total including everything the occupier pays you stays at or below €14,000. Reducing a monthly fee by €20 to save tax on €14,000 is not a close question.
What it does not change
Relief is a Revenue question. Whether the occupier is a licensee or a tenant is a Residential Tenancies Act 2004 question, and the two are answered separately.
Letting a room in the home you live in falls outside the Act under section 3(2)(g), so the occupier is a licensee — no Part 4 tenancy under section 28, no RTB registration under section 134, no section 19B deposit cap, no section 66 notice periods and no Part 6 dispute route. That is set out in rent a room: a licence, not a tenancy.
But the relief can still be available for a self-contained part of your home — a converted flat or basement — even though that same self-containment means the occupier is a tenant under the Act, with all of the above applying. Being inside the relief tells you nothing about being outside the Act.
One more point for the occupier: where you claim rent-a-room relief, the person paying you is not entitled to claim rent tax credit in respect of those payments. Say so in the agreement, so it is not discovered in April.
Put it in writing
Our room licence agreement records the rent-a-room position in a dedicated tax clause — the €14,000 gross limit, the all-or-nothing consequence of exceeding it, that meals, laundry and utility payments count towards it, that the relief must be claimed on the return, and the rent tax credit position — and warns you at checkout when the fee you have entered, plus any income from other rooms, puts the annual total over the limit.
