The headline says Airbnb, and the headline is lying to you. Airbnb vs long term let Dublin comparisons usually stop at gross revenue, and that is the first mistake. Rent a well-rated central Dublin one-bed on Airbnb at €120–€180 a night and, at 70% occupancy, it grosses roughly €2,500–€3,800 a month against €1,800–€2,500 for the same property on a normal twelve-month tenancy. That gap — often €1,000 a month before you spend a cent — is why every second property-investor reel on your feed is about “short-term rental income.” But gross revenue is not profit, and profit is not the whole question. Dublin in 2026 has three layers of reality under that revenue gap: the cost layer (fees, cleaning, turnover, insurance), the legal layer (the 90-day rule, planning permission for second properties, and a new Fáilte Ireland register that lands on 31 December 2026), and the tax layer (same income tax bands as a long-term let, a very different VAT world, and no Rent-a-Room relief for guest income). This guide runs a Dublin 2 apartment both ways, line by line, and tells you which strategy genuinely earns more after the rules, the running costs and the risk — and for whom.
TL;DR: On the classic Airbnb vs long-term let Dublin question — which strategy earns more — gross revenue has a clear first answer: a compliant short-term let in Dublin’s tourist core out-earns a long-term tenancy by roughly 25–40% — a central one-bed grossing about €3,000/month on Airbnb at 70% occupancy versus €2,000/month on a twelve-month lease. After platform fees, cleaning, utilities, higher insurance and turnover, the edge shrinks to about €200–€350 a month before income tax (our D2 worked example: ≈€1,800 net vs ≈€1,500), and after tax at the 40% rate the gap is closer to €150–€200. Meanwhile the legal ceiling is unforgiving: your own home can be let for at most 90 nights a year without planning permission, a second property needs change-of-use planning permission that Dublin City Council rarely grants, and every short-term unit must be registered with Fáilte Ireland by 31 December 2026 or be de-listed and fined. Airbnb wins for a narrow set of centrally located, legally sorted, hands-on operators; the long-term let wins for almost everyone else — and the mid-term corporate let (1–6 months) is the compromise strategy that captures much of the Airbnb premium with a fraction of the turnover and risk. Details, tables and the full D2 worked example below.
The headline numbers: what each strategy grosses, side by side
Short-term letting in Dublin in 2026 is a seasonal, platform-driven income business; long-term letting is a twelve-month contract business. The two revenue models are built differently, so compare them on the same monthly basis. Any honest short term rental Dublin 2026 projection starts from the same two numbers — the nightly rate and the occupancy rate — because together they are the revenue.
The Airbnb side. AirDNA’s 2026 Dublin market data shows about 4,500 active short-term listings (Airbnb, Vrbo and Booking.com combined) averaging roughly 65% occupancy at a blended average daily rate (ADR) of about US$200 (≈€185) — a figure dragged up by larger premium homes (AirDNA Dublin overview). For a typical well-rated one- or two-bed in the tourist core, €120–€180 a night is the realistic planning range in 2026 — higher at peak summer and for event weekends, lower mid-winter. At the 70% occupancy investors underwrite, that is about 21 occupied nights a month:
| Occupied nights/mo (at ADR) | €120/night | €150/night | €180/night |
|---|---|---|---|
| 17 nights (~55%, weak winter month) | €2,040 | €2,550 | €3,060 |
| 21 nights (~70%, blended year) | €2,520 | €3,150 | €3,780 |
| 24 nights (~80%, strong summer) | €2,880 | €3,600 | €4,320 |
So the €2,500–€3,800/month gross band in the opening paragraph is exactly the €120–€180 × 70%-occupancy row. Occupancy is the swing factor: Dublin’s tourism core runs 80–90%+ occupancy from June through September and around big events, and can drop to 40–60% in November–February — a €3,000-month followed by a €1,400-month is normal, not a crisis.
The long-term side. Market rents for the same central stock: Dublin one-beds let around €1,900–€2,100/month and two-beds around €2,300–€2,700/month in 2026 — the average Dublin two-bed was €2,634/month in Q2 2026 (Daft.ie Rental Report via RTÉ; see our average rent guide). The €1,800–€2,500 band covers a central one- or modest two-bed, and it arrives every month, January included, with a signed contract, a deposit and the RTB Rent Register behind it.
| Strategy (central Dublin 1-bed) | Gross monthly revenue | Occupancy dependency | Cash-flow shape |
|---|---|---|---|
| Airbnb @ 70% occupancy, €120–€180/night | €2,500–€3,800 | Very high — revenue swings with season, events and reviews | Lumpy: strong Jun–Sep, weak Nov–Feb |
| Long-term let @ market rent | €1,900–€2,100 | None after the first letting (voids typically <1 month/yr) | Flat and predictable, 12 months |
The honest first read: Airbnb grosses 30–80% more per month than a long-term let on the same property — before you subtract anything. Everything below is the story of how much of that survives contact with reality.
The cost differential: where Airbnb’s revenue premium disappears
Short-term letting is a hospitality operation wearing a property’s clothes. The cost lines that are near-zero on a long-term let are core expenses on Airbnb. The table below is the monthly cost stack for a self-managed central one-bed on each strategy (author estimates, mid-case 2026; your numbers will differ):
| Cost line | Airbnb (self-managed) | Long-term let | Notes |
|---|---|---|---|
| Platform / agency fee | 15.5% of bookings (Airbnb’s single host-only service fee since the late-2025 migration; hosts still on the old split model pay ~3% + a guest fee) | 0% direct (or 7–10% if you use a letting agent) | Airbnb’s fee applies to the booking subtotal including your cleaning fee |
| Cleaning & linen | €40–€55 per turnover — 8–12 turnovers a month at 2–3-night average stays ≈ €350–€600/mo | Near zero (tenant maintains; you clean between tenancies) | Linen wears out 3–4× faster with guest cycles |
| Utilities, wi-fi, consumables | €150–€250/mo — you pay them year-round between bookings | €0 (tenant pays; empty period is a void) | Guest heating habits + laundry loads add up |
| Insurance | Premium uplift of €40–€100/mo for proper short-let cover | €0 uplift (standard landlord cover) | Standard home/landlord policies exclude guest occupation; Airbnb’s AirCover is not a substitute for a real policy |
| Maintenance & wear-and-tear | €80–€150/mo — turnover traffic, lost keys, breakages, faster decor refresh | €50–€100/mo equivalent, smoothed | Expect to re-furnish a short-let unit every 2–3 years |
| Management (if outsourced) | 20–30% of gross revenue for a full-service short-let manager | 7–10% of rent for a letting agent | The single biggest “should I self-manage?” lever |
| Total operating cost | ≈€750–€1,100/mo self-managed (or 20–30% of gross if managed) | ≈€400–€600/mo | Airbnb’s revenue premium of ~€1,000/mo shrinks to ~€300–€600 before it reaches your bank |
The arithmetic consequence: a €3,000-month Airbnb gross and a €2,000-month long-term rent land within a few hundred euro of each other after operating costs — and if you outsource the Airbnb to a manager at 25%, the managed Airbnb nets less than the self-managed long-term let. The premium is real money, but it is earned, in cleaning visits, check-in messages, review management and 2 a.m. boiler calls. Price your own time honestly before you call it “passive.”
Regulatory: what Dublin actually allows in 2026 (the 90-day rule, planning permission, and the register)
This is the section that filters out most would-be Airbnb investors — and it is the entire answer to most short term letting rules Dublin 2026 searches — so read it before the revenue tables seduce you. The rules sit in three separate stacks: the planning rules (what you may use the property for), the registration rules (the Fáilte Ireland register arriving this December), and — for long-term lets only — the rent-control rules that changed on 1 March 2026. The rent-cap reform did not touch the planning rules below; it governs tenancies, and short-term guests are not tenants.
What counts as a “short-term let” in 2026
Ireland’s new national regime — built on the Short-Term Letting and Tourism Bill (General Scheme approved April 2025, implementing the EU Short-Term Rental Regulation 2024/1028) — defines a short-term let as accommodation let for up to 21 nights at a time (DETE — Short-term letting). If you take guests for 21 nights or fewer — a weekend, a week, three weeks — you are running a short-term let. Stays longer than 21 nights sit outside the register’s definition (more on the 1–6 month band in the hybrid section).
The rule that matters first: the 90-day ceiling on your own home
For your principal private residence (PPR), the law draws a sharp line between homesharing and whole-home letting:
- Letting a room (or rooms) in the home you live in — homesharing — is unrestricted. There is no day cap and no planning permission requirement (DETE; Citizens Information).
- Letting your entire home while you are temporarily away is capped at 90 cumulative nights per calendar year without planning permission. Exceed 90 days — counted across all platforms combined — and you need change-of-use planning permission (Citizens Information).
This 90-day rule is the arithmetic killer for most “Airbnb my home” plans: at €150 a night, 90 nights grosses €13,500 a year — about €1,125 a month averaged across the year — before costs, which is below a long-term let on the same property. The €2,500–€3,800-a-month Airbnb revenue in this article’s headline is only available to properties that can legally run year-round — which means they are not your home, they have planning permission, or you are operating outside the rules and rolling the dice described below.
The second-property gate: planning permission for change of use
A second property — anything that is not your principal private residence — cannot be let short-term in Dublin without planning permission for a change of use from residential to short-term tourist letting. This has been the rule since the 2019 short-term letting regulations (introduced precisely to push tourist lettings back into Dublin’s long-term rental market), and it is unchanged in 2026:
- Dublin City Council treats a change-of-use application on its housing-stress test: permission is unlikely where the area has high rent pressure, insufficient supply and heavy demand — which describes essentially all of Dublin (Citizens Information).
- Applications typically take about 8 weeks to decide; running without permission is an offence under the Planning and Development Act 2000, enforceable by warning and enforcement notices, fines and prosecution.
- A new National Planning Statement on short-term letting (issued under the Planning and Development Act 2024) goes further: it restricts the approval of new planning permissions for short-term lets in cities and larger towns with a population over 20,000 — Dublin City included — while giving providers in smaller towns (≤20,000) two years to reach compliance (DETE).
- Existing properties that can show seven continuous years of short-term letting without enforcement action have a presumption in favour of permission, and a simplified retention process is being introduced — but for a new investor buying today to run a second home on Airbnb, the planning gate in Dublin is effectively closed.
The uncomfortable truth about today’s Dublin listings: repeated council and media investigations have found that a majority of Dublin’s short-let listings have lacked the planning permission they needed — and enforcement was historically thin. That era ends with the register (below), which is precisely why the risk profile of buying a second property for Airbnb changed in 2026.
The Fáilte Ireland register: the 31 December 2026 deadline
Ireland’s national short-term letting register, run by Fáilte Ireland, opens on 1 December 2026 — and every host letting accommodation for up to 21 nights must be registered by 31 December 2026 (DETE; Citizens Information). What it means:
- Registration is online, annual, at a nominal fee, and covers whole homes and rooms let in your own home. You get a unique registration number that must appear on every listing and advertisement.
- You must declare planning compliance as part of registration — which is how the register turns the planning rules into something enforceable at scale.
- Platforms (Airbnb, Booking.com, Vrbo) must display the number and may only list registered units. From 31 December 2026, Fáilte Ireland can order a platform to suspend or remove any listing without a valid number, and platforms that fail to comply face penalties reported to run up to 2% of turnover.
- Hosts who don’t register face Fixed Payment Notices (fines) and legal action; your unit also lands on the public register, so Revenue can cross-check declared income against registered units (platforms already auto-report host earnings to Revenue under DAC7).
- Some secondary sources still cite a “20 May 2026” launch — that earlier date was superseded; the current official position (checked 5 September 2026) is open 1 December 2026, register by 31 December 2026.
The one-line read: as of 1 January 2027, an unregistered Dublin short-let listing is a fineable, de-listable, publicly visible compliance problem — and a second-property listing without planning permission cannot truthfully complete the registration declaration at all. The rules our rent-cap explainer describes govern long-term tenancies; these rules govern everyone else, and they now have teeth.
| Scenario | Legal in Dublin 2026? | What you need |
|---|---|---|
| Let a room in your PPR while you live there | Yes, unlimited nights | Fáilte Ireland registration by 31 Dec 2026; income taxed (no Rent-a-Room relief for guests) |
| Let your whole PPR while away | Yes, up to 90 nights/yr | Track the 90 days across all platforms; register by 31 Dec 2026 |
| Let your whole PPR beyond 90 nights/yr | No — needs planning permission | Change-of-use permission (rarely granted in Dublin) |
| Let a second property short-term | No — needs planning permission | Change-of-use permission; new permissions restricted in cities >20,000 |
| Let to one tenant on a normal lease | Yes | RTB registration within a month; 2% rent-cap regime applies |
Tax: same income tax bands, a very different VAT world
The brief version most people hear — “the tax is the same” — is true only at the level of the income tax bands. Below that, short-term and long-term letting are taxed differently in ways that matter at exactly the revenue levels this article is about.
Income tax: same marginal bands, different classification. Whatever strategy you choose, the profit lands in your income tax return and is taxed at your marginal rate — 20% or 40% income tax, plus USC and PRSI, up to the 52% top marginal rate that dominates every Irish property-investment conversation. But Revenue does not treat the two incomes alike:
- Long-term rent is rental income (Case V), with the familiar rules — including the important fact that mortgage-interest relief requires an RTB-registered tenancy (see our buy-to-let reality check).
- Short-term let income is not rental income at all — your visitors are guests, not tenants (Citizens Information). Where you provide services (cleaning, linen, guest management) to a degree that makes the activity a trade, Revenue treats it as trading income, with broader expense relief but different rules and PRSI consequences; a very light-touch arrangement can fall into “other income.” The classification follows the reality of what you do, not what you call it — your accountant should rule on your exact setup before your first return.
- Rent-a-Room relief does not help Airbnb hosts. The €14,000-a-year tax exemption for letting rooms in your PPR applies only to residential lettings; Revenue has confirmed that income from short-term guest accommodation (including via booking platforms) does not qualify (Revenue; Irish Tax Hub). That homeshare room earning €10,000 a year on Airbnb is taxable — the same €10,000 to a lodger with a normal lease would be exempt. If you searched “airbnb income Ireland” hoping Rent-a-Room would shelter your guest income, that is the myth to drop first: Revenue’s position is clear that short-term guest income does not qualify.
VAT: the real tax difference. This is where the strategies diverge structurally:
- Long-term residential letting is exempt from VAT. A landlord charging €2,000 a month rent never registers, never charges VAT, and has no VAT admin.
- Short-term accommodation is VAT-able at the 13.5% reduced rate (the July 2026 cut of hospitality VAT to 9% covers restaurant and catering services — not hotel or short-stay accommodation, which stays at 13.5%).
- VAT registration becomes mandatory once your turnover exceeds €42,500 in any rolling twelve-month period — the services threshold that has applied since 1 January 2025, when Revenue raised it from €40,000 (and, before 2023, €37,500 — the figure still quoted on some older guides).
Do the maths on that threshold: a Dublin one-bed at €150/night crosses €42,500 at about 285 occupied nights a year — roughly 78% occupancy. A serious, compliant, year-round short-let operator is therefore very likely VAT-registered, charging 13.5% on stays, filing VAT returns and reclaiming VAT on expenses; the small host doing 60–90 PPR nights a year stays under the threshold and does not charge VAT. (Platform VAT collection and remittance mechanics vary by platform and listing setup — verify yours with an accountant, because getting this wrong is the most common Airbnb tax surprise.)
The tax bottom line: income tax is a wash between the strategies; VAT is not. If you scale short-term letting past the €42,500 line you inherit a VAT compliance layer that a long-term landlord never touches — and it arrives because the gross revenue is higher.
Worked example: a Dublin 2 one-bed, run both ways
Let’s put real numbers on it. Dublin 2 — the Trinity/Grafton Street/Temple Bar core — is Dublin’s densest short-let micro-market, the kind of postcode where the Airbnb model is supposed to win. The example property: a good-condition one-bed apartment bought around the €395,000 D2 median (see our rental yields by area table), let either way. Both columns are net after operating costs, before income tax, on mid-case September 2026 assumptions — income tax is applied at the end because it is the same marginal-rate conversation for both.
| Line | Long-term let | Airbnb (70% occupancy) |
|---|---|---|
| Monthly revenue | €2,000 (D2 one-bed market rent) | 21 nights × €145 avg = €3,045 gross bookings |
| Platform / letting fee | −€140 (7% agent; €0 if self-managed) | −€472 (15.5% Airbnb host-only fee) |
| Cleaning & linen | − | −€400 (~10 turnovers × €40) |
| Utilities, wi-fi, consumables | − | −€180 |
| Insurance & LPT | −€120 | −€180 (short-let premium uplift included) |
| Maintenance, voids, letting costs | −€240 (incl. ~2 weeks’ void & compliance) | −€80 |
| Net before income tax | ≈€1,500/month | ≈€1,730–1,830/month (call it ≈€1,800) |
| Income tax at 40% | −€600 | −€720 |
| Net after 40% tax | ≈€900/month | ≈€1,080/month |
| Income tax at the 52% top rate | −€780 | −€940 |
| Net after 52% tax | ≈€720/month | ≈€860/month |
Author calculation, September 2026, mid-case assumptions (self-managed Airbnb, agent-managed or self-managed long-term per your time budget). Your ADR, occupancy, cleaning costs and tax rate will move every line — the shape will not.
Read that twice, because it overturns the headline:
- The revenue gap is ~€1,000/month; the after-operating-cost gap is ~€300; the after-tax gap is ~€150–€200. Income tax at 40–52% compresses both strategies toward each other because the higher-earning strategy pays proportionally more tax.
- The Airbnb column assumes ~70% occupancy achieved and held year-round — which means a listing with a deep review history, top-tier location and professional guest operation. New listings with zero reviews commonly run 40–50% occupancy for their first months while the platform algorithm and review count build.
- The Airbnb column assumes the property is legally running year-round — i.e., it is a second property with change-of-use planning permission, which Dublin is now effectively not granting to new applicants. Without that permission, the honest comparison is the 90-night PPR version: 90 nights × €145 = €13,050 gross a year → ≈€700–€800 a month after operating costs — below the long-term let, before you count a single tax euro.
- If you outsource the Airbnb to a manager at 20–25% of gross (the Dublin going rate for full-service short-let management), the Airbnb column loses another €600–€750 a month and lands below the long-term let. The premium only survives self-management.
- The property itself performs identically either way — same capital growth, same LPT, same 33% CGT on exit (PPR exemption aside). The letting strategy changes income and workload, not the asset’s trajectory. For the district-level numbers behind that, the rental yields table and the buy-to-let reality check are the companion reads.
Risk: what the revenue tables don’t show
If the money gap is only ~€200 a month after tax, the decision is really a risk comparison. The Airbnb strategy’s risks are broader and less insurable than a long-term tenancy’s:
- Compliance risk (the big one). The Fáilte Ireland register deadline (31 Dec 2026), the planning-compliance declaration, and platform de-listing powers convert years of tolerated non-compliance into a data-led enforcement machine. A second-property host without planning permission cannot register truthfully; the realistic endgame is de-listing, Fixed Payment Notices, council enforcement and possibly prosecution under the Planning and Development Act. This risk was always present; 2026 is when it acquired a database.
- Regulatory-change risk. The full Short-Term Letting and Tourism Bill is still moving through the Oireachtas; the National Planning Statement is new; Budget 2027 lands on 6 October 2026 and could touch short-let tax treatment, reliefs or thresholds. Anyone underwriting a short-let purchase today is underwriting rules that are still being written.
- Seasonality and cash-flow lumpiness. November–February occupancy of 40–60% means the mortgage, management fees and insurance keep billing while the calendar doesn’t. You need a working-capital buffer that a long-term landlord simply doesn’t.
- Platform risk. Airbnb moved most hosts to a 15.5% host-only fee in the late-2025 migration, and can move them again. Algorithm changes, review-score cliffs (one bad guest can cost you ten bookings), account suspensions, and local policy shifts are outside your control. Your “business” is a listing on someone else’s platform.
- Market-supply risk. Dublin already has ~4,500 active short-let listings; every new listing competes with established review-rich units, and new entrants suffer a cold-start period of low placement and low occupancy.
- Property-level restrictions. Apartment management companies and head leases frequently forbid subletting (common minimums: no lets under 6 or 12 months, or none at all); your mortgage may prohibit short-term letting (residential mortgages certainly do — and banks are reluctant to lend on a short-let business plan at all); standard landlord insurance excludes guest occupation, and claiming on a policy that doesn’t cover your actual use is how people end up uninsured.
- Operational risk. Turnover damage, neighbour and noise complaints, refuse issues, guest safety and fire-safety duties, key handling at 11 p.m., and the sheer time cost of a hospitality business. Dublin City Council acts on complaint-driven enforcement.
- Tax and data risk. DAC7 means platforms hand your earnings to Revenue automatically; under-declared Airbnb income is now one of the easier things for Revenue to find. The VAT registration line at €42,500 adds filing obligations exactly when you’re doing well.
The long-term let’s risk list is shorter and mostly familiar from our buy-to-let reality check: tenant disputes, the 2% in-tenancy rent cap, void risk between tenancies, and the compliance spine of RTB registration. All of it is slower-moving, contract-based and — critically — insured and financed on well-worn rails.
When Airbnb genuinely wins
There is a short list of situations where the short-term let is the better strategy, and they all share three features: the property is in a proven tourist micro-location, the operator can legally run year-round, and someone hands-on is managing it.
- Tourist zones D1, D2 and D8. The city-centre core — Temple Bar and Trinity (D2), the O’Connell Street/Docklands/IFSC area (D1), and the Liberties/Guinness Quarter corridor (D8) — is where Dublin’s short-let demand concentrates and where 70–85% occupancy is achievable for a top-rated unit. The research brief behind this series pegged short-term revenue in these hotspots at €2,500–€4,500/month in peak season, planning rules aside.
- The events calendar. St Patrick’s Festival, Six Nations and autumn internationals at the Aviva, summer concert runs at Croke Park, Aviva and the 3Arena, GAA finals, and the conference calendar at the Convention Centre all spike ADR and occupancy to 90%+ for stretches of the year. A calendar-savvy host prices these peaks dynamically; a long-term lease just watches them happen.
- A PPR you’ll use yourself. If you want the flexibility to live in the property between guests — and you’re content with the 90-night ceiling — homesharing (a room) is genuinely unlimited, and whole-home lets up to 90 nights gross ~€13,000 tax-managed carefully. It’s a side income that also covers your home while you travel, not an investment strategy.
- One-bed units near the tourist core, where the nightly-rate-to-price ratio is best and the guest profile (couples, short-break tourists, business travellers) is the easiest to serve well.
- You will self-manage and you genuinely enjoy hospitality. The premium only survives self-management; if you’d outsource it, the long-term let wins on net income per hour of your life.
For a purchase decision — buying a property specifically to run short-term — the test is brutal: can this property legally let year-round? If the answer is “no” (second property without permission — i.e., almost every new purchase), the Airbnb revenue model in this article is not available to you, whatever the spreadsheets say.
When the long-term let wins
For most Dublin investors in 2026, the long-term let is the better strategy — and the reasons are now structural, not just temperamental:
- Predictable income under a predictable rulebook. Since 1 March 2026, in-tenancy rent rises are capped at the lower of CPI or 2% a year — so a long-term let’s income is known: it compounds at ~2%, arrives 12 months a year, and resets to market when the tenancy turns over (rent-cap explainer). The 2% cap that landlords complain about is precisely what makes long-term cash-flow bankable.
- Dramatically lower running costs and effort. No 15.5% platform fee, no turnover cleaning, no utilities, no premium insurance — and an agent can run it for 7–10% while you sleep.
- Financing works. Banks lend against long-term tenancy income; RTB-registered tenancies unlock mortgage-interest relief; residential and buy-to-let mortgage products assume a tenant, not a guest stream. A short-let business plan is harder to finance, and a residential mortgage used for short lets is a breach of terms.
- The legal and compliance path is boring and clear. RTB registration, the rent-review routine, minimum standards — all well-documented, all stable, none of it dependent on a register that opens in December or a Bill still in the Oireachtas.
- The maths is honest. Dublin’s registered-rent gross yields of ~7–10% in the inner city (see the yields table) already underwrite a decent net return on a long-term let — and the ~€200-a-month after-tax Airbnb premium in our worked example does not compensate for the compliance, seasonality and platform risk stacked on top of it.
- Exit liquidity. A property with a compliant long-term tenancy sells into the deepest buyer pool (investors and, at the end of a tenancy, first-time buyers); a short-let unit carries the question “can the buyer continue the use?” into every negotiation.
The long-term let is the default answer for anyone who wants rent, not a job.
The hybrid: mid-term lets (1–6 months) for corporate and academic demand
There is a third strategy that captures much of Airbnb’s revenue premium while sidestepping most of its costs and rules: the mid-term let of one to six months — corporate relocations, project contractors, visiting academics, hospital and nursing staff, and students on placements.
Why it works in the 2026 rulebook:
- It sits outside the short-term letting definition. The Fáilte Ireland register polices lets of up to 21 nights. A genuine one-to-six-month let is not a “short-term letting unit” for registration purposes — no STL number, no platform-listing declaration, no 90-day-counting treadmill.
- It keeps the furnished premium. A fully furnished, wi-fi-enabled apartment that rents to a relocating professional at €1,900–€2,800/month (depending on size and season) is priced above the unfurnished long-term market rent for the same unit — corporate and academic tenants pay for “turn-key.”
- It collapses the operating cost. One to four turnovers a year instead of ten a month: no constant cleaning, no utility churn between guests, minimal wear and tear, standard landlord insurance closer to a normal buy-to-let policy.
- It smooths the seasonality. Corporate and academic calendars run September–June (academic) and year-round (corporate), which is the inverse of tourist seasonality — a summer tourist let + a September–June academic let can fill a year that pure tourism can’t.
The honest caveats: the longer the let, the more it looks like a residential tenancy — once a let runs past six months, Part 4 security of tenure and the full RTB framework attach, so mid-term agreements should be written and priced as fixed-term lets with professional legal input, and registered with the RTB where they qualify. Apartment management companies may define “short let” as anything under 30 days (fine for mid-term) or ban subletting outright (check your lease and head lease). And a series of three-week corporate lets is still short-term letting in substance, whatever the paperwork says — authorities follow reality, not labels.
The sweet spot is a D1/D2/D7/D8 furnished one- or two-bed near the corporate and institutional belt (IFSC/Docklands, the universities, the major hospitals), marketed through relocation agents and the platforms’ 30+ night filters rather than the tourist channel. It is the strategy that fits the 2026 regulatory picture best: above the short-let register, below the full-tenancy weight, priced between the two.

Which earns more in Dublin in 2026 — Airbnb or a long-term let?
On gross revenue, Airbnb wins clearly: a central one-bed grosses about €2,500–€3,800/month at €120–€180/night and 70% occupancy, versus €1,900–€2,100 on a long lease. After platform fees, cleaning, utilities, insurance and turnover, the edge shrinks to roughly €200–€350 a month before income tax (≈€1,800 net vs ≈€1,500 in our D2 example) and to ~€150–€200 after tax at 40%. Against that premium you must set the legal ceiling — 90 nights a year for your own home, planning permission for a second property — and materially higher operational and regulatory risk. For most investors the long-term let wins on risk-adjusted, after-tax, after-effort return; the mid-term corporate let (1–6 months) is the compromise.
Is Airbnb legal in Dublin in 2026?
Homesharing — letting rooms in the home you live in — is legal and unrestricted. Letting your whole principal private residence is legal for up to 90 cumulative nights a year without planning permission. Letting a second property short-term requires change-of-use planning permission, which Dublin City Council rarely grants and which national policy now restricts in cities over 20,000 population. From 1 December 2026 every short-term unit must be registered with Fáilte Ireland, with registration completed by 31 December 2026.
Can I Airbnb my own home in Dublin?
Yes, within the 90-night whole-home cap (unlimited if you’re homesharing a room). Track your 90 nights cumulatively across all platforms and calendar year; register the unit with Fáilte Ireland by 31 December 2026; declare the income (Rent-a-Room relief does not apply to guest income). At €150/night the 90-night ceiling grosses ~€13,500 a year — treat it as flexible side income, not an investment return.
Can I buy a second property in Dublin to run as an Airbnb?
Not legally without change-of-use planning permission, which Dublin City Council is effectively not granting to new applicants in high-demand areas, and which the new National Planning Statement restricts in cities over 20,000. Buying a second home “for Airbnb” in 2026 without secured permission means buying a compliance problem — the Fáilte Ireland register (31 Dec 2026) requires a planning-compliance declaration, and unregistered or non-compliant listings face fines and de-listing.
Do I need a Fáilte Ireland registration number?
If you let accommodation for stays of up to 21 nights at a time, yes — from 1 December 2026, with registration required by 31 December 2026. Registration is online, annual, at a nominal fee, and gives you a unique number that must appear on every listing and advertisement. Platforms may only list registered units and must remove unregistered ones on Fáilte Ireland’s order.
What happens if I don’t register or don’t have planning permission?
From the register’s go-live, expect: your listing suspended or removed by the platform; a Fixed Payment Notice (fine) or legal action from Fáilte Ireland; local-authority enforcement under the Planning and Development Act 2000 where permission is missing; and — because platforms auto-report earnings to Revenue under DAC7 — a growing chance that undeclared income surfaces in a Revenue query. The historic “nobody checks” era of Dublin short lets ends on 31 December 2026.
How is Airbnb income taxed in Ireland, and do I need to register for VAT?
Airbnb profit is taxed at your marginal income tax rate (up to the 52% top marginal rate of income tax, USC and PRSI) and must be declared. Revenue treats short-let income as not rental income — typically trading income where services are provided — and Rent-a-Room relief does not cover guest income. VAT is the structural difference: long-term residential rent is VAT-exempt, while short-stay accommodation is chargeable at 13.5%, and registration becomes mandatory once your turnover passes €42,500 in a rolling 12 months (the services threshold since 1 January 2025). A serious year-round operator will usually cross that line; a 90-night PPR host will not.
Do the new 2% rent-cap rules apply to Airbnb?
No. The national lower-of-CPI-or-2% rent cap, in force since 1 March 2026, governs long-term residential tenancies — and short-term guests are not tenants. The cap matters to this comparison in two indirect ways: it makes long-term rental income predictable (capped ~2% growth, market reset at turnover), and the predictability is exactly why more landlords are weighing short-term letting at all.
What are the best areas in Dublin for Airbnb?
The proven short-let micro-markets are the tourist core: D2 (Temple Bar, Trinity, Grafton), D1 (O’Connell Street, Docklands/IFSC) and D8 (Liberties, around the Guinness Quarter and St James’s Gate developments), where peak-season revenue of €2,500–€4,500/month has been recorded. For long-term letting, the highest registered-rent yields sit in D1 (~10.2%), D8 (~9.2%), D10 (~8.7%) and D11 (~8.4%) — see the full district rental yields table.
Is a corporate or mid-term let (1–6 months) a good middle ground?
For many owners, yes. Lets above 21 nights fall outside the short-term letting register, corporate/academic tenants pay a furnished premium (€1,900–€2,800/month for a one/two-bed), and turnovers drop from ten a month to a handful a year — while the September–June academic calendar and the year-round corporate calendar smooth out tourist seasonality. Keep written fixed-term agreements with professional advice, register with the RTB where a let qualifies as a tenancy, and remember that once a tenancy runs past six months, Part 4 security of tenure attaches.
Bottom line: choose the strategy your property is legally allowed to run
Strip the headline revenue gap down and the 2026 verdict is calm: a compliant, well-run short-term let in Dublin’s tourist core out-earns a long-term let by roughly €150–€300 a month after tax — and costs you that difference in fees, cleaning, seasonality, platform dependence and regulatory exposure. The Airbnb revenue premium is real, but it is narrower than the gross figures suggest, it only survives self-management, and it is only available to properties the planning rules let you run year-round — your own home for 90 nights, or a second property with a change-of-use permission Dublin is no longer granting. Meanwhile the Fáilte Ireland register deadline of 31 December 2026 is converting a historically under-enforced market into a data-led one overnight.
- Homeowner who wants flexible income from their own home? Homeshare (unlimited) or whole-home up to the 90-night cap; register by 31 December 2026; treat it as side income, not a strategy.
- Buying a second property for maximum income? The realistic legal route in 2026 is the mid-term corporate/academic let — most of the premium, none of the STL register, few turnovers. If you must run tourist lets, buy only where change-of-use permission already exists or can genuinely be obtained — and assume it cannot.
- Buy-to-let investor who wants rent, not a job? Long-term let, in the high-yield inner-city districts, under the 2% cap — the buy-to-let reality check has the full net-yield maths and the district yields table has the areas.
