Ten years ago you could photograph a spare flat in Koukaki, upload it to Airbnb and take your first booking the same week. Nobody checked anything. That Greece is gone. The country now runs one of the more tightly organised short-term rental regimes in Europe: a registry number for every listing, a safety law with genuine teeth, a licence freeze in the centre of Athens, and an EU regulation arriving in May 2026 that will strip unregistered listings off every major platform at once.
Here's the part that matters if you're thinking of buying: the market itself is fine. Greek tourism keeps setting records, island occupancy in July and August still embarrasses most of the Mediterranean, and a legal, insured, registered rental earns roughly what it did before, minus a fixed layer of paperwork costs. The rules mostly punish people who wanted to wing it.
This guide walks through what the law actually requires in 2026, what compliance costs, where the restrictions bite hardest and when you're better off signing a twelve-month lease instead.
The AMA number: no registration, no listing
Every property offered for short-term rental in Greece needs an AMA, a registry number issued through the online systems of AADE, the Greek tax authority. You register per property, not per host, and the number must appear on every listing you publish: Airbnb, Booking.com, Vrbo, your own website, all of them. An advert without a visible AMA is illegal on its face, and inspectors don't need to visit the flat to spot it. They just need to read the listing.
Registration itself is the easy part. It's done electronically, it hangs off your Greek tax number, and a local accountant will typically handle it for a modest fee alongside your annual filings. Where owners trip up is what registration commits them to. Every stay must be declared in the AADE short-term rental register. The platforms report your gross income to the tax office on their own, so the two datasets get compared, and a mismatch between what Airbnb reported and what you declared is one of the most common ways hosts earn themselves an audit.
Foreign owners need a Greek tax number (AFM) before any of this can happen. If you bought the property through a lawyer, you already have one; it's required for the purchase itself.
Law 5170/2025: the quality and safety bar
Registration used to be the whole game. Since Law 5170/2025 took effect, it's only the entry ticket. The law sets minimum standards that every registered short-term rental has to meet, and it finally gave inspectors something concrete to check beyond the number on the listing.
The core requirements look like this:
- Civil liability insurance covering guests, issued by an insurer licensed to operate in Greece
- Fire extinguishers and smoke detectors, installed and working, not sitting in a cupboard still in their packaging
- A safety certificate for the electrical installation, signed off by a licensed electrician
- Pest-control certification from a certified provider
- A space that qualifies as a proper dwelling, with natural light and ventilation; basements and storage rooms dressed up as studios don't pass
- An emergency information sheet for guests, covering exits and emergency numbers
None of this is exotic. It's roughly what a small guesthouse always had to do, scaled down to an apartment. For a property built or renovated in the last couple of decades, meeting the standard is mostly a matter of booking two technicians and one insurance broker. Older island houses can need real work, usually on the electrical side, and that's worth pricing into any purchase where the wiring predates your accountant.
The insurance is the item foreign owners most often get wrong, because the policy has to come from a Greek-licensed insurer. The household policy on your home in Munich or Manchester doesn't count, however generous its liability cover reads.
Inspections and fines
Enforcement stopped being theoretical. Inspectors visit, and the fines escalate by design: painful the first time, several times worse on a repeat offence, and severe enough at the top end to wipe out more than a season of rental income. Operating with no AMA at all sits in the harshest category. The logic is transparent. Greece doesn't want to ban short lets; it wants non-compliance to be obviously bad business.
A useful mental model: full compliance costs a few hundred euros a year plus some one-off certificates. Getting caught without it can cost more than a two-bedroom Athens flat grosses in a year. There's no version of the maths where skipping the paperwork wins.
The Athens freeze, and why Thessaloniki is worth watching
In the dense central districts of Athens, the neighbourhoods that absorbed most of the city's Airbnb boom, the government has frozen new AMA registrations. A property there that doesn't already hold a number can't get one while the freeze lasts. The reasoning is the same as in Barcelona or Lisbon: entire buildings had converted to keybox hotels while locals hunted for flats, and the city centre was hollowing out street by street.
Existing registrations keep working, which produces an interesting side effect. Flats inside the frozen zones that come with a live AMA attached now trade at a premium, because the licence itself became the scarce asset. A seller advertising "with active short-term rental registration" in central Athens is telling you something about price before you've seen the kitchen.
Two conclusions for buyers. First, never assume a central-Athens flat can be short-let. Check which district it sits in, whether a registration already exists, and whether it survives the sale; get your lawyer to confirm all three in writing. Second, keep an eye on Thessaloniki. The pressures that produced the Athens freeze exist there too, and nobody in the Greek market would be surprised if similar limits followed. Buying in the centre of Greece's second city purely for Airbnb income means betting the rules stay still. They haven't been lately.
Outside these zones, on the islands, along the coast and across most of the country, registrations remain open and the nationwide standard described above is the whole rulebook.
A couple of flats or a business? Mind the threshold
Greek law draws a line between an individual quietly letting a property or two and someone running what is effectively an accommodation business. On the small-scale side of the line, you declare rental income as an individual and life stays relatively simple. Past it, the state treats the activity as professional: business registration, VAT, per-night levies and the bookkeeping obligations that come with all of it.
Where exactly the line falls has shifted over the years and depends partly on how many properties you let and how the operation is structured, so treat it as a question for your accountant before you scale, not after. The pattern to remember is simple enough. One or two properties, simple regime. Build a portfolio, and Greece expects you to look like the hotelier you've become. Plenty of foreign owners have discovered the distinction retroactively, and retroactive VAT is nobody's favourite letter to receive.
How the income is taxed
For individuals under the simple regime, short-term rental income is taxed at progressive rates: gentle on the first slice, climbing as the annual total grows. Greece also charges guests a small per-night climate resilience fee, higher in the summer months, which the host collects and passes on. You declare the income annually, and since the platforms have already reported your gross to AADE, your figures need to match theirs.
Most buyers' home countries have double taxation treaties with Greece, so the same income won't be taxed twice in full, but you will file in Greece regardless of where you live. An accountant who handles short-term rentals runs the whole cycle, typically for a few hundred euros a year. Given what they save you in mismatches and missed deadlines, it's the least optional line in the budget.
One more habit worth forming from day one: keep every invoice. Certificates, insurance, cleaning, repairs, accountant's fees. Some of it reduces your taxable base, and all of it answers questions if AADE ever asks any.
May 2026: compliance stops being optional
Until now, enforcement depended on Greek authorities finding you. From May 2026, the EU's short-term rental regulation changes the mechanics entirely. Platforms operating in the EU must collect registration numbers, verify them against official registries, and remove listings that fail the check. Booking data flows from platforms to authorities on a standard schedule, across every member state at once.
Read that from the perspective of an unregistered host. There's no knock on the door. The listing simply disappears from Airbnb and Booking.com in the same week, along with the review history and the booking calendar that took years to build. The grey zone that made casual non-compliance survivable is being closed at the platform level, and Greece, which already has its registry running through AADE, is one of the countries where the switch can be flipped cleanly. If you're buying with short lets in mind, the only sane plan in 2026 is full registration from day one.
Golden visa buyers: your property can't be an Airbnb
One rule catches investors off guard often enough to deserve its own section. Properties bought under Greece's golden visa programme, under the rules in force since 2024, can't be used for short-term rentals. The prohibition is written into the programme itself: breach it and you're risking substantial fines and the residence permit along with them. The golden visa is a residence product now, not a yield product, and Greek authorities have been explicit that they mean it.
If you want both a Greek residence permit and Airbnb income, the workable structure involves separate properties: one bought to qualify for the visa, another, purchased outside the programme, doing the earning. And if residency doesn't matter to you, none of this applies. An ordinary purchase carries no short-let restriction beyond everything described above. We've mapped the regions and thresholds in our guide to where to buy property in Greece, which pairs usefully with this one.
Where short lets still work well
Strip away the headlines and the map stays mostly green. The Athens freeze covers a handful of central districts in one city. Everywhere else, the model that made Greek short lets attractive in the first place still runs: strong summers, shoulder seasons that lengthen a little every year, and purchase prices well below comparable coastline in Spain, Portugal or the south of France.
The islands with real seasons do the heavy lifting. Crete, Rhodes and Corfu offer twenty-plus bookable weeks and airports with year-round connections. The busier Cyclades compress astonishing nightly rates into a shorter window. Coastal Peloponnese and Halkidiki trade peak-season intensity for much cheaper entry and a growing domestic market. Even Athens outside the frozen zones works, with the particular advantage of city demand in February, when the islands sleep. Browse the Greek listings on HomeNSearch and you'll see the spread: the same money buys a studio in the wrong postcode or a two-bedroom village house with a sea view and an open registration zone around it.
The maths of compliant hosting
So what does the rulebook actually cost? For a typical apartment: liability insurance runs to a few hundred euros a year. The electrical certificate and pest-control paperwork are one-offs or periodic renewals in the low hundreds. Detectors and extinguishers are a trivial one-time purchase. Add the accountant and you get a fixed compliance layer somewhere under a thousand euros a year once the certificates are in place.
Set that against revenue and the picture sorts itself by geography. A well-located two-bedroom near a Cretan beach town can gross in the mid tens of thousands across a long season, so compliance eats a low single-digit share of takings. Cleaning, management and platform commissions were always the bigger line items anyway. On a short-season island with fourteen bookable weeks, the same fixed costs bite noticeably harder, and a marginal property can slide from "decent yield" to "expensive hobby" once every certificate is paid for. Regulation didn't ruin the model; it raised the stakes on season length.
Before you buy anything on the strength of a listing agent's projections, run the numbers with every cost included. Our piece on how rental yields actually work walks through the method, including the costs that glossy projections quietly ignore.
The fallback: long lets
Sometimes the answer is to skip the whole apparatus. A twelve-month tenancy needs no AMA, no guest liability policy, no per-night fee, and it's untouched by the Athens freeze. Gross income is lower, often a third to a half below a well-run short let in a strong location, but so are the costs, the voids and the workload. Greece has also been offering tax incentives to owners who move properties from short-term to long-term letting, which narrows the gap further, particularly in Athens where tenant demand is deep and constant.
For a flat inside the frozen districts with no transferable AMA, long-let isn't the fallback; it's the plan. Everywhere else, it's the honest benchmark. A short-term rental that only beats a long lease when you ignore twelve weeks of winter voids isn't beating it at all.
Compliance checklist before your first booking
- Get your Greek tax number (AFM), if the purchase didn't already give you one.
- Confirm the property sits outside a frozen registration zone, or that an existing AMA validly transfers with the sale.
- Register the property through AADE and obtain the AMA.
- Buy civil liability insurance from a Greek-licensed insurer.
- Install smoke detectors and fire extinguishers; commission the electrical safety certificate and pest-control certification.
- Prepare the guest emergency sheet with exits and contact numbers.
- Display the AMA on every listing, on every platform, before taking a single booking.
- Hire an accountant; declare each stay in the AADE register and collect the climate fee.
- Diarise the renewals: insurance annually, certificates on their own cycles.
Do all of that and May 2026 is a non-event for you. Skip half of it and the same date becomes a deadline.
FAQ
Do I need an AMA number for a single room, or only for whole properties?
Any accommodation offered for short-term rental through a platform needs its own registration, and the number has to be visible on the listing. The obligation attaches to the advertised space, not to how much of the building you happen to own.
Can I still get a short-term rental licence in central Athens?
Not in the frozen districts while the restriction lasts. Existing registrations there continue to operate, which is exactly why central flats with a live AMA now command a premium. Outside those zones, including most of Athens and the rest of the country, registration remains open.
What happens in May 2026 if my listing has no valid number?
The EU regulation obliges platforms to verify registration numbers and remove listings that fail the check. In practice a non-compliant listing should expect delisting rather than a warning letter, on top of whatever fines Greek authorities levy for operating unregistered.
Can I short-let a property bought through the golden visa?
Not if you bought under the rules in force since 2024. Short-term letting of those properties is prohibited, and a breach risks both significant fines and the residence permit itself. Properties bought outside the programme carry no such restriction.
