If you own a short-term rental property in Greece and list it on Airbnb or Booking.com, the income you earn from those bookings is being reported directly to the Greek tax authority — automatically, every year, whether you know about it or not. This is the practical consequence of an EU rule called DAC7.
This article explains what DAC7 is, what it requires platforms like Airbnb and Booking.com to do, how Greece has implemented it into national law, and what it means practically for an owner with a property listed on those platforms today.
One important note before we begin: this article is informational. It explains how the framework operates in plain language. It is not legal or tax advice. Every owner’s situation is different, and the correct application of these rules to your specific circumstances should be verified with a qualified Greek accountant or tax adviser.
What a Directive Is — and Why It Matters
Before explaining DAC7 specifically, it is worth understanding what a European Union directive actually is. This distinction matters because it shapes how the rules apply in practice.
A directive is a piece of EU legislation that sets out a goal or result that all member states must achieve, but leaves each country to decide how to achieve it through their own national laws. A directive does not apply directly to citizens or businesses. It must first be transposed — written into the domestic law of each member state — before it has legal force.
This means that while DAC7 is a single EU directive, it produces twenty-seven different national laws across the EU, each shaped by the legal and administrative framework of the country that implemented it. What Greece requires of platforms and property owners may differ in specific details from what France, Italy, or Germany requires — even though all three are implementing the same underlying directive.
The practical implication for Greek property owners: the rules that apply to you are not the directive itself, but the Greek law that implements it. In Greece, that law is Law 5047/2023, adopted by the Greek Parliament on 4 September 2023.
What DAC7 Does — and What It Does Not Do
This is the most important section in this article, because the most common misunderstanding about DAC7 is a fundamental one.
“DAC7 does not impose any new tax or in any way regulate the taxation of income earned by sellers on digital platforms. It is a transparency mechanism, not a tax.”
What DAC7 does is create a reporting and information-sharing framework. Specifically, it places a legal obligation on digital platform operators — companies like Airbnb, Booking.com, Vrbo, and any other platform that facilitates property rental transactions — to collect information about the income their users earn through the platform and report that information to the relevant EU tax authority.
The rationale, stated directly by the European Commission, is that platform operators are better placed than tax authorities to collect and verify this information. Airbnb knows exactly how much each host earned from each booking. AADE, historically, did not. DAC7 changes that — not by changing the tax, but by changing the flow of information.
The consequence for property owners is significant but different from what many assume. It is not that you owe more tax than before. It is that the income you earn is now visible to AADE in a way it was not previously. If you were declaring your rental income correctly before DAC7, nothing material changes for you. If you were not, the risk of that being identified is now substantially higher.
What Platforms Are Required to Do
Collect and verify seller information. For every property owner who earns income through the platform, the operator must collect specific identifying information: name, address, date of birth, tax identification number, and the jurisdiction of tax residence.
Report income annually. Platform operators must submit a report to the tax authority of their EU member state of registration — detailing the income earned by each reportable seller through the platform — every year, by 31 January, covering the previous calendar year. The first reporting deadline under DAC7 was 31 January 2024, covering income earned in 2023.
Share that information with other member states. Through the EU’s Automatic Exchange of Information system, the data reported by platforms in one member state is shared with the tax authorities of every other member state where a reportable seller is resident. If you are a Greek resident earning income through a platform registered in Ireland — as Airbnb Europe is — that income is reported to Irish tax authorities and then passed to AADE automatically.
Notify sellers. Before submitting the report, the platform must inform you of the information it is reporting on your behalf. This is why property owners on Airbnb and Booking.com receive annual notifications about their income data — this is the platform complying with its DAC7 obligations, not a voluntary communication.
The reporting obligation covers four categories of activity: rental of immovable property, personal services, sale of goods, and rental of transport. For short-term rental property owners, the relevant category is rental of immovable property — which covers residential properties, villas, apartments, and any parking spaces associated with the rental.
The Reportable Seller Threshold
Not every transaction on every platform triggers a formal report. Under DAC7, a seller qualifies as a “reportable seller” if they exceed either of two thresholds in a calendar year: more than €2,000 in total rental income earned through the platform, or more than 30 rental transactions completed through the platform.
For any property owner running a short-term rental in Greece with any meaningful level of activity, both thresholds will typically be exceeded within the first few weeks of the summer season. The threshold is relevant for very occasional or incidental rental activity — a single booking, a one-off weekend let — not for an owner operating a property as a seasonal rental business.
How Greece Implemented DAC7 — Law 5047/2023
Greece transposed DAC7 into national law through Law 5047/2023, adopted on 4 September 2023. This law incorporates the directive’s requirements into the Greek legal framework for administrative cooperation in taxation and was developed to be consistent with Greece’s obligations as an EU member state.
The Greek implementation follows the directive closely in its core obligations — platform operators must collect seller information, conduct due diligence, and submit annual reports to AADE by 31 January of the year following the reporting period.
One important operational detail: a platform operator already reporting under DAC7 in another EU member state can be exempt from also reporting directly in Greece, provided it notifies AADE accordingly. This is why Airbnb’s reporting may reach AADE via Ireland rather than directly — but the data arrives at AADE in either case, through the EU’s automatic information exchange system.
Under the Greek implementation, AADE has the mandate and the infrastructure to cross-reference the income data received from platforms with the tax declarations submitted by property owners. That cross-referencing capability is now operational.
What This Means Practically for Greek Property Owners
Your income is visible. AADE knows the rental income you earned through each major platform for every year from 2023 onwards. This data arrives at AADE annually and automatically, regardless of whether you have provided it yourself in your tax declaration.
Your declaration must be consistent with this data. Your annual income tax declaration must reflect the rental income that has been reported on your behalf by the platforms. A material discrepancy between the two is exactly the kind of signal that triggers an audit.
DAC7 does not change what you owe. The obligation to declare rental income and pay the applicable tax rate in Greece has existed for years. DAC7 does not add to that obligation. It reinforces the enforcement mechanism around it.
The Greek short-term rental regulatory framework is separate from DAC7. The income tax rates applicable to short-term rental income in Greece — currently ranging from 15% to 45% depending on income level — are set by Greek domestic tax law, not by the directive. Similarly, the requirement to register your property with AADE and obtain an AMA (Αριθμός Μητρώου Ακινήτου) before listing on any platform is a Greek regulatory requirement that exists independently of DAC7.
What Owners Should Do
If you have been declaring your short-term rental income correctly and your property is properly registered with AADE, DAC7 changes nothing about your compliance position. The data the platforms report will be consistent with what you have already declared, and the cross-referencing process will find no discrepancy.
If you are uncertain about your compliance position — whether your declarations have been complete and accurate, whether your property registration is in order, or whether your tax treatment of rental income has been correct — now is the time to address it, with the support of a qualified Greek accountant or tax adviser.
The fact that income data is now flowing automatically to AADE is not, in itself, a cause for alarm for compliant owners. It is, however, a clear signal to any owner who has not been fully compliant that the previous environment of limited information visibility has ended. Acting to regularise a position proactively and with professional support is significantly preferable to responding to an AADE inquiry after the fact.
Conclusion
DAC7 is a transparency mechanism, not a tax. It changes the information available to tax authorities, not the tax rules themselves. For the property owner who has been operating correctly — registered, declaring income, paying the applicable tax — it is largely irrelevant in practical terms.
For the wider market, it is significant. It represents the end of the era in which rental income earned through digital platforms existed in a grey area of enforcement. The data infrastructure is now in place. The information is flowing. AADE has access to the rental income of every owner on every major platform, automatically, every year.
Operating correctly in this environment is not complex. It requires registration, accurate income declaration, and professional accounting support. NOMAS coordinates accounting services for the properties we manage and ensures that the financial records we maintain are accurate, complete, and consistent with what the platforms are reporting on your behalf.
