Greece launches major tax crackdown on Airbnb hosts over undeclared income
Greek tax authorities are intensifying scrutiny of short-term rental income, launching a large-scale enforcement campaign targeting property owners operating through platforms such as Airbnb and similar digital marketplaces.
The Independent Authority for Public Revenue (AADE) has begun opening thousands of tax files after electronic cross-checks revealed major discrepancies between declared rental income and actual earnings recorded by online platforms.
According to officials, the first wave of automated audits uncovered widespread mismatches involving income from short-term rentals between 2020 and 2023.
Greek Tax Authority Using Platform Data to Detect Hidden Income
Under the new enforcement framework, digital rental platforms submit financial data directly to Greek tax authorities twice annually, allowing auditors to compare platform-generated revenue with taxpayers’ official declarations.
The findings have already triggered thousands of electronic notifications through the myAADE platform, warning taxpayers about inconsistencies linked to undeclared or underreported Airbnb income.
The notices reportedly include:
- Revenue figures reported by rental platforms
- Declared income submitted to tax authorities
- Detailed discrepancies identified through electronic matching systems
Affected property owners are now being asked either to:
- Accept the findings and submit amended tax returns, or
- Challenge the data by providing supporting documentation
- Corrections Required for Tax Forms and Income Declarations
Taxpayers under review must update both:
- E2 property income forms
- Annual income tax declarations
The goal is to fully align tax filings with financial data transmitted by short-term rental platforms.
Greek authorities are placing particular emphasis on tax year 2020 cases because the statute of limitations for audits expires at the end of 2026.
Key Compliance Deadlines Announced
The AADE has established the following deadlines:
June 15, 2026 → Deadline for correcting 2020 tax year discrepancies
July 30, 2026 → Deadline for amendments covering 2021–2023 tax years
After amended returns are filed, authorities will issue revised tax assessments that may include:
- Additional income taxes
- Late-payment interest charges
- Penalties for inaccurate declarations
However, officials say voluntary compliance before the completion of a formal audit can reduce fines by up to 50%.
Not All Discrepancies May Indicate Tax Evasion
Market sources and accounting professionals caution that some inconsistencies may stem from technical or accounting issues rather than deliberate tax concealment.
Potential causes reportedly include:
- Cancelled bookings that generated no payment
- Duplicate entries
- Platform commission deductions
- Incorrect data transfers to tax authorities
Accounting firms across Greece are now reviewing platform data against previously submitted rental declarations to determine whether corrections or formal objections should be filed.
Full Tax Audits Await Non-Compliant Property Owners
Authorities warn that taxpayers who ignore the notices risk triggering comprehensive tax investigations.
Such audits could result in:
- Larger tax assessments
- Increased interest charges
- Heavier administrative fines
The crackdown reflects Greece’s broader effort to tighten oversight of the rapidly expanding short-term rental market, which has transformed housing dynamics in cities such as Athens and popular tourist destinations across the country.
As European governments continue introducing stricter regulations for vacation rental platforms, Greece is signaling a tougher stance on tax compliance within the booming Airbnb economy.
