Greece Reports 973 Million Euros in Declared Short-Term Rental Income for 2025

Greece recorded 973 million euros in declared short-term rental income in 2025, according to figures presented by Giorgos Pitsilis, governor of the Independent Authority for Public Revenue (AADE). The tax authority attributed the revenue level to structured data sharing with major booking platforms and systematic digital oversight across the market.

Speaking at the 27th Prodexpo conference in Athens, Pitsilis reported that declared short-term rental income has expanded from approximately 70 million euros in an earlier period. The shift reflects administrative adjustments in how the tax authority monitors property listings, tracks host activity, and cross-references financial records against booking platform records.

What the data shows

The 973 million euros figure published by AADE represents total declared gross revenue reported by property managers and hosts across Greece for the 2025 period. According to figures presented by Pitsilis, this outcome marks a substantial increase from approximately 70 million euros recorded in an earlier period before direct digital monitoring was implemented.

A primary factor behind the increased revenue capture is the reduction in non-compliant property listings on major platforms. According to AADE, the share of short-term rental properties failing to display the mandatory registration number fell from 11 percent to 5 percent across active listings in Greece.

The data also details the impact of retrospective tax enforcement. A targeted compliance operation focusing on the 2023 tax year identified 34,000 taxpayers who had failed to declare short-term rental income. Following administrative contact and automated notifications, the tax authority recorded 37,000 voluntary compliance declarations, which yielded an additional 105 million euros in declared income for that tax year.

How it was measured

The figures were compiled by AADE through direct registry data, taxpayer declarations, and data-sharing agreements with three major online booking platforms: Airbnb, Booking, and Expedia. Under these agreements, platforms share transaction data and registry compliance figures directly with the tax authority, allowing automated cross-checks against individual tax filings.

Pitsilis presented the findings during the 27th Prodexpo conference, held October 14-15 at the Athens Conservatoire. The conference brings together real estate executives, investors, legal professionals, and government regulators to evaluate property developments and legislative framework adjustments in Greece.

Addressing a panel titled “The Digital State Myth? Eradicating Bureaucracy in Land Registries and Urban Planning,” Pitsilis stressed that the agency's strategy relies on continuous digital matching rather than manual spot audits.

“The transition from isolated inspections to a tax administration that systematically uses data is essential,” Pitsilis said. “What matters is the data, its quality and its consistency with all the information available to us.”

Platform compliance and registration monitoring

Formal cooperation between AADE and booking intermediaries has reshaped how listings operate in the Greek market. Mandatory registration numbers are required on listings hosted by Airbnb, Booking, and Expedia. Listings that omit valid registration credentials face automated flagging and removal under joint protocols established between AADE and the platforms.

The drop in unregistered listings from 11 percent to 5 percent demonstrates the operational effect of automated filtering. When listings without verified registration numbers are removed or hidden by booking channels, operators are prevented from accepting reservations off the tax grid. The remaining 5 percent gap reflects listings currently under administrative review or subject to non-compliance procedures.

Targeted audits and voluntary declarations

The enforcement campaign for the 2023 tax year illustrates the mechanics of AADE's analytical cross-matching. By matching bank account records and transaction datasets provided by Airbnb, Booking, and Expedia against submitted tax returns, the tax authority flagged 34,000 taxpayers with undeclared short-term rental revenue.

The subsequent notification campaign prompted 37,000 voluntary compliance declarations from property owners seeking to correct prior omissions before formal tax fines were assessed. That secondary filing process captured 105 million euros in previously unrecorded gross rental income.

Who this affects

For short-term rental operators and property management companies in Greece, increased tax visibility alters operational parameters. Professional managers who previously competed against unrecorded listings face a more balanced regulatory environment as unregistered operators are filtered out by major platforms.

For property owners and individual hosts, the tightening alignment between channel partner records and tax filings reduces the feasibility of underreporting earnings. Taxpayers operating without mandatory registry numbers risk direct removal from major booking distribution channels in addition to retroactive tax assessments and compliance penalties.

For institutional real estate investors evaluating Greek hospitality assets, published tax revenue figures offer clearer baseline data on short-term rental yields. Clean registry records and verified revenue declarations provide transparent metrics for underwriting acquisitions and commercial financing.

What the data does not tell you

While the 973 million euros metric confirms gross declared income, AADE's figures do not break down revenue by geographic region, island cluster, or municipal district. Consequently, the data does not disclose the concentration of rental income between high-density urban areas such as Athens and seasonal resort destinations across the Aegean or Ionian islands.

The figures also do not indicate total net earnings realized by property owners after accounting for platform distribution commissions, municipal fees, cleaning expenses, utility charges, or property maintenance costs. Furthermore, the report does not clarify the exact date range of the earlier period when declared income stood at approximately 70 million euros, preventing precise year-over-year percentage calculations.

What to watch

Property managers and short-term rental investors in Greece should track several key operational indicators over upcoming filing cycles:

• Verification status of property registration numbers displayed on active Airbnb, Booking, and Expedia listings.
• Future tax compliance initiatives targeting undeclared income from subsequent tax years beyond 2023.
• Technical integration updates between AADE digital registries and third-party property management software.
• Regulatory adjustments affecting tax rates or municipal fees applicable to multi-listing management portfolios.
