The finance ministry is preparing to open by the end of March an electronic platform, where homeowners who rent their properties short-term, through Airbnb or otherwise, will be required by law to declare those properties for taxation purposes.

Landlords who fail to declare their short-term rental properties will face hefty fines, of up to 5,000 euros.

These short-term rentals will be taxed at the same rate as long-term apartment or house rentals: 15 percent for up to 12,000 euros, 35 percent for revenues between 12,000 and 35,000 euros, and a 45 percent tax rate for rental income of over 35,000 euros annually.

If the landlord provides additional services, such as board, those will be taxed as income from entrepreneurial activities, with a tax rate of between 22 percent and 45 percent.
