Starting in about 2011, many cities and municipalities in Tuscany (and elsewhere in Italy) introduced a "Tasso di Soggiorno", basically a per person, overnight tax for stays in vacation accommodation of all kinds. The amount of the tax depends on the type of accommodation, with the highest rate being for five star hotels and the lowest for camping grounds. The tax is also limited to a maximum number of nights in a given accommodation. This might need to be taken into consideration if you foresee having to pay a lot of tax - staying at one base and not changing your hotel or agriturismo could save money. There are also rules about issuing separate receipts for the tax which makes it cumbersome to simply incorporate the tax into the accommodation nightly or weekly rate.
As of the 1 April 2012, the municipality of Greve in Chianti started to charge this tourism tax which is applied to non-residents staying overnight during the period March through October every year.
The rate for rooms is 1 Euro per person per night, up to a maximum of 4 nights per accommodation (max. 4 Euros per person total).
The rate for apartments and houses is 1.5 Euros per person per night, up to a maximum of 7 nights per accommodation (max 10.50 Euros per person total).
The rate for hotels varies according to the number of stars and ranges from 0.5 Euros to 4 Euros per person per night.
Persons under 14 years of age are exempt from paying this local tax.
This tax is very likely NOT included in the prices of the vacation rentals listed here.
