I posted this on a different topic some time ago:
If you rent out your villa or apartment on a long term lease or tenancy agreement you're unaffected at this time.
If you rent out a room or rooms then you are affected.
If you rent out your villa or apartment on short term holiday lets, i.e. for a week or two, then you are affected.
It would appear that you need to obtain ID from each renter and submit this to the Polis. You also must inform the taxman but I don't know if this is meant to be every time you rent, or in your tax return - which of course you all do anyway
The actual logistics of how this is done I suspect will vary from region to region. This has been passed under the state of emergency laws and the fines (I have been told) are hefty if you don't comply.
I've had it confirmed to me that this new regulation covers ALL rentals made out with a regular tenancy agreement, i.e. those made through holiday letting web sites, AirBNB etc. It also covers rentals where no fee is paid.
Landlords MUST establish a system where they can connect to the authorities computer system to allow the authorities to check, in real time, who is living at a property.
For not connecting to the authorities system, the fine is 10,000tl and for failing to provide real time data, the fine is 5,000tl.
The landlords system must be in place by mid January 2017.
