thank you trainer,
however to clarify questions for people i contacted Mr Ibrahim the accountant. First of all he says he made it clear that his comments was solely regarding tax registration, not registration of short term rentals.
than he enlightened us on the subject who can stay or not stay in your property. There is a law passed in 1974 confirmes what he says, only your first degree relatives can stay in your place if you are not there. This law again based on the common term "No such thing as free bed". Again, this is a law that has been in power since 1974, nothing new, and it is ONLY related to taxation, not short term rentals.
therefore again we asked to a senior tax inspector and he answered:
"Technically what Mr Ibrahim says is correct. However, in Turkey the applications of laws are managed by 2 ways:
1) Written orders by higher authorities
2) Established customs
There is no established custom of a tax officer to walk in your "Residential House" and check if people are your relatives or not. Technically they can, however this is not applied. But please read carefully: "Once you rent your property more than once a year and only once you make an advertisement let it be verbal, on social media or on online sales sites, than your property is a business and your income is business income" Than your property is not residential anymore and any government authority can knock on your door, and will.
Hope to be help clarify.
best Wishes,
Volkan
