Here is a reply from a Fethiye Solicitor;
This road tax is illegal as a tax, but the council can ask this money like duty or any other name.. The point is, they ask this money for the roads and the job to make a new road is theirs already. They are getting council tax for it, and any other tax and duty you are paying.
so, if you like we can take this issue to the court when they send you a letter asking the money to be paid. The court will decide whether you have to pay or how much you have to pay. (most likely the court will favour you)
However to go to court you need a lawyer, to prepare the documents for you and to act on behalf of you, and the legal fee will be more than the tax, and you can not recover this legal fee even if you win the case.
What happens if you do not pay? They say you pay now you only pay 3/4 of it, and to pay this road tax you have have 2 years, you can pay in instalments. If you do not pay, it will wait, however when you go there to pay the council tax, they will ask you about road tax as well. So, you can just leave it and if they do not abolish this road tax you can pay whenever you like + some interest on it. Please note that, when you sell the property you will have to pay all the tax because they do not give you the necessary paper if you do not pay all the tax owed to the council.
