Our freind went to the tax office to pay her 2010 car tax which was around 230lt. She was stunned to receive a bill for 342 tl. It turned out that this amount was made up of 230 car tax a 52 tl penalty & 62 tl interest/fine for late payment. Apparently the offence was committed in 2007 but the trafic police had only just given the info to the tax office. Our freind had never been told she had a fine to pay but still had to pay the fine & the interest before she could pay her car tax. when we spoke to Turkish freinds about this they said this is normal & you just have to pay. the lady in the tax office said it can take upto 3 years for the police to send them charges & they just have to be paid along with the late payment costs! It seems crazy that you have to pay a late payment fee for something that you were not told about in the first place & that they cant tell you what the penalty was for.
