It is not true, you can use Paribu and Btcturk safely without paying %18 KDV (It is for exchange's earning, not your). Furthermore, i recommend you Bitstamp to do wire transfer but you don't want to use international exchanges, i recommend Paribu or Btcturk. Ziraat Bankasi or Enpara, it doesn't matter. You can swift by using bank which you want.
it is free to deposit money from bank to btcturk but when withdrawing money from the exchange to bank they will take 3TL + VAT (%18)
