I paid the council tax online last year using this link :
https://webportal.fethiye.bel.tr/web/guest/47You have to know your '
Sicil Numarası' ( a 6 digit number , kind of registration number ) that you could find on your previous receipts.
Once you find it and enter it on the field named 'Sicil Kodu' and click on 'Göster' , your unpaid taxes and other items are listed.
if you want to pay ( I paid by credit card ) click on '
Tüm Borçları Seç' to select all the items to be paid ....
... and then click on '
Seçili Borçları Ödemek için Lütfen Tıklayınız'
If you don't want to pay or think its risky or confusing , at least you will know what you have to pay.
P.S : Don't be confused if you have paid but still see some unpaid items. These may be the items to be paid in 2021 they already have listed. Check the dates please.
