Government together with JCC has put a website for online payments of road tax at http://rtd.mcw.gov.cy/ (click on the icon on the right). I went all the way to credit card authorization.
Does anybody have any idea what happens after payment? In normal case, when you go to a co-op, they will put a stamp on your road tax disc. Obviously they cannot do it in this case.
If it worked, it would be very convenient as this year I didn't receive road tax discs for some reason (even though I passed MOT in December). Otherwise I have to waste a few hours in the queue in road transport dept. offices...
