I remembered this debate about the 18% Swedish tax being on net or gross profit.
Had another look and :
"You have to pay gambling tax on the
proceeds for each taxation period, i.e.
the difference between all stakes you have received and the total payouts you have made over the period. "
That clears it in the most official way. It is a
18% tax on gross revenue like every other country.
A totally unreasonable and completely harmful taxation for the players.
Of course by now VS has lowered the RTP for all countries ..........
