Denmark’s licensed online gambling operators looking to take wagers on local horse races must now pay a hefty premium for the privilege.

On January 1, Denmark’s Spillemyndigheden regulatory agency officially authorized its online and land-based gambling licensees to begin taking wagers on animal-based races, be they horse, dog or pigeon. Oh, and it also okayed online bingo, which we’re assuming wasn’t a reference to the dog from that B-I-N-G-O song.

On Wednesday, the regulator reminded its licensees that bets on Danish horse races are taxed differently than other events. While most products involve a tax on operators’ betting revenue, operators must pay a ‘special contribution’ amounting to 8% of horse wagering turnover.

The new rules apply to races at Danish tracks, but not to Danish horses racing abroad. Should a punter combine a Danish horseracing wager with other racing bets, “the special contribution of the players entire contribution must be paid,” regardless of where the other races take place.
