Tax revenue generated from soccer betting is expected to reach $1.8 billion in the next financial year, 20 per cent more than the government's original estimate. The government revised its forecast after reviewing turnover since legalised soccer betting was launched on August 1 last year. In July, the Jockey Club said it expected total profits of about $3 billion a year, with half of that going to betting duty. In the next financial year, officials estimate total betting duty to amount to about $12.55 billion, which is understood to include an estimated $1.8 billion from soccer betting, with the rest from the Mark Six lottery and horse racing. Chung Kim-wah, an assistant professor with Hong Kong Polytechnic University's department of applied social sciences, said he believed the government adjusted its estimate in light of the introduction of more soccer-betting options and the upcoming European Championship. While the Jockey Club said it would only announce soccer betting turnover after the first year of operations, Professor Chung said transparency needed to be increased in the long term as soccer betting was not only a business, but a policy to combat illegal betting.
