The British Horseracing Authority awaits "government's response with interest" as the question of replacing the current betting Levy system will be heard in the House of Commons on Thursday morning.
The racing industry has long called for government intervention against the current system, from which offshore online betting is exempt and costs the sport tens of millions of pounds.
Bob Blackman, Conservative MP for Harrow East, will ask John Whittingdale, the Secretary of State for Culture, Media and Sport, "w hat progress he has made on replacing the current horserace betting Levy".
Chancellor George Osborne proposed a 'Racing Right' to replace the Levy in last March's Budget.
Reports suggest a ministerial response will be made on Thursday, potentially outlining a scheme that could be in place by April 2017 which would pool together income from betting, on racing in shops and online, to give the sport a significant cash boost.
BHA media manager Robin Mounsey said: "We are aware that a parliamentary question has been lodged for discussion on Thursday morning regarding what progress has been made on replacing the current horserace betting Levy.
"We await confirmation of the government's response with interest."
BHA chief executive Nick Rust has been working hard to fill the void in the interim after having imposed an Authorised Betting Partner (ABP) policy, which requires bookmakers to pay racing an agreed chunk of the profits they make from racing bets online.
Betfair, bet365, 32Red and BetVictor have so far signed up to the new system, with the four bookmakers having agreed to make voluntary contributions from their remote activity.
Other established bookmakers like Ladbrokes, Betfred, Coral, William Hill and Paddy Power have yet to agree to ABP status.
