A private benefactor will pay off Wakefield Wildcats' outstanding tax bill if the club gets planning permission for a new ground.
The club is currently the subject of a winding up petition by Her Majesty's Revenue and Customs.
Wildcats managing director Diane Maskill said the benefactor had asked to remain anonymous.
Wakefield Council's planning committee will decide whether to give the stadium proposal outline permission on Friday.
Maskill said: "Friday 22 October is a crucial date in the club's future both in terms of planning for the new stadium and for the very generous offer we have received from a private benefactor who has asked to remain anonymous.
"We place our thanks on record to this very kind and generous person and hope that with a positive outcome from the planning hearing we can look to a bright future for everyone who supports the club, with a new stadium on the horizon and the threat of the HMRC petition being removed."
Wakefield players are expected to attend Friday's planning meeting.
Wildcats head coach John Kear said: "This will be a momentous day in the club's history.
"The players will be in attendance as their future is in the hands of the planning committee.
"We have seen the plans for the new stadium and everyone is excited by the development, we can't wait to see the dream turn into reality for this great club."
Last month HMRC agreed to delay a winding-up hearing on the club which disputed the amount of tax owed.
A similar order was staved off in November last year after Wakefield reduced the bill from £353,000 to £194,000.
