The Irn-Bru First Division club now have until 5pm on Tuesday to settle a £134,000 tax bill after being hit with a winding-up order from Her Majesty's Revenue and Customs.
Majority shareholder Masterton and the Dunfermline board met non-footballing staff at East End Park on Monday morning to update them on the situation and an announcement was originally expected on Monday afternoon.
However supporters will now have to wait another day to discover the club's fate.
Former Dunfermline player and manager Jim Leishman has been fronting a steering group set up in a bid to guide the Pars through their immediate cash shortage and build a sustainable long-term ownership structure.
He told STV on Monday afternoon: "Gavin Masterton had a meeting with staff this morning and told them he would make an announcement tomorrow.
"Nothing has changed from last week. The options include administration or liquidation.
"I'm just an employee of the football club - Gavin Masterton is in charge of the club's future."
Dunfermline lost 4-3 to Dumbarton in front of 3,409 fans at East End Park on Saturday and are due to host Falkirk on Wednesday but there is no guarantee the game will go ahead.
