There has been no football in England since early March and at League One and League Two level in particular, no games means no cash coming in as many clubs budget for the matchday income of tickets, refreshments and club shop sales.
Swindon Town chairman Lee Power fears "30-40%" of League One and Two clubs may not make it to the start of next season without further financial aid.
League Two sides, many struggling with the financial effects of coronavirus, opted to end the campaign early.
"Unless there's some help from higher up the food chain, there's going to be a number of clubs that won't see the start of [next] season," Power said.
Speaking to BBC Radio Wiltshire, he continued: "As owner and chairman, you have to start looking at how you budget and work towards what looks like a September start and how you're going to get there.
"A number of CEOs and owners of football clubs in Leagues One and Two have had these discussions and it's a simple fact that 30-40% of us won't get there unless there's some help."
