Kettering Town have not made the £3,000 payment on their Company Voluntary Arrangement.
The Poppies were told at the end of September that they had fallen behind in their payments on the CVA, which the club entered during the summer to clear reported debts of £1.2m.
They club were issued with a breach notice and were told that the outstanding amount would be need to be paid by Monday this week.
Former director Gary Graham revealed on twitter that the money had not been paid and the Northamptonshire Telegraph have now seen evidence confirming the allegation.
The failure to pay the £3,000 could now see the club’s creditors approached about a new action to wind up the company.
It is the latest blow for the crisis-stricken club who saw a third successive game postponed this week due to a lack of players but, more importantly, no electricity at their Nene Park stadium after it was cut off due to unpaid bills.
Players are also still owed money with goalkeeper Laurie Walker being the latest to cancel his contract.
Majority shareholder Imraan Ladak has maintained that there are parties interested in taking over the club and it had been suggested that one of those parties could even take control of the club this week.
The Poppies are next due to be in Southern League action on October 27 when they play St Neots Town at Nene Park.
Caretaker-manager Alan Doyle has organised a friendly with Rothwell Corinthians on Thursday this week to run the rule over some trialists.
