The Edinburgh club had agreed an extension that would allow them further time to pay.
Hearts had been the subject of a winding-up petition last month after falling behind in payments. However, the closure threat was lifted when the club agreed a way to pay the bill in two instalments.
First-team players had agreed to defer their November salaries to help out and former players set up a fighting fund to safeguard the club's future.
Meanwhile, Hearts Youth Development Committee has thanked Tynecastle fans for their fund-raising.
They said: "HYDC are grateful that supporters, groups and Hearts have been raising monies to purchase shares and then donating them to HYDC."
