Hearts say the £450,000 tax bill due to HMRC has been paid in full.
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."
