Hearts have denied proceeds of the recent share offer will go towards any potential settlement with HMRC.
The club insists all the revenues raised will go towards working capital requirements and youth development rather than settling their current dispute with HMRC.
Hearts are under a transfer embargo until Christmas after failing to pay wages on time and made over 16m shares available to fans.
The club hope to raise £1.79m, with supporters taking control of 10% of the club.
Director Sergej Fedotovas told the club's website: "I stated at the weekend that the matter of the potential HMRC liability would be dealt with separately and outside of this current share issue.
"I have noted some comments that might not be the cast but I can reassure all supporters that their money will be going to the club and not to cover any potential liability in relation to this matter.
"I would also like to reiterate that we will be defending this matter and will do everything in our power to secure a positive outcome for the club.
"We are being totally transparent with supporters but it would be entirely wrong to suggest this share offer is for anything else other than what we state it is for."
