Generally - income tax liability is a responsibility of the owner of the sold property - and should be paid from owner's funds.
The trustee is acting under the court supervision and his/her responsibilities include to satisfy any tax debt as the first priority.
I would expect that the trustee to put aside some amount to cover your tax liability - federal and state (if any).
If you feel that is the issue - you may file a complain to the court which appointed the trustee.
If the trustee will mismanage funds and at the tax time - there will not be enough funds to cover your tax liability and there would be additional penalties - you may file a complain to the court and in also sue the trustee for damages.
But the tax liability - would be your's - not trustee's liability - that would be between you and the IRS.
Let me know if you need any help.
