In the US you'd have to make a profit to have the tax liability, and if that's the case, the company is unlikely to be going through a fire sale. There's a host of payroll taxes associated with employees, but those get paid as employees get their paychecks, so qualifies under "debt".
See item 1) debt holders. Within the class of debt holders, the tax man and/or employees with salary claims often have special preference amongst creditors in many countries.
