Quick answer
Some obligations are excepted from discharge; tax treatment and other exceptions require detailed review.
Do now
Gather tax returns and assessments, support orders, fines, dates, and prior payment records. Ask which debts may be dischargeable, which remain payable, and how they would be treated under each chapter.
Watch for
“All taxes are erased” and “no taxes can ever be erased” are both unreliable generalizations. Domestic support has special protection; a discharge does not cancel every government obligation.
