Bankruptcy rates in the US nearly doubled between 1994 and 2004, prompting the government to pass new bankruptcy laws. The Bankruptcy Abuse Prevention and Consumer Protection Act of 2004 made it harder to file for Chapter 7 bankruptcy and imposed stricter rules for Chapter 13 bankruptcy. Major changes under the new law include requiring debtors to have filed tax returns for the past four years and making it more difficult to discharge certain debts. Chapter 13 bankruptcy allows debtors to keep some assets by proving limited debt and income, establishing a repayment plan within 3-5 years. Both Chapter 7 and 13 bankruptcies still require repayment of certain non-dischargeable debts like taxes, student loans, and child support.
