When you file bankruptcy, you must complete a means test. The bankruptcy means test is a form that uses your income over the past six months to determine a number of important issues, such as whether you qualify for Chapter 7, how long your Chapter 13 plan must be and how much you must pay into the Chapter 13 plan.he should wait at least 90 days before filing bankruptcy or the credit card company will try to make the debt nondischargeable. Example. Gary needs cash, so he takes cash advances from his credit card-he takes one advance of $500 and then another advance the following week of $900.
