Typically Bankruptcies will stay reported on your Credit Report for 10 years (per Fair Credit Reporting Act (FCRA) ). However, fortunately, most of the Credit Reporting Agencies will remove then after 7 years has passed.
The credit reporting time limit is seven years for most negative information. Certain types of negative information will stay on your credit report for longer than that. Delinquency information like late credit card payments and collections can be reported for seven years from the date of the delinquency. Charge-offs, seven years + 180 days from the date reported to the credit bureau, usually this is simply seven years from the date of the charge off.
