How long can your checking account be in negative balance before they close the account?

The length of time a checking account can remain in a negative balance before it is closed varies by bank and account type. Generally, banks may close accounts after 30 to 90 days of being overdrawn, but policies differ. It's important to review the specific terms and conditions of your bank, as some may charge fees or take action sooner. Contacting your bank directly can provide clarity on their specific policies.
