delinquent
dih-LING-kwunt/dɪlˈɪŋkwʌnt/
Failing to meet a legal or practical obligation.
Your account is delinquent because last month's payment is still unpaid.

Etymology
With an intensifying prefix, “leave” underlies a verb meaning to fall short, neglect an obligation, or do wrong. These senses connect overdue or neglected duties with the adjective’s use for minor misconduct.
In context
Lenders often work with borrowers to help bring delinquent or defaulted accounts up to date, but significant delinquencies and defaults will affect your credit score.
