  • Escalation: repeated or continuing nonpayment leads to liens and enforced collection; exact escalation schedules are not specified on the cited pages.
  • Non-monetary sanctions: tax liens, referral to enforcement, and denial of assessment relief are possible outcomes under municipal practice.
  • Enforcer and inspections: the Department of Finance administers assessments and collections; the Tax Commission issues determinations. Use official contact pages for complaints and inspection requests.
  • Appeals and time limits: the Tax Commission provides appeal filing procedures and hearing scheduling; specific filing deadlines and appeal windows are described on the agency pages and should be checked directly.
