Mississauga Property Tax Arrears - Pay and Avoid Tax Sale

Taxation and Finance Ontario 4 Minutes Read · published February 11, 2026 Flag of Ontario

In Mississauga, Ontario, unpaid property taxes can lead to municipal collection actions and ultimately a tax sale if arrears are not remedied. This guide explains how the City handles delinquent property tax accounts, practical steps to pay or arrange alternative resolution, and where to find the official rules and contacts to avoid a tax sale.

How overdue property taxes work

The City charges property taxes annually; unpaid balances become arrears and may be subject to collection in line with municipal procedures. Owners should check their account status promptly and use available payment methods or arrangements to prevent escalation.

Payment options and timeline

Mississauga accepts multiple payment methods and schedules for taxes; contact the City early to confirm deadlines and to request a payment arrangement where available. Many owners resolve arrears by paying the outstanding balance plus any added interest or administration charges.

Contact the City as soon as you know you cannot pay to discuss options.

Steps to avoid tax sale

  • Pay outstanding taxes in full as soon as possible.
  • Apply for any available deferral, relief, or cancellation programs the City offers and provide required documentation.
  • Contact Taxation & Revenue to set up a payment arrangement or confirm payment options.

Penalties & Enforcement

Municipal enforcement for unpaid property taxes in Mississauga is administered by the City's Taxation and Revenue division and collection processes are governed by provincial legislation. Specific collection steps, notices, and timelines are set out by the City and provincial law; owners should review official City guidance and the Municipal Act for legal authority and procedural details.
