Tax Billing Cycle

If you do not receive your tax bill, please contact the City of Windsor to discuss your tax account by phoning 311 or 519-255-CITY (2489). Please note that failure to receive a tax bill does not exempt you from paying your taxes and the applicable late payment charges.

You may also access the e-service for property owners. My Property Tax allows you to view details about your tax bills, upcoming due dates, balances and more, as well as request tax statements and advise of updates to your account online.

To get started, property owners must visit the E-Services page on the City's website, and then choose My Property Tax to set up an account.

Final Tax Bill:

Supplementary Tax Billings:

• Additions to the returned assessment roll are referred to as supplementary taxes. They are billed based on supplementary assessment rolls received from MPAC (Municipal Property Assessment Corporation). These bills incorporate both the municipal and educational purpose levies and may have up to a maximum of two instalments. Supplementary tax rolls are generally billed and mailed in the second half of the year.
• A supplementary bill would result from a new house or commercial building being constructed or an addition to assessment on an existing house or commercial building such as a new garage or addition. When a house is built, it could take the assessment office two to three years to put an assessment on it. This can result in a property owner receiving up to three bills. Depending on when a property becomes occupied, the bill will be prorated for the number of days. Please contact Municipal Property Assessment Corporation (MPAC) (phone: 1-866-296-6722) for questions regarding the assessment amount used to calculate a supplementary bill or the number of days indicated on the bill.

Local Improvement Charges:

• Annual local improvement charges are billed on the Final Tax Bill (see above). The property owner is notified of these charges and a due date is provided to pay the amount in full. After this due date passes, the charges are added to the tax account.
• Some examples of local improvements include:
  • Full Municipal Service
  • Sanitary Sewer Replacement
  • Storm Sewer
  • Encroachment
  • Weed Cutting
  • Street Lights
  • Street Pavement
  • Curbs and Gutters, etc.

Business Improvement Area (BIA) Levies:

• BIA levies are usually on the final tax bill and are charged on properties with a commercial or industrial assessment that fall within a designated area set within boundaries which are approved by the BIA association. The BIA tax rate is calculated based on the budget approved by the BIA association and the assessment value of the property.
