Property Taxes | Municipality of Thames Centre

The Municipality of Thames Centre Tax Department is responsible for the billing and collection of all interim, final and supplementary property tax billings from residential and non-residential properties.

Your property tax bill is made up of three main components:

This tax rate is set by the Municipality to cover the cost of supplying municipal services as determined through the annual budget process. Revenues from provincial grants, user fees and other sources are deducted from the total expenditures, resulting in a final amount that needs to be raised through taxation.

A portion of the tax bill for all residents of Middlesex County goes back to the County to support their role in supplying various services including Ontario Works, Social Housing, Library and Cultural Services and Land Ambulance.

This tax rate is set by the Province of Ontario and remitted to your preferred local school board. To change your school board support, contact Municipal Property Assessment Corporation (MPAC).

Property Taxes Due Dates

Thames Centre issues two property tax bills each year: an interim bill in February and a final bill in August, with four payment installments due on:

February 28 and May 30 (interim)
August 29 and October 30 (final)

The interim bill is estimated at 50% of your previous year's taxes, while the final bill reflects the current year’s taxes, minus the interim amount.

Paying Property Taxes

Thames Centre offers a wide variety of payment methods for our residents! Check out our Paying Property Taxes page for more information!

Tax Rates

Thames Centre calculates your tax bill by multiplying your property assessment value by the tax rate, and adding your garbage cart fee. If you don't agree with the value of your property assessment, contact MPAC at 1-866-296-6722 or visit MPAC online.

2025 TAX RATES

Supplemental and Omitted Tax Bills

The Municipal Property Assessment Corporation (MPAC) provides the Municipality supplementary and omitted assessments for the current year and the past two years. You might receive a Property Assessment Change Notice if your property's assessed value or classification changes due to improvements or a change in use. These assessments are billed in addition to the regular billing cycle and issued throughout the year.

New Build/Improvement to Property

If you have built a new home and your property is not yet assessed, you can contact MPAC at 1-866-296-6722 to obtain comparable assessments in your area. Remember, property taxes are calculated by taking the assessed value of the property and multiplying it by the tax rate.

Once MPAC assesses your new home, you will receive a Property Assessment Change Notice from them. You will then receive a Supplemental property tax bill from the Municipality which will be back-dated to your date of occupancy.

Please visit MPAC's website which has some helpful information regarding New Built Home Property Assessments.

Tax Adjustment

If the status of your property changes due to fire, demolition, or otherwise, please inform us in writing by completing a Form 357/358, so the necessary adjustments to the assessed value and/or tax class can be processed.

Application Under Section 357

A property owner may make application under Section 357 of the Municipal Act for a refund of property taxes for the following reasons:

Ceased to be liable to be taxed at rate it is taxed
Became exempt
Fire/Demolition
Mobile unit removed

The property tax refund application can be made for a period during the year or for the entire year. This application must be made to the Municipality no later than February 28 of the year following the taxation year to which the application relates.

Application Under Section 358 Gross or Manifest Clerical Error

A property owner may make application under Section 358 for one or both of the two years preceding the year in which application is made for an overcharge caused by a gross or manifest error in the preparation of the assessment roll that is clerical or factual in nature but not an error in judgement in assessing the property.

This application must be made to the Municipality of Thames Centre between March 1 and December 31 of a year. A separate application is required per year.
