Understanding Your Property Tax Bill

Interim Tax Bills are issued in January and are based on 50% of the previous year’s annualized taxes. Instalments are due at the end of February and April.

Final Tax Bills are mailed in May and are based on new tax rates set by council, and updated annual assessments provided by the Municipal Property Assessment Corporation (MPAC). Due dates are the end of June and September.

  • The Province decides how much must be raised for education through property taxes
  • Durham Regional Council decides how much must be raised to pay for the services it provides
  • Ajax Council decides how much is needed to pay for local municipal services
  • A series of tax rates are set for various types of property (residential, commercial, etc.)
  • The tax rate is applied to the current year’s assessed value of the property to calculate the final tax bill
  • 33% to the Town of Ajax to pay for all local municipal services such as road maintenance, parks, recreation and culture, libraries, fire, planning, etc;
  • 55% to the Region of Durham to pay for regional services such as police, ambulance, recycling, road maintenance, waste collection, transit, etc;
  • 12% to the Province of Ontario specifically for education.

The region and province each set their own budgets, while Ajax council sets the local municipal budget. The totals are combined to calculate your tax bill.

The 2026 Operating Budget forms the spending needs for the Town of Ajax.

  • Planning and Development – 2%
  • Library – 8%
  • Recreation and Culture – 16%
  • Fire and Emergency Services – 23%
  • Corporate – 26%
  • Operations and Environmental Services – 25%

Yes. The Final Tax Bill issued each year in May is your receipt for Income Tax Purposes. This Tax Bill must be stamped “Paid” by our office in order to claim for income taxes.

Schedule 2 on the back of your Final Tax Bill explains the change in your taxes from last year to this year. The Local Municipal Levy Change is the increase for the services the Town will continue to provide. Upper Tier Municipal Levy Change is due to the Region of Durham budget increase. Tax Change Due to Reassessment is based on whether your property value increased or decreased more than the average property in Ajax.

The Assessment Act allows a municipality to issue a supplementary tax bill for new buildings, new homes, alterations, improvements or class changes. Supplementary assessments can be added for the current year and up to two previous years.

Supplementary bills will be payable in two instalments only; therefore new owners are advised to plan in advance for the eventual payment of these taxes.

Tax Rates and User Fees

Tax Rates

The tax rate is calculated using the total amount of funds required for the Town of Ajax to provide goods and services, and the total assessed value of all properties within the Town.

A separate tax rate is set for each property class by each of the three government agencies (Town, Regional and Provincial).

The tax rate is set after Town Council and the Region of Durham approve their budgets and the Province of Ontario sets the education rate. The tax rate is applied to the property’s current year assessment value to determine the amount of property taxes to be billed for the year.

Property Tax Calculator

This property tax calculator provides an estimate of your annual taxes and is rounded to the nearest dollar. It may not match, nor does it replace, your actual tax bill.

The tax calculator is based on the assessed value of your property as provided by the Municipal Property Assessment  Corporation (MPAC). For newly built homes, where you do not yet have a full assessment value from MPAC, you can estimate your taxes by entering the purchase price of the property.

For Commercial and Industrial properties, this estimate does not include vacant or excess land subclasses, local charges, capping or clawback amounts. This calculator is only valid for estimating base taxes before any additional charges or credits

Stormwater Management Fee

As noted on your Final Tax Bill under “Special Charges/Credits”, the stormwater fee for residential properties is charged as an annual flat rate per residential unit. Non-residential properties will be charged based on actual imperviousness of a property.

For more information, contact the Town’s Stormwater Team at 905-619-2529, ext. 3100 or stormwater@ajax.ca

Change of Ownership and Newly Constructed Homes

Change of Ownership

An Ownership Change Tax Information letter is mailed when there is any change in title on a property.

Newly Constructed Homes

Newly constructed homes are not fully assessed. Your tax bill is based on the assessed value of the land only. Your house will be assessed by the Municipal Property Assessment Corporation at a later date.

Estimate your annual taxes by multiplying your purchase price by the current tax rate. Planning ahead for this amount ensures that when the supplementary tax bill arrives, you will have the necessary funds set aside, minimizing any financial strain.

Supplementary assessments can be added for the current year and up to two preceding years and will be payable on two installment dates when possible.
