Property taxes are a combination of the Township's, the United Counties of Leeds and Grenville tax ratio and the education tax rate. The tax ratios are calculated based on the value of your property.

1. Property Value.  The value of your property is determined by the Municipal Property Assessment Corporation (MPAC).  Learn how your property was assessed on MPAC's website, AboutMyProperty video.
2. Education Tax Rate.  This tax rate is set by the Province of Ontario
3. County Tax Rate.  This tax rate is set by the Counties of Leeds and Grenville and calculated for each of the property tax classes ( residential, industrial, commercial, etc.) and pay for services such as paramedics, hospitals, maintaining highways and bridges, providing services such as social assistance and childcare education, etc.
4. Municipal Tax Rate.  This tax rate is set by the Township of Leeds and the Thousand Islands and pays for services, such as fire services, library services, public works and parks maintenance, capital infrastructure and waste management.

Property owners will receive two property tax bills from the Township each year.

• The interim tax bill, mailed by mid-February is due by the third Friday in March and represents 50% of the previous year's tax bill.
• The final tax bill, mailed out by mid-August is due by the third Friday in September and is the balance of the year's taxes.

There are several methods to pay your tax bill.

Property tax payments must be received by the tax department on or before the due date to avoid late penalties.

Failure to receive a tax bill does not excuse a taxpayer from the responsibility for payment nor relieve the liability of penalty for late payment.

A penalty/interest charge of 1.25% will be charged on any unpaid amount and added on the first business day of each month thereafter until paid.

The Municipal Property Corporation (MPAC) is responsible for the classification and assessment of all properties in Ontario under the Assessment Act and regulations established by the Provincial government.

As a property owner in Ontario, you are required to support a school system, even if you do not have children or your children are not currently attending school. This information can be found on your Property Assessment Notice.

For residential properties that are occupied by tenants, the tenants school support preference will supersede that of the owners.

For properties that have more than one self-contained unit, such as a duplex, the tenants for each unit can direct their school support, as though they were assessed separately.

School support designation helps property owners and tenants identify which school board they wish to support in a school board election. School support information collected by MPAC is provided to municipalities and school boards for planning purposes.

There are five different school support designations:

• English public
• French public
• English separate (Catholic)
• French separate (Catholic)
• Protestant separate (Penetanguishene only)

As per legislation, your school support defaults to the English Public school board. However, you may be able to change your school support.

You can view and update your school support designation online via an online portal if you are a residential property owner or a tenant registered with MPAC. 

To get started, visit the portal at  School Support Designation | MPAC

Anyone may request a tax certificate if the request is submitted in writing and the appropriate fee is paid.
