MPAC issues supplementary/omitted assessments to capture assessment value that has not been returned on the annual assessment roll. For example, you may receive a supplementary/omitted assessment notice if you have a newly constructed home or condominium; you have renovated or built an addition to your property; OR the tax classification of your property has changed.

An omitted assessment under Section 33 of the Assessment Act captures assessment value ''that has been in whole or in part omitted from the tax roll for the current year of for any part or all of either or both of the next two preceding years". Omitted assessments commonly provides additional assessment for new construction and MPAC has the legislative authority to go back two previous years. So, in 2015, this means that MPAC can go as far back as January 1, 2013 to add the additional assessment to Assessment Roll, if it has not already been reflected.

A supplementary assessment under Section 34 of the Assessment Act captures assessment value for the current year. Similar to the omitted assessment provision of the Assessment Act, MPAC relies on this section of the Act to provide additional assessment on the Assessment roll for new construction when it has been completed in the year, and is ready to be assessed. In addition, MPAC can provide additional assessment resulting from renovations that have occurred during the taxation year, and make changes to property classification due to such things as demolitions and changes in property use.

Residential
The supplementary/omit property tax bill you have received is calculated by multiplying the Current Value Assessment (CVA) by the residential tax rate for the applicable year. The supplementary/omit property tax bills are only sent to the current owner of property.

Commercial/Industrial/Multi-Residential
For commercial, industrial and multi-residential properties, the City recalculates, the corresponding year's tax cap adjustment as shown on your supplementary/omit tax bill.

Note:

  • The current owner is responsible for any unpaid taxes regardless of the year billed.
  • If there are arrears on your property for supplementary/omitted taxes, you can contact your solicitor to confirm whether funds were held back on closing or if the Statement of Adjustment can be re-opened with the vendor.
  • You should ask your solicitor, if title insurance was purchased on your behalf.

Payment of Supplementary & Omitted Tax Bills
Supplementary & Omitted Tax Bills cannot be paid through the Pre-Authorized Tax Payment Program or through a mortgage company — you will need to pay this through another accepted payment method or forward this bill to your mortgage company for payment.

Additional information about supplementary/omitted bills may be found on the City of Toronto website.
