Supplementary Tax Bills

The Assessment Act allows a municipality to issue a supplementary tax bill for new buildings, new homes, alterations, improvements or class changes. 

If you’ve made additions or improvements to your home or business property, it may change the value of your properties assessment, which is determined by the Municipal Property Assessment Corporation (MPAC). The Township will issue a supplementary tax bill that will reflect the change in your property tax amount as a result of changes in your property value.

You’ll receive a supplementary tax bill if:

• Your house was recently built and when you purchased it, the property was assessed as vacant land
• A new building was constructed on your business property
• You made renovations or improvements to your property that increased its market value such as an extension or pool
• The use of all or part of your property has changed, resulting in a change to your tax class

If you own a new home, your supplementary tax bill will reflect the assessed value of your home from the occupancy date of the first owner.

Since the Township can issue a supplementary tax bill only after receiving the property assessment information from MPAC, you will receive your supplementary tax bill after the effective date of your supplementary assessment value.

Supplementary assessments can be added for the current year and up to the two preceding years.

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