Tax billing and account changes

Interim bills

Interim bills cover taxes due for the first six months of a year, paid in two instalments. Bills are mailed out in February with payments due in March and May.

Amounts are estimated based on 50 percent of the previous year's property taxes.

Final bills cover taxes due for the last six months of a year, paid in two instalments. Bills are mailed out in June, with payments due in July and September.

Final bills are calculated using the current year's assessment and tax rate, less your interim bill.

Supplementary and omitted tax bills are issued throughout the year to owners of newly built or significantly altered properties.

To determine what property 'change events' may trigger new tax bills, visit the the Municipal Property Assessment Corporation (MPAC) website.

Billing process 

1. You will receive a Property Assessment Change Notice from MPAC with the supplementary and/or omitted assessment value.
2. A supplementary/omitted tax bill(s) will be issued by the city. The effective dates on the bill could be from date of occupancy or date of purchase.
3. Bills are calculated by multiplying the supplementary and/or omitted assessment value by the tax rate for the applicable tax year.
4. If you own a new property, the first regular tax bill you receive from the city may only be for the portion relating to land value. You should expect a supplementary and/or omitted bill for the structure to follow.

It is your responsibility to ensure that the City of Waterloo tax office has up to date mailing information.

Paying your bill

If your mortgage payment includes taxes, please forward the supplementary bill to your mortgage company.

If you are currently enrolled for pre-authorized payments, supplementary and/or omitted tax bills will not be paid from your financial institution account. Payment for supplementary bills may be made by online or mobile banking, by mail, or in person and must be received by the due date.

If you receive supplementary/omitted tax bills and you did not own the home during this time, please forward the bills to your lawyer to arrange for payment.

Pre-authorized payments

Using this plan we automatically withdraw scheduled tax payments from your bank account. The deadline to apply for a current tax year is September 15. Full details are on the pre-authorized tax billing application form.
