Introduction of $2 paper billing fee for tax bills

Paper property tax bills will have a $2 fee starting in June 2026.

This fee helps cover the real costs of printing and mailing paper bills, such as paper, envelopes, and postage. It also cuts down on paper use, improves service, and is more reliable during mail disruptions.

Those who sign up for e-billing will not be charged the $2 fee.

Interim tax bills are sent in January each year and have one installment due the second last business day of February. The 2026 interim bill is due Friday, February 27, 2026. The interim bill is approximately 40% of the previous annual tax bill.

The final tax bills are usually sent out in late-June or early-July each year and have two installments, due the second last business day of July and September respectively. The 2026 final tax bill is due July 30 (first installment) and September 28 (second installment).

Please keep your final tax bill for income tax purposes. There is a $15 charge for tax statements and / or tax bill reprints.

You can pay your tax bills by the following methods:

  • Pre-authorized Payment Plan (PAPP) – complete the PAPP enrollment online or print the PAPP form to submit in-person. Equal monthly payments can be withdrawn from your account by the municipality. This option is only available if an account is up to date. 

  • Telebanking/Online Banking – through most banks – search Keyword “Mississippi Mills,” choose “Mississippi Mills (TWN) – Taxes” and use the full roll number as your account number.

    • Need help with online banking? Check out our step-by-step guide on our Paperless page.

  • In person at most banks with your tax bill.

  • By mail - payments sent by mail must be received on or before the due date.

  • Post-dated cheques – make sure to include your tax roll number on all cheques.

  • After-hours drop box at the back of the municipal office.

  • In person by cash, debit or cheque at the municipal office during regular business hours.

Tax bills are sent to the last known address provided by the owner. Fill out this form, call or send by mail. You remain responsible for payment. 

When a property is sold, the tax department needs a copy of the Registered Transfer to change the ownership on the tax roll. The Municipal Property Assessment Corporation (MPAC) also sends lists of ownership changes to the municipality bi-weekly.

Properties that have been severed or had a change to their legal description take longer to be processed by MPAC and so take longer to show on the tax roll. 

Tax Certificates are issued when payment of $60.00 for each roll is received in the office. Make cheques payable to Municipality of Mississippi Mills, 3131 Old Perth Rd, PO Box 400, Almonte, ON  K0A 1A0.
