Guelph property tax: four instalments and interest that cannot be waived
Guelph's instalments fall on the last banking business day of February, April, June and September. The interim bill arrives in February and is based on your MPAC assessed value and a portion of the previous year's tax rate. Unpaid taxes bear interest of 1.25% per month, or 15% a year, starting the day after the due date and again on the first day of each following month, and the City says it cannot waive or alter these charges. Payments go first to penalties, interest and late fees, then to the oldest outstanding taxes. You can pay on the instalment dates, join a pre-authorized plan, have your mortgage company pay, or use the City's Property Tax Portal.
