If your payment is late, the City will add a 1% penalty to the unpaid amount of your instalment. Each month that your payment is late, the City will charge an interest fee of 1.25% on the outstanding amount. This charge will be added on the first day of each month for as long as your taxes stay unpaid.

Penalty and interest charges are set by City of Markham by-laws, which are enforced by the Municipal Act, 2001. City of Markham Council and staff do not have the authority to waive or alter penalty and interest charges.
