To avoid late penalties and interest charges, payments must be received by the Town of Grand Valley on or before the due date. A charge of 1.25% will be added on the first day of default and on the first day of each calendar month thereafter, as long as the taxes remain unpaid. Monthly interest charges will be imposed on any unpaid taxes from previous years. Interest rates are levied by the municipal bylaw pursuant to section 345 of the Municipal Act, 2001 c. 25.

Failure to receive a tax notice does not excuse a taxpayer from the responsibility for payment of the taxes nor relieve the assessed owner of the liability for interest charges due to late payment.
