Filing a Complaint with the Assessment Review Board
If you do not agree with the assessment and wish to file a complaint with the Assessment Review Board, you must submit a complaint form (and the associated appeal fee) prior to July 8 of the assessment year to the Clerk of the Assessment Review Board, P.O. Box 722, Slave Lake, Alberta T0G 2A0.
An Assessment Review Board has no jurisdiction to deal with complaints about assessments for linear or designated industrial properties. Complaints about linear and designated industrial properties must be directed to the Municipal Government Board within time period shown on the assessment notices.
Sections 311 and 337 of the Municipal Government Act stipulate that all assessed persons are deemed to have received their assessment and tax notices as a result of this publication. Your taxes must be paid by the due date of June 30 even though you may have appealed your assessment. If your complaint is successful, any overpayment will be refunded or applied to any balances owing to the MD.
Tax Due Date
The due date for payment of your property taxes in the MD is June 30 of each year. If payment is not received by the due date, penalties will be applied.
Penalties of 6% of current taxes owing are applied on July 2; followed by 6% on October 1; and then 12% is applied to the total balance owing on January 1 each year for non-payment of taxes. Failure to receive a tax notice is not a reason for non-payment of taxes. The postmark will determine the date of payment.
Avoid Late Payment Penalties
Failure to receive a tax notice is not a valid reason for non-payment of taxes. The postmark of a mailed-in tax payment will determine its official payment date.
