Assessment & Taxation
Property taxes are due June 30 each year
Property Assessment Factors
The assessment and taxation process is governed by provincial legislation. Your property assessment is based on an estimate of market value from the prior year, as determined by the real estate marketplace (e.g., property sales).
Farmland, linear property, and industrial machinery and equipment are assessed using a process regulated by Alberta Municipal Affairs rather than by market value. For information on the assessment of farmland or industrial machinery and equipment, contact the MD’s Assessment & Taxation Department.

2026 Notice to Residents
2026 Combined Assessment and Tax Notice
Can I file a complaint about my assessment any time during the year?
No. There is a 60 day timeline from the mailing date for filing complaints about an assessment. The deadline date for filing a complaint is June 29, 2026.
If I file a complaint about my assessment, am I still required to pay my taxes by June 30?
Yes. June 30 is a legislated timeline and must be adhered to. All property taxes must be paid even if a decision has not been made. A decision regarding your complaint may take until December 31, depending on the situation. If your complaint is successful, any overpayments that may occur as a result of an assessment change will be refunded.
When do I have to pay my taxes?
Property taxes are due on June 30 each year. If you are mailing your tax payment to the MD, your envelope must be postmarked before midnight on June 30, 2026. If payment is not received before the due date, the following penalties will be applied:
- 6% of current taxes owing are applied on July 1 and October 1; and
- 12% is applied to the total balance owing on December 31 each year for non-payment of taxes.
How can I pay my taxes?
There are many ways to make payments:
- In Person (cash, cheque, money order, debit);
- By Mail;
- At the Bank;
- New this year: Online via “My MD” payment portal (accounts.mdlsr.ca)
- Telebanking and/or Internet banking; and
- In the after hours drop box located outside the MD office in Slave Lake.
The Municipal District also accepts monthly payments either by post-dated cheques or by direct debit from your bank account.
In person payments can be made at the MD office in Slave Lake during office hours, Monday to Friday 8:15 a.m. to 4:30 p.m. (closed over the lunch hour), or at the Smith sub-office, open Wednesdays from 8:30 a.m. to 3:00 p.m. from May 6 to June 24.
If I didn't receive my tax notice yet, am I allowed extra time to pay?
No. As a result of advertisements in the local newspapers and MD website, assessment and tax notices are deemed to have been received by the ratepayers. It is the responsibility of the ratepayer to provide the MD office with an updated mailing address or contact information.
What should I do if I haven't received my assessment and tax notice yet?
Contact the MD office in Slave Lake at (780) 849-4888 to ensure that your contact information is up-to-date on your tax account. It is the responsibility of the ratepayer to provide the MD office with an updated mailing address or contact information. MD property owners who did not receive their assessment/tax notice will not be granted extra time to pay the property tax amount owing.

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 June 29 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.
