Frequently asked questions

Can I make property assessment changes outside of the Customer Review Period?

Changes to your property assessment can only be made during the Customer Review Period which ends at the same time as the final date to file a complaint. However, although the final date to file a complaint on your assessment may have passed, there are still opportunities for you to review your property details online and understand how we arrived at the valuation.

We have helpful tools and resources online. We encourage you to review your property details and check and compare your property characteristics with other properties for equity.

You can review your property value for fairness and equity on Assessment Search. You may also contact us letting us know about the inaccuracies. In doing this you can help ensure that your next property assessment is more accurate. 

Can I appeal my taxes?

You cannot appeal your taxes. The Customer Review Period shown on your assessment notice is your opportunity to review the market value of your property. You may also file a complaint on your assessment with the Assessment Review Board if you believe the value is incorrect or other information on your assessment notice is not accurate.

Why wasn’t my last year’s complaint value applied this year?

The assessment complaint process resets annually. If you disagree with your current assessment, you must file a new complaint.

  • Annual assessment: Your assessment is an estimate of your property’s market value as of July 1 of the previous year.
  • New market data: Each year, we use new market information to assess your property, making each year’s assessment unique.
  • Past decisions: Past decisions by the Assessment Review Board were based on the market information available at that time. These decisions do not apply to future assessments. 

Do I have to pay my taxes if I have filed an Assessment Review Board complaint?

Yes. It’s important to pay your property tax by the due date, even if you file a complaint.

If you qualify for a property tax refund because of a decision, here’s what to expect:

  • The City will credit any overpayment to your tax account.
  • If you want a refund instead of a credit, please send us a request.
  • Refunds over $25 are issued by cheque, while smaller credits will remain in your account.

I have filed an Assessment Review Board complaint and how I sold my property. What will happen?

If you sell your property while a complaint is in progress, the new owner will receive any tax refunds that result from the complaint decision.

To have these refunds sent to you instead:

1. Create a refund agreement with the new owner. The new owner will need to complete one of the following actions:

2. Send a copy of the agreement to The City of Calgary.

3. Ensure The City receives the agreement before the Assessment Review Board makes their decision.
