Property Assessment

Property assessment is a value placed on a property for municipal and provincial taxation purposes. The City of Calgary assesses each property annually to distribute fair and equitable taxation. The estimated value of each property comes from the measurement, analysis and interpretation of the real estate market and is governed by the Municipal Government Act. This process is based on mass appraisal models that are an expression of how supply and demand factors interact in the real estate market.

How properties are assessed 

Your annual property assessment reflects the estimated market value (the amount it likely would have sold for on the open market) of your property based on the valuation date of July 1 of the previous year, as set by the Municipal Government Act. Real estate market conditions may change from the valuation date to when you receive your current assessment. Market changes that have occurred since July 1 of the previous year will be reflected on the following year’s assessment. Following the assessment notice mailing, there is a 60-day Customer Review Period  in which you are able to contact us with any questions you have.

To determine market value, we use one of three approaches to value:

  • Sales comparison: comparing to sales of similar properties
  • Income: capitalize the income being generated by the property
  • Cost: land value, plus the depreciated replacement cost of the improvement


Most residential properties in Calgary are assessed using the sales comparison approach. Multi-residential properties are assessed using the income approach and non-residential properties may use any one of the three approaches. Some property types, such as farm land, are subject to standards other than market value.

Types of property assessments 

Other property assessment

Property assessment notices

There are four types of property assessment notices a property owner may receive throughout the assessment/taxation year.

Annual property assessment notice 

  • Mailed to every property owner early in January each year.
  • Provides the assessed value of the property(s) on which property taxes will be based.

Amended property assessment notice

An amended property assessment notice is sent to property owners if there was a factual correction, omission or mis-description for the property on the assessment roll. If the amended property assessment notice results in a change to your property taxes, it will be reflected on your property tax account.

Supplementary property assessment notice

If your property, or an improvement to your property, was only partially complete as of December 31 of the year prior to the assessment, your annual assessment notice would reflect the land value plus the portion of the building that is complete. If the building/improvement is completed in the current assessed year, a supplementary assessment notice will be issued reflecting the number of months the building has been completed or occupied during the calendar year.

Amended supplementary property assessment notice

An amended supplementary property assessment notice is sent to property owners if there was a factual correction or omission on the supplementary property assessment notice previously issued. A tax notice will be sent separately from the amended supplementary assessment notice.

What to do if you don’t agree with your assessment

If you don’t think your assessed value is an accurate reflection of what your property would have sold for on July 1 of the previous year, contact us during the Customer Review Period. The Customer Review Period is held for 60 days following the mailing of the assessment notices each January.

Changes to your property assessment will only be considered if an inquiry is received during the Customer Review Period.

If, after speaking with an assessor, you are still not satisfied, you may file a formal complaint with the Assessment Review Board and have them review your assessment. This can only be done during the Customer Review Period.

How property assessment relates to taxes

Budget, property base and tax rate

Council decides what budget The City needs in the coming year. Then, using the total city-wide assessed property base, Council sets the tax rate to bring in only the funds it needs from property tax.

Tax rate = City budgetary needs ÷ Total assessed value of Calgary properties
Your assessment is the market value of your property (Assessment = market value).

Your share of property tax is then calculated by applying the tax rate to your assessment.

Individual share of tax = assessment x tax rate

What your property taxes support

Your property taxes support the delivery of key City services that ensure everyone enjoys a vibrant, healthy city with great communities. Property taxes are the primary source of funding for The City’s operating budget.

City services include:

  • transportation and transit
  • police and fire protection
  • land use planning and policy
  • recreation
  • waste removal
  • parks maintenance

Approximately 40 per cent of all residential property taxes collected by The City are sent to the Government of Alberta to meet provincial government budgetary requirements. For more information please visit property tax.
