Business Improvement Area (BIA) Assessment

In 2011, City Council passed a Notice of Motion for the consolidation of the business and non-residential tax. The consolidation of business tax revenues into the non-residential property tax began in 2014 and concluded as of the 2019 roll. The business tax consolidation process occurred over a 5-year period with 10 percent being added to the non-residential property tax rate in 2014 and 2015 and 20 percent being added in 2016, 2017, 2018, and 2019.

Why didn’t I receive a business assessment notice?

The City consolidated the business and non-residential tax and will not be assessing businesses for business tax. The City will still collect Business Improvement Area (BIA)  tax on behalf of the BIAs so that business owners can continue to jointly raise and administer funds for various projects and promotional activities throughout the year. Your BIA tax bill will include the assessed value of your premises as well as information on the Customer Review Period and how to file a complaint. The BIA assessment is valued utilizing a typical net annual rental value applied the total square footage occupied by the business.

Each BIA receives its revenue from local business owners in the area. This revenue is collected by means of a Business Improvement Area Levy. The annual BIA tax bill is not requesting payment for municipal business tax. It is a levy for business improvement funds which The City of Calgary collects on your behalf.

In 2019, collection will continue for business tax accounts with outstanding balances from prior years, including businesses within BIAs. For more information, go to

What to do if there are changes to your business premises

If your business moves out of the BIA or closes mid-year, your business will receive a letter indicating your amended assessed value prior to receiving your Statement of Account.

It is your responsibility to advise Assessment as soon as possible if there are any changes to your business premises as those changes could impact your BIA business assessment and your BIA taxes.

  • Move to a new premise or open a new premises, and/or branches of an existing business.

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

The assessed value of your business premises is related to the amount you will pay for your BIA tax . If you don’t think your premises’ BIA assessment value is an accurate reflection of what the typical net annual rental value would have been for your premises as of July 1 of the previous year, contact Assessment during the Customer Review Period indicated on your BIA tax bill.

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