A Conversation on Common Tax Issues

This section provides an overview on common issues that municipalities face with regards to property assessment and taxation. While this list could be extensive, the purpose is to satisfy the basic needs of individuals that are new to the municipal environment. If you have suggestions for other topics to be included on this page, please email AUMA Advocacy.

Municipal control over property taxes

Raising taxes routinely carries a level of political risk. Municipal elected officials face this challenge every year as the municipal property assessment base is relatively fixed and, therefore, municipalities are routinely forced to increase property taxes to cover rising costs. When considering any increase in property taxes, municipal elected officials must be cognizant that any increase they approve will also be combined with any increase that the province makes to education taxes.

To explain, a property tax bill generally consists of two taxes: a property tax set by the municipal council to fund local services in the community and a property tax set by the province to fund the K-12 education system. The municipality does not control the education tax amount but they are responsible to collect it on behalf of the province. As such, if property taxes increase, taxpayers may place the blame on their municipal council despite the fact that a portion or all of the tax increase may have been implemented by the provincial government through education taxes.

‘Tax room’ is a term that is common in the municipal sector. The term suggests there is a limited amount of room for a municipality to increase property taxes in any particular year without drawing negative political attention. The ‘tax room’ will vary depending on the local political climate but common increases may range from one to five per cent. If the province approves a large increase to education tax then a municipality may view that the province has invaded its ‘tax room’ and therefore, impacted its ability to increase property taxes as much as it would have planned.

One of the contributing factors to this issue is that municipalities must make budget decisions without knowledge of what the province plans for education taxes as each level of government operates with different budget cycle. Municipalities use the calendar year and the province uses a fiscal year-end of March 31. Therefore, municipalities tend to conduct their budget deliberations in the fall of each year and may approve their upcoming year’s spending based on a targeted percentage increase in taxes. In the spring, the province releases its budget which includes its education tax requirements. If the education tax has increased, municipalities may face the dilemma of choosing to proceed with their current budget or cut their spending to lower the combined tax increase which, in turn, causes them to reduce their planned service levels to the community.

The balance of control over property taxes and the political challenges it creates is a key factor in why AUMA members have passed several resolutions calling upon the provincial government to eliminate education property taxes. 


In fall 2015, the City of Calgary approved its 2016 interim budget based on a 4.7 per cent increase to municipal property taxes. In April 2016, the province released its 2016-17 budget which included a 10.2 per cent increase in the amount of education taxes to be collected from Calgary property owners. Recognizing the political challenge of proceeding with such a large combined increase in tax rates, City Council opted to reduce its municipal budget to a 3.5 per cent increase in property taxes. Combined, the increases in municipal and education taxes resulted in a 6.1 per cent tax increase for Calgary property owners and thereby produced a significant amount of negative media attention.

Municipal fees versus taxes

Municipal revenue is generally made up of three sources: property taxes, grants and fees. Municipalities use fees as a method to fund the cost of services that are not considered a benefit to the overall community or can be easily allocated based on the use of a service. Common examples of municipal fees may include permits to construct buildings, purchase of a cemetery plot, animal licenses, business licenses, or access to a recreation facility such as a pool.

Municipal councils can set fees at different amounts. Depending on the service, municipalities may choose to set fees at a level that is designed to recover the full cost to deliver the service. For example, a municipality may determine that the administration of new development should pay for itself and, in turn, set development permit fees at a level that will recoup the cost for the municipality to process building permits and inspect the work of each builder.

In other cases, the municipality may choose to keep a fee low so that it does not present a barrier for residents or businesses to use the service. In those cases, the overall tax base will subsidize the cost of that service. The most common example would be recreation services which are typically cost intensive but municipalities want to ensure that all residents, despite income levels, are able to use recreation programs and facilities. So while not all property owners may use the recreation services, a portion of their taxes may support the cost of that service.

Each municipality will approach the use of fees from a different perspective depending on how it wants to support or incent different individuals and organizations in the community. To understand a municipality’s fee structure, one should refer to what is commonly known as a ‘rate and fee bylaw’.

Tax stabilization

Year to year a municipality’s budget can vary in size as the cost of services change or major purchases are approved. If municipalities were to adjust tax rates upwards or downwards in response to each year’s budget, it may create confusion among taxpayers and lead to challenges in public communication and possible distrust of council.

In response, some municipalities choose to create a tax stabilization reserve as a means to add consistency to the level of taxation. The reserve represents a pool of funds or a ‘savings account’ that can be drawn upon in years when the budget would require a significant increase in taxation. The monies in a tax stabilization reserve can fund the extra expense which allows the level of taxation to remain consistent with the previous year. In years where the budget is lower than past levels of taxation, the additional tax revenue can be saved in the tax stabilization reserve for future use.

Tax stabilization practices can be an effective tool but the practice also creates risk for a municipality. If a municipality draws from a reserve instead of increasing taxes, the difference in revenue will need to be recovered at some point unless the municipality reduces its spending in the future. If spending is not reduced, the municipality will be forced to implement a significant tax increase in the future.


A municipality’s 2016 budget involved the collection of $800,000 in property taxes. In 2017, the budget has increased such that the municipality requires $880,000 in taxes; representing a 10 per cent increase in tax levels. Council is only willing to approve a 3 per cent increase in taxes, which would bring tax revenue of $824,000. In order to achieve its planned spending of $880,000, the municipality chooses to draw the difference of $56,000 from its tax stabilization reserve.

The tax impact of development

One of the key challenges of municipal taxation is that the assessment base is relatively fixed and therefore, any increase in a municipality’s costs generally requires an increase in taxation. This is why economic development is a priority for many municipalities as any new development allows for the burden of property taxes to be spread over a wider number of properties, and in turn, helps minimize the need to increase taxes on each property.

To demonstrate, assume that a municipality has an assessment base of $100 million that consists of a mix of residential and non-residential properties and two large manufacturing plants. In the upcoming year, the municipality needs to increase its tax revenue by $50,000 from $1,000,000 to $1,050,000. The average tax bill in 2016 was $2,000.

In Scenario A, one of the manufacturing plants closes and relocates its buildings. This results in a loss of $5 million in taxable assessment. The loss in assessment combined with an increase in total taxes means the average property would see a $211 increase for its 2017 tax bill.

In Scenario B, the properties remain status-quo and there is no development in the municipality. The increased level of taxation means the average property would see a $100 increase for its 2017 tax bill.

In Scenario C, twenty new houses are built, which adds $4 million in taxable assessment. The average property would only see a $19 increase for its 2017 tax bill.

    Scenario A Scenario B Scenario C


Decrease in assessment base


No change in assessment base


Increase in  assessment base

Taxes required $1,000,000 $1,050,000 $1,050,000 $1,050,000
Taxable property assessment $100,000,000 $95,000,000 $100,000,000 $104,000,000
Average annual property taxes $2,000 $2,211 $2,100 $2,019
Change in 2017 taxes for average property   $211 $100 $19


  1. Average value of each property is $200,000 and the average value of the manufacturing plant buildings is $5,000,000.
  2. One tax rate is used for all properties.

The example is a representation of the experiences of many Alberta municipalities. Small municipalities that are experiencing a loss or zero growth in their assessment bases are challenged with unsustainable growth in taxes on property owners. On the other hand, municipalities experiencing new development have the advantage of distributing any required tax increase over a larger number of properties which limits the tax increase on each property owner. For instance, a municipality that has new development can implement a zero per cent tax increase on property owners and still collect more taxes than the previous year because of the new taxable properties.

This demonstrates why development is so important to municipalities and why each municipality’s annual budgeting process will usually involve a review of any changes in the assessment base in order to understand the tax impact on property owners. Increased levels of taxation can be absorbed much more easily in municipalities with new development and can be much more politically challenging for municipalities with no development.

Changes in market values and tax rates

A common misunderstanding of municipal taxation is the assumption that when the market value of property increases, a municipality will collect more tax dollars. In reality, market values are not a factor in how much a municipality collects in taxes. Municipalities determine the amount of taxes to be collected during the budget process and if there has been any change in market values since the prior year then that change is reflected by adjusting the tax rate.

For example, if a municipality has budgeted to collect the same amount of property taxes as the previous year and property values have increased by 10 per cent, then the tax rate will be reduced by a corresponding amount so that the municipality’s total tax revenue remains the same.

While changes in market value will not impact a municipality’s tax revenue, it can impact an individual’s property tax bill. For example, if an individual property value increases by five per cent, but the average property value in the municipality increases by seven per cent, the property owner would see a lower than average tax increase. In contrast, if an individual property value increases by five per cent, but the average property value increases only two per cent, the property owner would see a higher than average tax increase.

Cost recovery of utility services

The cost to deliver water and wastewater services can often represent one of the largest expenditures for an urban municipality. Due to this high cost, a municipality’s approach to utility fees can have a significant impact on its taxation levels. For instance, some municipalities have adopted a full cost pricing model so that 100 per cent of utility costs are paid for by those users. In turn, those municipalities have the potential to offer lower property tax rates. In other cases, municipalities may choose to subsidize a portion of water and wastewater service costs through property taxes and in turn, may have to charge higher taxes.

This distinction between full and partial cost pricing of utilities is worth noting because municipalities are often compared in terms of their tax rates. However, one must consider the extent to which each municipality uses fees versus taxes to fund its expenses. This issue is more noteworthy when comparing rural and urban tax rates where rural municipalities are typically not responsible for water and wastewater services. In those comparisons, one must consider how much of the urban municipality’s taxes are used to fund utility services. 

While the cost of water is influenced by regional factors, the extent to which municipalities fund their water and wastewater services through property taxes is also a key factor in why municipal water rates in Alberta can range from less than $1 per m3 and others are over $5 per m3.

AUMA has resources on how to plan and fund municipal water and wastewater systems as part of an overall focus on water conservation. Studies have shown that households will reduce their water consumption if municipalities install metering systems and bill users based on the volume of water used. Furthermore, if municipalities use a full cost pricing model, then residents and businesses will know the true cost of water instead of hiding a portion of that cost within property taxes. That knowledge can influence usage patterns such that users and municipalities can reduce their overall costs.

Budget deficits and taxation as it applies to each level of government

One of the key differences between Alberta municipalities and the provincial and federal governments is the approach to budget deficits and taxation.

Municipal governments rely on a property-based tax system where the tax base is relatively fixed. The Municipal Government Act prohibits a municipality from approving a budget with a deficit. Therefore, as costs increase a municipality will typically need to increase its level of taxation each year unless there has been sufficient amount of new development that can be taxed instead of increasing taxes on all other property.

Alternatively, federal and provincial governments rely on an income-based tax system. As income levels rise and fall, federal and provincial governments have the ability to approve a budget with a deficit, which is a key reason why income tax rates remain relatively consistent year over year.

Tax implications of an annexation

When a municipality annexes land from another municipality, the terms of the annexation will generally include an agreement on how properties within the annexation area are to be taxed for a defined period of time. Each annexation agreement will be different but agreements generally involve a restriction on tax rates unless a landowner chooses to subdivide or rezone their property or the time limit of the agreement expires. One should refer to their local agreement for an understanding of the terms of the arrangement.
