When you receive your property tax bill, you'll see the term "assessed value." This figure is crucial for determining your property tax amount; however, many owners do not fully understand it.
What Is Assessed Value?
Assessed value is the value assigned to your property by your local government's tax assessor to calculate property taxes. It is the basis for determining your annual property tax bill.
This valuation is typically conducted by your county or municipal tax assessor's office. The assessed value may be equal to the market value of your property. Still, in many jurisdictions, it represents only a percentage of the market value based on assessment ratios established by local law.
For example, if your property has a market value of $300,000 and your county assesses properties at 80% of market value, your assessed value would be $240,000.
Assessed Value Differs From Market Value and Appraised Value
It's important to distinguish between three related but distinct property values:
Market value:
The estimated price a property would sell for in a competitive market between a willing buyer and seller, with neither under pressure to act. Market value reflects current real estate conditions and is influenced by factors like comparable sales, property condition, location, and market trends.
Appraised value:
A professional appraiser's opinion of a property's value, which may be conducted for various purposes, including mortgage lending, insurance, or buying/selling decisions. This value represents what a property would sell for within a reasonable timeframe, assuming both buyer and seller are acting to maximize their interests.
Assessed value:
The value determined by the local government specifically for property tax purposes. It takes into account exemptions and other deductions. This value often differs from both market and appraised values due to:
Assessment ratios (a percentage of market value)
Valuation methods specific to tax purposes
Assessment timing (values may not reflect the most current market conditions)
Local assessment practices and policies
For example, your home might have a market value of $350,000, an appraised value of $345,000 for mortgage purposes, but an assessed value of only $280,000 for property tax calculations.
How Assessed Value Is Calculated
Tax assessors use several methods to determine assessed value:
Sales comparison approach: Assessors look at recent sales of similar properties in your area to establish a baseline value. They compare factors such as square footage, number of bedrooms and bathrooms, lot size, age, and location.
Cost approach: This method calculates what it would cost to replace your property with one of similar utility minus depreciation. It adds the estimated land value to the estimated cost of constructing a similar building.
Income approach: Primarily used for commercial or rental properties, this approach evaluates the potential income the property could generate, taking into account factors such as rental income, operating expenses, and capitalization rates.
After determining the property's value using one or more of these methods, the assessor applies the assessment ratio established by local law. This ratio varies by jurisdiction and property type.
Some areas are assessed at 100% of value, while others might be assessed at lower percentages.
Assessment Cycles and Reassessments
Properties aren't assessed annually in every jurisdiction. Assessment cycles vary widely. States like Georgia conduct full reassessments annually. Many jurisdictions use a combination approach, with some properties reassessed annually and others on longer cycles.
Between complete reassessments, many tax authorities apply adjustment factors to account for market changes. For instance, if property values in your area have increased by an average of five percent since the last assessment, your assessed value might be adjusted upward by that percentage.
Major property improvements typically trigger reassessment outside the normal cycle. Adding a new room, finishing a basement, or making significant renovations could prompt your assessor to recalculate your property's value.
Factors That Impact Assessed Value
Several factors influence how tax assessors value your property. Key property characteristics include square footage, lot size, and the number of bedrooms and bathrooms, with larger and more functional homes generally receiving higher valuations.
Property age and condition also matter. Newer or well-maintained properties typically have higher assessments. Features such as premium building materials, fireplaces, swimming pools, and outbuildings can significantly enhance value.
Location is crucial as well. Properties in highly rated school districts or near amenities, such as shopping centers and parks, tend to have higher assessments. Neighborhood desirability, including crime rates and aesthetics, also plays a role. Zoning restrictions can either enhance or limit assessed value based on potential uses.
Market conditions provide the broader context for valuations. Recent sales of comparable properties serve as benchmarks, and local economic factors — like job growth and supply-demand dynamics — help inform assessments.
Improvements to your property, such as renovations, expansions, and major system upgrades, can trigger reassessments and increase value. Understanding these factors allows you to anticipate changes to your assessed value and prepare for potential appeals if you feel your assessment is inaccurate.
How Assessed Value Affects Your Property Taxes
Your property tax bill is usually calculated using a simple formula:
Assessed value × Tax rate = Property tax amount
For example, if your property's assessed value is $250,000 and your local tax rate is 1.2%, your annual property tax would be $3,000.
The situation becomes more complex when multiple taxing authorities are involved. Most property owners pay taxes to several entities, each with its own tax rate:
County government
City or township
School district
Community college district
Hospital district
Flood control district
Special utility or service districts
Each entity calculates its portion of your tax bill by multiplying its specific tax rate by your assessed value. The total of these individual calculations becomes your complete property tax bill.
Some jurisdictions apply different assessment ratios or tax rates to various types of properties. For example, commercial properties might be assessed at a higher percentage of market value than residential properties, or vacation homes might be taxed at higher rates than primary residences.
Exemptions and Their Impact on Assessed Value
Many jurisdictions offer exemptions that reduce your property's taxable value:
Homestead exemptions reduce the assessed value of your primary residence by a fixed amount or percentage before taxes are calculated.
Age-based exemptions often freeze assessments or provide extra value reductions for people aged 65 and over.
Disability exemptions provide tax relief for disabled property owners.
Veterans' exemptions are available in many jurisdictions.
Agricultural exemptions can reduce assessments for qualifying ranches or farms based on their agricultural use rather than development potential.
Appealing Your Assessed Value
If you believe your property's assessed value is too high, you have the right to appeal:
Review your assessment notice carefully, noting key information like account number, market value, appraised value, and appeal deadline.
Gather evidence to support your case, such as:
Recent appraisals
Sales data for comparable properties
Documentation of property issues affecting value
Photos showing condition problems
Income and expense statements for investment properties
File your appeal before the deadline. Missing the deadline will almost certainly result in your appeal being rejected, regardless of its merit.
Present your case at an informal meeting or formal hearing, depending on your local procedures.
Consider professional help for complex or high-value appeals.
Successful appeals can lead to significant tax savings both now and in the future.
