How to calculate property tax: A step-by-step guide for property tax managers

Calculating property tax might seem daunting for businesses, but with the right tools and an understanding of the fundamentals, it can become a more manageable task. 

Property tax compliance isn’t just about numbers — it’s about understanding the intricacies of valuations and regulations that differ across jurisdictions. In this step-by-step guide, we’ll discuss what aspects require calculation and how valuations can be subjective. You’ll also learn key steps to get you started on calculating property taxes with confidence.

    What aspects of property tax compliance require calculation?

    For any business, property tax compliance requires calculating several core components that together determine the tax liability. These components include:

    Assessed value of property

    The cornerstone of calculating property tax is determining the assessed value of the property. This is typically done by a government assessor who evaluates the market value of your property, accounting for factors like land, buildings, and improvements. The assessed value can vary significantly based on each jurisdiction’s rules and the nature of the property.

    Assessment ratio

    The assessed value may not represent the full market value of the property. Some jurisdictions apply an assessment ratio, which is a percentage of the property’s fair market value. This helps determine the taxable value, which is used to calculate the amount of property tax due.

    Tax rate (mill rate)

    The property tax rate, often referred to as the mill rate, is another critical factor in calculating property taxes. The mill rate is generally determined by local authorities and reflects the amount of tax owed per $1,000 of assessed property value. Different taxing entities, such as school districts, fire departments, and local governments, may impose different mill rates.

    Special levies or additional taxes

    Some properties are subject to additional taxes or special levies, such as those for improvements or specific services. Special assessment taxes are used to fund local infrastructure projects, and their calculation may require additional effort depending on how they are structured in your jurisdiction.

    Exemptions and deductions

    Exemptions, deductions, and abatements can also affect the final property tax liability. Common exemptions may include those for non-profit organizations, historical properties, or homesteads. Understanding which exemptions apply to your business is an essential aspect of compliance.

    In what ways is property tax valuation subjective?

    While property taxes are rooted in numerical calculations, the valuation process often involves subjective elements. Understanding these nuances can help property tax managers navigate challenges when calculating taxes or evaluating assessments:

    Market value discrepancies

    Market value — the estimated amount for which a property would sell on the open market — is inherently subjective. Local assessors use sales data, market trends, and comparable properties to arrive at a value. However, individual assessors may weigh these factors differently, which can lead to discrepancies in valuation.

    Depreciation and improvements

    Determining depreciation and improvements also involves subjective judgment. Assessors consider the condition of a property, also with its age and maintenance, to evaluate depreciation, along with any improvements or renovations that may have added value. Different assessors might apply different standards for these factors, which contributes to variance in assessed values.

    Appeals and negotiations

    Taxpayers have the right to appeal property tax assessments they deem unfair, leading to a negotiation process that further underscores the subjectivity of valuation. During appeals, presenting evidence such as comparable sales or recent appraisals can influence the assessor’s decision, potentially resulting in a revised, lower assessed value.

    Steps to calculate property tax for new property tax managers

    If you’re new to property tax compliance, getting started can feel overwhelming. However, a structured approach will make the calculation process easier and ensure that nothing is overlooked. Here are key steps to guide you:

    Step 1: Determine the assessed value

    The assessed value of your property is typically provided by the local assessor’s office, and it represents a portion of the market value. It’s essential to confirm the accuracy of this value by reviewing the assessor’s report and, if needed, researching recent sales of comparable properties.

    Step 2: Apply the assessment ratio

    If the jurisdiction uses an assessment ratio, multiply the market value by this ratio to determine the taxable value. The assessment ratio will vary by jurisdiction, so it’s important to be familiar with local regulations. For example, if the market value is $500,000 and the assessment ratio is 60%, the taxable value would be $300,000.

    Step 3: Identify the relevant tax rate

    The next step is to identify the tax rate that applies to your property. Tax rates are typically expressed as a mill rate (e.g., 10 mills = $10 per $1,000 of assessed value). You can find the applicable tax rate by contacting your local tax authority or visiting their website.

    Step 4: Calculate the property tax

    Once you have the taxable value and the mill rate, you can calculate the property tax. For instance, if the taxable value is $300,000 and the mill rate is 10, the property tax would be calculated as follows:

    Property tax = (taxable value / 1,000) x mill rate
    Property tax = ($300,000 / 1,000) x 10 = $3,000

    Step 5: Account for exemptions and special assessments

    Determine whether any exemptions, deductions, or abatements apply to the property. These could significantly reduce your property tax liability. For instance, a homestead exemption may reduce the taxable value by a set amount, ultimately decreasing the property tax.

    Additionally, be sure to factor in any special assessments or levies. This could include taxes for local improvements, such as road maintenance or street lighting.

    Step 6: Review notices of assessment and file appeals (if necessary)

    Once you receive your notice of assessment, review it carefully for accuracy. This document will provide the assessed value and the calculation of your property tax liability. If you believe the assessment is incorrect, you have the right to appeal. Make sure to gather supporting documentation, such as comparable sales or a recent appraisal, and submit your appeal before the deadline.

    Why accuracy in property tax compliance is important

    Accurate property tax calculations are crucial for several reasons:

    • Avoiding penalties: Inaccurate property tax calculations can lead to underpayment, which may result in penalties and interest. Compliance ensures your business remains in good standing with tax authorities.
    • Cost savings: Overvaluations can lead to overpayment of taxes. Ensuring accurate valuations and understanding available exemptions can result in significant cost savings.
    • Informed budgeting: Understanding your property tax obligations allows for better financial planning and budgeting, particularly for businesses that own multiple properties across different jurisdictions.

    Key takeaways for property tax managers

    Calculating property tax may involve numerous components, from understanding assessed value and applying the correct assessment ratio to factoring in applicable exemptions. While valuation processes can be subjective, staying informed and involved throughout the assessment process will help ensure accuracy. Understanding jurisdiction requirements and best practices for reviewing assessments and filing appeals is vital to maintaining compliance.

    If you’re new to property tax compliance, start by understanding your local jurisdiction’s valuation procedures and familiarizing yourself with applicable tax rates, assessment ratios, and exemptions. By following these steps and keeping accurate records, you can navigate the complex world of property tax compliance with confidence.

    Property tax calculation FAQs

    What is the difference between market value and assessed value?

    The market value is the estimated price a property would sell for on the open market, whereas the assessed value is a portion of the market value that is used to determine property taxes.

    How do I know if I qualify for property tax exemptions?

    Qualification for exemptions depends on your jurisdiction and the type of property. You can contact your local assessor’s office or visit their website for specific information.

    Can property tax assessments be challenged?

    Yes, property tax assessments can be appealed if you believe the valuation is incorrect. You will need to present supporting evidence, such as recent sales of similar properties or an independent appraisal.

    Why do property tax rates vary by location?

    Property tax rates vary because they are set by local government entities to fund services such as schools, public safety, and infrastructure. Different jurisdictions have different needs and budgets, which affects the rates they set.
