Property taxes are an essential source of revenue for municipalities, funding various public services and infrastructure. However, many homeowners are unaware of how their property tax is calculated and how changes in property values can impact their tax obligations. In this article, we will delve into the intricacies of property tax assessment and explain the relationship between property values and property taxes.

Understanding Property Tax Calculation

Property taxes are based on the assessed value of a home, which is determined by the municipality’s assessor. Contrary to popular belief, an increase in a home’s value does not necessarily lead to higher property taxes. To comprehend this concept better, let’s consider a hypothetical town with three homes, each with a distinct value.

The town has a total cost of providing services, let’s say $1,200 annually, which is funded through property taxes. Each homeowner pays taxes based on the assessed value of their respective homes. To calculate the tax rate, the total cost of services is divided by the total assessed property value. This tax rate is then applied uniformly to all the houses to generate sufficient revenue for the town’s services.

Impact of Changing Property Values

Every four years, the assessed value of homes is reassessed to reflect changes in the real estate market. Now, let’s assume all three properties experience an equal increase in value during the reassessment. While the total cost of services remains the same, the town needs to adjust the tax rate to accommodate the higher property values. Consequently, when the new tax rate is applied to all homes, each homeowner still pays an equivalent amount to their previous taxes.

However, let’s fast forward four years to the next reassessment. During this period, the house on the right gains more market value compared to the other two homes. As a result, the total value of all the homes increases, necessitating the calculation of a new tax rate. With this new rate, the homeowners of the first two properties end up paying less tax than the homeowner of the house on the right, since it was reassessed at a higher value.

The key takeaway from this scenario is that property taxes are based on individual home values, meaning taxes for each property can potentially increase or decrease based on the assessments of other homes in the area.

Impact of Increased Cost of Services

So far, we have discussed how changing property values affect property taxes. But what happens when the cost of providing services in a municipality increases? In such situations, the local government may opt to raise the tax rate to collect more property taxes and cover the growing expenses.

To calculate the new tax rate, the municipality determines the additional amount required and divides it by the total assessed property values. The resulting rate is then applied to all the homes, ensuring everyone contributes proportionally to fund the increased cost of services.
