Purpose and definition of a tax assessment in Massachusetts

A tax assessment determines the market value of a property. This assessment forms the basis for calculating property taxes, which local governments use to fund public services and infrastructure. The assessment ensures a fair distribution of the tax burden among the property owners.

Tax assessments are conducted by local government officials called assessors. These professionals determine the value of a property using a variety of methods to ensure fairness and accuracy.

To calculate the property tax owed, the assessed value is multiplied by the local tax rate. This rate is sometimes referred to as the mill rate or kilometer rate.

This process helps ensure property owners’ tax contributions remain consistent, reflect the value of their property and ensure adequate funding of municipal services.

Methods for assessing property values

There are different methods for assessing property values, each with its own approach. You can therefore assume that a local appraiser will determine the value of the house.

  1. Market value assessment

    • Method overview: This method compares the property to similar properties that have recently sold in the same area. The appraiser reviews the sales data to determine a fair market value. It is the most common method. It’s important to note that you should not rely on online reviews as a basis for your home’s market value.
    • Factors taken into account: Key factors include location, size, condition and amenities of the property. The sales prices of comparable houses in the neighborhood are decisive for this assessment.
    • Example: If a home in the same neighborhood with similar square footage and amenities sells for $300,000, your property may be valued at that value assuming it shares common characteristics.
  2. Cost approach

    • Method overview: The cost approach estimates how much it would cost to replace the property with a similar property at current prices, taking into account depreciation.
    • Factors taken into account: This includes the value of the property, construction costs, and depreciation due to age or wear and tear.
    • Example: If a new home similar to yours costs $200,000 to build and your home has lost 10% in value, the appraised value could be $200,000 – $20,000 = $180,000 plus the property value.
  3. Income approach

    • Method overview: This method calculates the value of income-producing properties such as rental units or commercial buildings based on income potential.
    • Factors taken into account: Appraisers take rental income, occupancy and operating costs into account. The capitalization interest rate (yield) also applies.
    • Example: If a rental property generates $50,000 annually and the market cap is 8%, the value of the property could be $50,000 / 0.08 = $625,000.

All three of these methods determine how property taxes are calculated.

Examples of property tax calculations

Understanding property tax calculations helps illustrate the impact of tax assessments on the tax bill. Here you will find detailed examples of residential and commercial properties:

  • Example 1: Home ownership

    • Market value: $300,000.
    • Rating ratio: Many jurisdictions use a market value ratio to determine taxable value. In Massachusetts it is 100%.
    • Rated value: $300,000 × 1.00 = $300,000.
    • tax rate: Property tax rates are expressed as a percentage of assessed value. Here we assume a tax rate of 2%.
    • Property tax: $240,000 × 0.02 = $4,800.
    • Explanation: The homeowner would owe $4,800 in property taxes based on the assessed value of $240,000.
  • Example 2: Commercial property

    • Market value: $1,000,000.
    • Rating ratio: For commercial real estate, assume a ratio of 100%.
    • Rated value: $1,000,000 × 1.00 = $1,000,000.
    • tax rate: In this example the tax rate is 2.5%.
    • Property tax: $1,000,000 × 0.025 = $25,000.
    • Explanation: Based on the assessed value of $1,000,000, the commercial property owner would owe $25,000 in property taxes.
