Property Tax Rates Across Montgomery County, Maryland
Local government entities set property tax rates, which can differ significantly within a state. Annually, each county calculates its required budget to provide essential services and divides that by the total value of all taxable property within its jurisdiction. This calculation determines the property tax rate. While votes and laws are involved in setting tax rates and budgets, this is essentially the annual process.
In Montgomery County, Maryland, the effective property tax rate is 1.11%, which is above the national median of 1.02%. This means homeowners in Montgomery County may pay a higher percentage of their property's assessed value in taxes compared to the average U.S. homeowner.

The Montgomery County Department of Assessments and Taxation estimates the market value for tax purposes. The assessed value is the market value minus any applicable exemptions or limits determined by local laws and offerings. The tax assessed value is the figure used to calculate your property taxes or the amount multiplied by your tax rate to get your tax bill.

Property Tax Appeals in Maryland
In Montgomery County, homeowners have the opportunity to appeal their property tax assessments if they believe their property's assessed value is inaccurate. The process begins with a formal appeal to the Montgomery County Board of Appeals. Homeowners must provide evidence that supports their claim, such as recent sales data of comparable properties, an independent appraisal, or evidence of discrepancies in the property record. Once the appeal is submitted, the board reviews the evidence and may schedule a hearing where the homeowner can present their case in person.
The board considers the evidence and may decide to adjust the assessed value of the property, which can lead to a reduction in the property tax bill. Alternatively, the board may uphold the original assessment if they find the evidence insufficient. The outcome of the appeal can significantly affect the homeowner's financial obligations, making it a crucial process for those who feel their property is over-assessed.
Ownwell assists homeowners throughout the appeal process by providing expert guidance and support. Our team of experienced professionals helps gather the necessary evidence, prepares a compelling case, and represents the homeowner during the appeal hearing if needed. With our expertise, homeowners can navigate the complexities of the appeal process with confidence, increasing their chances of a successful outcome. By partnering with Ownwell, homeowners can ensure that their property tax assessments are fair and accurate, potentially leading to substantial savings on their tax bill.
Exemptions in Maryland
Montgomery County offers several property tax exemption programs designed to help homeowners reduce their tax burden. The Homestead Tax Credit is one of the primary exemptions available, aimed at homeowners who use their property as their primary residence. This exemption limits the increase in taxable assessments each year, providing significant relief to eligible homeowners. To qualify, homeowners must apply for the credit and ensure their property is registered as their primary residence.
Another important exemption is the Senior Property Tax Credit, which assists homeowners aged 65 and older. Eligible seniors can receive a credit based on their income and the assessed value of their home, easing the financial strain of property taxes during retirement. Additionally, veterans and their surviving spouses may benefit from the Disabled Veterans Exemption, which provides substantial tax relief to those who qualify due to service-related disabilities.
Homeowners can apply for these exemptions by submitting the necessary documentation to the county's tax office. Navigating the application process can be complex, but Ownwell is here to help. Our team of experts can guide homeowners through each step, ensuring they take full advantage of the exemptions available to them.
