County Taxes - Tax Information


Dear Montgomery County Taxpayer:


The Fiscal Year 2025 (FY25) operating budget for the period beginning July 1 reflects our work to prudently manage the County’s fiscal bottom line while strengthening our schools, protecting public health, improving public safety, investing in the jobs of the future, and growing the County’s tax base.

Check out more details on the budget at

While there is no change in the property tax rate, property tax revenues are estimated to increase in the FY25 approved operating budget due to rising property values. The average County homeowner will see a $26 monthly increase caused by rising assessments. The budget also includes a tax credit of $692 for all owner-occupied, principal residences that have a Homestead Property Tax Credit application on file with the State Department of Assessments and Taxation.

There are multiple programs to assist homeowners with their tax obligation. The Homeowners’ Property Tax Credit Program is available to reduce taxes for those living on limited or fixed incomes. We encourage everyone living on limited or fixed incomes to apply for the Homeowners’ Property Tax Credit. The State of Maryland will determine eligibility for residents. To apply, call 1-800-944-7403 or go on the web to, click on Homeowners’ Property Tax Credit Application Form HTC (2024).

In addition to a state tax credit, households earning less than $60,000 may be eligible for the County Supplemental Homeowners’ Property Tax Credit, which, combined with a special property tax credit for eligible senior residents (65 years or older), averaged $1,214 last year and benefited over 4,002 County residents.

The Individuals 65 and Above and Retired Military Services Members Tax Credit is for residents at least 65 years of age who are either retirees from the Armed Services (or certain uniformed services), who are surviving spouses of deceased retirees from those Armed Services, or who have owned and lived in their owner-occupied homes for at least 40 years.

For more information on any of these programs or assistance, please visit or call 311.

Montgomery County is one of the best places to live, raise a family, earn a living, and grow a business. We are working together to make an outstanding county even better by investing in schools, public safety, job growth, and help for the vulnerable among us, while staying within our means.

As always, we welcome your comments and feedback.

County Property Tax – The General County tax is levied on all property in the County and funds, in part, such basic services as police protection, elementary and secondary education, the community college, transportation, health and social services, and libraries. There are additional County taxes that are levied either Countywide or in specially defined areas of the County to fund projects and programs. The following taxes are Countywide (all taxpayers pay these taxes): the Transit Tax, which funds public transportation services including the Ride On bus system, the Fire District Tax, which funds fire and rescue services, and the Advanced Land Acquisition Tax, which funds land acquisitions by the Maryland-National Capital Park and Planning Commission (M-NCPPC). Five additional taxes are levied only in specially defined areas: the Metropolitan Tax funds M-NCPPC local park facilities and parks programs and the Regional Tax funds M- NCPPC planning and administrative programs, three taxes fund recreation facilities and programs, provide additional service in urban districts, and provide infrastructure in development districts (see below). Whether a taxpayer pays one of these special area taxes depends on where the property is located. To determine which Special Area taxes apply, please refer to the Tax Rate Schedule, as described below.

State Property Tax - This tax is levied by the State of Maryland for the payment of principal and interest on State bonds.

Municipal District Property Tax - This tax is levied by each municipal area within the County. Although the services provided by tax revenues differ for each municipality, they are used generally for street and sidewalk maintenance, trash removal, tree care, sanitation, and police protection.

Development Districts and Special Taxing Districts - If you own real property in tax classes R061 (Kingsview Village Center), R064 (West Germantown), or R065 (White Flint), additional charges will appear on your real property tax bill. Through the creation of development districts and special taxing districts, the County finances certain infrastructure improvements by issuing bonds secured by taxes and assessments levied on property in the district. An ad valorem special tax is levied on all real property located in the districts to generate revenues to pay the debt service on the special obligation bonds issued for each district. In the Kingsview Village Center and West Germantown Development Districts special assessments on undeveloped (not assessed at full value) residential property will generate revenues to pay the debt service on the special obligation bonds issued for each district. Revenues collected from each development district and special taxing district are used exclusively for that district.



How the Tax Rate is Determined - The real property tax rate, which is set each year by the County Council, is an ad valorem tax, meaning it is applied to the assessed value of the property. The fully phased-in assessed value equals the full cash value of the property. The real property tax is levied annually on all taxable land and improvements.

Tax Rate Schedule - For a detailed tax rate schedule for real and personal property taxes, visit the Department of Finance at or call 311.

Assessment Information - All property in the County is subject to taxation, unless specifically exempt. Each property is assessed every three years by the State Department of Assessments and Taxation (SDAT) and certified to the County for tax billing purposes. For more details about your assessment and the appeal process, visit SDAT at or call 240-314-4510.

Tax Credit Information - The County offers many tax credits and exemptions against the real property tax for which you may be eligible. To learn more, visit us at

Homestead Property Tax Credit - To assist homeowners who are affected by large assessment increases, the State of Maryland, Montgomery County, and municipalities limit the annual taxable assessment increase to 10% for principal residential properties, except for the Town of Kensington which has a 5% limit. This limit, called the Homestead Property Tax Credit, is not applicable the first year following the purchase of a home, and therefore the taxable assessment may be higher than it was for the previous owner. Property owners are required to file an application with SDAT which administers this credit. If you wish to learn more about the program, visit SDAT at or call 866-650-8783 (toll free).

County Income Tax Offset Credit (ITOC) – State Law requires a Homestead Property Tax Credit application to be on file with SDAT to qualify for the County ITOC. The ITOC is listed as “County Property Tax Credit” on tax bills and has been $692 for each eligible property for several years. The Homestead Property Tax Credit is a one-time application which is required to be on file with SDAT by May 1, 2025 to ensure that the ITOC appears on future tax bills (bills beginning July 1, 2025). To apply for the Homestead Property Tax Credit online, go to: or for a paper application, go to

Property Tax Disclosure – Montgomery County requires that residential property owners who sell their home must estimate and disclose to the prospective buyer the property tax for the subsequent levy year. Since the buyer will not be eligible for the homestead credit in the first year following purchase of the new home, the difference between the current year’s and next year’s tax can be significant. This disclosure requirement assists the consumer when purchasing a home in the County. To obtain more information and review the online tax calculator, visit the Office of Consumer Protection at or call 240-777-3636.

Homeowners Property Tax Credit – Maryland Homeowners Property Tax Credit and Montgomery County Supplemental Homeowners’ Property Tax Credit are administered by SDAT. These tax credits are granted to eligible homeowners of all ages, with the exception that taxpayers age 70 and older may file three years retroactively. Applications must be filed by October 1st. The program provides tax credits for homeowners who qualify on the basis of their household income compared to their tax bill. State and County programs use (1) a maximum property assessment of $300,000 to compute the credit, and (2) require net worth not to exceed $200,000 excluding the value of the primary residence and qualified retirement assets. For more information or to obtain an application, visit SDAT at or call 800-944-7403.

Senior Property Tax Credit – The County offers a property tax credit for senior residents, based on 50% of the combined State and County Homeowners Property Tax Credit. This credit is available to residential property owners when one of the owners is at least 65 years of age. If you applied for the Homeowners Property Tax Credit, SDAT has the age information to determine eligibility and there is no need to apply for this credit separately. However, you must apply for the Homeowners Property Tax Credit to be considered. For specific questions about this program, call SDAT at 800-944-7403.

Individuals 65 and Above and Retired Military Services Members Tax Credit - The County offers a property tax credit for property owners aged 65 and above who either (1) have owned and lived in their home for the last 40 consecutive years, OR (2) are retired from one of the United States’ armed forces, including military reserves, the National Guard, the uniformed corps of the Public Health Service and the uniformed corps of the National Oceanic and Atmospheric Administration. For information about this tax credit, please call 311 (240-777-0311).

Fire Sprinkler System Tax Credit - The County offers a one- time real property tax credit of up to 50% of the General County real property tax to partially offset the cost of installing an approved complete automatic sprinkler system used for fire protection in any detached single-family or attached dwelling unit, or multi-family building in which a fire sprinkler system was not legally required to be installed. For more information or to obtain an application form, visit us at and click on “Taxes” then “Individual Tax Credits” or call 311.



When Taxes are Due - Payments for annual bills and the first installment of semi-annual bills must be received (postmark is not sufficient) on or before September 30th, and become delinquent on October 1st. The second semi-annual installment payment must be received on or before December 31st, and becomes delinquent January 1st. Delinquent taxes are subject to interest and penalty at the rate of 1-2/3% per month until paid in full and are calculated on the net amount of the bill, after any credits are applied. Delinquent taxes, including unpaid interest and penalty charges, are a lien on the property and are sold in accordance with all State laws during the subsequent calendar year. A tax lien sale will also occur if the original amount on the tax bill was paid, but interest and penalty remain unpaid. Accounts eligible for tax lien sale are listed for four consecutive weeks in a Montgomery County newspaper and are subject to a tax sale advertising fee. Property tax accounts taken to tax sale are subject to redemption interest and may be subject to additional costs incurred by the certificate holder.

Taxes on principal residential properties are paid on a semi- annual schedule unless a taxpayer chooses to make both payments on or before September 30th. Taxpayers who escrow their payments may elect to pay annually, but must notify their lenders by May 1st of their intent to pay annually. Taxpayers will receive a tax bill that will permit those who do not escrow their taxes to pay on either a semi-annual or annual basis. Semi-annual bills include two payment coupons, while annual bills include one coupon. Payments for partial year levies (three-quarter, half year, or one-quarter) for newly constructed properties are due 30 days after the bill is mailed.

Real property taxes on residential and commercial properties defined as “small business” are also eligible for semi-annual payment. For more information on the semi-annual program, please visit us at and click on the link for “Taxes”, then select “Reviews & Bulletins.”

How to Pay Taxes - Taxpayers have four options for paying their property tax bill:

  1. Pay online using electronic check, credit card or debit card on the County’s website at Convenience fees are charged if payment is made by credit card or debit card.
  2. Pay by telephone using an electronic check, credit card or debit card (American Express, Discover, MasterCard, and VISA) by calling 240-777-8898. Convenience fees are charged if payment is made by credit card or debit card.
  3. Pay by mail with a check payable to Montgomery County, Maryland. Include coupon and mail to Montgomery County, MD, P.O. Box 824845, Philadelphia, PA 19182-4845.
  4. Pay in person at the Division of Treasury, 27 Courthouse Square, Suite 200, Rockville, MD. Payment options: cash, check, credit card or debit card (American Express, Discover, MasterCard, and VISA). Money Orders are not accepted. Convenience fees are charged if payment is made by credit card or debit card.​

Convenience Fee - Payments by credit card or debit card, whether being made online, by phone, or in person, are assessed a convenience fee of approximately 2.3% of the payment amount. This fee is levied by the payment processing company and cannot be waived by the County. The convenience fee is non-refundable if a property tax refund is requested. Payments made by electronic check through our website and telephone service are free of charge.

Online Banking - Customers using online banking services are advised to schedule their payments to be made a minimum of five business days in advance of the due date to ensure timely delivery and avoid late fees (as such payments may be delivered by U.S. mail and not sent electronically). An alternative is the “Electronic Check” feature on the County’s website which provides true electronic payment delivery, free of charge, and an assured delivery date.

Mortgage Information - All taxpayers receive the original tax bill and are responsible for ensuring that their taxes are paid on time. The County tax bill displays in the Mortgage Information box the name of your mortgage lender if it participates in the County’s electronic data retrieval and tax payment (mass-pay) program at the time the bill is prepared. Taxpayers are encouraged to review the lender information on their tax bills. The County makes individual billing information available to mass-pay participating lenders for making escrowed payments. Property owners may wish to contact their lender to ensure that their bill will be paid. If their lender does not have the correct billing information, the property owner should forward a copy of the tax bill to the lender. Disputes arising from non-payment or late payment of escrowed taxes must be resolved between the taxpayer and their lender.

Even though taxpayers may have established an escrow account with their mortgage lender, lenders do not pay Supplemental levies for newly constructed properties and additions. Therefore, taxpayers must ensure that payment is made. We encourage you to verify that your taxes have been received by the County and whether you owe interest and penalty. You may check your account at the County’s website, call 311, or visit our office.

Change of Address - In Maryland, SDAT is the official custodian of all addresses relative to State and County taxes. If you wish to change your mailing address you must notify SDAT by visiting their website at or by calling 240-314-4510. Please note that failure to change the mailing address does not relieve the taxpayer of the obligation to pay the property tax bill.

Principal Residence or Rental Property – SDAT determines if a residential property is owner-occupied and thus qualifies as a principal residence, making it eligible for homestead credit, semi-annual payment, or homeowners tax credit (if applicable).

For that reason, SDAT reviews accounts and obtains information from several sources. One source is a County rental license that each property owner must obtain prior to offering a residential property for rent. For information on how to obtain a rental license and for additional details on this program, visit the Department of Housing and Community Affairs at or call 311.



Solid Waste Charge - All ratepayers are billed directly for County supported solid waste and recycling services, facilities and programs. The solid waste charge is made up of components which vary based on the services provided. For non-residential property owners, the charge is based on the gross floor area and/or generator category, and for multi-family dwelling owners it is based on the number of units on file. For more information, visit the Department of Environmental Protection at or call 311.

Water Quality Protection Charge - This charge funds many of the County’s clean water initiatives mandated by the State, including projects to restore eroded stream banks, upgrade stormwater ponds, control litter, clean storm drains, and install rain barrels, rain gardens and green roofs. A hardship exemption is available for homeowners and 501(c)(3) organizations, while property owners with stormwater controls may be eligible for a reduction. For more information, call 311 or visit the Department of Environmental Protection at

Bay Restoration Fund Fee – The State of Maryland levies a fee on all properties in support of a dedicated Bay Restoration Fund (BRF) used to improve the water quality of the Chesapeake Bay. Since most property owners receive water and/or sewer service from their utility company, the majority of taxpayers pay this charge on their utility bill. Those who have a septic system and do not receive water service from a public utility are levied the fee on their property tax bill. For more information on the BRF, visit the Maryland Department of the Environment at or call 410-537-3000. A financial hardship exemption for eligible homeowners is available. If you are levied the BRF fee on your tax bill and wish to determine if you meet the eligibility criteria, please visit us at or call 311.

Urban District OMD Fee - Properties that are an Optional Method Development (OMD) within an Urban District are charged a fee for maintenance of public amenities in the right-of-way. There are three Urban Districts which charge an OMD fee in Montgomery County: Bethesda, Silver Spring, and Wheaton. The term OMD is a zoning term that relates to how a property is developed. If a property meets certain requirements, the developer may request to develop under the “optional method” which allows them to apply to develop more than the standard density of the zone if the developer agrees to provide certain public amenities such as off-site improvements in the right-of-way. Urban Districts are charged with the maintenance of public amenities installed by OMDs in the public right-of-way areas. These amenities include trash and recycling receptacles, trees, turf areas, litter collection, brick sidewalks, and special landscaping beds. OMDs are assessed by the Urban District Manager for which public amenities are to be maintained by the Urban District and the number of units. Maintenance for each amenity is performed on a regular set schedule. Properties are billed for this service based on per unit costs, total units, and the frequency with which these units are serviced. Cost is calculated so only the actual cost to the Urban District to perform the service is charged to property owners. For more information, call 311 to be connected with your respective Urban District Manager.
