Property owners in Bethesda, Maryland pay a combined real property tax rate of about $0.79 per $100 of assessed value before any special district charges. That total is built from the Montgomery County general rate of $0.6742 and the Maryland state rate of $0.1120 for fiscal year 2025–2026.1Maryland Department of Assessments and Taxation. 2025-2026 Tax Rates and Homestead Credit Caps Bethesda is unincorporated, so there is no separate city tax, but properties inside the Bethesda Urban District or a fire service area carry small additional line items on the bill.
How the Rate Is Built
Maryland taxes real property at three levels: state, county, and special district. The state rate of $0.1120 per $100 applies uniformly across Maryland. Montgomery County layers its $0.6742 per $100 on top for the general county tax.
Because Bethesda is a community within the county rather than an incorporated municipality, there is no fourth municipal rate. What Bethesda owners do see, depending on where the property sits, is a Bethesda Fire District charge and a Bethesda Urban District fee. The urban district fee funds streetscape maintenance, landscaping, and other services the county’s Urban District staff provides in commercial and mixed-use areas.2Montgomery County, Maryland. Urban District Fees These charges are small next to the county rate but they do vary by service zone, so the exact figure on your bill depends on your address. The county publishes updated rates each August.
Calculating What You Owe
The math is simple. Divide the assessed value by 100, then multiply by each applicable rate. For a Bethesda home assessed at $800,000:
- Base units: $800,000 ÷ 100 = 8,000
- County tax: 8,000 × $0.6742 = $5,393.60
- State tax: 8,000 × $0.1120 = $896.00
- Subtotal: $6,289.60
Fire district and urban district charges would be added to that subtotal. For a property in the Bethesda Urban District, expect a few hundred dollars more depending on the applicable rates. Montgomery County offers an online estimated tax calculator that pulls in every charge tied to a specific property account.3Montgomery County, Maryland.

How Your Assessed Value Is Set
The rate is only half the equation. The other half is the assessed value, which the Maryland State Department of Assessments and Taxation (SDAT) sets through a three-year cycle. Every property in the state is physically reviewed once every three years, with a new market value assigned based on comparable sales, land condition, and improvements.4Maryland General Assembly. Maryland Code Tax-Property 8-104 – Valuation of Real Property
When a reassessment raises your value, Maryland phases the increase in over three years: one-third in year one, two-thirds in year two, the full new value in year three.5Maryland General Assembly. Maryland Code Tax-Property 8-103 – Assessment of Real Property in General A decrease, by contrast, takes effect immediately. The phase-in softens a hot market but also means your bill can keep climbing for two more years after a single reassessment notice.
Certain changes trigger a reassessment outside the normal cycle: improvements adding at least $100,000 in value, a zoning change at the owner’s initiative, a substantial change in use or character, or a subdivision.4Maryland General Assembly. Maryland Code Tax-Property 8-104 – Valuation of Real Property A significant renovation in Bethesda can clear that $100,000 threshold easily, so build the resulting tax bump into any renovation budget.
Credits That Reduce the Bill
Several programs can meaningfully lower what you actually pay. Each has its own eligibility rules and application, so check them individually.
Homestead Tax Credit
The Homestead Tax Credit caps how much your taxable assessment can rise each year on your primary residence. Montgomery County sets that cap at 10%, and the state uses the same 10% figure.6Montgomery County, Maryland. County Homestead Tax Credit Even if your phased-in value jumps 20% in a reassessment year, the amount actually taxed only rises 10%. In a market where Bethesda values regularly outrun that limit, the savings compound across a cycle.
You must file a one-time application with SDAT to establish eligibility. The credit only applies to the home you occupy as your principal residence.7Maryland Department of Assessments and Taxation. Maryland Homestead Property Tax Credit Program Buyers who never filed after closing are often leaving money on the table.
Homeowners’ Tax Credit
This state program limits property tax based on household income. It is open to homeowners of any age, but combined gross household income cannot exceed $60,000.8Maryland OneStop. Homeowners Property Tax Credit Application Form HTC 2026 The formula taxes nothing on the first $8,000 of income, then 4% on the next $4,000, 6.5% on the next $4,000, and 9% above $16,000. If your actual bill exceeds the formula amount, the state credits the difference.9Maryland Department of Assessments and Taxation. Homeowners Property Tax Credit Program Net worth cannot exceed $200,000, excluding qualified retirement savings and the home itself.
Senior Tax Credits
Montgomery County runs two separate credits for older residents. If you are 65 or older and qualify for the state Homeowners’ Tax Credit, the county automatically adds a Senior Tax Credit equal to 50% of the combined state credit and county supplement. No separate application is needed, but you have to have applied for the Homeowners’ Tax Credit to trigger it.10Montgomery County, Maryland. Property Tax Credit and Exemption Information
A separate credit applies to longtime homeowners aged 65 and older who have lived in the same home for at least 40 consecutive years and whose dwelling is assessed at $700,000 or less. That one cuts county property taxes on the owner-occupied home by 20%.11Montgomery County, Maryland. Property Tax Credit for Elderly Individuals and for Military Retirees
Disabled Veteran Exemption
Veterans rated by the VA as 100% permanently and totally disabled from a service-connected cause may receive a full exemption from real property taxes on their dwelling and the surrounding yard.12Maryland Department of Veterans and Military Families. Tax Exemptions This is among the most valuable property tax benefits in Maryland. The application goes through SDAT.
When Payment Is Due
Property tax bills are due July 1 of the fiscal year, with payment accepted interest-free through September 30.13Maryland General Assembly. Maryland Code Tax-Property 10-102 – Property Tax Due Date Miss that date and the account is in arrears.
Bethesda owners can elect a semi-annual plan instead, splitting the bill into installments due September 30 and December 31.14Montgomery County, Maryland. Semi-Annual Tax Payment for Property Owners The county charges a service fee of up to 1.65% on the second installment to cover administration and lost interest.15Maryland Department of Assessments and Taxation. Question and Answers on Semiannual Property Tax Payment On a $6,000 bill, that adds roughly $50 to the second payment. Non-tax items on the same bill, such as front-foot assessments or trash fees, are due in full with the first installment regardless of plan.
Payment can be made through the Montgomery County online portal by electronic check or credit card, by mailed check to the Department of Finance, or in person at county payment centers. If your lender escrows your taxes, confirm with the servicer which schedule they are using.
What Happens If You Fall Behind
Delinquent property tax bills in Montgomery County accrue combined interest and penalty at 1⅔% per month, which works out to 20% annually (8% interest plus 12% penalty).16Montgomery County, Maryland. Delinquent Property Taxes On a $6,000 overdue bill, that is $100 added every month.
If the bill remains unpaid into the next year, the county sells the tax lien at a public auction held on the second Monday in June. Owners receive notice by mail in April, and a $60 advertising fee is added to the delinquent amount.17Montgomery County, Maryland. Tax Lien Sale Once the lien is sold, the purchaser can eventually foreclose if the owner does not redeem the property by paying the overdue taxes plus interest.
Appealing an Assessment
If the reassessment notice looks too high, you have 45 days from the date on the notice to file an appeal. Maryland uses a three-step process. The first step is an informal hearing at the supervisor’s level, where you meet with an assessor and present evidence. If that does not resolve things, you can appeal within 30 days to the Property Tax Assessment Appeal Board (PTAAB), an independent panel of local residents appointed by the Governor; there is no filing fee, and new evidence is allowed. The final administrative level is the Maryland Tax Court.
The strongest appeals rest on hard evidence: recent sale prices of comparable nearby homes, an independent appraisal, or documentation of structural problems. Given how much Bethesda’s housing stock varies block to block, comparable-sales data is usually where successful appeals are built. SDAT will provide the sales analysis for your area at no cost on request.18Maryland Department of Assessments and Taxation. Assessment Appeal Process
