The tax line on a Bethesda listing sheet looks like a fixed cost of the house, a number you can drop into a mortgage calculator next to principal, interest and insurance. It is closer to a record of the current owner's history. It shows how long they have held the property, whether their Homestead credit application is on file, and which year's bill the figure came from. In Montgomery County, very little of that history passes to the buyer at closing.
In levy year 2026, three separate mechanisms can each push a new owner's bill above the seller's. They stack. And because this fall's listings give buyers more homes to compare, the gap between the advertised tax and the real one belongs in the comparison.
The cap belongs to the owner, and it ends at the sale
Maryland, Montgomery County and the municipalities limit how fast an owner-occupant's taxable assessment can rise. The limit is 10% a year for a principal residence, or 5% in the Town of Kensington. It is called the Homestead Property Tax Credit. The Montgomery County Department of Finance states that this limit "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."
The county's Homestead credit explainer makes clear that the cap limits taxable assessment, not market value. That means a seller's capped taxable assessment can sit below the property's full assessment. A household that has owned through several rising reassessment cycles may be paying tax on a figure that has fallen well behind what the state says the home is worth. The buyer pays tax on the uncapped figure.
So two similar Bethesda houses listed with very different tax lines may cost about the same to own once they change hands. The lower number often just belongs to an owner who has been there longer.
Bethesda's reassessment is still working through the bills
That cap matters more this year because Bethesda was part of the most recent statewide revaluation. The Maryland Department of Assessments and Taxation reassessed Group 2 properties based on January 1, 2026 values and mailed notices on December 30, 2025, according to SDAT's release. Bethesda Magazine reported that the reassessment covered 94,059 taxable residential accounts in Montgomery County. It named Bethesda among the communities included, alongside Silver Spring, Potomac, Wheaton and Olney.
The size of the jump and the way it reaches tax bills are what matter for a buyer:
- The increase. Montgomery County residential values rose an average of 12.6% in this reassessment. Commercial values rose 11%.
- The phase-in. Increases are spread evenly across tax bills over three years. Decreases take full effect in the 2026 tax year.
- The illustration. Bethesda Magazine's example uses a hypothetical $1.03 rate, not a Bethesda-specific one. A home assessed at $400,000 in 2025 averages $450,400 in 2026, and the bill ends up $519 higher by the 2028 tax year.
For a buyer, the timing compounds. A seller's current bill reflects only the first step of the three-year phase-in, and it may also sit under the 10% cap. The buyer's bill steps up again in each of the next two years of the phase-in, starting from a base the cap no longer holds down. On Bethesda's larger assessments, each step is bigger in dollars than the magazine's $400,000 example.
A credit that appeared on last year's bill is $0 this year
The third change has nothing to do with assessments. For levy year 2025, Montgomery County homeowners with a Homestead application on file received a $692 Income Tax Offset Credit. It appeared on bills as "County Property Tax Credit." The County Council set it to $0 for levy year 2026. Bethesda Magazine's budget coverage reported that removing the credit freed funds for a progressive income-tax plan. It also meant some homeowners would see higher bills even though the FY27 property tax rate did not change.
The county's own FY27 letter puts both pressures side by side. With no rate change, the average county homeowner is still estimated to see a $23 monthly increase from rising assessments, on top of the credit going away.
So the year a tax figure comes from matters. A levy year 2025 bill had the $692 credit subtracted. The current levy year's bill, covering July 1, 2026 through June 30, 2027, does not. The county also notes that a Homestead application must be on file with SDAT by May 1, 2027 for the credit to appear on bills starting July 1, 2027, if the Council sets it above $0 in a future year.
Where in Bethesda the house sits changes the rate itself
Assessment is only half the calculation. The rate it is multiplied by changes across short distances in and around Bethesda, because several incorporated towns and villages add their own municipal tax. The county's 2026 levy year rate schedule lists these total real property rates per $100 of assessed value:
| Jurisdiction | Municipal rate | Total rate per $100 |
|---|---|---|
| Chevy Chase Village | $0.2920 | $1.3250 |
| Village of Martin's Additions | $0.2620 | $1.2950 |
| Section 3, Village of Chevy Chase | $0.1000 | $1.2521 |
| Town of Chevy Chase | $0.0400 | $1.1921 |
| Somerset | $0.0200 | $1.1721 |
| Section 5, Village of Chevy Chase | $0.0050 | $1.1571 |
| Standard class | none | $1.1521 |
Parcels inside the Bethesda Urban District carry one more special-area component, listed at $0.0120 per $100 in the county's FY27 budget schedule. The county says which special-area taxes apply "depends on where the property is located." Municipal taxes pay for services such as street and sidewalk upkeep, trash removal and tree care, and those services differ by municipality.
For a simple illustration, apply the table to a $1,000,000 assessment. The highest rate listed comes to about $1,729 a year more than the standard class. That difference sits on top of everything the cap reset and the credit change already added. Two listings with the same Bethesda mailing address and the same price can carry noticeably different costs before either is reassessed again.
The disclosure exists for this reason, and it has limits
Montgomery County requires sellers of residential property to estimate and disclose the next levy year's property tax to a prospective buyer. The county's stated reason is that the buyer won't get the Homestead credit in the first year, so "the difference between the current year's and next year's tax can be significant."
The Office of Consumer Protection's estimator takes an address or account number. It estimates the taxes and non-tax charges a new owner would pay in the first full fiscal year. Its method page explains how it gets there:
- It uses next fiscal year's phase-in value if known, otherwise the current year's.
- It applies current-year State, County and municipal rates.
- It applies no tax credits.
- It holds next year's non-tax charges at current-year levels.
- It must be updated each July 1, because future rates are not yet set.
Because it applies no credits, the estimate is a closer guide to a buyer's first year than the seller's own bill, which may reflect the cap. It is still an estimate. Rates for the following year haven't been set, and the second and third steps of the 2026 phase-in will keep raising the assessment after that.
Why this belongs in the comparison right now
Buyers have more homes to weigh against each other this fall. The Greater Capital Area Association of REALTORS' September 2026 Montgomery County report recorded a $610,000 median sale price for September, up 1.8% year over year. New pending sales fell 17.7% and new listings rose 2.8%. Bright MLS's September 2026 data showed county active listings up 27.2% from a year earlier, with 3.00 months of supply and 34 average days on market. These are countywide figures, not Bethesda-only figures.
When supply grows and pending sales slow, buyers are more often choosing among several homes at once. Choosing well depends on comparing what each one costs to own, and the list price shows only part of that. A $15,000 price difference can be smaller than the combined effect of a reset cap, a missing credit and a municipal rate over the years you plan to stay.
A few direct questions
Will my first bill definitely be higher than the seller's? Not always. The cap reset only matters when the seller's capped taxable assessment sits below the full phased-in value. A recent purchase or a flat assessment history narrows the gap. The disclosure and the OCP estimate exist so a buyer can see the likely figure before committing.
When are Montgomery County taxes due? According to the county Department of Finance, principal residences are billed semi-annually unless the owner pays in full by September 30. The first installment must be received by September 30 and the second by December 31. Payments that arrive late are charged interest and penalty.
Does the Homestead credit ever apply to a buyer? The county says the cap does not apply in the first year after purchase, and that a one-time Homestead application with SDAT is required. Details are on SDAT's Homestead page.
