What is the average property tax rate in Maryland?

Statewide, Maryland's effective property-tax rate is 0.975% — the state median real-estate taxes ($4,093) divided by the state median home value ($419,900), from the Census ACS 2020-2024 5-year estimates. The national figure is about 0.937%, which puts Maryland at #22 of 51 (1 = highest). Individual counties vary widely; the table above shows every one.

Which Maryland county has the highest property taxes?

By effective rate, Baltimore city is highest in Maryland at 1.461% (median bill $3,354), and Talbot County is lowest at 0.646% (median bill $2,647). Ranked by dollars paid rather than rate the order changes, because home values differ so much across the state — the table above shows both columns and sorts on either.

What property tax exemptions are available in Maryland?

The Homestead Property Tax Credit caps the annual increase in a home's TAXABLE assessment at 10% or less (every county/municipality must set a cap at or below that); a separate Homeowners' Property Tax Credit caps the tax bill as a share of gross income; a Renters' Tax Credit also exists. Eligibility and filing are handled by your county assessor, and the exemption you qualify for changes your bill far more than the county you are in — the rates above are county medians and do not account for any exemption.

How do I appeal a property tax assessment in Maryland?

Three appeal windows exist: within 45 days of a triennial reassessment notice; a petition for review by the first working day after January 1 in an off-cycle year; or within 60 days of a purchase between January 1 and June 30. Further appeal to the Property Tax Assessment Appeals Board is due within 30 days of the Supervisor's Level decision, then to Maryland Tax Court within 30 days of that. Missing the deadline usually means waiting a full year, so check the date on your own assessment notice rather than relying on a general figure.

How is property assessed in Maryland?

Unusually for a U.S. state, assessment is done by a STATE agency, not the county: the Department of Assessments and Taxation reassesses every property once every three years (one-third of the state each year). This is why an effective rate computed from market value — as every rate on this page is — will not match the millage rate printed on your bill: the two are applied to different bases.

Maryland property taxes by county

Statewide effective rate 0.975% · national rank #22 of 51 (1 = highest) · 24 county-equivalents · U.S. Census ACS 2020–2024 5-year

Across Maryland, the median owner-occupied home pays $4,093 a year in real-estate taxes on a median home value of $419,900 — an effective property-tax rate of 0.975%. That ranks Maryland #22 of 51 states and the District of Columbia (1 = highest). This page carries all 24 Maryland county-equivalents in the Census data — 24 with a published effective rate — sortable by rate, taxes paid, home value, income, or five-year change. 11 of them also carry a full detail card here — every median with its Census margin of error, both rankings, the six nearest counties, and the five-year change. It also sets out how property tax actually works in Maryland: how property is assessed, which exemptions exist and who qualifies, the deadline and body for an appeal, and the payment schedule and penalties — each hand-sourced from official Maryland sources. Figures are U.S. Census Bureau ACS 2020-2024 5-year estimates.

Statewide figures Maryland · ACS 2020–2024 5-year

Effective tax rate: 0.975%
Median real-estate taxes: $4,093 ± $21

How property tax varies across Maryland

Across Maryland's 24 county-equivalents with a published rate, the effective property-tax rate runs from 1.461% in Baltimore city down to 0.646% in Talbot County — a 2.3× spread inside a single state, which is why a statewide average tells a buyer very little.

The largest median real-estate tax bill in Maryland is $6,987 in Howard County, which ranks #2 of 24 by RATE — while the state's highest rate, 1.461%, is in Baltimore city, where the median bill is $3,354. Dollars and rate are different questions and rank counties differently.

Measured against the national median effective rate of 0.937%, 7 of Maryland's 24 ranked counties sit above it and 17 below. Maryland as a whole ranks #22 of 51 (1 = highest).

Median home value statewide is $419,900, but within Maryland it ranges from $640,300 in Montgomery County to $154,900 in Allegany County — the denominator of the effective rate, and the main reason two counties with similar bills can show very different rates.

Statewide, the median real-estate tax bill equals about 3.9% of median household income. That share is heaviest in Baltimore city (5.4%) and lightest in Somerset County (2.5%).

Comparing the non-overlapping Census periods 2015–2019 and 2020–2024, median real-estate taxes rose by a statistically significant amount in 22 of Maryland's 24 counties with a comparable trend, fell significantly in 0, and showed no statistically significant change in 2.

How property tax works in Maryland

Assessment, exemptions, appeals and payment are set by Maryland law and practice, so they apply to every county in the table above. Each fact is taken from an official government source and linked to it.

How property is assessed: Unusually for a U.S. state, assessment is done by a STATE agency, not the county: the Department of Assessments and Taxation reassesses every property once every three years (one-third of the state each year). source →
Exemptions & credits: The Homestead Property Tax Credit caps the annual increase in a home's TAXABLE assessment at 10% or less (every county/municipality must set a cap at or below that); a separate Homeowners' Property Tax Credit caps the tax bill as a share of gross income; a Renters' Tax Credit also exists. source →
Appealing an assessment: Three appeal windows exist: within 45 days of a triennial reassessment notice; a petition for review by the first working day after January 1 in an off-cycle year; or within 60 days of a purchase between January 1 and June 30. Further appeal to the Property Tax Assessment Appeals Board is due within 30 days of the Supervisor's Level decision, then to Maryland Tax Court within 30 days of that. source →

Official Maryland tax authority

Property tax in Maryland is assessed and collected locally. For an individual property's assessed value, exemptions, and bill, use the county assessor or appraisal district. For statewide rules and forms:

Frequently asked questions

What is the average property tax rate in Maryland?: Statewide, Maryland's effective property-tax rate is 0.975% — the state median real-estate taxes ($4,093) divided by the state median home value ($419,900), from the Census ACS 2020-2024 5-year estimates. The national figure is about 0.937%, which puts Maryland at #22 of 51 (1 = highest). Individual counties vary widely; the table above shows every one.
Which Maryland county has the highest property taxes?: By effective rate, Baltimore city is highest in Maryland at 1.461% (median bill $3,354), and Talbot County is lowest at 0.646% (median bill $2,647). Ranked by dollars paid rather than rate the order changes, because home values differ so much across the state — the table above shows both columns and sorts on either.
What property tax exemptions are available in Maryland?: The Homestead Property Tax Credit caps the annual increase in a home's TAXABLE assessment at 10% or less (every county/municipality must set a cap at or below that); a separate Homeowners' Property Tax Credit caps the tax bill as a share of gross income; a Renters' Tax Credit also exists. Eligibility and filing are handled by your county assessor, and the exemption you qualify for changes your bill far more than the county you are in — the rates above are county medians and do not account for any exemption.
How do I appeal a property tax assessment in Maryland?: Three appeal windows exist: within 45 days of a triennial reassessment notice; a petition for review by the first working day after January 1 in an off-cycle year; or within 60 days of a purchase between January 1 and June 30. Further appeal to the Property Tax Assessment Appeals Board is due within 30 days of the Supervisor's Level decision, then to Maryland Tax Court within 30 days of that. Missing the deadline usually means waiting a full year, so check the date on your own assessment notice rather than relying on a general figure.
How is property assessed in Maryland?: Unusually for a U.S. state, assessment is done by a STATE agency, not the county: the Department of Assessments and Taxation reassesses every property once every three years (one-third of the state each year). This is why an effective rate computed from market value — as every rate on this page is — will not match the millage rate printed on your bill: the two are applied to different bases.
