Maryland Property Tax Calculator - MD Property Tax Estimate

The Maryland property tax calculator estimates the annual and monthly real property tax you owe on a Maryland home from its market value, your local county or Baltimore City rate, the statewide rate, and any credit you claim. Maryland builds the bill from the assessed value multiplied by a tax rate stated as dollars per $100 of assessed value, so this tool follows the same rate-per-$100 method the state uses.

• • Compare counties before buying: Compare the property tax cost of homes in different Maryland counties before making an offer.
• • Model a reassessment: Model the bill after a triennial reassessment raises the assessed value.
• • Estimate escrow: Estimate the monthly escrow amount a lender will require.
• • Check credits: Check whether the Homestead or Homeowners' credit lowers your net bill.

Use the tool before you buy a home to compare the carrying cost across counties, when you receive a reassessment notice to check the new bill, or each spring to model how the homestead and homeowners credits change what you pay. Pair the result with the Maryland paycheck calculator if you also want to see the income side of your household tax picture.

The estimate is informational only. Your official bill comes from your local assessor and the Maryland Department of Assessments and Taxation (SDAT), which may apply district levies or credits this calculator does not model.

Maryland generally issues property tax bills twice a year, in July and December, so the annual figure here splits into two payments rather than one. When a mortgage servicer escrows for taxes, it collects one-twelfth of the annual amount every month and pays the county on your behalf, which is why the monthly number is as useful as the annual one when you compare a home's total carrying cost.

Pair the property tax result with the Maryland paycheck calculator to see the income side of your household tax picture.

The calculator converts the rate-per-$100 convention into a single decimal, applies it to the assessed value, and then subtracts any credit you enter. The same method appears on every Maryland tax bill.

• marketValue: Full market value of the home before the assessment ratio is applied.
• assessmentRatio: Percent of market value used as the assessed value; Maryland law sets this at 100%.
• localRatePer100: Your county or Baltimore City rate in dollars per $100 of assessed value.
• stateRatePer100: The statewide rate, currently $0.112 per $100 of assessed value, set each year by the state.
• homesteadCredit: Annual credit from the Homestead Tax Credit or the income-based Homeowners' credit, if known.

Maryland assesses at 100% of market value, so the assessed value normally equals what the home would sell for. The state rate and your local rate are each quoted in dollars per $100, so a $1.10 rate means $1.10 of tax for every $100, or 1.10%. Dividing by 100 turns that into the decimal used in the multiplication.

According to Maryland Department of Assessments and Taxation, SDAT publishes the annual state property tax rate and each county and Baltimore City's local rate expressed as dollars per $100 of assessed value.

According to Maryland Tax-Property § 9-105, The Homestead Tax Credit caps the annual increase in the taxable assessment of an owner-occupied principal residence, currently at 10%.

Four ideas explain most of the variation in Maryland property tax bills. The Maryland property tax calculator follows the same rate-per-$100 structure that SDAT uses on every bill, so understanding these ideas lets you read your own notice with confidence.

The interaction of these ideas matters: the local rate sets the level, the assessment ratio sets the base, and the credits set how much of that is finally collected from you.

Because the local rate and the assessment ratio move independently, two neighbors with identical homes can owe different amounts if one sits in a higher-rated district or has not yet been reassessed to full value. Reading the rate-per-$100 figure from your own notice, rather than a statewide average, is the surest way to estimate what you actually pay.

Follow these steps to produce a realistic estimate of your Maryland property tax.

1. 1 Enter market value: Enter the market value of the home, or the price you expect to pay.
2. 2 Set the assessment ratio: Keep the assessment ratio at 100% unless your locality is known to assess below full value.
3. 3 Enter the local rate: Enter your county or Baltimore City rate per $100; look it up on the SDAT rate table if you are unsure.
4. 4 Confirm the state rate: Leave the state rate at the default $0.112 per $100 unless the state has changed it for the year.
5. 5 Add credits: Add any homestead or homeowners credit you have been approved for.
6. 6 Read the results: Read the annual and monthly tax and the effective rate, then compare them across counties.

A buyer weighing a $350,000 home in a county rated at $1.10 per $100 versus Baltimore City at $2.268 per $100 can see the annual bill swing from about $4,242 to $8,330 before factoring any credit.

Add the monthly property tax from this tool into the mortgage calculator to estimate the full payment.

Using the calculator gives you concrete numbers for decisions you would otherwise guess at.

• • Compare counties: Compare the true carrying cost of homes across Maryland counties before you commit to a purchase.
• • Catch reassessment errors: Catch reassessment errors early by modeling the new assessed value against your expected bill.
• • Plan escrow: Plan your monthly escrow and cash flow instead of being surprised by the semiannual bill.
• • See credit impact: See the dollar effect of the Homestead and Homeowners' credits so you know whether to apply.
• • Fuller tax view: Combine the property tax figure with your income tax planning for a fuller household tax view.

None of this replaces the official bill, but it helps you ask the right questions when the assessor's notice arrives.

Four inputs drive almost all of the difference between estimates.

• • The estimate models the county, Baltimore City, and state rates only; it does not include fire, sewer, or special taxing-district levies some localities add.
• • The Homestead credit is modeled as an approximate annual amount; the exact credit depends on your reassessment history and is confirmed by your local assessor.

Treat the output as a planning figure. The SDAT rate table and your local jurisdiction set the final numbers.

A Maryland property tax calculator is only as accurate as the local rate you enter, so pull the current dollars-per-$100 figure from your county's published table before you rely on the amount for a purchase or refinance decision.

According to Maryland Homeowners' Property Tax Credit Program, The Homeowners' Property Tax Credit is an income-based credit that lowers the net property tax for eligible owner-occupants.
