Maryland Property Tax Calculator 2026

The Maryland property tax calculator is a free, browser-based tool that estimates your annual property tax bill from your home's assessed value. It applies Maryland's roughly 1.05% effective statewide rate and returns an annual and monthly figure in seconds, with nothing sent to a server.

How Maryland Property Tax Works

Property tax in Maryland is an annual tax levied on real estate by local governments — primarily counties, municipalities, and school districts. The amount you owe is determined by your property's assessed value multiplied by the local mill rate. The statewide effective rate is approximately 1.05% of market value, placing Maryland 0.05% below the national average of 1.10%.

The effective rate combines all local levies: county tax, municipal tax, school district tax, and any special assessments. Because Maryland has multiple taxing jurisdictions, your actual rate depends heavily on where in the state your property is located. The 1.05% figure is a weighted average across all Maryland counties.

On the median Maryland home valued at $381,000, the typical annual property tax bill is about $4,001 — or roughly $333 per month when paid through a mortgage escrow account.

Who Collects Property Tax in Maryland — and How Rates Are Set

In Maryland, property taxes are assessed and collected at the county level. Each county has an assessor who determines property values and a treasurer (or equivalent office) who collects taxes. The state sets the framework and maximum rates; counties, municipalities, and school districts each add their own levies within those limits.

Mill rates (expressed as dollars of tax per $1,000 of assessed value) are set annually based on local budget needs. A mill rate of 10 equals a 1.0% effective rate. Most jurisdictions reassess properties every one to four years, though some reassess annually. If your home's market value rises faster than neighboring properties, your share of the tax burden can increase even if the mill rate stays the same.

To find your exact rate, contact your Maryland county assessor's office or check your county's official website. Your most recent property tax bill will also show the breakdown of all levies applied to your parcel.

Maryland Property Tax Exemptions and Relief Programs

Maryland offers homestead exemptions and may provide additional relief for seniors, veterans, and disabled residents. Contact your county assessor for details on available exemptions.

Veterans may qualify for a partial or full exemption depending on disability rating and service history. Agricultural land often receives a preferential assessment based on use-value rather than market value. If you believe your assessment is incorrect, you have the right to appeal — typically within 30 to 90 days of receiving your assessment notice.

To apply for any exemption, contact your county assessor. Most exemptions require an annual or one-time application and proof of eligibility (residency, age, disability documentation, etc.).

How to Appeal a Maryland Property Tax Assessment

If the number this calculator returns looks too high, the lever is the assessment, not the tax rate — rates are set by your county and the state, but the assessed value is appealable. Maryland's State Department of Assessments and Taxation (SDAT) reassesses every property on a three-year cycle, so roughly a third of the state is reassessed each year and you receive a Notice of Assessment. The deadline is short and easy to miss: an appeal must be filed within 45 days of the notice date, not 45 days from when you opened the envelope. Miss that window in a reassessment year and you can still file a petition for review by the first working day after January 1 for either of the two off-cycle years. The process runs in three escalating stages — a Supervisor's Level hearing first, then the Property Tax Assessment Appeals Board (which must be appealed within 30 days of the supervisor's final notice), and finally the Maryland Tax Court. Bring evidence, not opinion: recent sale prices of genuinely comparable nearby homes, photographs of condition problems, and any error in the recorded square footage, lot size, bedroom count or finished-basement status. A factual error on the property record card is the single most winnable argument, because it is objectively verifiable rather than a judgement call about value. Between cycles, assessments are only adjusted for a zoning change, a substantial change in use, extensive improvements, or a prior erroneous assessment. Updated 2026-08-03.

Tips to Manage Your Maryland Property Tax Bill

First, verify your assessment is accurate. Review your property record card at the county assessor's office and check for errors in square footage, bedroom/bathroom count, or lot size. Even small errors can inflate your assessed value and tax bill. If the assessment seems high, look up recent sale prices of comparable homes in your neighborhood and file an appeal if warranted.

Second, apply for every exemption you qualify for. Homestead, senior, veteran, and disability exemptions can reduce your taxable value by thousands of dollars. Third, if your mortgage servicer handles tax payments through escrow, review your escrow statement annually. Servicers sometimes over-estimate and hold excess funds — you may be entitled to a refund. Finally, Maryland property taxes are due July 1, with a 60-day grace period.

Is Appealing Your Maryland Property Tax Assessment Worth It?

At Maryland's 1.05% effective rate, a 10% assessment reduction on a $381,000 home saves about $400 a year, roughly $2,000 over five years — and Maryland reassesses each property on a three-year cycle, so a win holds for the rest of that cycle. The Tax After a Successful Appeal rows above run the numbers on your own home. Maryland gives three appeal levels: the Supervisor of Assessments, then the Property Tax Assessment Appeal Board, then the Maryland Tax Court, with 45 days to appeal after a notice of assessment. The three levels and the 45-day window are set by the Maryland Tax-Property Article § 14-502 and administered by the Maryland Department of Assessments and Taxation.
