Baltimore County property tax rate vs the rest of Maryland
Baltimore County has an effective property tax rate of 1.1% — its median real-estate tax bill ($3,645) as a share of its median home value ($330,000). That is above Maryland's 0.92% state average, and ranks the 4th highest of the 24 counties in Maryland.
Rates are set by local taxing bodies — the county, your city or town, and the school district — so two homes of the same value in different parts of Maryland can owe very different amounts. The calculator above starts from Baltimore County's 1.1% effective rate; adjust it to your exact municipality or add a homestead exemption for a closer estimate.

Divide by 12 for the monthly escrow amount your mortgage servicer collects — for example $321/month on a $350,000 home. These figures use the county effective rate; your local rate and any exemptions change the final bill.
How affordable is property tax in Baltimore County?
The typical Baltimore County homeowner pays about $3,645 in property tax against a median household income of $90,904 — roughly 4.0% of income a year.

How Baltimore County property tax is calculated
Baltimore County's assessor sets your home's assessed value, and local millage rates from the county, municipality and school district are applied to it; the 1.1% effective rate rolls all of that into one share of market value. To estimate your tax, multiply your home value by 1.1% (or your exact local rate), then subtract any homestead or senior exemption you qualify for. The calculator above does this and shows both the annual bill and the monthly escrow amount.
