How it works
Real property in Baltimore County is assessed by the State of Maryland at full market value on a triennial assessment cycle. Property tax is estimated by applying the Baltimore County real property tax rate and the Maryland state real property tax rate for non-utility property to the assessed value. For eligible owner-occupied properties, increases in taxable assessment may be phased in and limited under the Homestead Property Tax Credit program.
Examples
To estimate tax, the assessed value is divided by 100 and multiplied by the applicable county and state rates. The resulting amounts are combined to produce an estimated total property tax.
Limitations and important notes
