What this tool does
Baltimore City carries one of Maryland’s highest property tax burdens. This estimator applies the combined city-plus-state effective rate of about 1.55% to your home’s full assessed value, supports the Homestead assessment cap for owner-occupants, and lets you subtract a flat credit amount to estimate your annual bill.
How it works
Maryland assesses property at full market value, and Baltimore applies its rate directly:
taxable_value = homestead_capped_assessment (for primary residences)
gross_tax = taxable_value * 0.0155
net_tax = max(gross_tax - flat_credits, 0)
The Homestead Tax Credit limits how much your taxable assessment can grow year over year for an owner-occupied home, so a sharp reassessment does not immediately spike your bill. The estimator lets you enter a capped taxable assessment to reflect that protection, then subtracts any flat credits you qualify for.
Example and notes
On a home assessed at $250,000 with no extra credits: gross_tax = 250,000 * 0.0155 = $3,875/yr, or about $323/mo. If a $692 Homestead-related credit applies, the net drops to $3,183. The 1.55% figure blends Baltimore’s city rate (around $2.248 per $100 of value) with the state levy; special benefit districts can add small surcharges. Use this as a planning estimate and confirm the exact figure on your official Baltimore City tax bill.
