Baltimore Council Approves Property Tax Assessment Caps Starting July 2027
Baltimore homeowners will see new assessment caps applied to their annual bills beginning July 2027 under the reform approved by the City Council.
How we reported this
The Baltimore City Council passed the Property Tax Assessment Reform Act in June, which caps annual increases in assessed home values at 4 percent for owner-occupied properties. The measure applies to roughly 180,000 residential parcels inside city limits and takes effect with the next full reassessment cycle.
Why the Change Matters Now
City assessors completed a new round of property valuations in spring 2026 that reflected sharp rises in market prices since 2023. Without the cap, many owners would have faced double-digit jumps in taxable value. The reform follows similar steps already taken by the District of Columbia and by Montgomery County, Maryland, both of which set their own percentage limits on assessment growth.
Under the ordinance, a homeowner whose property assessment would otherwise rise from $250,000 to $310,000 will instead see the taxable value limited to $260,000. City budget documents project this adjustment will reduce total property tax collections by $12 million in fiscal year 2028, an amount offset by drawing from the city’s rainy-day fund.
Budget Details and Comparisons
Baltimore’s 4 percent cap sits between Philadelphia’s 3 percent limit and the 5 percent threshold used in parts of Prince George’s County. Local advocates note that the difference means a typical rowhouse owner in Baltimore could pay $180 less per year than a comparable owner in Philadelphia once both cities complete their 2027 assessments.
The legislation states that the cap applies only to primary residences and requires annual applications through the city’s finance department. Properties that change ownership reset to full market value. City officials project the first round of capped bills will reach residents by mail in December 2026.
Implementation begins with the distribution of revised assessment notices in October 2026. Residents who believe their capped value still exceeds market conditions may file an appeal by the standard January deadline. The finance department has added four temporary staff positions to handle the expected increase in filings.
