A property tax rate below county and state medians

Severn's median effective property tax rate ran 1.07% this pass (Ownwell), below both Anne Arundel County's 1.09% median and Maryland's 1.21% statewide median.

A genuinely complex, graduated local income tax

Anne Arundel County uses a real, graduated, income-tiered local piggyback tax rather than a flat rate -- one of only two Maryland counties (with Frederick) to do so. This project's own prior Anne Arundel County research carried a real, disclosed cross-source spread on the exact bracket figures; confirm current, specific thresholds directly with the county Comptroller's office.

Rising Anne Arundel County flood-insurance considerations

Anne Arundel County participates in the NFIP and requires flood insurance for federally-mortgaged properties in FEMA Special Flood Hazard Areas, given the county's real, disclosed 266 flood-related events recorded since 1996.
