Mamaroneck property tax estimates
Dale Ledger estimates annual property tax for Town of Mamaroneck parcels using published mill rates applied to the town assessed value on the roll (SWIS 553289). This page explains what goes into that estimate and what it leaves out.
Low equalization, high-looking mills
The town roll is kept at 100% of full market value, so assessed value and market value are the same number and a mill rate here is directly comparable with any other town on the same basis.
Rates baked into Dale Ledger (2026)
- City rate (2026): 0.0 per $1,000 AV
- Mamaroneck UFSD (276 parcels are Scarsdale UFSD) (2025–26): 12.451323 per $1,000 AV
- County general + refuse (composite): 8.741627 per $1,000 AV
Estimates omit some special lines and only apply STAR when exemption codes appear on the parcel. Prior roll years are not fully ingested yet — year-over-year “Changes” filters stay hidden until they are.
