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.
What the mill rates are applied to
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)
- Mamaroneck school (2025–26): 12.451323 per $1,000 AV
- Scarsdale school (2025–26): 13.57657 per $1,000 AV
- County general + refuse (composite): 8.741627 per $1,000 AV
Estimates omit some special lines, and are pre-STAR: this roll carries no exemption codes, so a real bill is usually lower.
