Tax Lot

A tax lot is a parcel identifier used for property tax administration and mapping; it is the unit typically used in tax maps and assessor records. In New York City processes, a zoning lot may or may not match a tax lot, and actions like tax-lot merges or splits may be required for mapping and administration purposes.

In practice

Operators often need both identifiers: tax-lot boundaries drive tax mapping and administrative filings, while zoning-lot boundaries drive entitlement/bulk computations.
