Tax abatement

A tax abatement reduces the tax bill directly rather than the taxable value — the mechanism behind programs like the cooperative and condominium abatement and various improvement incentives. The exemption/abatement distinction is bookkeeping with consequences: they stack differently, phase differently, and appear in different fields of the tax records.

Like exemptions, abatements carry qualification conditions and clocks, and their expirations are scheduled cost changes. For unit owners, the co-op/condo abatement's requirements — primary-residence conditions among them — make its presence or absence on a unit's bill informative. For analysts, the benefit stack on any property is a documented, dated structure worth reading before projecting its taxes forward.
