The Department of Finance published a supplemental market value roll on July 24, 2026, related to the annual non-primary residence property surcharge. This roll includes, but is not limited to, all 1-, 2-, and 3-family homes and all co-op and condominium properties, as well as each individual co-op unit in a building in which at least one unit may be subject to the surcharge.
The vast majority of properties and units listed in the roll will NOT be subject to the surcharge. Only the roughly 17,000 property owners to whom DOF sent a letter are potentially subject to the surcharge. Property owners who received a letter that they may be subject to the surcharge should review DOF’s FAQ, and if needed, can submit a surcharge exemption application for residential homes and condos or co-ops.
