Overview
- City Hall announced the extension on Saturday and said it applies only to owners who received a Department of Finance notice saying they “may be subject to” the surcharge.
- The Department of Finance earlier published a supplemental market-value roll of more than 900,000 properties and then mailed preliminary letters to about 17,000 owners, triggering confusion and privacy complaints.
- Officials launched an online eligibility portal, expanded outreach and added staff to process exemption claims, but homeowners report technical glitches, heavy document requirements and some are hiring attorneys.
- The surcharge covers the 2026–27 and 2027–28 property-tax years and targets one- to three-family homes assessed over $5 million and condo/co-op units at lower thresholds, with the administration estimating roughly $500 million a year in revenue.
- Revenue and legal outcomes remain uncertain because exemptions, appeals, verification problems and possible market responses could change who pays and how much the tax ultimately raises.
