Which NYC property tax lookup shows what I actually owe?
Your Property Tax Bill screen shows the current amount due, including tax, exemptions, abatements, credits, and—if applicable—the pied-à-terre surcharge. This is the only DOF lookup that tells you what must be paid and when.
The other two screens serve different purposes. The Property Assessments lookup shows assessed value and market value for valuation review. The Annual Notice of Property Value explains DOF's current valuation determination but doesn't calculate your bill.
Where do I find my property's market value for the pied-à-terre tax?
The market value appears on both the Property Assessments screen and your Annual Notice of Property Value, mailed each January. For the pied-à-terre surcharge, DOF uses this market value figure—not the assessed value.
Conquest's analysis of DOF's July 2026 Supplemental Market Value Roll shows roughly 24,000 units citywide would owe the surcharge if they are non-primary residences. In Manhattan, 16,709 condos and co-ops fall above the $1 million threshold, with an average surcharge of $68,559.
The surcharge applies flat rates to the full market value once you cross the threshold: 4% for condos and co-ops valued $1 million to $3 million, 5.25% from $3 million to $5 million, and 6.5% above $5 million.
Why is my assessed value different from my market value?
DOF applies assessment percentages to convert market value into assessed value for regular property tax calculations. Tax Class 1 properties use 6% of market value. Tax Classes 2 and 4 use 45%.
A $2 million condo's assessed value would be $900,000 (45% of $2 million) for regular tax purposes. But the pied-à-terre surcharge uses the full $2 million market value, creating a $80,000 annual surcharge at the 4% rate.
This distinction matters because many professional summaries incorrectly state the surcharge applies to assessed value. DOF's adopted rules specify the surcharge 'is based on market value, not assessed value.'
What's the difference between being on the supplemental roll and owing the tax?
DOF published its supplemental market value roll on July 24, 2026, listing properties that may be subject to the surcharge. Appearing on this roll doesn't establish liability.
Properties DOF believes are subject to the surcharge receive direct notice and an opportunity to respond. The exemption application deadline is October 13, 2026, for both residential homes and cooperative units.
Primary residences are exempt, along with properties occupied by immediate family members or 12-month arm's-length tenants. Most properties above the threshold are primary residences and owe nothing.
When will the surcharge appear on my tax bill?
If imposed, the surcharge appears on the NYC property tax bill due January 1, 2027. DOF was required to mail surcharge notices by August 30, 2026, for the fiscal year beginning July 1, 2026.
The surcharge runs through June 30, 2031, when the law sunsets. Starting July 1, 2028, condo and co-op rates will shift toward the lower house schedule based on comparable sales, though specific figures aren't yet determined.
How do I appeal the market value or primary residence determination?
For 2026-27 and 2027-28 tax years, Tax Commission appeals are due March 1, 2027, for Tax Class 2 properties and March 15, 2027, for Tax Class 1 properties when appealing both the primary-residence determination and market value.
Market value appeals alone follow the same March deadlines. Owners get 30 days from a notice's transmission date to appeal the primary residence determination to DOF directly.
Which neighborhoods face the highest exposure?
Manhattan's 10019 zip code leads with 975 condo and co-op units above the threshold, averaging $86,862 in potential surcharge. SoHo's 10012 follows with 932 units averaging $86,469.
Brooklyn shows 3,311 houses above the $5 million threshold, with an average surcharge of $52,630. The borough's 649 condos and co-ops above $1 million average $57,678 in potential liability.
Roughly 4,400 condo and co-op units sit within $100,000 of the $1 million threshold, meaning small valuation changes could push them into surcharge territory.
Frequently asked questions
Is my apartment subject to the pied-à-terre tax if it's on the supplemental roll?
Appearing on DOF's supplemental market value roll doesn't establish liability for the pied-à-terre surcharge. Properties DOF believes are subject to the surcharge receive direct notice and an opportunity to respond, with primary residences being exempt along with properties occupied by immediate family members or 12-month arm's-length tenants.
How much is the pied-à-terre tax on a $2 million condo?
A $2 million condo would face an $80,000 annual surcharge at the 4% rate. The surcharge applies flat rates to the full market value: 4% for condos and co-ops valued $1 million to $3 million, 5.25% from $3 million to $5 million, and 6.5% above $5 million.
Does the pied-à-terre tax use assessed value or market value?
The pied-à-terre surcharge uses the full market value, not the assessed value. DOF's adopted rules specify the surcharge 'is based on market value, not assessed value,' which appears on both the Property Assessments screen and your Annual Notice of Property Value mailed each January.
