The building by the numbers

Every condo and co-op in New York is tested against the pied-à-terre surcharge on its DOF market value — the "Market Value" line on the Notice of Property Value (an income-derived Department of Finance figure), not the 45%-of-market assessed value on your regular tax bill. In The Residences at 400 Fifth Avenue, that test splits the building: 12% of units clear the $1,000,000 market-value threshold and owe a flat 4%–6.5% of their full market value for any year they are not someone's primary residence, while the rest owe nothing under Phase 1 (through June 30, 2028). Phase 2 re-tests everyone in 2028.

Owners in Midtown West: 12% of units here test over the $1M threshold, so the surcharge reaches a real share of this building. The exemptions are real, though: a unit occupied >half the year by you or an immediate family member, or leased arm's-length for 12+ months, owes nothing. The NYC pied-à-terre tax guide covers every rule; the free check below gives you your unit's exact numbers.

How much is the pied-à-terre tax at The Residences at 400 Fifth Avenue?
It is charged on a unit's full DOF market value, not the lower assessed value on your regular tax bill. A The Residences at 400 Fifth Avenue unit at the building's median DOF market value of $493,408 would owe about $0 per year in years it is not a primary residence, and the highest-valued unit here would owe up to $72,455 per year. DOF market values in the building run from $231,984 to $1,811,374 on the FY 2026–27 roll.
Which units at The Residences at 400 Fifth Avenue owe the pied-à-terre surcharge?
20 of 163 units (12%) are over the $1,000,000 DOF market-value threshold and owe the surcharge for any year they are not a primary residence; the rest owe nothing under Phase 1. The test is on DOF market value — the income-derived "Market Value" figure on the Notice of Property Value — not the lower assessed value. Whether a given unit actually owes in a given year also depends on use: the surcharge applies only when the unit is not someone's primary residence.
How can I avoid the pied-à-terre tax at The Residences at 400 Fifth Avenue?
A The Residences at 400 Fifth Avenue unit owes nothing in any of three cases: it is occupied more than half the year by you or an immediate family member as a primary residence; it is leased to a tenant on an arm's-length lease of 12 months or more; or it is sold.
