The one thing to understand first
The surcharge is computed on your unit's DOF market value — the Department of Finance's income-derived figure on the assessment roll — never on what you paid. For condos and co-ops that figure typically runs around 25–40% of open-market price: the TriBeCa condo at 56 Leonard that trades around $4.5M carries a DOF market value of $1,390,768. For 1–3 family houses the opposite holds — DOF values them near true market, so price is a fair proxy. Every estimate below flows from that split, and every bracket is a flat rate on the full value, not a marginal rate on the excess.
The actual 2026–2028 schedules
| Property | DOF market value | Rate (flat, on full value) |
|---|---|---|
| Condos & co-ops | $1M – $3M | 4% |
| $3M – $5M | 5.25% | |
| Over $5M | 6.5% | |
| 1–3 family houses | $5M – $15M | 0.8% |
| $15M – $25M | 1.05% | |
| Over $25M | 1.3% |
Condos & co-ops, price point by price point
Ranges reflect where DOF values typically land across the 630 buildings in our database; individual buildings vary widely, which is exactly why the roll number decides.
| Purchase price | Typical DOF value | Likely annual surcharge (non-primary) |
|---|---|---|
| $1.5M | ~$400K – $600K | $0 — under the $1M threshold |
| $2M | ~$550K – $800K | Usually $0; high-income buildings can clear $1M → ~$40K+ |
| $3M | ~$850K – $1.3M | Straddles the line: $0 or ~$40K–$52K (4%) |
| $5M | ~$1.4M – $2M | ~$56K – $80K (4%) |
| $8M | ~$2.2M – $3.2M | ~$90K – $170K (4% or 5.25%) |
| $15M | ~$4M – $6M | ~$210K – $390K (5.25% or 6.5%) |
| $25M+ | often $7M+ | $455K+ (6.5%) — the verified extreme: a 220 CPS unit at $15.55M DOF owes $1,011,001 |
Two honest caveats. First, the $2M–$3M band is where guessing hurts most: the difference between a $980K and a $1.05M roll value is the difference between $0 and $42,000 a year, forever. Second, these are Phase 1 numbers — from July 2028, Phase 2 re-tests everything at a single $5M threshold on comparable sales, which will pull many high-priced condos out and some back in.
Townhouses & 1–3 family houses
| Market value ≈ price | Annual surcharge (non-primary) |
|---|---|
| Under $5M | $0 |
| $6M | 0.8% → $48,000 |
| $10M | 0.8% → $80,000 |
| $20M | 1.05% → $210,000 |
| $30M | 1.3% → $390,000 |
What the annual number really buys you: a decision
Unlike the one-time mansion tax you paid at closing, this charge is a live yearly choice: pay it, lease your way out with a 12-month arm's-length tenant, move immediate family in as their primary home, or sell and redeploy — though before selling to escape the tax, read Sell or Bridge to 2028?: for sub-$5M homes the exit usually costs more than the two-year bridge. Owners abroad have their own playbook — see the foreign owners guide. And if DOF's value itself looks wrong, it can be challenged.

"THE DEADLINE FOR SUBMITTING AN EXEMPTION APPLICATION IS EXTENDED TO OCTOBER 6, 2026"
"For property tax years 2026-27 and 2027-28, the surcharge may apply to: One-, two-, and three-family homes valued by DOF at more than $5 million; Condominium and cooperative units valued by DOF at $1 million or more."
"Your property will not be subject to the surcharge if it is the primary residence of any of the following: The owner of the property. A tenant or subtenant. One or more individuals who collectively hold a majority interest in the LLC, corporation, or partnership that owns the property. An immediate family member of the owner or majority interest holder. The sole beneficiary or beneficiaries of a trust."
| Property type | DOF market value | Surcharge rate (% of market value) |
|---|---|---|
| One-, two-, and three-family homes | $5,000,000 or greater, but less than $15,000,000 | 0.8% |
| $15,000,000 or greater, but less than $25,000,000 | 1.05% | |
| $25,000,000 or greater | 1.3% | |
| Condominium and cooperative units | $1,000,000 or greater, but less than $3,000,000 | 4.0% |
| $3,000,000 or greater, but less than $5,000,000 | 5.25% | |
| $5,000,000 or greater | 6.50% |
Documents DOF lists for an exemption: for each occupant claimed, the most recently filed federal or state tax return, or a driver's license or other DMV-issued identification (or, failing both, a voter identification card plus other proof of primary residence); for a tenant or subtenant, additionally a copy of the current lease and one more rental document, or a Tenant or Subtenant Affidavit and two rental documents. DOF also states it "published a supplemental market value roll on July 24, 2026" that "includes, but is not limited to, those properties that may be subject to the surcharge."

NYC Department of Finance — Notice of Adoption of Final Rules (adopted July 14, 2026)
"This surcharge, colloquially known as the pied-à-terre tax, imposes an additional tax that is calculated as the product of a surcharge rate established by statute and the market value of the applicable property, or with respect to a residential cooperative property, a residential cooperative dwelling unit."
"Because the surcharge is based on market value, not assessed value, DOF notes that these rolls are required to include the applicable market values of properties, not assessed values."
"An individual cannot have multiple primary residences."
The rules cite Administrative Code § 11-3201 (defining "primary residence") and §§ 11-3202 to 11-3204 (the surcharge computation) and were adopted under part HH of chapter 59 of the Laws of 2026, adopted into law May 28, 2026. Full rule text and our method notes: Methodology.
Statute and fiscal estimate
New York Tax Law Article 30-C (§ 1351 definitions, including § 1351(k), which defines the base as the market value determined by the Department of Finance; § 1353 thresholds and rates), enacted as part HH of chapter 59 of the Laws of 2026. The NYC Comptroller's Fiscal Note 2-2026 projected the surcharge would reach about 11,200 of the highest-value non-primary properties for roughly $340–500 million a year.
