NYC's New Second-Home Tax: The Complete 2026 Pied-à-Terre Surcharge FAQ

If you own a New York City condo, co-op, or townhouse that isn't your primary residence, you may have recently received a letter from the NYC Department of Finance (DOF) about a new annual surcharge. The tax is real, it took effect on July 1, 2026, and for owners of qualifying properties it can run into the tens of thousands of dollars a year. This guide breaks down exactly what the Second-Home Annual Tax is, who it applies to, how much it costs, and — most importantly — the deadlines and documentation you need to secure an exemption if the property genuinely is someone's primary residence.

This is a fast-moving regulatory rollout, and DOF and the NYC Tax Commission continue to issue guidance as the first filing season plays out. For transaction-level tax questions, see my NYC mansion tax and transfer tax guide and full closing costs breakdown. For anything specific to your property, consult a qualified real estate attorney or tax advisor — this article is an informational overview, not legal or tax advice.

What Is the Second-Home Annual Tax?

Formally known as the non-primary residence surcharge, the Second-Home Annual Tax is a new statewide-authorized, city-administered levy on higher-value New York City residential properties that are not used as anyone's primary home. Unlike the mansion tax, which is a one-time charge paid at the moment of purchase, this is an ongoing annual surcharge that will appear on your property tax bill for as long as the property remains non-primary and the law stays in effect.

It applies to one-, two-, and three-family homes, condominium units, and cooperative apartments. Vacant land, unsold sponsor units still covered by an offering plan, bungalow colonies, and buildings without a certificate of occupancy fall outside the surcharge entirely, regardless of value.

Timeline: How Long Will the Tax Be in Effect?

• •Phase 1: July 1, 2026 through June 30, 2028
• •Phase 2: July 1, 2028 through June 30, 2031
• •The law sunsets after June 30, 2031 unless extended or replaced by future legislation
• •The first surcharge payment is due with the January 2027 property tax bill

How Much Is the NYC Second-Home Tax?

Rates and thresholds differ by property type and by phase. In Phase 1, condos and co-ops are valued using DOF's existing market-value methodology; in Phase 2, all covered property types move to a comparable-sales valuation approach, and the condo/co-op threshold rises to match one-, two-, and three-family homes.

One-, Two-, and Three-Family Homes (Phase 1 & Phase 2)

• •$5,000,000 – $14,999,999 in DOF market value: 0.80%
• •$15,000,000 – $24,999,999 in DOF market value: 1.05%
• •$25,000,000 and above: 1.30%
• •A two- or three-family home is fully exempt if at least one unit is a qualifying primary residence

Condominiums & Cooperatives — Phase 1 (2026-27 & 2027-28)

• •$1,000,000 – $2,999,999 in DOF market value: 4.00%
• •$3,000,000 – $4,999,999: 5.25%
• •$5,000,000 and above: 6.50%
• •The rate applies to the entire market value once a property crosses into that bracket, not just the amount above the threshold

Condominiums & Cooperatives — Phase 2 (starting 2028-29)

• •Threshold rises to $5,000,000, matching one-, two-, and three-family homes
• •$5,000,000 – $14,999,999: 0.80%
• •$15,000,000 – $24,999,999: 1.05%
• •$25,000,000 and above: 1.30%
• •Valuation shifts from DOF market value to a comparable-sales methodology, which has not yet been finalized

A Worked Example

Consider a condo with a current DOF market value of $1.3 million that recently sold for $8.4 million — a common gap between assessed and market value for NYC condos. In Phase 1, the surcharge is calculated on the DOF value: $1,300,000 × 4.00% = $52,000 per year. Once Phase 2 begins and the unit is valued using comparable sales, the same unit would owe $8,400,000 × 0.80% = $67,200 per year — illustrating why the shift to sales-based valuation in Phase 2 is expected to increase bills for many condo and co-op owners even though the rate itself is lower.

What Counts as a Primary Residence?

The surcharge does not apply if the property is the primary residence of any of the following:

• •The owner
• •An immediate family member of the owner — spouse, child, sibling, parent, grandparent, or grandchild
• •A tenant or subtenant under a genuine, arm's-length lease with a term of at least one year
• •One or more individuals who collectively hold a majority interest in the LLC, corporation, partnership, or trust that owns the property

Importantly, this is not a vacancy tax. A property used every weekend by its owner can still owe the surcharge if it isn't that owner's primary home, and a property that sits empty for stretches of the year can remain exempt if it's genuinely someone's primary residence — for instance, a family member's, or a tenant's under a qualifying lease. A person can also only claim one primary residence in New York City; owning multiple NYC properties doesn't create multiple exemptions unless each one independently qualifies through a family member or tenant.

Whether the property qualifies is determined as of a single "taxable status date" — January 5 of the year before the relevant tax year. Moving in, signing a qualifying lease, or restructuring ownership after that date generally won't change your liability until a future tax year, and the surcharge is not prorated for changes that happen mid-year.

Key Dates and Deadlines

• •January 5, 2026 — Taxable status date for the 2026-27 tax year
• •July 24, 2026 — DOF published its initial supplemental property list; check it directly rather than waiting for a letter
• •Late August 2026 — Outer deadline for DOF to mail initial determination notices for the first year
• •September 18, 2026 — Extended deadline to file a surcharge exemption application with DOF
• •January 2027 — First surcharge payment due, billed with the regular property tax bill
• •January 5, 2027 — Taxable status date for the 2027-28 tax year
• •March 1, 2027 — NYC Tax Commission filing deadline for condo and co-op owners
• •March 15, 2027 — NYC Tax Commission filing deadline for one-, two-, and three-family homeowners

Only roughly 17,000 property owners citywide received an initial letter, out of a much larger group of properties that appear on DOF's supplemental market value roll. Appearing on the roll does not mean you owe the surcharge — but if you did receive a letter and believe your property is exempt, missing the response deadline in that letter is the single biggest risk. Cooperative shareholders in particular should not assume a unit is exempt simply because it doesn't appear on the published list; DOF has said the published roll does not cover every qualifying co-op building.

How to Apply for a Primary Residence Exemption

If you received a DOF letter and the property is genuinely a primary residence, you'll need to submit a surcharge exemption application with supporting documentation before the deadline in your letter. The strongest single piece of evidence is your most recently filed state or federal income tax return showing the property as your permanent home address.

If a tax return isn't available or doesn't apply — for example, if a tenant or family member is the primary resident — DOF will generally accept two of the following: a driver's license or other DMV-issued ID showing the property address, a New York City voter identification card, or other documentation demonstrating occupancy during the twelve months before the taxable status date.

1. 1.Owner-occupied: submit your most recent tax return, or two qualifying identification documents.
2. 2.Tenant-occupied: submit the primary-residence documents above for the tenant, plus a copy of the current lease and one additional rental document (utility bill, proof of rent payment, or renter's insurance), or a Tenant/Subtenant Affidavit with two additional rental documents.
3. 3.Immediate family member: submit the family member's primary-residence documents plus proof of the relationship, such as a birth or marriage certificate, and DOF's Immediate Family Member Affidavit.
4. 4.Entity-owned property (LLC, corporation, trust, or partnership): submit the primary-residence documents for the majority owner, plus the entity's governing documents (operating agreement, articles of incorporation, or trust agreement) and a Majority Interest Affidavit.

What If You Disagree With the Valuation or Determination?

Owners have two distinct, and only partially overlapping, avenues for challenging a surcharge determination. A DOF appeal addresses only whether the property is a primary residence and generally must be filed within 30 days of the initial determination notice. A challenge filed with the NYC Tax Commission can address both the primary-residence determination and the property's market value, but comes with its own filing deadlines — March 1, 2027 for condos and co-ops, March 15, 2027 for one-, two-, and three-family homes.

Filing a Tax Commission challenge to the primary-residence determination generally closes off the DOF appeal path for that issue, though a separate market-value-only challenge remains available in every case. Because the rules and interplay between these two processes are technical — and because DOF has indicated that documentation submitted through this process isn't covered by standard tax-secrecy protections — owners weighing an appeal should consult a real estate tax attorney before choosing a path.

How Co-op Valuation and Collection Work

A cooperative unit doesn't have its own separately assessed value the way a condo or house does. In Phase 1, DOF imputes each unit's value by multiplying the co-op corporation's overall building value by that unit's proportionate share allocation. The co-op corporation itself is responsible for collecting the surcharge from the affected shareholder and forwarding the DOF notice to them promptly — and any resulting lien for nonpayment attaches at the corporation level, not just the individual shareholder's shares. Co-op boards should review their proprietary leases now to confirm they can pass the surcharge through to the specific shareholder whose unit triggered it.

How This Differs From the NYC Mansion Tax

It's easy to conflate the two, but they're structurally different taxes. The NYC mansion tax is a one-time buyer-paid tax assessed at closing, based on purchase price, and applies regardless of whether the buyer intends to live in the property. The Second-Home Annual Tax is an ongoing, annually recurring charge tied to DOF market value (or eventually comparable sales), and it applies only when the property is not a primary residence — a buyer who moves in full-time never owes it, no matter the purchase price. A single transaction can trigger the mansion tax at closing and, in later years, the second-home surcharge if the buyer's plans change and the unit becomes a pied-à-terre.

What This Means If You're Buying or Selling a Second Home in NYC

For buyers evaluating a condo or townhouse purchase above the relevant threshold, the surcharge should now be modeled as a recurring carrying cost alongside common charges, real estate taxes, and insurance — not treated as a one-time closing item. My buyer's guide to luxury NYC real estate walks through how to budget the full cost of ownership before you make an offer.

For sellers and owners of existing pied-à-terre properties, the surcharge changes the math on holding versus selling, particularly for condos and co-ops in the $1M–$5M DOF-value range where Phase 1 rates are steepest. If you're weighing whether to sell, convert the unit into a qualifying rental, or move a family member in to preserve primary-residence status, my seller's guide covers how carrying costs like this factor into pricing and net-proceeds strategy. A sale doesn't retroactively remove a surcharge already billed for the current tax year, since liability is fixed as of the January 5 taxable status date — so timing a sale around that date can matter.
