Do I have to pay the pied-à-terre tax?

Only if both things are true: your NYC home is nobody’s primary residence, and its Department of Finance market value crosses the threshold for its class — $1 million for condos and co-ops, $5 million for 1–3 family homes.

The tax — officially the non-primary residence property surcharge — was enacted in the FY2027 New York State budget, passed May 27 and signed May 28, 2026, as new Article 30-C of the NY Tax Law (§§1350–1356). It applies in all five boroughs, from July 1, 2026 through a statutory sunset of June 30, 2031. In late July 2026 the city began notifying owners — roughly 17,000 letters — and published a supplemental market-value roll covering 959,710 residential properties that “may be subject” to it — phrasing that caused real confusion. Getting a notice does not mean you owe; it means DOF wants you to pay or prove an exemption.

Who’s in scope: owners of 1–3 family homes, condo unit owners, and co-op tenant-shareholders. The law also reaches property held through entities — a “covered owner” includes an individual holding a majority interest in the LLC, partnership, or corporation that owns the home, and the sole beneficiaries of a trust (Tax Law §1351). Two categories are excluded outright: property whose required certificate of occupancy hasn’t been issued, and new-development units still unsold under the sponsor’s offering plan.

How much is it?

The rates below apply to the property’s entire DOF “phase one market value” once it crosses the threshold — not just the slice above it, and not the price you paid.

This is the single most misunderstood part of the law, so let’s be precise. The statute’s base is “phase one market value” — the market value of the property as determined by the Department of Finance, i.e., the estimated market value printed on your annual Notice of Property Value. For condos and co-ops, state law forces DOF to value units as if they were rental buildings, so DOF’s number typically runs far below what a unit actually sells for — Hodgson Russ notes a unit worth $10 million on the open market might carry a phase-one value of only $500,000 to $1.5 million. That gap is why the condo/co-op rates look shockingly high: 4% of an artificially low value, not 4% of your purchase price. (Some law-firm alerts loosely call the base “assessed value” — the statute says market value as DOF determines it, a different and larger number than billable assessed value. Where summaries conflict, DOF controls.)

Phase 1 rates, per Tax Law §1353, for tax years July 1, 2026 – June 30, 2028:

And it is not marginal. As Rosenberg & Estis puts it, “Once the applicable threshold is met, the surcharge applies to the property’s entire Phase One market value — not merely the amount above the threshold.” A non-primary condo with a $1.2M DOF value owes 4% × $1.2M = $48,000 a year, on top of regular property tax.

Phase 2 — after June 30, 2028. The condo/co-op regime changes: DOF must compute a “phase two market value” using comparable sales of condo units, without the rental-valuation restriction — a number much closer to real sale prices. The threshold rises to $5 million for everything, and all classes pay the house-scale rates (0.8%/1.05%/1.3%). The exact methodology DOF will use hasn’t been published yet; that’s a genuine open question until DOF issues phase-2 guidance.

Revenue context: the city projects about $500 million a year; the NYC Comptroller’s office estimates $340–380 million after behavioral effects.

What counts as a primary residence — the exemptions

The property escapes the surcharge entirely if, as of the January 5 taxable status date, it’s the primary residence of the owner, an immediate family member, or a tenant under a genuine arm’s-length lease of at least one year.

The three exemption routes, from Tax Law §1352 and the definitions in §1351:

• The covered owner lives there. Primary residence is a facts-and-circumstances test — the statute looks at whether the home was occupied for a majority of days in the year, whether it’s the permanent address on your NY State income tax return, and whether you claim STAR (RPTL §425) or the NYC enhanced property-tax credit there.
• An immediate family member lives there. Defined in the statute as “a spouse, child, sibling, parent, grandparent, or grandchild” of the owner. A brownstone you own where your parent lives full-time is exempt.
• A real tenant lives there. A lessee (or lawful sub-lessee) who is a natural person, occupying under “a bona fide lease agreement negotiated in an arms-length transaction with a term of not less than one year,” using it as their primary residence. Investment condos with genuine year-lease tenants are out of scope.

DOF’s final rules (adopted July 14, 2026) add humane edges, per Rosenberg & Estis’s analysis: primary-residence status continues for one year after the resident’s death, and continuous hospitalization or a temporary nursing-facility stay doesn’t break it. There is no exception for intended future use — a unit you plan to move into doesn’t qualify. For entity ownership the rules are strict: majority owners can aggregate direct interests, but there’s no look-through for multi-tier structures, and a fractional-interest entity can’t confer covered-owner status. How DOF will treat every trust variation (contingent beneficiaries, split interests) is still being worked out case by case — DOF’s own commissioner has acknowledged “edge cases” in trust/LLC ownership and stale records.

What do I have to file, and when?

If DOF flags your property, you must submit an exemption application with proof of primary-residence status — the first-year deadline on DOF’s site is September 18, 2026. Do nothing and the determination becomes final and the surcharge goes on your bill.

The first-year sequence, from DOF’s guidance and its final rules:

• July 24–25, 2026 — DOF published an assessment-roll addendum listing properties that “may be subject” to the surcharge, with phase-one values.
• From July 23, 2026 — DOF mailed individualized notices (~17,000 letters); its rules require notice of primary-residence determinations by January 30 each year (August 30, 2026 for this first year), measured as of the January 5 taxable status date.
• September 18, 2026 — DOF’s posted deadline to submit an exemption application, via its online SmartFile forms (one for homes/condos, a separate one for co-op units), with an appeal window of 30 days from a determination notice.
• Appeals beyond DOF go to the NYC Tax Commission — you must pick a forum, not both — with judicial review after that.

Documentation runs through DOF’s portal: a tax return showing the address, driver’s license or voter registration, the unexpired lease plus a utility bill for tenant claims, birth/marriage certificates plus affidavits for family claims, operating agreements for entities. And the stakes are real: DOF can audit submissions for six years under its final rules (19 RCNY §62-04), and impose penalties of up to 50% of the surcharge for certifications that were materially inaccurate through negligence or bad faith (Sullivan & Cromwell).

Co-op owners, note: the surcharge for a flagged apartment is billed to the cooperative corporation’s property-tax account, and the co-op collects from the tenant-shareholder — an unresponsive shareholder’s surcharge becomes the building’s problem first. Boards should make sure flagged shareholders respond.

How to check a building’s DOF market value

Because the tax keys off DOF’s estimated market value — not sale price — the first practical question for any unit is simply: what does DOF say it’s worth?

That number is public record, on the property’s annual Notice of Property Value and in DOF’s assessment roll, keyed to the borough-block-lot (BBL).

Two honest caveats: DOF revises values annually, so the number can move before the next surcharge year; and for a co-op unit the phase-one value is an “imputed” per-unit slice of the building’s value — a building-level lookup shows the building, while DOF’s addendum lists the per-apartment figure.

What this means for buyers and investors

If you’re buying a $1M+ condo you won’t live in full-time, the pied-à-terre tax is now a five-figure annual carrying-cost line item — underwrite it before you bid.

Concretely, for due diligence:

• Non-primary buyers of $1M+ (DOF value) condos/co-ops: model 4–6.5% of DOF’s value annually through mid-2028, then re-model phase 2, where the threshold rises to $5M but the base jumps toward sale price. A unit that dodges phase 1 on a low DOF value may get caught in phase 2 — and nobody can model phase 2 precisely until DOF publishes its methodology, so treat projections past July 2028 as soft.
• Landlords: a genuine arm’s-length lease of 1+ year to a tenant who primarily lives there exempts the unit — the law deliberately spares rental inventory. Month-to-month and short-term arrangements don’t clearly qualify; paper your leases.
• Structure buyers: holding through a multi-tier LLC or a trust with multiple beneficiaries can cost you the exemption even when someone lives there, because no covered owner exists to claim it. Get structure advice before closing, not after the notice arrives.
• Co-op purchasers: ask the managing agent whether any units in the building carry unresolved surcharge flags — the building fronts the bill.

Whether the tax achieves its policy goals is debated — one economist told CNBC that similar taxes abroad “raise some revenues and lower vacancy, but they don’t lower rents or prices overall.” For a buyer the debate is irrelevant: it’s a real carrying cost from day one.

FAQ

Is the tax based on my sale price or the city’s value?

The city’s value. The statute applies the surcharge to “phase one market value,” which is the market value of the property as determined by the Department of Finance — the same estimated market value that appears on your annual Notice of Property Value. For condos and co-ops, DOF’s market value is usually far below what the unit would sell for, which is why the condo/co-op rates look so high.

Does the tax apply to the whole value or just the amount over the threshold?

The whole value. Once a property crosses its threshold, the applicable rate applies to the entire DOF phase-one market value, not merely the amount above the threshold. A non-primary condo with a $1.2 million DOF market value would owe 4% of the full $1.2 million — $48,000 — not 4% of the $200,000 excess.

My condo sold for $2 million — do I owe 4% of $2 million?

Not necessarily, on two counts. First, the tax only applies if nobody uses the unit as a primary residence — an owner, an immediate family member, or an arm’s-length tenant on a lease of at least one year each defuse it. Second, the base is DOF’s estimated market value, not your sale price, and for condos DOF’s value is typically a fraction of the sale price. Look up the DOF value for your unit before assuming anything.

What happens if I ignore the DOF notice?

The determination becomes final and the surcharge lands on your property-tax bill. DOF’s published deadline for exemption applications in the first year is September 18, 2026, and appeals run through the NYC Tax Commission. Missing the window generally forfeits the challenge for the year, and DOF can audit submissions for six years, with penalties of up to 50% of the surcharge for materially inaccurate certifications made negligently or in bad faith.

What if the apartment is owned by an LLC or a trust?

The law looks through simple structures but not complex ones. An individual holding a majority interest in the LLC, partnership, or corporation that owns the property can count as a “covered owner,” and so can the sole beneficiaries of a trust — so their primary-residence use can still exempt the property. But under DOF’s final rules there is no look-through for multi-tier entity structures, and an entity holding only a fractional interest can’t confer covered-owner status.

When does the pied-à-terre tax end?

The statute sunsets June 30, 2031, unless Albany extends it. Before then, the bigger date is June 30, 2028: after that, condos and co-ops move to a comparable-sales valuation with a $5 million threshold and the lower 0.8%–1.3% rates that houses use.
