Nobody plans to own a second home this way. A parent passes, the co-op they lived in for forty years comes to you, and somewhere between the estate paperwork and the family conversations, New York's new surcharge starts caring about a question no one has asked yet: who lives there now? The tax has no bereavement clause. From the day the apartment stops being anyone's primary residence, it is a non-primary residence — and if its DOF market value clears $1,000,000 (condo/co-op) or $5,000,000 (house), the meter is running while the family decides.
The four ways families hold an inherited apartment — and how each is taxed
1. A family member moves in (or stays)
The cleanest outcome. If an immediate family member of the owner — spouse, child, sibling, parent, grandparent, grandchild — occupies the apartment more than half the year as their primary residence, it's exempt. The surviving spouse staying put, the daughter who moves back in: both work, documented with the occupant's tax return, license, or voter card at the address. Note the relationship runs from the current owner(s): once the deed is in your name, your sibling qualifies; your late mother's cousin doesn't.
2. The estate holds it while probate runs
Probate does not pause the surcharge. An apartment sitting empty in the estate's name is a non-primary residence, and the statute's look-through rules reach through estates and trusts the same way they reach through LLCs — to the people. If administration will take a while and nobody's living there, the estate's fiduciary should treat the surcharge as a carrying cost in the accounting, and seriously consider a 12-month lease (below) rather than leaving value bleeding.
3. It goes into the family trust
Common, sensible for many estate reasons — and no shield here. Trusts are looked through, tiered structures are disregarded, and the analysis runs on the entire interest held. What matters is unchanged: does a qualifying person primarily live there? Trust questions have real edges (beneficiary occupancy, trustee powers over leasing) — this is exactly where the estate attorney earns their fee. What we can tell you precisely is the apartment's DOF value and exposure, so the attorney is deciding with real numbers.
4. Nobody can decide, so it sits
The expensive default. An empty inherited $2.2M-DOF-value condo owes $88,000 a year while the family circles. Listing it for sale doesn't stop the clock; neither does "we'll figure it out after the holidays." The two moves that stop it: a qualifying occupant, or a bona fide 12-month arm's-length lease — which converts the drain into income while everyone decides at leisure.
The co-op wrinkle heirs should know
Inherited co-ops carry a valuation surprise: DOF values co-op units by fractional share — your shares' slice of the whole building's value — not by what the apartment would fetch. In prewar buildings with big share allocations, longtime family apartments can test over the $1M line at numbers that shock heirs who remember what grandma paid. Before any family meeting, get the official figure: we pull it free, usually within the hour. Boards also gate estate transfers and leasing — factor board approval time into any lease plan.
This month's deadlines apply to estates too
DOF's notices don't distinguish grieving families from billionaires' pieds-à-terre. If a notice arrives addressed to the estate or the deceased, the same clocks run: 30 days to rebut with residency proof, exemption applications by September 18, 2026, notices all mailed by August 30. A notice sent to the empty apartment itself is the classic trap — make sure someone is checking that mailbox. Full response sequence: the notice playbook.
Questions owners ask
Does NYC's second home tax apply to inherited apartments?
Yes, if no qualifying person primarily lives there. An inherited condo or co-op that sits empty — in the estate, a trust, or the heirs' names — is a non-primary residence, and owes the surcharge once its DOF market value exceeds $1M (condo/co-op) or $5M (house). Probate does not pause it. Exemptions: an immediate family member of the current owner occupying it more than half the year, or a bona fide 12-month arm's-length lease.
Does a trust protect an inherited NYC apartment from the surcharge?
No. The statute looks through trusts, estates, LLCs and every tiered structure to the natural persons involved; what matters is qualifying occupancy, not the vehicle. Trust-specific edges (beneficiary occupancy, trustee leasing powers) belong with an estate attorney — armed with the apartment's actual DOF value.
Why is the DOF value of an inherited co-op so high?
DOF values co-op units by fractional share — the unit's shares as a slice of the building's total market value — not by likely sale price. Large prewar share allocations can push longtime family apartments over the $1M surcharge threshold at figures heirs don't expect. Check the official number rather than assuming.
