Who we work with, and how the work fits?

Updated 2026-07-28.

Most of this work arrives through someone who is already advising the owner. The property tax piece is the part we take.

An owner who opens the July 22 notice usually forwards it to somebody before doing anything else. That somebody is normally already in the file for other reasons, and now has a property tax deadline on their calendar that was not there in June. We work as the specialist under that relationship, not around it.

The desks we sit next to

  • Attorneys. Estate, trust, and real estate counsel who hold the operating agreement or the trust instrument, which is exactly the document the majority-interest and sole-beneficiary paths turn on.
  • Family offices. Often several units across several entities, where the answer differs unit by unit and the calendar has to be tracked centrally.
  • Accountants. The income tax return showing the address is the strongest single document DOF names, and the return preparer is the one who knows what it says.
  • Managing agents and co-op boards. On a cooperative the notice reaches the corporation, so the agent is holding paper that individual shareholders need. There is a board checklist for that half of the job.

What comes off your desk?

  • The qualification call: which of the five criteria the property can stand on, stated plainly, including when the answer is none of them.
  • Document collection and review, in the forms DOF actually accepts rather than the ones that feel persuasive.
  • The portal filing itself, with the notice's security code, before the extended September 18, 2026 deadline.
  • The calendar after it: 30 days from transmission to appeal an initial determination, and the March 2027 Tax Commission dates if value is the real dispute.
  • A record that can be handed to the next professional, or to DOF on audit, without reconstruction. The audit window runs six years.

Entities and trusts

This is where advisors are usually already involved, and where the paperwork is thickest. 8,900+ NYC condo units meet the value threshold and more than half are owned through LLCs, trusts, and other entities (MGNY analysis of FY2027 assessment rolls). Those units qualify only through people: one or more individuals who collectively hold a majority interest, an immediate family member of a majority holder, or the sole beneficiary of a trust.

The final rule tightened one edge and loosened another. Multi-tier entity structures cannot establish primary residence. Trusts got room: multiple individuals may collectively be sole current beneficiaries, and contingent or future interests do not automatically disqualify. Both readings live in the same file, which is why the organizational documents and the officer or trustee affidavit have to be read together rather than filed together.

To put a matter in front of us, call 212-343-1111 or send the owner to the free property review at pied-a-terre.mgnyconsulting.com. The services page has the rest of what this desk files, and the note on entity-owned units shows how one of these files reads in practice.
