Tax Commission

The Tax Commission is New York City's independent administrative body for assessment review: property owners apply during the annual window for correction of tentative assessments, the Commission reviews and can order reductions, and its process is the required predicate for continuing into court through certiorari proceedings. It is institutionally separate from the Department of Finance, whose valuations it reviews.

For income-producing properties, applications typically ride on the owner's filed income and expense data, making the process a structured annual negotiation between claimed and assessed value. Application and outcome records add a layer to a building's financial paper trail — including, occasionally, the silence of an owner who never contests anything.
