The forum election: DOF appeal or Tax Commission

There are two things an owner can be arguing about. Either DOF has the residency wrong, or DOF has the value wrong. They are different disputes with different forums, and the choice is not reversible on a whim.

The DOF path: residency

The response and any supporting documents go through the DOF portal. An appeal of an initial determination is made in writing through the same electronic portal, no later than 30 days after the date the notice of initial determination is transmitted, or if none is transmitted, 30 days after the surcharge appears on the assessment roll. No extension or hardship waiver exists, and what is left once that window closes is thin. One published summary says 90 days; the rule text says 30.

The Tax Commission path: value

A value challenge goes to the NYC Tax Commission on Form TC107. The deadlines are March 1, 2027 for Class 2 and March 15, 2027 for Class 1, or 30 days after DOF's final determination, whichever is later. What the form asks for, and what counts as the value being wrong, are worth settling before the form is started?

The consequence nobody reads twice

Asking the Tax Commission to review the exemption requires challenging the value as well, and choosing that route replaces the direct DOF exemption application. A Tax Commission determination controls and bars DOF reconsideration, which is the anti-forum-shopping provision the final rule added. So a file that only ever needed a corrected residency record can end up litigating a valuation it never disputed.

Choose the forum deliberately, in writing, with the reason recorded. If a property has both problems at once, that is a conversation worth having before either clock starts: 212-343-1111. How we run the file either way is on the services page?
