| Appeal deadline | A formal appeal of real estate market value must be filed with the Board of Revision of Taxes (BRT) no later than the first Monday of October of the year preceding the tax year for which the revision is requested (prior-year basis). The deadline to file a 2027 tax-year market value appeal is October 5, 2026. Separately, an informal First Level Review (FLR) may be requested from the Office of Property Assessment after a property is reassessed, using the form mailed with the Notice of Proposed Valuation; an owner may pursue an FLR in addition to or instead of a BRT appeal, observing each deadline. |
