The value of your Westchester County home is the primary factor used to determine your annual property tax bill. You have the right to object to the assessor’s value, but you must do so within the time set by your town or municipality. The third Tuesday in June (June 17, 2025) is the closing date for filing grievances.
O’Connor is passionate on your behalf, pursuing every applicable appeal, including the Small Claims Assessment Review (SCAR), to obtain the best tax decrease. Annual property tax appeals consistently produced the best results, according to our 50 years of real estate experience. We can create arguments for your decrease based on both unequal evaluation and market value gaps thanks to our strong evidence and vast proprietary data.
