About All Island Tax Grievance

All Island Tax Grievance has helped thousands of homeowners lower their property taxes.

Founded by Cori Kaplan, a licensed attorney and real estate broker, All Island makes it easy for homeowners to deal with the often daunting world of “town hall.”  We research each case, file all necessary paperwork, and represent the final case in court if necessary.

All Island is a small business that provides personalized service, and our “win rate” is greater than 95%.  We offer a free, no-obligation initial evaluation — we’ll let you know upfront if you’re qualified to receive a tax reduction.  There is absolutely no fee or expense unless we successfully get you a tax reduction!
