NYS Estate Tax Savings Opportunity [Private Client Services Alert]

February 12, 2014

Since the implementation in 2011 of federal legislation increasing the federal estate and gift tax exemption to $5,000,000, many New York residents have been making large lifetime gifts in order to substantially reduce their New York estate tax. Recently proposed legislation, if passed, will eliminate this tax reduction strategy by pulling back into the New York taxable estate at death lifetime gifts made by New York residents after March 30, 2014.
