The New York State Department of Tax and Finance has published a form for distribution to new homeowners providing guidance on the new STAR tax credit program. Homeowners who purchased their current home prior to May 1, 2014 and already receive the STAR exemption under the current program do not have to do anything. There are no changes for them and they will continue to receive their STAR exemption. If a homeowner purchased a home between May 1, 2014 and Aug. 1, 2015, they may fall under the new STAR credit program and may have to apply. More information can be found here. Homeowners who purchased after Aug. 1, 2015 will fall under the new STAR credit program and will have to register here.
