In order to have your property classified as Homestead, you must file the HS 122 form. This is statutorily mandated reporting for anyone who owns property in Vermont. There is no extension for this process and there may be penalties imposed during the property tax billing cycle.
The final deadline for filing your HS122 return and receiving the homestead classification is October 15. If you anticipate filing for an Income Sensitivity Adjustment (state tax credit aka state payment), it is important that you file the homestead each year. Further specific information regarding Homestead filing can be found at the Tax Department or by calling 866-828-2865 (toll-free in Vermont) or 802-828-2865 (local and out-of-state).
