Your home can be completely exempt from Virginia real property tax if the VA rates you 100 percent service-connected total and permanently disabled, or rates you individually unemployable. The exemption covers the home that is your principal residence and up to one acre of the land it sits on.
Apply through the commissioner of the revenue or the assessor for the county, city or town where the home is, not through the state. Ask them what proof they want and when they need it, because filing practice varies between localities.
