New Hampshire has no statewide property tax cap and assesses property at full market value; Rockingham County revaluations occur every five years unless triggered earlier by sale, so your assessed value will reflect purchase price. New Hampshire offers no general homestead exemption, but the Elderly and Disabled Tax Exemption Program is available for qualifying seniors (65+) and disabled residents—contact the Rockingham County Assessor's office to determine income limits and required documentation. File your exemption application by April 15 of the assessment year and request the county's notice of assessed value to ensure accuracy.
