relative to limitations and qualifications for land placed in current use.

HB 1691 (New Hampshire) limits eligibility for property tax assessments based on current agricultural or conservation use. It restricts qualifying land to 40 acres per lot in semi-rural zones, 10 acres in developed zones with conservation land requirements, and prohibits clear-cutting or invasive species. Municipalities must cap current use approvals at 75% of rural zones and 5% of high-density zones, while requiring sustainable practices like invasive species management and limiting chemical use. Violations trigger retroactive tax payments using "best and highest use" rates from the last compliance date. This affects landowners currently enrolled in New Hampshire's current use tax program.
