Should local governments impose land-use taxes on property converted for solar energy arrays?

The New Hampshire Board of Tax and Land Appeals reduced a Land Use Change Tax assessment on a 70-acre property from $8,000 to $6,060. The ruling determined that only 0.48 acres containing a solar array were subject to taxation.

Why it matters

This decision limits the scope of Land Use Change Tax applications for properties enrolled in the Current Use program by requiring clear evidence of a land use change. It specifically clarifies that only the land occupied by infrastructure and its curtilage is eligible for assessment.

The Board calculated the tax based on 58 percent of the buildable lot value for the 0.48-acre section containing 72 solar panels. Assessments on the remaining portion of the 70-acre property were rejected due to insufficient evidence of land use changes.

New Hampshire Board of Tax and Land Appeals

This administrative body oversees tax appeals and land use disputes within the state of New Hampshire.

The details

The Board ruled that the town failed to establish the precise timing for changes in use across the property, leading to the rejection of additional tax claims. Consequently, the tax liability was restricted solely to the footprint of the solar installation and its curtilage.

Market Dynamics

This ruling clarifies the application of the New Hampshire Current Use program by narrowing the definition of land subject to tax when solar arrays are installed. It signals a shift in how administrative boards interpret land tax liabilities for renewable energy infrastructure.

Property owners enrolled in land conservation programs should note that only the specific portion of land converted for infrastructure is typically subject to reassessment. This outcome provides a precedent for challenging tax bills that exceed the actual area of land use change.

The takeaway

Taxpayers should ensure that municipalities provide specific evidence of land use change for the entirety of a property before accepting a tax assessment. Documenting the precise footprint of any installed infrastructure can be essential when contesting land tax liabilities.
