TAXATION – Amends existing law to revise a provision regarding the assessment of certain property.

This Idaho bill (H 551) revises how counties assess property taxes for new construction. It requires counties to include only 90% of the taxable market value increase from new buildings, additions, or manufactured housing in property tax rolls - down from 100% under prior law. Exceptions apply to certain urban renewal areas (80% valuation) and specific cases like electricity generation improvements or previously exempt state university facilities. The change directly affects property owners who build new structures or make significant additions, as it reduces the tax burden on new construction value. The bill also clarifies reporting deadlines for county assessors and the state tax commission.
